The purpose of the study was to investigate whether closed intramedullary
(IM) nailing with percutaneous cement augmentation is better than
conventional closed nailing at relieving pain and suppressing tumours
in patients with metastases of the femur and humerus. A total of 43 patients (27 men, 16 women, mean age 63.7 years,

Patients and Methods
We have developed a hollow perforated cannulated screw. One or more of these was implanted percutaneously in 11 patients with an osteolytic metastasis in the femoral neck and multiple metastases elsewhere. They were supplemented by one or two additional standard 6.5 mm cannulated screws in nine patients. Polymethylmethacrylate bone cement was injected through the screw into the neck of the femur using small syringes, as in vertebroplasty. The mean amount of cement injected was 23.2 ml (17 to 30). Radiotherapy was started on the fourth post-operative day and chemotherapy, on average, was resumed a day later. Good structural stability and satisfactory relief from pain were achieved in all the patients. This technique may be useful in the palliation of metastases in the femoral neck.
