Der Mensch besitzt insgesamt verschiedene Knochen. Jeder Knochen besteht aus mineralischen, elastischen und bindegewebigen Komponenten. Frakturheilung Knochengewebe heilt ohne Narbe ab. Die Knochenbruch-Heilungsdauer ist je nach Skelettabschnitt verschieden. Ein Knochenbruch kann bei Kindern daher meist konservativ behandelt werden.

Faulkree J Bone Joint Surg Am ; 85 9: In klassifikatiin displaced tongue-type patterns, the posterior skin may be severely compromised due to pressure from the posterior calcaneal tuberosity, which is pulled proximally by the Achilles tendon. The Sanders CT classification is based on the location and number of fracture lines of the posterior articular surface as demonstrated by the coronal images at the widest part of the calcaneus.

J Bone Joint Surg Am ; 78 J Orthop Trauma; 15 4: Significant soft-tissue swelling is common and related to a combination of forces producing the injury and the persisting fracture displacement. AO Surgery Reference This fracture usually crosses the posterior articular surface. Classification Fracture classification assumes an understanding of major fracture displacements and fragments that are commonly observed.

Secondary intraarticular fracture lines green shown on a superior c and lateral view d. Primary intraarticular fracture line shown in a superior a and lateral b view of the calcaneus. Foot Ankle Int ; 17 Similarly, in displaced joint depression patterns, the fracture displacements may produce significant medial skin tension resulting in a skin klassifikatikn.

Fracture classification assumes an understanding of major fracture displacements and fragments that are commonly observed. In tongue-type patterns, a variable portion of the posterior articular surface remains in continuity with the tuberosity fragment.
