Youth sports participation in the United States has increased dramatically over the past two decades — as has the incidence of sports-related foot and ankle injuries in children and adolescents. While many youth athletes with foot injuries are told to “rest it” and return when pain improves, several common pediatric sports injuries have specific anatomic vulnerabilities that require accurate diagnosis and targeted management to prevent complications that affect long-term function.

Growth Plate Injuries Are Unique to Children

The most critical distinction between adult and pediatric sports injuries is the growth plate. Open physes (growth plates) in children are the weakest point in the bone-tendon-ligament chain — they fail before the ligaments do. What produces a ligament sprain in an adult may produce a Salter-Harris fracture through the growth plate in a child. This is why an ankle “sprain” in a child with point tenderness over a growth plate must be X-rayed to exclude a growth plate fracture — even if the mechanism seems trivial.

Most Common Pediatric Sports Foot and Ankle Injuries

Sever’s Disease (Calcaneal Apophysitis)

The most common cause of heel pain in active children 8–14 years. The Achilles tendon pulls on the still-ossifying calcaneal growth plate during running and jumping — producing posterior heel pain that worsens with activity. Treatment: heel cups, Achilles stretching, activity modification. Full resolution guaranteed at skeletal maturity. See our complete Sever’s disease guide for detailed management.

Lateral Ankle Sprain

Ankle sprains are among the most common sports injuries in children and adolescents — but require growth plate X-ray evaluation to exclude a distal fibula Salter-Harris I or II fracture (which is frequently missed and presents identically to a lateral ankle sprain). Point tenderness over the fibular physis (growth plate) rather than the ATFL ligament suggests fracture rather than sprain. Grade 2–3 sprains in adolescents benefit from formal rehabilitation to prevent chronic instability.

Fifth Metatarsal Apophysitis (Iselin’s Disease)

The equivalent of Sever’s disease at the fifth metatarsal base — the peroneus brevis tendon attachment on the fifth metatarsal apophysis becomes irritated in active children 8–13 years during sports with lateral cutting. Lateral midfoot pain with activity, tenderness at the fifth metatarsal base. Distinguished from fifth metatarsal avulsion fracture by age and X-ray. Treatment: lateral wedge in footwear, activity modification, stretching.

Osteochondral Lesions of the Talus (OLT)

Talar dome cartilage injuries occur in adolescents after significant ankle sprains or cumulative microtrauma. Persistent deep ankle aching, swelling, and intermittent clicking after an ankle injury that “should have healed” raises concern for an OLT. Missed in approximately 30% of initial evaluations — MRI is required for diagnosis. Smaller lesions respond to rest and physical therapy; larger lesions may require arthroscopic treatment.

Stress Fractures

Metatarsal and navicular stress fractures occur in adolescent runners and multisport athletes — particularly in the context of the “Female Athlete Triad” (disordered eating + menstrual dysfunction + low bone density). Dorsal forefoot pain that progressively worsens with training warrants imaging. The navicular stress fracture is particularly important to diagnose accurately — it is poorly visible on plain X-ray and requires MRI or CT; it heals with non-weight bearing but risks displacement and non-union if undertreated.

Return-to-Play Principles

Safe return to youth sport follows a staged progression, not a fixed time period:

• Complete rest from sport until walking is normal and pain-free
• Straight-line running without pain before cutting or jumping
• Sport-specific drills (cutting, jumping, contact) without pain before returning to practice
• Full practice before returning to competition

Returning a child to sport before completing these stages — simply because “the time is up” or parental/coaching pressure exists — produces re-injury and potentially worse outcomes than the original injury.
