In the last few decades, the concept of sagittal balance has gained importance in spinal surgery. It guides decision-making for orthopedic and neurosurgeons. Its impact on patient outcomes, however, has been less clear. Let's examine a few of the recent advances in spinal surgery. In this article, we'll discuss the correction of sagittal imbalance and posterior discectomy.
Surface-EMG
The goal of surface-EMG and sagittal balance in spine surgery is to determine the strength of spinal muscles. Sagittal balance is the result of improper alignment of the spine. Often times, muscle contraction occurs to compensate for the spinal sagittal imbalance. However, this compensatory movement can result in pain and fatigue. Surface-EMG and sagittal balance in spine surgery provide a way to measure the strength of spinal muscles in real-time.
Gait analysis - best spine surgeon in india
In spinal surgery, gait analysis plays an important role. In the lumbar spinal stenosis, the most common cause of spinal surgery, gait analysis provides the surgeon with important information about the patient's walking patterns. This can lead to improved decision-making regarding the treatment of this condition. Currently, doctors make diagnosis and treatment decisions based on physical examination, MRI and CT scans, and patient's history. However, with the development of new computer tools, gait analysis may become a valuable clinical decision-making tool.
Correction of sagittal imbalance
Correcting sagittal balance in spine surgery is a dynamic process that involves rebalancing the sagittal plane. A long fusion can produce undesirable adjacent segment disease and limit the rebalancing capacity of the spine. Correcting sagittal imbalance may require multiple procedures. Listed below are surgical techniques to correct sagittal imbalance in spine surgery. The techniques include anterior-posterior fusion, pedicle subtraction osteotomy, and fusion with instrumentation.
Posterior discectomy
Sagittal balance refers to the relationship between the sagittal plane and the lumbar column. A patient with sagittal imbalance may experience pain and discomfort in the lumbar region. This is because of direct compression of the lumbar pars interarticularis by the inferior facets of the L4. Additionally, some patients have morphological differences that cause their sagittal plane to be out of balance and require correction surgery.
BDBO
The BDBO has received considerable attention in spinal surgery due to its potential role in the correction of deformity. However, there are some important limitations of the procedure. For example, osteotomies of the type 1 and type 2 sagittal deformities are not symmetric. Therefore, PSO should be reserved for type 2 deformities. Nevertheless, the PSO can be performed on type 2 deformities.
