case_images: Pre-operative anteroposterior pelvis (A) and right hip lateral (B) views in a 27-year-old female with symptomatic anterior rotatory instability and early degenerative changes. Offset correction and labral re-fixation was performed along with a derotational osteotomy of 15  correction (C). For evidence of poor bony union (D) in the setting of chronic smoking, the patient underwent revision fixation 6 months after index surgery. Satisfactory osteotomy site healing was achieved (E) and, at 2 years of post-operative follow-up, she had a good clinical outcome with no instability observed and resolution of her symptoms.
