Percutaneous needle aponeurotomy: complications and results

Recently French rheumatologists have repopularized fasciotomy using a percutaneous needle technique. This blind approach has been claimed to be plagued by numerous complications. We reviewed the charts of 211 patients treated consecutively on 261 hands and 311 fingers to assess the rate of postoperative complications. The first 100 patients were evaluated with a mean follow up of 3.2 years to assess the rate of recurrences and extension of the disease. In the whole group the mean age was 65 years and delay between onset and treatment was 6 years. Division of the cords were performed only in the palm in 165 cases, in the palm and finger in 111 and purely in the finger in 35. Complications were scarce without infection or tendon injury but one digital nerve was found injured during a second procedure. Postoperative gain was prominent at metacarpophalangeal joint level (79% versus 65% at interphalangeal level). The reoperation rate was 24%. In the group assessed at 3.2 years follow up, the recurrence rate was 58% and disease "activity" 69%. Fifty nine hands need further surgery. The ideal indication for this simple and reliable technique is an elderly patient with a bowing cord and predominant MP contracture.
