This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview¶

• In the setting of failed nonsurgical treatment of the stiff elbow, surgical release can yield sustained improvement of range of motion and patient quality of life [1].
• Treatment choices for elbow stiffness must consider non-surgical management and various surgical options including arthroscopic or open capsular release, arthroplasty, and elbow replacement [2].
• Arthroscopic capsular release of the elbow is effective for restoring a functional arc of motion in the short term in most patients with extrinsic contractures [3].
• Arthroscopic elbow contracture release can improve function and range of motion, though outcomes may vary based on preoperative patient characteristics [4].
• Current literature provides state-of-the-art guidance on the management regarding prevention, evaluation, and treatment of elbow stiffness [5].
• Patients with stiff elbows who underwent arthroscopic arthrolysis achieved satisfactory clinical outcomes very early postoperatively [7].
• Current treatment options for post-traumatic elbow stiffness range from conservative to surgical, with varying rates of success, invasiveness, and complications [8].
• A multinational initiative provides the first comprehensive clinical practice guideline for open arthrolysis in adult posttraumatic elbow stiffness [9].
• A subset of pediatric patients with persistent stiffness following medial epicondyle fractures may benefit from additional interventions, including intensive therapy, transposition of the ulnar nerve, and open capsular release [13].
• In most cases, the current use of arthroscopy by experienced surgeons will produce results superior to those of open release given the proper indications [14].
• The use of a hinged external fixator in open arthrolysis for posttraumatic elbow stiffness may result in short-term improvements in flexion-extension range of motion [16].
• The use of a hinged external fixator in open arthrolysis for posttraumatic elbow stiffness is accompanied by increased blood loss, longer operative time, extended hospitalization, and higher costs [16].
• The dual mediolateral mini-open technique allows for a safe and effective release of stiff elbows through small incisions of 3–5 cm in length [18].

Anatomy & Pathophysiology¶

Bony Anatomy¶

• The elbow is a trocho-ginglymoid joint consisting of medial and lateral articulations that provide bony stability [28].
• The medial articulation involves the trochlea and the ulna within the greater sigmoid notch, forming the ulnohumeral hinged portion [28].
• The ulnohumeral articulation features highly congruent anatomy through almost 180° of articular contact, except for a bare area of the greater sigmoid notch devoid of cartilage [28].
• The coronoid process has medial and lateral facets that buttress the trochlea anteriorly [28].
• The sublime tubercle is located just distal and medial to the coronoid and serves as the attachment site for the anterior bundle of the medial ulnar collateral ligament [28].
• The lateral articulation involves the capitellum and radial head, forming the radiocapitellar joint [28].
• The radius is held in close approximation to the ulna at the proximal radioulnar joint by the annular ligament [28].
• The radial head is a concave elliptical structure covered with articular cartilage along the radiocapitellar joint and approximately 270° of the articular margin [28].
• The distal humeral articulation is angled 30° from the longitudinal axis [28].
• The axis of rotation is angulated 5° to 7° in the coronal plane relative to the epicondylar axis, with the medial side more distal than the lateral side [28].
• The ulna medially bends approximately 8° at 8 cm from the tip of the olecranon [28].
• The articulation to the tip of the coronoid is approximately 30° from the long axis of the ulna in the sagittal plane [28].

Ligaments and Soft Tissue¶

• Elbow stability is determined by primary stabilizers (ulnohumeral articulation, MUCL, LUCL complex) and secondary stabilizers (radiocapitellar articulation, common flexor tendon, common extensor tendon, joint capsule) [25].
• The medial ulnar collateral ligament is the primary valgus stabilizer of the elbow [29].
• The anterior bundle of the medial ulnar collateral ligament is the most important component for stability [29].
• The posterior bundle of the medial ulnar collateral ligament becomes taut at flexion beyond 120 degrees [29].
• The lateral ulnar collateral ligament serves as the posterolateral stabilizer of the elbow [29].
• Osborne’s ligament stabilizes the ulnar nerve in the cubital tunnel [29].
• The ligament of Struthers is a variant anatomy arising from the supracondylar process to attach to the medial epicondyle and is a potential site of median nerve compression [29].
• The joint capsule allows maximum distension at approximately 70 to 80 degrees of flexion [29].
• The anterior capsule attaches at a point approximately 6 mm distal to the tip of the coronoid [29].
• Tensile forces are present at the medial elbow, while compressive forces are present at the lateral elbow [29].

Muscles¶

• The brachialis is the strongest elbow flexor and attaches to the coronoid 11 mm distal to the tip [29].
• The biceps brachii inserts at the ulnar margin of the radial tuberosity and acts as a powerful supinator of the forearm [29].
• The triceps brachii is the primary elbow extensor and inserts on the olecranon process [29].
• The mobile wad consists of the brachioradialis, extensor carpi radialis longus, and extensor carpi radialis brevis [29].
• The flexor-pronator mass includes the pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris, and flexor digitorum superficialis [29].

Pathophysiology and Functional Range¶

• The normal elbow has a range of motion from 0° to 140° from extension to flexion [25].
• The normal elbow has a range of motion of 75° in pronation and 85° in supination [25].
• A functional arc of motion for the elbow is 100° for flexion and extension [25].
• A functional arc of motion for the elbow is 100° for forearm rotation [25].
• Successful intervention for a stiff elbow depends on the quality of the joint and the extent of soft tissue damage [11].
• The functional arc of motion serves as a frame of reference rather than an absolute goal for stiff elbow treatment [11].
• Treatment of the stiff elbow requires a thorough understanding of normal anatomy and etiological factors to develop effective strategies [10].

Classification¶

• The S.T.I.F. classification system highlights the aetiology of elbow stiffness [51].
• The S.T.I.F. classification system provides a framework to better understand the natural history of elbow stiffness [51].
• The S.T.I.F. classification system provides a framework to direct surgical management of elbow stiffness [51].
• The S.T.I.F. classification system provides a framework to predict clinical outcomes for elbow stiffness [51].
• Influencing factors must be taken into consideration for proper surgical indication and prognosis when using the S.T.I.F. classification system [51].
• The S.T.I.F. classification system is beneficial for research because identifying homogenous patterns of stiffness allows for more appropriate comparison between different treatment options [51].
• Based on the S.T.I.F. classification system, a treatment algorithm can be proposed that includes the severity of the disorders as a guide to surgical treatment [51].
• Based on the S.T.I.F. classification system, a treatment algorithm can be proposed that includes the severity of the disorders as a guide to the preferred operative approach (open or scope) [51].
• The prevalent types of stiffness identified by the S.T.I.F. classification system could be applied in the future to Artificial Intelligence to help in diagnosing the cause of elbow stiffness [51].

Clinical Presentation¶

• Elbow stiffness is a challenging problem with no ideal management solution [6].
• Elbow contracture is challenging to treat, and therefore prevention is of paramount importance [17].
• Restoration of joint motion in the posttraumatic stiff elbow can be a difficult, time-consuming, and costly challenge [15].
• Successful intervention for stiff elbow depends on the quality of the joint and the extent of soft tissue damage [11].
• The functional arc of motion serves as a frame of reference rather than an absolute goal for stiff elbow intervention [11].
• Conservative treatment is indicated for patients that have elbow stiffness due to heterotopic ossification for less than six months [22].
• Current non-surgical treatment measures for elbow stiffness due to heterotopic ossification include physical therapy and manipulation under anesthesia in order to restore the range of motion of the involved joint [22].
• Non-surgical options for heterotopic ossification have limited effects and can be used mainly in cases that cause a small limitation of range of motion [22].
• Surgical options are necessary if nonoperative management fails to restore the elbow function and range of motion after 6 months in patients with heterotopic ossification [22].
• Surgical excision of ectopic bone and contracture release, if present, are the most common surgical options in elbow heterotopic ossification management [22].
• Arthroscopic elbow contracture release can improve function and range of motion, although outcomes may vary based on preoperative patient characteristics [4].
• Although both open and arthroscopic techniques may produce satisfactory results, the current use of arthroscopy by experienced surgeons will produce results superior to those of open release given the proper indications [14].
• Operative management of pediatric elbow contractures is effective [23].
• Patients undergoing operative management of elbow stiffness secondary to heterotopic ossification maintained substantial reductions in pain, improvement in elbow range of motion, and increased overall elbow function [12].
• Treatment of bony encasement of the ulnar nerve secondary to heterotopic ossification of the elbow leads to superior range of motion, improved or resolved ulnar neuropathy, and good to excellent long-term functional outcomes [24].
• Delayed-onset anterior interosseous nerve palsy can develop one week after open elbow contracture release, likely due to a stretch injury [26].

Investigations¶

History and Physical Examination¶

• The history for elbow stiffness evaluation includes the duration of the contracture, initial injury, previous surgical procedures, trials of splinting/therapy/injections, surgical complications, and patient work/life demands [34].
• Physical examination must assess the function of the shoulder, wrist, and hand [34].
• The soft tissue surrounding the elbow should be examined for previous skin incisions, grafts, eschar, or infection [34].
• Active and passive flexion, extension, supination, and pronation should be evaluated using a goniometer for accurate measurement [34].
• The contralateral elbow should be examined for comparison during range of motion assessment [34].
• If the elbow has less than 90° to 100° of flexion, the posterior bundle of the medial collateral ligament is contracted and must be released to restore flexion [34].
• Pain assessment during the mid-arc or at terminal ends of motion helps distinguish intrinsic disease from contracture, as mid-arc pain is more common with intrinsic disease and may not improve with contracture release alone [34].
• The ulnar nerve is of utmost importance in the neurovascular examination due to its anatomic proximity to the elbow [34].
• Electromyography and nerve conduction velocity studies should be performed if there is any question about neurologic dysfunction [34].
• An assessment for ulnar nerve subluxation should be performed, as subluxation is a relative contraindication for arthroscopic procedures due to the risk of iatrogenic nerve injury [34].
• The surgeon must verify if the ulnar nerve has been transposed if there is a history of prior surgical procedures [34].
• Successful intervention for stiff elbow depends on the quality of the joint and the extent of soft tissue damage, with the functional arc of motion serving as a frame of reference rather than an absolute goal [11].

Imaging¶

• Radiographs should always be obtained for the evaluation of elbow stiffness [34].
• Standard radiographic views include AP, lateral, and oblique views, with serial radiography used as follow-up when heterotopic ossification is present [34].
• Primary bony landmarks assessed on radiographs include the ulnohumeral joint, coronoid process, radial head, capitellum, radiocapitellar joint, olecranon tip, coronoid/olecranon fossae, and trochlear ridge [34].
• CT is helpful for assessing malunion architecture and the location and pattern of osteophytes or loose bodies [34].
• Three-dimensional CT is used to check for heterotopic ossification [34].
• CT is not necessary when the stiffness is entirely soft-tissue related, but is beneficial if any joint incongruity or abnormal bony anatomy is present [34].
• MRI can be used to evaluate ligaments and tendons but is rarely indicated for elbow stiffness [34].
• The normal elbow has a range of motion from 0° to 140° from extension to flexion and 75° and 85° in pronation and supination respectively [25].
• A functional arc in each plane is 100° for flexion and extension and forearm rotation [25].
• Elbow stability is determined by primary stabilizers (ulnohumeral articulation, MUCL, LUCL) and secondary stabilizers (radiocapitellar articulation, common flexor tendon, common extensor tendon, joint capsule) [25].

Treatment¶

General Principles and Indications¶

• Elbow stiffness is a challenging problem with no ideal management solution; however, functional improvements can be achieved with both nonsurgical and surgical strategies [6].

Arthroscopic Release¶

• Arthroscopic elbow contracture release can improve function and range of motion; however, outcomes may vary based on preoperative patient characteristics [4].
• Although both open and arthroscopic techniques may produce satisfactory results, the authors believe that in most cases the current use of arthroscopy by experienced surgeons will produce results superior to those of open release given the proper indications [14].
• Additional peripheral nerve block combined with a postoperative nerve block catheter in arthroscopic arthrolysis in cases of elbow stiffness may be an opportunity to enhance postoperative outcomes by achieving better functional ROM, perhaps through reduced postoperative pain [48].

Open Release and Techniques¶

• This multinational initiative provides the first comprehensive clinical practice guideline for open arthrolysis in adult posttraumatic elbow stiffness [9].
• The use of a hinged external fixator in open arthrolysis for posttraumatic elbow stiffness may result in short-term improvements in flexion-extension range of motion but is accompanied by increased blood loss, longer operative time, extended hospitalization, and higher costs [16].
• The most common reason for a failed contracture release is a failure on the part of the surgeon to abandon an orthodox method in favor of a less assured technique or to use a single anatomic approach to the joint when the potential gain in motion is not achieved at the time of surgery [40].
• The operative contracture release requires a progressive, adaptive surgical approach, and the surgeon must safely increase the exposure in order to excise the offending fibrosis on nearly all aspects of the joint, anteroposterior and mediolateral [40].
• If an uncomplicated, simple dislocation has caused a 30-degree flexion contracture, arthroscopic capsular excision may be sufficient [40].
• The best care for a given patient with a contracture is the most minimal necessary surgery, including minimal anatomic exposure, and rehabilitation to achieve the desired result [40].
• A patient with a range of 40 to 105 degrees and heterotopic ossification will usually require exposure of the capsule for complete excision from both the medial and lateral approaches but not necessarily hinged fixation [40].
• In a circumstance with more massive heterotopic ossification, hinged external fixation may be necessary to stabilize the elbow postoperatively and permit immediate motion with intermittent passive stretch [40].
• The surgeon should be prepared to extend the exposure or approach the joint from an additional direction if full passive motion is not achieved on the operating table [40].
• In older patients with suspected cartilage damage or avascular bone, total elbow replacement should be available and discussed before surgery [40].

Outcomes and Complications¶

• Overall, patients maintained substantial reductions in pain, improvement in elbow range of motion, and increased overall elbow function after operative management of elbow stiffness secondary to heterotopic ossification [12].
• The gain in range of motion for open arthrolysis was 51° [19].
• The gain in range of motion for arthroscopic arthrolysis was 40° [19].
• The gain in range of motion for open arthrolysis with external fixation was 88° [19].
• The gain in range of motion for open arthrolysis with distraction arthroplasty was 56° [19].
• The average percentage of complications for open arthrolysis was 23% [19].
• The average percentage of complications for arthroscopic arthrolysis was 5% [19].
• The average percentage of complications for open arthrolysis with external fixation was 73% [19].
• The average percentage of complications for open arthrolysis with distraction arthroplasty was 58% [19].

Complications¶

• The use of a hinged external fixator in open arthrolysis is accompanied by increased blood loss [16].
• The use of a hinged external fixator in open arthrolysis is accompanied by longer operative time [16].
• The use of a hinged external fixator in open arthrolysis is accompanied by extended hospitalization [16].
• The use of a hinged external fixator in open arthrolysis is accompanied by higher costs [16].
• Current treatment options for post-traumatic elbow stiffness have varying rates of complications [8].

Recovery¶

• Surgical release of the stiff elbow can yield sustained improvement of range of motion and patient quality of life in the setting of failed nonsurgical treatment [1].
• Arthroscopic capsular release is effective for restoring a functional arc of motion in the short term in most patients with extrinsic contractures [3].
• Functional improvements can be achieved with both nonsurgical and surgical strategies for elbow stiffness [6].
• Treatment for bony encasement of the ulnar nerve secondary to heterotopic ossification of the elbow leads to superior range of motion, improved or resolved ulnar neuropathy, and good to excellent long-term functional outcomes [24].
