Abstract

 Background:
This study addresses the null hypothesis that there is no expansion of heterotopic ossification (HO) in the
elbow beyond what can be seen early on.  

Methods:

The area of HO was measured on lateral radiographs of 38 consecutive patients that had operative treatment of HO between 2000 and 2013. Measurements from radiographs obtained between 3 to 7 weeks were compared to measurements from radiographs made 3 months or more after injury.

Results:

There was no significant difference between the average area of HO on the first (median 2.8 square centimeters, Q1: 1.5, Q3: 5.1) and later radiographs (median of 2.8 square centimeters, Q1: 1.4, Q3: 5.0) (P = 0.99).
Discussion: According to our results the area of HO does not expand beyond what can be seen early in the disease process.
