Cranial Bone Repair and Regeneration After Trauma: Forensic and Clinical Medico-Legal Consequences

Cranial bone defects caused by trauma present significant clinical challenges but also difficulties in their forensic analysis. The complexity of cranial anatomy, limited vascularization, and proximity to neural structures complicate natural bone regeneration, often requiring surgical intervention and the use of complex materials and techniques. This review aims to identify relevant data for forensic analysis regarding bone regeneration after trauma, with an emphasis on the materials used and their interpretation in medico-legal contexts. It moves beyond a simple clinical perspective, providing a detailed medico-legal analysis of cranial bone repair and regeneration after trauma. This review aims to give a comprehensive analysis of the forensic and medico-legal consequences associated with cranial reconstruction using autogenic, allogenic, xenogenic, and synthetic materials. It gives a pioneering focus regarding an understudied but critical aspect of forensic and legal medicine, both to postmortem and to clinical elements. By detailing the unique radiographic signatures and physical characteristics of various reconstruction materials, we provide the specialists with a go-to material for the interpretation of these materials in forensic contexts. Furthermore, we will provide a detailed analysis of medico-legal risks, mainly those associated with malpractice claims, focusing our attention on the process of informed consent but also the management and interpretation of surgery-related complications.
