Experience with the pedicled latissimus dorsi flap for finger reconstruction.

The pedicled latissimus dorsi flap was used for the reconstruction of finger function in 12 patients with severely disabled hands. The fascial origin of the muscle was sutured directly to finger flexors in 6 patients, and to extensors in the other 6 patients in the forearm without severing the neurovascular pedicle. Voluntary contraction of the muscle was obtained in all patients. Useful tendon gliding was achieved in 6 patients, thereby providing total active motion of fingers of >100 degrees. In the remaining 6 patients, however, several problems such as stiff finger joints prevented appropriate tendon gliding, resulting in total active motion of <60 degrees. When these problems are overcome, the pedicled latissimus dorsi muscle can yield satisfactory excursion for extrinsic tendons of the fingers. In contrast to free muscle transplantation, early and predictable recovery of function can be obtained using this particular technique without any risk of denervation of the muscle.
