Biopsychosocial Model for a Multidisciplinary Perioperative Care Pathway in Patients Undergoing Posterior Spinal Fusion Surgery for Adolescent Idiopathic Scoliosis

Surgical correction of adolescent idiopathic scoliosis (AIS) is indicated for severe deformity. Posterior Spinal fusion (PSF) for AIS is one of the most invasive orthopedic surgical procedures in children and adolescents, often characterized by a large surgical incision, extensive tissue trauma, risk of blood loss, longer operating times and severe postoperative pain. In addition to pain, the postoperative period is complicated by the side effects of opioids such as nausea and vomiting, itching and sedation. All of this can, along with under-treatment of postoperative pain, be an important delaying factor in postoperative recovery and rehabilitation with a late hospital discharge and increased patient dissatisfaction. Various studies have shown that pain in the direct postoperative phase is an important determinant for development of chronic post-surgical pain.

The consequences of untreated pain are known and can also contribute to chronification in pain.

The incidence of chronic post-surgical pain after scoliosis fusion is 22% at 6 months and 11-15% at 1 to 5 years postoperatively. It is therefore important to minimize the pain during the first postoperative days. Untreated pain in patients is far from benign with significant negative short and long term consequences with accompanying reduction in rehabilitation duration, sleep quality of life. To date, there is no scientific evidence that some analgesic policy is superior, making adequate and safe pain relief and associated anti-emetic therapy after PSF a challenge makes for all healthcare providers involved.
