Abstract

Slipped capital femoral epiphysis (SCFE) remains the most common adolescent hip disorder. Most cases present with stable slips, and in situ fixation is the most commonly adopted treatment worldwide. The introduction of the concept of femoroacetabular impingement and subsequent studies have revealed SCFE-related hip impingement to be a significant pre-arthritic condition, and the previously suggested remodeling of the proximal femur after in situ fixation has been called into question. Complex proximal femoral osteotomies and more recently intra-articular procedures via surgical hip dislocation have been employed. The literature is still lacking a strong evidence to undertake such aggressive procedures. Moreover, the application of a particular procedure regarding the nature of the slip, being stable or unstable, the degree of the slip, and the condition of the physis has not been extensively described in the literature. The purpose of this article is to outline the SCFE-related hip impingement, to review the best evidence for the current treatment options for both stable and unstable slips, and to develop an algorithm for decision making.
