Patients\u2019 judgment of post-operative reduction of pain, symptoms, the Rand 36-item Health Survey (RAND-36) and complications were analysed. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> Symptomatic osteochondromas of the femoral neck were removed in 20 hips (17 patients) between 2007 and 2012. There were nine men and eight women with a mean age at the time of surgery of 29 years (11 to 47). Mean follow-up was 46 months (26 to 73). At latest follow-up, mean ROM was significantly increased in all directions. Post-operatively the pain associated with the lesion was either significantly decreased or non-existent. There was a significant improvement in seven RAND-36 sub-domains. Encountered complications in four patients were pseudoarthrosis of the trochanteric osteotomy, traumatic separation of the trochanteric osteotomy, a pertrochanteric femoral fracture and avasvular necrosis. Histological analysis revealed osteochondromas in all hips. <\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p> This study confirms the Ganz trochanteric flip osteotomy provided a reliable approach to osteochondromas of the femoral neck that are otherwise difficult to access for surgical resection. The procedure offered significant improvement in the quality of life, although one should be aware of the serious complications can arise despite the relatively safe procedure. Take home message: When daily function and activities are affected, resection of osteochondromas of the proximal femur according to Ganz is indicated to significantly improve quality of life.
