Chebli CM, et al. - In this study, investigators examined 75 participants to quantify whether aortograft helped with higher humeral migration in a longer time and improved functional outcome measured as motion range. They recorded the average time to humeral head migration as determined by an AHI above 7 mm (superior migration), 6.61 mo (SD=9.67) in the aortograft group whereas 4 mo (SD=4.33) in the nonaortograft group. A poor track record regarding stability was estimated with proximal humeral endoprostheses historically. However, the aortograft group inclined towards a longer time to proximal humeral migration but no significant improvement was reported in the functional range of motion.
