Abstract: An expandable wedge implant for wedge osteotomies of the extremities has first and second components which are pivotally attached to each other such that up and down pivoting of the two components relative to one another causes increase and decrease of implant height. A pivot control structure is operably coupled to and between the two components to effect pivoting. Linear movement of a threaded ball on a threaded shaft associated with the first component while the threaded ball is concurrently constrained within an angled channel of the second component causes pivoting of the second component relative to the first component. Anchoring members associated with the first and second components attach the implant to adjacent vertebral bodies.

Abstract: A medical device, i.e., an acetabular surgical implant, for a segmental acetabular defect with pelvic discontinuity that is installable and fully functional without any need for any intermediary implant such as a surgical cage or a surgical shell. The surgical implant includes a hemispherical cup with a plurality of equidistant apertures extending through the cup, and a ribbed, elongated stress-diffusion element, i.e., a stem, extending from the cup. The stem is formed to extend from and be oriented with respect to the cup based on whether the surgical implant is to be used on a left side of the patient, i.e., a left acetabulum, or a right side of the patient, i.e., a right acetabulum, for reconstruction of the segmental acetabular defect.

Abstract: When using an artificial knee joint replacement operation instrument, the amount of labor required to attach a tibial insert trial to a patient is further reduced.

The tibial trial attachment instrument assembly includes a template to be attached to a tibia, a keel punch guide to be joined to the tibia via the template, a keel punch to be inserted into the tibia through the keel punch guide, a keel punch handle for operating the keel punch, and a tibial insert trial to be placed on the template, the tibial insert trial being separate from the template.

Abstract: A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.
