Abstract: A femoral hip prosthesis comprises a stem component generally divided into a proximal portion and a substantially longer distal portion. The stem has a slight posterior bow along its length. The proximal portion includes a slight twist of from about 5.degree. to 15.degree., the twist extending in a direction from the anterior to the posterior face of the stem through the medial face thereof. The characteristics of the stem provide a glove fit when inserted into a prepared intermedullary canal in the femur.
Abstract: A series of novel derivatives of penicillanic acid 1,1-dioxide, having a disubstituted methyl group of the formula X--CH--Y at the 6-position, and the pharmaceutically-acceptable salts thereof and the pharmaceutically-acceptable esters thereof readily hydrolyzable in vivo, wherein X is hydroxy, acylated hydroxy or amino and Y is carboxy or esterified carboxy. The compounds of the invention are inhibitors of bacterial beta-lactamases, and they will protect certain beta-lactamase-susceptible beta-lactam antibiotics, e.g. ampicillin, against inactivation by beta-lactamases. Co-administration of a compound of the invention with a beta-lactam antibiotic such as ampicillin to a mammalian subject increases the effectiveness of the beta-lactam antibiotic against infections caused by beta-lactamase-producing bacteria.

Abstract: A rasp handle has an elongate body portion with a pistol-type grip extending therefrom and rasp retaining structure at its front end. Such structure includes a fixed jaw and a slide jaw constructed and arranged for sliding movement relative to the fixed jaw between a forward closed locking position where a rasp is locked between the jaws and a rearward open rasp receiving and releasing position. A lever is connected to shift the slide jaw between its closed and open positions. A pivot interconnects the lever and the slide jaw so that the lever is free to move between a locked position adjacent the body portion and an unlocked jaw manipulating position away from the body portion.
