The purpose of the study was to assess the safety of Intra-articular steroid hip injections (IASHI), prior to ipsilateral total hip arthroplasty (THA). We investigated whether there was an excess of infection in such a group 7–10 years after total hip arthroplasty. A database of 49 patients who had undergone IASHI followed by ipsilateral THA was reviewed.Aim
Method
Recurrent dislocation after hip arthroplasty is a difficult problem. The purpose of the present study was to evaluate the results with the use of a constrained cup for treatment for instability after hip arthroplasty. A prospective database of 30 patients who underwent revision hip surgery for dislocation of hip arthroplasty was kept with the surgeries taking place between Nov 2005 to Feb 2010.Introduction
Materials/Method
Cementoplasty, like vertebroplasty, is a technique whereby Polymetylmethacrylate is placed into a bone lesion either percutaneouly or by surgery under image intensifier guidance. Although there have been few studies with regard to cementoplasty percutaneously, there is no series in the literature to support the open surgical technique as a palliative procedure. In our series we describe four patients (1male and 3 females, age range 63-83) with metastatic bone cancer who have benefited from an open surgical procedure. The four patients presented to our hospital between January 2004 and December 2006. They all had gradually worsening hip pain at the time of presentation and pelvic radiographs revealed osteolytic lesions in the acetabulum. A 5 centimetre longitudinal incision proximal to the greater trochanter was made and the malignant lesion identified using the image intensifier. The malignant tissue was curetted and sent for microscopy, culture, sensitivity and histopathology and the remaining void filled with bone cement (via a gun or by hand) under x-ray control. Radiographs were taken in all patients post-operatively and were referred for adjuvant radiotherapy. All patients had immediate relief of pain and were able to mobilise within 48 hours. Two patients died within 6 weeks post-operatively due to complications from their primary malignancy (lung). One patient died at three months due to unknown primary. One patient remained pain free and fully ambulatory at one and a half years post surgery (breast primary). This procedure can be recommended for patients with metastatic bone disease as it provides adequate pain control and improves the quality of life in this group of patients. These patients need a multi-disciplinary approach to their care, but as orthopaedic surgeons, we can make a significant impact to such patients and their families.
