[Value of pulp recession in inveterate hook fingers. Techniques/indications].

The aim of this operation is to preserve the sensitivity whenever when a finger has to be amputated. We have reviewed 9 patients operated according to this technique, out of 14 patients for whom an amputation or a shortening arthrodesis was discussed. The results of pulp recession were most encouraging. The incision were located on both sides of the finger and distant from the ungueal matrix. The dorsal skin was elevated in the sub-periosteal plane. Resection of the necessary amount of 2nd phalanx to obtain an extended finger was performed. An osteosynthesis with pins is preferred for a duration of 6 weeks. This operation can be performed for very stiff finger, hooked fingers or dystrophic fingers with a good pulp. In extreme cases of shortening, the nail with its bed ar sacrificed, and the entire pulp is used to cover the distal stump. This principal of pulp recession has been used in two other cases in emergency surgery. The postoperative was marked by finger swelling and some pain of the distal sutured skin. Overall the results were satisfactory and patients were very satisfied to keep their finger, which would otherwise have been doomed.
