The modified Stack procedure for central slip reconstruction: a case series

There are many surgical techniques for reconstruction of the divided or incompetent central slip. Most rely upon postoperative immobilisation to protect the repair. We present our experience using a distally based flexor digitorum superficialis slip to reconstruct the central slip and allow early mobilisation in five patients with intact preoperative intrinsic function. Post-treatment, a mean recovery of 65 degrees of active extension was achieved, albeit at the cost of a mean 22-degree loss of active flexion. We suggest this relatively easy technique provides a useful surgical option in the management of this difficult problem.
