Background: Treating patients with osteopetrosis is very challenging even in very skilled surgeons with many experiences. We present an account of 5 patients treated for hip fracture related problems occurring throughout their life due to this disease. Difficulties encountered during their treatment prompted us to present some general management principles. Methods: From January 2003 to December 2016, 5 patients with osteopetrosis (9 hips; 3 men, 2 women), who underwent operative or conservative treatment were retrospectively reviewed. We evaluated their clinical features and rate of union, malunion and post-operative infection. Results: Four of 5 patients (80%) suffered bilateral fracture, and 8 of 9 fractures (89%) are transverse and occurred at subtrochanteric area resulted from minor trauma. Among 9 hips, surgery was performed in seven hips. Nonunion were found in 3 hips (33%), malunion in 1 hip (11%) and oteomyelitis was developed in 2 hips (22%) at a median of 8.1 years. Conclusions: Clinical features of hip fracture in osteopetrosis are very similar to atypical subtrochanteric femoral fractures. Patients should be informed of the possibilities of several anticipated complications including the risk of nonunion and infection after surgery.
