Function of Pelvis Transmit weight from axial skeleton to LE
when standing or to ischial tuberosities when sitting Provides attachments for various muscles that
insert onto and control LE House parts of digestive and urinary tract Houses reproductive systems

Bursitis Most frequent location is
over lateral hip Greater trochanteric
bursitis Tenderness lateral hip Made worse by walking,
running, or twisting hip Insufficient stretching or
warm-up Treatment:
Limit activity Stretching exercises Ice & ice massage NSAIDs
![Page 26: Hip and Pelvis Chapter 19. Hip & Pelvis Strongest articulation in body Most stable articulation Well protected & surrounded by muscle on all sides](https://reader031.vdocuments.mx/reader031/viewer/2022032307/56649cc35503460f9498b072/html5/thumbnails/26.jpg)
Fracture 3 classifications:
Femoral neck Intertrochanteric Subtrochanteric
Causes: Falling (elderly) Extreme trauma (car
accidents) Impact injury
(athletics)
Signs & Symptoms Leg may appear
abnormally rotated Cannot move hip
without pain X-ray to confirm
Treatment Depends on fracture
type and medical condition

Quad & Hip Flexor Strain Common in those
sports that require jumping, kicking, or repetitive sprinting
Quad: rectus femoris Hip Flexor: rectus
femoris and/or iliopsoas
Treatment Ice Compression NSAIDs
Rehab Progressive Sport specific
![Page 29: Hip and Pelvis Chapter 19. Hip & Pelvis Strongest articulation in body Most stable articulation Well protected & surrounded by muscle on all sides](https://reader031.vdocuments.mx/reader031/viewer/2022032307/56649cc35503460f9498b072/html5/thumbnails/29.jpg)
Hamstring Strain Causes
Sudden, explosive starts and stops
Chronic overuse Making quick start or stop
when leg extended Overtraining (fatigued
hamstring muscles) Muscle imbalance (quad
muscles overdeveloped) Inflexibility Overstretched Insufficient warm-up,
stretching, or conditioning Direct blow while muscles
contracted
Signs & Symptoms Sharp pain (most
common in belly of muscle)
Bruising Swelling Loss of strength Feel or hear “pop”

Hamstring Strain Treatment
RICE Medication Physical
therapy/rehab Crutches Massage
Rehabilitation Progressive Weight-training Preventative
Proper stretching
Recovery Time Mild: 2-10 days Moderate: 10 days-6
weeks Severe: 6-10 weeks

Adductor Strain MOI: sudden sideways change in direction
Skating Soccer Track & field Tennis
Adductor longus Treatment:
Difficult to treat Risk of re-injury is high Rest, ice, anti-inflammatory meds Stretching & strengthening exercises
![Page 32: Hip and Pelvis Chapter 19. Hip & Pelvis Strongest articulation in body Most stable articulation Well protected & surrounded by muscle on all sides](https://reader031.vdocuments.mx/reader031/viewer/2022032307/56649cc35503460f9498b072/html5/thumbnails/32.jpg)
Treatment Lateral knee pain Pain worse after running
Especially after climbing hills/stairs
Often not present until mid-way through run
Associated with “snapping hip”
Attributed to: Over-training
Doubling mileage Increase in hill repeats
Running on uneven roads Tight indoor tracks Poor running shoes
Address faulty pelvic mechanics
Reduce or stop running Cross-train
Ice Stretch Gluteals and TFL Self-massage outside thigh
and/or gluteals Address faulty foot
mechanics, running shoes, or orthotics
Return to running gradually
Iliotibial Band Syndrome

Quadriceps Contusion Direct blow to thigh from helmet or knee
Football, rugby, soccer, basketball Limit motion Affect gait Severity graded by ROM at time of injury Treatment
Immediate compression, ice, NWB Massage contraindicated
Recovery Time: 2 days to 6 months Complication: Myositis Ossificans
![Page 34: Hip and Pelvis Chapter 19. Hip & Pelvis Strongest articulation in body Most stable articulation Well protected & surrounded by muscle on all sides](https://reader031.vdocuments.mx/reader031/viewer/2022032307/56649cc35503460f9498b072/html5/thumbnails/34.jpg)
Myositis Ossificans
Signs & Symptoms Treatment
Hard, painful mass in soft tissue
Progressive loss of knee flexion
X-ray at four weeks
Heat Limit joint motion Rehab exs limit pain Discouraged 6months:
Passive stretching Vigorous exercise
Calcium reabsorbtion may take 3-6 months
Ossifying mass (calcium deposit) forms within the muscle
Result of recurrent trauma to quad muscle that was not properly protected after mild injury

Iliac Crest Contusion “hip pointer” Caused by direct blow to hip Common in football due to improperly fitted
hip pads Signs & Symptoms:
Extreme tenderness Swelling Ecchymosis
Treatment Ice, compression Pad injured area
RTP: dictated by athlete’s pain level

stress Repetitive action of running
Chronic muscle strains Stress fractures Tendonitis
Overuse/overload fatigue within the tendon Snapping hip
Iliopsoas tendon snapping over the head of the femur Bursitis
CROSS-TRAINING

Chronic, ill-defined pain over groin and thigh Initially diagnosed with muscle strain Symptoms do not resolve with rest & rehab
Treatment: Rest Non-weight-bearing endurance exercises
