Total wrist arthroplasty with the Freedom® prosthesis: a short-term follow-up.

We retrospectively reviewed our series of primary total wrist arthroplasty with the Freedom® prosthesis. The primary outcome measure was revision, and secondary measures included radiographic loosening, pain, complications, movement range, grip strength and patient-reported measures. We reviewed 12 implants in 11 patients (mean age 59 years, range 45-80) with a mean radiological and clinical follow-up of 2.7 and 3 years, respectively. One radial component failed to integrate and was revised at Day 84. Four carpal components demonstrated areas of lucency. There was a statistically significant reduction in pain, and total flexion-extension increased. Despite high patient satisfaction on a ten-point visual analogue scale score (mean 8.7 out of 10), the mean patient-rated wrist evaluation, Quick Disabilities of the Arm, Shoulder and Hand and Patient Evaluation Measure scores were 52, 55 and 53, respectively. The Freedom® implant reduced pain and preserved wrist movement in our patients; however, annual surveillance is recommended due to the high incidence of early carpal component lucency.Level of evidence: IV.

A Systematic 10-Year Review of the Use of Arthroscopy in the Assessment and Treatment of Intercarpal Ligament Injuries Associated with Acute Distal Radius Fracture.

Background: To review the impact that arthroscopy has made on the assessment and treatment of intercarpal (scapholunate [SL] or lunotriquetral [LT]) ligament injuries associated with acute distal radius fractures (DRF). Methods: A systematic review of EMBASE, MEDLINE and COCHRANE databases for articles published between 2011 and 2021 was performed (PROSPERO ID: CRD42021273293) which included studies reported assessment and outcomes of intercarpal ligament injuries associated with acute DRF. Methodological quality was evaluated. The rate of concomitant injury detection, role of arthroscopy and different clinical outcome assessment measurements used were compared between studies. Results: A total of 20 articles were included with data from 1,346 patients (1,358 wrists). A total of 1,024 intra-articular fractures were included and 294 extra-articular fractures (40 not specified). There was a heterogeneous mix of studies; 10 comparative and 10 non-comparative. Some studies investigated initial assessment findings only, while others assessed radiological outcomes, functional outcomes or both domains over 0.3-99 months. The overall rate of SL ligament injury associated with DRF was 35.3%, while LT ligament injury overall was 18.2%. More frequent were concomitant triangular fibrocartilage complex (TFCC) injuries (44.8%), although this review did not aim to review these. The role of arthroscopy was reviewed, which included assistance in anatomic reduction of the articular surface and systematic inspection of the surrounding soft tissues. Included studies investigated either assessment or assessment and management of intercarpal ligament injury. Meaningful meta-analysis in this heterogeneous group of studies was not possible. Outcomes of comparative studies were described in detail. Conclusions: This review suggests that arthroscopy may have a role in improving reduction of intra-articular DRF and diagnosing and managing soft tissue injuries associated with such fractures. Randomised studies are needed to evaluate whether the detection of intercarpal ligament injury in acute distal radial fractures through arthroscopic assessment alters current management and improves clinical outcome. Level of Evidence: Level III (Therapeutic).

Outcomes of Multiple Digit Proximal Interphalangeal Joint Swanson Arthroplasty Done at a Single Operation.

Background: Proximal interphalangeal joint (PIPJ) arthroplasty using a Swanson implant is commonly used for the treatment of PIPJ arthritis despite newer implants being available. Many patients develop arthritis in more than one digit and some tend to have multiple digits operated on in their lifetime. There is paucity of literature on the outcomes of multiple PIPJ arthroplasty in one sitting. The aim of this study is to determine the outcomes of PIPJ arthroplasty using a Swanson implant done for multiple digits at one sitting. Methods: We retrospectively reviewed the outcomes of multiple Swanson PIPJ arthroplasty during a single operation from 2008 to 2018 in 13 patients (43 arthroplasties). We compared pre- and post-operative results of flexion/extension arcs, grip and pinch strength and questionnaires subsequently compared QuickDASH (Disabilities of Arm, Shoulder and Hand), Patient Evaluation Measure (PEM) and Visual Analogue Score (VAS) scores. Data were analysed with a Mann-Whitney U test. Results: Patients on average attended 5.6 hand therapy sessions over 5.1 months post-operatively. Average flexion/extension arc improved from 31.9° pre-operatively to 37.2° post-operatively. Average grip strength increased from 7.2 kg to 10.2 kg. The QuickDASH, PEM and VAS scores improved in keeping with the reported literature. There were no implant failures. Conclusion: We demonstrate similar outcomes for multi-digit Swanson PIPJ arthroplasty compared to the literature for single digit Swanson PIPJ arthroplasty. We conclude that multi-digit arthroplasty in a single operation is safe and effective. Level of Evidence: Level IV (Therapeutic).

Revision guided suture-button bone block stabilization of the shoulder in the presence of significant retained glenoid metalwork.

AIM: Positioning and fixation of the bone block during revision anterior stabilization of the shoulder, in the presence of significant retained glenoid metalwork, can be challenging. We present the results of a series of patients who underwent a revision bone block procedure secured with double suture buttons using a drill guide system, the position of which was calculated from a preoperative computed tomography (CT) scan. MATERIALS AND METHODS: We undertook a revision bone block stabilization of the shoulder, using a guided double suture-button fixation, in 10 patients with significant retained glenoid metalwork from previous procedures. A preoperative CT scan was used to determine a position for the guide to allow a safe drill trajectory that would avoid any retained metalwork. A coracoid transfer was undertaken in 4 patients and an Eden-Hybinette in 6. Patients were assessed preoperatively and at final follow-up clinically and using the Oxford Shoulder Instability Score and the Subjective Shoulder Value score. Bone block position and healing was assessed by a CT scan at 6 months. The median follow-up was 36 months (range, 24-47 months). RESULTS: There were 3 female and 7 male patients with a median age of 24.5 years (17-49 years). At final follow-up, the mean Oxford Shoulder Instability Score had decreased from 25.9 (range, 21-35) to 5.8 (range, 3-14) (P < .005). The mean Subjective Shoulder Value score had risen from 87.1 (range, 10-60) to 80 (range, 60-90) (P < .05). All of the patients considered their shoulder to be stable apart from 1 patient. There had been no redislocations. The bone block positioned in the glenoid lower quadrant had healed for all of the patients on CT at 6 months. CONCLUSION: Guided suture-button fixation of the bone block during revision anterior stabilization of the shoulder, in the presence of significant retained glenoid metalwork, provides a satisfactory outcome in terms of shoulder stability, graft position, and healing.
