Effectiveness of an Arthroscopic Technique to Correct Supination Losses of 90° or More

DRUJ Capsular Release for Forearm Rotational Limitation: Surgical Technique and Case Series

BACKGROUND

Forearm stiffness can be caused by distal radioulnar joint (DRUJ) capsular contractures, which can occur after trauma such as a distal radius fracture. In this setting, a DRUJ capsular release may help improve forearm rotation, but the long-term functional outcomes remain unknown. The purpose of this case series is to investigate the short-term improvement in total pronosupination arc range of motion and long-term patient-reported outcomes (PROs) after DRUJ capsular release.

METHODS

We performed a retrospective review of consecutive patients who underwent DRUJ capsular release. Range of motion prior to surgery and at final short-term follow-up was collected and analyzed with a Wilcoxon signed-rank test. Patient-reported outcomes including QuickDASH and Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) scores were obtained as medians with interquartile range (IQR), while patient satisfaction was measured on a 4-point Likert scale.

RESULTS

Five patients met the inclusion criteria with a median short-term follow-up of 5.5 (IQR: 4.3-10.3) months. The median preoperative supination was 25° (IQR: 0°-35°), and the median postoperative supination was 50° (IQR: 40°-60°; P = .03). The median preoperative pronation was 45° (IQR: 10°-60°), and the median postoperative pronation was 70° (IQR: 60°-80°; P = .04). After the long-term median follow-up of 10.9 (IQR 9.7-11.2) years, all the patients were satisfied or very satisfied with the results of the surgery. The median QuickDASH score was 13.6 (IQR: 9.1-20.5), and the median PROMIS UE score was 46.5 (IQR: 43.8-47.7).

CONCLUSIONS

Distal radioulnar joint capsular release can improve pronation and supination in patients with posttraumatic forearm stiffness and is associated with high long-term patient satisfaction.

Wrist Arthrolysis: A Systematic Review of Open and Arthroscopic Techniques

Background  Wrist arthrolysis is a viable option in wrist stiffness and can be performed via open or arthroscopic techniques. Purpose  The aim of the study is to describe and evaluate the available techniques of open and arthroscopic arthrolysis of the radiocarpal joint and the distal radio ulnar joint (DRUJ) in posttraumatic wrist stiffness. Methods  A systematic literature search was performed in PubMed to identify studies reporting on open and arthroscopic wrist arthrolysis. Key words included "open wrist arthrolysis," "arthroscopic wrist arthrolysis," "post-traumatic wrist stiffness," and "DRUJ arthrolysis." Data were extracted independently by a pair of reviewers. Results  Overall, 637 studies were identified; 13 additional articles were found through previous publications (total 650 articles). A total of 612 records resulted after duplicates was removed. Fourteen studies were selected and only eight respected the inclusions criteria. One study focused on volar open arthrolysis and four studies on arthroscopic arthrolysis of the radiocarpal joint; two studies reported on open arthrolysis and two studies on arthroscopic DRUJ arthrolysis. Range of motion following open and arthroscopic wrist arthrolysis improved in all studies. Conclusion  Both arthroscopic and open arthrolysis can lead to similar and satisfactory results in radiocarpal joint and DRUJ stiffness.. Level of Evidence  This is a level 3a study.

Salvage procedure after malunited distal radius fractures and management of pain and stiffness

Indications for surgical treatment of distal radius fractures (DRF) remain controversial in the literature, especially in elderly patients. Complication rates after operatively treated DRF are low and well documented. These include malunion, degenerative osteoarthritis in the radiocarpal joint and subsequently pain and impaired hand function. If conservative treatment fails then salvage procedures are necessary. This review summarizes the therapeutic options available to treat degenerative osteoarthritis after malunited distal radius fractures, regardless of the initial operative or conservative treatment.

Anteromedial Release for Posttraumatic Flexion-pronation Contracture of the Wrist: Surgical Technique

Wrist stiffness can be a complication of trauma. A small percentage of patients fail to improve with nonoperative management and require operative intervention to regain range of motion and function. These group of patients can present with a soft tissue flexion-pronation contracture, which is hypothesized to be caused by capsular contraction of the distal radioulna joint, musculotendinous contracture of the flexor carpi ulnaris, contracture of the volar ulnar carpal ligaments and of the pronator quadratus muscle. This complication significantly restricts functional dart-thrower's range of motion and is highly disabling. A surgical option to manage this condition is release of pathologic structures with an anteromedial approach to the wrist. We describe a safe, effective, and reproducible technique to treat these patients.
