Methylmethacrylate Metabolism in Man
Clinical Orthopaedics and Related Research, 1979Methylmethacrylate, the monomeric component of the polymethylmethacrylate cement used in orthopedic surgery, has been shown to undergo hydrolysis to methacrylic acid during hip replacement operations. Circulating levels of methacrylic acid were comparable with those of methylmethacrylate.

The hardnesses of poly(methylmethacrylate)
Tribology International, 1996The paper describes an experimental study of the normal and scratch hardnesses of a poly(methylmethacrylate). The deformations have been introduced using hard steel cones of a range of included cone angles. The influence of the state of interfacial lubrication is examined and rationalized.

The Effect of Methylmethacrylate on Fracture Healing
Clinical Orthopaedics and Related Research, 1976Fractures were created in the femur of dogs by dividing the midshaft with an airdriven saw. Immobilization was achieved with a four-hole compression plate. No methylmethacrylate supplementation was used in the control groups. In the three experimental groups methylmethacrylate was added to the internal fixation by placing it on the endosteal ...

Journal of Nanoscience and Nanotechnology, 2006
As most of polypeptides are marginally stable, a mild formulation procedure would be beneficial for the activities of these drugs. The objective of the present study was to develop a novel pH-sensitive nanoparticle system that was suitable for entrapment of hydrophilic insulin but without affecting its conformation.

Posterior Methylmethacrylate Fixation for Cervical Trauma
Spine, 1981Five cases of cervical instability after trauma were reviewed after being treated at other hospitals with posterior methylmethacrylate fixation. Three cases developed infections, and reduction was lost postoperatively in two other cases. A total of four re-operations was required.

Fixation of the Femoral Head Prosthesis With Methylmethacrylate
Clinical Orthopaedics and Related Research, 1975The techniques used in fixation of the femoral prosthesis in total hip replacement are often based on empiricism and raise questions about: venting the medullary canal with a catheter during the insertion of cement; the inclusion of blood into cement during insertion with possible deleterious effects; recementing a prosthesis; increased strength ...

Experimental fixation of fractures of the femur with methylmethacrylate
The Journal of Bone & Joint Surgery, 1975Use of a simple method for injection of cooled methylmethacrylate into the distal part of the femur through the canal of a Küntscher rod to stabilize distal femoral-shaft fractures proved experimentally to greatly increase the torsional stability at the fracture site.

Modelling of batch polymerization of Methylmethacrylate
1994Many acrylic and vinylic monomers are often polymerized by a free radical chain addition mechanism. This process consists of a three main steps: initiation, propagation and termination. Free radicals are formed by the fragmentation of the initiator, once formed these radicals propagate by reacting with monomers to form long macroradical chains.
