Infection risk prevention following total knee arthroplasty.

Introduction: Implant infection is serious; prevention is mandatory, and requires assessment.The present study assessed the incidence of deep surgical-site infection (SSI) at 1 year following total knee arthroplasty (TKA) and adherence to skin preparation, antibiotic prophylaxis,screening and prevention in case of methicillin-resistant S. aureus (MRSA).

The accuracy of free-hand cup positioning--a CT based measurement of cup placement in 105 total hip arthroplasties.

We studied 105 patients who received a total hip arthroplasty between June 1985 and August 2001 using freehand positioning of the acetabular cup. Using pelvic CT scan and the hip-plan module of SurgiGATE-System (Medivision, Oberdorf, Switzerland), we measured the angles of inclination and anteversion of the cup. Mean inclination angle was 45.

[Cup placement in hip replacement surgery -- A comparison of free-hand and computer assisted cup placement in total hip arthroplasty -- a multi-center study].

Aim: The purpose of the current study was to determine the accuracy of free hand and computer-assisted (CAS) cup placement.

Material And Methods: Between June 1985 and August 2001, 105 free-hand and from March to November 1999 80 total hip arthroplasties under computer assistance were implanted in the above mentioned centers. To determine the accuracy of the cups, the inclination and anteversion angles were measured.

A multicenter, randomized, double-blind, controlled trial of nebulized epinephrine in infants with acute bronchiolitis.

Background: The treatment of infants with bronchiolitis is largely supportive. The role of bronchodilators is controversial. Most studies of the use of bronchodilators have enrolled small numbers of subjects and have examined only short-term outcomes, such as clinical scores.

Reduction in variability of acetabular cup abduction using computer assisted surgery: a prospective and randomized study.

Optimal orientation of the acetabular component of a total hip prosthesis is an important factor in determining the early and long-term result of a total hip arthroplasty (THA). Conventional positioning of the cup component is usually done using a free-hand method, or with the help of a mechanical acetabular alignment guide. However, these methods have proven to be inaccurate, and a great variation in orientation of the cup is found postoperatively.
