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 & Aims: Forward head posture deformity is a disorder in head weight balance condition leading to some alterations in cervical muscles, strength. This research aimed to determine the strength of deep and superficial cervical flexor muscles in female students with forward head posture compared to the normal group. Methods: From the total of 724 female students in Shahid Bahonar Univers...

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...

PURPOSE To evaluate the condition of the tendons and neurovascular bundles after percutaneous release for trigger finger of the middle, ring, and little fingers. METHODS 30 women and 13 men aged 20 to 55 (mean, 40) years underwent percutaneous release of the A1 pulley using a 18-gauge needle for 43 trigger fingers of the middle, ring, or little finger unresponsive to conservative treatment. 1...

Some tendons, such as the human Achilles and equine superficial digital flexor tendon (SDFT), act as energy stores, stretching and recoiling to increase efficiency during locomotion. Our previous observations of rotation in response to applied strain in SDFT fascicles suggest a helical structure, which may provide energy-storing tendons with a greater ability to extend and recoil efficiently. D...

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...

The aim of this study was to determine the course of the median nerve and its adjacent structures in the carpal canals of 8 healthy dogs by using high-frequency transducers. Before performing ultrasonography, the transverse and posteroanterior diameters as well as the perimeter of the carpus were measured at just proximal to the side of the carpal pad. The anatomical structures were then determ...
