Traumatic laceration of the tibialis anterior tendon complicating a closed tibial shaft fracture is a rare injury pattern. Only 3 such cases have been reported to date in the English literature and all were missed on initial examination. A case of a 17-year-old motorcyclist with an acute laceration of the tibialis anterior tendon resulting from a closed oblique tibial shaft fracture is presente...

BACKGROUND Tendon is an integral part of joint movement and stability, as it functions to transmit load from muscle to bone. It has an anisotropic, fibrous hierarchical structure that is generally loaded in the direction of its fibers/fascicles. Internal load distributions are altered when joint motion rotates an insertion site or when local damage disrupts fibers/fascicles, potentially causing...

INTRODUCTION This study retrospectively analyzes primary extensor tendon repairs in children younger than 15 years. METHODS Exclusion criteria were skin loss, devascularization, fractures, or flexor tendon injuries. Fifty patients who had sustained extensor tendon laceration with 53 digits injured were available for review. Treatment consisted of primary repair of the extensor tendon injury w...

This article describes a technique for improved repair of digital flexor tendon laceration. Eight-strand cross-locked cruciate repair using 4-0 caliber double-stranded suture is not bulky and has a smooth configuration for tendon gliding. Additionally, it has sufficient strength for early postoperative active motion exercise.

We carried out lacerations of 50%, followed by trimming, in ten turkey flexor tendons in vitro and measured the coefficient of friction at the tendon-pulley interface with loads of 200 g and 400 g and in 10 degrees , 30 degrees, 50 degrees and 70 degrees of flexion. Laceration increased the coefficient of friction from 0.12 for the intact tendon to 0.3 at both the test loads. Trimming the lacer...

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...

We present the case of a patient with flexor digitorum profundus tendon laceration at the A2 pulley level caused by an injury to the base of the right ring finger by a knife. The patient was treated by flexor tendon reconstruction from the palm to the fingertip by using the left second toe flexor tendon as a graft, which improved the active range of motion. Further improvement was achieved by s...
