Exam 4 Clinical Flashcards
- More common in female infants
- Majority of children w/ this condition have ligamentous laxity which causes the hip to become unstable & slip out of position
- Majority of infants w/ the condition were in a breech position during the birth process
Developmental Dysplasia (congenital dislocation)
Long term effects from:
- Pain
- Abnormal gait
- unequal leg length
- osteoarthritis
- twisting of the femur (femoral anteversion)
- Contracture of the hip muscle
Developmental Dysplasia (congenital dislocation)
- Most common, which allows the femoral head to pass through a tear in the capsular ligament & over the acetabulum, ending up on the ilium
- May compromise the sciatic nerve
Posterior dislocation of the hip joint
- Dislocation which allows the head of the femur to end up in the obturator foramen
- May compromise the obturator nerve
Anterior dislocation of the hip joint
- Caused by friction b/t the skin & the patella
- or direct blow or falling on a flexed knee
- If the condition becomes chronic, the bursae will become distended w/ fluid & form a swelling anterior to the knee
Prepatellar Bursitis (housemaid’s)
- Casued by excessive friction b/t the skin & the tibial tubercle
- AKA. “clergyman’s knee” but is common in roofers & floor tillers (wear knee pads to avoid)
Subcutaneous Infrapatellar
- Caused by bacteria from an abrasion or penetrating wound
- Infection may spread to the knee joint cavity, causing local redness & pain as well as enlarged lymph nodes
Suprapatellar Bursitis
Unhappy Triad refers to a blow to the lateral aspect of the joint while it is weight bearing & cause damage to what ligaments?
Medial collateral
Anterior cruciate
Medial meniscus
- Most commonly injured ligament of the joint
- Can occur not only by a lateral blow to the joint but also by rotational forces during trauma
Damage to the Medial Collateral ligament
- More vulnerable than lateral ____
- pt.’s complain of knee “clicking”, locking up, pain when going up stairs
- Small tears can sometimes repair themselves (4-6 weeks PT)
- Larger tears need surgery
- If large parts of the menisci are removed, forces are now transmitted to the condyles of the tibia & can lead to damage of the articular cartilage & lead to osteoarthritis
Damage to the medial Meniscus
- Damaged in sports that require twisting or jumping
- @ time of injury pt. may state they heard a popping sound, or say my knee gave out
- Knee becomes swollen, as the cavity fills with blood
- Will produce the tibia can be pulled excessively forward under the femur (positive anterior drawer test)
Damaged to the Anterior Cruciate lig.
- injured less often than the anterior cruciate
- Tibia can be pulled excessively backward under the femur (positive posterior drawer test)
Damage to the Posterior Cruciate lig.
- Used to replace diseased portions of the knee (both femoral & tibial portions)
- Can be total or partial
Knee replacements
- Disruption of the epiphyseal plate of the tibial tuberosity that occurs around puberty in active teens
- Ex. of what is known as apophyseal injury or a traction apophysitis
- Apophyses is a secondary ossification center that develops w/ growth
- bilateral in half of those affected
- pt. will complain of pain in the area of the tibial tuberosity
- Avulsion fractures of the tubercle are common
- Can take 1-2 years to run its course
Osgood- Schlatter’s disease
- Most commonly fractured bone of the lower leg
- Compound fractures are common from direct trauma
- Relatively poor blood supply, making fractures taking longer to heal
Fractures to the tibia
