An intervertebral disc has a gelatinous core surrounded by a fibrous ring.[32] When in its normal, uninjured state, most of the disc is not served by either the circulatory or nervous systems – blood and nerves only run to the outside of the disc.[32] Specialized cells that can survive without direct blood supply are in the inside of the disc.[32] Over time, the discs lose flexibility and the ability to absorb physical forces.[25] This decreased ability to handle physical forces increases stresses on other parts of the spine, causing the ligaments of the spine to thicken and bony growths to develop on the vertebrae.[25] As a result, there is less space through which the spinal cord and nerve roots may pass.[25] When a disc degenerates as a result of injury or disease, the makeup of a disc changes: blood vessels and nerves may grow into its interior and/or herniated disc material can push directly on a nerve root.[32] Any of these changes may result in back pain.[32]
Foraminotomy is an operation that “cleans out” or enlarges the bony hole (foramen) where a nerve root exits the spinal canal. Bulging discs or joints thickened with age can cause narrowing of the space through which the spinal nerve exits and can press on the nerve, resulting in pain, numbness, and weakness in an arm or leg. Small pieces of bone over the nerve are removed through a small slit, allowing the surgeon to cut away the blockage and relieve pressure on the nerve.
Imaging is indicated when there are red flags, ongoing neurological symptoms that do not resolve, or ongoing or worsening pain.[5] In particular, early use of imaging (either MRI or CT) is recommended for suspected cancer, infection, or cauda equina syndrome.[5] MRI is slightly better than CT for identifying disc disease; the two technologies are equally useful for diagnosing spinal stenosis.[5] Only a few physical diagnostic tests are helpful.[5] The straight leg raise test is almost always positive in those with disc herniation.[5] Lumbar provocative discography may be useful to identify a specific disc causing pain in those with chronic high levels of low back pain.[41] Similarly, therapeutic procedures such as nerve blocks can be used to determine a specific source of pain.[5] Some evidence supports the use of facet joint injections, transforminal epidural injections and sacroilliac injections as diagnostic tests.[5] Most other physical tests, such as evaluating for scoliosis, muscle weakness or wasting, and impaired reflexes, are of little use.[5]
It is unclear if among those with non-chronic back pain alternative treatments are useful.[84] For chiropractic care or spinal manipulation therapy (SMT) it is unclear if it improves outcomes more or less than other treatments.[18] Some reviews find that SMT results in equal or better improvements in pain and function when compared with other commonly used interventions for short, intermediate, and long-term follow-up;[19][20][85] other reviews find it to be no more effective in reducing pain than either inert interventions, sham manipulation, or other treatments, and conclude that adding SMT to other treatments does improve outcomes.[17][21] National guidelines reach different conclusions, with some not recommending spinal manipulation, some describing manipulation as optional, and others recommending a short course for those who do not improve with other treatments.[3] A 2017 review recommended spinal manipulation based on low quality evidence.[6] Manipulation under anaesthesia, or medically assisted manipulation, has not enough evidence to make any confident recommendation.[86]
Sciatica is a form of radiculopathy caused by compression of the sciatic nerve, the large nerve that travels through the buttocks and extends down the back of the leg. This compression causes shock-like or burning low back pain combined with pain through the buttocks and down one leg, occasionally reaching the foot. In the most extreme cases, when the nerve is pinched between the disc and the adjacent bone, the symptoms may involve not only pain, but numbness and muscle weakness in the leg because of interrupted nerve signaling. The condition may also be caused by a tumor or cyst that presses on the sciatic nerve or its roots.
There is controversy and scientific uncertainty about trigger points. It’s undeniable that mammals suffer from sensitive spots in our soft tissues … but their nature remains unclear, and the “tiny cramp” theory could be wrong. The tiny cramp theory is formally known as the “expanded integrated hypothesis,” and it has been prominently criticized by Quintner et al (and not many others). However, it’s the mostly widely accepted explanation for now. BACK TO TEXT
As has been highlighted by research presented at the national meeting of the American College of Rheumatology, a very important aspect of the individual evaluation is the patient's own understanding and perception of their particular situation. British researchers found that those who believed that their symptoms had serious consequences on their lives and that they had, or treatments had, little control over their symptoms were more likely to have a poor outcome. This research points out to physicians the importance of addressing the concerns and perceptions that patients have about their condition during the initial evaluations.
A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back, and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.
Low back pain (LBP) is a common disorder involving the muscles, nerves, and bones of the back.[4] Pain can vary from a dull constant ache to a sudden sharp feeling.[4] Low back pain may be classified by duration as acute (pain lasting less than 6 weeks), sub-chronic (6 to 12 weeks), or chronic (more than 12 weeks).[3] The condition may be further classified by the underlying cause as either mechanical, non-mechanical, or referred pain.[5] The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people completely better by six weeks.[2]
