Tibiotalocalcaneal TTC arthrodesis with bulk femoral head allograft is a commonly performed limb salvage procedure when dealing with complex deformity.

. Femoral head shaft struts rings Femur. OUR MISSION For over 25 years weve continually advanced our processes and products. We describe a simple method of allograft preparation for this procedure as graft preparation and implantation can be time consuming and technically challenging.

The relative cost-effectiveness of this tissue as a source of allograft bone is discussed. Femoral and humeral heads designed to provide immediate structural support to restore segmental bone loss or to be ground into corticalcancellous chips. Studies show that osteochondral allografts transplanted within 15 to 28 days of recovery have significant functional and clinical advantages.

An allograft femoral head is thawed in a warm saline bath at the beginning of the procedure and placed in the bone vice Allogrip Bone Vise DePuy Warsaw IN with the three limbs of the vice gripping the femoral neck. Natural bone matrix facilitates cell attachment and proliferation and vascular in-growth. Reducing theatre preparation time.

One of the advantages of this type of allograft is its ability to preserve limb length 1 2 3 because of the structural strength of the femoral head. Our purpose is to describe a technique for wrist arthrodesis after failed total wrist arthroplasty utilizing fresh-frozen femoral head allograft and dorsal plate fixation. When using bone graft for this purpose most surgeons prefer to utilise femoral head allografts from living donors as this is a readily available graft is easy to work with and has good results in the orthopaedic literature 1.

Cortical wall provides immediate structural. Half - view product sheet PDF 119KB Half - view technical specification PDF 194KB. We have more options than those listed below and can review the available options and sizes with you.

Our tissue banks provide bone grafts for virtually every orthopedic podiatric and reconstructive operation. Please contact us for information on any graft you need. Mandelbaum MD demonstrates an autograft OATS 20 procedure to treat an articular cartilage defect in the knee and how the OATS 20 procedure can be used for transplantation of precut osteochondral allograft cores for the primary implant or to backfill the donor site.

The most common source of allograft is via the donation of the femoral head medical term for the part of the hip joint that is removed during hip replacement surgery. The female reamer corresponding to the same size male reamer used for reaming the defect is used to decorticate the allograft. Femoral Head Allograft Preparation The donor femoral head allograft is secured in the Arthrex Allograft OATS Workstation and perpendicular alignment is confirmed with the OATS sizer.

We present a case of femoral head chondroblastoma treated with a femoral neck trapdoor procedure and allograft. It has been freeze dried sterilized with gamma irradiation and has an approximate weight of 20g. The Allograft OATS donor harvester with a collared guide pin is attached to the drill passed into the proximal graft housing and rested on the grafts surface.

The average femoral head allograft is 54 to 56 mm in diameter and yields 50 cm 3 of bone graft with an average cost of US 435 for processing of the tissue resulting in a cost of US 870 per cm 3 of allograft produced. The femoral head allograft is used for resurfacing cartilage defects with mature hyaline cartilage. Provided stripped of cartilage and free from blood and lipids.

In this demonstration they outline the technique for an open surgical dislocation with a trochanteric osteotomy to gain access to the joint space. Guaranteed head diameter 48mm. We have also found the cup-in-cone interfaces achieved with use of the femoral.

Allograft Femoral and Humeral Heads SAL 10 -6 sterility. 3587 ALLOSOURCE ALLOGRAFT CATALOG Inspired by the gift of donation from our communities AlloSource responsibly provides innovative cellular and tissue allografts to advance patient healing. They provide an overview of the necessary steps to perform this procedure to replace the damaged cartilage of a lesion in the anterior superior region of the femoral head.

Distal portion of femur transected through the shaft incorporating both femoral condyles. The main treatments reported include acetabular osteotomies osteochondral grafts and vascularized fibular grafts. The femoral head has been processed to remove soft tissue cut in half longitudinally and washed to deplete cell and marrow content.

It was fashioned as a wedge with the cortical bone of the femoral head allograft aligned to the medial cortex of the tibia. The trapezoidal bone graft was cut according to the principles described by Noyes et al. The reported incidence of femoral head chondroblastoma is rare accounting for approximately 12 of bone tumors.

ALLOGRAFT CATALOG To order call 800. The femoral head allografts dimensions were determined by preoperative plans. RELATED ARTICLES PRODUCT SHEETS SURGICAL TECHNIQUES RELATED ALLOGRAFTS Features and Benefits.

Department of Energy Office of Scientific and Technical Information. However little has been reported in patients who receive tibiotalocalcaneal arthrodesis with femoral head allografts for a rigid cavovarus foot type. In our experience the use of frozen femoral head is an ideal structural allograft for the treatment of large bone deficits that require fusion.

If femoral head removed transected at femoral neck. Allograft OATS Technique Femoral Transplantation Using a Precut 16 mm OCA Core Bert R. Made available by US.
