Slipped Capital Femoral Epiphysis — Flashcards

Flashcard 1: The main objective of treatment of Perthes disease is to relieve force on the femoral head to reduce any further _____

Answer: deformation (or collapse)

Flashcard 2: In DDH, _____ and internal rotation movements of the hip are decreased.

Answer: abduction

Extra: Clinical signs of DDH in an infant/child: - **Limited abduction** (most reliable clinical sign after the neonatal period) - **Limited internal rotation** (the limb is typically held in a position of external rotation) - **Asymmetric skin folds** (groin, thigh, or gluteal) - **Galeazzi sign** (apparent shortening of the femur) - **Ortolani and Barlow tests** (positive in the neonatal period for hip instability) - **Trendelenburg sign** (positive in walking children due to abductor weakness)
