Background and purpose - Femoral neck fractures (FNFs) are commonly treated with some kind of arthroplasty, but evidence on whether to use hemiarthroplasty (HA) or total hip arthroplasty (THA) is lacking. HA reduces the risk of dislocation, but may lead to acetabular erosion. THA implies longer surgery and increased bleeding. THA may result in better function and health-related quality of life,...

This study evaluated the outcomes of using porous tantalum rods for the treatment of osteonecrosis of the femoral head (ONFH). We performed core decompression and inserted porous tantalum implants in 149 patients (168 consecutive hips) with ONFH. Hips had large (65), medium (64), or small (39) lesions; 63 lesions were lateral, 68 were central, and 35 were medial. Conversion to total hip arthrop...

BACKGROUND AND PURPOSE The use of hip arthroplasties is evidently increasing, but there are few published data on the incidence in young patients. METHODS We used data on total and resurfacing hip arthroplasties (THAs and RHAs) from the Finnish Arthroplasty Register and population data from Statistics Finland to analyze the incidences of THA and RHA in patients aged 30-59 years in Finland, fo...

PURPOSE Patients who have secondary hip osteoarthritis as sequelae of Legg-Calvé-Perthes disease (LCPD) are severe deformities of femoral head and acetabulum. A few studies have presented that the clinical results and risks associated with total hip arthroplasty (THA) for patients with a history of LCPD were not satisfactory. In this study, we reported the radiographic and clinical outcomes of ...

BackgroundScarce data exist on differential opioid prescribing between men and women in the pre-, peri-, postoperative phases of care among patients undergoing total hip/knee arthroplasty (THA/TKA).MethodsIn this retrospective population-based study, Truven Health MarketScan claims were used to establish differences (1) year before THA/TKA surgery, (2) amount opioids prescribed at discharge, (3...

BACKGROUND AND PURPOSE It has been suggested that the risk of prosthetic joint infection (PJI) in patients with total hip arthroplasty (THA) may be underestimated if based only on arthroplasty registry data. We therefore wanted to estimate the "true" incidence of PJI in THA using several data sources. PATIENTS AND METHODS We searched the Danish Hip Arthroplasty Register (DHR) for primary THAs...

Fascia Iliaca Compartment Block (FICB) has been widely used as a postoperative analgesic adjunct to opioids for total hip arthroplasty (THA), either by the conventional infrainguinal approach or the modified proximal suprainguinal approach irrespective of any specific advantage of one over the other. This study was conducted to compare the analgesic efficacy of the two techniques of FICB for po...

BACKGROUND Heterotopic ossification is a common postoperative complication of acetabular fracture. However, functionally significant heterotopic ossification with associated late bone defects in the posterior wall of the acetabulum is rare and challenging to treat. When heterotopic ossification is a late complication of failed acetabular fracture operation, it is disabling and may only be treat...

Avascular necrosis (AVN) may confer an increased risk of complications and readmission following total hip arthroplasty (THA). However, current risk-adjustment models do not account for AVN. A total of 1706 patients who underwent THA for AVN from 2011 to 2013 were selected from the American College of Surgeon's National Surgical Quality Improvement Program database and matched 1:1 to controls u...

Este trabajo propone y evalúa una trayectoria hipotética de aprendizaje (THA) para los conceptos conjunto generador espacio generado. La THA se diseñó siguiendo el planteamiento Simon (1995), la heurística diseño modelos emergentes mecanismo reflexión sobre relación actividad-efecto. Se realizó un experimento con estudiantes universitarios evaluar si contribuyó al esperado conceptos. Para ello,...
