摘要:
A shoulder prosthesis includes a vault-filling component defining a bearing-facing surface and having a first coupling component, the vault-filling component including (i) a vault-filling first portion defining a first part of the bearing-facing surface, and (ii) a projecting second portion projecting from the vault-filling first portion so as to define a second part of the bearing-facing surface. The vault-filling first portion and the projecting second portion define a bone space therebetween. The shoulder prosthesis further includes a bearing component defining a bearing surface and having a second coupling component configured to cooperate with the first coupling component to couple the bearing component to the vault-filling component. At least one bone attachment member positioned in the bone space. The projecting second portion of the vault-filling component further defines a scapula-facing surface.

A kit for use in performing joint arthroplasty on a head of a long bone is disclosed. The kit includes: a first implant including a first implant articulating surface and an opposed first implant mounting surface having a first implant location feature; and an instrument for preparing a cavity in the head of the long bone. The instrument includes a body and a punch extending from the body. The punch includes a portion thereof having a shape similar to the first implant location surface of the implant. A method for providing joint arthroplasty is also disclosed.
摘要:
An instrument(10) for use in performing arthroplasty is provided. The instrument(10) includes a first portion(11) adapted to prepare a convex surface(64) on the head(5) of the long bone(4). The instrument (10) also includes a second portion (13) adapted to prepare an elongated cavity (62) or a third portion (14) adapted to prepare a central support surface (56) on the head (5) of the long bone (4), or both second portion (13) and the third portion (14). The third portion (14) and the second portion (13) are operably associated with the first portion(11).

The vault-filling first portion of the vault-filling component further defines (i) a first lateral surface extending from the scapula-facing surface, and (ii) a second lateral surface extending from the first part of the bearing-facing surface. The first lateral surface and the second lateral surface taper towards each other in a direction extending away from the bearing-facing surface.

A method for providing joint arthroplasty includes providing a gauge for making a measurement of the contour of a long bone, making a measurement of the contour of a long bone with the gauge, providing a plurality of joint prostheses, selecting one of the plurality of joint prostheses based upon the measurement of the contour, resecting a long bone, and implanting the selected one prosthesis onto the long bone. A kit is also provided for selecting one of a plurality of joint implants for use in joint arthroplasty on a bone. The kit includes a first gauge and a second gauge.

A kit (100) for use in performing joint arthroplasty on a head of a long bone (4) is provided. The kit (100) includes a first trial (102) including a first trial articulating surface (106) and an opposed first trial mounting surface (108) having a first trial location feature (110). The kit (100) also includes a second trial (104) including a second trial articulating surface (112) and an opposed second trial mounting surface (114) having a second trial location feature (116). The first trial articulating surface (106) and the second trial articulating surface (112) have different geometries and the first trial location feature (110) and the second trial location feature (116) have substantially identical geometries whereby different trials may be used with a common location feature.

摘要:
A prosthesis for attachment to the proximal humerus of a patient during a shoulder arthroplasty has a cup and a spacer. The cup has an articulation surface and an internal surface opposed to the articulation surface. At least a portion of the internal surface is concave. The spacer has a support surface and an opposed surface. The support surface is configured for intimate contact with the proximal humerus and the opposed surface is configured for assembly to the internal surface of the cup.
摘要:
A gauge (10) for measuring bone contour (12) of a bone(4) for use in joint arthroplasty is provided. The gauge (10) includes a body (14) and a probe (16). The body (14) has a body contact portion of the body (14) for contact with the bone (4). The probe (16) is movably positional with respect to the body (14). The probe (16) includes a probe contact portion of the probe (16) for contact with the bone (4). The relative position of the probe (16) with respect to the body (14) is indicative of the bone contour (12) of the bone (4).
