INTRODUCTION We present a case of accelerated tibial fracture union in the third trimester of pregnancy. This is of particular relevance to orthopaedic surgeons, who must be made aware of the potentially accelerated healing response in pregnancy and the requirement for prompt treatment. CASE PRESENTATION A 40 year old woman at 34 weeks gestational age sustained a displaced fracture of the tib...

Modelling and remodelling adapt bone morphology to accommodate strains commonly encountered during loading. If exceed a threshold threatening fracture, modelling-based formation increases volume reducing these strains. unloading reduces below that inhibits resorption, increased remodelling-based resorption restoring strains, but at the price of compromised microstructure. As weight-bearing regi...

BACKGROUND Most knee joint biomechanics studies have involved knees with an isolated anterior cruciate ligament (ACL) injury. However, a large portion of patients with injured ACLs have accompanied meniscus tearing. In this study, the in vivo alteration of knee biomechanics after tearing the ACL with or without combined medial or lateral meniscus tear was investigated during stair-ascending act...

Objectives: Extreme tensile force to the anterior cruciate ligament (ACL) can cause an avulsion of the tibial eminence which may lead to malunion or nonunion resulting in pain, flexion deformity, and instability of the knee. Since the injury is generally regarded as something equivalent to the ACL injury, the treatment requires anatomic reduction of the fragment and preservation of the stabilit...

OBJECTIVE To determine whether positioning of the tibia affects the degree of tibial external rotation seen during a dial test in the posterior cruciate ligament (PCL)-posterolateral corner (PLC)-deficient knee. DESIGN Laboratory investigation. SETTING Biomechanics laboratory. HYPOTHESIS An anterior force applied to the tibia in the combined PCL-PLC-deficient knee will yield increased tib...

The aim of this study was to evaluate the clinical outcomes of patients with posteromedial tibial plateau fractures treated by open reduction and internal fixation (ORIF) through a posteromedial approach. Thirty-six patients with posteromedial tibial plateau fracture underwent ORIF through a posteromedial approach and were retrospectively analyzed. Pre-operative X-ray pictures and CT images wer...

Background. The combined occurrence of ACL rupture with a posterolateral tibial plateau fracture has not yet been reported. Two cases of such injuries have been treated in our department for the past three years. Findings. The two patients both suffered injuries from traffic accidents. The radiological examinations showed a ruptured ACL with fracture of the posterolateral tibial plateau. Recons...

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 ...

OBJECTIVES To compare the modified Ahlbäck radiological classification with macroscopic analysis of knee injuries and locate a chondral lesion in the tibial plateau, and to correlate this with integrity or lack of integrity of the anterior cruciate ligament. MATERIAL AND METHODS Between July and December 2009, 40 patients of mean age 67.1 years with an indication for total knee arthroplasty w...

Although from an athletic performance perspective it may be beneficial to undertake drop jump training when fatigued (principle of "specificity" of training), such endurance fatigue may expose the body to a greater risk of injury if it causes an increase in peak impact accelerations. This study aimed to determine if endurance fatigue resulted in an increase in tibial peak impact acceleration an...
