[|AI|]  Thank you for sharing your query on Chat Doctor, I have carefully worked through your case, the babies with shoulder dystonia can develop temporary or permanent complications, the most common of these injuries are damage to the brachial plexus nerves, the potential long-term consequences depend on the nature and extent of the injury. Fortunately most brachial plexus birth injuries are transient, the majority of such injuries resolve by 3 months, with a range of 2 weeks-12 months, only a 4 to 15 % result in some degree of permanent injury such as hand muscle imbalance, deformities of the shoulder and elbow and the compromised arm can be 10 cm shorter than the nonaffected arm.  Please kindly rate if my advice has been helpful Wishing you a good health Chat Doctor.
