    Study Notes

    Pelvic Limb Joints

    • Joints of the pelvic limb: sacroiliac joint, coxofemoral (hip) joint, stifle joint, tarsus, proximal and distal interphalangeal joints, and metatarsophalangeal joints.

    Coxofemoral Joint

    • Formed by the ilium, ischium, and pubis bones.
    • The head of the femur (ball) articulates with the acetabulum (socket) of the pelvis.
    • Primary movements: flexion and extension.
    • Also allows for abduction, adduction, and circumduction.

    Stifle Joint

    • Formed by the femur, patella, tibia, and fibula bones.
    • Primary movements: flexion and extension.
    • Consists of three individual joints: femorotibial, femoropatellar, and proximal tibiofibular joints.

    Ligaments and Structures of the Stifle Joint

    • Patellar ligament: connects the patella to the tibial tuberosity.
    • Collateral ligaments: located on the lateral and medial sides of the stifle, extra-articular, and help stabilize the stifle.
    • Lateral collateral ligament: courses from the femur to the fibula and tibia, limits medial (varus) motion of the tibia.
    • Medial collateral ligament: courses from the femur to the tibia, limits lateral (valgus) motion of the tibia.
    • Cruciate ligaments: intra-articular, course between the femur and tibia.
    • Cranial cruciate ligament: attaches to the tibia cranially, prevents the tibia from sliding cranially.
    • Caudal cruciate ligament: attaches to the tibia caudally, prevents caudal movement of the tibia.

    Muscles of the Pelvic Limb

    • Quadriceps femoris muscle: 4 heads, originates from the pelvis (ilium – cranial to the acetabulum) and proximal femur, inserts into the tibial tuberosity, actions: flex the hip, extend the stifle.
    • Semitendinosus muscle: originates from the pelvis (tuber ischii), inserts into the proximal, caudal tibia and calcaneus, actions: extend the hip, flex the stifle, extend the hock calcaneus.
    • Tuber ischii: a hamstring muscle, originates from the pelvis (tuber ischii), inserts into the proximal, caudal tibia and calcaneus, actions: extend the hip, flex the stifle, extend the hock calcaneus.
