Psoas Sign
|
One of the tests used to determine if a patient has appendicits. Dr places hands on thigh superior to knee and asks patient to flex hip. Pain results.
|
|
Adductor Longus, Adductor Brevis, Adductor Magnus (add portion)
|
Adduction and hip flex. Obturator Nerve. L2-L4.
|
|
Adductor Magnus (ham)
|
Extension of hip. Tibial portion of sciatic nerve L4.
|
|
Gracilis
|
Adduction of hip and flexion of leg. Obturator nerve. L2-L4
|
|
Obturator Externus.
|
Lateral rotator of thigh. Obturator nerve L2, L3, L4

|
Extension of Hip, Tibial portion of sciatic nerve. L5, S1, S2
|
|
Semitendinosus. Semimembranosus
|
Hip Extensor. Tibial portion of sciatic nerve. L5, S1, S2
|
|
Unhappy Triad.
|
MCL is most commonly torn. Posterolateral force on extended planted knee. MCL and ACL to rupture. It also tears the medial meniscus.
|
|
Intermittent cluadication
|
Atherosclerosis blocks femoral artery. Causes ischemia in muscles it supplies during exercise. Pain goes away after resting. Area of pain indicates where blockage is.
|
|
Avascular necrosis
|
Condition when bone and marrow break down due to poor blood supply. If this occurs near a joint it results in collapse of joint surface causing pain and impaired mobility. MRI diagnose. The hip is the most common place of AVN.
|
|
Sciatic Nerve
|
Largest nerve in the body forms from the Ventral Rami of L4-S3. The tibial nerve is anterior portion and the fibular nerve is posterior.
|
|
Tibial Nerve
|
L4-S3. Anterior division. Biceps femoris long head. Semimembranosus and semitendinosus. Gastroc, soleus, plantaris, Posterior Tibial, Flexor Hallucis Longus, Flexor Digitorum Longus,
|
|
Fibular Nerve
|
L4-S2. Posterior division of ventral rami. Biceps short head. S2 is in the foot only. Divides into Superficial (flexor longus and Brevis L5-S2 Lateral) and deep (L4-S1)
|
|
Obturator Nerve (L2-L4) Anterior Injuries
|
Rare. Pressure from trauma, difficult delivery, hysterectomy, obturator hernia, carcinoma of cervix, bladder, rectur. Difficulty walking. Abducts thigh and bad medial rotation. Pain or decreased sensation to medial portion of the thigh.
|
|
Branches of femoral artery
|
In the femoral triangle, the femoral artery gives off numerous small cutaneous branches, that suppy the upper thigh and perineum. The superficial epigastric, superficial circumflex illiac artery, superficial external pudendal artery, deep external pudendal. First perforating branch off the deep femoral participates in cruciate anastomosis.
|
|
Crural fascia
|
Dense, unyielding, exoskeleton. Origin for muscle, forms two septae (anterior and posterior intermuscular septae that attach to the fibula. Along with the interosseus membrane it forms the compartments of the leg.
|
|
Retinacula in ankle
|
Crural fascia forms thickens to form 2 retinacula that maintain muscles in proper position to mmaximize efficiency. Superior extensor retinacula and inferior Y shaped retinacula.
|
|
S1 Dermatome
|
It gives cutaneous innervation to lateral heel and foot via the calcaneal branches of the sural nerve.
|
|
Fibularis longus and brevis
|
Eversion and plantarflexion. Superficial Fibular L5-S1-S2. posterior ventral rami. Lateral compartment muscles.
|
|
Popliteal fossa.
|
Transition between thigh and foot/leg. Neurovascular supply found here. Diamond shapped 3 muscles form border.
1. Biceps femoris (superolateral) 2. Semitendinosus/semimembranosus (Superomedial) 3. 2 heads of the gastrocnemius inferior. |
