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¶

• Close radiographic follow-up is recommended for nonsurgically treated minimally displaced olecranon fractures in children to monitor for further displacement [1].
• Nonoperative management of isolated displaced olecranon fractures yields satisfactory short-term and long-term outcomes in older, lower-demand patients [7].
• A majority of olecranon fractures heal uneventfully with good or excellent results, with a small loss of motion to be expected [4].
• Operative treatment of closed displaced olecranon fractures via open reduction and internal fixation results in excellent or good outcomes in 96% of individuals up to 25 years after the fracture [2].
• Low-profile double-plate osteosynthesis is a safe and effective alternative treatment for olecranon fractures, providing excellent subjective and objective clinical outcome measures [5].
• Both Kirschner wire tension band combined with anatomical locking plate and other operative procedures effectively treat Mayo type II olecranon fractures [8].
• Plating of the olecranon leads to predictable union, although lack of full extension is the most common complication, occurring in 39% of patients [17].
• Tension-band wiring (TBW) remains an effective treatment for appropriately selected olecranon fractures and outperformed plate osteosynthesis in the evaluated cohort [22].
• Excision of the olecranon fragment with repair of the triceps mechanism is supported as the preferred treatment method due to significantly less morbidity compared with internal fixation [25].
• The timing of fixation for displaced olecranon fractures does not significantly increase the rate of early complications or reoperations [13].
• Surgical treatment of olecranon fractures is associated with a high rate of complications, and patients undergoing revisions beyond implant removal had poorer functional outcomes [39].
• No significant differences in functional outcomes or secondary operations were found with respect to fracture type, gender, or surgical method in the context of olecranon fracture complications [39].
• Olecranon osteotomy represents a useful alternative for the treatment of fractures and nonunions of the distal humerus [41].

Anatomy & Pathophysiology¶

• Fixation of olecranon fractures must be secure enough to permit early motion to avoid significant stiffness of the elbow joint [10].
• In pediatric olecranon fractures, treatment with a sling resulted in all cases being free of symptoms and having a full range of elbow movement at 3 weeks [11].
• Increasing elbow flexion places the medial elbow in a position to carry a greater amount of load, which may be exacerbated during the final moments of the pitching motion [27].
• Individuals with elbow degenerative changes had no inferior subjective elbow function compared to those with normal radiographs, except for those with joint space reduction [29].
• Primary elbow instability and fracture morphology are prognostic factors for elbow function and development of arthrosis after operative treatment of olecranon fractures [35].
• The outcome of tension-band wiring may be compromised in the presence of elbow instability and associated fractures of the radial head and coronoid [38].
• A pathoanatomic approach using the CURL framework systematically evaluates key injury components (coronoid, ulna, radial head, and ligaments) to guide surgical planning for proximal ulna fracture dislocation [43].
• Accurate diagnosis of complex elbow fracture-dislocations, such as posterior Monteggia fractures and posterior fracture-dislocation of the proximal ulna, helps provide effective treatments and evaluate prognosis [44].
• The guiding principle in surgical techniques for olecranon fractures is to restore a congruent humeroulnar joint and allow restoration of upper extremity function [47].
• Technological advances and improved understanding of functional anatomy have led to an evolution in operative reconstruction of complex proximal ulnar and coronoid fractures [48].
• The proposed novel fragment-specific classification of complex olecranon fractures is anatomically based and considers the deforming forces from ligaments and tendons [49].
• The Subjective Elbow Value (SEV) shows a high correlation to the most commonly used scoring systems for outcome evaluation after elbow injury [51].
• A stable, functional elbow can be restored in most patients with proximal ulna fractures treated with open reduction and internal fixation [52].
• Targeting the proximal ulna's narrowest segment provides an effective approach for osteotomy when precise morphology is unknown [53].
• Radiographic measurements of normal elbows guide the surgeon to obtain a more reliable length of the olecranon and maintain articular geometry during fixation [54].

Classification¶

• The Mayo classification was designed to simplify categorization of olecranon fractures but does not achieve this goal due to poor reproducibility [26].
• Quantitative 3-dimensional computed tomography analysis further clarified the fracture morphology of Mayo type I, II, and III fractures [36].
• Fracture of the olecranon in a child is often only part of a complex injury to the bone and soft tissues around the elbow [19].
• The olecranon apophyseal ossification system, when combined with age and sex, successfully predicts peak height velocity within a year in 90% of cases, establishing a single lateral view of the olecranon as a simple alternative to more complex grading systems [40].

Clinical Presentation¶

• Olecranon fractures in children can displace further after initial nonsurgical treatment, necessitating close radiographic follow-up [1].
• Isolated displaced olecranon fractures (>2 mm) in elderly patients can be successfully treated nonoperatively [3].
• The incidence of olecranon fractures increased by 29% over a 20-year study period (1999–2018) in Denmark [6].
• Nonoperative management of isolated displaced olecranon fractures in older, lower-demand patients yields satisfactory short-term and long-term outcomes [7].
• Patients with olecranon fractures have essentially similar demographic characteristics compared to patients with distal radius fractures [9].
• All 10 pediatric cases treated with a sling were free of symptoms and had a full range of elbow movement at 3 weeks [11].
• Olecranon fractures in the elderly have higher than expected 1-year mortality rates [14].
• Isolated fractures of the olecranon occur after low-energy trauma, especially in older women (>65 years) [15].
• Fractures of the olecranon in children are often part of a complex injury to the bone and soft tissues around the elbow [19].
• Articular impaction is a common feature of geriatric olecranon fractures [20].
• The median incidence of post-traumatic osteoarthritis following isolated olecranon fractures is 19% at a median follow-up of 41 months [21].

Investigations¶

• Close radiographic follow-up is recommended for nonsurgically treated olecranon fractures [1].
• Some isolated displaced (>2 mm) olecranon fractures in elderly patients can be successfully treated nonoperatively [3].

Treatment¶

Nonoperative Management¶

• The literature on the treatment of olecranon fractures in elderly patients is limited [18].
• Nonoperative treatment is a reasonable option for displaced stable olecranon fractures in elderly patients [31].
• Displaced olecranon fractures in patients older than 70 years may be effectively managed with nonoperative measures to produce high satisfaction and functional range of motion [34].
• Aggregate data support the non-operative treatment of isolated undisplaced olecranon fractures with good results in pediatric patients [33].

Operative Management¶

• A majority of olecranon fractures heal uneventfully with good/excellent results with a small loss of motion to be expected [4].
• 96% of individuals with a closed displaced fracture of the olecranon treated by open reduction and internal fixation had excellent or good outcomes up to 25 years after the fracture [2].
• Fixation must be secure enough to permit early motion to avoid significant stiffness of the elbow joint [10].
• No one technique is suitable for the management of all olecranon fractures [16].
• Aggregate data support the operative treatment of pediatric olecranon fractures displaced ≥4 mm [33].
• Low-profile double-plate osteosynthesis is a safe and effective alternative treatment of olecranon fractures with excellent subjective and objective clinical outcome measures [5].
• Low-profile double-plate osteosynthesis for treating olecranon fractures resulted in good clinical outcomes [37].
• Tension band wiring (TBW) remains an effective treatment for appropriately selected olecranon fractures and outperformed plate osteosynthesis in the studied cohort [22].
• Internal fixation by cable pin system (CPS) is an effective method for olecranon fracture and is associated with a shorter healing time, fewer complications and better function than TBW [23].
• Plate has better efficacy and safety for Mayo II olecranon fractures [28].
• The nickel-titanium olecranon memory connector (OMC) could be an effective alternative to treat olecranon fractures [30].
• Excision of the fragment of the olecranon with repair of the triceps mechanism is supported as the preferred method of treatment of fractures of the olecranon due to significantly less morbidity compared with internal fixation [25].

Recovery¶

• All 10 cases of pediatric olecranon fractures treated with a sling were free of symptoms and had a full range of elbow movement at 3 weeks [11].
• Internal fixation by cable pin system (CPS) is an effective method for olecranon fracture and is associated with a shorter healing time, fewer complications, and better function than tension band wiring (TBW) [23].
