BACKGROUND The clinimetric properties of knee goniometry are essential to appreciate in light of its extensive use in the orthopaedic and rehabilitative communities. Intra-observer reliability is thought to be satisfactory, but the validity and inter-rater reliability of knee goniometry often demonstrate unacceptable levels of variation. This study tests the validity and reliability of measurin...

The goal of this research was to examine the accuracy of three methods used to indicate the hip joint center (HJC) in seated steady-state cycling. Two of the methods have been used in previous studies of cycling biomechanics and included tracking a marker placed over the superior aspect of the greater trochanter, a location that estimates the center of rotation of the hip joint, and assuming th...

Lateral hip snapping is a nosological entity that is often unknown to many orthopedists and even to some hip surgery specialists. It comprises palpable and/or audible snapping on the lateral face of the hip that is sometimes painful, caused by muscle-tendon friction on the greater trochanter during flexion and extension of the coxofemoral joint. In the following, we describe a new test for diag...

BACKGROUND The aim of the study was to analyse the outcomes of hip replacement complicated by intraoperative femoral fractures and to analyse their effective management. MATERIALS AND METHODS The medical records of 43 cases of intraoperative femoral fractures (1.4% of all hip replacements) were retrospectively reviewed. The patient group included 29 females. Patients' age ranged from 20 to 66...

OBJECTIVE To evaluate the diagnostic accuracy of 10 clinical tests that can be used in the diagnosis of greater trochanteric pain syndrome (GTPS) in women, and to compare these clinical tests to magnetic resonance imaging (MRI) findings. MATERIALS AND METHODS Twenty-eight participants with GTPS (49.5 ± 22.0 years) and 18 asymptomatic participants (mean age ± standard deviation [SD], 52.5 ± 22...

PURPOSE To describe a variant of intertrochanteric fracture not well-characterised in the existing classification systems. METHODS 10 women and 2 men aged 59 to 98 (median, 80) years with intertrochanteric fractures characterised by a low intertrochanteric fracture, a basicervical fracture fragment, and a thin or fractured lateral wall with greater trochanteric comminution were reviewed. RE...

BACKGROUND High caffeine intake is reportedly a risk factor for reduced bone mineral density (BMD) in women. Most studies, however, are from populations in which coffee drinking predominates and is the major caffeine source. Tea contains caffeine but also has other nutrients, such as flavonoids, that may influence bone mass in different ways. OBJECTIVE We examined the relation between tea dri...

We describe a case of traumatic anterior dislocation of the hip in a 14-year-old boy with associated intrapelvic displacement of the femoral head and ipsilateral fractures of the shaft of the femur and greater trochanter. There was a delay in presentation of eight days. At operation the femoral head was reduced into the acetabulum after enlarging the obturator foramen by performing an osteotomy...
