Abstract: The patient presented with lumbar pain and limited movement after an inadvertent fall, and was diagnosed with a lumbar spine fracture by MRI. After comprehensive analysis, the patient was advised to take conservative treatment to make the symptoms less severe, and the patient agreed to be admitted to the hospital for conservative treatment. Through bed rest and lumbar back muscle exercise, the patient’s lumbar pain disappeared and the range of motion of the lumbar spine was completely restored. [Basic information] Male, 80 years old [Disease type] Lumbar fracture [Hospital] Harbin First Hospital [Consultation date] December 2021 [Treatment plan] Conservative treatment (bed rest, lumbar back muscle exercise) [Treatment period] 7 days of inpatient treatment, 1 month of outpatient follow-up [Treatment effect] Lumbar pain disappeared and lumbar range of motion was fully restored I. Initial interview The patient accidentally fell during walking, causing his hip to land on the floor. The patient fell and landed on her buttocks, causing lumbar pain and limited movement, but did not show symptoms such as weakness of both lower limbs and dysfunction of urination and defecation, etc. The diagnosis of lumbar fracture was confirmed by MRI. The patient’s spinal nerve was not compressed, and considering that the stability of the lumbar spine was still acceptable, the patient was advised to take conservative treatment to reduce the symptoms. In this case, surgical treatment could not guarantee complete restoration of the vertebral height, and the surgery itself could easily cause side damage to the tissues around the lumbar spine and affect the patient’s recovery. After the fracture of the lumbar vertebra, the patient’s clinical symptoms, such as lumbar pain and restricted lumbar movement, were the main manifestations, so conservative treatment was considered to relieve the clinical symptoms and promote recovery. In the process of conservative treatment, the patient was required to stay in bed for 2 months without sitting up or leaving the bed, and after the pain symptoms were alleviated, he started to perform lumbar back muscle exercises in bed, such as swallow flying exercises, to enhance the stability of the lumbar spine. 2 months later, he wore a lumbar brace and gradually left the bed for activities, and still insisted on bed rest daily. 3 months after the injury, he removed the lumbar brace and gradually resumed normal weight-bearing walking. Although the height of the lumbar spine was reduced, the degree of reduction was limited and the stability of the lumbar spine was still relatively ensured. The patient was discharged after 7 days of inpatient treatment and was followed up at the outpatient clinic for 1 month. 3 months later, the lumbar pain disappeared and the range of motion of the lumbar spine was fully restored, and the patient was able to resume normal life, work and light exercise without inducing lumbar pain, and the motor-sensory function of both lower limbs was not abnormal, and the neurological function was fully protected. IV. Precautions We are glad that the patient’s pain is relieved and the lumbar spine activity is restored after treatment. Patients should maintain continuous bed rest after discharge, and can leave bed after the review X-ray proves that the lumbar fracture is completely healed. Avoid premature weight-bearing activities, which will make the healing of the lumbar fracture site difficult, and even further compression of the lumbar vertebrae, and in serious cases, the lumbar fracture block will enter the spinal canal, causing damage to the spinal cord nerves and leading to serious consequences such as double lower limb paralysis. Patients with severe pain and weakness in both lower extremities should follow up with an orthopedic clinic in a timely manner to review MRI to confirm whether the spinal nerves are compressed, and if compression exists, surgery should be performed in a timely manner to save the nerve function. In addition, long-term adherence to lumbar back muscle exercise is essential to maintain the stability of the lumbar spine. V. Personal insight Lumbar spine fractures are mainly caused by traumatic causes such as falls, and osteoporosis is the pathological basis for the occurrence of lumbar spine fractures. In daily life, we should pay attention to both the prevention of trauma and the need to strengthen bone strength, and we can take some calcium supplementation drugs and insist on drinking milk every day to promote calcium absorption and calcium deposition. Also control diet, reduce weight, exercise muscles and strengthen lumbar spine protection, such as wearing a lumbar girth.
