Sacral 1 cryptorchidism does not require treatment if there are no obvious symptoms, but if the irritation of the nerves leads to dysfunction it requires surgical treatment. Sacral 1 cryptorchidism is a congenital developmental condition in which the sacral vertebral plate is not completely closed and cannot be seen on the surface of the body. Patients with sacral cleft 1 usually do not need treatment if they have no uncomfortable symptoms, as long as they avoid standing for a long time and heavy physical labor. If patients with sacral 1 occult fissure experience localized pain, soreness and swelling, they can be treated with localized hot compresses, and if the pain is obvious, they can use non-steroidal anti-inflammatory drugs, such as ibuprofen, to relieve the pain, or use a brace to protect them to reduce the stress on the painful area. If the patient develops symptoms of nerve irritation, such as intractable low back pain, surgical treatment is usually required. If a diagnosis of sacral 1 occultation is confirmed, the patient should actively cooperate with the doctor for treatment.
