objective: tendon never returns to its complete biological and mechanical properties after repair. bone marrow and, recently, adipose tissue have been used as sources of mesenchymal stem cells which have been proven to enhance tendon healing. in the present study, we compared the effects of allotransplantation of bone marrow derived mesenchymal stromal cells (bmscs) and adipose derived stromal ...

BACKGROUND The aim was to investigate the presence of feeding vessels in or in close proximity to extensor and flexor tendon sheaths at the wrists level and in finger flexor tendon sheaths in healthy controls, using 3D ultrasound (US), which may cause pitfalls, in order to ensure correct interpretation of Doppler signals when diagnosing tenosynovitis. METHOD Forty healthy participants (20 wom...

The unloaded human finger with a taut deep flexor functions as a bi-articular chain. because the angulations of the distal two joints are mechanically coupled. In this chain two flexors exist: the superficial and deep flexor. However, for elementary control of the unloaded finger. only one flexor is required. This puts forward the question of which flexor is most suited for unloaded finger cont...

Dynamic high-resolution ultrasonography findings obtained in 34 extreme rock climbers with finger injuries were compared with those in 20 healthy volunteers. Thicknesses of the flexor tendon and A-2 flexor tendon pulley system were measured at the base of the proximal phalanx. The distance between the tendon and phalanx was evaluated with the finger in extension and in forced flexion as a measu...

BACKGROUND Our aim was to summarize the treatment of degloving injury involving multiple fingers using combined abdominal superficial fascial flap, dorsalis pedis flap, dorsal toe flap, and toe-web flap. PATIENTS AND METHODS Each degloved finger was debrided under microscopic guidance and embedded in the superficial layer of the abdominal fascia. The abdominal skin was sutured to the skin on ...

Intratendinous ruptures of a flexor digitorum profundus tendon are rare in patients who do not have rheumatoid arthritis. A case of a patient with no history of autoimmune disease who suffered a traumatic rupture of the flexor digitorum profundus tendon to the ring finger in the mid-palm is reported.

The aim of this study was to evaluate the regenerative effect of platelets rich plasma PRP on tendon healing in donkeys. Eight adult donkeys from both sexes were used. The age range from 2-4 years and weighting 150-180 kg. The animals divided into two groups control and treatment group each group consists of four animals. The donkeys in both groups were given deep narcosis with 10% chloral hydr...

numerous causes are reported for ulnar nerve compression at the wrist, known as guyon's tunnel syndrome. in the present article, a patient with guyon's tunnel syndrome during pregnancy concomitant with an anomaly of ulnar nerve is described. a 29-year-old iranian woman presented with clinical features of guyon's tunnel syndrome (pain and paresthesia in the fifth finger of the left hand and atro...
