Chapter 82 - Arthritis and Arthroplasty of the Elbow Flashcards
unique things about elbow osteoarthritis
- joint space relatively preserved
- characterized by osteophyte formation, capsular contracture, loose bodies
- male»female (4:1)
- radiocapitellar joint involvement»_space; ulnohumeral joint involvement
if night pain present in elbow arthritis what should be considered?
inflammatory arthritis
what motion is affected first in elbow arthritis
- flexion/extension - pain is felt at extremes of motion
- pronation/supination relatively preserved
what protects the median nerve and brachial artery during capsular procedures
brachialis muscle
olecranon osteophytosis exists in what plane?
NOT just at the tip of the olecranon
olecranon osteophytosis extends medially and laterally and resection must address all of that to allow maximum extension and prevent impingement
coronoid osteophytosis exists in what plane?
NOT just at the tip - extends medially as well - required medial extension to prevent impingement
pathoanatomy in rheumatoid of the elbow
- intense synovitis that distends the joint
- FIXED flexion contracture
- attenuation of the soft tissues with associated instability
- radial head instability - laxity of the annular ligament
- ulnar>radial neuropathy
linked TEA implants
“sloppy hinge”
- SOME varus/valgus laxity
- concern for early prosthetic loosening, esp with very active patients
unlinked implants
- not joined in any way
- stability is provided by soft tissues
- instability is the main concern with this construct
in patients with inflammatory arthritis or other soft tissue attenuation processes what type of TEA must you use?
LINKED
- cannot rely on the soft tissues like you do in an unlinked prosthesis
When is a TEA contraindicated?
- active infection
- Charcot
