Abstract: A femoral orthopaedic prosthesis includes a metallic core extending from a proximal end to a distal tip. The metallic core includes a neck that is positioned at the proximal end and is configured to receive a prosthetic femoral ball. An elongated stem extends distally from the neck to the distal tip. The stem includes a proximal section extending distally from the neck, and a distal section that extends proximally from the distal tip. The elongated stem also includes a pair of spaced-apart beams that connect the proximal section to the distal section. An aperture is defined in the stem between the pair of spaced apart beams.

Abstract: An acetabular shell component includes a solid substrate, a porous outer layer coupled to the solid substrate, a porous inner layer coupled to the solid substrate, and an inner bearing coupled to the porous inner layer. One or more adjuncts extend outward from the porous outer layer. Each adjunct includes an outer surface that defines a customized patient-specific negative contour shaped to conform to a positive contour of a patient's bone. A method for manufacturing the acetabular shell component using an additive manufacturing process is also disclosed.

Abstract: An impaction handle for use during a surgical procedure to implant a tibial tray into a surgically-prepared proximal end of a tibia includes an impact plate defining a proximal end of the impaction handle and an impact head defining a distal end of the impaction handle. The impaction handle also has an elongated shaft extending between the impact plate and the impact head, along with a locking mechanism to lock the handle to the tibial tray. The impact plate, the impact head, the elongated shaft, and the locking mechanism of the impaction handle collectively define a single monolithic metallic component.

Abstract: A bone saw cutting guide block includes a body and a bone saw guide assembly. The body includes a proximal surface and a distal surface. The bone saw guide assembly includes a first guide slot defined by the body. The first guide slot extends through the proximal surface and the distal surface along an insertion and retraction path. The first guide slot may accommodate lateral movement of a bone saw while guiding the bone saw along the insertion and retraction path. The first guide slot includes a first interior surface and a second interior surface. The first interior surface is spaced a first distance transversely away from the insertion and retraction path. The second interior surface is spaced a second distance transversely away from the insertion and retraction path. The first distance is smaller than the second distance.

Abstract: A three-dimensionally printed capsule includes a sintered exterior and an unsintered powder, both formed from a first powder supply. The sintered exterior defines an interior portion that hoses the unsintered powder. The sintered extern includes a base and a removable cap. The removable cap can transition between a fixed position and a detached position. The interior portion is sealed relative to the external environment in the fixed position, while the interior portion is exposed to the external environment in the detached position. The unsintered powder is protected from the external environment when the removable cap is in the fixed position. The unsintered powder is exposed to the external environment when the removeable cap is in the detached position.
