Misconceptions about Back Pain

Misconceptions about Back Pain

It’s just a fact of life: as we age, our bodies just don’t work like they used to. And often, back pain is a common complaint. It’s not unusual for those suffering from back pain seek advice from family or friends before going to a doctor. Referrals can be great! But advice seeking can also lead to misconceptions about back pain and spine surgery.
Listed below are just a few of the misconceptions we’ve come across over the years. Have you been misled by any of these?
“The best way to deal with back pain is to rest until it goes away.”
Resting is not the only way to deal with back pain. In some cases limited activity may be necessary but you should try to keep moving as much as you can. Stretching properly helps keep your muscles active and can help you recover more quickly.
“If I have back pain, I must have injured my back in some way.”
                This is not necessarily true. There are a number of diseases that can cause back pain. Degenerative disc disease is a gradual process that commonly compromises the spine. The intervertebral discs in the lumbar spine are structures prone to the degenerative changes associated with wear and tear, aging, and misuse (e.g. smoking).
“Back pain happens to everyone as they get older.”
                While back pain is common and older patients are more susceptible, back pain can happen to anyone. From dogs to children to teens to adults to the elderly; anyone can be affected by back pain but it does not necessarily mean that they all will be. A healthy lifestyle and positive posture practice help keep the spine engaged, strong, and healthy.
“If I tell my doctor, they will try to get me to have surgery.”
                Research has found that in many cases physical therapy and exercising have helped relieve back pain. In some cases surgery may be necessary but it is not the only solution. Pain medication may also be administered as an attempt to avoid surgery.

ACL Risk – It’s In Your Genes

ACL Risk – It’s In Your Genes

Genes encoding proteoglycans are associated with the risk of anterior cruciate ligament ruptures
Mannion S, Mtintsilana A, Posthumus M, van der Merwe W, Hobbs H, Collins M, & Septemeber AV.  British Journal of Sports Medicine.  2014 Published Online First: doi: 10.1136/bjsports-2013-093201
Take Home Message: Individuals with a history of an anterior cruciate ligament injury are more likely to have certain genetic variations compared with individuals without a history of a knee injury. While these findings are novel and interesting, researchers need to conduct more research to understand the multifactorial genetic risk behind anterior cruciate ligament injuries.  
If we could identify factors that may predict who is at an increased risk for anterior cruciate ligament (ACL) rupture then we may be able to implement individualized injury prevention programs.  Genetic variants may change ligamentous properties, predispose an individual to an ACL rupture, and thus be an important risk factor for an ACL rupture.  Mannion and colleagues compared the presence of genetic variations between 227 individuals with an ACL rupture history and 234 healthy controls.  All of the participants were physically active and Caucasian. The authors also analyzed a subset of 126 individuals with a history of a noncontact ACL rupture.  They evaluated 10 genetic variants (single nucleotide polymorphisms) among 5 genes that encode proteoglycans, which influence the structural integrity of ligaments. Individuals with a history of ACL injury (34%) were more likely to have a genetic variation in a gene encoding aggrecan, a proteoglycan, compared with healthy controls (28%).  Females with a history of an ACL injury were also more likely to have variations in the gene encoding decorin, another proteoglycan, compared with female healthy controls. 
This is one of the first studies to investigate and identify genetic variations that may be related to a history of an ACL injury.  These findings help us understand that an ACL may be at more risk for injury due to changes in proteoglycans, which may alter the ligament’s tensile threshold.  At this point in time, this does not directly affect clinical treatments; however, these findings could inspire new interventions to address changes in proteoglycans and eventually help us identify individuals “at-risk” for an ACL injury.  This may help us prevent injuries by identifying athletes at risk and offering them individualized injury prevention programs.  While the authors showed that genetics may influence the risk of ACL injuries, it only focused on 10 variations of 5 genes.  Since the risk of an ACL injury is likely influenced by many genes, it may be advantageous to conduct genome-wide studies to encompass all of the possible genes and variations that influence the risk of ACL injury. We have repeatedly seen that genetic variations may influence the risk of injury and that it could influence how we practice but we’ll need to watch this area of research carefully to see how it unfolds.    
Questions for Discussion:  Do you think that genetic testing will change the future of athletic participation (e.g., prevention programs, withheld from certain sports)?  What if you had a patient or family member who tested positive for a genetic variation that made them more susceptible to an injury – would you still permit them to participate in activities that made the risk higher?
