Survival after pathological fractures of the proximal femur.

Abstract

We report on the survival of 145 patients presenting to a single centre with a pathological metastatic fracture of the proximal femur. The single surviving patient had a follow-up of 17.7 years. Mean survival for the 144 patients who died was 332 days (range 2 to 3053 days), being longest for those with myeloma (662 days), lymphoma (> 633 days) and breast tumours (477 days) and lowest for lung tumours (110 days). The most common sites for the primary tumour were breast (36%), prostate (23%) and lung (17%). 47% of fractures were intracapsular, 28% trochanteric and 25% subtrochanteric. 99% of the fractures were treated surgically with a mean hospital stay of 19 days. The commonest fracture healing complication was further fracture of the femur around or immediately below the implant which occurred after 9/144 (6.2%) of operations. The difference in survival of patients related to the primary tumour site is of relevance in planning surgical treatment and discussing prognosis with patients.
