Ankle notes

QuestionAnswer
What are the 5 functions of the foot? support base that provides stability for upright posture w/ min muscle effort, mechanism for rotation of the tibia and fibula during the stance phase, flexibility to adapt to uneven terrain, flexibility for shock absorption, lever during push off
What are the joints of the hindfoot? Tibiofibular, Talocural, Subtalar
Tibiofibular Joint Resting position? Plantar flexion
Tib fib closed packed position Max dorsiflexion
Tib Fib capsular pattern Pain on stress
Which hindfoot joints causes the most problems Talocrural and Subtalar joint
What type of joint is the Talocrural modified hinge
Talocrural resting position 10 deg plantarflexion
Talocrural closed packed position Maximum dorsiflexion
Talocrural capsular pattern Plantar flexion, dorsiflexion
talocrural if musclular what would be limited Dorsiflexion>plantarflexion
Subtalar joint degrees of freedom 3
Subtalar joints what happens when you supinate the foot PF, inversion, adduction
Subtalar joints what happens when you pronate the foot DF, eversion, abduction
Subtalar Resting position Midway between extremes
Subtalar closed packed position Supination so it is firm for push off in gait
Subtalar Capsular pattern Varus, valgus (5 deg or both)
Midfoot 5 joint what are they? Talocalcaneonavicular, cuneonavicular, cuboidenavicular, cuneocuboid, calcaneocuboid
Midfoot Resting position between extremes of range of motion
Midfoot closed pack supination
Midfoot Capsular pattern DF, PF, add, medial rotation
Forefoot joints? Tarsometatarsal, Intermetatarsal, Metatarsophalangeal, Interphalangeal
Mechanism of injury chronic vs acute Chronic - runner tendinosis Acute = inv & PF, ev & DF
Runners questions? shoes, miles/week, terrain, hills, pace, how often, when does it start hurting, what time of day, have they changed mileage, where do they run on the road
Observation Weight Bearing Anterior view Supination (pes cavus) or pronation (pes planus)
Observation weight bearing posterior pes planus, cavus, pump bump (swelling where achilles tendon attaches
Observation WB lateral view medial arch, lateral arch, transverse arch
Non weight bearing Valgus vs varus rear foor to forefoot, Plantar flexed first ray (in all 2-5th in one plane and 1st is PFmore than the rest), Heel cord tightness(foot more PT limited DF)
Talipues equinus? Limited dorsiflexion, contracture of gastroc and soleus
Club foot Congenital deformity, also called talipes equinovarus
Hindfoot varus inversion of the calcaneus when subtalar joint in neutral
Morton's Metatarsalgia interdigital neuroma that forms between 3 and 4th web space
Exostosis (bony spur) attached to ligaments, fascia, tendons
Bunionette (tailor's Bunion) similar to bunion with hallus valgus but on the 5th metatarsal
Turf toe Hyperextension injury
Morton's foot second toe longer than first
First MP joint is commonly affect by what? Gout and bunions
Navicular bone articulates with 5 other bones what are they? talar head, 3 cuneiforms and the cuboid
the sustentaculum Tali and why is it clinically important? what will occur if there is problems with its anatomical alignment Clinically itsupports the talus and serves as an attachment of the spring ligament it out of alignment will lead to flat feet (pes planus)
Medial tubercle of the talus is an insertion point for what? Medial collateral ligament
the sinus tarsi is filled with what muscle? extensor digitorum brevis
what attaches to the styloid process of 5 metatarsal? peroneus brevis
What is a tailer's bunion? occurs when swelling, redness and tenderness occurs over the styloid process of the 5th
what runs through the cuboid groove Peroneus longus
Medial calcaneal tubercle is an attachment sight for what? what commonly happens here? Abductor hallucis muscle and the plantar aponeurosis, commonly a location for heel spurs
What part of the calcaneus is weight bearing the medial calcaneal tubercle NOT the lateral calcaneal tubercle
What provides the main blood supply to the foot? Posterior tibial artery
which ligament on the lateral side of the ankle is the stongest? Posterior talofibular ligament
