Eight patients with stable osteoporotic proximal humerus fractures were randomized to undergo an intensive early mobilization program (n=40) or early conventional mobilization program (n=40). Primary outcomes of interest included function evaluated using the constant shoulder score and the subjective shoulder value (SSV) which were both measured at 3, 6, and 12 months follow-up. Additional outcomes evaluated included the loss of reduction and incidence of non-union. Results revealed that none of the primary outcomes were statistically significantly different between the 2 groups at any of the timepoints (p>0.05 for all). The early conventional mobilization group demonstrated statistically greater incidence of loss of reduction at 3 months follow-up. One case of non-union was observed in the early intensive mobilization group.
