Abstract: A guide device for the placement of a bone screws or pin in the orthopedic treatment of bone fractures is disclosed. The guide device is constructed of a body having one or more tunnels for guiding therethrough an orthopedic pin for placement in the orthopedic treatment of a bone fracture. The body includes at least one frangible portion for separating the body from about the pin such that the body is removable while the pin remains in secured place within the bone.

Abstract: The invention contemplates integration of electrical componentry into an orthopedic cast, using one or more multiple-twin coils which are essentially flat and thin and flexibly conformable to local curvature of the limb or other body feature to be subjected to electromagnetic therapy. The coil or coils structure is devised for self-retention to the afflicted part of the body, for at least such time as is needed by the orthopedic surgeon to apply a supporting cast to the afflicted region, the coil or coils being a rigid ultimately expendible part of the cast. Provision is made for rigid cast support of an externally accessible electrical connector for excitation of the coil or coils with electrical signals having therapeutically beneficial coupling to the afflicted region, via induction from magnetic-field radiation by the coil or coils.
