What is a pedicle subtraction osteotomy?
A pedicle subtraction osteotomy (PSO) is a surgical procedure used in adults and children to correct certain deformities of the spine. A spine with too much kyphosis (forward curvature, or “hunchback”) or too little lordosis (inward curvature, or “swayback”) can be corrected with a PSO.
What is Smith Peterson osteotomy?
Smith-Peterson osteotomy (SPO) is described as an opening wedge osteotomy with a hinge at the posterior aspect of the disc space. This technique involves the resection of posterior elements, including bilateral facet joints, part of the lamina, and the posterior ligaments at the osteotomy site.
What is a posterior column osteotomy?
The posterior column osteotomy (PCO) is a tool for correction in spinal deformity. It allows for the induction of lordosis and coronal plane correction. It can be performed at multiple levels to loosen and mobilize the spine.
What is a vertebral column resection?
A vertebral column resection (VCR) is the complete removal of one or more vertebrae from the vertebral column. Vertebral column resection is used to correct certain spinal deformities in adults and children.
What is a 3 column osteotomy?
MC: “Osteotomy” literally means “to cut bone.” A “column” is roughly 1/3 of the width of the spine. Thus, the goal of three-column osteotomies is to break the spine in half without damaging the spinal cord. First, the back portion of the spine covering the spinal cord, known as the lamina, is removed.
Does back surgery make you shorter?
The surgery often adds to the patient’s over-all height. Growth will continue normally in the unfused portions of the spine as well as in the legs, arms, and other parts of the body.
A Pedicle Subtraction Osteotomy (PSO) is a form of surgical treatment that is used to reverse spinal deformities. As the name suggests, osteotomy means “to remove bone.”
What is an osteotomy of the back?
As the name suggests, osteotomy means “to remove bone.” During a PSO, your doctor will remove (or subtract) a number of bony structures. However, removal of the pedicles (a narrow strip of bone that connects the body of the vertebra to its back side) defines this process.
What is pedicle subtraction?
This alignment is called sagittal balance. Conditions like hyperkyphosis, ankylosing spondylitis, and flatback syndrome can put the body’s center of gravity too far ahead of the pelvis, resulting in sagittal imbalance. Pedicle subtraction osteotomy is one surgical option for treating sagittal imbalance.
Can a moderate amount of scoliosis be corrected with osteotomy?
A moderate amount of scoliosis can sometimes be corrected during a pedicle subtraction osteotomy. Spinal curvature is measured in degrees. For example, a side-to-side curvature of 10 degrees or more qualifies as scoliosis.
