The wide-awake approach to flexor tendon repair has decreased our rupture and tenolysis rates, and permitted us to get consistently good results in cooperative patients. We no longer perform flexor tendon repair with the tourniquet, sedation and muscle paralysis of general or block (Bier or axillary) anesthesia. Injection of only lidocaine with epinephrine wherever incisions will be made in the...

OBJECTIVES We evaluated tendon reconstruction with one-stage tendon grafting in flexor tendon injuries in which primary repair was not considered because of delay in treatment or of inappropriate circumstances on the part of the wound and the patient. METHODS Thirty-seven patients (29 males, 8 females; mean age 20.5 years; range 4 to 52 years) underwent single-stage flexor tendoplasty involvi...

The functional morphology and evolution of the superficial forearm flexor, the palmaris longus, have long fascinated kinesiologists, physical anthropologists and anatomists alike. The anomalies, agenesis, variations and polymorphic presentation of the muscle, coupled with its biomechanical role in the performance of flexion and supination through distal articulations in the upper limb, have for...

Traumatic musculotendinous junction avulsions are rare injuries except in avulsion amputations. They pose a significant challenge to the treating surgeon. We present a 24-year-old male who sustained an open musculotendinous avulsion of the flexor pollicis longus tendon. He was treated with primary tendon transfer using the flexor digitorum superficialis of ring finger, in flexor zone 3. The fun...

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...

Although inflammatory activation of cytokines have been analyzed in various tissues, there have only been a few and as-yet-inconclusive studies on cytokines in equine tendons. In this study, the localizations of 4 cytokines (IL-1alpha, IL-1beta, TNFalpha and IFNgamma) in tendinocytes of the equine superficial digital flexor tendon (SDFT) were analyzed by the use of an immunohistochemical method...

The equine superficial digital flexor tendon (SDFT) is a frequently injured structure that is functionally and clinically equivalent to the human Achilles tendon (AT). Both act as critical energy-storage systems during high-speed locomotion and can accumulate exercise- and age-related microdamage that predisposes to rupture during normal activity. Significant advances in understanding of the bi...

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...
