Abstract:
Heterotopic ossification (HO), a common complication after elbow trauma, causes severe limb disability, Surgical resection is usually performed for post-traumatic elbow HO (PTEHO) to regain mobility. Though it was heavily reported, there has been no long-term (minimum 5-year) follow-up. Patients and Methods: 173 patients who underwent PTEHO resection were followed up for minimum 5 years in 4 hospitals between January/2015 and August/2016. Demographics, disease characteristics, preoperative and minimum 5-year assessments were collected. After controlling for potential variables when dividing long-term ROM into 〈 120° and ≥120°, risk factors for ROM recovery to modern functional arc were identified through multivariable regression analysis. Results: Clinically important improvements in ROM of 39°→124° were obtained at final follow-up, and 74.6% achieved modern functional arc (≥120°). Mayo Elbow Performance Index (MEPI) had clinically important increases of 69→93 points at final follow-up, and 96.5% reported excellent-to-good. Pain (Numerical Rating Scale, 1.9→0.6 points) and ulnar nerve symptoms were improved. Total complication rate was 15.6%, including new-onset ulnar nerve symptoms (5.8%), HO recurrence with clinical symptoms (6.9%), elbow instability (1.7%), and joint infection (1.2%). Previously reported high body mass index (BMI, p=0.002) and long disease duration (p=0.033) were equally identified as risk factors for not achieving modern functional arc, meanwhile tobacco use (p=0.024) and ankylosed HO (p 〈 0.001) were found to be new risk factors. Conclusion: Surgical resection yields satisfactory outcomes for PTEHO at long-term of minimum 5 years. High BMI, tobacco use, long disease duration, and ankylosed HO would negatively affect ROM recovery to modern functional arc (≥120°). Level of evidence: Level IV, therapeutic study.
