2) Where are they found?
1) 4 Secondary centers
2) Greater trochanter,lesser trochanter, and the distal end( condyles and epicondyles)
At what age does the femur complete ossification?
15 in females
17 1/2 for males
At what age does the pelvic bone complete ossification?
Anywhere between 20-22
The way the neck of the femur meets the shaft of the bone is called what?
Angle of Inclanation
What is the angle of inclination at its greatest?
At birth (about 145 degrees)
At what stage is the angle of inclination at its smallest
Adult stage at 125 degrees
What is coax valga?
Increase in angle of inclination
Occurs with developmental dysplasia of the hip
What is coxa vara?
Decrease in angle of inclination
Occurs from fractures at proximal part of the femur and the condition of rickets
This fracture people refer to as a broken hip
Subcaptial fracture
What fracture interrupts blood supply to the femoral head that leads to avascular necrosis?
Subcapital Fracture
What arteries supply the neck of the femur with blood?
Medial and lateral circumflex arteries
What are the main functions of the patella?
Additional leverage and power in extension of leg
1) How many ossification centers of the patella?
2) When is it completely ossified?
1) 1 center
2) 10 in females; 13 in Males
Direct trauma to the patella is usually what type of fracture?
Comminuted fracture
Indirect trauma to the patella is usually what type of fracture?
Transverse fracture
Caused by the quadriceps contracting suddenly
Superior lateral portion of the patella remaining unossified is called what?
Patella Emarginata
When the superior lateral portion of the patella ossifies independently is called?
Bipartite or Tripartite Patella
This never fractured!
Softening and fissuring of articulate cartilage on posterior side of patella is called?
Chondromalcia
Pain intensifies with flx to the ext. or exercise
A stinging pain at the lateral aspect of the knee and overuse of gluteus Maximus is called?
ITBS
Iliotibial Band syndrome
What is the large depression on the lateral aspect of each innominate bone called
Acetabulum
What is the largest portion of the pelvic bone called
Ilium
The internal or medial surface of th ilium is called?
Iliac fossa
What marks the boundary between the false pelvis from the true pelvis
Arcuate line
This pelvis is bounded posteriorly ny the lumbar vertebrae
False or major Pelvis
The pelvis is laterally bound to the ilium and anteriorly by the abdominal wall
False or major Pelvis
This pelvis helps support and protect much of the abdominal viscera
False or major Pelvis
This pelvis is bound posteriorly by the sacrum and coccyx
True or minor Pelvis
The pelvis is laterally and anteriorly bound by the ilium, ischium and the pubis
True or minor pelvis
This portion of the pelvis surrounds the birth canal in females.
True or minor pelvis
What are the 4 functions of the pelvic bone
1) Protect the pelvic viscera
2) Transmit body weight to Limbs and absorb the stresses of muscular activity
3) locomotion
4) Provides bony support for birth canal
Where on the femur contains a large number of blood vessels
The neck
