Abstract
Introduction Heterotopic ossification (HO) can be a potentially serious and devastating complication
following traumatic injury to the elbow. HO prophylaxis options include nonsteroidal
anti-inflammatory drugs (NSAIDs) and radiation therapy (RT) but neither has been proven
more effective. The purpose of this review is to compare effectiveness and outcomes
between NSAID and RT prophylaxis for HO about the elbow following a traumatic injury.
Materials and Methods We performed a systematic review of PubMed and Cochrane Library for cases of HO prophylaxis
following elbow trauma utilizing PRISMA guidelines to determine the most effective
form of prophylaxis. Outcomes of interest included recurrence of HO, range of motion
(ROM), and Mayo elbow performance index (MEPI). A total of 36 articles and 826 elbows
of which 203 received RT and 623 received NSAID were identified and included in the
final analysis.
Results Rates of HO formation or recurrence following elbow trauma were similar between radiation
and NSAID prophylaxis (15.6% vs. 22.2%, respectively p = 0.457). ROM was similar in flexion and extension arc (109.0 degrees in radiation
vs. 112.8 in NSAIDs, p = 0.459) and in pronation and supination arc (118.9 degrees radiation vs. 134.7 degrees
NSAIDs, p = 0.322). MEPI scores were 79.19 in the radiation group and 88.82 in the NSAIDs group
at the final follow-up.
Conclusion There is no statistical difference in HO development, recurrence, or final ROM between
NSAIDs and RT prophylaxis following trauma to the elbow. We recommend the choice of
modality based on patient characteristics, cost, and surgeon preference.
Level of Evidence Level III.
