[What's new in surgery of flexor tendons?].

After revealing tendon healing and the international classification adopted in 1980 for flexor tendon lesions, the author reviews the primary tendon repair procedures and the various postoperative mobilization protocols. The current tendency is towards early active mobilization with a protection orthosis. The various secondary surgical procedures are then critically discussed: secondary suture, tendon release, one-stage or two-stage tendon graft, total anterior tenoarthrolysis, tendon transfer, vascularized tendon graft, active tendon implants.
