The injection of contrast material into the navicular bursa, accompanied by a subsequent radiographic examination, provides new and relevant information about pathologic damage to the navicular flexor fibrocartilage and the deep digital flexor tendon. It is the only diagnostic method currently being used that can determine whether adhesions have occurred between the navicular bone and deep flex...

INTRODUCTION: A tendon graft is indicated when a flexor tendon repair fails, or when tendon rupture or tendon transfer requires prolongation of the muscle-tendon unit. The effect of hyaluronic acid (HA) on flexor tendon repair has been investigated in many animal and clinical studies. Exogenously applied HA may prevent adhesion formation between the flexor tendon and surrounding tissue followin...

Chondroma of soft tissue is rare. We report a patient in whom a chondroma occurred within the flexor tendon sheath of the index finger. Magnetic resonance imaging showed the extent of the tumor, which wrapped around flexor tendons within the sheath, but did not invade either tendons or sheath. Total excision was done with preservation of the flexors and flexor tendon sheath. After the operation...

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...
