  1. Ankle and Leg Injuries ROP SPORTS MEDICINE Stacy Camou

  2. Skeletal Anatomy • Talus • Tibia • Medial aspect • Larger of the two leg bones • Second longest bone in body • Primary weight bearing bone in leg • Fibula • Lateral aspect • Functions to provide muscle attachments • Non-weight bearing

  3. Skeletal Anatomy

  4. Articulations • Talocrural joint = Ankle joint • Made up of the tibia, fibula, and talus • Talus is wedge shaped • Lateral malleolus extends more distally than the medial malleolus • Proximal to Distal tibiofibular joint is connected by • Syndesmosis Joint (HIGH ANKLE SPRAIN)

  5. Articulations- Talocrural Joint

  6. Articulations

  7. Musculoskeletal Anatomy • 4 Compartments of the leg • Anterior compartment (most commonly Injured) • Tibialis anterior • Extensor hallicuslongus • Extensor digitorumlongus • Peroneus tertius • Anterior tibial artery and vein • Deep peroneal nerve • Lateral compartment • Peroneus longus • Peroneus brevis • Superficial peroneal nerve

  8. Musculoskeletal Anatomy • Compartments of the leg • Deep posterior compartment • Tibialis posterior • Flexor hallucislongus • Flexor digitorumlongus • Posterior tibial artery and vein • Tibial nerve • Superficial posterior • Gastrocnemius • Soleus • Plantaris

  9. Musculoskeletal Anatomy

  10. Ankle Medial aspect Deltoid ligament Thick and strong Lateral aspect Anterior talofibular Posterior talofibular Calcaneofibular Leg Proximal and distal anterior and posterior tibiofibular ligaments +Interosseous membrane = Syndesmosis Ligaments Ligamentous Anatomy

  11. Ligamentous Anatomy

  12. Gastrocnemius Tibialis Anterior Soleus Achilles Tendon Peroneus Longus Peroneus Brevis

  13. Fractures • Avulsions • Piece of tibia/fibula is pulled off by ligament • Fairly common • X-rays for all ankle sprains

  14. Fractures

  15. Fractures • Tibia • Traumatic fractures are serious due to size of bone • Stress fractures • Medial tibial stress syndrome • “shin splints” • Fibula • Fairly common • Non-weight bearing; competition possible • Stress fractures • Reasonably common due to muscle attachments • Both bones • Usually requires surgery to stabilize

  16. Fractures

  17. Strains • Gastrocnemius/Soleus strain occurs: • Muscle belly • Musculotendinous junction • Anterior extensors strain • Often called “shin splints” (lateral to tibial ridge) • M.O.I = Hill, climbing, or speed work • May lead to chronic compartment syndrome • Toe flexors • Often called “shin splints” (medial to tibial ridge) • M.O.I = Pronation increases odds • Achilles tendon • Strain vs tendonitis ( can lead to rupture )

  18. Strains • Achilles tendon rupture • Most common over 30 years old • Chronic history of inflammation or • Acute Sudden push off • Signs and symptoms • “I was kicked in the back of the leg!!” • Immediate pain • Palpable defect • Positive Thompson’s test

  19. STRAINS

  20. Thompson’s Test

  21. Sprains • Lateral ankle sprains • M.O.I = Inversion/plantar flexion mechanism • Most common injury in body • 90-95% of all ankle sprains occur to lateral ligaments…..Why? • Strong medial ligaments • Fibular block • Ligaments involved • Anterior talofibular or ATFL • Calcaneofibular or CFL • Posterior talofibular or PTFL • Mild to severe grades (1°-3°)

  22. Lateral Ankle Sprain

  23. Sprains • Medial ankle sprains • M.O.I = Eversion mechanism • Rare (5%) occur medially….WHY???? • Strong deltoid ligament • Fibular block • Deltoid ligaments Injured • Graded Mild to severe (1°-3°) • Syndesmosis sprain • M.O.I = Forced dorsiflexion and/or eversion • “High ankle sprain” • Slow to heal • Anterior tibiofibular (ATFL) ligament and interosseous membrane are the ligaments injured

  24. Medial Ankle Sprain

  25. Other Conditions • Achilles tendonitis/tenosynovitis • Inflammation of the tendon or sheath surrounding the tendon • Causes hypertrophic scarring Achilles Tendon Rupture

  26. Achilles Tendonitis

  27. ACHILlES TENDON RUPTURE

  28. Other Conditions • Compartment syndrome • Typically anterior or deep posterior compartments • Acute • Caused by direct blow or injury within fascial compartment • Medical emergency • Taut, shiny appearance of skin • Foot drop if advanced • Requires surgical decompression • Chronic • Muscle hypertrophy during exercise • Decreased space in compartment • Slow, continual rise in temperature • Treatment???

  29. If pressure is too high surgery will be required.
