The concentration of methylmethacrylate monomer (MMA) in the blood stream after implantation of the components of 15 total hip prostheses using bone cement was determined in the pulmonary artery, the radial artery, and the superior vena cava after cement application, and correlated with the observed

β¦ Synopsis
Extensive localized bone lysis in the femur following implantation of a metal-on-metal total hip prosthesis was observed. Fragmentation of the cement occurred 10 years after implantation. Histologic and ultrastructural features of macrophages are consistent with the hypothesis that particles from the acrylic resin were the factors stimulating the macrophagic reaction. Both mechanical factors and changes of the physico-chemical properties of the cement may have an etiologic role.

Thirteen failed stem of Total Hip Replacement were studied: 9 were Charnley THR from an homogeneous series, which gives an incidence of 2.4% of stem fractures with a follow-up of 9-16 years; 4 were Mueller THR.

## Objective: To determine whether provider volume is associated with early failures following total hip replacement (thr) requiring revision. ## Methods: Claims data were analyzed to follow a cohort of 57,488 medicare beneficiaries who underwent elective primary thr in 1995-1996 in 3,044 hospita
## Abstract Through a survey of hip replacement arthroplasty the paper establishes the case for objective evaluation of these joints in the patient. It then outlines a simple, nonβinvasive technique, based on Paul's (1967) locomotion studies, to assess preβ and postoperative functional capability.
Largely through the pioneering advances made by John Charnley,' total joint replacements with man-made metal and plastic materials have revolutionized the surgical treatment of millions of patients with end-stage hip and knee arthritis for the past 30 years. Approximately 500,000 total hip and knee
