Experimental Induction of Physeal Injuries by Fracture, Drill, and Ablation Techniques: Analyses of Immunohistochemical Findings.

Background: Although physeal fractures and physeal bars can result in significant clinical consequences to growth and development of the injured physis, little orthopaedic research has focused upon this topic. Our objective was to extend a previously developed rat model to examine the immunohistochemical features following surgical application of techniques disrupting the physis.

Methods: Physes were surgically disrupted using fracture (control), epiphyseal scrape (ES), or epiphyseal drill (ED).

The Role of the Basement Plate in Physeal Bar Formation.

Background: Physeal fractures and resultant physeal bars can pose significant problems in skeletal development for the injured growing child. Although now well-recognized, only a small body of experimental literature covering this problem is available. The goal of this study was to help further develop an understanding of the different regions of the physis and the way in which each region responds to injury/fracture.
