Osteotomy: A Surgical Solution for Correcting Spinal Deformities
When conservative treatments fail to alleviate spinal deformities like kyphosis or scoliosis, osteotomy emerges as a potential surgical solution. Osteotomy involves surgically cutting and realigning the affected bone to correct the curvature and restore spinal balance.
Before undergoing osteotomy, patients typically undergo thorough evaluations, including imaging tests and physical examinations, to determine the extent and severity of the deformity. The goal of osteotomy is to achieve proper spinal alignment, reduce pain, and improve function.
Osteotomy is a complex procedure performed by a skilled spinal surgeon. The surgeon makes an incision along the affected area of the spine and carefully exposes the bone. Depending on the type of deformity, the surgeon may perform a vertebral column resection (VCR), a pedicle subtraction osteotomy (PSO), or a posterior closing wedge osteotomy (PCWO).
In VCR, the surgeon removes a portion of the vertebral column to correct the curvature. PSO involves removing a wedge-shaped portion of bone from the posterior (back) part of the vertebral body. And in PCWO, the surgeon removes a wedge-shaped portion of bone from the anterior (front) part of the vertebral body.
Once the bone has been realigned, the surgeon stabilizes the spine using screws, rods, and bone grafts. The bone graft promotes fusion between the realigned bones, ensuring long-term stability.
Osteotomy is generally a successful procedure for correcting spinal deformities. It can effectively reduce pain, improve spinal alignment, and restore function. However, as with any surgical procedure, there are potential risks involved, including infection, nerve damage, and blood loss.
Patients considering osteotomy should thoroughly discuss the risks and benefits with their surgeon and explore all other treatment options before making a decision. If successful, osteotomy can provide significant relief from spinal deformities and improve overall quality of life.
