OBJECTIVE This study assessed the impact of keyboard angles (in terms of Pitch, Roll and Yaw) on tendon travel and wrist and finger joint kinematics for the flexor digitorum profundus and flexor digitorum superficialis.DESIGN. A repeated measures, laboratory study was conducted. Independent variables were three Pitch angles, three Roll angles, three Yaw angles, and three keyboard separation dis...

The wide-awake approach to hand surgery is performed with no sedation and no tourniquet. Only locally injected tumescent lidocaine and epinephrine are used for anesthesia and hemostasis. The confirmation that epinephrine hemostasis in the finger is safe1–5 has permitted the use of this technique, which has now become widespread in Canada. With exceptions that include hand surgery in small child...

Although the predominant function of all tendons is to transfer force from muscle to bone and position the limbs, some tendons additionally function as energy stores, reducing the energetic cost of locomotion. To maximise energy storage and return, energy-storing tendons need to be more extensible and elastic than tendons with a purely positional function. These properties are conferred in part...

Rock climbers' grip techniques may result in a variety of hand injuries. Minor injuries such as soft-tissue damage, flexor tendon strain, tendinitis or tenosynovitis, joint contractures, and carpal tunnel syndrome may be treated by a primary care physician. Patients who have pulley ruptures should be referred if there is any uncertainty about the diagnosis. Because of controversies regarding su...

This case report describes the intralesional application of autologous conditioned plasma (ACP) in seven horses as treatment of severe tendinitis of the superficial digital flexor tendon, deep digital flexor tendon, or desmitis of the inferior check ligament. Follow-up data of the horses revealed a positive outcome in 10 to 13 months post injury. All horses treated with ACP were either performi...

Many operations have been described to restore active opposition of the thumb, but all are dependent on the transplant of tendons and their rerouting to fulfil their new function. When there is no motor available for transplant-quite a common problem-the accepted procedure is to unite the first metacarpal bone to the second in the position of opposition. In 193 1 von Baeyer described a method o...
