We report on a rare case of fibroma of tendon sheath causing triggering of the right middle finger in an 86-year-old woman. Magnetic resonance imaging revealed a lesion attached to the flexor tendon sheath. Surgical excision was curative. Introduction Trigger finger is most frequently caused by stenosing tenosynovitis of flexor tendons in elderly patients. Trigger finger caused by a neoplastic ...

We describe a case of an 8-year-old boy who developed a combined motor and sensory neuropathy of the distal ulnar nerve, after sustaining a superficial injury to the right flexor carpi ulnaris tendon at the level of the distal wrist crease. Guyon's canal syndrome is a very rare entity during childhood. We have noted only one prior description of this syndrome in the pediatric age group in a rev...

The posterior compartment of leg is the largest but it diminishes markedly as it approaches the ankle. Flexor digitorum longus is thin and pointed proximally and gradually widens as it descends in the posterior compartment of leg. It arises from the posterior surface of the tibia medial to tibialis posterior from just below the soleal line to within seven or eight cm of the distal end of bone; ...

The presence of accessory tendons in the foot and ankle needs to be recognized, given that depending on their location, they may cause disorders relating either to pain processes or to handling of the surgical findings. We describe the presence of an accessory flexor tendon of the toes, seen in surgical exposure for transferring the long flexor tendon of the hallux to the calcaneus, due to the ...

Background: Tendon grafting is mostly required to repair an injury to flexor tendon and due to the importance of this tendon; it needs methods to speed up the re-vitality of the tendon allograft. OBJECTIVES: The aim was to investigate the efficacy of the mesenchymal cells and platelet rich plasma on the hydroxyproline content of frozen allograft tendons after grafting in lamb. METHODS: In this ...

Sarcomere number change was investigated in an animal model of tendon transfer. In 9 adult New Zealand white rabbits, the flexor digitorum longus muscle was cut distally and transferred and woven into the tibialis anterior tendon. Ankles were then immobilized for 3 weeks in 75 degrees flexion. Transferred flexor digitorum longus muscles were harvested and complete architectural analysis was per...

Tuberculous infection of the hand is a rare form of extrapulmonary tuberculosis that, left untreated, can cause serious joint and tendon damage. We report the case of a 65-year-old male patient who presented with an insidious flexor weakness of the fifth finger but without any history of trauma. Magnetic resonance imaging revealed a partial tear of the fifth finger flexor tendon with a fluid co...

Introduction Accessory flexor muscles in the forearm were first reported by Gantzer in 1813 [1]. These small accessory muscles typically arise from the medial arm and forearm [2] and the deep surface of the flexor digitorum superficialis [3]. Gantzer muscles insert via thin tendons into the tendon of the flexor pollicis longus, digitorum superficialis, or flexor digitorum profundus [2–4]. Here,...

The anterior interosseous nerve syndrome involves paralysis of the flexor pollicis longus, flexor digitorum profundus of the index and long fingers, and the pronator quadratus. We have encountered 33 cases of an incomplete syndrome in which only the flexor pollicis longus or the flexor digitorum profundus of the index finger is either paretic or paralyzed. This entity must be distinguished from...

The long-term results of the key grip procedure (tenodesis of the flexor pollicis longus tendon to the radius, release of the A1 pulley, and percutaneous pin fixation of the interphalangeal joint of the thumb) were evaluated in 10 tetraplegic patients. Seven patients also had tenodesis of the extensor pollicis longus and brevis tendons to prevent flexion at the metacarpophalangeal (MP) joint. P...
