title: [Surgical correction of fifth finger permanent abduction by tenodesis. Preliminary cadaver study].
abstract: Permanent abduction of the little finger can be responsible for daily embarrassment in patients with an ulnar nerve palsy. To correct this deformity, active transfers are usually performed utilising the extensor tendons of the hand. Because of the anatomical variability of the extensor system of the hand, these active transfers can be responsible for postoperative loss of full extension of the little finger. Analysis of the orientation of the forces generated by these transfers shows that they are only weak adductors. A surgical technique using tenodesis is proposed in this preliminary study. This tenodesis has the objective of increasing the adductive forces on the little finger without an extensor tendon transfer. The advantages and disadvantages of this technique are discussed. A clinical evaluation will be undertaken at a later date to confirm the reliability of this technique.
