摘要： According to various embodiments, provided is a prosthesis system for replacement of a head portion of a proximal radius. The system can include a first polymeric articulation component having a first locking portion and a metal head component having a second locking portion. The second locking portion can mate with the first locking portion to form a first locking mechanism to initially couple the first articulation component to the head component. The head component can define a locking channel. The system can also include a stem component having a protrusion receivable in the locking channel. The protrusion can define a bore, and the stem component can be adapted to be coupled to the radius. The system can also include a fastener received through the locking channel and into the bore to provide a second locking mechanism that couples the head component to the stem component.

摘要： An elbow prosthesis can include a capitellar implant that has an articulating head and a stem. The articulating head can have a first substantially hemispherical portion and a second portion that collectively extend between lateral and medial sides of the articulating head and are separated by a plane. The first and second portions can generally extend between the lateral and medial sides. The second portion can generally have an attachment lobe that extends on the lateral side and that defines a passage therethrough. The passage can extend at least partially on the second portion.

摘要： An instrument for internal bone fracture fixation includes a shaft having a distal portion and a patient-specific bone holder coupled to the distal portion. The bone holder has a three-dimensional curved and patient-specific bone engagement surface designed during a preoperative plan based on a medical scan of a patient to match and conform to an outer surface of a bone fragment of the patient in only one position.

摘要： An elbow prosthesis constructed in accordance to one example of the present teachings can include a first stem structure that is operable to be positioned in a first bone of a joint. The first stem structure can include a first stem portion and a cage structure. The first stem portion may be operable to be positioned in the first bone. The cage structure can be formed generally between an inner sidewall and an outer surface. The stem portion can have opposing surfaces that define a disconnect formed entirely through the cage structure from the inner sidewall to the outer surface. A first bearing component can have an exterior cage opposing surface. The first bearing component can be selectively inserted into the cage structure from an insertion position to an installed position. A fastener can be threadably advanced into an engaged position with the cage structure to reduce a gap defined between the opposing surfaces of the disconnect while radially contracting the cage structure around the first bearing.
