Swan-Neck Correction by FDS Tenodesis and Dynamic Lateral Band Volar Relocation in the Setting of Cerebral Palsy

Abstract

While there are many proposed surgical treatment options for the correction of swan-neck deformities, none are perfect. We describe a partial flexor digitorum superficialis tenodesis that combines both a static volar plate with a dynamic oblique retinacular ligament vector reconstruction. This is performed through a single, short mid-lateral incision and requires no tendon grafts. The protected early active exercises are encouraged postoperatively, and our long-term results have been promising. The technique was designed for children with cerebral palsy, but the indications have since expanded. Level of Evidence: Level V (Therapeutic)
