Technique for Central Slip Reconstruction for Chronic Boutonniere Deformity.

There is currently no consensus on which existing treatment for chronic Boutonniere deformity is most effective. We describe a method of central slip reconstruction with an autologous "V" shaped tendon graft folded on itself through a bone tunnel for the treatment of Boutonniere deformity. All 3 patients healed well with an average active range of motion of the distal interphalangeal joint 10 to 70 degrees, proximal interphalangeal joint 15 to 90 degrees, and metacarpophalangeal joint 0 to 90 degrees with a follow-up duration between 4 years and 5 years. This is a straightforward technique that can be performed in patients with chronic, post-traumatic and flexible Boutonniere deformity.
