Abstract:
The purpose of this study is to introduce a new method for fingertip coverage for cases of soft tissue only defects and finger tip amputations including bone. 86 lingers in 67 patients haute undergone coverage with a large rotation flap based on digital artery and nerve and Z-plashy after fingertip amputation or finger pulp avulsion from October 1991 to December 1995. There were 53 thumbs, 12 index fingers, 5 long fingers, 3 ring fingers and 13 little fingers. All injured fingers had exposure of the distal phalanx bone. A large volar flap based on either the radial or ulnar aspect including both digital neurovascular bundles was elevated just abode the pulleys and flexor tendon sheath after longitudinal incision along the lateral border of the digit. Then a large Z-plasty was performed at the MP joint crease to release the tension. The volar flap was easily rotated to cover the fingertip and was sutured with slight flexion of the interphalangeal joints. All fingertip defects healed completely. These flaps successfully covered the fingertip, and up 2/3 of the distal phalanx on the volar or lateral aspect. Sensation returned to normal and fingers could be fully extended within 3 months of surgery. All patients only required a single operation for complete fingertip coverage and did not require bony shortening. We conclude that this large rotation, axial pattern, neurovascular flap and Z-plasty provided a durable, completely sensate, well vascularized coverage fort the fingertip with minimal discomfort for the patient.
