popliteal notch

on the posterior intercondylar area of tibia where the PCL attaches

Gerdy's tubercle

on lateral condyle, anterior aspect of tibia, where IT band attaches

groove for semimembranosus tendon

on medial condyle, posterior aspect of tibia

surfaces + borders of tibia

- anterior, medial, and lateral borders


- medial, posterior, lateral surface


- medial surface has no muscle origins


- anterior border and most medial border are subcutaneous and normally palpable

what muscle tendon runs along the medial malleolar sulcus?

medial malleolar sulcus is on the posterior surface of the tibia and the tibialis posterior tendon runs along it.

primary ossification center of tibia located and when does it appear?

located at diaphysis of tibia and appears at 7-8 weeks in utero

subcutaneous and normally palpable parts of fibula

the head of the fibula, the distal triangular part of anterior border, lateral malleolus

anterior compartment muscles of leg

extensors/dorsiflexors; postaxial; innervated by posterior division of ventral rami

lateral compartment muscles of leg

everters; postaxial; posterior division of ventral rami

posterior compartment muscles of leg

flexors/plantarflexors; preaxial; anterior division of ventral rami

pott's fracture

fracture of fibular diaphysis, medial malleolar avulsion, and tallar displacement - occurs during ankle sprain

osgood-schlatter disease

overuse injury - child is growing but constant tension of quadraceps causes bone to grow

three surfaces that comprise the trochlea

medial malleolar (comma shaped), superior, and lateral malleolar (triangular shaped) ---- the talus

neck of talus (sulcus tali)

sulcus tali and sulcus calcanei form the hollow space. The lateral part of the space is sinus tarsi and medial part of space is the canalis tarsi.

during normal development does medial deviation of the head of the talus increase or decrease?

it decreases

what three main arteries send branches to talus

-fibular/peroneal; anterior tibial; posterior tibial


-anterior tibial artery becomes dorsalis pedis artery

what soft tissue structure attaches to the calcaneal tuberosity?

achilles tendon

what facet is found on the anterior surface of calcaneous?

articular facet for the cuboid

what ligament attaches at the cuboid promontory?

long plantar ligament

what runs along the peroneal notch and sulcus?

fibularis longus

what muscle tendon attaches on the navicular tuberosity?

tibialis posterior

fibers of what ligament attach at the navicular tuberosity?

tibionavicular

three types of calcaneonavicular coalition

- bony elongations of each tarsal united by cartilage, fibrous connection (syndesmosis), bony bar (synostosis)

lateral cuneiform- what muscles sends tendon fibers to the crest

tibialis posterior

what muscle originates in part from the crest of the lateral cuneiform?

flexor hallucis brevis

Synarthrosis

Fibrous joints. Suture = skull; gomphosis = tooth; syndesmosis = inferior tibiofibular

Synarthrosis

Fibrous joints. Suture = skull; gomphosis = tooth; syndesmosis = inferior tibiofibular

Amphiarthrosis

Cartilaginous joints. Primary cartilaginous = synchondrosis. Secondary cartilaginous = symphysis

Synostosis

When full length is achieved, the head and shaft fuse. Part of Amphiarthrosis.

Developmentally dorsal muscles

Move anteriorly. POSTAXIAL. Posterior division of ventral rami. (Femoral)

Superior talofibular joint

Synovial plane joint

Inferior tibiofibular joint

Fibrous syndesmosis

Ankle joint

Compound synovial; modified ginglymus; hinge
