Clinical Anatomy Flashcards
(126 cards)
What does a bump on a bone (i.e. the tibial tuberosity) signify?
It is a place for a muscle attachment
What parts of the pelvis often fracture in older patients with osteoporosis?
Pubic Ramus
Sacroiliac joints
Name the 3 compartments of the knee
1) Medial
2) Lateral
3) Patello-femoral
What is the ankle mortise and what does it hold in it?
Lateral malleolus (fibula)
Distal Tibia
Medial Malleolus
holds TALUS bone in it
Where is Chopart’s joint located?
Between hindfoot and midfoot
What joints in the foot are responsible for abduction/adduction?
joints between midfoot and forefoot
What is the acetabular labrum?
ring of cartilage that surrounds the acetabulum of the hip
What is the function of the acetabular labrum?
Increases contact with the femoral head in the joint socket
=> joint is more stable
What type of hip fracture is treated by replacement?
Intra-capsular
- due to risk of avascular necrosis
What type of hip fracture is treated by surgery and normal healing?
Extra-capsular
- since blood supply is still intact it should heal relatively well
What muscles are described as the Hip Flexors?
ILIACUS
PSOAS MAJOR
Where does the iliacus muscle attach to?
Origin: Iliac crest / inner aspect of ilium
Insertion: Lesser trochanter of femur
What is the origin and insertion of the psoas major muscle?
Origin: Transverse processes L1-L5
Insertion: Lesser trochanter
In what patients does a psoas abscess usually present?
Immunocompromised
IVDU
How do patients with a psoas abscess usually sit?
They dont like to extend their hip
=> they sit with it flexed
What muscles are thought of as secondary hip flexors?
RECTUS FEMORIS (1 of 4 heads of quadriceps)
SARTORIUS
Where does the rectus femoris attach to?
Origin: AIIS
Insertion: Tibia via patella tendon
Where does the sartorius attach to?
Origin: ASIS
Insertion: Tibia
What is an avulsion fracture?
- Injury to the bone in a location where a tendon or ligament attaches to the bone
- tendon or ligament pulls off a piece of the bone
Where do the hip adductors commonly originate, and where do they insert to?
Common origin: Inferior pubic rami
Insertion: Linea aspera
Pectineal line (P)
Tibia (G)
What muscles are classified as hip abductors?
GLUTEUS MINIMUS / MEDIUS
Where do the gluteus minimus and medius originate and insert?
Origin: Iliac wing
Insertion: Greater trochanter of femur
Where does the tensor fascia lata?
Origin: Iliac crest
Insertion: Lateral tibia via iliotibial tract (ITB)
What muscle is classified as a hip extensor
GLUTEUS MAXIMUS
