Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
V. Strang, D.C., describes several hypotheses on how a misaligned vertebra may cause interference to the nervous system in his book, Essential Principles of Chiropractic: [24] Nerve compression hypothesis: suggests that when the vertebrae are out of alignment, the nerve roots and/or spinal cord can become pinched or irritated.
Spondylolisthesis is when one spinal vertebra slips out of place compared to another. [1] While some medical dictionaries define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it (or the sacrum), [2] [3] it is often defined in medical textbooks as displacement in any direction.
Then, the chiropractor adjusts the spine with a quick and precise thrust. This is done to improve mobility in the vertebral joints. Lumbar Roll (a.k.a. side posture)—The chiropractor positions the patient on their side, then applies a quick and precise manipulative thrust to the misaligned vertebra, returning it to its proper position.
As such, lordosis in the human spine is considered one of the primary physiological adaptations of the human skeleton that allows for human gait to be as energetically efficient as it is. [ 6 ] Lumbar hyperlordosis is excessive extension of the lumbar region, and is commonly called hollow back or saddle back (after a similar condition that ...
Retrolisthesis can be classified as a form of spondylolisthesis, since spondylolisthesis is often defined in the literature as displacement in any direction. [1] [2] Yet, medical dictionaries usually define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it (or the sacrum).
The severity of symptoms of damage to the iliohypogastric nerve can show whether damage occurred above or below the anterior superior iliac spine. [6] Bone may be harvested from the nearby iliac crest for use elsewhere in the body. [5] As the subcostal nerve lies close to the anterior superior iliac spine, this is put at risk of damage. [5]
Spinal posture is the position of the spine in the human body. It is debated what the optimal spinal posture is, [ 1 ] and whether poor spinal posture causes lower back pain . [ 2 ] Good spinal posture may help develop balance, strength and flexibility .
