Introduction[edit | edit source]
Osteology pelvic limb[edit | edit source]
The Pelvic limb bears 40-45% of the weight and provides the majority of the propulsion for locomotion.
Os coxae[edit | edit source]
- Tuber coxae end tubes sacrale both palpable
- Tuber ischii underneath hamstrings
Femur[edit | edit source]
- Greater trochanter lateral to the head of the humerus
- Lesser trochanter distal to head of humerus
- Trochanteric fossa: Caudal depression between the trochanters
- Third trochanter: Lateral aspect distal to greater trochanter
- Extensor fossa. depression on lat condyle for insertion of long digital
extensor.
Femoral trochlea: Groove on cran femur for articulating with patella bound by two ridges of which the medial is thicker.
Patella[edit | edit source]
Fabellae[edit | edit source]
- Two small sesamoid bones embedded in the heads of the gastrocnemius muscle
Tibia[edit | edit source]
- Large tibial tuberosity - patellar ligament
- Cochlea = two grooves seperated by a ridge
Fibula[edit | edit source]
- Does not bear much weight
Tarsals and metatarsals[edit | edit source]
- Dogs and cats have 7 tarsal bones
- Reduced first MT and digit (dew claw) often absent
Joints of the pelvic limb[edit | edit source]
Sacro-iliac[edit | edit source]
Type:
- Synchondrosis ( synovial joint - sacropelvic surface of illium
- Joint capsule present
ROM:
- Minimal. Designed for stability
- Accessory movements = rot
Supporting structures:
- Dorsal and ventral Sacroiliac ligaments
- Sacrotuberous
Hip[edit | edit source]
Type:
- Ball and socket
- Femoral head and acetabulum of the illium, ischium and pubis
- A band of fibrocartilage on the rim of the acetabulum deepens acetabtilum
ROM:
- FL & Ext
- Minimal - add & abd
Supporting structures:
Acetabular lip (fibrocartilage) continues as transverse ligament
Ligament of the femoral head
Synovial structures and tendon sheaths:
- Large joint capsule
- Internal obturator
