The Synthetic Scaffold: Developments and Applications of Calcium Phosphate Bone Cements
When an orthopedic surgeon faces a massive bony defect—whether from trauma, tumor resection, or the settling of a depressed tibial plateau fracture—autograft bone (taken from the patient’s own iliac crest) is the gold standard, but it causes significant donor-site morbidity. The holy grail of orthopedics is a synthetic material that provides immediate structural support and eventually remodels into living bone. Developments and Applications of Calcium Phosphate Bone Cements is a fiercely specialized, highly technical manual detailing the most advanced synthetic bone substitutes in modern surgery. This volume provides the exact blueprints required to utilize these complex biomaterials effectively.
Mastering Biomaterial Science
The core philosophy of this text is applied biochemistry. The authors aggressively detail the chemistry and crystallography of calcium phosphate (CaP) cements, specifically how they mimic the mineral phase of natural human bone (hydroxyapatite). It dictates exactly how these cements set in an aqueous, in vivo environment (an isothermic reaction, unlike the highly exothermic setting of PMMA bone cement, meaning CaP does *not* cause thermal necrosis of surrounding tissue).
Navigating Surgical Application and Osteoconduction
The book provides a masterclass in synthetic grafting. It dictates the exact clinical pathways for utilizing CaP cements in metaphyseal defects (e.g., distal radius fractures, calcaneal fractures), providing immediate compressive strength. It exhaustively details the biological process of *osteoconduction*—how osteoclasts resorb the cement while osteoblasts simultaneously lay down new woven bone, eventually replacing the synthetic scaffold entirely.
Frequently Asked Questions (FAQs)
Can I use this cement to fix a diaphyseal femur fracture?
No. The book clearly details the biomechanical limitations of CaP cements: they have excellent compressive strength but very poor shear and tensile strength, meaning they cannot be used in load-bearing diaphyseal defects without rigid internal fixation (like a plate).
Who is the primary audience?
It is a mandatory reference for Orthopedic Trauma Surgeons, Maxillofacial Surgeons, Spine Surgeons, and Orthopedic Researchers/Biomaterial Engineers.
