This study compared radiological and clinical results of Mallory-Head (Biomet, Warsaw, Indiana) cementless total hip arthroplasty (THA) by anatomical (AP group) or high cup placement (HP group) for Crowe I to III developmental dysplasia of the hip. Of the 68 hips studied, 43 hips were available for 15.3-year follow-up. Ten cups were placed at anatomical center with bulk bone grafting, and 33 cu...

The number of grafting procedures, including those performed in primary and revision hip arthroplasty, continues to rise around the world. Demand for musculoskeletal donor tissue now outstrips supply. There is no single bone substitute that is ideal for all circumstances. Bone substitutes act as a scaffold and are usually osteoconductive. They are rarely osteoinductive; if they are, a molecular...

PURPOSE To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA). METHODS 62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent unc...

densitometry devices. Many studies have shown a strong relationship between bone density at virtually any skeletal site and the subsequent risk for fractures of the spine, hip, and forearm.1 The exact strength of this relationship depends on the type of fracture and the skeletal site measured. In most cases, the relationship between bone density and fracture by analogy is as strong or stronger ...

A 61-year-old Japanese man underwent right total hip arthroplasty for hereditary multiple exostosis. At first presentation, he had suffered from coxalgia for a long time. On radiographic images, there was a gigantic femoral head, increased shaft angle, and large diameter of the femoral neck. He had also developed coxarthrosis and severe pain of the hip joint. The transformation of the proximal ...

OBJECTIVE To analyze the treatment effect of surgical dislocation of the hip with sequestrum clearance and impacting bone graft in grade IIIA-IIIB aseptic necrosis of femoral head (ANFH) patients. METHODS From June 2012 to December 2014, 6 patients (total 8 hips) with grade IIIA-IIIB ANFH were retrospectively followed. All the patients were operated with surgical dislocation of the hip with s...

We have undertaken a prospective, randomised study to compare conservation of acetabular bone after total hip replacement and resurfacing arthroplasty of the hip. We randomly assigned 210 hips to one of the two treatment groups. Uncemented, press-fit acetabular components were used for both. No significant difference was found in the mean diameter of acetabular implant inserted in the groups (5...

Improved hip kinematics and bone preservation have been reported after resurfacing total hip replacement (THRS). On the other hand, hip kinematics with standard total hip replacement (THR) is optimized with large diameter femoral heads (BFH-THR). The purpose of this study is to evaluate the functional outcomes of THRS and BFH-THR and correlate these results to bone preservation or the large fem...

OBJECTIVE: To explore the prevalence of osteopenia and osteoporosis within a cohort Pakistani postmenopausal women with respect to lumbar spine hip. METHODS: This cross-sectional study was conducted at Shifa International Hospital Islamabad, Pakistan from September 2019 Feb 2020. Study comprised 237 females who visited outpatient department hospital. The T-scores Bone Mineral density (BMD) data...
