Extensor pollicis longus dysfunction associated with non-united fracture of the trapezium.
نویسندگان
چکیده
A 26 year old man was referred to us with extensor pollicis longus dysfunction (EPL), and investigation revealed a fracture of the trapezium (left) and carpo-metacarpal joint dislocation of the thumb. Operative exploration revealed mechanical displacement of the tendon secondary to fracture dislocation of the trapezium as the cause for EPL dysfunction. The lesion was managed with an open reduction and screw fixation resulting in good functional outcome.

A simulating analysis of the effects of increased joint stiffness on muscle loading in a thumb
BACKGROUND The development of osteoarthritis (OA) in the hand results in increased joint stiffness, which in turn affects the grip strength. The goal of the present study is to theoretically analyze the muscle forces in a thumb in response to the increased joint stiffness. METHODS The thumb was modeled as a linkage system consisting of a trapezium, a metacarpal bone, a proximal and a distal p...
متن کاملRupture of the extensor pollicis longus tendon after Colles fracture.
During the period 1973-1986, 116 patients with rupture of the extensor pollicis longus tendon were operated upon. The lesions were categorised into three anatomical levels: proximal, intermediate and distal. Direct suture was performed for acute lesions; later reconstructive procedures were by means of tendon transfers or free tendon grafts.

○ Approach with care, especially with the branch of the dorsal sensory radial nerve, which is very close to the space between Abductor PollicisLongus and Extensor PollicisBrevis. ○ Freeing the base of the metacarpal is very importantin order to obtain a good view of the distal surface of the trapezium, because after an adequate resection of the base of the metacarpal and of the palmar beak it’s...
متن کاملRupture of the extensor pollicis longus tendon following dorsal entry flexible nailing of radial shaft fractures in children
INTRODUCTION Diaphyseal forearm fractures are common in children and adolescents. Intramedullary fixation with flexible nails has a high success rate. Complications related to the insertion of the radial nail include injury to the superficial branch of the radial nerve and rupture of the extensor pollicis longus (EPL) tendon. MATERIALS AND METHODS We report a series of nine patients who susta...
متن کاملMuscle moment arms in the first dorsal extensor compartment after radial malunion. A cadaver study.
BACKGROUND Functional loss is a common complication of the fractured distal part of the radius. The purpose of the present study was to determine if the moment arms of the first dorsal extensor compartment are altered by distal radial fracture malunion. We hypothesized that the moment arms of the abductor pollicis longus and extensor pollicis brevis are significantly affected by dorsal angulati...
