Purpose: Blind intra-articular injections (BIAI) of various joints are performed for diagnosis and treatments of different pathologies in sport medicine, rheumatology, general practice and orthopaedics. The gold standard for any joint injection is image guidance but studies have shown higher accuracy for BIAI. Objective of this study was to evaluate the intraoperative success and accuracy of an...

INTRODUCTION Load variation is associated with changes in joint torque and compensatory reflex activation and thus, has a considerable impact on balance control. Previous studies dealing with over (OL) and under loading (UL) used water buoyancy or additional weight with the side effects of increased friction and inertia, resulting in substantially modified test paradigms. The purpose of this st...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-009038 DESCRIPTION A 17-year-old boy with Haemophilia A was referred to an orthopaedic surgeon with pain and swelling in the right ankle. His medical history included incidents of right ankle trauma. On physical examination, there was swelling and increasing te...

This study presents the ankle ligament strains and ankle joint moments during an accidental injury event diagnosed as a grade I anterior talofibular ligament (ATaFL) sprain. A male athlete accidentally sprained his ankle while performing a cutting motion in a laboratory setting. The kinematic data were input to a three-dimensional rigid-body foot model for simulation analyses. Maximum strains i...

BACKGROUND Ankle ligamentous sprain is common in sports. The most direct way to study the mechanism quantitatively is to study real injury cases; however, it is unethical and impractical to produce an injury in the laboratory. A recently developed, model-based image-matching motion analysis technique allows quantitative analysis of real injury incidents captured in televised events and gives im...

[Purpose] We investigated the effect of rhythmic ankle movement on the contralateral soleus H-reflex. The H-reflex was evoked from the right soleus muscle. [Subjects and Methods] Healthy humans rhythmically moved the left ankle (movement condition) or held the left ankle stationary (stationary condition) at one of three positions corresponding to the ankle positions at which the H-reflex was ev...

Ankle sprains are the most frequently occurring orthopedic injury among the physically active. The number 1 risk factor for suffering an ankle sprain is a history of a previous sprain. Those with a history of ankle sprain often report recurrent bouts of ankle instability and decreased functional capacity. Several mechanical and functional deficits have been identified that may contribute to res...

The present study was aimed to test a hypothesis that individuals with functional ankle instability (FAI) underestimate the joint angle at greater plantarflexion and inversion. Seventeen males with unilateral FAI and 17 controls (males without FAI) consented for participation in this IRB-approved, case-control study. Using a passive reproduction test, we assessed ankle joint position sense (JPS...

There is no standardized method reported in the literature to measure ROM of the ankle after a total ankle arthroplasty, which limits the possibility to compare results from the various ankle designs. It seems that most of the measurements are a combination of ankle and midfoot motion, not the tibiotalar joint. A protocol was developed to accurately measure the true tibiotalar and midfoot motio...

This paper summarizes the current understanding on acute ankle sprain injury, which is the most common acute sport trauma, accounting for about 14% of all sport-related injuries. Among, 80% are ligamentous sprains caused by explosive inversion or supination. The injury motion often happens at the subtalar joint and tears the anterior talofibular ligament (ATFL) which possesses the lowest ultima...
