Dislocation of a McMinn-Like Prosthesis with Distinctive Metallosis and Fracture of the Os Ilium.

Osteoarthritis of the hip joint (coxarthrosis) is the most common hip disease in adults. Since the 1960s, total hip arthroplasty (THA) has made great progress and is nowadays one of the most frequently used procedures in orthopedic surgery. Different bearing concepts exist in various implant designs.

[Manual addition of antibiotics to industrial bone cement mixes : Investigations of the dry mix in the cement cartridge during manual admixture to polymer-active substance mixtures].

Background: Periprosthetic infection (PPI) is a rare but serious complication. An elementary component of the therapy of PPI is the use of bone cement with the addition of antibiotics. For targeted therapy, manual mixing of antibiotics with industrially produced bone cement mixtures is often necessary.

Toward a Bidirectional Communication Between Retinal Cells and a Prosthetic Device - A Proof of Concept.

Significant progress toward the recovery of useful vision in blind patients with severe degenerative retinal diseases caused by photoreceptor death has been achieved with the development of visual prostheses that stimulate the retina electrically. However, currently used prostheses do not provide feedback about the retinal activity before and upon stimulation and do not adjust to changes during the remodeling processes in the retina. Both features are desirable to improve the efficiency of the electrical stimulation (ES) therapy offered by these devices.

One stage conversion of an infected fused knee to total knee replacement - a surgical challenge.

Background And Purpose: Two-stage revision arthroplasty is a common technique for the treatment of infected total knee replacement. Few reports have addressed the conversion of a fused knee into a total knee replacement. However, there is no case reported of converting an infected fused knee into a hinge knee using a one-stage procedure.

Optimizing ceftazidime pharmacodynamics in patients with acute exacerbation of severe chronic bronchitis.

Objectives: Implementation of current pharmacodynamic knowledge could enhance clinical results, avoid resistance development and reduce treatment costs. In this open, randomized, multicentre study, we evaluated the clinical and bacteriological outcome and pharmacokinetic as well as pharmacodynamic parameters of two ceftazidime therapy regimens in patients with acute exacerbation of severe chronic bronchitis (AECB).

Methods: Eighty-one patients (56 males, 25 females, age 65.
