Chapter 4Clinical Assessment of

Foot & Toe Injuries

Part II

Student Learning Outcomes

Identify common midfoot & forefoot injuries based on their presenting history, symptoms, visual signs (inspection), & palpation findings

Identify special tests that might be used to evaluate these injuries

Discuss basic management strategies for dealing with these injuries

Discuss anatomical or biomechanical predisposing factors associated with these common midfoot & forefoot injuries

Location of Pain: Medial Calcaneus/Medial Arch

Injuries to consider (continued from Ch. 4 Part 1)

tarsal tunnel syndrome impingement &

inflammation of the posterior tibial nerve within the tarsal tunnel

History

Tarsal tunnel syndrome Symptoms

pain, numbness, or parasthesia along medial or plantar aspectof foot

may mimic plantarfasciitis

Onset Acute or chronic

History

Tarsal tunnel syndrome MOI

EV or PF/EV ankle injury (acute)

Forced PF (acute) Repetitive stress

associated with pesplanus foot

Previous history of tarsal fx

History

Tarsal tunnel syndrome Possible related factors

Training surface Distance Shoes

Inspection

Tarsal tunnel syndrome pes planus foot typically no swelling,

discoloration, or deformity

Palpation

Tarsal tunnel syndrome Point tenderness

proximal, over, and distal to the flexorretinaculum

ROM

Tarsal tunnel syndrome AROM

normal EV may reproduce

symptoms PROM

PF & EV may reproducesymptoms

RROM may demonstrate

weakness of toe flexors

Stress Tests/Special Tests

Tarsal Tunnel Syndrome n/a

Neurological Tests

Tarsal Tunnel Syndrome Tinel’s sign Decreased sensation

over nerve distribution

Management

Tarsal Tunnel Syndrome Ice NSAIDs Orthotics Surgical release (in

severe cases)

insertion sites tarsal coalition


Injuries to consider fx/dislocation

Lisfranc injury navicular stress fx

Lisfranc injury


Injuries to consider: sprain

Injuries to consider: strain/inflammation of muscle/tendon at

insertion sites tibialis posterior tibialis anterior peroneal longus peroneal brevis


Injuries to consider: Tarsal coalition

abnormal union between two or more tarsals bony fibrous Cartilaginous



typically presents between 3 – 16 yrs of age 3 – 5 yrs: talonavicular coalition jt. 8 – 12 yrs: calcaneonavicular jt. 12 – 16 yrs: talocalcaneal jt.

History

Location of pain

(midfoot)Symptoms Onset MOI

Fx/dislocationAcute; trauma

Dropping something on the foot; stepping in hole or on uneven ground - twisting the foot

Lisfranc fx**Acute; trauma

Dropping something on the foot; stepping in hole or on uneven ground - twisting the foot**

SprainAcute; trauma

Twisting the foot

Strain/inflammation of tendon insertion site(s)

Acute or chronic

Forceful contraction; repetitive stress

Tarsal coalition congenital n/a

Location of Pain: Forefoot

Injuries to consider Fx

midshaft avulsion Jones’ fx

Intermetatarsal (Morton’s)neuroma

metatarsalgia

History

Location of pain

(forefoot) Symptoms Onset MOI

Midshaft fxPain directly over

metatarsal

Acute or chronic

(stress fx)

Acute: Getting stepped on or having something dropped onto MT; stepping in hole or onto uneven surface;

Chronic: repetitive stress, weakness of toe flexors

Avulsion fx

Most common site: styloid process of 5th MT

Pain over fracture site; may have heard/felt pop

AcuteBase of 5th MT: forceful contraction of peroneal

brevis

Jones’ fxPain over distal styloid of

5th metatarsalAcute

Force inversion with ankle in PF; landing on lateral

aspect of foot

Morton’s neuroma Pain, burning

Metatarsalgia Pain under head(s) of

metatarsals; may feel like “stepping on pebble”
