Tendon surgery is unique because it should ensure tendon gliding after surgery. Tendon surgery now can be performed under local anesthesia without tourniquet, by injecting epinephrine mixed with lidocaine, to achieve vasoconstriction in the area of surgery. This method allows the tendon to move actively during surgery to test tendon function intraoperatively and to ensure the tendon is properly...

BACKGROUND Adhesion formation limits functional recovery after flexor tendon repair. Various growth factors have been implicated in the adhesion scar process. Early growth response factor-1 (EGR-1), a transcription factor associated with synthesis of a variety of key fibrotic growth factors and expression of extracellular matrix genes, has never been identified in a tendon repair model. METHO...

BACKGROUND Acute traumatic tendon injuries of the hand and wrist are commonly encountered in the emergency department. Despite the frequency, few studies have examined the true incidence of acute traumatic tendon injuries in the hand and wrist or compared the incidences of both extensor and flexor tendon injuries. METHODS We performed a retrospective population-based cohort study of all acute...

A 20-year-old man suffered a closed rupture of both flexor tendons in the middle finger while playing rugby. Primary repair of the flexor digitorum profundus and excision of the flexor digitorum superficialis was performed. At follow up he reported a Disabilities of the Arm, Shoulder and Hand score of 0 and unrestricted return to activities.

The excursion resistance between the tendon and pulley is an important factor contributing to the limitation of function after surgery to the hand. The administration of hyaluronic acid (HA) in the early rehabilitation after tendon grafting may help to prevent adhesions. We evaluated changes in the excursion resistance between potential sources of flexor tendon grafts and the annular pulley in ...

tendon never restores the complete biological and mechanical properties after healing. bone marrow and recently adipose tissue have been used as the sources of mesenchymal stem cells, which have been proven to enhance tendon healing. stromal vascular fraction (svf), derived from adipose tissue by an enzymatic digestion, represents an alternative source of multipotent cells, which undergo differ...

BACKGROUND Wide-awake hand surgery is useful for tendon reconstruction because surgeons can observe the actual movement of the reconstructed tendons during the surgery. We hypothesized that accurate ultrasound-guided injection of local anesthetics into the sensory nerves contributes to reliable analgesia with a relatively small amount of anesthetic. METHODS We enrolled 8 patients who underwen...

Introduction. This study was designed to investigate the influence of the amount of suture material on the formation of peritendinous adhesions of intrasynovial flexor tendon repairs. Materials and Methods. In 14 rabbits, the flexor tendons of the third and the fourth digit of the right hind leg were cut and repaired using a 2- or 4-strand core suture technique. The repaired tendons were harves...

OBJECTIVE To demonstrate the role of sonography in depicting periarticular changes in juvenile systemic lupus erythematosus (SLE) and to find out whether certain tendons in juvenile SLE patients were different from those of healthy controls. METHODS Thirty juvenile SLE patients (27 female, 3 male) were recruited for this study. Sonographic evaluations were performed in the knee, ankle, elbow,...
