2022年4月17日 · Adult Spinal Deformity is an idiopathic or degenerative condition of the adult spine leading to a deformity in the coronal or sagittal plane. Diagnosis is made with full-length spine radiographs. Treatment is a trial of nonoperative management with …

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.

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.” During a PSO, your doctor will remove (or subtract) a number of bony structures.

Pedicle Subtraction Osteotomy is a surgical procedure performed on the spine to correct severe spinal deformities, such as excessive kyphosis or scoliosis. It involves removing a wedge-shaped section of bone from the vertebral body and posterior elements to realign the spine into a more normal position.

2022年4月5日 · Smith-Petersen osteotomy. This specific technique corrects lordosis. By removing a section of bone from the back of your spine, your spine leans more toward the back. Pedicle subtraction osteotomy. This surgery corrects more severe (greater arching) lordosis in your lower spine. Bone-disk-bone osteotomy.

2020年2月6日 · 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 …

the pedicle subtraction osteotomy. Figure 2. The short rods control the osteotomy closure as well as prevent translation while finishing the osteotomy. Figure 3. The short rods hold the osteotomy correction during placement of the long rods and are independent of the long rods.

2016年7月24日 · Pedicle subtraction osteotomy (PSO) is a posterior-based osteotomy that requires resection of the posterior elements, pedicles, and decancellation of the vertebral body in a V-shaped fashion through the transpedicular corridor (FIG 1B).

Lumbar pedicle subtraction osteotomy (PSO) is indicated in the treatment of large sagittal (more than 25 of rigid loss of lordosis) deformities of the lumbar spine or its combination with coronal deformity, especially when they are rigid.

A pedicle subtraction osteotomy (PSO) surgery aims to restore the balance in the sagittal plane by increasing the lordosis between 30 to 40 degrees. Performing this complex surgery is associated with major challenges. Leveraging Medtronic procedural solutions is a key advantage for limiting the risks and makes this operation a success ...
