Pain and discomfort in lower leg caused by (overuse)
- Tibialis Anterior and posterior most commonly implicated
- Increased risk of stress fractures and compartment syndrome if left untreated
- Changing footwear and a conservative treatment approach works best
Medial Tibial Stress Syndrome (Shin Splints
Runs from the calcaneal tuberosity to the heads of the metatarsals
•Acts as a “spring” during gait to propel people forward
Plantar Fasciitis
Thick connective tissue that supports the arch
Plantar fascia
Chronic injury •Pronation •High arches or flat feet •Overweight •Poor footwear •Tight triceps surae •Pain typically closer to the heel •Pain generally the worst getting out of bed in the morning •Conservative treatment works well •PT •Footwear •Night splint •Cortisone injection when symptoms become too much
Plantar fascia
Most common type of ankle fracture
•Swelling, bruising and point tenderness
•Pain at night
•Need an X-Ray to confirm
Lateral Malleolus Fracture
Named after Jacques Lisfranc de St. Martin
Caused by direct impact or sudden rotation force on a plantar flexed forefoot
•In athletics, tend to be most common in sports that have bindings
Lisfranc Fracture
Outpouching of intestinal tissue through the abdominal wall near the inguinal ligament
Pain when coughing, exercising or bending over
Sharp pain
•Usually needs to be corrected via surgery
