INTRODUCTION: Polyethylene wear is a recurrent problem in joint arthroplasty. In addition to permanent deformation or complete destruction of the component, small debris particles are also associated to inflammation reaction of the surrounding bone, eventually leading to the failure of the bound between the implant and the host bone, and implant loosening. In anatomic total shoulder arthroplast...

OBJECTIVE Increasing evidence suggests that smoking may increase the incidence of prosthesis-related complications after total hip arthroplasty (THA). We performed a meta-analysis of cohort studies to quantitatively evaluate the association between smoking and the risk of prosthesis-related complications after THA. METHODS Relevant articles published before August 15, 2014, were identified by...

Statement of problem: There is little information about the maintenance requirements of implant restorations. Purpose: To compare the prosthodontic maintenance requirements of screw-retained implant prosthesis versus that of telescopic overdentures after an observation period of 18 months. Materials and methods: 26 completely edentulous patients were enrolled in the study. Patients were divided...

BACKGROUND AND PURPOSE After joint replacement, a repair process starts at the interface between bone and cement. If this process is disturbed, the prosthesis may never become rigidly fixed to the bone, leading to migration-and with time, loosening. Cox-2 inhibitors are widely used as postoperative analgesics, and have adverse effects on bone healing. This could tamper prosthesis fixation. We i...

The purpose of this study was to evaluate the results of the Universal Total Wrist prosthesis. Seventeen wrist arthroplasties were performed in 15 patients using the Universal Total Wrist prosthesis. The 11 women and 4 men in the study group ranged in age from 45 to 86 years. Fourteen patients had rheumatoid arthritis and one had osteoarthritis. Follow up ranged from 20 to 74 months. Patients w...

We report the case of a patient who underwent explantation of a Maverick total disc prosthesis at the L5S1 level because of severe persisting pain one year after initial implantation. Dynamic radiographic imaging studies showed good position and size of the prosthesis and no evidence of loosening. Intraoperatively residual mobility at the proximal bone-prosthesis interface was detected, as well...

BACKGROUND We studied which factor could predict aseptic loosening in ABG I hip prosthesis with hydroxyapatite coating. Aseptic loosening and periprosthetic osteolysis are believed to be caused, at least in part, by increased polyethylene (PE) wear rate via particle disease. Based on it, increased PE wear rate should be associated with aseptic loosening regardless of the type of implant. METH...

PURPOSE To compare mid-term outcomes of a high-flexion prosthesis with a conventional prosthesis. METHODS Records of 107 consecutive patients who underwent total knee arthroplasty (TKA) for primary osteoarthritis by a single surgeon were reviewed. 21 men and 36 women (mean age, 65 years) used a high-flexion prosthesis (NexGen CR-Flex Mobile, Zimmer), whereas 38 men and 12 women (mean age, 67 ...
