Two semicylindrical bodies, each mounted on a respective end of one member of a pair of pivotally interconnected blades, are closed to form a cylindrical body having a first end in which a frustoconical surface is arranged to guide a wire into a central bore, and a second end communicating with bore and in which a semi-spherical cavity is shaped to receive a bone end. The wire insertion guide is particularly applicable to procedures such as resectional arthroplasties requiring K-wire fixation, Hoffman-Clayton type rheumatoid forefoot reconstructive procedures, and procedures relating to finger reconstruction.

An expandable subtalar implant device suitable for addressing a flatfoot condition. The device is a sinus tarsi implant that blocks excessive motion between the talus and calcaneus bones in the foot while permitting normal motion and alignment. The device comprises a generally cylindrical metal structure having a first proximal expandable end and a second distal adjustment end. A first component of the implant forms each of the cylindrical end sections and a second component comprises a movable internal rod that serves to progressively expand the outer cylinder of the implant. The internal rod is externally threaded and mates with internal threading on the cylindrical outer component. Progressive turning of the internal rod engages a number of radially arranged inclined surfaces that form the interior walls of the cylindrical shell component. Progressive engagement of the rod with these inclined surfaces forces the end of the cylindrical shell component outward; expanding the overall diameter of the implant once it has been positioned within the sinus tarsi.

An improved implant for use primarily within the first metatarsophalangeal joint. The implant includes an elliptical, concave, joint surface positioned on a stem and is designed to be placed into a prepared proximal face of the phalanx. The implant is sized according to the patient and may be provided in a number of standard incremental sizes. The improvements relate primarily to the structure, size, and position of the stem that extends into the phalanx to support the implant. The stem is off-set from a center axis of the elliptical joint surface. This off-center placement allows for a longer stem. Single deep indentations on each side of the stem facilitate retention within the bone. A size selection tool is provided to facilitate the selection and placement of an appropriately sized implant. The tool further provides a template for positioning and placing the stem in the phalanx. A method for sizing and selecting the appropriate implant, and positioning and fixing the implant as a partial joint replacement, especially for the first metatarsophalangeal joint, is also described.

A surgical scalpel having multiple cutting segments designed especially for podiatric surgical procedures is disclosed. More particularly, the scalpel blade has a handle attachment section and a number of cutting segments. The blade includes a single-edged longitudinal cutting segment extending from the handle attachment section, a single-edged curved cutting segment contiguous with the longitudinal cutting segment, and a double-edged end tip cutting segment contiguous with the curved cutting segment. The double-edged end tip cutting segment may be designed in varying degrees of curvature, including semi-circular and semi-elliptical. Multiple cutting edges are contained on one scalpel blade for optimum flexibility, efficiency, and economy.

An apparatus and method for retrieval of fractured cannulated screws used for bone fixation. The retractor comprises a retraction shaft having a proximal end and a distal end, a tool shaft connected to the proximal end, a body having a reverse helix connected to the distal end, and a feeler shaft having a point connected to the body.

An osteotomy guide apparatus for assisting in the conduct of Chevron, Youngswick, and Reverdin osteotomy procedures. The osteotomy guide comprises a first and second saw slot converging at an apex. The apparatus further comprises a multiplicity of bone pin holes to firmly fix the osteotomy guide in place and optionally, a visualizer element to indicate to the surgeon the amount of correction which may be expected from the procedure before actual bone cuts are made. The guide may also comprise a first and second stage body which operate in a cooperative fashion to increase the amount of correction and stability provided by any given procedure.
