“…In the present analysis, it stands out that alloplastic materials (PEEK, PMMA) or metals (titanium) are not subjected to fracturing or loosening, while porous materials (PHA) are affected by this complication. This is due to the intrinsic chemico-physical features of HA [19]. In pediatric patients, brain pulsation during a child's growth can affect the device stabilization and cause mobilization of the CP material.…”

Introduction. Cranial reconstruction (CR) is a neurosurgical procedure performed to restore the cranial vault after a decompressive craniectomy. There are contrasting reports from the literature about the complications related to the use of heterologous materials for CR in the pediatric population. In this study, the authors we try to better define such rate of adverse events for autologous and heterologous materials Material and method. A systematic review of articles published up to December 2021 was performed. Studies were included if they reported the specific use of cranioplasty materials following craniectomy in patients younger than 18 years of age, and had a minimum follow-up of at least 1 year. Results. A total of 20 studies have been selected. A total of 544 cases were included, of which 422 cases (77.6 %) with heterologous materials and 122 cases (22.4%) with autologous bone. The mean average age was 9.5 years. PEEK and PMMA reported 29% and 33.3%, respectively of complications but only 3% and 5.6%, of surgical revision. PHA reported a rate of 11.9%. Titanium reported 9.2% complications and 4.1% of surgical revisions. Porous polyethylene had a complication rate of 36.4% and a revision rate of 0%. Conclusion. There is still no perfect material for CR. it seems that heterologous materials are superior to autologous bone for CR is children and we may consider, whenever economical conditions will allow it, to use alloplastic material as first-line in small children

The surgical repair of a bone deficiency in the skull caused by a prior procedure or accident is known as cranioplasty. There are various types of cranioplasties, but the majority entail raising the scalp and reshaping the skull using either the original piece of bone from the skull or a specially molded graft created from Titanium (plate or mesh), artificial bone in place of, a stable biomaterial (prefabricated customized implant to match the exact contour and shape of the skull). Cranioplasty, one of the oldest surgical treatments for cranial abnormalities, has undergone several changes throughout the years to discover the best material to improve patient outcomes. Various materials have been utilized in cranioplasty throughout history. As biomedical technology progresses, surgeons will have access to new materials. There is still no agreement on the optimum material, and research into biologic and nonbiologic alternatives is ongoing in the hopes of finding the finest reconstruction material. The materials and techniques used in cranioplasty are covered in this article.

“…In addition structure-based osteoconductivity, they also serve as a source of calcium ions for ossification through surface dissolution ( Tang et al, 2018 ). They have been studied extensively and put into clinical use in bone substitution, reconstruction, and drug delivery ( Ragaey and Van Sickels, 2017 ; Maenhoudt et al, 2018 ; Zhao et al, 2020 ). The porous structure of the materials also provides good absorption of liquid state platelet derivatives.…”

Articular cartilage has limited self-regeneration ability for lacking of blood vessels, nerves, and lymph that makes it a great challenge to repair defects of the tissue and restore motor functions of the injured or aging population. Platelet derivatives, such as platelet-rich plasma, have been proved effective, safe, and economical in musculoskeletal diseases for their autologous origin and rich in growth factors. The combination of platelet derivatives with biomaterials provides both mechanical support and localized sustained release of bioactive molecules in cartilage tissue engineering and low-cost efficient approaches of potential treatment. In this review, we first provide an overview of platelet derivatives and their application in clinical and experimental therapies, and then we further discuss the techniques of the addition of platelet derivatives and their influences on scaffold properties. Advances in cartilage tissue engineering with platelet derivatives as signal factors and structural components are also introduced before prospects and concerns in this research field. In short, platelet derivatives have broad application prospects as an economical and effective enhancement for tissue engineering–based articular cartilage repair.
