Operative treatment of the post-traumatic boutonnière deformity. A modification of the direct anatomical repair technique.
We report 20 cases of post-traumatic boutonnière deformity treated by a modification of the direct anatomical repair technique, particularly indicated in late cases which have complete passive motion. A swallow-tailed flap is excised from the fibrous tissue between the two ends of the central slip. The proximal one is then advanced up to the coaptation with the distal edge of the scarred capsular tissue at the insertion on the middle phalanx to which it is sutured in correct tension. Excellent results have been obtained in 72% of cases and good in 5.5%. The 16% of fair results are probably due to the fact that patients didn't use the splint post-operatively and didn't cooperative with physiotherapy.
