Ankle Flashcards
Chronic ankle instability
Functional: Repeated lateral ankle sprains or one severe
Mechanical: Laxity in ligamentous structure-Pes cavus and decreased proprioception, decreased strength, and postural control
Episodes of ankle giving away
Tx: Stabilize calcareous at heel strike Limit rearfoot inversion External support Strengthening and proprioception ex Surgical intervention
Syndesmosis sprain
High ankle sprain Excessive ER of talus and forced DF MOI: cutting, being fallen on Usually occurs with medial ankle sprain Maison-neuve fx: force enough to fx fibula
S/S: Painful WB AROM restricted all-DF worse PROM pain all RROM all directions Pain and pt tender on anterior aspect of ankle
ST: Kleigers External rotation Squeeze Dorsiflexion-compression test (no pain with DF while compression is applied)
Tx:
Immobilize and NWB
Surgery may be necessary
Medial ankle sprains
External rotation and eversion
Excessive pronation, hyper mobile, depressed medial longitudinal arch more predisposed
Knock-off fx: evaluate lateral malleolus
Pott’s fx: bimalleolar fx
S/S: Pain along medial jt line Localized swelling NWB Abduction and addiction painful
ST:
Talar tilt
Kliegers
Tx: RICE NWB NSAIDS and Analgesics Proprioception ex Inner heel shoe wedge insert Surgery may be required
Medial tibial stress syndrome
Overuse or weakness of post tib, flexor hallicus/digitorum, or soleus muscles Abnormal biomechanics Improper shoes Pes planus, hyper pronated foot Activity and playing surface Direct blow Varus foot, tight heel cord, hypermobile, pronated foot, supinated foot Women more than men Precursor to stress fx
S/S:
Diffuse Pain at post, medial aspect of tibia that has a broad span
Increased pain w/activity that subsides during but comes on after but will start to stay throughout
gradual onset
Tx: Control pronation-orthotics and changing shoes Rest, ice, stretching Ice massage Arch taping and tape around the area
Stress fx
Can affect the tibia, fibula, and talus
Persistent micro trauma
Hypermobile pronated feet-fibula
Pes cavus-tibia
Narrow tibial shaft, high degree of hip external rotation, osteopenia, osteoporosis
Dreaded black line-anterior cortex of tibia prone to nonunion fx common with jumping
S/S: Pain w/activity that's better w/rest at first Decreased muscle strength and cramping Creptius Night pain Pt tender to single spot Gradual onset Pain in shaft of bone Similar symptoms to MTSS and compartment syndrome
ST:
Percussion and bump
Tuning fork
Tx: X-ray won't show until healing has begun (3 wks) Rest-14 days Crutch or cast or boot WB once pain subsides After 2 weeks pain free patient can begin running again Orthotics Antiinflammatory Mesa
Achilles’ tendinitis
Inflammation of the tendon
Poorly vascularized-paratenon (vascularized structure that surrounds it)
Older and male more likely
Tenosynovitis causes fibrosis and scarring that can restrict the Achilles’ tendons motions within the tendon sheath
Osis-no inflammation, lost normal appearance, tendon overloaded because of excessive tensile stress from repetitive movements, degeneration of the tendons substance, micro tearing and necrotic areas, as a result of decreased blood flow
MOI: tibial Varum, calcaneal Valgum, hyper pronation, tightness of triceps surae and hamstrings, running mechanisms, increase in activity, type of shoe, surface, weak PF, increased DF or direct blow
S/S:
Soreness and stiffness that comes on gradually and continues to worsen until treated
Decreased gastroc and soleus complex flexibility and tightness
Generalized pain and stiffness about the Achilles
Uphill running or hill workouts make worse
Toe raises deficient
May present at beginning but go away with activity
Morning stiffness and discomfort when walking periods of prolonged sitting
Warm and painful to palpation, as well as thickened
Crepitus
Pain and burning radiating along the length of the tendon
Pt tender at inflamed site
Tx: Proper shoe wear and orthotics Flexibility exercises Ice, ultrasound, cross friction massage Strengthening of the gastroc-soleus Anti inflammatory Heel lifts Immobilization Cortisone injection-increased risk of rupture
Achilles’ tendon rupture
Forceful sudden contraction- stop and go action, pushing off action with knee completely extended
Most prominent in men over 30 and sedentary
Feeling of being kicked-audible pop
Running mechanics, training duration and intensity, type of shoe, running surface, biomechanics, hx of tendinitis, and deconditioning
Direct blow
Chronic inflammation and gradual degeneration
commonly at avascular zone (distal 2-6 cm)
S/S: sudden snap that felt like something kicked him or her in the lower leg Pain is immediate but rapidly subsides Pt tender, swelling, and discoloration Toe raising impossible Obvious indentation at the tendon site Unable to push off or heel raise Stiff leg gait-ER of extremity Defect may be felt with palpation PF still possible through peroneals, flexors, and post tib but contraction is diminished
ST:
Thompson test
Tx: Conservative-casting minimum 8 wks RICE, NSAIDS, analgesics, NWB-6 wks, walking boot for 2 wks DF night splints Rehab for 6 months-ROM Heel lift in both shoes Surgically
Subluxing peroneal tendon
Tear of superior peroneal retinaculum
Forceful sudden DF, eve, PF, and inv
Can be caused by a significant lateral ankle sprain-constant pain behind lateral malleolus
PF muscles become DF
Starts proximally and works distally
Flattened or convex fibular groove, pes planus, rear door valgus, recurrent ankle sprains, laxity of retinaculums
Common in older
Os peroneum-pain and dysfunction, fx, tear of tendon, increased lateral pain during single stance heel rise, inversion ST, and resisted PF
S/S:
Palpable subluxation with active PF and DF or eversion
Pain and dysfunction
Tear of tendon
Lateral instability with pain on post malleolus
Tx:
Surgery
Conservation-rehab, taping, felt pad over peroneal groove
Traumatic anterior compartment syndrome
Blow to ant lower leg
Edema and bleeding causes pressure that obstructs neurovascular network
Medical emergency
S/S:
Pain, pallor, pulselessness, paresthesia, paralysis
Pain w/ passive stretching
Numbness in web space of 1st-2nd toes and dorsal and lateral aspects of foot
Sensory changes not noticed until 1 hour-after 8 hours irreversible changes
Pain with activity, passive and resisted movement, decreased strength with DF
Drop foot gait
Tx:
Surgery
rehab to restore ROM and strength to LE
Profess to functional activities and RTP
Chronic and acute exertional compartment syndrome
Occurs secondary to anatomic abnormalities
Increased thickness of fascia that inhibits venous outflow but not arterial inflow
No prior symptoms or history of traumatic injury
MOI: herniation of muscle, failing fascia to increase, excessive hypertrophy, increased capillary permeability, postexercise fluid retention, decreased venous return, tibia fx, wearing high heels, knee braces, anticoagulants, and diabetes, low diastolic pressure
S/S:
Falling asleep
Once exercise stops s/s go away
Pain, pallor, pulselessness, paresthesia, paralysis
Pain w/ passive stretching
No injury
Numbness in web space of 1st-2nd toes and dorsal and lateral aspects of foot
Sensory changes not noticed until 1 hour-after 8 hours irreversible changes
Pain with activity, passive and resisted movement, decreased strength with DF
Drop foot gait
Tx: Confirm by checking pressure over 30 mm Hg Surgery rehab to restore ROM and strength to LE Profess to functional activities and RTP
Os trigonum
Bony outgrowth from posterior talus-Stedia’s process
First appears between the ages of 8-13 and fuses within 1 year of appearance
Traumatic when SP Fx or stress fx due to stress-forceful and excessive PF
S/S:
Talar compression: Inflammation Of posterior joint, ligaments surrounding the OT, fx of OT, pathology of SP
Painful PF, inversion, and pronation
Symptomatic after activity, repetitive microtrauma, or other inflammatory conditions
Fx: sudden onset of pain after forced PF or DF, swelling lateral or medial to Achilles, pt tender anterior to Achilles and posterior to talus, Painful PF
Tx:

Orthotic or heel cup
Surgical removal of OT
Deep vein thrombophlebitis
Inflammation of veins associated with blood clots

Possible swelling
Warmth, tightness of musculature
ST:
Homans sign-DF and hold, squeeze belly of calf and look for pain, knee is flexed
Tx:
Ultrasound to confirm
Ankle fx/dislocation
Forceful abduction, PF, IR, avulsion fx
inversion, eversion, or rotation:fib or malleolus
Calcaneal and talus fx will present as ankle sprain
Hugier or high dupuytren fx: fibular shaft-may still be able to walk
S/S: Swelling and pain Some or no deformity Snapping or crack noise Pain at site and can radiate Crepitus or discontunity with palpation Ecchymosis
