injections for pain. Prior to hip injecton, patients told
doctors where they felt pain:
 Buttocks: 71%
 Thigh: 57%
 Groin: 55%
 Lower leg: 22%
 Foot: 6%
 Knee: 2%

Abdominal exam
Obturator and Iliopsoas signs
Back exam

Hip joint problems can radiate to KNEE
Diagnostic Imaging
 Radiographs
 Anterior-Posterior view
 Frog leg view
 STANDING films to r/o early
OA




Bone scan: stress fxs
CT: subtle fractures
MRI: soft tissue, stress fx
Arthrogram: labral tears
Approach to hip problems
 Better anatomy knowledge  better
diagnoses
 Differentiate Anterior, Lateral, and
Posterior Hip Pain
 Develop an appropriate differential based on
the location and the exam
 Consider AGE in DDx

pain: An algorithmic approach J Fam Pract. 2003, 52:8

Specific Conditions
Osteitis Pubis
 Repetitive trauma to pubic symphysis due to
overuse
 Running/cutting, esp soccer, football, basketball
 S/Sx: insidious onset dull anterior groin pain;
may radiate; TTP over PS; +/- pain w/
resisted Adduction or passive Abduction
 Xrays helpful
 Tx: relative rest, brief NSAID, cross-tng,
stretching/strength rehab,
 consider steroid injection
Hip Pointer
 Contusion to the iliac crest
 S/Sx: pain, swelling, and
ecchymosis
 severe limit to motion
 +/- palpable hematoma
 Xrays to r/o fractures
 TX: rest, ice, compression,
?benefit from steroid/lido inj after
acute phase, progressive ROM,
strength rehab
 RTP: padding over area
Piriformis Syndrome
 Pain due to sciatic nerve
compression at piriformis
 Cause: trauma, prolonged
sitting, overuse; anomalies in
15-20%
 S/Sx:
 dull buttock pain +/- radiation
into leg
 TTP over mid-buttock
 Pain worse with passive IR or
resisted ER
-Tx: relative rest, ER stretching,
+/- steroid injection
Trochanteric bursitis
 Causes:
 friction between IT band, glut
medius/minimus/max and greater
trochanter; common in running w/
improper biomechanics and overtraining
 direct blows
 S/Sx:
 local pain, tenderness over the greater
trochanter
 Eval for leg length discrep,
adductor/abductor muscle imbalance,
hyperpronation
 Tx: relative rest, ice, brief NSAID, ITB
stretching, +/- steroid injection
 Address biomechanical defects above
Ischial bursitis
 Cause: excessive friction over ischial
tuberosity, or direct blow (hematoma, scarring)
 S/Sx: pain with sitting, TTP over ischial
tuberosity, pain w/ passive hip flexion and
active/resistive hip extension
 Xray to r/o fractures in traumatic hx
 Tx:
 Ice, padding, brief NSAID
 Prolonged: steroid injection
 Refractory: surgical excision
Iliopsoas bursitis
 Cause: overuse of hip flexors
 S/Sx:




anterior hip pain, +/- snap
preferred position of hip in flex/ER,
TTP to deep palpation anteriorly,
pain with passive hip extension
 Tx: relative rest, ice, brief NSAID,
stretching of iliopsoas,
 +/- steroid injection (preferably w/
guidance)
Sports “hernia”
 TTP lower abd wall
 No palpable hernias
 Co-incident injuries
 Adductor tendinopathy
 Osteitis pubis
 Imaging: consider MRI to
r/o other conditions
 Dynamic US helpful?
 Tx: relative rest, flexibility,
strength  surgery if
refractory
Muscle strains
 Adductors, gluteals, quads, hamstring tears
usually from overstretching during eccentric
contraction, esp when muscle fatigued
 Risk factors
 Early in season
 Muscle imbalance, inflexibility, inadequate warmup
 S/Sx: localized pain and TTP, +/- swelling or
ecchymosis , rarely palpable muscle defect,
and decreased ROM
 Graded I, II, III similar to sprains
 Xrays to r/o avulsion fxs if near muscle origins;
MRI if suspected complete tear
 Tx: PRICEMM, Rehab
(ROMstrengthcardiosport-specific tng)
Quadriceps Contusions
 Direct blow to muscle causes tissue damage
 S/Sx: localized TTP, +/-ecchymosis
 Grade I: knee flexion >90
 Grade II: knee flexion 45-90
 Grade III: knee flexion <45
 Tx: PRICE; avoid NSAID 48 hrs
 Max knee flexion, wrap in place 24 hrs
 Crutches, gradual WB, rehab (ROMstrength)
 RTP when FROM, 90%+ strength, activity w/o pain
 Complications:
 Compartment syndrome (acute)
 Myositis ossificans (chronic)
 Slowly enlarging mass, redness, increasing pain
 Xrays + 3-4 weeks, BS/US sooner
Stress Fractures
 Caused by repetitive overuse stresses
 RF’s: training errors, females, inadequate footwear,
intrinsic factors
 Pelvic, femoral neck, femoral shaft
 S/Sx: insidious pain w/ activity; +/- local TTP or
pain w/ hop test, +/- decreased ROM
 Xrays first, MRI or BS if neg but suspected
 Tx
 Femoral: immediate NWB, Ortho referral
 Tension sidesurgery
 Pelvic/femoral shaft: painless relative rest; graduated
WB, strength/stretching rehab, address other RF’s
Hip fractures
 Most common
through femoral neck,
various traumatic
causes
 S/Sx: pain, swelling,
and loss of function
 Involved leg
shortened and
externally rotated
 Tx: Ortho referral,
surgery
Hip Dislocation
 Femoral head usually goes
posteriorly
 common mechanism: knee to
dashboard during traffic collision
 S/Sx: extreme pain, obvious
deformity, unwilling to move the
extremity; position typically
flexion, adduction, and internal
rotation (FAdIR)
 Tx: emergent reduction in ER
under sedation (Ortho STAT!)
AVN of Femoral Head
 Causes:
 Trauma: fxs, hip dislocation, surgery
 Medical conditions (numerous)
 S/Sx: nonspecific hip pain, may radiate to knee;
exam may be relatively unremarkable, with decr
IR/ER as dz advances
 Xrays usually diagnostic >3mo duration; MRI or
BS if normal
 Tx: make pt NWB and refer to Ortho
 Conservative tx vs hip replacement depending on
severity
Conditions in adolescents
and children
Pelvic Apophysitis
THE PHYSICIAN AND SPORTSMEDICINE - VOL 29 - NO. 1 - JANUARY 2001
Pelvic Apophysitis
 Cause: overuse at tendinous insertion at
apophysis
 Iliac crest > ASIS, AIIS, lesser troch, greater
troch, ischial tuberosity
 S/Sx: localized pain, TTP, pain w/
passive stretch of attached muscle
 Xrays to r/o avulsion fxs
 Tx: relative rest (rare crutches), ice, brief
NSAID?, cross training, strength rehab,
flexibility
Pelvic Avulsion Fractures
 Caused by violent contraction of the attaching
muscle in skeletally immature athlete
 Sprint, jump, soccer, gymnast, dancer, football
 Ischial tuberosity > AIIS > ASIS > iliac crest, lesser
troch, greater troch
 S/Sx: sudden pain +/- pop, poor ROM, local pain
and TTP +/- muscle bulging away from the
attachment
 Xrays needed to eval size/displacement
 Tx: PRICEMM, progressive rehab
 Ortho referral if displacement >2 cm
Slipped Capital Femoral
Epiphysis (SCFE)
 Slippage of femoral epiphysis laterally off
femoral head
 Most prevalent ages 9-15, esp overweight
 Bilateral up to 50%
 S/Sx: insidious poorly localized hip/groin
pain +/- radiation to knee, worse w/ activ
 May have limited IR
 Xrays usually diagnostic; MRI early if neg
but dz suspected
 Tx: immed NWB, Ortho referral, surgery
Kline’s Line: tangent to superior femoral neck on
AP view
Abnormal:
Less or no
transsection
of physis
Normal
transsection
of physis
Legg-Calve-Perthes Dz
 Avascular necrosis of proximal femoral epiphysis
 Most prevalent ages 4-9, males 4:1
 Develops slowly
 S/Sx: intermittent deep hip pain worse w/ activity,
+/- radiating to groin, ant/med thigh, knee;
 limping, decreased ROM, and hip flexor tightness may
be noted
 Xrays usually diagnostic: MRI or BS early if xray
neg but AVN suspected
 Tx: Ortho referral; crutches, pain meds
Acute Transient (“Toxic”)
Synovitis
 inflammatory process of hip w/ chronic irritation
and excess secretion of synovial fluid within
the capsule; ? cause
 Most common dx in limping child <10, but it’s a
Dx of exclusion;
 r/o septic arthritis, SCFE, stress fx, etc.
 Xrays normal; MRI helpful ruling out other causes
 Labs: normal CBC, CRP
 S/Sx: pain w/ walking, low-grade fever
 Tx: relative rest, analgesics
Conclusion
 Know your anatomy
 Know why you’re doing an exam
