A2 pulley integrity and the strength of flexor tendon repair: a biomechanical study in a chicken model.

Purpose: This study assesses the influence of A2 pulley integrity on the strength of the repair.

Method: Part 1- The flexor digitorum profundus (FDP) tendons of 72 Cobb chicken feet were severed and repaired in the region of the A2 pulley using a modified Kessler core suture and an epitendinous suture. The A2 pulley was either left intact, divided for 50% of its length, or divided in its entirety.
