Abstract
Background
Level 1 studies for fracture management of upper extremity fractures remains rare. The influence of these studies on management trends has yet to be evaluated. The purpose of this study was to examine alterations in national trends managing mid-shaft clavicle and intra-articular distal humerus fractures (DHF) surrounding recent Level 1 publications.
Methods
We retrospectively reviewed a comprehensive Medicare (2005–2012) and Humana (2007–2014) patient population database within the PearlDiver supercomputer (Warsaw, IN, USA) for DHF and mid-shaft clavicle fractures, respectively. Non-operative management and open reduction internal fixation (ORIF) were reviewed for mid-shaft clavicle fractures. ORIF and total elbow arthroplasty (TEA) were reviewed for DHF. Total use and annual utilization rates were investigated using age limits defined in the original Level 1 studies.
Results
A total of 4,929 clavicle patients between 15 and 59 years, and 106,535 DHF patients greater than 65 years of age were coded. There was no significant change in annual volume of mid-shaft clavicle fractures and DHF coded (p=0.078 and p=0.614, respectively). Among clavicle patients there was a significant increase in ORIF utilization following the publication of the Level 1 study (p=0.002), and a strong, positive correlation was evident (p=0.007). No significant change in annual TEA (p=0.515) utilization for DHF was seen.
Conclusion
A significant increase in the utilization of ORIF for clavicular fractures was observed following the publication of supporting Level 1 evidence. This was not observed following similar evidence in managing DHF, as no increase in utilization of TEA was observed.
