We report a prospective cohort study of the midterm results of
surgical dislocation of the hip (according to Ganz) to perform resection
of osteochondromas involving the femoral neck in patients with multiple
hereditary exostoses (MHE). Hip range of movement (ROM) was assessed pre- and post-operatively.
Patients’ judgment of post-operative reduction of pain, symptoms,
the Rand 36-item Health Survey (RAND-36) and complications were
analysed. Aims
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.
