Study Notes

Navicular Bone

The plantar surface of the navicular contains a tuberosity for the attachment of the tibialis posterior tendon.

Metatarsals

Metatarsals are located in the forefoot, numbered I-V from medial to lateral.
Each metatarsal is convex dorsally and consists of a head, neck, shaft, and base.
Tarsometatarsal joints connect metatarsal bases to tarsal bones, while intermetatarsal joints connect adjacent metatarsals.
Metatarsophalangeal joints are formed between the metatarsal head and proximal phalanx.

Cuneiform and Cuboid Bones

The distal row consists of four tarsal bones: cuboid and three cuneiforms (lateral, intermediate, medial).
Cuneiforms articulate with the navicular posteriorly and metatarsals anteriorly, aiding in forming a transverse arch.
The cuboid is the most lateral tarsal bone, located anterior to the calcaneus and between the fourth and fifth metatarsals.
Its inferior surface has a groove for the tendon of fibularis longus.

Phalanges

Phalanges are the bones of the toes; the second to fifth toes have proximal, middle, and distal phalanges, while the great toe has only proximal and distal.
Each phalanx consists of a base, shaft, and head, similar in structure to metatarsals.
Phalanges serve as attachment points for several muscles, including tibialis anterior, part of tibialis posterior, and fibularis longus.

Knee Joint Bursa

Deep bursa lies between the tibia and patellar ligament.
Superficial bursa lies between patellar ligament and skin.
Semi-membranosus bursa is located behind the knee joint, between semimembranosus muscle and the gastrocnemius.

Knee Joint Menisci and Ligaments

Medial and lateral menisci are fibrocartilaginous structures that stabilize the joint and act as shock absorbers.
The major ligaments include:
- Patellar ligament: extension of the quadriceps femoris tendon.
- Collateral ligaments: stabilize knee motion, preventing excessive medial/lateral movement.

Tibiofibular Joints

Proximal tibiofibular joint is formed by the head of the fibula articulating with the lateral condyle of the tibia.
Distal tibiofibular joint is supported by the interosseous membrane and anterior inferior tibiofibular ligament.

Ankle Joint

The talocrural joint is a synovial joint formed by the tibia, fibula, and foot.
Functions as a hinge joint, allowing dorsiflexion and plantarflexion.

Subtalar Joint

The subtalar joint generates eversion and inversion movements and is formed on an oblique axis.
Eversion is produced by the lateral compartment of the leg, while inversion is primarily by the tibialis anterior muscle.

Movements of the Knee

Flexion is produced by hamstrings, gracilis, sartorius, and popliteus.
Lateral rotation is attributed to the biceps femoris muscle.
Medial rotation is produced by semimembranosus, semitendinosus, gracilis, sartorius, and popliteus.
Medial and lateral rotations occur only when the knee is flexed.
