title: The Extended Flexor Carpi Radialis Approach for Concurrent Carpal Tunnel Release and Volar Plate Osteosynthesis for Distal Radius Fracture.
abstract: OBJECTIVE
  To determine the relative benefits of an extended flexor carpi radialis (FCR) (eFCR) approach with prophylactic carpal tunnel release at the time of volar plate osteosynthesis for distal radius fracture via a single incision into the traditional volar Henry (VH) approach.
  
  
  METHODS
  This was a prospective cohort comparison of preoperative and postoperative median nerve function of 27 patients (15 eFCR and 12 VH) with unilateral, isolated distal radius fractures requiring open reduction internal fixation without preoperative acute carpal tunnel syndrome. Patients were operated on via either the eFCR or VH approach. The validated Levine-Katz Carpal Tunnel Questionnaire (symptom and functional severity scores) was administered and Semmes-Weinstein monofilament and 2-point discrimination testing were conducted preoperatively and at 6 weeks and 3 months postoperatively. Grip and pinch strength were measured at 6 weeks and 3 months. The groups were comparable in terms of age, sex, and fracture type and displacement.
  
  
  RESULTS
  Comparing across groups, there were no statistically significant differences in any outcome measured preoperatively or postoperatively. The eFCR and VH groups demonstrated significant improvement in functional severity scores, symptom severity, and grip strength. The symptom severity score improved to statistical significance at 6 weeks in the eFCR group and at 3 months in the VH group.
  
  
  CONCLUSIONS
  In this small comparative study, the eFCR approach was found to be safe and efficacious. There was no increased surgical morbidity, which suggests that this technique can be used safely for all patients undergoing volar plating and not just in cases of concurrent carpal tunnel syndrome. It allows easier retraction of carpal tunnel contents; therefore, it is our preferred approach.
