Use of Ultrasonic Bone Scalpel in Adolescent Idiopathic Scoliosis

Use of Ultrasonic Bone Scalpel in Adolescent Idiopathic Scoliosis - Randomized Clinical Trial

The primary purpose of this randomized trial is to compare the efficacy of an ultrasonic bone scalpel (or osteotome device) with standard of care surgical instruments during posterior spine fusion with instrumentation.

Inclusion Criteria:

1. 10-18 years of age
2. Diagnosis of Adolescent Idiopathic Scoliosis (AIS)
3. Scheduled for a posterior spinal fusion (without Schwab Grade II or higher osteotomy)

Exclusion Criteria:

1. Plan for a posterior column osteotomy of Schwab Grade II or higher
2. Prior spinal surgery
3. Magnetic Resonance Imaging (MRI) abnormalities (such as syrinx and/or chiari malformations)
4. Subjects with medical comorbidities (e.g. heart, lung, kidney disease)
5. Subjects with bleeding diatheses
6. Non-idiopathic etiology for scoliosis
