Abstract
Introduction: Total hip arthroplasty in the setting of hip infection is challenging because of high susceptibility of periprosthetic joint infection. Our aim is to assess outcome following use of prosthetic hip spacer in treatment of hip infection.
Patients and Methods: Prospective study was undertaken at Kasr El-Aini Hospital on 31 patients using prosthetic hip spacer in the intermediate stage in order to control hip infection. All patients were followed for a minimum of 3 months after 1st stage, then for a minimum of 1 year after 2nd stage. Mean age was 51.8 years. Male to female ratio is 67.7% to 32.3%.
Results: After 1st stage, mean HHS was 77.3, mean OHS was 33.2. Two cases suffered from persistence of infection. 2 cases suffered from dislocation. 1 case suffered from peripros-thetic cracks. 1 case suffered from acetabular cup migration upwards. The mean follow-up period after 1st stage procedure was 5.2 months. After 2nd stage, mean HHS was 87.4, mean OHS was 39.9.
Discussion: THA following hip infection is a challenging clinical problem. Infection clearance rate was 93.6%. Our series didn't show any mechanical or medical complications in comparison to those using custom made or static spacer respectively. Using articulating spacer provided much im-provement in functional outcome after both 1st & 2nd stage.
Conclusion: We conclude that prosthetic hip spacer is safe and effective mean of treating infected hips with good success rates.
