AbstractDistal radius fractures (DRF) may trigger, reveal or decompensate acute carpal tunnel syndrome (CTS) in 0.5-21% of cases. Internal fixation and median nerve release must then be carried out urgently. Less invasive approaches have been described for both the median nerve release using an endoscopic device and for the DRF fixation using a volar locking plate. We assessed the feasibility of DRF fixation and median nerve release through a single, minimally-invasive 15mm approach on a series of 10 cases. We reviewed retrospectively 10 consecutive cases of DRF associated with symptomatic CTS in 8 women and 2 men, aged 57 years on average. CTS was diagnosed clinically. All patients were treated during outpatient surgery with a volar locking plate and endoscopic carpal tunnel release using a single 15mm minimally-invasive approach. In one case, arthroscopic scapholunate repair was also required. Six months after the procedure, all patients were reviewed with a clinical examination and a radiological evaluation. The average values for the clinical and radiological outcomes were as follows: pain on VAS 1.5/10; QuickDASH 14.3/100; flexion 90%; extension 90.6%; pronation 95.6%; supination 87.9%; grip strength 90.1%; 2PD test 5.2mm (4-8mm). Five complications occurred: two cases of temporary dysesthesia in the territory of the median nerve and one case of temporary hypoesthesia of the palmar branch of the median nerve, which had all completely recovered; two cases of complex regional pain syndrome type I, which were still active at 6 months. Despite its methodological weaknesses, our study is the only one to describe the technical feasibility of a single 15mm minimally-invasive approach for both internal fixation using a volar locking plate and endoscopic nerve release, with no serious complications. This technique should be added to the surgical toolbox of minimally-invasive procedures for the hand and wrist.Copyright © 2018 SFCM. Published by Elsevier Masson SAS. All rights reserved.
