Occult fracture of the lumbar 5 vertebrae is not a very serious disease and usually does not produce significant symptoms and does not require special treatment. Often patients are found during physical examinations or after an injury, occult fractures generally do not cause neurological symptoms and do not produce obvious instability of the lumbar spine, unless the patient suffers an acute injury, chronic strain, or other factors of bone metabolism that cause the invisible fracture to worsen, resulting in spinal instability and symptoms, at which point treatment is required. Generally speaking, invisible fracture does not produce obvious symptoms, does not require special treatment, and is not a very serious disease. Patients should pay attention to the protection of the lumbar region in daily life to prevent injuries, strains and other accidents, and to avoid adverse stimuli such as cold.
