From Which Medical Device

The OsteoMed Bio-Action Great Toe System is designed for arthritis of the first metatarsophalangeal joint. It consists of two cemented components which are offered in two sizes and in neutral, right and left configurations. The instruments include broaches, impactors, awl, drill guides and preparation instruments.

In a series of 48 patients, the functional results at five years were satisfactory.1 Another smaller series of 15 patients demonstrated high rates of loosening at five years however.2
