Salter (Rang) type 6 physeal injury

Abstract

Type 6 physeal injuries, described by Rang as a displacement of the perichondrial ring usually caused by a lawn-mower scalping mechanism or a closed trauma to the distal femoral physis avulsed by the lateral collateral ligament, are extremely rare. This type of injury was later included in Salter and Harris' classification of physeal injuries as type 6.

No large series of type 6 physeal injuries has been described in the literature. The aim of the study is to present a relatively large series of patients with this trauma and offer some new observations.

Although no larger series of type 6 physeal injuries has been described to date, it is clear that the mechanism of trauma has changed from earlier reports of open lawn-mower injuries to closed soccer and athletic sports fractures. Closed type 6 injuries are usually not or only minimally displaced and do not require surgery.

Open fractures were associated with soft tissue loss; they were caused by scraping of the ankle (knee, elbow) by a car or bicycle wheel on a road surface or the result of a gunshot injury with the projectile destroying the peripheral portion of the physis.
