Early functional mobilization for non-operative treatment of simple elbow dislocations: a systematic review.

Purpose:This systematic review aims to elucidate a non-operative rehabilitation program that optimizes recovery based on published approaches and outcomes. Methods:Searches of four databases from inception to 1 January 2020 were performed to identify clinical studies addressing the non-operative management of simple elbow dislocations. Results:Of 2435 studies that were eligible for title screen, 15 studies satisfied inclusion criteria. Three randomized control studies demonstrated that early mobilization expedited the return of range of motion, function and return to work or activities, however, resulted in increased pain within the six-week rehabilitation period compared to Plaster of Paris casting for 21 days. Patients returned to work sooner after early mobilization (10 vs. 18 days; p = 0.02) compared to Plaster of Paris casting. In all studies, early mobilization resulted in similar re-dislocation rates of 1.3% (3/237) versus 2.2% (12/549) in those with Plaster of Paris casting as well as lower incidence of heterotopic ossification (36% vs. 54%). No significant differences between rehabilitation protocols were determined; however, the large majority of recent papers utilized rehabilitation protocols. Conclusion:Early mobilization of simple elbow dislocations results in early return of Range-of-Motion, function and return to work with no increase in complication rates; however, increased pain during the rehabilitation period.
