Background: Thromboembolic disease is a common complication of total hip arthroplasty. The purpose this study was to compare new mobile compression device with low-molecular-weight heparin regard their safety and effectiveness for the prevention venous thromboembolic disease. Methods: Patients who had arthroplasty were randomized receive prophylaxis or ten days. Use began intraoperatively, patients in group could 81 mg aspirin daily after surgery. first injection between twelve twenty-four...
To determine if differences in biomechanical properties and biochemical composition exist between human patellar articular cartilage the opposing femoral cartilage.The of 17 knees from 13 donors were determined for four sites on patella three femur representing regions contact at 30 degrees 90 flexion. The material by biphasic indentation testing, yielding compressive aggregate modulus, HA, permeability, k, Poisson's ratio, vs. thickness site, h, was also measured using a needle probe....
Background: Venous thromboembolic events, either deep venous thrombosis or pulmonary embolism, are important complications in patients undergoing knee hip arthroplasty. The purpose of this study was to evaluate the effectiveness a mobile compression device (ActiveCare+S.F.T.) with without aspirin compared current pharmacological protocols for prophylaxis against thromboembolism elective primary unilateral arthroplasty lower-extremity joint. Methods: A multicenter registry established capture...
Empirical clinical observation suggests that cigarette smoking had an inhibitory effect on long bone fracture healing, but this has not been proven scientifically. Forty female New Zealand White rabbits midshaft tibial osteotomies performed and plated. These were divided randomly into two groups receiving either systemic nicotine or saline (placebo). Lateral radiographs taken at 4, 6, 8 weeks showed a 17.2% average difference in callus formation between the significant lag of cortical...
Members of a consortium leading US health care systems, known as the High Value Healthcare Collaborative, used administrative data to examine differences in their delivery primary total knee replacement. The goal was identify opportunities improve value by increasing quality and reducing cost that procedure. study showed substantial variations across participating organizations surgery times, hospital lengths-of-stay, discharge dispositions, in-hospital complication rates. also revealed...
Unicompartmental medial knee arthritis can be successfully treated with either unicompartmental or total arthroplasty (UKA TKA). Active patients often inquire about the relative likelihood of returning to a sport-related activity after surgery. Some advocates UKA suggest that lead higher rate return sports postoperatively, but little information is available comparing outcomes versus TKA. We identified 33 and 39 TKA minimum 2-year follow-up (4 ± 1.2 years) who had similar preoperative...
Background Polyethylene liner dissociation is a rare but catastrophic event in total hip arthroplasty (THA), and certain implant designs are known to be at greater risk. Although the DePuy Pinnacle (Warsaw, IN, USA) modular acetabular construct has an excellent record of fixation wear, unexpectedly high number dissociations been noted. Questions/purposes The purposes this study were (1) characterize clinical parameters observed large group patients who have experienced with component; (2)...
Objective: To compare quantitatively the axial and torsional stiffness of a retrograde intramedullary nail fixed angle screw side plate in treating supracondylar femur fracture osteopenic femora. determine modes failure an under loading. Design: Matched pair cadaveric study. Setting: Orthopaedic biomechanics laboratory. Patients Other Participants: Eleven matched pairs preserved human femora were selected. The specimens harvested from relatively elderly donors with average age 75.6 years,...
Brachial plexus compressive neuropathy following the use of axillary crutches (crutch palsy) is a rare but well-recognized entity. Most reported cases involve posterior cord brachial in children and have resolved spontaneously within 8-12 weeks. We recently treated 36-year-old man who was using for mobilization after supracondylar femoral fracture. Bilateral (predominantly radial nerve) subsequently developed, with lesser involvement ulnar median nerves. The patient had little to no...
Tendonitis, tenosynovitis, and the arthritides are clinical problems commonly encountered in daily orthopaedic practice. Systemic anti-inflammatories, physical therapy, local corticosteroid injections all used as nonoperative treatments of these conditions. anti-inflammatory agents agents, however, can be associated with adverse effects that render them intolerable to some patients. As a preliminary study assessing feasibility injection nonsteroidal medication, histological biomechanical...
High-energy intra-articular fractures of the tibial plateau and plafond cause ongoing management problems for orthopedic surgeon. This study retrospectively evaluated 37 such treated with limited internal fixation circular frame external fixators. Seventeen (5 open) 20 (9 were treated. Time to union, number procedures, complications, functional outcomes evaluated. All healed within an average 3.8 months. Eighteen at 4.8 There was a high complication rate as is common these injuries, but most...
