Intraoperative fracture rates in total hip arthroplasty (THA) have been associated with uncemented stems, anterolateral surgical approach, diagnoses other than osteoarthritis, and female gender. The purpose of this study was to investigate if changes in stem design would influence intraoperative fracture rates. 1497 THA with Bi-Metric stems were compared to 1277 THA with Echo Bi-Metric Full Proximal Profile stems and 366 THA with Echo Bi-Metric Reduced Proximal Profile stems. The intraoperative fractures rates were 5.48%, 1.41% and 1.37% for Bi-Metric and Echo Bi-Metric with standard and reduced proximal geometry stems, respectively. Stem survivorship with aseptic loosening as an endpoint was 100% in all cohorts at the final follow-up. We conclude that changes in femoral stem geometry in uncemented THA reduce intraoperative fracture rates while preserving fixation.

Epithelioid angiosarcoma is a rare vascular tumour with dark prognosis at short term. The primitive bone localization is exceptional and sometimes presents itself under a unifocal form. We report a clinical case of pelvic multifocal primitive bone epithelioid angiosarcoma (iliac crest and hip) diagnosed on a young male adult (45 years old). The radiological investigations put in evidence geographic osteolytic lesions (type IC) and, diagnostic was given thanks to the histological examination of the surgical biopsy pieces. The evolution was marked by the appearance of pulmonary and lymph node metastases with a death occurring in less than 4 months. Extremely rare tumour, bone epithelioid angiosarcoma is a variant of angiosarcoma characterised by an aggressive nature whose evolution is always fatal. Through this observation we report our experience on the diagnostic approach;and using a literature review we discuss the therapeutic modalities of this tumour with very bad prognosis.

Objective： To propose a new definition of the pericollapse stage of osteonecrosis of the femoral head （ONFH） and review its significance in disease diagnosis and treatment selection. Data Sources： A search for eligible studies was conducted in three electronic databases including PubMed, Cochrane Library, and Embase up to August 10, 2018, using the following keywords：＂osteonecrosis＂, ＂prognosis＂, and ＂treatment＂. Study Selection： Investigations appraising the clinical signs, symptoms, and imaging manifestations in different stages of ONFH were included. Articles evaluating the prognosis of various joint-preserving procedures were also reviewed. Results： The pericollapse stage refers to a continuous period in the development of ONFH from the occurrence of subchondral fracture to early collapse （〈2 mm）, possessing specific imaging features that mainly consist of bone marrow edema and joint effusion on magnetic resonance imaging （MR1）, crescent signs on X-ray films, and clinical manifestations such as the sudden worsening of hip pain. Accumulating evidence has indicated that these findings may be secondary to the changes after subchondral fractures. Of note. computed tomography provides more information for identifying possible subchondral fractures than does MRI and serves as the most sensitive tool for grading the pericollapse lesion stage. The pericollapse stage may indicate a high possibility of progressive disease but also demonstrates satisfactory long- and medium-term outcomes fbr joint-preserving techniques. In tact, if the articular surface subsides more than 2 mm, total hip arthroplasty is preferable. Conclusions： The pericollapse stage with distinct clinical and imaging characteristics provides a last good opportunity for the use of joint-preserving techniques. It is necessary to separate the pericollapse stage as an independent state in evaluating the natural progression of ONFH and selecting an appropriate treatment regimen.

Background： The lateral pillar of the femoral head is an important site for disease development such as osteonecrosis of the femoral head. The femoral head consists of medial, central, and lateral pillars. This study aimed to determine the biomechanical effects of early osteonecrosis in pillars of the femoral head via a finite element （FE） analysis. Methods： A three-dimensional FE model of the intact hip joint was constructed from the image data of a healthy control. Further, a set of six early osteonecrosis models was developed based on the three-pillar classification. The von Mises stress and surface displacements were calculated for all models. Results： The peak values of von Mises stress in the cortical and cancellous bones of normal model were 6.41 MPa and 0.49 MPa, respectively. In models with necrotic lesions in the cortical and cancellous bones, the von Mises stress and displacement of lateral pillar showed significant variability： the stress of cortical bone decreased from 6.41 MPa to 1.51 MPa （76.0% reduction）, while cancellous bone showed an increase from 0.49 MPa to 1.28 MPa （159.0% increase）; surface displacements of cortical and cancellous bones increased from 52.4 μm and 52.1 μm to 67.9 μm （29.5%） and 61.9 μm （18.8%）, respectively. In addition, osteonecrosis affected not only pillars but also adjacent structures in terms of the von Mises stress and surface displacement levels. Conclusions： This study suggested that the early-stage necrosis in the femoral head could increase the risk of collapse, especially in lateral pillar. On the other hand, the cortical part of lateral pillar was found to be the main biomechanical support of femoral head.
