Multivariable analysis: independent predictors of HO restricting motion

Variable p value Odds ratio (95% CI)
Coronoid fracture NS
Olecranon fracture NS
Complete ulnohumeral dislocation 0.048 2.38 (1.01–5.64)
Time from injury to surgery 0.01 1.12 (1.03–1.22)
Number of surgeries within 4 weeks of injury 0.004 2.88 (1.39–5.96)

HO = heterotopic ossification; NS = not significant.
