There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal<unk>  nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal<unk>  nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle. Alternatively, or in addition to intraoperative procedures, postoperative procedures can also help in recovering the function of a damaged spinal<unk>  nerve. For example, the Eden-Lange procedure, in which remaining functional shoulder muscles are surgically repositioned, may be useful for treating trapezius muscle palsy.
