Wrist Arthroplasty

Background: Total wrist arthroplasty (TWA) is indicated to alleviate pain secondary to arthritis while preserving wrist motion. Despite vigilant measures, TWAs are susceptible to complications. The current case illustrates an array of preventable complications which are addressed through operative technique in a revision setting. Case presentation: The patient was a 72-year-old man who presented with chronic pain at the fourth carpometacarpal joint (CMCJ) and distal radioulnar joint with paresthesias in the median nerve distribution. Surgery was undertaken to address the following complications secondary to a previous TWA: impingement of the native distal ulna on the prosthesis, carpal tunnel due to metallosis and polyethylene synovitis, loose carpal component, and prominent screw at the fourth CMCJ. Surgical correction included open carpal tunnel release with extensive flexor tenosynovectomy, distal ulna resection and implant arthroplasty with shortening, revision of carpal component with bone grafting, and shortening of the ulnar screw to avoid crossing the fourth CMCJ. Within 6 months of the procedure, the patient reported resolution of neuropathic symptoms and pain-free motion of the wrist. Discussion: Preventable complications associated with TWA are individually highlighted. In addition, we compare and contrast our approach and surgical technique to current reported literature. Overall, we provide education and guidance to avoid possible TWA pitfalls. Conclusion: With this case report, we hope to increase TWA knowledge with emphasis on the requirements of judicious patient selection, preoperative planning, meticulous surgical technique, and complication awareness for subsequent optimization of wrist function, stability, and durability.

We studied whether mental health status is significantly correlated to patient reported functional outcomes and satisfaction after carpal tunnel release. Over a 7-year period, 809 patients completed Short Form-12 (SF-12) questionnaires which allowed calculation of the SF-12 mental component summary 1 year postoperatively, 780 (96%) completed a satisfaction questionnaire and 777 (96%) completed a QuickDisabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Median QuickDASH score was 55 preoperatively (interquartile range [IQR] 28) and 14 postoperatively (IQR 32). A total of 674 patients were satisfied. Patients with mental disability had worse QuickDASH scores (median 34, IQR 41) and a higher incidence of dissatisfaction (52/245, 21%) than those without mental disability (n = 9, IQR 20, 10%, both p < 0.001). Regression analyses indicated scores in the SF-12 mental component summary were significantly related to postoperative QuickDASH score ( p < 0.001) and satisfaction ( p = 0.02). We concluded that patients with mental disability report poorer outcomes and lower satisfaction rates; however, the majority still exhibit significant improvements and are satisfied.

Introduction: Aberrant positioning of the ulnar nerve volar to the transverse carpal ligament is a rare anatomic variation.Case Presentation: We present the case of a 55-year-old female with unique ulnar nerve anatomy that was discovered introperatively during carpal tunnel release.  The ulnar nerve was running directly adjacent to the median nerve in the distal forearm and as the median nerve traversed dorsal to the transverse carpal ligament (flexor retinaculum) to enter the carpal tunnel the ulnar nerve continued directly volar to this structure before angling towards Guyon’s Canal.  The unique ulnar nerve anatomy was successfully identified, carefully dissected and managed with a successful patient outcome.Conclusion: Variations of the anatomy at the level of the carpal tunnel are rare but do exist.  Awareness of these anatomic variations and adequate visualization of the ulnar nerve along with the surrounding structures is crucial to avoid iatrogenic injuries during carpal tunnel release.

Bearing Dislocation

The Oxford (Oxford® partial knee; Biomet) mobile bearing medial unicondylar knee replacement (OUKR) is a preferred choice by surgeons due to minimal blood loss, reduced pain, and better range of motion. Commonly observed complications include aseptic loosening, polyethylene wear, bearing dislocation, and periprosthetic fractures. A bearing dislocation can be prevented by ensuring that there is correct tracking of bearing during the trial reduction as well as no loss of entrapment. We present a case report in a 50-year-old patient undergoing bilateral OUKR wherein it was observed that the meniscal bearing upon the flexion of the knee joint had the tendency to dislocate. Upon revising the vertical tibial recut according to the anterior superior iliac spine, the meniscus was found to have a normal excursion. Mobile bearing dislocation is a unique complication of mobile bearing OUKR. Surgical technique is of paramount importance in ensuring a successful OUKR. The vertical tibial cut is made to accommodate the vertical wall of the tibial component. Meniscal displacement is quite a common complication and can occur due to multiple causes. Inaccurate vertical tibial cut may be one such reason leading to tibial dislocation.

Carpal Tunnel Release Surgery

This retrospective study examined whether the presenting complaint of numbness is relieved post-operatively in severe carpal tunnel syndrome and also assessed any correlation between outcomes of the first and second procedures in staged bilateral carpal tunnel releases. Carpal tunnel release (60 open and 38 endoscopic) was done in 49 patients with bilateral severe carpal tunnel syndrome. There was complete resolution of numbness post-operatively in 77% ( n = 75) of hands. The median post-operative time before complete resolution of numbness was 21 days (IQR 8 to 21; range 3 to 482). The likelihood of complete resolution of symptoms after the second carpal tunnel release in patients with complete resolution of symptoms after the first carpal tunnel release was 22 (95% CI: 4 to 131) times that of the likelihood of improvement in patients with incomplete resolution of symptoms after the first carpal tunnel release.

Objective To describe a new mini-invasive surgical technique for carpal tunnel release and to present clinical findings associated with using this technique. Methods Patients with idiopathic carpal tunnel syndrome without prior surgical treatment, who underwent a new minimally-invasive surgical technique using a specific surgical tool-kit developed by the author, were included. Prospective data were collected, including preoperative electrodiagnostic testing. The subjective condition of all patients was evaluated pre- and postoperatively with a five-level Likert-type scale (LS) and muscular strength was tested using a JAMAR dynamometer and pinch gauge. Results A total of 116 patients (157 hands/cases) underwent surgery performed by the author, and were followed for a mean of 40 months (range, 6 months–7 years). Of these, preoperative electrodiagnostic testing was performed in 112 patients (96.6%). No significant complications were reported. By three months, patients reported that they were satisfied or very satisfied in 147/149 cases (98.7%; LS grade I and II). Strength recovery at three months, based on the average of four measures, was 99.17% (range, 97.43–100.97%). Conclusions The described technique is minimally invasive, safe and simple to perform, and provides good results.

Wrist Arthroplasty

Salvage of failed total wrist arthroplasty by arthrodesis may be difficult because of bone loss and poor quality of bone and soft tissues. We examined the outcomes of wrist arthrodesis for failed total wrist arthroplasty in a retrospective study of 21 wrists in 17 patients. Clinical data, radiographs, patient-reported outcomes and DASH questionnaires were used. Thirteen women and four men had undergone total wrist arthroplasty at an average age of 55 years. The mode of failure was aseptic loosening in 13 wrists. The average time from the index arthroplasty to wrist arthrodesis was 7.6 years. Autograft and/or allograft bone graft was used in all of the wrists. Arthrodesis was achieved in 11 wrists and ten had a nonunion. Six arthrodeses underwent eight revisions for nonunion, with two achieving union. The mean DASH score was 29 in wrists that fused and 36 in those that did not fuse. Pain scores averaged 2.1 in the wrists that fused and 3.3 in the nonunion group. Most patients had clinical improvement.
