Prognostic Factors of Refractures among Post-Surgical Hip Fracture Patients in Chiang Rai Provincial Hospital, Chiang Rai Province

Objective: To investigate which of the prognostic factors affects the post-surgical first hip fracture patients and continues to affect the development of the refractures later. Materials and Methods: The present study was the retrospective case-control. The data were collected from 232 of the first hip fracture patients aged 50 years or more that included 75 males and 157 females. The comparison was observation of the patients from 58 refracture patients (group 1) to 174 first hip fracture patients (group 2). Most of them were admitted and evaluated at Chiang Rai Prachanukroh Hospital between October 1, 2013 and September 30, 2020. Results: The findings of the present study indicated that the prior fracture history patients (adjusted OR 19.836; 95% CI 1.674 to 235.015, p=0.018) with lower Singh index grades 3 or less (adjusted OR 8.082; 95% CI 2.535 to 25.466, p≤0.001) and eye disease (adjusted OR 11.361; 95% CI 0.971 to 11.708, p=0.055) were the prognostic factors of refractures. Conclusion: In the prior fracture history, a lower Singh index (grade 3 or lower) and eye disease were the prognostic factors of refractures in the post-surgical hip fracture patients. Early detection of these factors can help to identify the high risk of the refracture group and improve the efficiency and targeting the prevention of refractures.
