METHODS: We report a case of 48-year-old surgeon who sustained a trauma to her left middle finger. The patient presented three months after injury with complaints of pain and decreased range of motion of involved digit. Patient was treated conservatively and after failure of conservative treatment surgical intervention was done with complete tendon excision and capsulotomy of Proximal interphalangeal joint. Patient retained full range of motion and pain subsided.
CONCLUSIONS: Isolated closed avulsions or rupture of the FDS tendon is a challenging entity in hand surgery in diagnosis and treatment. Nonsurgical treatment with splinting and physiotherapy might help to prevent flexion deformity. The surgical treatment include tenolysis, flexor digitorum superficialis tendon excision, and in selected patients capsulotomies of involved joints.
CONCLUSIONS: A review of the literature identified only few cases of closed avulsion of FDS tendons nonpathologically. Early diagnosis and intervention can prevent sequel of flexion contracture.
