The aim of this study was to assess the influence of bone mineral density and hip geometry on the fragility fracture of femoral neck and trochanteric region. There were 95 menopausal females of age ≥ 50 years with fragility fracture of hip, including 55 cases of femoral neck fracture and 40 cases of trochanteric fracture. Another 63 non-fractured females with normal bone mineral density (BMD) w...

PURPOSE Excessive in-spica abduction is a risk factor for oste-onecrosis after surgical reduction for developmental dysplasia of the hip (DDH). The traditional method for radiographically measuring hip abduction using axial imaging does not reflect the true angle, which usually lies in an oblique plane. The purpose of this study was to describe a novel method for measuring true hip position usi...

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...

We examined the hypothesis that structural features of the iliotibialis lateralis pars postacetabularis (ILPO) in guinea fowl allow this large muscle to maintain equivalent function along its anterior-posterior axis. The ILPO, the largest muscle in the hindlimb of the guinea fowl, is a hip and knee extensor. The fascicles of the ILPO originate across a broad region of the ilium and ischium post...

BACKGROUND A quantitative and accurate measurement of the range of hip joint flexion (RHF) is necessarily required in the evaluation of disordered or artificial hip joint function. This study aimed to assess a novel method to measure RHF more accurately and objectively. METHODS Lateral radiographs were taken of 31 supine men with hip joints extended or flexed. Relevant angles were measured di...

These words of the old master of ortho­ paedics, Georg Hohmann, from his book "Fuss und Bein" are still applicable today. Thirty years later, the biomechanics of the foot have still not been completely explained, and there are many questions yet unanswered. The many, more or less articulated connec­ tions of the foot allow a variety of changes which make it difficult to understand the move­ men...

background: the aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3d reconstructive ct scan imaging. methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. preoperatively, all the patients underwent a ct scan according to a standard prot...

To assess the postural strategies developed by patients after total hip arthroplasty (THA), 14 patients were measured 12 days after surgery. The respective role played by both sound and prosthetic legs and the compensatory mechanisms were assessed through a separate measure of the center-of-pressure (CP) trajectories under each foot. The movements of the center-of-gravity (CG) were estimated fr...

Many female college students in South Corea suffer from postural problems and deformities in their lower extremities. In particular, many females exhibit knee valgus or varus. These problems can arise from a variety of causes, from the use of elevated heels, to years of carrying heavy backpacks, and muscle imbalance. There are many different types of exercises to address these problems, but iso...
