Abstract
Heterotopic Ossification (HO) is a known complication that can arise after total elbow arthroplasty (TEA). In most cases it is asymptomatic, however, in some patients it can limit range of motion and lead to poor outcomes. The objective of this review was to assess and report incidence, risk factors, prophylaxis, and management of HO after TEA.
A systematic search was conducted using MEDLINE, EMBASE, and PubMed to retrieve all relevant studies evaluating occurrence of HO after TEA. The search was performed in duplicate and a quality assessment was performed of all included studies.
A total of 1907 studies were retrieved of which 45 studies were included involving 2256 TEA patients. HO was radiographically present in 10% of patients and was symptomatic in 3%. Less than 1% of patients went on to surgical excision of HO, with outcomes following surgery reported as good or excellent as assessed by range of motion and Mayo Elbow Performance Scores (MEPS). TEA due to ankylosis, primary osteoarthritis, and posttraumatic arthritis are more likely to develop symptomatic HO.
HO is an uncommon complication following TEA with the majority of patients developing HO being asymptomatic and requiring no surgical management. Routine HO prophylaxis for TEA is not supported by the literature. The effectiveness of prophylaxis in high risk patients is uncertain and future studies are required to clarify its usefulness. The strength of these conclusions are limited by inconsistent reporting in the available literature.
