ASHT - Dupuytrens, etc. Flashcards
(38 cards)
Convex Concave rule
Concave moving on convex: • Mobilize the concave joint in SAME direction as physiological movement ie. PIP jt • Convex surface moving on concave: • Mobilize the convex surface in OPPOSITE direction of physiological movement ie. carpals on radius
Dupuytren’s Cords - central
contracture of PIP and MP
Dupuytren’s Cords - spiral
contracture of PIP with neurovascular displacement
Dupuytren’s cords - natatory
digital webspace contracture
Dupuytren’s cords - commisural
contracture of thumb/index webspace
Dupuytren’s cords - retrovascular
contracture of the DIP (and sometimes PIP)
Dupuytren’s operative indications
≥30°MP contracture OR ≥20°PIP contracture with progression • Tabletop Test
Dupuytren’s medical management
• Needle fasciotomy: • Most effective with mild MP contractures, • High risk of nerve and tendon injury
• Closed enzymatic fasciotomy (Xiaflex): Collagenase injected into the cords, dissolving collagen bonds and weakening the cords then Manipulation into extension to rupture the cords – up to 7 days post injection • Limited open fasciectomy: • Diseased fascia is removed, rest is undisturbed McCash- a variation in which the skin is left open to heal by
secondary intention
• Dermofasciectomy: • Removing diseased fascia and overlying skin, treated with
grafting
• Open radical fasciectomy: • Removing diseased fascia and normal fascia
• Excision of nodule: • Only performed if nodule is superficial to trigger finger or if it is causing severe night pain
Dupuytren’s rehabilitation
• Pre-op visit • 1-3 days post op • Static extension orthosis • Full extension or no-tension protocol • AROM hourly • Edema control • Scar management • 3-4 weeks post op • Start strengthening

• Giant-cell tumor/xanthoma - tendon sheath • Hemangioma - vascular • Lipoma - fat • Neurilemmoma/Neurofibroma - nerve • Enchondroma - bone
malignant tumors
Squamous cell carcinoma - skin • Soft tissue sarcomas • Metastatic disease - rare in hand
