TO EVALUATE THE ACCURACY OF PRE-OPERATIVE DIGITAL TEMPLATING IN FINDING THE PROBABALE FEMORAL HEAD SIZE TO THAT OF ACTUAL INTRAOPERATIVE SIZE IN BIPOLAR HEMIARTHROPLASTY OF HIP.

Abstract

Purpose: To evaluate the accuracy of pre-operative digital templating in nding the probable femoral head size to that of actual intra-operative size in bipolar hemiarthroplasty of hip. After obtaining ethical committee clearanc Methods: e, 33 patients were included in the study who met the Inclusion criteria. They were subjected to pre operative X rays using a 5 Rupee coin as a reference template. The actual Femoral head size calculated intra-operatively using the head ring template was then compared to that of the probable head size derived as per formula. The study period was for 1 year and it was a prospective study. Pearson correlation r value Results: is .755; p<0.05 which indicates there is positive correlation between B1 Actual size of the Femoral head in cm with Formula value. Pearson correlation r value is .961; p<0.05 which indicates there is highly positive correlation between B1 Actual size of the Femoral head in cm with B2 Radiographic size of Femoral head in cm. Conclusion: This method is a convenient and practical method of scaling magnication which can be applied in everyday X-ray procedures. The current results support the hypothesis that this method enables accurate templating with digital X-rays.
