What you're feeling

Olecranon bursitis means the small cushioning sac at the point of your elbow has become swollen. That sac, called the bursa, normally lets skin glide smoothly over the bone. When it flares up, you notice a soft, sometimes tender lump right over the tip of the elbow.

The swelling is usually the thing you see first. It can come up quickly over a day or two, or slowly over weeks. Leaning on that elbow makes it worse, so desk work, resting your arm on a chair arm, or sleeping with the elbow bent under you can all aggravate it. Many people find it aches at night, especially if they sleep on that side. Straightening the arm out and taking pressure off the point of the elbow tends to settle it.

Everyday tasks that bend the elbow against resistance or press on the tip become awkward. Pushing yourself up from a low chair, loading the dishwasher, carrying shopping bags against your forearm, or resting your elbow on a table while you read can all be uncomfortable. Reaching overhead may pull on the swollen area too.

The swelling itself is not always simple wear and tear. Sometimes it comes from an infection in the sac, which usually makes the skin over the elbow red, warm and more painful. Sometimes it comes from crystals in the joint, a condition called gout, especially if you have had similar attacks before or the other elbow is affected as well. Swelling here can also be linked with inflammatory joint conditions such as rheumatoid arthritis, which typically affects several joints on both sides of the body at once.

Because these causes can look alike, it is not always easy to tell them apart from the outside. If your elbow is hot, red or very painful, or the swelling has hung around for weeks without settling, it is worth having it looked at properly so the right treatment can be started.

What's actually happening

At the tip of your elbow sits a small sac of fluid called the bursa. Think of it as a thin cushion, like a padded pouch between the skin and the bone. Its job is to let the skin slide smoothly over the bone every time you bend or straighten your arm.

With olecranon bursitis, that cushion becomes inflamed and swells up with extra fluid. This usually happens after repeated small knocks or pressure on the point of the elbow, the kind that comes from leaning on hard surfaces day after day. The sac can also simply enlarge from friction over time. The lump you can see and feel is the swollen sac itself, and the tenderness comes from the inflamed tissue around it.

Sometimes the swelling is not just irritation. The sac can become infected, which is why an infected bursa tends to be hot, red and more painful than one that is merely inflamed. Crystals from gout can settle in the sac, and inflammatory conditions such as rheumatoid arthritis can cause swelling and small firm lumps over the same spot. Because these causes look so similar from the outside, telling them apart can take a proper examination.

The bone at the tip of the elbow, called the olecranon, sits just under the skin with very little padding around it. That exposed position is exactly why it picks up knocks so easily, and why the bursa above it takes so much of the wear. The same bone also anchors the tendon of the muscle at the back of your arm, the one that straightens your elbow, so problems around this small area can affect how the whole elbow feels and moves.

What we can do about it

Dr Kieran Hirpara, an upper-limb surgeon at Mater Private Hospital Rockhampton, starts with the least invasive options that suit your condition. Patients are generally referred to our clinic by their GP; if a physiotherapist has suggested you see us, you will still need a referral from your GP in order to be eligible for the Medicare rebate. At your first visit we take a history, examine your elbow and arrange imaging such as ultrasound or MRI scans if it will help. An MRI scan uses magnets to build detailed pictures of the soft tissues, and it is good at showing how swollen the sac is and how much fluid it holds. Imaging can also pick up other problems hiding behind the swelling, which matters because different causes need different treatment.

For most long-standing cases, we begin with simple supportive care. That means ice, compression with a bandage or sleeve, protective padding over the point of the elbow, and changing the activities that keep aggravating it. Taking pressure off the tip of the elbow is often the single most useful change you can make. Physiotherapy aims to settle the irritation and rebuild comfortable movement without provoking the swelling. We give this approach a fair trial before thinking about anything further, because non-operative care works well for most people and avoids the risks that come with needles or surgery.

If the sac is infected, we treat that infection directly. Uncomplicated infection in this sac can usually be settled with medication alone, without needing the sac removed. We also keep a close eye on people with rheumatoid arthritis, because the elbow joint itself can occasionally be involved at the same time as the bursa, and that changes the treatment.

Surgery is not our usual first move for this condition. Most surgeons hold off on operating early, because a wound over this prominent bone can be slow to heal and can sometimes leave a sinus, a small channel that keeps draining. When non-operative care has not given enough improvement and the swelling keeps coming back, we consider removing the inflamed sac, an operation called bursectomy. Where suitable, we can do this through a few small cuts using a tiny camera, an approach called endoscopic surgery. That avoids a long wound directly over the sensitive point of the elbow. Whether surgery is right for you is a decision we make together, weighing what you want to get back to against what each option involves.

What to expect

For most people, this swelling settles with simple care. Taking pressure off the point of your elbow, protecting it with padding and easing back on aggravating activities gives the sac a chance to calm down. Non-operative treatment is generally more effective and safer than surgery for this condition, and most people never need an operation. If the sac is infected but the infection is straightforward, treating it with medication alone usually works, and the swelling can often be managed without draining it or removing the sac.

Without that care, or if the same pressures keep up, the swelling tends to persist or keep coming back. Some people find it hangs around for weeks without settling. If your elbow stays swollen for a long time, it is worth having it reassessed, because a swelling that will not settle can occasionally point to a less common cause that needs its own treatment.

When non-operative care has had a fair go and the swelling still keeps returning, surgery to remove the inflamed sac becomes an option. It is a decision not taken lightly, and it is usually held back until simpler measures have failed. Where surgery is done for this stubborn type of swelling, people tend to see real improvement in how their elbow feels and functions. Removing the sac through a few small cuts with a tiny camera has been associated with minimal postoperative pain and rapid recovery, with no recurrences or wound-healing complications needing a return to theatre in the patients reported. Even so, surgery here is not foolproof: about 11.5% of people who have the sac removed need a further operation later on. There is also a small chance the swelling comes back even after surgery.

Recovery after surgery is usually straightforward, but a wound over this bony point can be slow to heal, which is one reason surgeons prefer to avoid operating early. Most people get back to comfortable, everyday use of the elbow within weeks rather than months. Your surgeon will talk you through what recovery would look like for you if surgery ever becomes part of the plan.

When to see someone

Most swelling over the point of the elbow settles with rest and simple care. See your GP if the lump keeps growing, or if it has not settled after a few weeks of taking pressure off the elbow.

Some causes need to be sorted out quickly. Go to an emergency department if the skin over the elbow is hot, red and very painful, because that can mean the sac is infected and infection here needs same-day assessment. Ask for a specialist review if you have had gout attacks before, if the other elbow is swollen as well, or if several joints on both sides of your body are affected, since these point towards gout or an inflammatory condition such as rheumatoid arthritis rather than simple irritation. Telling an infection from gout can be difficult from the outside, so do not try to work it out yourself.

In more depth

Advanced reading: the deeper science (optional)

This section goes further than you need for your own treatment decisions. Olecranon bursitis is worth the extra reading because two of the things most instinctively done about it, draining the swelling with a needle, and injecting steroid into it, have evidence against them.

Draining it can be the thing that causes the problem

The intuition is strong: there is fluid, so remove the fluid. The trial data point the other way. In a comparison of management strategies for uncomplicated septic olecranon bursitis, empirical treatment without aspiration was effective, with no patients requiring bursectomy, while in the traditional aspiration group, 8 of 11 patients went on to need surgical removal of the bursa [1].

That is a striking difference from a small series, and it should be read with that caution. But the mechanism is not mysterious. The bursa sits directly under thin skin over a bony point that takes every knock and every lean on a desk. Putting a needle through that skin creates a tract, and a tract over a pressure point is slow to seal and can keep discharging.

The general reviews agree on direction. Based primarily on level IV evidence, non-surgical management is significantly more effective and safer than surgical management [2].

Steroid injection carries risk without improving the outcome

This one is stated unusually plainly in the literature. For aseptic bursitis, corticosteroid injection is associated with significant risks without improving the outcome [2].

The risks are specific to the site: skin atrophy and depigmentation over a subcutaneous bony prominence, and infection introduced into a space that is difficult to clear. Elsewhere in the upper limb a steroid injection is a reasonable step when simpler measures fail. Here the evidence does not support it, and that difference is worth knowing if it is offered.

Surgery is a genuine last resort, with a measurable failure rate

Where bursectomy is performed, it does not reliably end the story. The revision rate after bursectomy was 11.5%, and revision was more frequent in patients with rheumatoid arthritis, diabetes, a history of bursitis on either elbow, and in women [3].

Those risk factors describe the situations in which the bursa is likely to reform: an inflammatory or metabolic driver that surgery does not remove, or a demonstrated tendency of that individual's tissue to produce the problem. For recurrent cases, intrabursal doxycycline sclerotherapy, deliberately scarring the space closed rather than excising it, has been described as an alternative in a series of 45 elbows [4].

What actually settles it

The unglamorous answer is protection and time. Because the bursa is irritated mechanically by pressure on the point of the elbow, the treatment that addresses the cause is removing that pressure: padding, and changing the habit of resting on the elbow, sustained for longer than feels necessary. Most cases settle [5], and the interventions above are largely attempts to shorten a course that resolves anyway, which is precisely why an intervention carrying its own risk needs to clear a high bar here.

Anatomy & Pathophysiology

Bony Anatomy

  • The olecranon and the coronoid process form the greater sigmoid notch, which articulates with the trochlea of the distal humerus [19].
  • The intrinsic anatomy of the greater sigmoid notch allows flexion/extension movement of the elbow joint and provides stability for the elbow [19].
  • The olecranon serves as the insertion for the triceps tendon, which blends with the periosteum of the proximal ulna [19].
  • The exposed position of the olecranon renders it vulnerable to direct trauma and violent muscular contractions from the triceps [19].
  • In children, the olecranon is predominantly cartilage, particularly in younger children, which reduces the chance of fracture occurring with a direct blow [20].
  • The thick periosteum and relatively thin metaphyseal cortex of the olecranon in children predispose it to minimally displaced greenstick fractures [20].

Pathophysiology

  • Olecranon bursitis is a condition where the bursal cavity, superficial to the olecranon, becomes inflamed [13].
  • Olecranon bursitis can occur with or without infection [13].
  • Olecranon bursitis is often predisposed by repeated minor trauma from external pressure [13].
  • The olecranon bursa sometimes becomes enlarged as a result of pressure or friction [27].
  • When the olecranon bursa is painful, the cause is more likely to be infection, gout, or rheumatoid arthritis [27].
  • Gout is suspected in olecranon bursitis if there is a history of previous attacks, if the condition is bilateral, if there are tophi, or if X-ray shows calcification in the bursa [27].
  • Rheumatoid arthritis causes both swelling and nodularity over the olecranon [27].
  • In almost all cases of rheumatoid arthritis affecting the olecranon, it is associated with a typical symmetrical polyarthritis [27].
  • In the late stages of rheumatoid arthritis, erosion of the elbow joint may cause marked instability [27].

Classification

  • Olecranon bursitis has been given pseudonyms relating to the repeated minor trauma from external pressure that often predisposes [13].
  • Traumatic lesions of the olecranon bursa are common injuries associated with a high risk of complications [14].

Clinical Presentation

  • Olecranon bursitis is a common condition where the bursal cavity, superficial to the olecranon, becomes inflamed [13].
  • Olecranon bursitis can occur either with or without infection [13].
  • Due to multiple aetiologies, olecranon bursitis can present to any medical specialty with reasonable frequency [13].
  • When the olecranon bursa is also painful, the cause is more likely to be infection, gout, or rheumatoid arthritis [27].
  • Gout is suspected if there is a history of previous attacks, if the condition is bilateral, if there are tophi, or if X-ray shows calcification in the bursa [27].
  • In almost all cases of rheumatoid arthritis-associated olecranon bursitis, the condition is associated with a typical symmetrical polyarthritis [27].
  • Pyoderma gangrenosum must be considered in the differential diagnosis whenever a patient presents with ulcerative cutaneous lesions that resemble an infectious process such as olecranon bursitis [38].

Investigations

  • MR imaging is probably the method of choice for determining both the development of the bursae and their fluid content [44].

Treatment

Non-Operative Management

  • The first treatment line for olecranon bursitis is conservative, including ice, rest, anti-inflammatory and analgesic drugs and, occasionally, bursal fluid aspiration [25].
  • More recent literature demonstrates adverse effects of intrabursal injections and surgery compared with noninvasive management for initial treatment of nonseptic olecranon bursitis [18].
  • Hydrothermal ablation at temperatures between 50C and 52C is a safe treatment option for recurrent or chronic olecranon bursitis [34].
  • Hydrothermal ablation for recurrent or chronic olecranon bursitis has fewer complications than open bursectomy and comparable efficacy [34].

Operative Management

  • Open bursectomy appears to give satisfactory results for chronic olecranon bursitis [3].
  • Endoscopic olecranon bursectomy provides a satisfactory view with less morbidity than the open method while avoiding a wound over the sensitive point of the olecranon [15].
  • Bursal suture repair is a viable alternative to bursectomy in selected patients with chronic traumatic olecranon bursitis, combining functional and cosmetic benefits [11].
  • Excision has been curative for all lesions of the olecranon bursa, whereas multiple medications have been tried for cutaneous and systemic infections without clear-cut success [17].

Surgical Complications and Outcomes

  • More recent literature demonstrates adverse effects of surgery compared with noninvasive management for initial treatment of nonseptic olecranon bursitis [18].
  • Surgeons are reluctant to perform surgical excision as first-line treatment for chronic olecranon bursitis due to the fear of causing a chronic draining sinus or infection [45].

Infection and Atypical Etiologies

Recovery

  • Nonsurgical management of olecranon bursitis is significantly more effective and safer than surgical management [4].
  • 8 of 11 patients in the traditional aspiration group required bursectomy [7].
  • Bursal suture repair combines functional and cosmetic benefits [11].
  • The extrabursal endoscopic approach provides a satisfactory view with less morbidity than the open method [15].
  • The extrabursal endoscopic approach avoids a wound over the sensitive point of the olecranon [15].
  • Excision has been curative for all lesions of the olecranon bursa [17].
  • Multiple medications have been tried for cutaneous and systemic infections without clear-cut success [17].

If the licensor's permission is not necessary for any reason--for example, because of any applicable exception or limitation to copyright--then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable.

By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.

j. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

k. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
