RESUMO
Background Severely destroyed wrists can be managed by combined radiocarpal and distal radioulnar joint (DRUJ) replacement that reduces pain while mobility is ought to be reserved. The combination of these arthroplasties is rarely reported in the literature. Purpose This article describes the clinical outcomes of six consecutive patients with both total wrist and Aptis DRUJ arthroplasty with a median follow-up of 50 months (range: 18-108 months). Patients and Methods Patients with a TWA combined with an Aptis DRUJ arthroplasty were retrospectively identified. The patients were treated between 2011 and 2020. Results The flexion-extension arc was slightly decreased in three cases while forearm rotation was improved in three patients. Pain was adequately reduced in four patients and significant pain was seen in two patients. Although three of four patients could not return to previous work, all patients claimed to be satisfied with the result of the procedure. Conclusion This article demonstrates the possible feasibility of this combined arthroplasty in patients with a destroyed and unstable wrist. Level of Evidence Level III.
RESUMO
Background Treatment of post-traumatic osteochondral defects in the radiocarpal and distal radioulnar joint with nonvascularized metatarsal articular bone grafting is an option to restore the joint (cartilage) surface and wrist function. Purpose To evaluate the clinical midterm results of 10 consecutive patients who were treated with a nonvascularized metatarsal bone graft for cartilage bone defects of the lunate facet, scaphoid facet, sigmoid notch, or the radial part of the ulnar head. Patients and Methods Patients with isolated osteochondral defects of the lunate facet, scaphoid facet, sigmoid notch, or radial part of the ulnar head, respectively, as a result of wrist trauma were retrospectively identified in a prospectively collected database. The patients symptoms were limited wrist motion and/or pain. Clinical results and complications were extracted from patient's medical files and two questionnaires consisting of the Patient-Rated Wrist Evaluation and additional questions regarding patient satisfaction and return to work and/or hobby. Results Minor complications occurred in three cases and required surgery. In five cases an acceptable donor site foot morbidity was seen at 1 year. One patient was not satisfied due to persistent wrist pain despite adequate range of motion. One patient could not return to its prior work. Another patient could not resume its hobby. Conclusion Retrospective evaluation of 10 cases with resurfacing of the scaphoid facet, sigmoid notch, and/or lunate facet, or radial part of the ulnar head has shown that osseointegration was possible without a vascular pedicle to the graft in all cases with a (mean) follow-up of 5 years. This technique may become an alternative treatment when implants become less available. Level of Evidence Level III.
RESUMO
High complication rates and surgical revision rates following Aptis implant placement have been reported in the literature. This study evaluates the performance of the Aptis implant of twelve patients using four-dimensional kinematic analysis. The (mean) follow-up was 58 months. Wrist motion, grip strength, and kinematic analysis of both arms were used to investigate possible causes of the reported complications. In nine cases (75%), the proximal to distal translation of the distal radius along the ulnar axis in the affected forearm was too little or absent. Significant correlations were found between postoperative extension and translation of the distal radius along the ulnar axis and between the radial deviation and combined error. The four-dimensional kinematic analysis suggests that the current design of the implant could lead to limited restoration of the position of the forearm rotation axis and the translation of the radius along the ulnar axis.
