Abstract：
Aponeurectomy remains the reference standard treatment for digit tethering by palmar fascial cords in Dupuytren\'s disease but is associated with a substantial complication rate. An alternative technique decreases metacarpophalangeal joint (MCPJ) flexion contracture by combining palmar segmental aponeurectomy with Z-plasty skin closure. The primary objective of this study was to assess range of motion of the operated ray after the procedure. The secondary objectives were to assess the complication rate and to determine the recurrence rate after at least 1 year.
Palmar segmental aponeurectomy with Z-plasty closure may provide the advantages of aponeurectomy while decreasing the surgical risk and recurrence rate.
A retrospective study was conducted in 16 patients with predominant MCPJ flexion contracture due to a well-defined palmar fascial cord. Anaesthesia was loco-regional. The Z-plasty design involved a longitudinal incision along the palmar cord with an oblique incision at each end at a 60° angle to the longitudinal incision. The length of the aponeurectomy was about 1.5cm, to allow full MCPJ extension.
In all, the 16 patients-13 males and 3 females-had 17 segmental palmar aponeurectomy procedures with Z-plasty closure. Mean operative time was 18minutes. Before surgery, mean loss of extension was 47° at the MCP joint and 15° at the corresponding proximal interphalangeal joint (PIPJ). Immediately after surgery, a 97% improvement in MCPJ extension was noted, leaving a mean extension deficit of 1.25°. Mean follow-up was 18.9 months. No complications occurred. Two patients experienced a recurrence.
Segmental palmar aponeurectomy as described by Moermans in 1991 improves extension similarly to extensive aponeurectomy but has a lower complication rate. Z-plasty provides good exposure of the pedicles and takes advantage of the greater pliability of the skin on either side of the cord to lengthen the skin by 75%, thereby limiting the risk of the complications seen with needle aponeurotomy. Segmental palmar aponeurectomy with Z-plasty has a role in the management of Dupuytren\'s disease with flexion contracture predominantly involving the MCPJ.
