Congenital hidden spinal cleft refers to a gap in the lumbar sacral vertebrae, where the cauda equina nerve and the dura mater protrude, adhere, and become fixed through the gap. When these nerves are pulled, tensed, ischemic, and produce symptoms such as frequent urination, urgency, incontinence, constipation, fecal incontinence, muscle atrophy of the gastrocnemius muscle, high arches, and clubfoot, even paralysis of the lower limbs may occur. Mild symptoms like enuresis can be treated conservatively without rushing for surgery; however, if symptoms are severe, such as incontinence of urine and feces, surgery should be performed as soon as possible to achieve better results. It is recommended to seek professional advice from pediatric neurosurgery.
