  • How the Body Works : Repair of Bone How the Body Works Repair of Bone The fracture of a bone is usually caused by direct violence or by a strong twisting strain. When a bone fractures the two fragments separate and in so doing tear the arteries in the Haversian systems that cross the fracture line. This damage results in the leakage of blood into the fracture, where it is trapped and soon clots. After a short time, the Haversian arteries go into spasm, causing the death of active bone cells not only at the fracture site, but also for some distance along the shaft. About two days after the break, the blood clot is invaded by capillaries and fibroblasts. The fibroblasts differentiate into bone-forming cells, or osteoblasts, and cells that form periosteal tissue on the outside of the bone. New tissue, called callus, surrounds the fracture and replaces the dead bone. The dead bone is absorbed and replaced by new bone, formed by the osteoblasts in the callus, which is remodeled by cells, called osteoclasts, to its original shape. This remodeling process is so effective that after a few months it is difficult to detect the fracture site.

  • Karnataka_flap_web.mov Patients underwent open mastoidectomy procedure, cavity obliteration and wide concho-meatoplasty procedure. Posteriorly based Perichondrial-periosteal flap (Karnataka Flap) and conchal carilage were used to obliterate the mastoid cavity. Various components of the three steps: open mastoidectomy, meatoplasty and cavity obliteration are done with post-aural approach and each step is inter-related and complements each other. The surgical technique presented here is easy to perform, less time consuming, easily reproducible, allows fast healing of the cavity, helps in improving the hearing and minimizes the postoperative cavity care.

  • B 025 sekundäre Knochenheilung - fracture healing Zunächst tritt aus der Bruchfläche Blut aus und es bildet sich ein Bluterguss (Hämatom). Dieses führt zu einer Aktivierung der Entzündungskaskade und Entzündungszellen setzen Zytokine wie Interleukin-1 und Interleukin-6 frei. Das Blut gerinnt, wird durch Granulationsgewebe ersetzt und es bildet sich zunächst eine bindegewebige Narbe. Diese Prozesse bilden zunächst eine elastische Verbindung der Bruchenden und schränken deren Beweglichkeit ein. Durch eingewanderte Knorpelbildner (Chondroblasten) kommt es zur Bildung von Faserknorpel, der allmählich durch aktivierte Osteoblasten verknöchert. Die so entstandene Manschette ist deutlich dicker als der übrige Knochen und wird als Kallus bezeichnet. English: Within a few hours after fracture, the extravascular blood cells, known as a "hematoma", form a blood clot. All of the cells within the blood clot degenerate and die. Within this same area, the fibroblasts survive and replicate. They form a loose aggregate of cells, interspersed with small blood vessels, known as granulation tissue. Days after fracture, the cells of the periosteum replicate and transform. The periosteal cells proximal to the fracture gap develop into chondroblasts and form hyaline cartilage. The periosteal cells distal to the fracture gap develop into osteoblasts and form woven bone. The fibroblasts within the granulation tissue also develop into chondroblasts and form hyaline cartilage. These two new tissues grow in size until they unite with their ...
