EXAMINATION OF THE FOOT AND ANKLE Dr. Mohammed Zaheer Dalati Senior Registrar Department of Orthopaedics College of Medicine King Khalid University Hospital
Objectives Review anatomy of Foot and Ankle. Discuss key history Hands on exam Discuss cases concerning common injuries of the Foot and Ankle
Anatomy
History Onset Duration Mechanism Swelling / Ecchymosis Ambulation Hx of previous injury
2 PARTS: 1- ERECT POSITION. 2-SUPINE POSITION.
Inspection. Palpation. Movements. Special tests.
INSPECTION OF THE PATIENT’S GAIT: Evaluation of the walking cycle GAIT ANALYSIS
STANCE PHASE 65% –Contact Period - heel strike to forefoot loading –Midstance Period - forefoot loading to heel raise –Propulsive Period - heel raise to toe off SWING PHASE 35%
GAIT ANALYSIS Stance phase
Trendelenburg gait
Tip-toe walking
Foot drop walking
Spastic gait
Intoeing/Out toeng gait
Antalgic gait
Inspection in standing position
INSPECTION: POSTERIOR HEEL STANDING
FOOT SHAPE
ALL THE TOES SHOULD BE IN GROUND CONTACT IN W.B.(stability of the foot on the ground)
INSPECTION: of the L.L Any asymmetry of length, rotational problem, or mal alignment of the lower limbs.
INSPECTION: - Deformity, swelling, skin changes, muscle wasting, asymmetry of length, abnormal position…. INSPECT ALL ARROUND
INSPECTION: PLANTAR SKIN callosity
Palpation: Bone and joints Soft tissues
Anatomical landmarks: -Medial malleolus, lateral malleolus, Achilles tendon, calcaneal tuberosity, peroneal tendon, tibialis posterior tendon, tibialis anterior tendon, plantar fascia, base of 5th metatarsal, 1st MP joint, metatarsal heads……..etc
PALPATION: Tenderness, swelling, deformity…. Knowing the anatomy:
MOVEMENTS: Ankle: -dorsiflection -plantar flection. Subtalar: -inversion -eversion. Midtarsal: -pronation -supination Tarso-metatarsals: move the metatarsals one by one. Toes:
Ankle movements:
MOVEMENT: SUBTALAR: MOVE THE HEEL: Inversion---eversion
Midtarsal supination Move the metatarsals one by one
MOVEMENTS: IMPORTANCE OF THE BIG TOE (running, jumping) Problem of hallux rigidus
EXAMINATION OF THE SHOES
Special tests
Ankle sprain: Lateral ligament. Stress view. Anterior drawer. Varus stress test. Dynamic X-Ray
SPECIAL PATHOLOGIES: Ligaments injuries: -Lateral collateral ligament of the ankle: varus stress view AP. -Subtalar ligaments: increased valgus by standing on one leg.
ACHILLES TENDON: -RUPTURE:(signs in prone position) ~depression. ~absence of rest plantar flexion. ~no plantar flection by squeezing the calf muscles.
SPECIAL PATHOLOGIES Pes planus: common 20% -GAIT: UGLY. -INSPECTION STANDING: HEEL, ARCH, FOREFOOT. -LIGAMENT LAXITY -MOVE THE HEEL AND THE 1 ST METATARSAL. -EXAMIN THE TENDO ACHILLES -May be asymptomatic
Pes cavus High arch Varus
Special pathologies: TARSAL COALSION: Painful stiff flat foot Usually bilateral, can be unilateral -Stiff subtalar. MORE COMMON:calcaneo- navicular and subtalar. -Request CT scan
SPECIAL PATHOLOGIES: INTOING GAIT: -Internal femoral torsion: exaggerated anteversion. -Internal tibial torsion. -Forefoot adduction.
SPECIAL PATHOLOGIES: -PLANTAR FASCIITIS: ~Any tightness of Achilles tendon. ~Any mechanical foot disorder. ~Any use of bad shoes.
Metatarsalgia
Hallux valgus
Hallux rigidus: O.A 1 st MPJ
