A Cross Sectional Study of the Relationship between Fibonacci Ratio and Trigger Finge

Abstract

Introduction: Trigger finger is one of the most common causes of hand pain in adults. The pathophysiology is unclear but inflammation and age-related degeneration have been suggested. The equiangular spiral is one of the most engaging patterns which perfectly formed flawlessly executed by transitory movement of the digits in the adaptability of the human hand. This study was done to find out the relationship between the Fibonacci ratios of the finger with trigger fingers. Method: Forty-eight patients who had trigger finger and undergone A1 pulley released were being identified and collected. From the hand radiograph, the length of each metacarpal and proximal phalanx was measured manually. The ratio of the metacarpal bony length to the length of the respective proximal phalanx is the Fibonacci ratio of the digit. Results: There was a significant linear relationship found between trigger finger and Fibonacci ratio (p<0.001). Conclusion: Finger Fibonacci ratio significantly determines the smoothness patterns of its tendon movements.
