A central Kentucky boy who survived being mauled by a pit bull over the summer is getting ready for reconstructive surgery.

Ten-year-old Garrett Carrier and his mother, Crystal Sims, told media outlets that during surgery this week a muscle will be taken from his back and used to reconstruct an armpit. In addition, nerves from his ankle will be moved to his arm and he'll get Botox injections to help firm up the muscles.

Sims says the surgery should significantly increase her son's range of motion with the arm, which was left dangling at his side after the attack and required more than 100 stitches to sew back on.

Sims says she is hoping her son's mental scars will heal along with the physical ones.
