Development of Bilateral Cam Deformity After Dunn Procedure and Contralateral Prophylactic Fixation: A Periosteal Reaction?

Case: We present the case of a fourteen-year-old male athlete with a slipped capital femoral epiphysis who was managed with a unilateral Dunn procedure and contralateral prophylactic screw fixation. Even though the cartilaginous epiphyseal growth plate was removed on one side, cam deformities subsequently developed on both sides in the postoperative period. Conclusion: This case suggests that structures other than the growth plate are also capable of inducing cam deformity of the hip.
