Dear Sir, A 37-year-old right-handed woman presented with a 2 week history of loss of flexion, pain and swelling of her right little finger. She had been diagnosed with trigger finger at another hospital and had been given seven flexor sheath injections of 20 mg of triamcinolone ace-tonide and 1 lignocaine around the A1 pulley over a 14 month period. About 2 months after the last injection, while trying to move the headrest of her car seat, the woman experienced painful snapping in her right little finger and lost flexion of the distal interphalangeal (DIP) joint. A rupture of the flexor digitorum profundus (FDP) was suspected and the patient was referred to our hospital.
