What happens to the blood supply to the head of the femus when the hip is fractured?
interruption in blood supply leads to ischemic necrosis (why hips are often replaced) due to interruption of the medial femoral circumflex artery

the linea aspera
What inserts on the linea aspera?
many different muscles and the three intermuscular septa

From the lesser trochanter to the medial lip of the linea aspera
what runs from the lesser trochanter to the linea aspera?
pectineal line
A small prominence at the uppermost part of the medial femoral condyle
adductor tubercle
What inserts at the adductor tubercle?
The adductor magnus
What tendons insert in the malleolar groove of the medial malleolus of the tibia?
tibialis posterior
flexor digitorum longus
Bumper fracture
Where is it?
What is commonly damaged?
Fracture of the lateral tibial condyle, caused by an automobile bumper.
Usually associated with a COMMON FIBULAR NERVE injury.
This bone has a sulcus for the attachment of the fibularis longus and brevis muscle tendons.
Pott's Fracture
Where is it?
What is damaged?
What force causes this?
Fracture of the lower end of the fibula.
Often accompanied by fracture of the medial malleolus or rupture of the deltoid ligament.
It is cause by forced eversion of the foot.
This injury results in paralysis of all muscles in the anterior and lateral compartments of the leg, causing foot drop.
Fracture of the fibular neck
(Due to damage of the COMMON FIBULAR NERVE)
This is the only tarsal bone without muscle attachments.
This bone transmits the weight of the body from the tibia to the foot.
This bone provides an attachment for the Achilles tendon.
This bony outcropping on the medial side of the calcaneus is crucial for maintaining proper talus orientation.
Sustenaculum tali
The sustenaculum tali supports the head of the talus along with what ligament?
Spring ligament
The bottom of the cuboid bone has a groove for the insertion of what tendon?
Fibularis longus
This muscle/tendon has a groove on the calcaneus and uses the sustenaculum tali as a pulley.
Flexor hallucis longus tendon.
This bone is key in forming the medial longitudinal arch of the foot.
This bone is key in forming the lateral longitudinal arch of the foot.
This bone of the foot has prominent medial and lateral sesamoid bones.
First metatarsal
March Fracture
What is it?
What causes it?
Fatigue fracture of one of the metatarsals.
Can result from prolonged running or walking because of the pull on the metatarsals.
What type of joint is the hip?
Multiaxial ball-and-socket synovial joint.
What stabilizes the hip joint?
Acetabular labrum
Fibrous Capsule
Capsular ligaments
This connects the head of the femur with the acetabulum, transmitting blood and vessels.
Ligamentum Teres
Where is the transverse acetabular ligament?
Goes across the bottom of the acetabulum, covering the acetabular notch.
These structures allow the entry of blood vessels into the acetabulum. (closed by?)
Acetabular fossa and notch.
This part of the hip joint is attached anteriorly to the intertrochanteric line of the greater trochanter and posteriorly to the intertrochanteris crest. It encloses part of the head and most of the neck of the femur.
Fibrous capsule
The fibrous capsule is reinforced by
anterior = iliofemoral ligament
posterior = ischiofemoral ligament
inferiorly = pubofemoral ligament
This is an alteration of the angle made by the acis of the femoral neck to the acis of the femoral shaft so that the angle exceeds 135 degrees, and thus the femoral neck becomes straighter.
Coxa valga
This is an alteration of the angle made by the acis of the femoral neck to the axis of the femoral shaft so that the angle is less than 135 degrees and thus the femoral neck becomes more horizontal.
Coxa vara
This is the largest and most important ligament that reinforces the fibrous capsule and is in the shape of an inverted Y.
Iliofemoral ligament.
This ligament of the hip resists hperextension and lateral rotation at the hip joint during standing.
Iliofemoral Ligament.
This ligament of the hip limits extension and medial rotation of the thigh.
Ischiofemoral Ligament.
This ligament of the hip limits extension and abduction of the thigh.
Pubofemoral ligament.
What is the denticulate ligament comprised of?
Pia Mater
What artery supplies blood to the femoral head via the ligamentum teres?
The obturator artery.
What type of joint is the knee?
Condylar synovial joint.
What motion results in tearing of the ACL?
forward displacement of the tibia
This ligament prevents backward slippage of the tibia on the femur.
Posterior Cruciate Ligament
This knee ligament is taught during extension and lax during flexion of the knee.
Posterior Cruciate Ligament
The patellar ligament is a continuation of what other structure?
Quadriceps Femoris Tendon
What follows along with rootlets?
Blood supply
The deltoid (medial) ligament is where? (And attaches what?)
Medial side of ankle. 4 parts running from medial malleolus to navicular bone, calcaneous, and talus (anterior and posterior).
The lateral side of the ankle is protected by what three ligaments?
1. Calcaneofibular Ligament
2. Anterior Talofibular Ligament
3. Posterior Talofibular Ligament
Type I Ankle Sprain involves what ligament?
Anterior Talofibular Ligament
Type II Ankle Sprain involves what ligaments?
Anterior Talofibular Ligament and Calcaneofibular Ligament
Type III ankle sprain involves what ligaments?
Anterior Talofibular
Posterior Talofibular
Why is an eversion injury more likely to induce fracture of the medial malleolus than tear a ligament?
The medial malleolus is very strongly attached to the deltoid ligament so the ligament will pull of a chunk of bone before it breaks.
What is the cutaneous nerve innervating the front of the thigh and the inside of the lower thigh and leg?
Femoral Cutaneous Nerves.
What is the cutaneous nerve innervating the inner thigh?
Obturator Cutaneous Nerves
What is the cutaneous nerve innervating the lateral lower leg?
Fibural Cutaneous Nerves
Why do varicose veins develop in the superficial veins of the lower limb?
Because of reduced elasticity and poorly functioning valves
This portion of the tibia serves as a point of attachment for the medial meniscus.
