Biomechanical study comparing Pulvertaft suture to step-cut suture.

Tendon grafts are a component of the therapeutic arsenal for managing chronic flexor tendons injuries in the hand, especially during two-stage Hunter reconstruction. The purpose of this anatomical study was to compare the strength of the Pulvertaft weave versus the step-cut suture used for flexor tendon reconstruction to determine their role in early active mobilization. We performed a biomechanical study with cadaver specimens.

Cubital tunnel syndrome: comparative results of a multicenter study of 4 surgical techniques with a mean follow-up of 92 months.

Background: Cubital tunnel syndrome is the second most frequent entrapment syndrome. Physiopathology is mixed, and treatment options are multiple, none having yet proved superior efficacy.

Objectives: The present retrospective multicenter study compared results and rates of complications and recurrence between the 4 main cubital tunnel syndrome treatments, to identify trends and optimize outcome.

[Neurotization of the deep branch of ulnar nerve and the thenar branch of median nerve with the pronator quadratus branch of anterior interosseous nerve by end-to-side transfer. An anatomic study].

Proximal or middle lesions of median or ulnar nerves are responsible for a great loss of hand motor function. Neurotization of either deep ulnar branch of ulnar nerve (DBUN) or recurrent (thenar) branch of median nerve (RBMN) with the nerve to quadratus pronator (NPQ) from the anterior interosseous nerve (AION) could reduce length of axonal growth and therefore the reinnervation lead-time of hand intrinsic muscles. We studied the anatomy of these three nerves, to help surgeon choosing his (her) technique and approach.

[Functional results of homodigital pedicle island flaps for finger-pulp defects. Evaluation of 15 cases].

Objectives: Fingertip amputations are very common. The aim of the treatment is to restore the sensibility of the finger pulp, with adequate pulp padding. The homodigital pedicle island flaps are used in zone 2 or 3 of Allen's classification.
