In hip revision surgery, femoral head allografts can be used to manage bone loss in the acetabulum. Surgeons sculpt these allografts to fit the patient’s specific bone defect, before securing them into place. Once implanted, the allograft acts as a scaffold to promote new bone growth, helping to restore the original anatomy. These allografts also provide a robust and stable support for the new acetabular implant, thereby improving the long-term outcome of the surgery by enhancing joint stability and function.

Fibula allografting can be used to treat Osteonecrosis of the Femoral Head (ONFH) in its early stages, which, if left untreated, can cause severe hip dysfunction and may eventually lead to femoral head collapse and the need for total hip arthroplasty (THA). Fibular allografting involves taking a portion of the fibular shaft, and transplanting it into the necrotic area of the femoral head. This transplanted bone can provide structural support to the affected area.

Periprosthetic fractures are fractures that occur around joint replacements. Onlay allograft struts can be used in the management of these challenging fractures, providing
structural support to the fracture site and aiding in the bone healing process.

Pelvic osteotomy procedures, such as Pemberton or Periacetabular osteotomy, are often used in the treatment of hip dysplasia, a condition where the hip socket does not fully cover the ball portion of the upper thighbone. This results in an increased risk of hip dislocation. The use of an allograft bone wedge can be a part of this surgical procedure, helping to reorient the hip socket for better coverage of the femoral head.

Limb salvage procedures are a series of surgical treatments aimed at saving a limb that is at high risk of amputation. Sometimes, a section of bone needs to be removed due to infection (osteomyelitis) or a bone tumor. Once the diseased bone is removed, the bone shaft allograft can be used to fill the gap. It is carefully aligned and fixed into place. Over time, the patient’s own bone may gradually incorporate the allograft.

Allograft bone shafts can be utilized in joint arthrodesis procedures, which involve fusing two adjacent bones to stabilize a joint. This procedure is typically reserved for conditions where joint replacement is not an option or has failed, or when the joint’s function is severely compromised due to arthritis, injury, or disease. The allograft shaft can be used to promote fusion and provide stability in joints such as the ankle, wrist, or spine.

In revision joint replacement surgeries, such as hip, knee, and shoulder replacements, structural allografts can be used to fill in areas of significant bone loss around the joint. This is particularly important when previous implants have loosened or failed and caused damage to the surrounding bone. The grafts can help provide a stable platform for the placement of the new prosthesis.

Allograft bone struts can be used in the treatment of bone defects that have failed to heal (non-unions), especially when there is a need for additional mechanical support. The strut is placed over the non-union site to provide stability and facilitate bone healing.

In complex joint revision surgeries, allograft bone struts are used to provide structural support in situations where there is significant bone loss. The struts are typically used in conjunction with other reconstruction techniques to fill bony defects and enhance stability for the prosthesis.

Allograft Prosthetic Composites (APCs) are utilized in joint revision arthroplasty procedures to address complex cases where significant bone loss or structural defects are present. These composites combine a prosthetic component with allograft material to restore joint function and stability. They provide biological support for bone ingrowth and incorporation, ensuring long-term stability while reducing the need for excessive reliance on bone cement or metal augmentations.

Allograft-Prosthetic Composites (APCs) are used in orthopedic oncology for limb salvage operations following tumor resection. In such cases, a large bone tumor is surgically removed, often resulting in a significant loss of bone and soft tissue. To restore function and structure, an allograft can be used in combination with a prosthesis. The allograft can provide a biological scaffold for the patient’s tissues to grow and heal, while the prosthesis offers immediate mechanical support and stability.
