Abstract
- Transposition of the second or fifth finger ray following amputation of the middle or ring finger is an uncommon recenstructive procedure of the hand and the importance of which often is overlooked. Following amputation of either central digit, grip is usually weakened, especially when the middle finger is involved, because three point chuck pinch is compromised. Small objects tend to fall from the grasp through the space left by the missing digit. Transposition of either the second or fifth ray closes the gap created by miasing digit, and it restores the function of grasp and grip, furth improves apperance of the hand. The Authers have treated 10 cases of hands, missing central finger rays from 1977 to 1980. In this series, there was a case of malrotation of transposed digit, a ease of malunion of the transpoesed digit and a case of malunion of the proximal phalanx of the transposed index. Concerning additional operation after ray transposition, there was a caae of adhesiolyais of flexor tendon, a case of Swanson Arthroplasty on the metacarpophalangeal joint of the transposed index finger and s case of extenaor plasty for reconstruction of the extensor power. The osteotomies healed promptly in 9 weeeks in Posner's fixation cases. Prehensian and esthetics of the hands were improved in all cases.
