Summary
Scoliosis is a structural, tridimensional deformity of the spine. Characterized by lateral
curvature and rotation of the vertebrae with functional limitations and cosmetic problems,
idiopathic scoliosis, which accounts for 75% to 80% of all scoliosis, is the most common of
all types. (1, 2) Surgical treatment is an effective way to correct severe spine deformity
when the deformity progressively worsens and cannot be positively corrected by brace
treatment. Spinal correction surgery is one of the most invasive surgical procedures and
usually results in moderate to severe levels of postoperative pain. (3) Severe pain may
induce implant complications such as construct dislodgement, broken instrumentation, and
implant loosening which requires additional revision procedures These conditions adversely
affect postoperative outcomes.(4) In the past several years, pain has become an important
indicator for evaluating indicators of outcome and quality of life after surgery. Effective
analgesia after surgery could improve patients' prognosis.(5) The erector spinae block is a
recently described ultrasound-guided technique in which local anesthetics is injected into a
fascial plane between the tips of the thoracic transverse processes and the overlying erector
spinae muscle (longissimus thoracis).(6) The available evidence indicates that erector spinae
block is effective in reducing opioid requirements and improving the pain experience in a
wide range of clinical settings. They are best employed as part of multimodal analgesia with
other systemic analgesics
