Most overuse tendinopathies are thought to be associated with repeated microstrain below the failure threshold, analogous to the fatigue failure that affects materials placed under repetitive loading. Investigating the progression of fatigue damage within tendons is therefore of critical importance. There are obvious challenges associated with the sourcing of human tendon samples for in vitro a...

conclusions the treatment of symptomatic ecu instability is still controversial, especially for acute dislocations. depending on the type of injury many surgical techniques have been proposed. combination of direct repair of the tendon’s subsheath and reinforcement with an extensor retinaculum graft is a reliable option. introduction dislocation/subluxation of the extensor carpi ulnaris (ecu) t...

We reviewed 11 patients who had been treated between January 1986 and June 1994 for severe foot injuries by tendon transfer with microvascular free flaps. Their mean age was 5.6 years (3 to 8). Five had simultaneous tendon transfer and a microvascular free flap and six had separate operations. The mean interval between the tendon transfer and the microvascular free flap was 5.8 months (2 to 15)...

Tendon injuries are an important problem in athletic horses and are probably caused by excessive loading of the tendons during demanding activities. As a first step towards understanding these injuries, the tendon loading was quantified during jump landings. Kinematics and ground reaction forces were collected from the leading and trailing forelimbs of 6 experienced jumping horses. Joint moment...

OBJECTIVE This pilot study compared the effectiveness of 3 postoperative rehabilitation protocols for patients with Zones V and VI extensor tendon lacerations. METHOD Twenty-seven patients were recruited from 3 sites and randomly assigned to 1 of 3 established treatment protocols: immobilization, early passive motion (EPM), and early active motion (EAM). Outcome measures were collected at 3, ...

This paper describes a new technique in the repair of the hand defect with digital extensor tendon injury. The anterolateral thigh flap with the thick femoral fascia has been used in the reconstruction of the composite defect of the dorsal hand, especially the defect of tendon. This technique requires short period of treatment and hence causes less damage to the donor site but shows a better re...

INTRODUCTION Although spontaneous extensor tendon rupture often occurs in association with rheumatoid arthritis, extensor tendon rupture associated with osteoarthritis of the distal radioulnar joint has been rarely reported. CASE PRESENTATION We present the case of a 74-year-old Asian woman with a fourth and fifth extensor tendon rupture caused by instability of the ulnar head associated with...

Background. Radial subluxation of the extensor communis tendons at the metacarpophalangeal (MCP) joints is a rarely reportedvinjury. These injuries have proved difficult to reproduce in cadaveric studies and have a low biomechanical likelihood of occurrence due to the ulnar direction of pull of the extensor communis tendons. It has been suggested that the juncturae tendinum may have a stabilisi...
