On an x-ray, you can tell if somebody is still growing based on the presence or absence of growth plates at specific, known locations within the bone. If the growth plate is still very wide-meaning lots of distance from the rest of the bone on either side of the growth plate-then the child is younger. As a child ages, the growth plate narrows, until eventually it is just a thin line between two parts of that bone, and eventually it becomes invisible all together. At this point, the bone is done growing.
We classify fractures involving the growth plates using something called The Salter-Harris classification. There are five subtypes of classifications, increasing in severity of injury and problems to the bone with increasing number. Fortunately, most growth plate fractures are a type 1 or type 2 Salter-Harris fracture – which is the most mild kind. While it is possible to have disruption or problems related to future growth with any type of growth plate fracture, fortunately they are pretty uncommon for type one and two fractures. Also, most kids sustain a type one or type two fracture as well – not the more serious types (3-5).
So – in short, if you or your child sustained a fracture to the growth plate, do not necessarily worry! Get it checked by somebody who is comfortable treating orthopedic injuries in kids of all ages. Most of the time, this is the more mild type involving a type one or two fracture. Most of these do not have any long-term sequela to the injury. Also, bones can tolerate being a little bit angulated, or crooked, particularly in very young kids. Their bodies know to grow the bones straighter overtime. The younger the patient, the more crooked the bone could be; there are certain specific parameters that we measure based on age and the x-ray. The growth plate is weaker than the ligaments, tendons, or remainder of the shaft of the bone, so this is where most injuries occur. Chances are, your child will heal up just fine and be back at it in no time!
Tommy John himself was a successful baseball player in the 1970s and 80s for the Los Angeles Dodgers and the New York Yankees. His fame truly derives from the fact that his career appeared to be in jeopardy when he sustained an injury to his inner elbow at the UCL. At that time, no professional major-league baseball pitcher had ever returned to play after having sustained this significant injury.
Behind the treatment and pioneering work of Dr Frank Jobe, John had surgery and ultimately returned to continue playing baseball – and had several more exceptional years. From here, other players also began to have this surgery and henceforth the procedure known as “Tommy John” refers to elbow ligament reconstruction in athletes.
The incidence of Tommy John injuries is rising. Of even greater concern is the fact that injuries are happening not only more frequently but to younger athletes. It is estimated that more than 55% of all pictures in the major and minor leagues have had Tommy John surgery.
Research has provided insight into the mechanism of injury. These include some of the following: year-round throwing, failure to adhere to established pitch counts and pitch limits, initiating curveballs at an early age or before mastery of fastballs and breaking balls, poor throwing mechanics, and others.
Throwing athletes of all ages should see a sports medicine elbow specialist if they are having elbow pain or a decrease in velocity when throwing. An experienced physician can help sort out the diagnosis as well as provide next steps for treatments or rehabilitation.
