The Hip
Sports Med 2
The Hip

A ball and socket joint
 Hip transmits the load
from the foot to the
spine and vice versa
Blood & Nerve Supply
 Femoral
artery
 Common Iliac Vein
 Femoral Nerve
 Sciatic Nerve


Largest nerve in the body
Innervates thigh and lower leg
Bursae
 Iliopsoas

and deep trochanteric bursae
Most important ones
Injury
 Trochanteric



Bursitis
MOI:
• Common at the greater trochanter, high in women w/
increased Q angle, or leg length discrepancy
• Inflammation of bursa, or insertion of gluteus medius, or IT
band
S/S:
• c/o pain on lateral hip

TX:
• PRICE, NSAIDS, ROM, PREs, no inclined running
Special Tests: Obers,
Ober’s Test
-Athlete
lays on unaffected
side
-Knee flexed at 90 degrees
-Lift top leg into abduction,
slight hip extension
-Allow the affected leg to
drop into adduction
-If
leg does NOT drop = +
tight IT band
Bones

Sacrum, Coccyx


Pelvis




Innominate bones:
ossify and fuse early in
life
Support the spine and
trunk
Transfer their weight
to the lower limbs
Placement for bony
attachment

The acetabulum is
cushioned by the labrum
Hip Joint

Made of femur head and
acetabulum
Padded at the center by a
mass of fatty tissue,
ligaments and capsule
Ligaments

A bridge to allow blood
vessels and nerves to
enter the head of the
femur
Injuries

planted and trunk forced in opposing direction

S/S

down back of gluteus and hamstring
• Asymmetrical ASIS/PSIS or leg length difference

TX
• Modalities, brace, stability exercises

Special Test: FABERS/Patricks
FABERs /Patrick Test
Procedure: Place foot on
the opposite extended knee
of the painful SI joint
Apply pressure downward
on the bent knee.
Positive test: Pain felt in hip
or SI jt. = SI joint
dysfunction
Muscles
 Anterior

Iliacus
• Triangular shaped, flexes the hip

Psoas (major and minor)
• Flexes the hip

Sartorius
• Crosses medially across the
anterior aspect of the thigh
• Hip flexion, and external
rotation

Rectus Femoris
• Hip flexion and knee extension
Muscles
 Lateral

Tensor fascia latae
• Hip abduction
 Posterior

3 gluteal muscles
• Gluteus Maximus: extension,
adduction, helps us get up from
a sitting position
• Gluteus Medius: abduction
• Gluteus Minimus: abduction

Hamstrings: hip extension, knee flexion
• Biceps Femoris, Semitendinosis, Semimembranosus
Muscles
 Medial
All act as adductors and
rotators of the hip

Pectineus
• Adducts, flexes, external
rotation

Adductor longus, brevis and
magnus

may feel it the next day
• Pain, weakness, internal bleeding

TX
• PRICE, analgesics, ROM and strengthening exercises
• Rest has been the best treatment, protective spica

Special Tests: MMTs
Thomas Test
Procedure: Athletes lies supine
legs together
ATC places on hand under
athletes lumbar curve

chest flattening the spine.
Return bent leg to extended
position, lumbar curve should
return.
Positive Test: Extended thigh
should be flat on the table, if
not = tight hip flexor
Kendall test
Procedure: Athlete
lies supine with
knees off table
Athlete brings one
leg to their chest
Positive Test: If
thigh comes off the
table = tight hip
flexor

TX: flx w/ice pack ,PRICE,NSAIDS, crutches
Injury
 Myositis

Ossificans Traumatica
MOI:
• Severe blow or repeated blows to thigh, usually the
quadriceps
• Can lead to ectopic bone production (myosositis

• Pain, swelling, decreased function

TX:
• Conservative, surgery one year later

Special Tests:
• AROM knee flexion/ext
Injury
 Hamstring

Strain
MOI
• Most common injury to thigh, exact cause is not
known
• Possible MOI: muscle fatigue, faulty posture, leg
length discrepancy, tight hamstrings

S/S
• Hemorrhage, pain, loss of function.
• 3 grades of strain

TX
• PRICE, NSAIDS, very conservative, PREs

Special test: MMTs
Hamstring MMT
Injury
 Snapping

Hip:
Excessive repetitive movement in dancers, gymnasts,
hurdlers, sprinters

MOI:
• Imbalance in muscle
• IT band moves over the greater trochanter

S/S:
• c/o of snapping with pain

TX:
• Ice, NSAIDS, ultrasound, then stretching
Trendelenburg’s test
Procedure: Athlete stands,
foot on the unaffected side
is lifted
Look at the iliac crest to
see if it stays level
Positive test: if unaffected
side is lowers
OR
If standing on leg and
affected hip moves into
abduction
= Weak abductors
Measuring for Leg length

2 main ways:


Anatomical
discrepancy
Functional
discrepancy
Anatomical
discrepancy
(true method)
(actual bone is
shortened)
Athlete lies supine with
legs straight
Measurement is taken
between the medial
malleoli and ASIS
Bilaterally compare
Functional
discrepancy
Due to pelvic tilt or
deformity
Athlete lies supine, legs
straight
Measurement is taken
from umbilicus to the
medial malleoli
Bilaterally compare
