Abstract: Title of the Article Case report Fascia-lata graft for correction of Boutonniere deformity of left middle finger. Introduction Boutonniere deformity is characterized by flexion at proximal interphalangeal joint, hyper-extension at distal interphalangeal joint, resulting from dorsal disruption of the extensor at the proximal interphalangeal joint. Fixed deformity with contractures will result if neglected. Splints and exercises are tried and surgery is contemplated on supple joints, in those without response on conservative management. Aims To demonstrate our experience with Fascia lata tendon grafting for the correction of the deformity. Methodology 25 year old male computer operator had Post-traumatic Boutonniere deformity of Left Middle finger. Post physiotherapy with supple joints, proximal interphalangeal joint was fixed in extension with K-wire. Fascia-lata graft was used to bridge the extensor tendon defect. The volarly displaced Lateral bands were mobilized towards the reconstructed central tendon. Results Satisfactory functional recovery was obtained using Fascia-lata graft. Boutonnieres deformity, Fascia-lata tendon graft, proximal interphalangeal joint, base of middle Phalanx, Lateral bands, K-wire. Key Messages Fascia-lata is a useful source of Tendon graft and surgery with tendon graft enabled good functional recovery. Physiotherapy is needed to keep the joints supple before surgery and to regain mobility after surgery.
