Orthopedic hip conditions Flashcards
What conditions are considered?
- OA
- Trochanteric bursitis
- Avascular necrosis
- Femoacetabular impingement
- Labral tear
What is Trocanteric bursitis?
Inflammation of the trochanteric bursa
What is the aetiology of Trochanteric bursitis?
1- Trauma
2- Over-use
-Athletes, often runners
-Repetitive movements
3- Abnormal movements -Distant problem • e.g. Scoliosis - Local problem •Muscle wasting following surgery •Total Hip Replacement •Osteoarthritis
Presentation of Trocanteric bursitis?
Pain in lateral hip and tenderness at greater trochanter
Worst pain at abduction
Investigations of trochanteric bursitis
- XRAY
- MRI
- Ultrasound
Treatment of Trocanteric bursitis
-NSAIDs
-Relative rest/ activity modification
-Physiotherapy :
•Correct posture
•Stretching
•Strengthen muscles around joints
-Injection of corticosteroids
-Surgery: Bursectomy
What Is avascular necrosis
Death of bone due to reduced blood supply
Risk factors for Avascular necrosis
1- trauma
- irradiation
- fracture
- dislocation
- iatrogenic
2- Systemic
- Idiopathic
- Hypercoagulable state
- Steroids
- Haematological e.g. lymphoma
- Caisson’s disease
- Alcoholism
Presentation of Avascular necrosis
- Sudden onset of groin pain
- Pain with stairs/ walking uphill
- Limp
Treatment of avascular necrosis
-Non-operative: • Reduce weight bearing • NSAIDs • Bisphosphonates • Anticoagulants • Physio
- Surgical
• Restore blood supply
Core decompression
Core decompression and vascularised graft
• Move the lesion away from the weight bearing area
Rotational osteotomy
• Total hip replacement
What is a femoacetabular impingement?
A condition in which extra bone grows along one or both of the bones that form the hip joint — giving the bones an irregular shape. Because they do not fit together perfectly, the bones rub against each other during movement. Over time this friction can damage the joint, causing pain and limiting activity.
What are the two broad categories of impingements?
CAM: femoral based impingement
-Usually in athletic males
PINCER: acetabulum based impingement
-Usually in athletic females
Presentation of impingement
- Groin pain which gets worse with flexion
- Blocked movement
- Pain with certain movements e.g. getting out of a chair, squatting, lunging
- Positive Fadir test
Investigation of impingement
XRAT
MRI
FADIR TEST: flexion, Adduction, internal rotation.
What is an impingement associated with?
- Labral tears and degeneration
- Cartilage damage and flap tears
- Secondary hip conditions
Treatment for impingement?
Non operative:
- Activity modification
- NSAIDs
- physiotherapy
Operative
- Anthroscopy : shave down the defect, deal with labral tears, resect artic cartilage flaps
- Open surgery : resection, periacetabular osteotomy, hip arthroplasty.
What is a labral tear?
tear to the labrum- the soft tissue which covers the acetabulum.
Aetiology of a labrum tear?
FAI Trauma OA Dysplasia Collagen diseases – Ehlers-Danlos
Presentation of a labrum tear?
- Groin or Hip Pain
- Snapping sensation
- Jamming or locking
- Positive FABER test
Investigation of a labrum tear?
-XRAY: OA, dysplasia
-MRI
-Diagnostic injection : local anaestetic to identify site of pain
FABER test
Treatment of a labrum tear?
Non-operative: - Activity modification - NSAIDs - Physio - Injection of steroids Operative -Arthroscopy: repair and resection
What is the most common type of labrum tear?
anterior superior tear.
