Abstract

Background and Purpose: The aim of this paper is to present an alternative method of cranioplasty with the use of an autologous cranial bone flap stored between primary and restorative surgery in the subcutaneous pocket in the lateral hypogastric region., Material and Methods: Between January 1999 and April 2002, in the Department of Neurosurgery of Medical University of Łódź we performed 36 procedures of the bone flap implantation into the abdominal subcutaneous fat tissue. These procedures followed craniectomy, mainly in cases of acute subdural hematomas and ruptured intracranial aneurysms., Results: After storage, the bone flap was reimplanted in 28 patients. The mean time between operations was 14 days (range 8-53 days). In the cranioplasty group we had only one infection of the bone flap. Among patients excluded from the bone flap restoration we observed one inflammatory complication in the abdominal wall and one subcutaneous hematoma requiring evacuation., Conclusions: In our opinion, the presented method of the cranial defect's supplementation may be competitive to procedures utilizing synthetic prostheses in the population of patients for whom reimplantation of the bone flap will be expected in 2-3 months after the primary operation. Advantages of the procedure are: the autologous bone graft, the excellent cosmetic effect, low costs of the procedure and low rate of inflammatory complications.

Abstract

A recent study conducted by researchers at Wroclaw University of Science & Technology in Poland examined the physical, chemical, and biological properties of polymer-ceramic composites for bone tissue engineering. The composites were made using a combination of twin-screw extrusion and injection molding techniques. The materials were tested for various properties, including morphology, chemical composition, processing properties, thermal properties, strength, and surface properties. The results showed that the composites had good strength parameters, precise geometric shape, and slightly improved surface properties. However, the study also found that the composites provided favorable conditions for bacterial development, suggesting the need for further investigation into antimicrobial inclusion. Overall, the findings provide valuable information for the design and manufacturing of biocomposites for bone tissue engineering applications. [Extracted from the article]
