Early mobilisation after primary flexor tendon repair in 152 fingers (excluding zone II) and in 60 thumbs. "France Ouest Main Service".

The results of classical treatment (suture plus immobilisation) and of Kleinert's technique (suture under magnification with early semipassive movement), were compared in 290 primary flexor tendon repairs. The site of injury and the nature of associated injuries were the major prognostic factors. Kleinert's rehabilitation program was of particular value when a large range of movement was needed in simple lesions of zones III and IV. When tendon rupture must be avoided and preservation of strength is more important than achieving a full range of movement, immobilisation after an atraumatic suture is preferred.
