Restoration of Sensibility Following Reconstruction of Soft Tissue Defect of Thumb with the First Dorsal Metacarpal Artery Island Flap

Introduction: Thumb injuries constitute a challenge for the plastic surgeon because loss of its function compromises entire upper limb. If there is soft tissue defect in thumb where tendons, joints, or bones exposed, it requires stable vascularized flap reconstruction preferably with local regional flap. The First Dorsal Metacarpal Artery (FDMA) island from dorsum index finger an option reconstructing such defect. Objectives: To assess quality sensitivity at site following FDMA Materials and Methods: A prospective observational study was conducted July 2012 to June 2013 among 31 patients admitted exposure tendon, bone, joint pulp were treated innervated Recovery sensation evaluated by static-2PD test. Results: Out 28 male 3 female ratio 9:1. mean age 26.2±8.8 years. large number patient manual worker (construction worker, mechanic). Most them sustained injury their dominant (61%). common cause electric burn (78%) rest due machinery injury. Average s-2PD over area 9.1 mm (range, 8-12 mm) compared 7.4 7-11 donor opposite 5.5 3-9 corresponding thumb. 1.4 (19.2%). Every satisfied outcome. Conclusion: Restoration sensibility quite satisfactory after first dorsal metacarpal artery JAFMC Bangladesh. Vol 18, No 1 (June) 2022: 34-38
