Background To describe the clinical and magnetic resonance imaging findings of ganglion cysts with effusion in the flexor hallucis longus tendon sheath around the hallux to evaluate their origin. Methods Patients with recurrent or painful ganglion cysts around the hallux with effusion in the flexor hallucis longus tendon sheath who underwent surgical treatment at St. Vincent's Hospital from F...

The purpose of this research was to develop a tissue-engineered intrasynovial flexor tendon construct with the use of an acellularized flexor tendon scaffold repopulated with intrasynovial tendon cells. New Zealand white rabbit intrasynovial flexor tendons were acellularized by the following methods: high concentration NaCl + SDS, Trypsin/EDTA, Trypsin/EDTA + Triton X-100, Triton X-100, Triton ...

The carpal tunnel contains the median nerve, nine flexor tendons, two synovial bursae, and peritendinous subsynovial connective tissue (SSCT). Fibrosis of the SSCT is the most consistent pathological finding in patients with carpal tunnel syndrome. We investigated the anatomy and gliding characteristics of the flexor digitorum superficialis tendon and its adjacent SSCT with high-resolution ultr...

During the last 20 years there have been significant innovations in injury repair and aftercare for patients who sustain zone 2 flexor tendon injuries. Improvements in our understanding of the mechanisms of repair and the variables that impact the function of the repair site have resulted in outcome improvements. The purpose of this article is to review advances in flexor tendon surgery and to ...

BACKGROUND Wide-awake flexor tendon repair in tourniquet-free unsedated patients permits intraoperative Total Active Movement examination (iTAMe) of the freshly repaired flexor tendon. This technique has permitted the intraoperative observation of tendon repair gapping induced by active movement when the core suture is tied too loosely. The gap can be repaired intraoperatively to decrease posto...

Flexor digitorum profundus (FDP) tendon avulsion is a common injury in sports. This is secondary to forced extension against flexor digitorum profundus contraction. However, avulsion injury of the FDP tendon secondary to an enchondroma of the distal phalanx is extremely rare. There have only been three previous reports of such an occurrence. This report describes a fourth case of an avulsion in...

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...

BACKGROUND Carpal tunnel syndrome (CTS) describes a set of symptoms caused by compression of the median nerve in the wrist, which is the most common site of nerve compression in the upper limb. This syndrome is a primary source of pain and reduced function in these patients, and the cause is compression of the median nerve where it passes beneath the flexor retinaculum in the wrist. OBJECTIVE...
