Let's suppose that you have been diagnosed as getting a pinched nerve in your neck, also recognized as cervical radiculopathy. If so, you probably have discomfort in the neck and one particular shoulder. The pain may possibly radiate into your arm and you may have weakness or numbness in the arm as well. Moving your neck in certain positions almost certainly worsens the discomfort.

If you happen to be a younger adult, the pinch could be due to a herniated (slipped) disc. Discs are the soft spacers that separate each pair of stacked neck-bones (vertebrae). If you are an older adult, the pinch is a lot more most likely due to a bony spur (spondylosis). In either situation, you happen to be in good firm. A survey in Sicily showed 3.5 active instances at any one time of cervical radiculopathy per population of 100,000. In Rochester, Minnesota, an additional survey showed 85 new circumstances every year of cervical radiculopathy per population of 100,000.

Let's say that your doctor has evaluated you thoroughly by taking a background of your signs and symptoms and performing a physical examination. Probably with the further support of an MRI of your cervical spine (neck) and electrical tests of nerve and muscle function (nerve conduction studies and electromyography) the diagnosis of cervical radiculopathy is deemed definite. In addition, there is no sign that the spinal cord itself is pinched. Now what?

Now what, indeed. Choosing a therapy for this situation is far from straightforward. Out of hundreds of published medical reports concerning therapy of cervical radiculopathy, most are case reports or situation series. A "case series" translates roughly as: "We gave six sufferers in a row the exact same remedy and five of them got better." What can be concluded from a study of this sort? Did the therapy make the patients better or would they have improved anyway? We do not know.

The missing ingredient right here is a comparison group of untreated or differently treated people recognized as a control group. The other mark of a quality study is that the selected therapy is randomized, which means that the analysis subjects agreed in advance to be assigned to 1 treatment group or another based on the equivalent of a coin-toss. So out of the hundreds of published research involving therapy of this common situation, how a lot of have been randomized controlled trials? Sadly, the answer is just one particular.

Liselott Persson, Carl-Axel Carlsson and Jane Carlsson at the University Hospital of Lund, Sweden, randomly allocated 81 patients who had signs and symptoms of cervical radiculopathy present for at least three months to any of three therapies -- surgery, physical therapy or a cervical collar. The patients ranged from 28 to 64 years old and 54% of them were male. The surgeons employed the so-called Cloward process, removing fragments of protruding discs and spurs via an incision in the front of the neck, and then fusing two neck-bones with each other by means of a bone-graft. Physical therapy involved 15 sessions more than a span of 3 months and consisted of whatever the physical therapist considered suitable, variously like any of the following: heat application, cold application, electrical stimulation, ultrasound, massage, manipulation, exercising and education. In the cervical collar group, patients wore rigid, shoulder-resting collars every day for three months. Moreover, some of the subjects wore soft collars overnight.

How did the study turn out? 3 of the subjects who had been assigned to surgery refused the procedure due to the fact they had currently improved on their personal. For statistical purposes their outcomes had been integrated with these who actually received the operation. Immediately after three months the surgery and physical therapy groups reported, on average, less pain. After an further 12 months sufferers in all 3 groups had less discomfort than at the beginning of the study and the outcomes of each treatment have been statistically alike. Measurements of mood and all round function following therapy have been likewise equal amongst the groups.

So, over the extended haul, no therapy was far better than the others. Of course, within each and every group some patients did far better or worse than other people and this spread of outcomes was not reflected in the overall averages. In fact, 5 patients in the collar group and one particular patient in the physical therapy group went on to receive surgery owing to lack of satisfactory improvement. In addition, eight sufferers in the surgery group underwent a second operation that in a single case was due to a complication of the 1st operation.

With this Swedish study representing the only rigorous investigation of remedy outcomes in cervical radiculopathy, there are a quantity of unanswered questions. For example, what are the effects on cervical radiculopathy of painkillers, anti-inflammatory drugs, regional injections, systematic traction or other types of surgery? We don't know. What occurs if there is no remedy whatsoever? We do not know the answer to that question either.

Therefore, in the care of person sufferers there is a yin-yang balancing act among the medical edict of "Above all, do no harm" and the practical dictum of "Do what you have to do." This balancing act generally means beginning with much less intrusive therapies like drugs and physical therapy. If symptoms fail to improve or turn into unbearable, an operation may possibly be useful.
