Bone Substitutes: From Basic to Current Update: Jong Seong Han, Hyung Keun Song; J Korean Fract Soc 2020;33(4):238-244. Published online October 31, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.4.238

Bone substitutes are being used increasingly in bony surgery as more than two million bone grafts are performed worldwide per year. Autobone grafts represent the gold standard for bone grafting, but morbidity and limited availability are the main problems. Allobone grafts are osteoconductive, but there are still concerns regarding the infection risks, costs, and donor availability issues. As an alternative, widely used ceramic-based synthetic bone substitutes are based alternatively on calcium (hydroxyapatite, tricalcium phosphate, calcium sulfate, calcium phosphate). Ceramic-based bone substitutes are osteoconductive, but they are weaker than cortical bone and are not osteoinductive. Bone morphogenic protein, demineralized bone matrix, and platelet-rich plasma are used to obtain an osteoinductive function. Recently, cell-based and gen-based bone substitutes were developed and studied. This paper reviews the basic information and the latest concepts on bone grafts and bone substitutes.

Bone Substitutes and the Advancement for Enhancing Bone Healing: Dong Hyun Lee, Ji Wan Kim; J Korean Fract Soc 2017;30(2):102-109. Published online April 30, 2017; DOI: https://doi.org/10.12671/jkfs.2017.30.2.102

Abstract PDF

With an aging population and the development of surgical techniques, there is a growing demand for bone reconstruction in areas of trauma, arthroplasty, and spinal fusion Although autogenous bone grafting may be the best method for stimulating bone repair and regeneration, there are still problems and complications, including morbidity related to bone harvesting and limitation of harvest amount. Allogeneic bone grafts have a limited supply and risk of transmission of infectious diseases. Over the past several decades, the use of bone substitutes, such as calcium phosphate, has increased; however, they have limited indications. Biomedical research has suggested a possibility of stimulating the self-healing mechanism by locally transmitting the external growth factors or stimulating local production through a gene transfer. In this review, we evaluate recent advances, including bone graft, bone substitutes, and tissue engineering.

The Efficiency of Additional Fixation of the Alternative Bone Substitute in Unstable Intertrochanteric Fractures of Femur Treated with Gamma Nail: Jong Oh Kim, Young One Ko, Mi Hyun Song; J Korean Fract Soc 2011;24(1):1-6. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.1

Abstract PDF: PURPOSE
To evaluate the efficiency of additional fixation of the alternative bone substitute in unstable intertrochanteric fractures treated with gamma nail and alternative bone substitute and only with gamma nail.
MATERIALS AND METHODS
Radiologic comparison was done between forty-four patients of unstable intertrochanteric fracture (AO type A2.2, A2.3) during six months. The patients were divided into two groups, a group treated with gamma nail and alternative bone substitute (22 patients, group 1) and another group treated only with gamma nail (22 patients, group 2). Postoperative reduction status, Cleveland index, Tip-apex distance and complications during the follow-up period was compared. Lag screw slippage and femoral neck-shaft angle change were measured between two groups.
RESULTS
No significant difference of reduction status, Cleveland index and Tip-apex distance was found. In group II, there was a 1 more case of cutting-out of the lag screw, but also there was a significant difference. Lesser change in lag screw slippage and neck-shaft angle change was investigated.
CONCLUSION
As there are lesser lag screw slippage and neck-shaft angle change, alternative bone substitutes applied in unstable intertrochanteric fractures seems to be useful in maintaining reduction and preventing failure of internal fixation when proper reduction and screw insertion is performed.
