22 Sep Sagittal Imbalance may lead to higher risks of Vertebral Compression Fractures and Disc Degeneration – A Finite Element Analysis
The Sagittal balance is an important clinical parameter of the spine for its normal function.
Maintenance of the sagittal balance is crucial in the clinical management of spinal problems. Three different finite element models with spinal alignments based on Schwab’s classification were developed: A) Balanced/ Normal model (SVA=0 mm, LL=50̊, TK=25̊, PI=45̊, PT=10̊, SS=35̊); B) Balanced with compensatory mechanisms/ Flatback model (SVA= 50 mm, LL= 20̊, TK=20̊, PI= 45̊, PT= 30̊, SS= 15̊); C) Imbalanced/ Hyperkyphotic model (SVA=150 mm, LL=-5̊, TK=25̊, PI=45̊, PT=40̊, SS=5̊). All the three models were subjected to the follower loads simulating bodyweight/muscular contractions along with the moments to simulate flexion,extension, lateral bendings, and axial rotations. The maximum cortical vertebral stresses, annular stresses, and intradiscal pressures (IDP) were calculated and compared. The results
showed that the hyper-kyphotic model had higher stresses in the vertebrae (25% higher), the annulus fibrosus (48% higher) and the IDP (8% higher) than the normal models in flexion. The segments near the thoracolumbar junction (T10-L1) showed the highest increase in the vertebral body stresses, the annulus fibrosus stresses and the IDP. This showed that the imbalance in sagittal alignment might be responsible for disc degeneration and atraumatic vertebral fractures at the thoracolumbar regions, supporting the clinical findings.
Throughout our lives, we have physical stress on our body, some being acute such as falls, traumas, accidents and others which can be chronic such as sitting for long periods, working at a desk for long periods, using computers or phones or even just standing for long periods.
These physical stresses may cause us to lose our normal spinal alignment placing the spine in a weakened position.
At first, this causes no pain but, as the spinal structures are continuously abnormally loaded, they begin to break down leading to spinal damage and eventually the development of pain symptoms such as pain, numbness, weakness, stiffness and functional loss such as the inability to perform normal daily activities without difficulty.
At Sunset Chiropractic & Wellness nonsurgical drugless spinal and extremity treatments are selected and designed from a compressive consultation, health history, physical examination (orthopedic/neurological testing), digital posture analysis, weight bearing sitting x-rays using 41 measurements and 23 angles analyzing and comparing the spine to a mathematical model. In specific cases additional diagnostics could be ordered (Digital Motion X-rays/CTs/MRIs) to obtain or confirm a diagnosis.
Our team goes beyond conventional medicine by offering services and techniques which can relieve symptoms while at the same time addressing and resolving the underlying causes of your particular dysfunction.
Sunset Chiropractic and Wellness’s Structural Correction Chiropractic Care rehabilitate the damaged spine/extremities and its damaged structures (muscles, ligaments, fascia, discs, bone, and nerves) improving the structure and functions, reducing and removing the pain, and improving overall quality of life.
