Abstract Upper extremity injuries consist of a wide range of presentations, from small skin wounds to severe injuries that require replantation and reconstructive surgeries. Herein we present a hemi-amputation and crush injury to the upper extremity in a 7-month-old-infant following a motor vehicle accident which led to a replantation and reconstructive procedure. A replantation and reconstruction procedure was performed under general anesthesia. A month later, a wrist disarticulation procedure was performed due to necrosis. The bones were fixed with two pins. The following muscles and tendons were repaired: flexor digitorum profundus (tendons of the digits 4 and 5), extensor carpi radialis brevis, extensor carpi ulnaris, and flexor carpi ulnaris. Right radial and ulnar arteries were anastomosed and a splint was used to protect the injured limb. After a 6-month-follow-up, on the examination of the upper limb proximal to the wrist, the sensory examination including tactile, pain, temperature, and vibration sensation was normal.
