Injuries to the Lower Leg, Ankle and Foot 1 Bony Anatomy Bony Anatomy includes: Tibia, Fibula, Tarsals, Metatarsals, Phalanges 2 Bony Anatomy Medial view: tarsals and metatarsals 3 Medial Ligaments of Ankle Deltoid Ligament rarely injured in sports mechanism of injury typically eversion with dorsiflexion longer time to heal than lateral ankle ligaments 4 Lateral Ligaments of Ankle 3 primary ligaments: anterior talofibular posterior talofibular Calcaneofibular – NOT as large & strong as the deltoid. – Mechanism of injury is inversion associated with plantar flexion.5 Lower Leg Anatomy 3 Compartments – Anterior, Lateral, & Posterior 6 Fractures – Mechanism most often caused by direct trauma to the tibia, fibular or bone(s) of the foot repeated “microtrauma” can result in a stress fracture growth plate injures can occur in the adolescent -- known as “Salter-Harris” fractures – Signs/symptoms: swelling/deformity, discoloration broken bone end protruding athlete reports a snap/pop inability to bear weight stress fractures often become more painful at7 night – First Aid: Fractures treat for shock apply sterile dressing to any open wounds carefully immobilize using appropriate splinting technique contact EMS and arrange for transport 8 Ankle Fracture 9 Ankle Fracture 10 Ankle Dislocation 11 Ankle Sprains Details one of the most common injuries to this region Due to skeletal and ligamentous variables, lateral sprains are more common. 80-85% of all ankle sprains are to the lateral ligaments -inversion sprains Eversion sprains, while less frequent, are often severe. Syndesmosis Sprain: Sprain of the ligaments connecting the tibia and fibula. 12 Signs/symptoms: – 1st deg. -- pain, mild disability, pt. tenderness, little or no swelling – 2nd deg. -- pain, mild to moderate disability, pt. tenderness, loss of function, some laxity, swelling – 3rd deg. -- pain & severe disability, pt. tenderness, loss of function, laxity, severe swelling 13 Ankle Sprains First Aid: ice, compression and elevation apply a horseshoe or doughnut-shaped pad use crutches, partial or full weight bearing any questions regarding severity, refer to a physician for further evaluation and diagnosis 14 Ankle Sprain Prevention – Research indicates that taping is only good for a short period of time. Braces may be as effective as tape and at a much lower cost – Best prevention is to strengthen the muscles of the lower leg as well as develop proprioception. 15 Two examples of rigid ankle braces 16 Tib/Fib Syndemosis Sprain – Signs and Symptoms Often treated as lateral ankle sprain, which is inappropriate, hindering recovery. The difference is the mechanism of injury. Tib-fib sprains involve dorsiflexion followed by axial loading with external rotation of the foot. Symptoms – positive sprain test, but athlete is in great pain. Slower healing Sometimes physicians will cast. 17 Achilles Tendon – Achilles tendon commonly injured -- more often in older (30+) male athlete – can be either an acute or chronic, overuse injury – acute injuries often associated with blunt trauma – chronic injuries often associated with sudden increase in training intensity 18 Common Injuries Signs/symptoms – swelling and deformity – pop or snap – pain in lower leg – loss of function, especially in plantar flexion First Aid: – immediate application of ice and compression – immobilize with appropriate splint – arrange for transport to a medical facility 19 Torn Tendon 20 Achilles Surgery 21 Compartment Syndrome – usually involves the anterior compartment of the lower leg – Chronic form is related to overuse of the muscles of the compartment – Trauma, such as being kicked in the leg, can result in swelling within the compartment as well. – In either case, swelling puts pressure on vessels and nerves. 22 23 Compartment Syndrome Signs/symptoms/First Aid: – pain/swelling and loss of sensation and/or motor control in the lower – loss of pulse in the foot – inability to extend the big toe or dorsiflex the foot apply ice & elevate - do NOT apply compression – loss of pulse or sensation -- medical emergency - transport to medical facility 24 Shin Splints Signs/symptoms: – lower leg pain -- typically a chronic injury that progressively worsens – pain is often bilateral – “Shin splints” is generic pain in the lower legs, typically caused by change in surface or workout. First Aid: – apply ice and have the athlete rest – use of NSAIDs may be helpful – seek a professional to identify the cause 25 Foot Disorders Plantar Fasciitis – plantar fascia spans from the metatarsal heads to the calcaneal tuberosity Ball of foot to heel. – this tissue can become inflamed and painful – painful in the morning when first rising from bed – point tenderness in the region of the calcaneal tuberosity 26 Common Injuries Heel Spurs – often related to chronic plantar fasciitis – involves ossification at the site of attachment to the calcaneus Treatment of Plantar Fasciitis and Heel Spurs – rest and NSAIDs – stretching of the Achilles – doughnut pad beneath the heel spur 27 Common Injuries Morton’s Neuroma – growth (enlargement) of the interdigital nerve usually between the 3rd and 4th metatarsal heads – pain will radiate into the 3rd and 4th toes – tight fitting shoes have been identified as a major causative factor – going barefoot often relieves the symptoms – the neuroma may have to be treated surgically 28 Common Injuries Care for Neuroma – Teardrop pad can be placed between met heads to increase space, decreasing pressure on neuroma – Shoes with wider toe box would be appropriate – the neuroma may have to be treated surgically 29 Common Injuries Foot disorders Arch problems – two groups of arch problems: pes planus and pes cavus – Pes Planus = flat arch – Pes Cavus = high arch 30 Common Injuries – corrective taping may provide temporary support for the arch – In some cases, the athlete may benefit from a properly constructed orthosis. – Orthotics should be constructed by a trained professional. 31 Common Injuries Blisters & calluses – very common formations, result from friction between layers of skin – when a blister forms, fluid collects between skin layers, occasionally the fluid will contain blood – if the blister is large, it should be drained – When draining a blister, use sterile instruments, latex gloves and eye protection 32
