Will I get Arthritis?

About 8 years ago I fell off a 50 ft roof and landed on my shoulder blade on a wrought iron gate which broke my fall. The force was such that 8 ribs on my left side at the front broke/snapped. They apparently don't try to reset broken ribs so now they are inter-joined, like slotted together. This still causes me pain when I lean forwards for short periods like dull ache which gets worse. Will I get arthritis when I get older? I'm 41 now.
