Fixed Sagittal Imbalance

Fixed Sagittal Imbalance (FSI) or Flat Back is a spinal deformity in which the spine does not curve normally but rather appears to be flattened. A spine has three types of curves; the lordotic (inward curve near the neck or above the pelvis), Kyphotic (outward curve near the rib cage) and the scoliotic (sideways curve). The curves in the spine form an “S” shape and are designed to balance the body as well as head. In Fixed Sagittal Imbalance, there is an absence of lordotic curve above the spine or the kyphotic curve near the rib cage, resulting in a flat back.  This posture exerts additional pressure on the buttocks, legs as well as thighs and can greatly hinder the normal life of a person.  

Causes Of Fixed Sagittal Imbalance

  • Osteoporosis- This disease weakens the bones causing spinal deformity
  • Degenerative Disc Disease- It leads to shortening of the spinal cord height and consequent loss of curvature
  • Ankylosing Spondylitis- Inflammatory disease that leads to stiffness and Arthritis of the spinal cavity
  • Fracture in the spine
  • Consequence of spinal surgeries such as Scoliosis or Stenosis
  • Age related degeneration of the spinal vertebrae
  • Severe Spondylolisthesis

Symptoms Of Fixed Sagittal Imbalance

Diagnosis Of Fixed Sagittal Imbalance

  • Evaluation of the patient’s medical history

Treatment For Fixed Sagittal Imbalance

The treatment may depend on the age, level of tolerance, medical history of the patient as well as the severity of deformity. These may include:

  • Physical therapy comprising of a combination of aerobics, core muscle training and weight training
  • Medication may be prescribed to provide relief from pain
  • Wearing a removable brace to support the spine and maintain a proper posture
  • Osteotomy which is the surgical removal of a part of the bone to create a curvature
