Summary

Trigger finger is a pathology of the flexor tendons caused by inflammation of the tendon or its sheath, leading to pain, nodules, fibrosis, and limited mobility. Surgical treatment aims to release the space at the level of the A1 pulley, either through longitudinal opening (the standard technique, but associated with recurrence rates of approximately 7.7%) or through complete resection, an emerging approach that may reduce recurrences and the need for reoperations. However, comparative data remain limited, justifying further investigation. This project therefore aims to compare these two surgical techniques to determine which one results in the lowest recurrence rate and to assess their functional outcomes (pain, range of motion). The primary hypothesis is that A1 pulley resection reduces recurrences after one year, while the secondary hypothesis is that there is no significant difference in postoperative pain or mobility.

Conditions

  • Trigger Digit
  • Trigger Finger

Interventions

PROCEDURE

Longitudinal incision

A longitudinal incision of the A1 pulley performed to open the pulley, thereby reducing the pressure on the inflamed tendon and facilitating its gliding during finger movements.

PROCEDURE

Complete resection

Fully removing the pulley in order to eliminate friction between the tendon and its fibrous band
