PURPOSE To assess mid- to long-term outcomes of cementless primary total hip arthroplasty (THA) in younger patients. METHODS Records of 28 women and 34 men (75 hips) aged 18 to 55 (mean, 38) years who underwent primary THA using a hydroxyapatite-coated stem and a threaded cup and had been followed up for a mean of 10 (6-15) years were reviewed. 13 of the patients had bilateral THAs. Clinical ...

Abstract Background Osteonecrosis of the femoral head (ONFH) is a disabling disease, which often involves young patients. Recently, various hip-preserving surgeries were recommended to delay total hip arthroplasty (THA). Questions/purposes This study aimed compare clinical outcomes and survival rate in long-term follow-up between core decompression combined with non-vascularized autologous fibu...

Total hip arthroplasty (THA) is one of the most cost-effective hip surgeries among orthopedic procedures. We conducted an extensive literature review with 5,394 papers regarding survival rates after THA. We searched PubMed, Embase and the Cochrane library from January 1(st), 1970 to July 31(th), 2014 looking for all citations about total hip arthroplasty with a long term follow-up (longer than ...

The metabolic fate of tacrine [1,2,3,4-tetrahydro-9-acridinamine monohydrochloride monohydrate (THA)] was examined in rats, dogs, and humans. After administration of single oral doses of [14C]THA to rats, dogs, and humans, drug-derived material was well absorbed, with urinary excretion being the predominant route of radiolabel elimination. Metabolic profiling of plasma and urine from rats, dogs...

With the arrival of an aging society and progress surgical procedures, total hip arthroplasty (THA) has been carried out more more. However, postoperative pain severely affected patient’s recovery, there is currently no reliable analgesic method available. Evidence-based international expert consensus also recommends, compared to LIA, peripheral nerve block (PNB) as a central approach use in TH...

Kristian Kjær Petersen, PhD Lars Arendt-Nielsen, Dr Med Sci, PhD Center for Sensory-Motor Interaction Department of Health Science and Technology Aalborg University Aalborg, Denmark T otal joint arthroplasty (TJA) surgery is considered to be an effective intervention to improve function and reduce pain in conditions such as end-stage knee osteoarthritis (OA). In the United States alone, the num...

Total hip arthroplasty (THA) for high congenital hip dislocation (CHD) is technically demanding. The purpose of this retrospective study was to evaluate the results of cementless THA combined with extended sliding trochanteric osteotomy. We also assessed whether chronic low back pain was relieved after surgery.The study included 19 patients (23 hips) with high CHD treated with cementless THA us...

BACKGROUND AND PURPOSE Whether or not uncemented total hip arthroplasty (THA) can achieve durable fixation of implants to bone in patients on chronic hemodialysis is unknown. We analyzed the 2-13-year clinical outcomes of cementless THA in patients with end-stage renal diseases who were maintained on long-term hemodialysis. PATIENTS AND METHODS We reviewed the outcome of 23 consecutive unceme...

Bose and Chaudhuri (1960) have introduced a class of binary errorcorrecting codes of block length 2 ~ 1, m = 2,3,• • which we refer to here as B-C codes. An efficient decoding scheme has been devised for them by Peterson (1960), and generalized to the natural extension of the B-C Codes to codes in pm symbols by D. Gorenstein and N. Zierler (1960). Two further properties of B-C codes are establi...
