Upper Limb Arthritis Flashcards
How does OA usually present in the sternocalvicular joint?
joint swelling
pain
How are sternoclavicular and acromioclavicular OA usually managed?
physio
injection
excision (rare)
What other pathology is usually coupled with acromioclavicular OA?
Impingement
May be due to trauma
Shoulder OA of the glenohumeral joint is more common than arthritis of the Hip or Knee. TRUE/FALSE
FALSE
Hip/knee arthritis is more common
What can predispose to shoulder OA?
cuff tear
instability
previous surgery
idiopathic
What symptoms are usually apparent in shoulder OA?
- Pain
- crepitus (grinding)
- loss of movement (esp external rot.)
What are the complications of a shoulder replacement?
Infection Instability Stiffness Nerve damage Loosening
How do rotator cuff tears lead to OA of the shoulder?
Rotator cuff centres humerus on glenoid
=> If rotator cuff is torn, deltoid pulls head upwards
- Abnormal forces on glenoid from humerus in new position leads to OA
What is the point of a Reverse Geometry Shoulder Replacement?
- increases lever arm of deltoid
- lengthens deltoid
- resurfaces joint
- prevents upward migration of humerus
What types of arthritis is the elbow prone to developing?
RA and OA
Describe the difference between a rheumatoid X-Ray and an osteoarthritis X-Ray?
RA:
- Erosion
- Instability
OA: L - Loss of joint space O - Osteophytes S - Subchondral sclerosis S - Subchondral Cysts
Is it vital to replace the radial head in radiocapitellar OA?
Not necessarily
It is only a secondary stabiliser
What section of the humerus may be cut through if osteophytes are beginning to cause impingement?
The olecranon fossa
What is the downside to an elbow replacement?
Doesn’t last very long => not good for younger pts
Limited weight bearing to 5kg or 1kg repeatedly
What types of arthritis can be found in the wrist?
RA and OA
