boutonniere deformity
tear/stretch of the central extensor tendon at PIP
unopposed flexsion at PIP
extension at DIP
trauma or inflammatory arthritis
swan neck deformity
contraction of intrinsic muscle (trauma, RA)
*Extension at PIP
Rheumatoid arthritis
MCP swelling
swan neck deformities
ulnar deviation at MCP joints
nodules along tendon sheaths
heberden’s nodes
DIP
Bouchard’s nodes
PIP
strain
an overstretching or overexertion of some part of the musculature
sprain
a joint injury in which some of the fibers of a supporting ligament remains intact (graded I, II, III)
Spasm
abnormal contraction maintained beyond physiologic need
Bogginess
increased fluid in a hypertonic muscle; feels like a wet sponge
