General Information about the
pelvis



This area of body is strong and stable
Great demand placed on this part of body—
”core”
Functions:




support the spine & trunk
Transfer weight to lower extremities
Place for muscle attachment of thigh and trunk
Protect organs of pelvic region

Fractures-Avulsion


Most common at ASIS or Ischial
Tuberosity

Avulsion Fractures




S/S:

bearing
POT (either over the ASIS or Ischial tub.)
Bleeding/discoloration
Avulsion

TX:



Ice
crutches
Medical referral for x-ray
Fractures- femur


Occurs most often in the shaft of the
femur
Mxn:

great force-direct or indirect- placed on the
femur
Femur Fractures

S/S:







Pain
POT
Deformity w/ thigh externally rotated,
shortened
Loss of motion/function
Swelling due to internal bleeding
Muscle spasms
Muscle lacerations
Femur fractures

Can be life threatening—fatty tissue and
bone marrow can get into the blood
stream and cause a blood clot
Femur Fracture

Tx:






Call 911
Don’t move the athlete
Hare traction splint
Check for distal pulse
Control any external bleeding
Treat for shock
Femur fractures
Femur fractures
Femoral Stress Fracture

Mxn: repetitive stress of the pounding of
the lower extremity which causes the
femur to bend (one side is compressed
the other is stretched)
Femoral stress fracture

S/S:




POT at one specific site
Pain with activity
Pain with a compressive force at the site
(sitting on edge of table)
Pain with activity
Femoral Stress fracture

Tx:




Rest
Alternate activity—non-weight bearing
Crutches if limping
Medical referral---x-rays and bone scan or--
Femoral stress fx
Slipped Capital Femoral
Epiphysis



Growth plate injury (epiphyseal fracture)
Occurs at the capital femoral epiphysis
(where neck joins the head of femur)
More common in boys 10-17 yrs.


Tall and thin
obese
Slipped Capital femoral
epiphysis

Mxn:


Not know but may be related to effects of a
growth hormone
In ¼ of cases both hips are affected
Slipped---epiphysis

S/S:

Pain in groin area that
arises suddenly as a result of trauma
 arises slowly over weeks or months as a result of
prolonged stress




Early signs minimal but later get pain in hip
and knee
Major limitations with movement
Limp when walking
Slipped --- epiphysis


TX:
Minor cases




Rest
Non-weight bearing to prevent further
slippage
Medical referral
Major cases

Surgery to repair “fracture” usually put pins
into bone to keep in place and allow for
proper healing
Slipped---epiphysis


Complications:
If displacement goes undetected or if
surgery fails to restore normal hip
mechanics can have problems later in life




Bone doesn’t grow properly
Head of femur doesn’t grow properly
Bone spurs
Arthritis
SCFE
SCFE
SCFE

Pins to fix
Legg-Calve-Perthes Disease





Disruption of blood flow to the head of
femur causing the bone tissue to die and
become flattened
Occurs in children 3-12 yrs
Occurs in boys 4 times more often than
girls
Usually occurs in first born
Affect usually only one hip
LCPD

Mxn: Unknown

S/S:


complaints of pain in groin, and sometimes
referred pain to abdomen or knee
Limited hip movement
LCPD




Tx:
Medical referral
Bed rest or non-weight bearing
If treated in time, the head of femur will
revascularize and regain its normal shape
(the old cells that die will be resorbed and
new bone cells laid down to take their
place)
LCPD
LCPD

Complications:

If not treated early enough, the head of
femur will be ill (abnormally) shaped
producing osteoarthritis in later life
Hip Dislocation



Rarely occurs in sports
Most are posterior
Mxn: traumatic force along the long axis
of the femur such as falling on one side
with the knee bent (and landing on that
bent knee) forcing head of femur
posteriorly
Hip Dislocation

S/S:




Hip in flexion, adduction, and internal rotation
Deformity posterior—head of femur can be
palpated through gluteal muscle
Extreme pain
Inability to move at hip joint
Hip Dislocation

Hip Dislocation





TX:
Call 911
Don’t move athlete
Splint in position you find them
Treat for shock
Hip Dislocation


Complications:
Tears in the vascular and nerve structures




Blood vessels to ligamentum teres may be
torn (as will the ligament itself)
Sciatic nerve may be damaged
Paralysis of muscles in the area
Atrophic necrosis (degeneration of femoral
head)
