What muscles do these
movements?
List out the muscles that do each
movement:

• Hip Extension
• External Rotation
Observation
• Symmetry- hips, pelvis tilt (anterior/posterior)
– Lordosis or flat back
• Lower limb alignment
– Knees, patella, feet
– Genu Valgum/ Genu Varum
• Pelvic landmarks (ASIS, PSIS, iliac crest)
• Gait
– Walking, sitting - pain will result in movement distortion
Observation
• Anteversion (A)
and
• Retroversion (B)
• Think in terms of
the Greater
Trochanter
Observation
• Leg Length Discrepancy
– Anatomical
• Actual bone length difference
– Functional
• Rotation of pelvis

– 1/8 inch or greater = discrepancy
Special Tests
• Fracture
• Range of Motion
– Passive
– Active
– Resistive
Thigh Injuries
• Quadriceps Contusion
– Mechanism
• Blow to quads.
– Symptoms
•
•
•
•
Pain
Swelling
Bruising
Loss of function
– Treatment
• ME H
– Ice bent position
• The red is
hemorrhaging within
the compartment
• Increased swelling =
Increased pressure =
decreased healing/
function
• If hemorrhage gets too
large will have to do a
compartment release
which is done by
cutting the fascia to
allow the expansion
Thigh Injuries
• Myositis Ossificans
• Myo= muscle itis = irritation
– Mechanism
oss = bone
• Blow to thigh  Hemorrhage  hematoma

Hip Injuries
• Groin Strain
– Straining of Adductors
– Over stretching of the muscle
• Symptoms

- Compression wrap
Groin wrap
• Start with roll on MEDIAL side of leg
• Start ACE at an angle
– 2 times around with “dog ear”
• Apply extra tension going medially as to
pull the leg into ADduction.

- Athlete should fee leg being pulled in and
slightly forward.
****Anytime doing a hip wrap you will pull in
the direction that the injured muscles does.
