The treatment of bone defects
Huge bone defects arise during extirpation of bone tumors, comminuted fractures near or including the joint (pilon tibial or similar fractures), but also from loosened components in joint replacement (Fig. 136 a). The huge cavities do not heal with a physiological bony scaffold if no osteoconductive filling of the cavities is providing a scaffold which can be colonized by osteoblasts.
The form‐giving element for a physiological scaffold of cancellous bone is the bead.
The micro‐chambered beads suction in blood and bone marrow, bleeding is stopped and adult stem cells start the bone healing from inside the ceramics. In large cavities, the combination of Ceraball®, comprising a diameter of 6 mm and 4 mm guarantees a perfect filling of the defect (Fig 136 b). Covering the defect with a sponge, the beads can be packaged via the syringe injection of NaCl. In fully developed osteoporosis, it is understood that a mixture of Ceraball® Syntricer® and Synthacer® represent the best bone void filling (Figs. 136 c and 136 d).
Detailed instructions can be found in the Manual Springer 2012.
