Ch 9 MDT Hip, Thigh, Knee Flashcards
Occurs when the femoral head is displaced from the acetabulum
Hip dislocation
Posterior hip dislocations are most common at ___%
90%
Affected limb short, hip is fixed in adducted and internally rotated
Severe tenderness
Decreased ROM
Posterior Hip Dislocation
Hip held in abduction and external rotation
Severe Tenderness
Decreased ROM
Anterior Hip dislocation
Diagnostic tests for hip dislocations
Radiograph of hip, knee, pelvis
CT scan to evaluate for fracture pattern
Treatment for hip dislocation
MEDEVAC
Reduction
SIQ until evaluated by Ortho
Mostly caused by high energy trauma
Severe pain in thigh
Unable to bear weight
Obvious deformity and edema
Fracture of the femoral shaft
Diagnostic tests for Femoral Shaft Fracture
Plain films of Hip, Knee, Pelvis, Femur
Treatment for Femoral Shaft Fracture
Immediate splinting and traction
MEDEVAC
Surgery
Occurs in patients who undergo repetitive impact
-Military recruits, athletes, runners
Vague pain in anterior groin or thigh, relieved with rest
Member increased their activity load
Stress Fracture of the Femoral Neck
Physical Exam:
- Antalgic gait
- Tenderness to proximal thigh/groin
- Limited ROM, particularly internal rotation
- Pain to groin or thigh with straight leg raise
Stress Fracture of the Femoral Neck
Diagnostic tests for Stress Fracture of the Femoral Neck
Bone scan/MRI
Treatment for Stress Fracture of the Femoral Neck
Analgesics
Ortho Evaluation
Activity Modification
-Crutches/Non-weight bearing
Pain in groin area with attempted weight bearing
Sensation of “coming apart” at the hip with bearing weight
High impact trauma
Fracture of the Pelvis
Diagnostics for Fracture of the Pelvis
Radiographs: Pelvis, hip, head, cervical, chest
UA: Hematuria is common
Hematocrit to evaluate blood loss
Treatment for Fracture of the Pelvis
MEDEVAC
Hemodynamic resuscitation
Activity modification, no weight bearing
Pain Management, Narcotics
PELVIC BINDER
Strain to muscles around the hip
-Iliopsoas, Sartorius, Rectus Femoris
Vigorous muscle contraction while muscle is stretched causes the injury
Pain over muscle exacerbated by activity
Hip Strain
Mild ecchymosis or edema
Tenderness to affected hip muscle
Increased pain while attempting to range the hip
Strength limited by pain, 4/5
Thomas test indicated for hip flexor tightness
Hip Strain
Diagnostics for Hip Strain
Plain films of pelvis and hip considered
MRI for chronic pain/unclear diagnosis
Treatment for Hip Strain
Light duty/Activity modification
NSAIDs
Pain free stretching and strengthening
Run-walk program
Injury happens when actively contracted muscle is put on a stretch
More often hamstrings are injured vs. quadriceps
Thigh strain
Hamstring strain typically reports a sudden onset of posterior or thigh pain that occurred while running, water skiing, or some other rapid movement
“Pop” perceived at the onset of pain
Quadriceps strains are associated with direct blows during contact sports resulting in a contusion
Thigh Strain
Physical Exam:
- Ecchymosis is common
- Tenderness to palpation to affected muscle group
- Pain while attempting to flex/extend at the knee
Thigh Strain
Diagnostics for Thigh Strain
X-rays if suspicion of fractures
MRI or ultrasound can confirm but is rarely indicated
Initial Treatment for Thigh Strain
Prevent further swelling and hemorrhage by having patient rest and elevate limb while applying ice and compressive wraps
Treatment for Thigh Strain
RICE
Pain free stretching and strengthening
NSAIDs
Inflammation and hypertrophy of the greater trochanteric bursa
Lateral Hip pain
Trochanteric Bursitis
Trochanteric Bursitis can be associated with:
Lumbar spine disease
Intraarticular hip pathology
Significant limb-length inequalities
Inflammatory arthritis
Previous surgery around the hip
Pain and tenderness over the greater trochanter (lateral hip)
Pain may radiate distally to the knee or ankle or buttocks
Pain is worse when going from sitting to standing
May decrease after warming up but return after 30-60 minutes of walking
Unable to lay on affecting side
Trochanteric Bursitis
No deformities on exam with point tenderness on lateral hip
Patient has increased pain with adduction or abduction with internal rotation
Trendelenburg and Faber tests are positive
Trochanteric Bursitis
Diagnostics for Trochanteric Bursitis
Hip radiographs are not necessary
-Used to rule out bony abnormalities
Treatment for Trochanteric Bursitis
NSAIDs
Light duty - Activity modification
Hip Strengthening (focus on abduction) and stretching
Refer to ortho if failed conservative management
Primary stabilizer of the knee
Anterior Cruciate Ligament (ACL)
Results from rotational (twisting) or hyperextension force
Sudden pain and giving way of knee
1/3 report audible “pop”
Had to stop playing sport because of instability/pain
ACL Tear
Generalized knee tenderness
ROM limited by pain/effusion
Locking/popping sensation
Positive Anterior Drawer and Lachman test
ACL Tear
Diagnostics for ACL tear
MRI
