We present the case of an 82-year-old female, who experienced a ground-level fall on the trochanter of the right femur. X-rays showed a proximal femoral fracture (PFF) with an unclear and unusual fracture pattern. Three-dimensional CT images were obtained and showed a displaced femoral neck fracture and ipsilateral fracture of the greater trochanter. Our patient underwent unipolar hemiarthroplasty and fixation of the greater trochanter with a hook plate and cable grip. At 11 months, functional outcomes, patient satisfaction and quality of life were excellent. Primary osteoporosis was diagnosed and treatment with bisphosphonates was initiated.Two-level PFFs are rare and complex. Due to ageing and a subsequent increase in osteoporosis, numbers of PFFs with complex fracture patterns might increase in the future. Adequate treatment and early prevention of osteoporosis are key to reduce this risk and lower the overall burden. Surgical treatment should be patient-tailored and focus on minimising the risk of complications and reinterventions.
