Clinical And Radiological Evaluation of Fully Hydroxyapatite Coated Uncemented Stems in Hip Arthroplasty
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 2
Abstract
To assess the functional and radiological outcome of fully hydroxyapatite coated stems in hip arthroplasty. Prospective and retrospective study. Follow up 6wks,3mths,6mths,1year & then yearly. Minimum follow up of 6 months. Total No. of cases in the study : 31 patients (32 hips). All cases were done using STANDERD CORAIL stem. Mean age – 60.31years (19years to 94years). In our study all hips were operated through posterior approach. Clinical evaluation with Harris hip score (Modified) and radiological evaluation with plain x-ray pelvis with both hips and proximal femur - AP view and x-ray of the operated hip - AP view and Lateral view was done for all patients at regular intervals. The 32 hips were evaluated both clinically and radiologically. There were 3 cases with vertical subsidence. Mean Pre-operative HHS : 24.3333 ( 12 cases). Mean Post-operative HHS : 91.6563. There were 2 cases of limb lengthening. There was no significant changes in clinical outcomes with minimal varus/valgus stems in our study. HA coated stems give excellent results in short term follow-up. Following hip arthroplasty with HA coated stem there is no clinically significant anterior thigh pain. Long-term follow-up is required to assess the incidence of Heterotopic Ossification with this stem. Intra-operative fissures and post-operative fractures are not related to them stem design, but can be avoided with careful and less aggressive reaming of the femoral canal.
