We treated 3 patients who had ruptured the flexor pollicis longus (FPL) tendon during infancy and which had not been repaired. A two-stage surgical procedure, using a silicone rod, was performed to reconstruct the tendon, and favorable thumb flexion was obtained. A favorable outcome was obtained, even if the gliding of the silicone rod had been poor after the first stage procedure. When the sca...

A rare case of closed complete rupture of the flexor hallucis longus tendon at its groove in the posterior process of the talus is reported in a soccer player who developed pseudarthrosis of the posterolateral tubercle of the talus after a Shepherd's fracture. Partial rupture or tenosynovitis of the flexor hallucis longus tendon at this level is well known in classical ballet dancers and soccer...

background laceration of the hand extensor tendons is common in the upper extremities, causing soft tissue trauma. these tendons, because of their superficial location and lying adjacent to bones, have a greater tendency to be injured than flexor tendons. objectives the aim of this study was to determine the results of primary repairs of lacerated extensor tendons of the fingers, with respect t...

BACKGROUND There is a paucity of data regarding molecular markers that identify the phenotype of the tendon cell. This study aims to quantify gene expression markers that distinguish between tendon fibroblasts and other mesenchymal cells which may be used to investigate tenogenesis. METHODS Expression levels for 12 genes representative of musculoskeletal tissues, including the proposed tendon...

We report a case of acute (24 h) double flexor tendon rupture of the little finger after a single injection of collagenase clostridium histolyticum into a palmar Dupuytren's contracture cord which caused metacarpophalangeal joint contracture. Tendon surgery was performed 48 h postinjury with primary repair and standard rehabilitation but it resulted in poor active flexion due to adhesions. Prev...

Hyperthermia (targeted core temperature: 38.5°C) reduces the time between gastrocnemius medialis stimulation and onset of plantar flexor force production in vivo. This reduction electromechanical delay is concomitant to an earlier motion muscle fascicle compared with thermoneutral environment. However, hyperthermia has no impact on duration transmission along aponeurosis tendon, thereby reflect...

Tendon adhesions are one of the most concerning complications after surgical repair of flexor tendon injury. Extracellular signal-regulated kinase (ERK) 2 plays crucial roles in fibroblast proliferation and collagen expression which contributes to the formation of tendon adhesions after flexor tendon surgery. Using a chicken model, we have examined the effects of a small interfering RNA (siRNA)...

A rare case of closed complete rupture of the flexor hallucis longus tendon with subsequent longitudinal tear of the flexor digitorum longus tendon is reported in a marathon runner. This is also a first case report of flexor hallucis longus transplant with cadaveric posterior tibial tendon allograft. Two minimal incisions distal and proximal to the malleolus allowed for tunneling with urethral ...

BACKGROUND Palmar region of metacarpus in the horses and donkeys is an important region because of its tendons and ligaments which contribute to stay apparatus. This study was done on forelimbs of 6 healthy Miniature donkeys to detect the tendons, ligaments and their accessories on the palmar surface of metacarpus in this animal. MATERIALS AND METHODS Based on that magnetic resonance imaging ...

A nonlinear elastic microstructural model is used to investigate the relationship between structure and function in energy-storing and positional tendons. The model is used to fit mechanical tension test data from the equine common digital extensor tendon (CDET) and superficial digital flexor tendon (SDFT), which are used as archetypes of positional and energy-storing tendons, respectively. The...
