A system for preparing an implant for implantation includes a trial implant including a first dialable component and a datum, a final implant including a second dialable component, and an instrument including (i) a base assembly configured to support the trial implant so that the datum is in a predetermined orientation, (ii) a fixture supported on the base assembly, the fixture including a domed element, and an alignment tool configured to engage the first dialable component when the trial implant is supported by said base assembly, and (iii) a locking assembly including a guide member defining a spherical surface for nested engagement with said domed element, the locking assembly configured to record the angular orientation of said alignment tool relative to said fixture with said alignment tool engaged with the first dialable component, and to replicate the recorded angular orientation with the alignment tool and a second dialable component.

Instrumentation for recording and replicating orthopaedic implant orientation

An instrument for recording or replicating the orientation of an adjustable component of an implant with respect to a stem portion of the implant includes a base assembly configured to clamp the stem portion of the implant in a predetermined orientation, and a fixture supported on the base assembly in a predetermined orientation with respect to the base assembly, the fixture including a locking assembly configured to be adjusted in three dimensions and locked in a configuration which angularly locks an alignment tool relative to the fixture in the three dimensions when the alignment tool is engaged with the adjustable component and the adjustable component is operably assembled with the stem portion and the stem portion is clamped by the base assembly.

An instrument for recording and replicating the spatial orientation of a dialable component of an implant relative to a bone engaging component of the implant includes a base assembly configured to support the trial implant so that the datum is in a predetermined orientation, a fixture supported on said base assembly, said fixture including an alignment tool configured to engage the first dialable component of the trial implant when the trial implant is supported by said base assembly, and a locking assembly configured to record the angular orientation of said alignment tool relative to said fixture with said alignment tool engaged with the first dialable component, and to replicate the recorded angular orientation with the alignment tool and a second dialable component.

An instrument for recording and replicating the spatial orientation of a dialable component of an implant relative to a bone engaging component of the implant includes a base assembly for supporting the bone engaging component and a fixture supported on the base assembly for supporting an alignment tool. The alignment tool is configured to engage a portion of the dialable component when the implant is supported by the base assembly. The fixture includes a locking assembly for locking the spatial position of the alignment tool relative to a pre-determined datum on a trial implant. The same instrument can be used to support a final implant and to replicate the spatial position of the alignment tool relative to the same datum on the final implant. The alignment tool can then be used to align the dialable component of the implant. The alignment tool can also constitute an impacting tool so that it can be used to impact the dialable component into locking engagement with the implant using the same instrument.

A surgical garment includes a head gear apparatus for supporting a face shield and shroud. The head gear apparatus includes a helmet that supports a fan assembly, and that defines forward and rear ventilation passageways. The helmet includes a chin bar that defines a centrally located slot, and an upper ledge. The upper edge of the face shield contacts the upper ledge, while the lower edge of the shield includes a tab that extends through the slot. The chin bar and face shield include a plurality of magnetic elements that magnetically connect the lower edge of the face shield to the chin bar. The helmet is suspended from a strap assembly that is carried directly on the head of the wearer. The strap assembly includes an adjustable occipital support that bears against the occiput of the wearer. The face shield can include a plurality of film layers that can be removed when soiled. The fan assembly includes an inlet opening and the shroud includes a filter assembly that is sized to overlay the inlet opening and a portion of the helmet surrounding the inlet opening.
