The functional outcomes of periacetabular osteotomy (PAO) and factors predicting outcome in the older patient with acetabular dysplasia are not well understood. We therefore retrospectively determined the functional outcome of 70 patients (87 hips) over age 40 treated with PAO in three institutions; we also determined whether preoperative factors, particularly the presence of osteoarthritis, in...

Femoroacetabular impingement secondary to the cam effect is thought to be associated with an insufficient anterior concavity in the sagittal/axial plane of the femoral head-neck junction. Using three-dimensional computed tomography the anterior and posterior concavity of the femoral head-neck junction was assessed in 36 painful non-dysplastic hips (30 patients). The mean age of the symptomatic ...

Bone mineral density (BMD) using dual energy radiography absorptiometry are commonly used for the diagnosis of osteoporosis. It is usually measured at the spine and also at one hip joint. Controversy still exists regarding the use of bilateral hip scanning. We analyzed the difference of BMD at bilateral hips in 384 postmenopausal women, retrospectively. The concordance and discordance rates of ...

There is debate over whether the horizontal segment of the intraparietal sulcus (HIPS) houses a domain-specific number module (Ansari, 2008). Here, we address the debate in two ways. First, using cross-domain modeling (Penner-Wilger & Anderson, 2011) we show that bilaterally the HIPS shows activation across a wide range of non-numerical tasks in diverse domains including perception, action, cog...

developmental dysplasia of the hip (ddh) is one of the most widely discussed abnormalities in neonates. the advantages of sonographic examination are well known, but its main disadvantage is that it might lead to over diagnosis, which might cause over treatment. variations in the incidence of developmental dysplasia of the hip are well known. during six months study since september 2006 all 130...

Introduction: In recent studies using MR imaging, poor results of worsening pain in patients with osteonecrosis of the femoral head were reported in 23% to 62% [1–3]. The necrotic volume was reported to be one of the most significant factors for worsening of hip pain [4]. Bone marrow edema at the femoral head and neck was reported to be observed in patients with osteonecrosis, having a strong a...

Hip contact stress is considered to be an important biomechanical factor related to development of coxarthrosis. The effect of the lateral coverage of the acetabulum on the hip contact stress has been demonstrated in several studies of hip dysplasia, whereas the effect of the anterior anteversion remains unclear. Therefore, the joint hip contact stress during normal level walking and staircase ...

BACKGROUND Authors analysed the post-operative course of the hip joints in ICP children following two types of surgery. MATERIAL AND METHODS We analysed 50 children with CP (100 hips) treated in our department between 1999-2004 whose radiological records were complete. The children were divided into 2 groups of those following open adductor tenotomy and those treated according to Gob's method...

ANALYSIS In previous research we introduced a framework for understanding the different protection styles and technologies in the market for host-based intrusion prevention systems (HIPSs). Since then, we have been asked, “What’s the best HIPS protection style?” The answer is that there is no “silver bullet.” No single protection style alone provides sufficient protection, and different organiz...
