Iatrogenic Deformity & Scoliosis
Deformity that develops after surgical procedures is termed iatrogenic. For instance, extensive laminectomy that destabilizes the facet joints of the lumbar spine can cause flatback or scoliosis. In flatback syndrome, the head of the patient is pitched forward and the person has difficulty looking straight ahead. As a result, the patient has to bend at the hips and knees in order to stand upright.
Occasionally, fusion surgeries if done improperly can cause imbalance and/or problems at the adjacent level of the spine. If this occurs, the patient may need revision surgery in order to correct the posture of the spine.
