Reconstruction of Digital Nerve Lesions With Muscle-in-Vein Conduits
- Conditions
- Peripheral Nerve Injury Upper Limb
- Registration Number
- NCT04788030
- Lead Sponsor
- BG Trauma Center Tuebingen
- Brief Summary
Muscle-in-vein conduits (MVCs) provide an alternative for bridging digital nerve defects when tension-free suture is not possible. Low donor site morbidity and absence of additional costs are favorable advantages compared to autografts or conduits. 37 patients with 43 defects of proper palmar digital nerves were retrospectively enrolled. Primary repair by MVCs was performed in 22 cases while 21 underwent secondary reconstruction. Recovery of sensibility was assessed by static and moving two-point discrimination (2PDs, 2PDm) and Semmes-Weinstein monofilaments (SWM). Results were compared with contralateral side serving as intraindividual control. Outcome data were stratified according to international guidelines and evaluated for differences in terms of age, gap length, time of reconstruction and concomitant injuries.
