Mrs. Marr
Injuries• Remember that most
injuries fall into basic categories :– Contusions– Sprains
• Ligaments
– Strains• Muscles
– Fractures
– Chronic vs. Acute
Bones of the Bones of the Lower LimbLower Limb
Pelvis (hip): 3 bones that have grown togetherShaped differently in males than
femalesIlium you can feel it at the top of
your hipsIschium you sit on the boney tips Pubis located above your groin
Sacrum: back of hips, attached to ilium, base of the spine, 5 fused vertebrae
Coccyx: 4 bones at end of sacrum Acetabulum: Socket for the Femur
(Ball and Socket joint)Upper Leg:
Femur ThighboneKnee: Patella- knee bone
Joint- Femur and TibiaLower Leg: 2 bones
Tibia- weight bearing Fibular- non weight bearing
Ankle/Foot: Bottom of your toes 7 tarsal Bones
Talus: Ankle Bone Calcaneus (Heel Bone)
Largest/strongest bone in your footCuboid- cubed shapedNavicular- shaped like a little boatCuneiforms (3)- wedge shaped,
between Navicular & 1st 3 metatarsal
Hip and Pelvis Anatomy
Knee Anatomy• Hinge Joint
– Knee Flexion• Hamstrings
– Knee Extension• Quadriceps
• Bones– Femur– Tibia– Patella
• Fibula is not really in the knee complex
• Ligaments (4)– ACL– PCL– MCL– LCLThese ligaments connect
the Tibia and Femur and provide the structural integrity to the knee.
• Meniscus– Medial and Lateral
• Muscles– Quads (4)– Hamstrings (3)

Evaluation• History
– Asking what where when how
– Getting athlete comfortable
• Observation– Look for any
abnormalities
• Palpation– KNOW YOUR ANATOMY!
• Special Tests– ROM– Stress tests
Ober Test IT Band Tightness
Positive Test: The leg will not drop there is tightness
Negative Test:The leg drops easily
Lachman’s Test (ACL)
• Alternative ACL Test– Anterior Drawer – Modified Lachman’s
– Forward translation of the Femur on the Tibia
Posterior Sag (PCL)• Can also be done with
heel resting on chair• Look for sag of the Tibia/
Backward translation of the Tibia
Stress Test Valgus Varus
MCL LCL
Surgery
OTHERWound Care
• Put gloves on– Universal
Precautions
• Clean the wound• Antibiotic cream• Cover • Wrap on

KNEE/Hip LabKNEE/Hip LabLabel and Palpate
• Label the Lower Limb– Bones– Ligaments– Tendons/ MusclesYES YOU NEED TO MARK ON THEIR LEGS !
• Palpate and get a feel for the Knee and Hip– Always compare~ Touch BOTH Knees.
• SM II- Practice special tests-Knee– Anterior Drawer Test– Lachman’s/Modified Lachman’s Test– Varus Stress Test– Valgus Stress Test
• DON’T FORGET ABOUT THE ANKLE,FOOT, TOESDON’T FORGET ABOUT THE ANKLE,FOOT, TOES
