We report a case of an extradigital glomus tumour found in the forearm. A review of the literature suggests that extradigital glomus lesions in the upper limb may be more common than they are thought to be.
Background We prospectively evaluated the surgical anatomy during first dorsal compartment release for De Quervain's tenosynovitis, with special attention to the superficial branch of the radial nerve (SBRN). Additionally, the incidence of tendon instability during surgery was assessed.
Methods This prospective cohort study consisted of 130 De Quervain's patients undergoing first dorsal compartment release. The treating surgeons recorded the type of incision used, the number of abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendon slips, the number of SBRN branches encountered, additional subcompartments created by any septations, and active/passive tendon stability.
Results A singular first dorsal compartment was found in 37% of cases, whereas 55% of patients had two subcompartments and 8% had three. Multiple APL tendon slips (range: 1–4) were identified in 78% of patients. In contrast, a single EPB tendon was found in 92% of patients (range: 0–2). At least one SBRN was encountered in 61% of cases. Following surgery, instability was evident in 9% of patients, who had tendons perch with passive wrist flexion. In one of these patients (<1%), the tendons dislocated volarly out of the first dorsal compartment during active flexion.
Conclusions The anatomical findings in our relatively large, prospective study of De Quervain's patients undergoing first dorsal compartment release are consistent with previous smaller and/or retrospective studies. Overall, we expect to encounter the SBRN during first dorsal compartment release in more than 50% of patients but are unconcerned if it is not visualized during a careful approach. Tendon instability has an incidence of 9%; however, dislocation is rare (<1%).
Background Bilateral distal radius fracture (DRF) is an uncommon injury. We described the outcomes of 10 consecutive cases of bilateral DRF treated with open reduction and internal fixation (ORIF) at our institution.
Materials and Methods We retrospectively searched our electronic medical records data for all patients 18 years of age or older treated surgically for bilateral DRF over a 6-year period (2011–2016). Patient demographics, fracture classification, fixation method, postoperative complications, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) questionnaire scores, wrist range of motion (ROM), and radiographic measurements of X-rays at final follow-up were collected and analyzed.
Results Ten patients (8 women; 2 men; mean age: 63 years) with 20 fractures were assessed. A volar approach for ORIF was used in 90% of cases. Six of 20 (30%) wrists experienced postoperative complications and required hardware removal. Mean QuickDASH score was 24.8 at final follow-up. On average, ROM reached 58-degree extension, 52-degree flexion, 75-degree pronation, and 75-degree supination. Mean measurements of radial shortening, radial inclination, and volar tilt taken from final postoperative radiographs were 1.3 mm, 21.2 degrees, and 7.8 degrees, respectively.
Conclusion In bilateral DRF treated with concomitant ORIF, functional outcomes, recovery of wrist ROM, and restoration of radiographic parameters are comparable to those seen in patients with ipsilateral DRF.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
