Abstract: In the method of performing a modified intervastus approach in total knee arthroplasty procedures, a straight incision is initially made in a patient's knee. The incision is located medial to a midline of the patient's knee, in line with the medial border of the tibial tubercle distally extending proximal to the patient's patella. Fascia overlying a lateral edge of the patient's vastus medialis is then incised at a point where the patient's vastus medialis meets the patient's quadriceps tendon. The patient's vastus medialis is separated from the patient's quadriceps tendon and the patient's vastus medialis is elevated off of an underlying capsule. The underlying capsule is incised from a cephalad end to a caudal end thereof, extending medial to the patient's patella.

Abstract: The invention relates to a prosthesis for implantation into a long bone during joint arthroplasty, particularly Total Shoulder Arthoplasty and Total Hip Arthroplasty, and a method for use of the implant.

Abstract: The implantable prosthesis for replacing a human knee joint comprises a femoral prosthetic element (12) and a tibial prosthetic element (14) which are articulated with one another by means of a joint device (30) for the purpose of executing a knee bend. The tibial prosthetic element (14) has a through-opening (40) for the passage of a tool (84), a rod-like shaft anchoring part (32) or an intramedullary lengthening nail (80).

Abstract: A device and method of manufacturing and implanting a custom subtalar arthroereisis implant having side surfaces which are mirrored in topography with the sinus tarsi of a patient. The implant is formed using images of the patient standing in a weight bearing position with their sinus tarsi and the surrounding bone structure in an anatomically correct alignment. Once implanted, the implant urges and maintains the anatomically correct alignment thereby minimizing any patient tendency for abnormal motion between said patent's talus and calcaneus.

Abstract: A branched stent graft, a convey system comprising thereof and manufacturing method thereof, the branched stent graft includes a main body (100) and a side branch (200), at least a portion of a lowermost stent section of the side branch (200) closest to the main body (100) is not stitched to the cover of the side branch from a lower end to an upper end, the at least a portion of the lowermost stent section is located on a side of the side branch corresponding to a folding direction of the side branch. After deployed, the branched stent graft has an effective supporting force at the base portion of the side branch. In addition, during the deployment of the stent, the side branch can expand to a maximal extent even when the positioning is slightly inaccurate. Further, vascular stenosis or occlusion will not be caused even when subsequent endothelialization occurs.

Abstract: An instrument for assembling an implant on a neck. The implant and neck being coupled via a taper having a taper axis. The instrument includes a frame having a distal portion and a proximal portion, the distal portion of the frame including a retaining member adapted to engage a portion of the neck. The retaining member includes a pair of moveable arms extending from the distal portion of the frame, the pair of moveable arms adapted to engage a pair of recesses on opposing sides of the neck. The instrument also includes a force applier retained in the proximal portion of the frame. The force applier includes a screw having a screw axis that is coaxial with the taper axis, wherein the screw is adapted to engage the implant. As the screw is turned, the force applier applies a force on the implant while the neck is held in place by the frame, thereby causing the tapers of the implant and neck to engage.
