Adverse local tissue reaction after ceramic-on-ceramic total hip arthroplasty.

We report a rare case of symptomatic adverse local tissue reaction in a patient with a ceramic-on-ceramic total hip bearing surface and review the literature. Probably, ceramic wear debris is not entirely inert and may lead to adverse local tissue reactions.

The Role of the Muscle Brachioradialis in Elbow Flexion: An Electromyographic Study.

Background: In the classical conception, the brachioradialis is a forearm supinator. The hypothesis of this study was that, at least in certain positions of elbow flexion and forearm rotation, the brachioradialis is, along with the biceps and brachialis, one of the main elbow flexors.

Methods: Fifteen young healthy male volunteers participated in this research.
