Basic science and clinical investigation have advanced significantly the treatment and the outcome following intrasynovial flexor tendon repair and rehabilitation and reconstruction over the past 30 years. The application of modern multistrand suture repair techniques as well as postoperative rehabilitation protocols emphasizing the application of intrasynovial repair site excursion has led to ...

The intrasynovial flexor tendons of the hand are critical for normal hand function. Injury to these tendons can result in absent finger flexion, and a subsequent loss of overall hand function. The surgical techniques used to repair these tendons have improved in the past few decades, as have the postoperative rehabilitation protocols. In spite of these advances, intrasynovial flexor tendon repa...

  Abstract   Background: The pathophysiology of carpal tunnel syndrome is associated with   increased intracarpal canal pressure. Recently, palmaris longus has been introduced   as an independent risk factor for the development of carpal tunnel syndrome. The   purpose of this study was to assess the association of carpal tunnel syndrome with   the presence of palmaris longus tendon and function...

The purpose of this study is to evaluate the advantages of an early active motion rehabilitation protocol after flexor tendon repair of the hand with the Teno Fix system. Patients with Zone II flexor tendon lacerations repaired with the Teno Fix system will undergo a rigorous early active motion protocol developed at the New York Orthopedic Hospital, starting post-op day 3. Each patient will be...

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...

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...

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...
