Quantitative assessment of the loss of functionality associated with the appearance of complications in osteosynthesis of proximal humerus fractures

Abstract

OBJECTIVE: To evaluate the relationship between incidence of complications and clinico-functional outcomes, after fractures of the proximal humerus treated with locking plates.MATERIAL AND METHODS: Our study reviewed 47 patients who underwent internal fixation with plate for a period of 5 years. We present the clinico-functional outcomes with Constant-Murley and Quick-Dash scores, and cinematic analysis. Statistical analysis of the relationship complication-functional results and new surgery-functional results.RESULTS: At the end of the follow-up period, a total of 47 patients were recollected and the mean age was 74,85 years. 11 patients (23,4%) had complications, of whom 6 patients (12,7%) needed a new surgery. The complication rate is associated with loss of 65,41º of flexion, 14,49º of extension, 36,71º of abduction, 8,84º of aduction, 5,47º of external rotation and 30,82º of internal rotation. Furthermore, we found statistically significant differences between the incidence of complications and Constant-Murley and Quick Dash scores.CONCLUSION: There is a high percentage of patients who developes complications after ORIF with and its functionality is significantly reduced. Our study accurately quantifies this loss and, in this way, it predicts the functional situation, according to the possible complicactions that may arise.
