We obtained MSTS and SF-36 scores for the ten patients who were alive at nal follow-up. Their mean MSTS score was 49% (13 to 87) and was signi cantly worse for patients in whom complications occurred (Mann–Whitney, p = 0.02). The mean physical and mental component scale scores of the SF-36 were 56 (39 to 68) and 47 (23 to 62), respectively. One patient used codeine as an analgesic on a daily basis, nine years after the index procedure.
Discussion
Reconstructing a functional, pain-free limb after periacetabular resection is demanding. Although experiences with the pedestal cup in both revision hip arthroplasty and orthopaedic oncology have previously been described27-29, this is the rst study which reports its use in a consecutive series of patients with a pelvic malignancy.
The complication rate was high with 15 patients (79%) a ected. Seven had mechanical complications, none of which required removal of the prosthesis. Failure of the reconstruction occurred in eight patients, six owing to infection and two to recurrent disease. With failure for non-oncological reasons as the end-point,
