Lab - Thigh, hip, groin, & pelvis anatomy Flashcards
Bones of Pelvis?
Femur
Innominate Bone (3)
- Ilium
- Ischium
- Pubis
All 3 meet to form the acetabulum = socket of hip joint
Sacrum
- sacrum and ilium meet to form the Sacroiliac Joints (SI -joint)
- Quite a mobile joint but also a pretty problematic joint
Pubic symphysis connects the pubic bones
Mscs in Anterior Thigh
Sartorius
Quadriceps
What Nerve innervates anterior thigh?
Femoral Nerve
Origin and action of the Sartorius?
Origin = ASIS
Action = flex/abd/ ext rotation
Origin of rectus femoris?
Anterior Inferior Iliac Spine
Posterior Thigh mscs
Popliteus
Hamstrings
- Semitendinosis (medial)
- Semimembranosus (middle)
- Biceps Femoris (Lateral)
Function of popliteus?
Unlocks knee
Medial Thigh mscs
- Gracilis
- Sartorius
- Pectineus
- Adductors (brevis, longus, Magnus)
What n. innervates the inner thigh?
Oburator n.
Blood supply in Thigh
Deep medial circumflex femoral a. –> primary blood supply to head + neck of femur
Deep femoral a. –> Largest branch of femoral a. Primary a. to thigh
Femoral a. –> goes through adductor Hiatus sp it goes from anterior to posterior and goes along back of knee
- primary artery to lower limb
- Becomes popliteal a. at knee
What is the Femoral TRIANGLE?
High groin
3 important structures inside
- Femoral n., a., & v.
Borders are the sartorius, adductor longus, and inguinal lig.
Only place where those 3 structures are more exposed/ at risk
Grading of quad contusions?
MOI = impact/ trauma
Grades 1-4
G1 = mild pain, minimal loss of function, fast recovery
G2 = mild bruise, mild TOP, Loss of function (knee flexion)
G3 = moderate pain/ swelling/ bruising, knee flexion = 45-90 degrees, limp, decreases ROM
G4 = Major disability, fascia may split, less than 45 degrees of flexion,
How to manage Contusions?
Early
PRICE
Stretch as able
NSAIDs
Maybe see doctor for G3/4
later on
- gentle AROM/ PROM - bike
- gentle stretch
- Ultrasound, msc stim, IFC
What is myositis Ossificans Traumatica?
Ectopic bone formation/ calcification (in msc) after severe blow
- results due to improper care of contusion or repeated trauma
S&S
- TOP, lump, decreased ROM
Causes of Quad/ hamstring strains?
inadequate warm up
msc imbalance (strength/ inflexibility)
Unexpected mvm
Neural tightness (sciatic or femoral)
Management of Quad/ hamstring strain?
Stage 1
- PRICE
- Physio (IFC)
Stage 2
- Ice: heat
- AROM
- PROM and gentle stretch
- RROM - low resistance
Stage 3
- prepare for R2P
- more sport specific drills
- more stretching/ more aggressive
- Jog/ run/ sprint
Acute Femoral Fractures?
Usually to the middle 1/3 b/c slight curve or the femoral neck (thinner), or superchondylar
EAP! and treat for shock
Very painful, deformation,
ORIF = open reduction, internal fixation
Femoral Stress # types ans symptoms and management?
Compression # (horizontal to trabelculae)
Distraction # (perpendicular to trabeculae)
persistant and night time pain
x-ray/ bone scan, PRICE, adjust training and decrease worsening activity
