Q

Hip Dislocation

A

-Native hip dislocation -High energy trauma
-Total hip arthroplasty: Simple twisting motion
—Orthopedic emergency!
-Posterior is the most common
-May be associated with other injuries
Femoral neck fracture
Acetabular fracture

17
Q

Hip Dislocation exam and tx

A

-posterior-adducted, flexed, internally rotated
-Anterior-abducted, flexed, externally rotated
-Extreme pain with movement
-Tx
Immediate closed reduction
Repeat x-rays to assure proper reduction
Abduction brace – 60 degrees flexion and 15 degrees abduction
Surgical-if associated with fracture
Complications
Avascular necrosis
Sciatic nerve injury (posterior)
Femoral artery and nerve injury (anterior)
Instability and recurrence
Osteoarthritis
Heterotopic ossification

18
Q

Osteoarthritis

A

-Damage to articular cartilage
-May be due to trauma, infection, developmental, metabolic or idiopathic
Exam
—-Chronic hip/groin pain that is increasing over time
—-Decreased ROM
—-+ log roll test
—-May have flexion contracture with antalgic gait
Tx: NSAIDs, PT, Steroid Injection
-Operative-Total Hip athroplasty

19
Q

Inflammatory Arthritis

A

-Host immunologic response results in inflammatory response (gout, lupus, gout)
-Exam: pain & stiffness, may involve other joints, antalgic gait
-Tx: NSAIDs, PT
-Operative: Synovectomy - early, Total hip arthroplasty - late

20
Q

Avascular Necrosis

A

-Necrosis of femoral head-vascular disruption
-Associated with trauma, ETOH, steroid use, RA
-Exam: Increasing pain with internal and external rotation
-Tx: symptom control, Operative: Total hip arthroplasty

21
Q

Valgus Stress-Knee exam

A

Laxity – MCL injury

22
Q

Varus stress test-knee exam

A

Laxity – LCL injury

23
Q

Apley Compression-Knee Exam

A

-Pain, popping or clicking-meniscal injury/arthritis

24
Q

Lachman Test: Knee exam

A

Knee flexed to 20-30 degrees
Hand on femur/tibia
Laxity – ACL injury

25
Q

Anterior Drawer Test: Knee exam

A

Knee flexed to 90 degrees
Pull tibia forward
Laxity – ACL injury

26
Q

Knee Dislocation

A

-Rare – ORTHOPEDIC EMERGENCY
-Usually high energy injury
-Ligaments and other soft tissue disrupted
-May be associated with other injuries
-High incidence of neurovascular injury

27
Q

Patellofemoral Syndrome

A

-Damage or softening of the patellar articular cartilage
-Runner’s knee
Multiple etiologies: Trauma, Dislocation, Malalignment

28
Q

Compartment Syndrome

A

-Trauma to thick, closed fascial compartments
edema or hemorrhage
inability to expand
creates high pressures leading to:
decreased tissue perfusion,
necrosis
loss of function
-PAIN
-Paresthesia-most reliable
-Increased pressure-greater than 30
-Paralysis-late sign
-Pallor/decreased pulses-late sign.

Q

Compartment Syndrome

A

-Trauma to thick, closed fascial compartments
edema or hemorrhage
inability to expand
creates high pressures leading to:
decreased tissue perfusion,
necrosis
loss of function
-PAIN
-Paresthesia-most reliable
-Increased pressure-greater than 30
-Paralysis-late sign
-Pallor/decreased pulses-late sign.T

30
Q

Treatment of Compartment Syndrome

A

-Elevate to level of heart-not above-too high decreases arterial flow
-Remove splints/casts/circumferential dressings
-Correct hypotension
-Fasciotomies - w/in 12 hours to prevent ischemia
release of compartments
delayed closure
possible skin graftingq
