Related to perichondrial: Perichondrial hematoma


The fibrous connective tissue covering cartilage, except at joints.



connective tissue that invests cartilage. Perichondrial cells become differentiated into cartilaginous cells at the same time as the dense homogeneous basic matter of the cartilage forms. In young organisms the perichondrium is converted to periosteum in the process of the development of bone from cartilage.

The purpose of this study was to determine the torsional strength of the capital femoral epiphysis and the role of the perichondrial ring in resisting torsion and to establish the porcine model as an analogue to human slipped capital femoral epiphysis (SCFE) in order to aid in the development of SCFE treatment.
After flap elevation, the anterior and posterior edges of the helical rim, which were pedicled on the medial perichondrial flap, were advanced and reapproximated; redundant soft tissue on the medial side of the auricle was excised and closed.
By using a cartilage plate with a strip of perichondrium still attached, the perichondrial part of the graft was pulled through this tunnel by using a small hook.
