Carpal Tunnel Release Using the Radial Sided Approach Compared With the Two-Incision Approach

Abstract

We compared carpal tunnel release using a radial sided approach (RCTR) with a two-incision approach with regards to complications, grip strength, and functional outcomes. Retrospective chart review was done and data was collected pre-operatively, and post-operatively at six weeks and three months. A total of 32 and 26 patients were included in the two-incision and RCTR groups respectively. At six weeks, the RCTR group showed an increased grip strength (+32.24%) while the two-incision group was weaker (-6.75%). Both groups showed an increased strength at three months, RCTR at 98.4% while the two-incision group was significantly lower at 38.6% increase. Both techniques provided improvement in outcome scores, with no statistical difference. RCTR was associated with a significantly earlier return of grip strength and had better grip strength at six weeks and three months post-operatively. Both techniques provided symptom relief and good functional outcome.

Role of pronator release in revision carpal tunnel surgery

“…At the wrist incision, the antebrachial fascia was opened in a proximal-to-distal direction, releasing the TCL, connecting the two limbs of the TCL incisions. Full exploration of the median was visualized via these two incisions [ 8 ].…”
