Distal femoral replacement with allograft/prosthetic reconstruction for treatment of supracondylar fractures in patients with total knee arthroplasty.

Large-segment distal femoral allografts were used in conjunction with non-linked total knee prostheses to reconstruct bone deficits following supracondylar fracture of the femur in seven patients with previous total knee arthroplasties. Three patients with multiple medical problems died of unrelated causes prior to a minimum 2 year follow-up. Indications for surgery were previously failed attempts at osteosynthesis and significant fracture comminution, osteopenia, and intercondylar extension or femoral component loosening.

Custom total shoulder arthroplasty in inflammatory arthritis. Preliminary results.

Twenty-three patients with inflammatory arthritis and rotator cuff deficiency have undergone 27 custom-fit total shoulder arthroplasties. The design used included a short-stem humeral component and a metal-backed glenoid component with an offset keel. The glenoid component was custom-fit to provide maximum coverage of the glenoid surface.

Use of an antibiotic impregnated polymethyl methacrylate intramedullary spacer for complicated revision total hip arthroplasty.

Revision total hip arthroplasty is frequently necessary in the presence of significant proximal femoral bone loss, periprosthetic fracture, or infection. In these situations, optimal reconstruction may sometimes warrant the use of special implants, including bone grafts. The emergent presentation of these cases or unexpected findings at the time of surgery can preclude the use of these treatment options.

"Hybrid" total knee arthroplasty with the Miller-Galante prosthesis. A prospective clinical and roentgenographic evaluation.

Twenty-nine "hybrid" Miller-Galante total knee arthroplasties, in 22 patients, were evaluated prospectively and according to the clinical and roentgenographic guidelines of The Knee Society. Selection of this technique, incorporating an uncemented, porous-ingrowth femoral component and a cemented tibial component, was based on patient age, medical condition, activity level, and intraoperative assessment of bone quality and ligament competency. The average age of the patients at the time of surgery was 71 years.
