Vertebral compression fractures occur when the normal vertebral body of the spine is squeezed or compressed. The bone collapses when too much pressure is placed on the vertebrae, resulting in pain, limited mobility, loss of height, and spinal deformities. In severe compression fractures the vertebral body is pushed into the spinal canal which will apply pressure on the spinal cord and nerves.
Vertebral fractures results from weakened spine caused by osteogenesis imperfecta, osteoporosis, tumor, and trauma. Osteogenesis imperfect is a hereditary disease resulting in bone fragility. It is an autosomal dominant disorder of connective tissue that is characterized by easily fractured bones.
Your child may experience severe pain in the back which worsens on standing or walking and decreases when resting. Other symptoms include, weakness, and numbness in the affected areas, disability, limited spinal mobility, and loss of overall height. The symptoms which indicate multiple fractures in the spine are hunch back, bulging stomach, shortness of breath, hip fracture, and gastrointestinal problems. Children's who sustain multiple compression fractures may have hunch back (kyphosis or "dowager's hump"), gastrointestinal problems, hip pain, and shortness of breath.
Your doctor may require diagnostic tests such as X-ray, MRI scan, and bone scan which help to determine and confirm the fracture.
The treatment for vertebral compression fractures aims at reducing the pain, stabilizing, and repairing the fracture. The non-surgical measures include medications, back braces, bed rest, and certain exercises.
Nonsteroidal anti-inflammatory drugs may be prescribed to relieve bone, muscle and nerve pain. A back brace may be suggested to support the back and immobilize the movements.
Surgery may be needed if the pain still persists despite of non-surgical treatment. There are two minimally invasive surgical procedures for treating vertebral compression fractures are:
- Kyphoplasty: In this procedure a deflated balloon called as bone tamp is injected into the spine. The balloon is inflated until it expands to a desired height. The created space is then filled with Orthopaedic cement called polymethylmethacrylate. This procedure helps to restore the height of the vertebrae and reduces the deformity.
- Vertebroplasty: This technique involves injecting a cement material called polymethylmethacrylate, into the collapsed vertebra. The injected cement hardens quickly stabilizing the fracture, relieves pressure, and prevents further collapse.
The following measures may be practiced to decrease the risk of developing vertebral fractures:
- Teach your child some good techniques for standing, sitting, lifting, and housework activities.
- Do not encourage your child to lift heavy things, jumping, diving, horse riding, sliding, and amusement rides
- Ensure that your child wears seat belts in cars
- Make sure that your child avoids sitting at the back of the school bus
- Make sure that your child does not carry heavy book bags to school
- Exercise regularly. Swimming provides movement of joints without being stressed and is also good for the muscles at the back
