The use of demineralized bone transplants is found to increase the effectiveness of allogenic transplantations of bone tissue due to its ability to induce active osteogenesis even when implanted intramuscularly. The method of preparing the bone transplants by demineralization in solutions of hydrochloric acid should be widely used in traumatology and orthopedy.

The aim of the circular economy is to treat waste as a valuable raw material, reintegrating it into the industrial economy and extending the lifecycle of subsequent products. Efforts to reduce the production of hard-to-recycle waste are becoming increasingly important to manufacturers, not only of consumer goods but also of specialized items that are difficult to manufacture, such as medical supplies, which have now become a priority for the European Union. The purpose of the study is to manufacture a novel human-purified type I collagen membrane from bone remnants typically discarded during the processing of cortico-cancellous bones in tissue banks and to evaluate its mechanical properties and effectiveness in regenerating bone-critical mandibular defects in rabbits.

Background: Demineralized bone matrix (DBM) is a commonly utilized allogenic bone graft substitute to promote osseous union. However, little is known regarding outcomes following DBM utilization in foot and ankle surgical procedures.
Aim: To evaluate the clinical and radiographic outcomes following DBM as a biological adjunct in foot and ankle surgical procedures.

In an effort to mitigate or reverse the pathological progression of early-stage osteonecrosis of the femoral head (ONFH), this study employed a promising strategy that involves the sustained delivery of osteogenic factors to augment core decompression, facilitated by the use of composite hydrogels. Specifically, a hydrogel was synthesized by blending chitosan, Pluronic F-127, and tripolyphosphate, utilizing both ionic bonding and copolymer micelle cross-linking techniques. This hydrogel demonstrated exceptional biocompatibility, temperature responsiveness, pH-dependent biodegradation, and controlled release properties.

Orthopedic, maxillofacial, and complex dentoalveolar bone grafting procedures that require donor-site bone harvesting can be associated with post-surgical complications. There has been widespread adoption of exogenously sourced particulate bone graft materials (BGM) for bone regenerative procedures; however, the particulate nature of these materials may lead to compromised healing outcomes, mainly attributed to structural collapse of the BGM, prolonged tissue healing. In this study, a fully synthetic thermoresponsive hydrogel-based universal carrier matrix (TX) that forms flowable and shapable putties with different BGMs while spatially preserving the particles in a 3D scaffold at the implantation site is introduced.

The aim of this article is to determine the safety and efficacy of core decompression (CD) combined with injection of autologous bone marrow concentrate (BMC), demineralized bone matrix (DBM), and platelet-rich fibrin (PRF) for treating femoral head osteonecrosis. Seventy-seven patients (53 males and 24 females) for a total of 87 hips were treated for hip osteonecrosis with CD combined with injection of autologous BMC, DBM, and PRF at Rizzoli Orthopedic Institute from September 2008 to December 2019. Patients were assessed at baseline, at 45 days, and at 3, 6, 12, 24, and 36 months postoperatively.
