Flexor Digitorum Superficialis Tendon Transfer for Intrinsic ReplacementLong-term results and the effect on donor fingersFrom the All Africa Leprosy and Rehabilitation Training Centre, Addis Ababa, Ethiopia Correspondence: J. W. Brandsma, National Institute for Research and Postgraduate Education in Physiotherapy, Postbus 1161, 3800 BD Amersfoort, the Netherlands. At the time of the study both authors were employed in the Department of Surgery and Rehabilitation of the All Africa Leprosy and Rehabilitation Training Centre, PO Box 165, Addis Ababa, Ethiopia. This study is a review of 127 hands in 100 patients in whom one or two FDS tendons were used to correct claw-hand deformity and/or loss of opposition of the thumb. In lumbrical replacement the results were graded as excellent in 16 hands (21%) and good in 43 hands (57%). For opponensplasty the results were excellent in 26 hands (32%) and good in 42 hands (51%). Possible defects that can develop in the donor finger are: swan-neck deformity, flexion posture of the DIP joint, not as part of the swan-neck deformity, check-rein deformity or flexion contracture, and insufficient finger flexion. Of the 158 fingers swan-neck deformity was seen in 15%, DIP flexion in 29%, check-rein deformity in 26% and insufficient finger flexion in 18%. The latter occurred with another defect. In 48 fingers (30%) no defects were observed.
