Current rodent models of neuropathic pain produce pain hypersensitivity in almost all lesioned animals and not all identified experimental effects are pain specific. 18G needlestick-nerve-injury (NNI) to one tibial nerve of outbred Sprague-Dawley rats models the phenotype of Complex Regional Pain Syndrome (CRPS), a post-traumatic neuropathic pain syndrome, leaving roughly half of NNI rats with ...

Accurate quantitative measurements of micromovement immediately after operation would be a reliable indicator of the stability of an individual component. We have therefore developed a system for measuring micromovement of the tibial component using three non-contact displacement transducers attached to the tibial cortex during total knee arthroplasty (TKA). Using this system we measured the in...

OBJECTIVE To describe the typical tibial diaphyseal fracture ("footballer's fracture") and to clarify the circumstances and mechanism of the injury. METHODS In an attempt to obtain a detailed analysis of the types of injury suffered, and thereby highlight areas for prevention, 100 consecutive adult football players with a tibial diaphyseal fracture were studied prospectively. Details of the c...

Background and objective: Open tibial fracture with or without bone loss in gustilo Anderson type IIIA and IIIB has been a challenge for most orthopaedic surgeons. Open tibial fracture is more prone for infection, non union and longer morbidity. In this study, we have evaluated the results of 34 patients with open tibial fracture GA type IIIA and IIIB by Ilizarov method in retrospective manner....

BACKGROUND The ability of peripheral nerves to stretch and slide is thought to be of paramount importance to maintain ideal neural function. Excursion in peripheral nerves such as the tibial can be measured by analysis of ultrasound images. The aim of this study was to assess the degree of longitudinal tibial nerve excursion as the ankle moved from plantar flexion to dorsiflexion in a standardi...

Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening. Using non-linear finite element analysis, whether a tibial tray with a circumferentially flanged rim and a mating cut in the proximal tibia could minimiz...

Despite general agreement on the effects of knee valgus and internal tibial rotation on anterior cruciate ligament (ACL) loading, compelling debate persists on the interrelationship between these rotations and how they contribute to the multi-planar ACL injury mechanism. This study investigates coupling between knee valgus and internal tibial rotation and their effects on ACL strain as a quanti...

background: several systemic factors and hormones are thought to regulate the fracture healing process. vitamin d has emerged as a compound or hormone that actively participates in the regulation of calcium homeostasis and bone metabolism. objectives: the aim of this study is to determine the serum changes in the level of vitamin d during the acute healing period of tibial and femoral shaft fra...
