VIDEO: PSO in flat back syndrome performed 38 years after Harrington instrumentation for AIS
In this video from Open Operating Theatre, Rune Hedlund MD, from Sahlgrenska University Hospital in Gothenburg, Sweden, treats a patient who was initially treated for adolescent idiopathic scoliosis and developed flat back syndrome 38 years later.
The video shows how pedicle subtraction osteotomy was performed at level 3. The wedge removed from the fusion mass, and so were pseudarthrosis and the pedicles. The Harrington rod that was originally used to treat the adolescent idiopathic scoliosis was mobilized to make a cut. Two connectors were used to connect the old rod with the new, stainless-steel rods. The hook at the bottom had gotten loose, so was removed. Blunt dissection was performed lateral to the vertebral body about 7 mm away from the anterior aspect of the vertebral body. Two transvers connectors were positioned away from the osteotomy.
This video is a teaching tool to help surgeons prepare for surgery or they can use it as refresher on the surgical technique and indications for this surgery.
