    摘要: A modular trial neck segment is utilized for trialing a hip prosthesis for a total hip arthroplasty. The modular trial neck segment is preferably, but not necessarily, utilized for trialing a hip prosthesis for a total hip arthroplasty. The trial neck segment includes a mount attachable to a stem or broach, and a neck that is translatable on the mount for providing various neck offsets with respect to the mount and/or broach. Neck offset is changed via movement of the neck in a single plane of motion. This facilitates the use of the subject invention in minimally invasive arthroplasty wherein working dimensions are small. The present design replicates the biomechanics of the neck region of the implant. The mount and slidable neck provide a plurality of neck offsets and/or neck lengths for trialing a final prosthesis in a single device.

    摘要: The present teachings provide an ulnar head implant. The implant can include a head component adapted to articulate with a portion of the anatomy. The head component can define a coupling bore through a surface. The implant can also include a stem component having a base and a post that extends from the base for insertion into a prepared portion of an anatomy. The base can include a coupling feature. The implant can include an intermediate component receivable within the coupling bore and couplable to the coupling feature to couple the head component to the stem component.

    摘要: A modular proximal interphalangeal joint implant assembly including a first stem component, a second stem component, and an articulation assembly. The first stem component includes a first locking device and is operable to be implanted in a proximal phalanx bone. The second stem component includes a second locking device and is operable to be implanted in a middle phalanx bone. The articulation assembly includes a first articulation component operable to be removably attached to the first locking device and a second articulation component operable to be removably attached to the second locking device. The articulation assembly can include a semi-constrained articulation assembly or a constrained articulation assembly.
