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 ...

Spontaneous flexor tendon ruptures are rare. Thirteen patients who had spontaneous intratendinous rupture of the flexor digitorum profundus tendon are described. Twelve of the ruptures occurred in zone III at the level of the lumbrical origin, and one occurred in zone II distal to the A2 pulley. All patients were involved in an activity that required flexion against resistance. Time from injury...

OBJECTIVE Dactylitis is a hallmark of psoriatic arthritis (PsA) where flexor tenosynovitis is common. This study explored the microanatomical basis of dactylitis using high-resolution MRI (hrMRI) to visualise the small entheses around the digits. METHODS Twelve patients with psoriatic dactylitis (4 fingers, 8 toes), and 10 healthy volunteers (6 fingers, 4 toes) had hrMRI of the digits using a...

  Background: Peritendinous adhesions after repairing an injury to the digital flexor tendons are a major problem in hand surgery. Non-steroidal anti-inflammatory drug therapy may affect tendon healing and the development of peritendinous adhesions. The aim of this study was to evaluate ibuprofen effect in patients function after flexor tendon surgical repair.   Method: Thirty-five patients, wh...

Neglected Achilles Tendon Ruptures are commonly seen by orthopaedic surgeons. In cases resistant to conservative treatment, a variety of surgical procedures have been utilized in the past. The senior -surgeon at our institution has utilized a technique -employing two turndown fascia flaps fashioned from the proximal Achilles tendon augmented by a tenomyodesis of the flexor hallucis longus and p...

A study has been made of the ultrastructural organization of the collagen fibrils and elastic fibres in tendons and ligaments from horses of ages ranging from 2 months premature to 19 years. Diameter distributions of the collagen fibrils in the common digital extensor tendon, the super­ ficial flexor tendon and the suspensory ligament are unimodal in the foetal tissue and a t birth, and a t the...

BACKGROUND Functional restoration is the major concern after flexor tendon reconstruction in the hand. The purpose of the present study was to investigate the effects of modifying the surface of extrasynovial tendon autografts with carbodiimide-derivatized synovial fluid with gelatin (cd-SF-G) on functional outcomes of flexor tendon reconstruction using a canine model. METHODS The second and ...
