Incidence and Associated Factors of 2-Legged Nitinol Staple Breakage in Foot and Ankle Surgery

Listen to this summary

The authors aimed to investigate the incidence and factors associated with breakage of 2-legged nitinol staples (NSs) used in foot and ankle surgery. They found an overall breakage rate of 4.0%, with higher rates in specific anatomical sites and certain fixation strategies, suggesting that factors such as anatomical location, staple geometry, and fixation method may influence the risk of staple breakage.
