[Hip arthroplasty in osteopetrosis: technical problems and operative solutions. Case report]

We present a patient with marble bone disease, who went through hip arthroplasty due to femoral neck fracture. We focused on large technical difficulties during the operation, resulting from sclerotisation and total atresia of femoral bone marrow cavity. We discussed some operative solutions which facilitate prosthesis implantation in patients with osteopetrosis.
