BACKGROUND: Well-designed studies of complications and readmission rates in patients undergoing total hip arthroplasty (THA) with osteonecrosis are lacking. Our objective was to examine if a diagnosis of osteonecrosis was associated with complications, mortality and readmission rates after THA. METHODS: We analyzed prospectively collected data from an integrated healthcare system's Total Joint Replacement Registry of adults with osteonecrosis vs. osteoarthritis (OA) undergoing unilateral primary THA during 2001-2012, in an observational cohort study...

BACKGROUND: Total ankle arthroplasty (TAA) is a rapidly growing treatment for end-stage ankle arthritis that is generally performed as an inpatient procedure. The feasibility of outpatient total ankle arthroplasty (OTAA) has not been reported in the literature. We sought to establish proof of concept for OTAA by comparing outpatient vs inpatient perioperative complications, postoperative emergency department (ED) visits, readmissions, patient satisfaction, and cost analysis. METHODS: From July 2010 to September 2015, a total of 36 patients underwent TAA...

Mycobacterium avium complex is a rare cause of musculoskeletal infection, usually occurring in patients with compromised immune systems. Obtaining the diagnosis requires a high index of suspicion, and treatment can be delayed because of difficulty with isolating the organism. Treatment involves prolonged, targeted combination antibiotic therapy, and it is unclear whether eradication of the infection can occur in the presence of a foreign body, such as antibiotic spacers. The authors report a case of M avium infection presenting as presumed osteonecrosis of the femoral head in a young woman with systemic lupus erythematosus...

PURPOSE: Traditionally and since Neer, the humeral side of shoulder arthroplasty consisted of a stemmed component but the real need for stem fixation in total shoulder arthroplasty (TSA) has barely been investigated. The current study evaluated the clinical and radiological outcomes with a stemless TSA. METHODS: Forty-seven patients, 20 female and 27 male patients with an average age of 63, were selected in four orthopaedic centres during a four year period, and implanted with a humeral head prosthesis with a three-fin design and titanium coating...

Periprosthetic infection following total hip arthroplasty is a devastating complication that has been reported to occur in up to 1.6% of all primary total hip arthroplasties. We report a previously unrecognized gram-negative bacillus as the infecting agent in a patient with bilateral total hip arthroplasties for stage IV osteonecrosis. A 22-year-old male with combined sickle cell disease and beta thalassemia with a prior history of unknown hip surgeries and treatment for distal tibial osteomyelitis in Africa developed a periprosthetic joint infection; intra-operative cultures confirmed the infecting organism to be Edwardsiella tarda which was sensitive to late-generation cephalosporins and vancomycin...

OBJECTIVE: Although there are many etiology and prediction for prognosis of spontaneous osteonecrosis of the knee (SONK) by using radiological examinations, these issue have not been clarified yet. Furthermore, most of the studies evaluated them by only radiological examination such as magnetic resonance imaging (MRI), bone mineral density (BMD) in dual-energy X-ray abosorptiometry (DEXA) or plain X-ray. Therefore, we focused our investigation on the measurements of the affected área in MRI and BMD in DEXA, and whether these results were conected with the cause and prognosis of SONK or not...

BACKGROUND: Patient-reported scoring systems have recently been used after surgical procedures. The purpose of this prospective study was to evaluate the patient-reported outcomes of femoral osteotomy and total hip arthroplasty (THA) for osteonecrosis of the femoral head (ONFH). METHODS: Forty-two symptomatic ONFH patients with asymptomatic contralateral hip underwent either transtrochanteric anterior rotational osteotomy (ARO) or THA as a primary operation. Of these, 20 patients whose contralateral hips remained asymptomatic at the final follow-up (more than 1 year postoperatively) were recruited to participate in this study...

To present the morphological changes of classic primary versus rapidly progressive and secondary hip osteoarthritis (HO) and to examine the expression of two pluripotent mesenchymal stem cell-like markers in the synovial membrane. A prospective observational study was conducted in 57 consecutive cases of radiologically confirmed HO in which total hip arthroplasty was performed. Based on the radiological and clinicopathological features, the cases were divided into three categories: classic primary HO (group A; n=16), rapidly destructive HO (group B; n=24), and HO secondary to avascular osteonecrosis of the femoral head (group C; n=17)...

Osteonecrosis is one of the most devastating musculoskeletal manifestations of sickle cell disease and most commonly affects the femoral head. Although the exact pathophysiology of this condition in patients with sickle cell disease is unknown, it is suggested that red cell sickling and repetitive vaso-occlusion may be associated with tissue hypoxia, inflammation, and subsequent bone necrosis and collapse. If left untreated, osteonecrosis can be extremely debilitating and may lead to severe pain, loss of function, and degenerative joint changes...
