Abstract

The purpose of surgery for adolescent idiopathic scoliosis, which characteristically includes thoracic hypokyphosis and all three columns of the spine, is the achievement of a balanced spine while preserving as many motion segments as possible and avoiding neurologic damage. Many approaches have been defined in the treatment of this common disease. Posterior-only surgery, instrumentation and fusion have become the preferred technique in many centers throughout the world due to simplicity of approach, decreased risk of certain complications and the correction power of pedicle screws. This review attempts to summarize the advantages and disadvantages related to posterior instrumentation and fusion in adolescent idiopathic scoliosis.

Keywords: Deformity; Idiopathic; Posterior instrumentation; Scoliosis; Surgery; Vertebra.

Fig. 1
a, b 16 year-old girl with Lenke type 5CN adolescent idiopathic scoliosis. Instrumentation of only the structural curve using a posterior approach was sufficient for the nonstructural curve to correct spontaneously. Postoperative images show excellent correction and overall alignment

Fig. 2
a, b 15 year-old girl with Lenke type1B- adolescent idiopathic scoliosis. Patient has a very prominent preoperative right thoracic hump which required thoracoplasty despite derotation and correction using a pedicle screw-only construct. Postoperative images show excellent alignment

Fig. 3
a, b 14 year-old girl with Lenke type 1AN adolescent idiopathic scoliosis. Note the prominent right thoracic hump preoperatively. Posterior-only surgery was performed using a pedicle screw-only construct. Note correction of thoracic hump without the need for thoracoplasty. This indicates three-column fixation and successful derotation using pedicle screws
