I had left clavicle fractured 3 months ago, kept hand sling for 6 weeks, but still fractured clavicle is same as that of first day, fractured parts are displaced one over the other. Will it remains as it is, is there any chance of reunion of fractured parts ,or it is ok for displaced parts to remain as such. Shoulder is stiff and there is very less movement of hand, plz suggest some good exercises for normal movement of hand.
