Abstract
Introduction: The thumb has a part in roughly 40% of hand capacity; traumatic loss brings about significant disability. A perfect reconstructed thumb would have satisfactory length, a sensate, non-tender tip, have security and be situated to meet alternate digits, with a sufficient first web space. Our objectives are study of different modalities of distal thumb reconstruction and evaluation of each modality regarding its sensation, stability, length, mobility, position, and pain-free function. Patients and methods: This study was conducted between January 2014 and January 2016 on 38 patients. These patients were presented with partial thumb amputation extends from the interphalangeal joint to the thumb tip secondary to trauma. The patients divided into four groups according to the method of reconstruction. assessment included measuring the static and moving 2 point discrimination, Semmes-Weinstien monofilament test, the grip and pinch strength, Kapandji score and stereognosis Results: It was found that there were statistical significant differences between affected and unaffected groups as regards static and moving 2 point discrimination, grip strength except V-Y flap group, Pinch strength except for pulp to lateral in patients underwent V-Y flap, stereognosis except cross finger flap group, Kapandji score Conclusion: The mean grip and pinch strength were lower in affected hands compared with the unaffected sides. Use of sensate homodigital flaps (Moberg and V-Y advancement) gives better results than heterodigital flaps (FDMA and Cross finger)
