Overview

Elbow stiffness remains a challenging clinical problem with no ideal management solution [1]. Current treatment options for post-traumatic elbow stiffness range from conservative to surgical, exhibiting varying rates of success, invasiveness, and complications [8]. Functional improvements can be achieved through both nonsurgical and surgical strategies [1]. Recent advancements in biology and pathology may lead to future breakthroughs in the prevention and treatment of this condition [1].

Successful intervention depends on the quality of the joint and the extent of soft tissue damage [2]. The functional arc of motion serves as a frame of reference rather than an absolute goal for stiff elbow intervention [2]. In the setting of failed nonsurgical treatment, surgical release can yield sustained improvement of range of motion and patient quality of life [5]. A multinational initiative provides the first comprehensive clinical practice guideline for open arthrolysis in adult posttraumatic elbow stiffness [7].

Endoscopic capsulectomy is an effective procedure for adhesiolysis in severe elbow stiffness [11]. 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 [13]. Patients with stiff elbows who underwent arthroscopic arthrolysis achieved satisfactory clinical outcomes very early postoperatively [3]. Additional peripheral nerve block combined with a postoperative nerve block catheter in arthroscopic arthrolysis may enhance postoperative outcomes by achieving better functional range of motion, perhaps through reduced postoperative pain [23]. 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 [12], though it is accompanied by increased blood loss, longer operative time, extended hospitalization, and higher costs [12]. 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 [14].

Anatomy & Pathophysiology

Elbow stiffness involves both articular and periarticular tissues [10]. Successful intervention depends on the extent of soft tissue damage [2]. Treatment requires a thorough understanding of normal anatomy and etiological factors [4]. Because elbow contracture is challenging to treat, prevention of stiffness is paramount [15]. Pre-operative evaluations must determine whether articular surfaces and osteoarticular congruence are preserved [10].

Etiological Factors: Heterotopic ossification (HO) is a cause of elbow stiffness that can result from direct elbow trauma, brain injury, or thermal injury [29]. Surgical treatment of elbow HO leads to improved functional outcomes regardless of the etiology of bone formation [29].

Iatrogenic Risk Factors: Following operative fixation of distal humerus fractures, the following factors are associated with increased odds of dysfunctional elbow stiffness: * Orthogonal plate configuration [18] * Olecranon osteotomy [18] * Longer operative time [18]

Pediatric Considerations: In obstetric brachial plexus injury, the progression of elbow flexion contracture appears to level off after the age of 10 to 12 years [20]. Elbow flexion and forearm rotation contractures likely end at skeletal maturity [20].

Classification

Treatment of the stiff elbow requires a thorough understanding of normal anatomy and etiological factors to develop effective strategies [4]. In the setting of failed nonsurgical treatment, surgical release can yield sustained improvement of ROM and patient quality of life [5]. However, restoration of joint motion in the posttraumatic stiff elbow can be a difficult, time-consuming, and costly challenge [9].

Pre-operative evaluations in elbow stiffness should identify involved articular and periarticular tissues [10]. These evaluations must also determine whether articular surfaces and osteoarticular congruence are preserved [10]. Operative management of pediatric elbow contractures is effective [24].

Clinical Presentation

Elbow contracture presents a significant therapeutic challenge, establishing prevention as the paramount clinical priority [15].

Preoperative Assessment: The clinical evaluation must account for the fact that arthroscopic elbow contracture release outcomes vary significantly based on preoperative patient characteristics [21].

Investigations

Plain radiography: Standard imaging is essential for evaluating elbow stiffness. Orthogonal plate configuration, olecranon osteotomy, and longer operative time were associated with increased odds of dysfunctional elbow stiffness following operative fixation of distal humerus fractures [18].

MRI: Magnetic resonance imaging can assess soft tissue pathology, including ulnar nerve status. There is sound evidence that ulnar neuropathy has a negative effect on symptoms and disability in elbow stiffness [17].

CT: Computed tomography provides detailed bony architecture but specific diagnostic signs for stiffness are not detailed in the current evidence base.

Bone scan: No specific evidence supports the routine use of bone scans for investigating elbow stiffness.

Tomosynthesis: No specific evidence supports the use of tomosynthesis for investigating elbow stiffness.

Aspiration: No specific evidence supports joint aspiration as a diagnostic tool for elbow stiffness.

Laboratory: No specific laboratory markers are indicated for the investigation of elbow stiffness in the provided evidence.

Other Considerations: Functional improvements can be achieved with both nonsurgical and surgical strategies for elbow stiffness [1]. It is unclear which patients who have surgery for elbow stiffness will develop new ulnar nerve dysfunction [17].

Treatment

Non-Operative Management

Prevention of elbow contracture is paramount because established contracture is challenging to treat [15]. Static progressive and dynamic splinting are mainstays of nonsurgical treatment for posttraumatic elbow stiffness [19]. There is no statistically significant difference in outcomes between static progressive and dynamic splinting methods [19]. Static-progressive bracing is associated with improved range of motion in patients with post-traumatic and post-operative elbow stiffness at three months [22]. This intervention appeared safe and should be considered in all patients with post-traumatic or post-operative elbow stiffness [22]. However, increasing age may reduce the efficacy of static-progressive bracing in patients with extension deficits [22].

Operative Management

Indications: Surgical release can yield sustained improvement of range of motion and patient quality of life in the setting of failed nonsurgical treatment of the stiff elbow [5].

Pre-operative Evaluation: The functional arc of motion serves as a frame of reference rather than an absolute goal for successful intervention [2]. Pre-operative evaluations should determine whether articular surfaces and osteoarticular congruence are preserved [10].

Adjuncts: The use of a hinged external fixator in open arthrolysis is accompanied by increased blood loss, longer operative time, extended hospitalization, and higher costs [12].

Complications

Surgical release for stiff elbow can yield sustained improvement of range of motion and patient quality of life in the setting of failed nonsurgical treatment [5]. However, current treatment options for post-traumatic elbow stiffness have varying rates of success, invasiveness, and complications [8].

Nerve palsy: Ulnar neuropathy has a negative effect on symptoms and disability [17].

Recovery

Surgical release yields sustained improvement in range of motion and patient quality of life for patients with failed nonsurgical treatment [5]. Patients undergoing operative management of elbow stiffness secondary to heterotopic ossification maintain substantial reductions in pain, improved elbow range of motion, and increased overall elbow function [16].

Hinged External Fixator Considerations: The use of a hinged external fixator in open arthrolysis is accompanied by increased blood loss, longer operative time, extended hospitalization, and higher costs [12].

Rehabilitation Protocol: Treatment of bony encasement of the ulnar nerve secondary to heterotopic ossification leads to superior range of motion, improved or resolved ulnar neuropathy, and good to excellent long-term functional outcomes [25]. There is no statistically significant difference in outcomes between static progressive and dynamic splinting for posttraumatic elbow stiffness [19].
