Abstract:
Objective To discuss the treatment and clinical efficacy of repair of soft tissue and nerve defect of thumb with island flap of first dorsal metacarpal artery based on the first dorsal metacarpal artery carrying dorsal branch graft of digital proper nerve.Methods The skin and nerve defect in 14 thumbs were repaired by dorsal island flap of index fingers based on the first dorsal metacarpal artery carrying dorsal branch graft of digital proper nerve.The size of skin defect ranged from 52 mm × 32 mm to 10 mm × 8 mm.The length of the nerve defect ranged from 9 mm to 22 mm.Results The average followup was 6-35 months.All 14 flaps survived with satisfactory appearance and function.The injured side of thumb pulp sensation recovered S3 + and the injured two-point discrimination ranged from 4 mm to 7 mm.No scar contracture or sensory dysfunction complication were observed in the donor sites.Conclusions The repair of soft tissue and nerve defect of thumb with dorsal island flap of index finger based on the first dorsal metacarpal artery carrying dorsal branch graft of digital proper nerve is recommendable,since it can obtain satisfactory clinical efficacy and be easily and conveniently oerformed.
