Terms | Definitions |
|---|---|
 Sacroiliac joint | Transmits weight onto the trunk. Provides firmness of attachment and shock absorption |
| Sacroischiatic ligament | Very like aponeurosis |
| Hip joint | Deduced by greater trochanter of femur |
| Stability of hip joint | Due to extent and depth of acetabulum, area of the femur head and accessory ligament |
| Accessory ligament | Also restricts rotation and abduction |
| Stifle joint | Important in locking mechanism of patella, passively support the hindlimb to bear weight. Locking mechanism due to assymmetrical femoral trochlea |
| Trochlear surface | Larger gliding area and smaller resting surface |
| 3 patellar ligaments | MePL, MiPL and LPL Connected by common retinaculum on which aponeurosis of TFL and BF inserts |
| MePL | Extends from parapatellar cartilage to tibial tuberosity and is more widely placed |
| To relieve patella from stifle | Cut MePL as it releases parapatellar cartilage |
| Resting surfaced engaged | During support phase of walking stride and when horse stands with its weight equally distributed |
| Gracilis and sartorius | Insert on MePL |
| TFL and BF | Insert on LPL |
| Medial CL | From medial femoral epicondyle to tibia, landmark to approach med femoro-tibial compartment |
| Lateral CL | From lateral femoral epicondyle to head of fibula, landmark to approach lat femoro-tibial compartment |
| 4 joint cavities | Prox femoropatellar Dist femoropatellar Med femorotibial and lat femorotibial- do not communicate |
| Hock joint | Lat and med collateral ligaments Long plantar ligament |
| Long plantar ligament | Runs under SDF Inserts on MT IV Can be palpated either side of SDF |
| "CURB" | Long plantar ligament can become strained as it is close to SDF, causing inflammation and thickening |
