Foot, Ankle and Lower Leg Problems MS3 Family Medicine
Objectives • Define relevant anatomy, physiology, and radiographic features of the foot, ankle and lower leg • Recognize history, presenting signs and pertinent exam findings of common problems • Review treatment of common problems
Tibia Fibula Talus Dome Neck Calcaneus Medial tubercle Anterior process Posterior process Ankle Bones
What are these things? • Fractures • Sesamoids • Joint crystals • Phleboliths
Dorsal foot • Extensor tendons • Dorsal pedis artery • Digital nerves
Plantar Foot • Plantar fascia • Longitudinal collagen fibers • Medial calcaneal tubercle • Proximal phalanges • Plantar nerves
Midfoot Congruity • Tarsometatarsal Articulation (Lisfranc) • Transverse ligaments
Physical Examination“MSK BIG-6” • Inspection • Palpation • Range of motion • Strength • Neurovascular • Special Tests
Which foot is overpronated? • A • B • C • D D A B C
Normal Ankle X-ray AP Lateral Mortise
Acute Foot and Ankle Injuries • Bone • Ligament • Muscle Tendon • Nerve – Blood Vessels • Remember mechanism of injury!
Case # 1 • 26 yo male with ankle pain • Landed on foot while playing basketball • Stopped playing • Lateral pain • Able to limp off court and into your office
Case #1 History • Previous history: several prior sprains • Previous rehabilitation: minimal • Ankle protection: none recently • Ability to bear weight: yes • Neurovascular symptoms: no
Case #1 Physical Exam • Inspection: • Able to walk • Swelling, slight bruising laterally • Palpation: TTP ant-distal to LatMall, but not on bone • ROM: decreased DF, PF, Inv, Ev • Strength: mild decrease • Neurovascular intact • Special Tests: • Drawer: normal • Talar tilt: normal
Which of the following would indicate need for an x-ray? • Unable to bear weight • Tender over posterior lateral malleolus • Tender over posterior medial malleolus • Tender on navicular bone • Tender on 5th MT base • All of the above
Ottawa Ankle RulesWhen to x-ray acute ankle sprains • Unable to bear weight • Tender over posterior lateral malleolus • Tender over posterior medial malleolus • Tender on navicular bone • Tender on 5th MT base
Lateral Ankle Sprains • Grade 1 – Ligament stretch • Grade 2 – Ligament partial tear • Grade 3 – Ligament complete tear
What is the treatment for a Grade 1-2 lateral ankle sprain? • RICE rehab • RICE brace rehab • RICE cast • Surgical repair of the ATFL
Lateral Ankle Sprain • Treatment • PRICEMM: Protect, rest, ice, compress, elevate, Meds • Brace for 1-3 months during activity • Gradual ROM exercise • Physical Therapy • ROM • Strength • Proprioception
Case #2 • 34 yo male football player • Right ankle rolled up under him during tackle • Walked off field • Unable to return to play
Case #2 History • Previous history: neg • Previous rehabilitation: n/a • Ankle protection: none • Ability to bear weight: yes • Neurovascular symptoms: none
Case #2 Physical Exam • Inspection: • Difficulty bearing weight • Mild swelling around ankle med/lat • Palp: TTP laterally, anteriorly, medially • ROM: full • Strength: mild decrease • Neurovascular intact • Special Tests: • Painful Tib-Fib Squeeze • Painful ankle external rotation
High Ankle SprainAKA • Pain proximal to ankle • Painful ExtRot test • Painful squeeze test • ORDER xrays • Rule out mortise widening • Rule out fractured proximal fibula • Treatment: • Wide mortise: SURGERY • Normal xrays: cast 2-4 weeks >5mm
Case 3 • 24 yo ROTC student c/o aching in medial calves during running for 6 weeks • Goes away w/ 1-2 days rest, but lasting longer with time • Training for marathon
Examination • Normal appearing legs/ankles/feet • Palp: TTP diffusely medial tibial edges, distally • ROM: normal ankles (maybe tight heel) • Strength: normal • Neurovascular: normal • Special tests: • Fulcrum test normal
What’s your diagnosis? • Compartment syndrome • Medial tibial stress syndrome • Stress fracture • Tibial sadness syndrome
Etiology Muscle-bone junction traction injury Risk factors: ??? DDx Stress fracture Exertional compartment syndrome Treatment Cease painful activity Non-painful activity Physical therapy referral Ankle strength ex’s Heel stretches Orthotics Consider compression sleeve Medial Tibial Stress SyndromeAKA “shin splints”
Case #4 • 45 yo Male with chronic, insidious posterior heel pain • Worse after volleyball or running • Pain for several months • Difficulty walking, but warms up
Case #4 Differential Diagnosis • What lives in the back of the leg? • Calcaneus • Calf muscles • Gastrocnemius • Soleus • Achilles Tendon • Retrocalcaneal bursa
Evaluation • Inspection: thickened Achilles tendon • Palpation: very tender Achilles w/ thickened nodularity • ROM: limited DF from tight heel cords, o/w normal at ankle • Strength: normal • Neurovascular: normal • Special Tests: • Negative Thompson test
Achilles Tendinosis • Treatment • Reduce painful activities; alternate training activities • Physical Therapy modalities for acute pain control • Heel lift and BID heel cord stretches • Eccentric strengthening: • 90% success rate; takes time • Avoid steroid injection • Failures (>3 mos) • Refer to Sports Med
20 yo female kickboxing instructor Injured foot 2 days ago while kicking Walking painful, can’t jump or kick Whole foot hurts and is swollen Case 5
Examination • Swelling in midfoot, some ecchymosis • Very TTP dorso-medial midfoot • ROM: ankle normal, toes decr. • Strength: decreased toes • Neurovascular: normal • Special Tests: • Midfoot stress test OUCH • Ankle ligaments stable
WEIGHT-BEARING X-rays Non-weight bearing x-rays are normal
Lisfranc Complex Injury • 20% are missed on initial presentation • Treatment • Casting 2-6 weeks if NO FRACTURES OR INSTABILITY • Surgery for fractures or instability • CT/MRI/Bone Scan
Complications if Missed • Chronic pain • Arthritis • Inability to run or jump • Acute compartment syndrome
Case 6 • 59 yo female with plantar heel pain • Worse with first steps when getting out of bed • Gradually improves but worsens by end of day • Related to wearing boots
Examination • Valgus foot type (pronation, flatfoot) • TTP on sole at medial calcaneal tubercle • ROM: normal, but tight heel cords • Strength: normal • Neurovascular: normal • Special tests: neg
Plantar fasciitis (fasciopathy) • Treatment • Cease painful activity • Pain meds acutely • Ice, cross-friction massage • Prefab orthoses • (Physical therapy) • Plantar fascia stretching • Heel cord stretching • Tension night splint • Steroid injection
