.010) was independently associated with soft tissue complication after total wrist fusion. Seventy-two (33%) patients had a postoperative complication including symptomatic hardware ( n  = 16, 7.4%), implant failure ( n  = 11, 5.1%), infection ( n  = 11, 5.1%), nonunion ( n  = 8, 3.7%), and carpal tunnel syndrome ( n  = 4, 1.9%). Conclusion  Roughly one-third (33%) of the patients undergoing total wrist fusion experience a postoperative complication and 19% of the patients underwent a reoperation. Total wrist fusion of the dominant hand results in higher reoperation rates. The risk of a soft tissue complication after total wrist fusion is increased in smokers.Background  The palmaris tendon inserts into the palmar fascia and is positioned in close association with the transverse carpal ligament. Loading of this tendon has been demonstrated to increase carpal tunnel pressures. Purpose  The purpose of this study was to determine if a relationship exists between the palmaris tendon, carpal tunnel syndrome (CTS), and handedness. The sensitivity, specificity, positive predictive value, and negative predictive value for Schaeffer's test were calculated. Methods  A retrospective review of patient charts undergoing endoscopic carpal tunnel release was performed. Rates of palmaris longus agenesis (PLA) were compared to a population matched data set. Statistical analysis was performed using a one-proportion z -test. Schaeffer's test for the palmaris longus tendon was performed on all patients and compared to intraoperative confirmation. Results  A total of 520 carpal tunnel releases were performed in 389 consecutive patients. OGA inhibitor The frequency of PLA in this surgical cohort was significantly lower compared to the population matched dataset. No correlation between handedness and laterality of CTS or PLA was found. Schaeffer's test was evaluated to yield sensitivity (93.6%), specificity (100%), positive predictive value (100%), and negative predictive value (50.8%). Conclusion  The palmaris tendon was more prevalent in a population of patients undergoing carpal tunnel release. These findings can be used to provide further insight into the pathophysiology of CTS. While Schaeffer's test was accurate in detecting the palmaris longus tendon, a negative test was frequently incorrect. Further imaging is recommended in patients with a negative Schaeffer's test when the palmaris longus is desired for surgical utilization. Level of Evidence  This is a Level III, prognostic study.Background  Dorsal scaphoid translation (DST) has been demonstrated to occur in patients with complete scapholunate interosseous ligament (SLIL) tears. Radiographs and magnetic resonance imaging (MRI) have demonstrated ability to detect DST in patients with documented complete scapholunate (SL) disruption, but the relevance of this parameter to outcomes of reconstruction has not been determined. Purpose  The purpose of this article is to determine how radiographic parameters of SL dissociation correlate with postoperative pain and functional outcomes of SLIL reconstruction. Methods  We performed a retrospective review of prospectively collected data on a cohort of 14 patients who underwent SLIL repair or reconstruction. Preoperative data included radiographic measurements of carpal posture and alignment (SL angle, radiolunate [RL] angle, SL gap, and DST), self-reported measure of average pain on a numerical rating scale (NRS) of 0 to 10, and the patient rated wrist evaluation (PRWE) survey. Postoperatively, tRL angle, or SL angle. Level of evidence  This is a Level IV study.Background  Posttraumatic morphological changes have been described in the posterior interosseous nerve (PIN) after mild wrist trauma, and it has been suggested that posttraumatic nerve changes may contribute to wrist pain. PIN excision has shown to relieve pain in some patients with wrist osteoarthritis. However, is not known if PINs from osteoarthritic wrist have pathological features. Objective  The aim of this study was to investigate whether PINs from osteoarthritic wrists show morphological changes that are not present in healthy wrists. Materials and Methods  PINs resected from 15 osteoarthritic wrists were analyzed with light microscopy regarding morphological changes and compared with five asymptomatic controls without osteoarthritis. Results  No significant differences in fascicular area, myelinated fiber density or myelinated fiber diameter were found. However, most patients and controls exhibited some degree of pathology, and a few samples from both groups exhibited severe pathological changes. Conclusions  Our findings of morphological changes in both patients with osteoarthritis and asymptomatic controls suggest that pathological changes of unknown significance might exist in the general population in the PIN at wrist level. We believe that the observed structural nerve changes in the PIN are unlikely to contribute to the symptoms of pain. Further studies of the normal histological appearance of the terminal PIN are needed. Level of Evidence  This is Level II study.Background  Bridge plating for distal radius fractures is indicated for complex fractures with comminution, extensive articular involvement, and/or cases requiring immediate weight bearing. Bridge plate fixation of distal radius fractures is a well-documented treatment method; however, failures have been reported with repetitive loading through the bridged distal radius fracture. Plate design is implicated as a cause of plate fracture in select clinical studies but few mechanical tests comparing bridge plate designs have been reported. This study sought to determine the impact of plate design on bridge plates intended to allow for immediate weight-bearing. Methods  Axial static ( n  = 3) and dynamic testing ( n  = 3) was performed on three distraction plates designs bridge plate 1 (BP1) with central holes, bridge plate 2 (BP2) without central holes, and locking compression plate (BP3). Plates were loaded in axial compression with a simulated 10-mm fracture gap. Results  Significant static load differences were noted between all groups.
