Hockey Injuries at 13-17: Concussions, Growth Plates, and the Hits That Matter Most

Ice hockey is one of the fastest, most physically demanding sports a teenager can play. It is also, statistically, the most dangerous team sport for concussions in youth athletics. If your 13-17 year old plays competitive hockey, this is what you need to know — not to scare you out of the sport, but to ensure they play it safely and for as long as they want to.

The Concussion Problem Is Bigger Than You Think

Hockey leads all team sports in youth concussion incidence — ahead of football, soccer, lacrosse, and rugby. The USA Hockey safety program tracks concussion data across age groups and consistently finds that the 14U-18U age brackets carry the highest risk. Why? Because this is when body checking becomes legal (Bantam/14U and above), players are bigger and faster, and the gap between early and late developers creates significant size mismatches on the ice.

The developing adolescent brain is uniquely vulnerable to concussive injury. Research published in the British Journal of Sports Medicine shows that young athletes take longer to recover from concussions than adults — with some teens experiencing symptoms for weeks or months after a single concussion. The "just a ding" mentality that pervades hockey culture at every level is actively dangerous in youth settings.

Growth Plates: The Hidden Vulnerability

Between ages 13 and 17, the growth plates (physis) in a teenager's bones are still open and actively growing. These growth plates are structurally weaker than the surrounding bone, ligament, and tendon tissue. In an adult, the same force that causes a ligament sprain may cause a growth plate fracture in a teenager. This matters enormously in hockey because of the types of forces involved: body checks against boards, collisions with other players, and falls onto hard ice surfaces.

The most commonly affected growth plates in hockey are the wrist (distal radius), the shoulder (proximal humerus), and the knee (distal femur and proximal tibia). A growth plate injury that is misdiagnosed as "just a sprain" and left untreated can cause abnormal bone growth, limb length discrepancies, and permanent joint problems. Any persistent pain near a joint in a growing hockey player warrants X-ray evaluation — not ice and ibuprofen.

The Five Most Common Hockey Injuries at 13-17

1. Concussions. From body checks, falls, collisions, puck strikes, and board contact. The most consequential injury category by far. Every suspected concussion requires immediate removal from play and medical clearance before return.
2. Shoulder separations (AC joint) and dislocations. Typically from board contact or checking. In teens, the clavicle growth plate may fracture rather than the ligament tearing. Shoulder injuries account for approximately 15% of all hockey injuries in the 15-17 age group.
3. Knee injuries — MCL and ACL. Knee-on-knee contact, awkward falls, and rotational forces on planted skates. MCL sprains are more common than ACL tears in hockey, but both occur. Female hockey players face ACL risk at rates comparable to other cutting sports.
4. Wrist and hand fractures. Falls onto outstretched hands on ice. Scaphoid fractures are notoriously difficult to diagnose initially and can have serious complications if missed. Any wrist pain after a fall that persists beyond 48 hours needs imaging.
5. Hip flexor strains and groin pulls. The skating stride places enormous demand on the hip flexors and adductors. Rapid direction changes, explosive starts, and the sustained skating position create chronic loading that leads to overuse injuries. These account for roughly 10-12% of all hockey injuries in teens.

Common Mistakes That Increase Risk

• Playing through pain. Hockey culture glorifies toughness. But a 14-year-old with growth plates still open is not a professional athlete. Pain is information, and in growing bodies, it's often a growth plate or overuse injury announcing itself.
• Ignoring size mismatches. A 13-year-old who weighs 95 pounds body checking with a 16-year-old at 170 pounds is a physics problem, not a character-building exercise. Coaches must manage contact drills with size/maturity awareness.
• Year-round single-sport hockey. Playing 60-80+ games per year plus summer camps and showcases is the definition of overuse. Research consistently links early sport specialization with higher injury rates and earlier burnout.
• Helmet fit and condition. A helmet that's too big, too old, or improperly fitted provides dramatically less protection. Helmets should be replaced every 3-5 years or after any significant imp...
