Lower limb pathologies Flashcards
What hip pathologies do we need to know?
Arthritis
AVN
Trochanteric bursitis/gluteal cuff syndrome
What arthritises can affect the hip?
OA- primary or secondary to AVN, dysplasia, SUFE, Perthes
RA
Seronegative inflammatory
What is conservative treatment for hip arthritis?
Simple analgesia, physio, walking aids and weight reduction
When is surgery indicated for hip arthritis?
Hip replacement depending on pain levels
How long do hip replacements tend to last?
10-20 years
What can cause AVN in the hip?
Idiopathic
Trauma
Alcohol abuse
Steroids
How do you treat AVN in the hip?
MRI early on- Release pressure
Late on- damage done therefore replace.
WHat is trochanteric bursitis/gluteal cuff syndrome?
Tendonitis/tendon tears of gluteus medius insertion or trochanter bursa inflammation
How does trochanteric bursitis/gluteal cuff syndrome present?
Pain and tenderness over greater trochanter and pain on resisted abduction.
How is trochanteric bursitis/gluteal cuff syndrome treated?
Analgesia, anti-inflammatory, physio and steroids
No surgery!
Where does hip pain usually localise?
Groin but can radiate to knee
How does hip pain often present?
Decreased range of movement and increased pain on rotation.
What are the forms of arthritis found in the knee?
Primary OA
OA secondary to: Meniscal tears, ligament injury and malalignment.
Seropositive and negative arthritis
How do you treat arthritis in the knee?
Conservative- Analgesia and physio
Surgery- Partial or full knee replacement if in substantial pain
What are the complications of a knee replacement?
SImilar to hip but decreased chance of dislocation but increased chance of pain
What are the five soft tissue injuries of the knee we need to know?
Meniscal tears ACL rupture PCL rupture MCL tear LCL tear Combined ligament injury
What is a meniscal tear?
Tear in the meniscus usually due to twisting a loaded knee. Often occurs with ACL rupture
How does a meniscal tear present?
Pain on medial (commonly) or lateral joint line
Catching sensation
Locking- can’t fully extend
Effusion
Pain on tibial rotation (+ive Steinmann’s test)
What meniscal tear is most likely to produce locking?
Bucket handle tear
How do you treat a meniscal tear?
Limited healing due to poor blood supply
What is an ACL rupture?
Rupture of the ACL due to high rotation force turning body laterally.
How does an ACL rupture present?
Feel a ‘pop’ and develop haemarthrosis within an hour. Deep pain and knee gives way on walking.
+ive anterior draw test and Lachman test
How do you treat an ACL rupture?
Primary repair not effective so manage with physio.
If sports person reconstruct (tendon graft).
What is a PCL rupture?
Rupture of PCL due to direct blow to anterior tibia with knee flexed or hyperextended.
How to you treat a PCL rupture?
Reconstruct but not common
What causes a MCL tear?
Valgus stress injury- tackle from side
Get laxity and pain on valgus stressing
How do you treat a MCL tear?
Heals by itself but brace while doing so.
What causes a LCL tear?
Varus stress injury
How do you treat a LCL tear?
SUrgical repair or reconstruction but get lots of instability
What is a combined ligament injury?
Damage to 2+ knee ligaments. Often requires surgery.
WHat is the most important combined ligament tear?
Complete knee dislocation. This is an emergency due to potential for neurovascular injury!!!!!
What is an emergency knee situation?
Complete knee dislocation
What is an osteochondral injury of the knee?
Damage to the articular surface of the knee due to a direct blow.
How does osteochondral damage to the knee present?
Ongoing pain and effusion after injury
