BACKGROUND: Intra-operative estimation of stem anteversion in total hip arthroplasty (THA) using postero-lateral approach is made by the surgeon's visual assessment, using the tibia as a guide, with the assumption that tibial axis is vertical to the trans-epicondylar axis. However, the accuracy of the intra-operative estimation has rarely been verified with postoperative CT-scans, with controversies regarding these measurements particularly in case of knee osteoarthritis. Therefore we performed a prospective study to: 1) determine the accuracy of the intra-operative measurement and 2) investigate factors affecting the discrepancy between the surgeon's estimation and the real stem anteversion HYPOTHESIS: Intra-operative estimation of stem anteversion correlated with the real stem anteversion on CT scan...

INTRODUCTION: The incidence of periprosthetic femoral fracture is constantly increasing, with high associated morbidity and mortality. Surgical treatment is guided by the Vancouver classification, but the influence of type of treatment on morbidity and mortality has been little analyzed. The theoretic advantage of implant revision over internal fixation is that it should allow earlier weight-bearing, although the impact of this on morbidity and mortality and autonomy has not been demonstrated...

Purpose To determine if 3-T magnetic resonance (MR) imaging of proximal femur microarchitecture can allow discrimination of subjects with and without fragility fracture who do not have osteoporotic proximal femur bone mineral density (BMD). Materials and Methods Sixty postmenopausal women (30 with and 30 without fragility fracture) who had BMD T scores of greater than -2.5 in the hip were recruited.

INTRODUCTION: Postoperative chronic pain is an important outcome of hernia surgery. In laparoscopic hernia surgery, either fixation outside the trapezoid of disaster or no fixation is recommended to avoid postoperative pain. To avoid recurrence are transabdominal preperitoneal (TAPP) hernia repair, the myopectineal orifice must be covered with mesh during TAPP, but lifting or shrinking of the mesh can lead to recurrence. The aim of this study was to evaluate the feasibility of a novel technique for mesh fixation to prevent the mesh from lifting off...

Jaroslaw Ucieklak, Robert Michał Proczka
A rare case of clinical complication following a percutaneous coronary intervention is presented. A femoral vascular access was chosen to treat a coronary lesion with a stent implantation. This femoral vascular access, however, resulted in a pyogenic infection of the ipsilateral hip joint that was not properly diagnosed for an extended post-interventional period. The hip joint completely deteriorated before its underlying cause was identified. This case report illustrates the importance of recognizing potential endovascular complications independently of their frequency...

Purpose: Sickle cell disease (SCD) is the most common cause of femoral head osteonecrosis (ONFH) during childhood with an overall prevalence of 10%. In children, spontaneous revascularization can occur, as in Legg-Calve-Perthes disease. Consequently, the aim of treatment is to restore proper hip containment to prevent joint arthritis. This is the first study reporting long-term results at skeletal maturity of non-operative and surgical treatments for ONFH in SCD children. Methods: All children with ONFH due to SCD were retrospectively reviewed...
