Since hip arthroscopy has become a standard of orthopaedic practice, the indications have continued to expand as it has proved to be a helpful diagnostic, as well as therapeutic, tool. Access to the hip joint, however, remains challenging for the orthopaedic surgeon who does not routinely perform hip arthroscopy. We present a single-portal arthroscopic technique, showing the feasibility of sing...

BACKGROUND/AIMS To evaluate the clinical course of hip arthritis and the risk factors for hip joint replacement in patients with ankylosing spondylitis (AS). METHODS In this retrospective analysis, we evaluated 488 AS patients at a single tertiary hospital. At baseline and the most recent visit to the outpatient clinic from the patients with hip arthritis in AS, radiographic hip arthritis was...

hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. we present the case of a 26 year old patient involved in motor vehicle accident. clinical and imaging (radiography, ct) examination revealed an intertrochanteric fracture associated with ipsi...

OBJECTIVE To study the prevalence of ultrasonic hip joint effusion and its relation with clinical, radiological and laboratory (ESR) findings in adults with hip pain. METHODS Patients (n = 224) aged 50 years or older with hip pain, referred by the general practitioner for radiological investigation, underwent a standardised examination. The distance between the ventral capsule and the femoral...

Mechanical stress on articular cartilage and long-duration standing postures are risk factors for hip osteoarthritis progression. This study aims to examine the relationship between hip flexion contracture and the hip-joint contact force in standing postures using computer simulation. A musculoskeletal model composed of seven segments (Head, Arms, and Trunk (HAT) and thighs, shanks, and two fee...

OBJECTIVES We used the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR) to investigate the risk of revision due to prosthetic joint infection (PJI) for patients undergoing primary and revision hip arthroplasty, the changes in risk over time, and the overall burden created by PJI. METHODS We analysed revision total hip arthroplasties (THAs) performed due t...

normal range of joint motion is an important factor in joint examination in clinical practice which is related to factors such as age, sex and geographic region. there is no data in the literature on the range of joint motions in healthy iranian adults. we studied joint motions in 100 healthy volunteer subjects, 49 men and 51 women, from 19 and 58 years of age. the joint mobility was examined i...

Coupling of spine and hip joints during full body reaching tasks was investigated in 16 participants (8 male and 8 female) who performed reaching tasks at comfortable and fast-paced movement speeds to three targets located in a para-sagittal plane. The participants paused at target contact for 500ms and then returned to an upright posture. Three-dimensional joint motions of the spine and hip we...

OBJECTIVE To evaluate the effects of diet restriction on development of radiographic evidence of hip joint osteoarthritis in dogs. DESIGN Longitudinal cohort study. ANIMALS 48 Labrador Retrievers from 7 litters. PROCEDURES Forty-eight 6-week-old puppies from 7 litters were paired with littermates by sex and weight, and each pairmate was randomly assigned to 1 of 2 groups of 24 dogs each. ...
