Slipped capital femoral epiphysis (SCFE) is a common adolescent hip disorder, and treatment aims to prevent slip progression, restore hip function, and avoid complications such as avascular necrosis (AVN) and early osteoarthritis. The modified Dunn procedure using Ganz surgical hip dislocation allows anatomical realignment while preserving femoral head vascularity. An 11-year-old boy presented with progressive left hip pain and limp for four months. Imaging confirmed moderate SCFE, and he underwent a modified Dunn procedure with safe surgical dislocation. Anatomical reduction was achieved, and at one-year follow-up, he showed excellent clinical and radiographic outcomes without AVN or recurrent slip, with significant functional improvement. While in situ fixation is traditional, it may leave residual deformity and predispose to femoroacetabular impingement and early osteoarthritis. The modified Dunn technique enables direct visualisation, deformity correction, and preservation of blood supply. This case highlights that, with appropriate expertise, the modified Dunn procedure is a safe and effective option for moderate SCFE with favourable outcomes.
