ABSTRACT
Increasing numbers of patients with hip replacements are presenting for pelvic radiotherapy, which is usually planned using CT images. Image artefacts caused by the presence of metallic implants tend not to be severe for single hip replacements and allow for adequate definition of target volumes. When bilateral hip replacements are present, the image artefacts can render CT images useless for target definition, particularly for tumours of the prostate and bladder. MR images are not susceptible to such severe artefacts. This note describes a small series of patients with bilateral hip replacements on whom CT-MR image registration has been used to successfully define adequate target volumes.

    The author discusses two studies that examine large national datasets from Finland and Great Britain to estimate risk of cancer in patients with metal-on-metal hip implants. These implants have become very popular in recent times owing to no increased risk in the short term. Doctors must explain...

    Periprosthetic osteolysis is the most common complication after total hip arthroplasty and is seen with increasing frequency due to the growing number of arthroplasties and lifetime of the implants (1). Most of the time the bone loss is due to wear-mediated inflammation that ultimately can lead...

    We describe a patient who developed a mass extending into the pelvis, five years after a metal-on-polyethylene total hip arthroplasty (THA). The histological pattern of perivascular lymphocytic infiltrate and fibrinoid necrosis was more in keeping with a metal-on-metal bearing failure. The...

    Clear cell chondrosarcoma is a rare tumor that can be easily confused with benign tumors. The aim of this report is to present a case that is rare, initially diagnosed as aneurysmal bone cyst and then chondroblastoma, and has an interesting extension pattern. A 41-year-old male patient was...

    Background: Reconstruction of bone after the resection of a pelvic tumor is challenging. The purpose of the present study was to evaluate the use of the ipsilateral femur as the graft material for reconstruction. Methods: We performed a retrospective review of thirteen patients with a malignant...
