摘要:
An apparatus and method is disclosed for performing a surgery, such as an orthopedic surgery. The apparatus can include a guide portion and an alignment portion. The guide portion can assist in positioning the alignment portion to assist in aligning an implant. The implant can be aligned and positioned to hold a graft relative to a bone portion.

A fixation device for securing tissue to a bone. The fixation device includes an anchor having a hollow body defining a longitudinal passage, and a plug configured to be received in at least a portion of the passage. The body comprises a cylindrical portion and a tapered tip portion. The cylindrical portion comprises a plurality of thin-walled window covers such that after implantation the window covers are resorbed first relative to other portions of the cylindrical portion for defining a plurality of apertures on the cylindrical portion.

An apparatus and method for performing a surgery, especially an ACL replacement surgery, where a flexible strand insertion rod co-operates with a U-Guide apparatus to insert a flexible strand into a tunnel formed in a bone portion and to guide a pair of drill points to form a pair of tunnels transversely to the tunnel of the insertion rod. The drill points are guided through the insertion rod and the flexible strand is held over the drill points as the transverse tunnels are formed. The insertion rod is then removed from the tunnels formed in the bone and the flexible strand is held looped over the second drill point. Subsequently, a soft tissue replacement is affixed to one end of the flexible strand and pulled over up to the first drill point with the other end of the flexible strand. The first drill point is then used to pull a cross pin through the transverse tunnel to hold the looped end of the soft tissue replacement in place. Finally, the two free ends of the soft tissue replacement are affixed to the bone completing the implantation of a soft tissue replacement.
摘要:
An system and method for performing a surgery, such as an anterior-cruciate-ligament replacement surgery, where a flexible strand insertion rod can co-operate with a U-Guide apparatus to insert a flexible strand into a tunnel formed in a bone portion. A soft tissue replacement can be affixed to one end of the flexible strand and pulled over a retaining member with the other end of the flexible strand.

摘要:
A trial system for a prosthesis is described. The prosthesis can include an acetabular prosthesis generally for implantation in an acetabulum and the surrounding pelvis. The acetabular prosthesis includes an acetabular cup having a substantially concave inner surface and a substantially convex outer surface. One trial shell or a collection of trial shells are provided to trial a range of motion of the hip joint before implanting a shell prosthesis into the acetabular prosthesis.
摘要:
A method of forming an implant having a porous region replicated from scanned bone, the method comprising imaging bone with a high resolution digital scanner to generate a three-dimensional design model of the bone; removing a three-dimensional section from the design model; fabricating a porous region on a digital representation of the implant by replacing a solid portion of the digital implant with the section removed from the digital representation; and using an additive manufacturing technique to create a physical implant including the fabricated porous region.
摘要:
An acetabular cup assembly can include a cup portion and a bearing. The cup portion can include a porous metal outer layer having a first thickness and a solid titanium inner layer having a second thickness. A mating feature can be formed between the cup portion and the bearing. The bearing can be adapted to be selectively secured to the titanium inner layer. In one example, the bearing is formed of cobalt.
