- It seems the injury rate increases during growth spurts, but research is very limited.
Growing pains are common in children, yet the cause and treatment of growing pains are not well known. Some hypothesize growing pains occur from muscles pulling on bones creating discomfort. Others believe increase in bone size simply increases discomfort from an increase in mechanical pressure.
Growing pains are one type of "injury" during growth spurts. Specific adolescent injuries also exists, which I commonly see for Physical Therapy:
- Osgood-Schlatter's Disease: is a painful swelling of the bump on the upper part of the shinbone, just below the knee. This bump is called the anterior tibial tubercle. It is believed to occur in active children who's patella tendon pulls on the tibial tubercle.
- Sever's Disease: inflammation of the growth plate in the heel of growing children, typically adolescents. The condition presents as pain in the heel and is caused by repetitive stress to the heel and is thus particularly common in active children. It usually resolves once the bone has completed growth or activity is lessened.
- These are just a few common musculoskeletal injuries effecting children. Many other injuries can occur during growth spurts and parents for decades believe children have a higher injury risk during a growth spurt. Combine this injury risk with chronic poor posture from computers/electronics and early sports specialization and you've got a high injury risk for child...scary!
Growth Spurts and Injuries
Now, before we jump to conclusions about the injury incidence and growth spurts, we should consult
Yukutake (2014) had 654 baseball players aged 6-12 years, all male, complete an original questionnaire that included items assessing demographic data, developmental factors (increase in height and increase in weight over the preceding 12 months), and baseball related factors. Multiple regression analysis was used to identify the risk factors for elbow pain during the 12 months prior to the study.
The data collected for 392 players without omissions or blank answers were submitted to statistical analysis. The results found that 19.1% of Little League baseball players had experienced elbow pain in the 12 months leading up to the study. The analysis revealed that height and increase in height were risk factors that increased the risk of elbow pain after adjustment for demographic data, developmental data, and baseball related factors.
Wild (2012) looked at ACL injury rates in adolescent boys and girls, noting girls have a higher ACL injury rate from:
- The effects of changes in estrogen levels on the metabolic and mechanical properties of the ACL
- Changes in musculoskeletal structure and function that occur during puberty, including changes in knee laxity, and lower limb flexibility and strength.
- How these hormonal and musculoskeletal changes impact upon the landing technique displayed by pubescent girls.With limited research, limited conclusions are possible.
