CASE 59 A 3-month-old boy, delivered by caesarian section, was brought to the pediatrician. The mother was concerned about the peculiar tilt of her son’s head. The pediatrician, after a brief examination, told the mother that her son had congenital torticollis and that it needed to be surgically corrected. WHAT IS THE CAUSE OF CONGENITAL TORTICOLLIS? As there was no birth trauma, the suspected cause of congenital torticollis is a deficient arterial blood supply to the sternocleidomastoid muscle during development. The resulting ischemia causes the underdeveloped muscle to be shorter than its fellow. In cases of birth trauma, fibers of the sternocleidomastoid muscle may be torn. As a normal response to injury, the damaged muscle fibers are replaced by fibrous tissue, which causes the muscle to be shorter than normal. THE AFFECTED MUSCLE CAN BE LENGTHENED BY SURGICAL DIVISION. WHERE SHOULD THE MUSCLE BE DIVIDED? Only gold members can continue reading.
