Whiplash “Anatomy.”

20 Dec

To better understand Whiplash, let’s take a look at the anatomy and what is actually injured in a whiplash injury.  Our spine is basically a long chain made up of blocks that are larger at the bottom and smaller at the top. This means the low back vertebra are huge compared to the neck vertebrae. The vertebrae fit together in a way that “locks” them together by the small joints in the back called “facets” and in the front by the disks. These joints function as shock absorbers between the blocks or “vertebral bodies.” Also in the front, there is a tough piece of tissue called the “anterior longitudinal ligament” that provides a barrier so that when the neck is bent backwards (into “extension”), it becomes tight and stops that movement so it doesn’t over-extend, which could fracture the small facet joints in the back.

There are ligaments, or tissues that hold bone to bone, in the back of the spine that connect between the “spinous processes,” or bony “bumps” in the middle of the back. These ligaments check or stop excessive forward motion of the neck during whiplash. Joint capsules surround joints, which we all have seen when we separate a chicken leg from the thigh. Remember how smooth and shiny the end of the chicken leg is? That smooth surface at the end of long bones is call “hyaline cartilage”, and it allows for slippery gliding between the ends of our bones when we move any joint, including our fingers, wrists, shoulders, hip as well as the facet joints of the spine. Joint movement is facilitated by the presence of an oily substance called “synovial fluid” which acts like a lubricant for the joint allowing for pain-free movement.

A “sprain” occurs when we damage a joint capsule or a ligament, or when the muscle or its attachment (tendon) is injured. These are graded as mild, moderate or severe, or grades 1, 2,or 3, with grade 3 being the worst at 75% or greater tearing, and healing takes progressively longer with each grade.

During a whiplash injury, the classic rear-end collision results in over stretching of the ligaments in the neck, and tearing can occur (sprain, grades 1, 2 or 3). If one of the nerves gets pinched, then numbness, pain, and/or weakness can occur, radiating down the arm to a specific location. When this occurs, the long-term prognosis is worse. Concussion can also occur if the brain is slammed against the inside of the skull. Chiropractic adjustments, when administered early, yield the best results for treating whiplash, according to many studies.

Neck Pain Treatment Options.

14 Dec

Neck pain is a very common problem. In fact, 2/3rds of the population will have neck pain at some point in life. It can arise from stress, lack of sleep, prolonged postures (such as reading or driving), sports injuries, whiplash injuries, arthritis, referred pain from upper back problems, or even from sinusitis! Rarely, it can be caused from dangerous problems including referred pain during a heart attack, carotid or vertebral artery injuries, or head or neck cancer, but these, as previously stated, are very uncommon. However, since you don’t know why your neck hurts, it’s very important to have your neck pain properly evaluated so the cause can be properly treated and not just covered up from the use of pain killers!

Barring the dangerous causes of neck pain listed above, treatment methods vary depending on whom you elect to consult. Classically, if you see your primary care physician, pharmaceutical care is usually the approach. Medications can be directed at reducing pain (Tylenol, or one of many prescription “pain killers”), at reducing inflammation and pain (Aspirin, Ibuprofen, Aleve, etc.), to reduce muscle spasms (like muscle relaxers) or, medications may be directed to reduce depression, anxiety, or the like. When a sinus infection affects the 2 deep sinuses (ethmoid and sphenoid sinuses which are located deep in the head), the referred pain is directed to the back of the head and neck. Here, an antibiotic may be needed and/or something specifically directed at allergies when present. In general, in cases that do not respond to usual chiropractic care, co-management with the primary care physician is a good option.

However, the good news is that chiropractic care usually works well, and the need for medication can be avoided since the side effects of medication can sometimes be worse than the benefits. Recently, The Bone and Joint Decade Task Force on Neck Pain published arguably the best review of research published between 2000 and 2010 regarding neck pain treatment approaches. They concluded that spinal manipulation and mobilization are highly effective for many causes of neck pain, especially when arising from the muscles and joints – the most common cause. Therefore it would seem logical to consult with a Chiropractor FIRST since manipulation and mobilization are so effective and safe. When we add neck exercises, the results are even better, according to some studies. As chiropractors, we will often use different modalities including electric stimulation, ultrasound, hot and/or cold (which are usually given as a good home-applied remedy), and others. In particular, low level laser therapy (LLLT) has been shown, “…to reduce pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients with chronic neck pain” [Lancet, 2009; 374(9705)]. LLLT is a commonly used modality by chiropractors and when combined with spinal manipulation, the results can be even faster! We will also evaluate your posture, body mechanics, and consider “ergonomic” or work station problems and offer recommendations for improving your work environment. We also frequently utilize anti-inflammatory nutrients including vitamins, minerals, herbs, and more to avoid the negative side effects to the stomach, liver, and kidney negative that can result from using non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin, ibuprofen, or Aleve. Make chiropractic your FIRST choice when neck pain strikes, NOT last resort!

Neck Pain and Chiropractic.

12 Dec

Neck pain represents a major problem for people throughout the world with considerable negative impact on individuals, families, communities, health care systems, and businesses. Up to 70% of the general population will have neck pain at some point in their life. Recovery within the year from neck pain ranges between 33% and 65%, AND relapses are common throughout the life time of the neck pain patient. Generally, neck pain is more common in women, higher in high-income countries, and higher in urban regions. The greatest risk of developing neck pain occurs between 35 and 49 years of age. Since neck pain, very similar to low back pain, is very common and likely to recur over and over again, the question is, what is the best course of action regarding treatment?

A recent study on neck pain patients compared the effectiveness of manual therapy performed by a chiropractor, physical therapy performed by a physical therapist (PT), and medical care performed by medical physician (MD). The success rate determined at the seventh week was TWO TIMES BETTER for the manual therapy/chiropractic group (68.3%) compared to the medical care group. Those receiving manual therapy also had fewer absences from work compared to both the medical and PT treated groups. Lastly, both the manual therapy and PT groups used less pain relief medication compared to the medically treated group. Another study looked at the multiple approaches that chiropractors use for treating patients with neck pain to determine the “best” approach a chiropractor can use. They reported 94% had improvement or less neck pain after just one treatment when the mid-back (thoracic spine) was also adjusted. Similarly, after receiving two treatments over a one week time frame, the group receiving midback adjustments (vs. the group who did not) reported lower pain and disability scores. A similar study concluded that the best results occurred when the neck, upper back/lower neck, and mid-back were adjusted. This group, when compared to neck adjustments alone, reported greater reductions in disability scores. Thus, having the cervical spine, upper back, and mid-back all adjusted appears to yield quicker, more satisfying results than neck adjustments alone.

What about the role of exercise in the management of neck pain patients? In November 2012, a systematic review of manual therapies for nonspecific neck pain reported that the addition of neck exercises to a treatment plan provided more benefits than spinal manipulation alone. Similarly, in September 2012 (The Annals of Internal Medicine), chiropractic adjustments were compared against exercise and pain medication treatment groups involving 272 patients tracked over a one-year time frame after a 12-week treatment. Both the chiropractic and exercise groups experienced the most significant pain reduction when compared to the medication treated group with more than double the likelihood of complete pain relief. The chiropractic and exercise groups also had the best short and long term results, but ONLY the chiropractic group found the benefits to last a year or more. The authors (Bronfort, et. al) reported the success of chiropractic treatment stems from its ability to address the CAUSE of the problem rather than simply addressing the symptoms!

Whiplash “Basics.”

12 Dec

Whiplash is a non-medical term typically describing what happens to the head and neck when a person is struck from behind in a motor vehicle collision. Let’s look at some basic facts about whiplash:

Before cars, trains were the main source of whiplash and was called “railroad spine.”

Better terms for whiplash injuries include “cervical acceleration-deceleration” (CAD) which describes the mechanism of the injury, and/or the term “whiplash associated disorders” (WAD), which describes the residual injury symptoms.

Whiplash is one of the most common non-fatal injuries involved in car crashes.

There are over one million whiplash injuries per year due to car crashes alone.

An estimated 3.8 per 1,000 people per year have a whiplash injury.

In the United States alone, 6.2% of the population has “late whiplash syndrome” (symptoms that do not resolve at one year).

1 in 5 cases (20%) remain symptomatic at one year post-injury of which only 11.5% returned to work and only 35.4% of that number returned to the same level of work after 20 years.

The majority of whiplash cases occur in the fourth decade of life, females>males.

Whiplash can occur from slips, falls, and brawls, as well as from horse-riding, cycling injuries, and contact sports.

Injury from whiplash can occur at speeds of 15 mph or less.

In the “classic” rear end collision, there are four phases of injury (time: 300msec)

Initial (0msec) – before the collision (the neck is stable)

Retraction (1-150msec) – “whiplash” starts where the head/neck stay in the original position but the trunk is moving forwards by the car seat. This is where the “S” shaped curve occurs (viewing the spine from the side).

Extension (150-200msec) – the whole neck bends backwards (hopefully stopped by a properly placed head rest).

Rebound (200-300msec) – the tight, stretched muscles in the front of the neck propels the head forward immediately after the extension phase.

We simply cannot voluntarily contract our neck muscles fast enough to avoid injury, as injury to the neck occurs within 500msec. and voluntary contraction or bracing takes 800msec or longer.

Injury is worse when the seat is reclined as our body can “ramp” up and over the seat and headrest. Also, a springy seat back increases the rebound affect.

Prompt treatment is better than waiting for a long time. Manipulation is a highly effective (i.e., COME SEE US!) treatment option.

We realize you have a choice in where you choose your healthcare services.  If you, a friend or family member requires care for whiplash, we sincerely appreciate the trust and confidence shown by choosing our services and look forward in serving you and your family both presently and in the future.

Neck Pain – Where Is It Coming From?

10 Dec

Neck pain can arise from a number of different tissues in the neck. Quite often, pain is generated from the small joints in the back of the vertebra (called facets). Pain can also arise from disk related conditions where the liquid-like center part of the disk works its way out through cracks and tears in the thicker outer part of the disk and can press on nerves producing numbness and/or weakness in the arm. It is possible to “sprain” the neck in car accidents, sports injuries, or from slips and falls. This is where ligaments tear and lose their stability resulting in excessive sliding back and forth of the vertebrae during neck movements. When muscles or their tendon attachments to bone are injured, these injuries are called “strains” and pain can occur wherever the muscle is torn. There is also referred pain. Here, the injury is at a distance away from where the pain is felt. A classic referred pain pattern is shoulder blade pain when a disk in the neck herniates. Let’s take a closer look at two conditions we often diagnose and treat as chiropractors:

Spinal Stenosis: This occurs when the canals in the spine narrow to the point of pinching the spinal cord in the trefoil shaped central canal (called “central stenosis”) or when the nerve roots get pinched in the lateral recesses (called lateral recess stenosis). This can occur from arthritis in the facet joints, disk bulging or herniations, thickening of ligaments, shifting of one vertebra over another, aging, heredity (being born with a narrowed canal), and/or from tumors. Usually, combinations of several of the above occur simultaneously. When this is present in the neck, it can be more serious compared to stenosis in the low back as the spinal cord ends at the upper part of the low back (T12 level) so only the nerves get pinched. Stenosis in the neck however pinches the spinal cord itself. Symptoms can include pain in one or both arms, but it’s more dangerous when leg pain, numbness, or weakness occur (called myelopathy). Rarely, loss of bowel or bladder control can occur which is then considered a “medical emergency” and requires prompt surgery.

Cervical Disk Herniation: As previously stated, the liquid-like center of the disk can work its way through cracks and tears in the outer layer of the disk and press on a nerve resulting in numbness, pain, and/or weakness in the arm. The classic presentation is the patient finding relief by holding the arm over the head, as this puts slack in the nerve and it hurts less in this position. The position of the head also makes a difference as looking up usually hurts more and can increase the arm pain/numbness while looking down reduces the symptoms. We will carefully test your upper extremity neurological functions (reflexes, muscle strength, and sensation as each nerve performs a different function in the arm), and we can tell you which nerve is pinched after a careful examination. This condition can lead to surgery so please take this seriously.

The good news is that chiropractic care can manage both spinal stenosis and cervical disk herniations BEFORE they reach the point of requiring surgery. So make chiropractic your FIRST choice when neck pain occurs!

Whiplash Diagnosis.

10 Dec

Whiplash is, by definition, the rapid acceleration followed by deceleration of the head causing the neck to “crack like a whip” forwards and backwards at a rate so fast that the muscles cannot react quickly enough to control the motion. As reported last month, if a collision occurs in an automobile and the head rests are too low and/or seat backs too reclined and the head moves beyond the allowable tissue boundaries, “whiplash” injury occurs.

When gathering information from the patient, this portion of the history is called “mechanism of injury” and it is VERY IMPORTANT, as it helps us piece together what happened at the time of impact. For example, was the head turned upon impact? Was the impact anticipated? What were the weather conditions (visual, road conditions)? What was the direction of the strike (front, rear, side, angular, or combinations of several)? Did a roll over occur? Was a seat belt used (lap and chest) and were there any seat belt related injuries (to the low back/pelvis, breasts/chest, shoulder, neck)? Any head impact injuries with or without loss of consciousness (if so, how long)? Any short-term memory loss and residual communication challenges (post-concussive syndrome)? All of the answers to these questions are very important when determining the examination path, establishing the diagnoses, and determining the treatment plan.

We also discussed last month the WAD classification or, Whiplash Associated Disorders, which was coined in 1995 by the Quebec Task Force. Types I, II, and III are defined by the type of tissues injured and the history and examination findings. In 2001, the Quebec Task Force found that WAD II (loss of range of motion or ROM/negative neurological findings) and WAD III (both ROM loss and neurological loss) carried progressively greater risk of prolonged recovery compared to WAD I injuries (those with pain but no loss of motion or neurological findings).

Establishing a strong diagnosis allows for accuracy in prognosis and treatment plan recommendations. For example, in WAD II & III injuries, flexion/extension x-rays are needed to determine the extent of ligament damage as normally, the individual vertebrae should not translate or shift forwards or backwards by more than 3.5mm. Similarly, the angle created between each vertebra in flexion & extension should be within 11 degrees of the adjacent angles, and if that’s exceeded, ligament damage is likely to have occurred. So often, ER records describe little to no information about the historical elements reviewed in the 1st paragraph and if x-rays were taken, they rarely include flexion/extension stress x-rays.

Headaches are another component of WAD. Here, the first three sets of nerves that exit the uppermost levels of the spine (C1, C2, and C3) innervate the head. When a patient describes headaches that start in the upper part of the neck and radiate up into the head, the distribution of the pain by history can tell us which nerve(s) are most affected. In the examination, applying manual pressure to the base of the skull can reproduce pain when a nerve is injured. Tracking these findings on a regular basis can tell us how the condition is healing. Chiropractic is at the forefront of diagnosis for WAD!
