Quiz 6 Flashcards
Hindfoot
calcaneus & talus
Midfoot
cuboid, navicular & cuneiform
Forefoot
metatarsals & phalanges
Considerable differences in thickness
Foot
Foot consists of how many bones
26
Foot is divided into three parts:
- 14 phalanges (Cones of the toes)
- 5 metatarsals (bones of the instep)
- 7 tarsals (bones of the ankle)
MTP joints classified as
ellipsoidal-type joints
IP joints are ___, ______ type
synovial, diarthrodial hinge
bone of the heel
calcaneus
ankle bone
Talus
Seven tarsal bones of the ankle
Calcaneus
Talus
Navicular
Cuboid
Medial cuneiform
Intermediate cuneiform
Lateral cuneiform
Largest and strongest tarsal bone
Calcaneus
-Also known as os calcis
-Usually examined separate from the ot, if injured
Calcaneus
- is located on the osterior and inferior portions
- Attachment of the Achilles tendon
Tuberosity
Usually examined separate from the foot, if injured
Calcaneus
Three articular facets joint with the talus
- Anterior facet
- Middle facet
- Posterior facet
- Is a groove located between the middle and posterior talar articular facets
Calcaneal sulcus
- Located on medial aspect and extends outward as a shelf-like overhang
Sustentaculum tali
- Located on the lateral surface
Trochlea
Occupies the highest position of the foot
talus
Second largest tarsal
Talus
Talus Articulates with 4 bones:
-Calcaneus at the “subtalar” joint
- Navicular
- Tibia
- Fibula
On lateral side between calcaneus and the fourth and fifth metatarsals
Cuboid
On medial side between talus and the three cuneiforms
NAVICULAR
Occupy the central and medial aspect of the foot between the navicular and the first, second, and third metatarsals
Cuneiforms
The ankle joint is formed by articulatio etween the talus tarsal and the:
- Lateral malleolus of fibula
- Inferior surface of tibia
- Medial malleolus of tibia
The ankle joint is classified as a_____ allows flexion and extension
synovial, hinge-type joint
The slight adduction/abduction and rotation motions of the ankle result from _____ rather than the ankle oint proper.
the intertarsals’ gliding novements
- Talipes equinovarus
- Abnormal twisting of the foot usually inward & downward
Congenital Clubfoot
- Avulsion fx of the medial malleolus with loss of the ankle mortise
Pott’s Fx
- Avulsion fx of the base of the fifth metatarsal
Jones Fx
- Lucent lesion in the metaphysic usually at the distal femur
Osteoclastoma
- Incomplete separation or avulsion of the tibial tuberosity
Osgood-Schlatter Disease
- Osteoclastoma
- Lucent lesion in the metaphysic usually
Giant Cell Tumor
- Runner’s knee
- Softening of the cartilage under the patella
Chondromalacia Patellae
- Accumulation of fluid in the joint cavity
Joint Effusion
- Abnormal separation in the base of 1st & 2nd metatarsal & cuneiform
Lisfranc Injury
- Erosions of sacroiliac joints & lower limbs
Reiter Syndrome
- Congenital abnormality of hallux
- Lateral deviation of great toe
Hallux Valgus
Projections of the toes
- AP/AP AXIAL Projection
- PA Projection
- AP Oblique Projection - Medial/Lateral Rotation
- PA Oblique Projection - Medial Rotation
- Lateral Projections
- Mediolateral
- Lateromedial
