Abstract
Aims: The main purpose of this study was to evaluate hemiplevis replacements in patients with periacetabular tumours in terms of the functional results and implant survivorship of the prosthesis. The second aim was to evaluate the complications and how they might be prevented in the future.
Methods: Case notes, hospital databases and radiographs were reviewed in 51 patients treated in a 16 year period with a custom made hemipelvis replacement (Stanmore Implants Worldwide). There were 13 deaths and 4 were lost to follow up. Of the remaining 34 patients there were 18 males and 16 females with a mean age of 48.6 (range 14 – 71).
Results: At a mean follow-up of 78 months (range 7 – 204), 70% of patients were still alive and the most common diagnosis was chondrosarcoma (17 cases). There were 2 cases of prosthesis failure and 22 of the 34 patients had one or more complications (12 cases of infection (8 deep and 4 superficial), 4 nerve palsies, 2 dislocations and 7 others). 13 patients had to have a second operation. The mean MSTS score was 63.8% and the TESS score was 59.8%
Conclusion: Infection was the most common complication and was the most significant reason for reoperation. This method of reconstruction is associated with a high morbidity rate and should be performed only at specialist centres, but the functional and oncological outcomes are satisfactory.
