Pathological fractures in predicting clinical outcomes for patients with osteosarcoma.

Background: Studies reported contradictory results for the prognostic significance of a pathological fracture in osteosarcoma patients. The aim of this study is to report the outcomes for a cohort of patients with osteosarcoma who presented with and without pathological fractures and to identify the prognostic importance of pathological fracture in predicting outcomes and influences on survival.

Methods: Data of patients with osteosarcoma were retrospectively reviewed.

Total Hip Arthroplasty for Patients Who Have Ankylosing Spondylitis: Is Postoperative Irradiation Required for Prophylaxis of Heterotopic Ossification?

Postoperative radiation for prevention of heterotopic ossification (HO) has been proven effective for the patients with ankylosing spondylitis (AS) after total hip arthroplasties (THA). This study aims to evaluate the effect of postoperative radiation in HO formation following THA in patients with AS. We retrospectively reviewed 129 hips from 91 patients with AS receiving primary THA from July 2004 to December 2012.

Acremonium species combined with Penicillium species infection in hip hemiarthroplasty: a case report and literature review.

Objective: To illustrate that Acremonium and Penicillium species are being increasingly recognised in periprosthetic joint infections (PJIs).

Case Report: A 47-year-old male with liver cirrhosis and bilateral hip hemiarthroplasties complained of persistent right hip pain. Bone scan was suspicious for right hip septic arthritis.

Population-based epidemiology of postoperative venous thromboembolism in Taiwanese patients receiving hip or knee arthroplasty without pharmacological thromboprophylaxis.

Introduction: Population-based evaluation on the incidence of postoperative venous thromboembolism (VTE) has not yet been reported for Asians receiving arthroplasty. In Taiwan, thromboprophylaxis was not commonly applied for patients. The population-based cohort study aimed to investigate the epidemiology, and to determine the risk factors VTE for patients receiving hip or knee replacement without pharmacological thromboprophylaxis in Taiwan.

Pulmonary embolism following total knee arthroplasty in Taiwanese patients.

Background: Pulmonary embolism is a relatively uncommon, but serious, postoperative complication of hip and knee arthroplasty; however, little information is available about the prevalence of pulmonary embolism in Taiwan.

Methods: We report here a series of five patients who sustained a symptomatic pulmonary embolism after undergoing total knee arthroplasty (TKA). These patients were identified during a retrospective study of 1768 patients carried out between January 2007 and January 2010.

Extensively porous-coated stems for femoral revision: reliable choice for stem revision in Paprosky femoral type III defects.

Between January 1999 and August 2008, ninety-six femoral revisions were performed with extensively porous-coated stems in Paprosky type III femoral defects (89 type IIIA and 7 type IIIB defects). Seven type IIIB defects with a mean canal of 16.5 mm were observed; 6 defects achieved stable bone ingrowth and 1 achieved stable fibrous condition.

High-grade osteosarcoma treated with hemicortical resection and biological reconstruction.

Background And Objectives: Wide excision with a 2-3 cm safe margin is widely-accepted in treating high-grade osteosarcoma. However, a wider margin sacrifices more healthy bone and may jeopardize joint function. We hypothesize that our innovative hemicortical resection for such tumors leads to better joint function without higher recurrence rate.

Deep vein thrombosis after total knee arthroplasty in asian patients without prophylactic anticoagulation.

Deep vein thrombosis (DVT) is an important complication following total knee arthroplasty (TKA). However, the incidence of DVT is generally underestimated due to subclinical or minor symptoms and signs. In Western countries, prophylactic agents against DVT are administered routinely after TKA.
