Management of scar contractures of the hand using Z advancement rotation flap

Functional consequences of hand contractures may lead to extreme impairment in hand functions so repair of the contractures can solve the problems related to hand functions. Different forms of z plasties have widely been used for the release of scar contractures. In this study, a useful z plasty technique, z advancement rotation flap (ZAR) was adapted for the release of hand contractures in the way of using only local tissues. Fourteen consecutive patients who had hand contractures, were treated successfully with z advancement rotation flap technique. They suffered from hand contractures for at least one year which were localized in wep spaces, flexor surfaces of the digits, first wep space, palmar area and extensor surface of the hand. Contractures are all in mild severity, restricting some of the hand motions moderately. In all patients, hand contractures released completely and clinically normal joint motions were achieved, improving extension, flexion and abduction ranges of fingers without any difficulty. All advanced and rotated flaps healed uneventfully. No major complications appeared such as infection, hematoma, suture dehiscence, flap congestion or necrosis. When dealing with this technique for release of hand contractures, it may offer a versatile alternative to well known z-plasty methods used particularly for hand contractures.
