The Polar Bear has proportionally wider scapulae (89% vs 75%) , larger deltopectoral crests ( 69% vs 56% ) and acromion processes (21% vs 18%) than Arctodus based on this study :

It's possible that the short faced bear had proportionally longer scapulae but these percentages suggest that Polar bears have overall stronger shoulders than short faced bears of similar size.
