BACKGROUND Barbed suture material offers the possibility of knotless flexor tendon repair, as suggested in an increasing number of biomechanical studies. There are currently two different absorbable barbed suture products available, V-Loc and Stratafix, and both have not been compared to each other with regard to flexor tendon repair. The purpose of this study was to evaluate both suture materi...

DESCRIPTION A 14-year-old adolescent boy presented 3 days after lacerating his hand with a knife. He complained of inability to flex his little finger and had decreased sensation on the ulnar aspect of this digit.

Spontaneous rupture at the distal part of the gastrocnemius tendon (GT) is the second most common non-traumatic tendon injury in dogs, whereas the other strands of the common calcaneal tendon do not seem to have a predisposition to rupture. In order to discover why we investigated the common calcaneal tendons of 63 dogs microscopically and biomechanically. Both the gastrocnemius and superficial...

Moment arm, muscle architecture, and tendon compliance in cadaveric human forearms were determined and used to model the wrist torque-joint angle relation (i.e. wrist torque profile). Instantaneous moment arms were calculated by differentiating tendon excursion with respect to joint rotation. Maximum isometric tension of each wrist muscle-tendon unit was predicted based on muscle physiological ...

CASE DESCRIPTION A 25 years old man presented with a laceration on radial side of proximal phalanx of 4(th) finger (zone II flexor) which was due to cut with glass. CLINICAL FINDINGS The sheaths of Tendons of flexor digitorum superficialis and profundus were not the same and each tendon had a separate sheath. TREATMENT AND OUTCOME The tendons were reconstructed by modified Kessler sutures, ...

In this report we describe our encounter of a case of hand trauma referred to our center presenting with incomplete left thumb amputation at metacarpal level with extensor pollicis longus (EPL) and flexor pollicis longus (FPL) tendon avulsion from the tenomuscular junction. After metacarpal bone fixation the ulnar digital artery was anastomosed and the digital nerves were coapted. Transfer of e...

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...
