1

tuber coxae muscle attachments

internal abdominal oblique, superficie gluteal, external abdominal oblique, tensor fascialattate

2

ischiatica tuberosity muscle attachments

semitendinosus, semimembranosus, ischiocavernosus, biceps fem

3

greater trochanter muscle attachments

middle gluteal, deep gluteal, accessory gluteals

4

patella muscle attahcments

quads, flabella (gastroc)

5

poplietus tendon associated with

sesamoid

6

lesser trochanter muscle attachments

iliopsoas

7

3rd trochanter muscle attachments

superficial gluteal

8

extensor fossa muscle attachments

this is on lateral side; common tendon fibularis terminus, long digital extensor

9

femur bony landmarks

lesser trochanter, greater trochanter, 3rd trochanter, medial and lateral condyles, extensor fossa, trochlea

10

femoral condyles

ventral to 3rd trochanter

11

extensor fossa

medial to lateral condyle

12

medial and lateral trochlear ridges

on radiograph of stifle lateral view rounded prominences ventral to patella dorsal to tibia; medial appears more dorsal lateral appears more ventral

13

tibial tuberosity

on lat radiograph seen on medial side digit in cranial part of tibia

14

components of equine hip joint

ligament of the head of the femur, joint capsule, supporting musculature (iliopsoas and gluteal muscles), accessory ligament and transverse acetabular ligmanet

15

what makes up the equine hip joint

articulation of the femoral head with the acetabulum of the pelvis

16

main plane of movement of hip joint

flexion and extension

17

what components does the equine hip joint have that the dog does not

accessory ligament and transverse acetabular ligament

18

accessory ligament

arises from thick prepubic tendon and passes dorsal to transverse acetabular ligament to insert on peripheral part of fovea of the femoral head

19

transverse acetabular ligament

arises from fibrous rim that depends the acetabulum

20

clinical correlate of horse hip

horses tend not to dislocate their hips bc musculature stabilizes it; if they do its v hard to reduce it

21

pelvic limb blood supply main pipline

1. external iliac
2. Femoral
3a. popliteal
4a. cr tibial
5a. dorsal metatarsal

or
3b. Saphenous
4b. Medial and lateral plantar and plantar metatarsal arteries

22

femoral nerve

giant nerve, protected by iliopsoas; innervates iliopsoas and quads, needed for weight bearing

23

saphenous nerve

branch off of femoral nerve; provides autonomous innervation to medial crus (don't really test this in horses unless they are down)

24

obturator nerve

goes through obturator foramen, innervates muscles of adduction
- gracilis
- adductor
- pectineus

25

Sciatic nerve

goes medial -> lateral between greater trochanter and ischiatic tuberosity; branches into common fibular and tibial nerves
innervates cd thigh muscles
- biceps femoris
- semitendinosus
- semimembranosus

26

common fibular nerve

aka common peroneal
- splits into superficial and deep branches; provides sensation down D (cr?) aspect of limb
innervates cr crus muscles

27

tibial nerve

runs down cd aspect of limb;
innervates cd crus muscles

28

cr gluteal nerve

innervates muscles cr to hip jt
- superficial gluteal
- deep gluteal
-middle gluteal
- accessory gluteal

29

cd gluteal nerve

innervate muscles cd to hip jt (cd thigh muscles and superficial gluteal)
- superficial gluteal
- biceps femoris
- semitendinosis
- semimembranosus

30

clinical correlates hip

3rd trochanter avulsion fracture
trochanteric bursitis
