Successful Surgical Repair of Central Slip Rupture in Finger Extensor Tendon

The aim of the present study was to develop a novel effective surgical method to repair boutonniere deformity resulting from central slip rupture of finger extensor tendon. Currently, there are not standard methods available to treat boutonniere deformity. Patients and Methods: In the current study, 8 patients with boutonniere deformity on the left hand were included. All patients had a central slip rupture of the ring fingers. Autologous palmaris longus tendon was used to surgically repair the central slip rupture. Results: We successfully used the autologous palmaris longus tendons in the effective treatment of central slip rupture of the ring fingers resulting in boutonniere deformity on the left hands. Conclusion: To our knowledge, our study was the first illustration for a successful surgical repair of boutonniere deformity which resulted from central slip rupture, using autologous palmaris longus tendon. This method provides an alternative approach for the effective treatment of boutonniere deformity.
