Ankle, Foot, & Lower leg introduction • 15% of all sports injuries involve the ankle. • More than 20,000 ankle sprains occur in the US everyday! • Most common reason for ER visits. • The foot stabilizes and supports the rest of our body during walking, running, and jumping. • There are 26 bones is the foot. • 7 Tarsals, 5 Metatarsals, 14 Phalanges Range of motion • Dorsiflexion • Plantarflexion • Inversion • Eversion • Flexion (toes) • Extension (toes) • Pronation (combined motions of calcaneal eversion, foot abduction and dorsiflexion) • Supination (combined motions of calcaneal inversion, foot adduction, and plantarflexion) Bony anatomy • Tibia • Fibula • Talus • Calcaneus • Navicular • Cuneiforms (1-3) • Cuboid • Metatarsals (1-5) • Phalanges (1-5) • Lateral/Medial Malleolus Arches of the foot • Transverse Arch – composed of the cuneiforms, the cuboid, and the 5th metatarsal. Arches of the foot • Lateral Longitudinal Arch – composed of the calcaneus, talus, cuboid, and 4th and 5th metatarsals. Arches of the foot • Medial Longitudinal Arch – the highest of the three arches; composed of the calcaneus, talus, navicular, cuneiforms, and the first three metatarsals. ligaments • Reminder - Ligaments connect bone to bone! • Lateral: • Anterior Talofibular • Calcaneofibular • Posterior Talofibular • Anterior Tibiofibular • Medial: • Deltoid ligaments Main Joints of the ankle • Reminder – Joints are where two bones articulate or meet! ① Talocrural Joint = Formed by the Tibia, Fibula, and Talus (hinge joint allowing plantar flexion and dorsi flexion) ② Subtalar Joint = Formed by the Talus and Calcaneus (eversion, inversion) Muscles moving the foot MUSCLE FUNCTION Gastrocnemius Plantar flexes foot, flexes leg Soleus Plantar flexed foot Tibialis Anterior Dorsiflexes foot, inverts and adducts foot Tibialis Posterior Plantar flexes foot, inverts and adducts foot Peroneus Tertius Dorsiflexes foot, everts foot Peroneus Longus Everts, plantar flexes foot Peroneus Brevis Everts foot Plantaris Plantar flexes foot Muscles moving the toes MUSCLE FUNCTION Flexor Hallucis Brevis Flexes great toe Flexor Hallucis Longus Flexes great toe Extensor Hallucis Longus Extends great toe, dorsiflexes foot Flexor Digitorum Longus Flexes toes, plantarflexes foot Extensor Digitorum Longus Extends toes, dorsiflexes foot Abductor Hallucis Abducts, flexes great toe Abductor Digiti Minimi Abducts little toe muscles Anatomy Summary • The foot has 3 arches – transverse, medial longitudinal, lateral longitudinal. • The foot has 26 bones – 7 tarsals, 5 metatarsals, and 14 phalanges. • The ankle joint is made up of the talocrural and subtalar joint. • There are 5 main ligaments in the ankle – anterior talofibular, anterior tibiofibular, calcaneofibular, posterior talofibular, and the deltoids. • https://www.youtube.com/watch?v=ROd1Acma64o • https://www.youtube.com/watch?v=4hCS1O2LP_c Ankle sprains • One of the most common injuries to the body. • Lateral Sprain - the most common type of sprain. • More than 80% of ankle sprains are lateral. • Involves injury to the lateral ligaments. • The anterior talofibular is the most commonly sprained ligament because it is the first lateral ligament that is stressed during inversion. • Eversion Sprain – less common. • Involves injury to the deltoid ligaments. Ankle sprains • Grade 1 (Mild): 1 or more ligaments are stretched. • Grade 2 (Moderate): 1 or more ligaments are partially torn. • Grade 3 (Severe): 1 or more ligaments are completely ruptured/torn. Ankle sprains • MOI (Mechanism of Injury): • Lateral Sprain = Excessive inversion • Eversion Sprain = Excessive eversion • S&S: • Mild – mild discomfort, point tenderness, little or no swelling, no joint laxity • Moderate – pain, swelling, point tenderness, loss of function, slight joint laxity. • Severe – pain, loss of function, point tenderness, rapid swelling, joint laxity. • Special Tests: Anterior Drawer, Talar Tilt, Kleiger Test Ankle sprains https://www.youtube.com/watc http://assets.sbnation.com/assets/2607549/curryankle.gif h?v=VolROn1613o Ankle sprains Ankle sprains Ankle sprain treatment • Immediate Treatment: • Protect – Splinting, taping, or bracing • Rest – Avoid activity, crutches if needed • Ice – 20 minute applications • Compression Wrap – controls swelling (horseshoe method) • Elevation – above the heart • Follow-Up Treatment: • Rehabilitation - ROM exercises, stretching, and strengthening Ankle sprain treatment Syndesmosis sprain • AKA High Ankle Sprain • Injury to the Anterior Tibiofibular Ligament • https://www.youtube.com/watch?v=-gKxAUyKF3c Syndesmosis sprain • MOI: Forceful dorsiflexion and external rotation. • S&S: • S&S are consistent with other sprain with the exception of • Pain and point tenderness between the distal tibia and fibula. • Special Test: Kleiger’s Test • Much longer healing process • https://www.youtube.com/watch?v=-nw7lRU223I Syndesmosis sprain Achilles tendonitis • The achilles tendon attaches the gastrocnemius and the soleus muscles to the calcaneus. • The gastrocnemius/soleus muscles give us the ability to plantarflex. • Tendonitis = inflammation of the tendon. • Overpronation makes an athlete more at risk. • MOI: Chronic injury due to excessive stress. • S&S: Symptoms will develop gradually. Pain and discomfort that becomes worse over time, possible crepitus. In extreme cases, the tendon will appear thickened. Achilles tendonitis treatment • Prevention!! • Maintaining flexibility of the achilles tendon will prevent injury. • Solve biomechanical problems such as overpronation. • Refer to a podiatrist (foot doctor). • Rest • Ice • Anti-inflammatory medication Achilles tendon rupture • Predisposing factors: Poor conditioning, decreased ROM of the achilles tendon, athletes over 30 years old, previous history (hx) of achilles tendonitis. • MOI: Forceful contraction such as a sudden push off or sudden force applied to a dorsiflexed foot. • S&S: • Will feel and hear a “pop” • Visible defect • Inability to stand on toes • Excessive passive dorsiflexion. • Special Test: Thompson Test • *Surgery is required to reattach the tendon* Achilles tendon rupture Achilles tendon rupture https:/ /www. youtub e.com/ watch? v=mZ H9Th MDq6 c Warm up ① Lateral ankle sprains are caused by what MOI? ② What ligaments are injured? ③ Medial ankle sprains are caused by what MOI? ④ What ligaments are injured? ⑤ What joint is formed by the talus and calcaneus? ⑥ What joint is formed by the tibia, fibula, and talus? ⑦ What joint allows inversion and eversion? ⑧ What joint allows plantar flexion and dorsi flexion? Great toe sprain (aka turf toe) • Great Toe = 1st Phalange • The great toe is important for balance, movement, and speed. • “Turf Toe” = a sprain to the ligaments supporting the great toe. • MOI: Hyperextension of the first metatarsophalangeal joint. • S&S: Pain, point tenderness, swelling, ecchymosis, limited mobility. Great toe sprain (aka turf toe) Great toe sprain (aka turf toe) • Treatment: • PRICE Method • When normal function is restored and the athlete is ready to RTP, use taping techniques to provide support/limit movement. Great toe sprain (aka turf toe) Plantar fascitis • Plantar Fascia = a wide, nonelastic ligamentous tissue that extends from the anterior portion of the calcaneus to the heads of the metatarsals. • Supports the longitudinal arches of the foot. Plantar fascitis • MOI: Chronic irritation of the plantar fascia causing inflammation. Examples….. • Running on hard surfaces • Unsupportive footwear • Repetitive running and jumping sports • Tight achilles tendon • S&S: Pain and point tenderness on the bottom of the foot near the heel. Plantar fascitis treatment • Correcting training errors • Evaluate athlete’s shoes and activity levels • Wear shoes with more arch support to help decrease stress • Ice • Massage • Taping techniques for arch support • Stretching Plantar fascitis treatment Medial tibial stress syndrome (Mtss) • AKA Shin Splints! • Chronic/Overuse injury • Inflammation of the periosteum (outer layer of bone). • Usually occurs on the distal third of the medial tibial border. • Typical in runners/jumpers. Medial tibial stress syndrome (Mtss) • Causes: • Tightness of the gastrocnemius/soleus. • Running on hard or uneven surfaces. • Poor footwear. • Excessive pronation. • Recent changes in running distances, speed, form, stretching, footwear, or running surface. Medial tibial stress syndrome (Mtss) • S&S: • Dull pain that begins at any point in the workout; occasionally may be sharp and penetrating. • Pain occurs along the medial border of the tibia in a 3-6 cm area; usually in the distal third. • Pain is relieved with rest, but may recur hours after activity stops. • Pain aggravated by plantar flexion. • In later stages, pain will be present before, during, and after activity and may restrict performance. Medial tibial stress syndrome (Mtss) • Treatment: • 5-7 days of rest to relieve acute symptoms. • Cryotherapy (Ice, Whirlpool, Ice massage) • NSAIDS (Anti-inflammatory medication) • Increase flexibility/strength in anterior and posterior musculature. • Analysis of running mechanics, foot alignment, running surface, and footwear. • If pain persists R/O stress fractures. Evaluation of the foot/ankle/ lower leg injuries H.O.P.S • H.O.P.S. • History – How did it happen (MOI), location of pain, previous hx.? • Observation – What do you see/observe? • Palpation – Palpate for crepitus, spasm, point tenderness, warmth, etc. • Special Tests – Assess ROM, Manual Muscle Tests (MMT) and Special tests. history Mechanism of Injury – Acute vs. Chronic? Example: How did the injury occur? Pain – Location, Type, Severity Example: Where is the location of your pain? What type of pain is it – sharp, dull, aching, tingling, numbness, burning? On a scale of 1-10 how bad is your pain? Did your hear a Snap, Crack, or Pop? What increases and decreases the pain? Do you have a previous history of injury? Do you have pain with certain motions? What sport do you participate in and what position? observation CHECKLIST: Observation = What you see or observe. Remember to compare bilaterally! (Compare the uninjured side to the injured side) Deformity Guarding Apprehension Swelling Ecchymosis Hematoma Abrasions Scars Atrophy palpation • Palpate bilaterally • Palpation Checklist: • Palpate ALL: Crepitus ①BONEY Structures Spasm ②SOFT Tissue Structures (Muscles, Tendons, Ligaments) Tension Point Tenderness Warmth Special tests ①Assess ROM in all directions ②MMT’s (Manual Muscle Tests) ③Special Tests: ROM • Ask the athlete to perform the appropriate ROM depending on the joint to the best of their ability (Example: Ankle = plantarflexion, dorsiflexion, inversion, eversion) • Check both extremities simultaneously, noting any differences. • The motion should be smooth and painless. • Limited ROM on one side indicates potential injury or deformity. Manual muscle tests MMT = manually testing an athlete’s strength to note any abnormalities due to injury. Compare the strength between the involved and uninvolved extremity to note any differences. Weakness on one side indications potential injury or deformity.
