Study Notes
Bones of the Lower Limb
-
The lower limb (extremity) is specialized for supporting body weight, locomotion (moving from one place to another), and maintaining balance.
-
Bones of the lower limb include those of the hip bone (os coxae), forming the pelvic girdle, which also comprises the skeleton of the trunk.
-
The hip bone is formed by the fusion of three primary bones: ilium, ischium, and pubis. This fusion occurs between ages 20 and 25.
-
Bones of the free lower limb include the femur (thigh bone), patella (knee cap), tibia (shin bone), and fibula (calf bone).
-
The foot includes the tarsus (connecting the ankle and foot), metatarsus, and phalanges (toe bones).
-
The acetabulum is a cup-like cavity on the hip bone's lateral aspect, articulating with the femur's head.
-
The acetabular notch is crossed by a transverse acetabular ligament, contributing to joint stability and forming a part of the load-bearing surface for the femoral head.
-
The obturator foramen is a bony opening bordered by the ischium and pubis. An obturator membrane closes this opening near the superior part of the foramen and provides surface area for muscle attachment.
-
The iliac crest, a superior border of the ala, the hip bone's wing-like portion, serves as a point of attachment for ligaments. The anterior surface of the ilium, called iliac fossa, forms a depression. The gluteal surface, ilium's posterior external surface, directs toward the gluteal region. The sacropelvic surface, which faces the sacrum, has an auricular surface (ear-shaped articular area for sacrum), and an iliac tuberosity (rougher area superior to the auricular surface).
-
The ilium has four iliac spines (anterior superior iliac spine, anterior inferior iliac spine, posterior superior iliac spine, and posterior inferior iliac spine) for ligament and tendon attachments.
-
The ischium forms the lower and posterior part of the hip bone. It includes a body(corpus), a ramus, and the ischial spine and tuberosity (tuber).
-
The pubis forms the anterior portion of the hip bone. It includes a body, superior ramus, inferior ramus, pubic tubercle, and pubic crest.
-
The obturator foramen is enclosed by the superior ramus and inferior ramus of the pubis and the inferior ramus of the ischium.
-
Bones within the lower leg include the tibia and fibula. The tibia is positioned in the anteromedial region of the leg, while the fibula lies laterally. The shafts of the tibia and fibula are joined by the interosseous membrane.
-
The talus articulates with the tibia and fibula of the ankle (superior surface), the calcaneus and navicular (inferior surface), and the cuneiforms. The calcaneus is the largest tarsal bone, which supports the talus and forms the heel. It possesses sustentaculum tali for talus support. There is a calcaneal sulcus on the inferior surface of the talus.
-
The parts of the foot including cuneiform bones, cuboid, metatarsals, and phalanges.
-
The metatarsals have a tuberosity on the first and fifth.
-
The bones are firmly connected in the syndesmosis.
Additional Information
- Terminology like "AP radiograph", "lateral radiograph," "mortise," and "growth plates" are mentioned in the context of imaging analysis and anatomical features.
- Descriptions of fractures and their classifications (e.g., Garden classification) in relation to surgical treatments (e.g., osteosynthesis) are noted.
