Orthopaedic Hip Conditions Flashcards
Femur fractures may lead to what clinical observation?
Hypotension, especially in cases of major trauma- the femur has a large blood supply and if damaged can bleed significantly
Define osteoarthritis.
Degenerative change of synovial joints
->progressive loss of articular cartilage and secondary bony changes as a result
What is osteoarthritis characterised by?
Worsening pain and stiffness of the affected joint affecting day to day life
Trochanteric burtsitis?
Inflammation of the bursa found between the trochanter and the iliotibial band
F>M
What characterises bursitis?
Swelling
What are some of the causes of trochanteric bursitis?
Trauma
Over-use e.g. athletes or runners
Abnormal movements e.g. after surgery, muscle wasting, hip replacements, scoliosis
Presentation of trochanteric bursitis?
Pain- lateral hip
Swelling
What may be seen during MSK examination of someone with trochanteric bursitis?
LOOK- muscle wasting, previous surgery scars
FEEL- tenderness at greater tuberosity
MOVE- worst pain in active abduction, passive adduction painful too (crossing leg over)
Investigations for trochanteric bursitis?
X-ray- usually to exclude arthritis diagnosis
MRI- helps to confirm if not sure
Ultrasound- useful at localising it, sometimes used as US guided steroid injection
Treatment of trochanteric bursitis?
NSAIDs- topical and oral
Relative rest/activity modification
Physio
Corticosteroid injection
->sometimes surgery of bursectomy but rarely required
Avascular necrosis?
Death of bone due to loss of blood supply
Who is more likely to get avascular necrosis?
M>F
Average age 35-50 yrs
Risk factors which can lead to avascular necrosis?
Trauma; fracture, dislocation
Systemic; steroids, alcoholism, hypercoagulable states
Other conditions; lymphoma, sickle cell disease, leukaemia, Caisson’s disease
Which trauma related incident can lead to avascular necrosis?
Femoral head injury e.g. fracture
More displaced the fracture, the higher risk of avascular necrosis
How does intravascular coagulation lead to avascular necrosis?
Coagulation of blood, leading to venous thrombosis, increased pressure which reduces blood supply to bone and cells die
Symptoms of avascular necrosis?
Insidious onset of pain- gradual but with serious effects
Pain usually in groin, associated with stairs, walking uphill
Limp
Examination of a patient with avascular necrosis may be fairly normal but what may the symptoms replicate?
Early arthritis as reduced range of motion and stiff joints
Which investigation is best to confirm diagnosis of avascular necrosis?
MRI
->more sensitive and picks up 99%. X-ray only helpful if condition has progressed to the stage where the bone has started to collapse or become arthritic
