UNASSIGNED: This study reports on outcomes of the flexor digitorum superficialis tendon transfer from the ring finger in @entity6276 . We included 22 @entity1 with 27 involved hands: 16 @entity1605 and five Type IIIA treated by transfer and six non-operated @entity1605 . The outcomes were assessed by range of motion, strength, sensibility, joint stability and @entity1 /parent satisfaction. Compared with normative data, the range of motion was diminished in all @entity1 groups. Opposition strength in operated @entity1605 was significantly better than in non-operated thumbs. Grip strength, pinch strength, tripod strength and key pinch strength were approximately 50% of normal in @entity1605 and 35% in Type IIIA thumbs. Metacarpophalangeal joint stability was restored in all operated @entity1605 and in 40% of Type IIIA thumbs. We conclude that the flexor digitorum superficialis tendon transfer of the ring finger is a good functioning opponensplasty in both @entity16337 . The transfer provides excellent stability of the metacarpophalangeal joint in @entity1605 . LEVEL OF EVIDENCE: Level IV.
