Outcome of open release for post-traumatic elbow stiffness.

BACKGROUND: Post-traumatic elbow stiffness can be caused by a tether and/or a block, and these structures can exist both anteriorly and posteriorly about the joint to prevent motion. The purpose of this article is to report the outcome of elbow release performed for post-traumatic stiffness by a single surgeon. METHODS: A retrospective review of charts and radiographs was performed on 52 case of patients who underwent open surgical treatment for post-traumatic elbow contracture by the senior author (RHN). The mean age of the group was 35.1 years. There were 32 men and 20 women. Contracture release surgery was performed at an average of 14 months from the time of injury. Indication for operative release was functional loss of elbow arc of motion that failed nonoperative therapy and splinting program. Follow-up was 18.7 months. Comparison of ranges of motion was performed with Student's paired t tests. RESULTS: The average extension-flexion arc of motion improved from 57 to 116 degrees and forearm rotation improved from 119 to 145 degrees postoperatively. Fourteen patients (27%) required closed manipulation under anesthesia, in the early postoperative period. Five patients required a second contracture release at an average of 12 months after the index release. Four patients failed because of painful motion (n = 2) and elbow instability (n = 2). Other complications included wound infection (n = 3), cubital tunnel syndrome (n = 3) and reflex sympathetic dystrophy (n = 1). CONCLUSIONS: Open elbow release with excision of tethers and blocks is a valuable procedure for post-traumatic stiffness. Recurrence in postoperative period is common but is responsive to manipulation under anesthesia and repeat releases.

Treatment of distal radius fractures with a low-profile dorsal plating system: an outcomes assessment.

PURPOSE: To evaluate objective functional and radiographic outcomes after internal fixation of acute, displaced, and unstable fractures of the distal aspect of the radius in adults by using a low-profile dorsal plating system. Our hypothesis was that the low-profile dorsal plating system would allow for a reduction of extensor tendon irritation and pain and provide stable osseous fixation. METHODS: Sixty consecutive unstable fractures in 59 patients were treated by open reduction internal fixation using a low-profile dorsal plating system. There were 29 type A, 14 type B, and 8 type C fractures (AO classification system). Fifty patients with 51 fractures returned for outcomes assessment by physical examination, plain radiographs, and completion of a validated musculoskeletal function assessment questionnaire. The minimum follow-up period was 1 year; the mean follow-up period was 24 months. Clinical evaluation was performed and plain radiographs were assessed for maintenance of immediate postoperative reduction and implant position. Objective functional assessment was obtained through the Disabilities of the Arm, Shoulder, and Hand questionnaire. RESULTS: Outcomes analysis showed no cases of extensor tendon irritation or rupture. Hardware removal was performed in 1 patient but no extensor tendon irritation or rupture was evidenced. The mean Disabilities of the Arm, Shoulder, and Hand score was 11.9; implant-related discomfort was minimal. All patients had an excellent (31 patients) or good (19 patients) result according to the scoring system of Gartland and Werley. The mean active range of motion was greater than 80% of that of the contralateral wrist in flexion/extension, pronation/supination, and ulnar/radial deviation. Extensor tendon function was unimpaired in all patients. Grip and pinch strength averaged 90% and 94% of the contralateral sides, respectively. Radiographic evaluation showed no change in fracture reduction or implant position. CONCLUSIONS: The treatment of distal radius fractures with a low-profile stainless steel dorsal plating system is a safe and effective method that provides stable internal fixation and allows for full extensor tendon glide and full metacarpophalangeal joint motion. Objective outcome testing showed uniformly good to excellent recovery of wrist and hand function in all patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.

Fractures of the distal aspect of the radius: changes in treatment over the past two decades.

Fractures of the distal end of the radius are among the most common orthopaedic injuries, and treatment of these fractures has changed over the course of time. Many fractures of the distal radius are in fact relatively uncomplicated and are effectively treated by closed reduction and casting. However, fractures that are either unstable and/or involve the articular surfaces can jeopardize the integrity of the articular congruence and/or the kinematics of these articulations. The goal of the treating physician should then be to restore the functional anatomy by a method that does not compromise hand function. The fracture pattern, degree of displacement, the stability of the fracture, and the age and physical demands of the patient determine the best treatment option. Over the past 20 years, there has been a development of more sophisticated internal and external fixation techniques and devices for the treatment of displaced fractures of the distal radius. The use of percutaneous pin fixation, external fixation devices that permit distraction and palmar translation, low profile internal fixation plates and implants, arthroscopically-assisted reduction, and bone grafting techniques including bone graft substitutes all have contributed to improving fracture stability and outcome.
