Minor hand conditions Flashcards
Define Dupuytren’s contracture
Progressive, painless fibrotic thickening of palmar
fascia.
What are the features of Dupuytren’s contracture?
Middle aged/elderly patients
Skin puckering/tethering
Fixed flexion contracture of ring/little finger
Often bilateral
MCP/IP joint flexion
Associated with ALD, DM, Smoking, epilepsy+meds
What is the management of Dupuytren’s contracture?
Conservative - physio/exercise
Fasiectomy - used when hand cannot be placed flat on surface, z scars to try and prevent contracture, but usually recurs. Ulnar nerve may be damaged
What are the differentials for a Dupuytren’s contracture?
Skin contracture due to old injury/burn
Tendon fibrosis/Trigger finger
Ulnar nerve palsy
Define Trigger finger
Tendon nodule which catches on tendon sheath. Triggering on forced extension → Fixed flexion deformity
What fingers are usually effected by Trigger finger?
Ring/Middle finger
Associated with RA
What is the treatment for Trigger finger?
Steroid injection - High recurrence
Surgery
Define Ganglion
Smooth, multilocular cystic swellings
May become in communication with joint capsules/tendons
What are the features of a Ganglion?
90% on dorsum of hand
Subdermal, fixed to deeper structures so limits movement
Can cause pain or nerve pressure symptoms
What is the management of a Ganglion?
50% go spontaneously
Aspiration ± steroid and hyaluronidase injection
Surgical excision
Differentials - lipoma, sebaceous cyst, fibroma
What is Volkmann’s contracture?
Ischaemia usually due to brachial artery damage causes muscle death in the forearm leading to contraction of the muscles and Volkmann’s contracture in the hand
