Orthopaedic Problems of the Hand Flashcards
(30 cards)
What elective hand conditions are there?
- Dupuytren’s Disease
- Trigger Finger
- De Quervain’s Tenovaginitis
- Nerve entrapments (Carpal Tunnel Syndrome, Cubital Tunnel Syndrome)
- Ganglion
- OA Base of Thumb
What is the epideminiology of Dupuytren’s?
- M:F 8:1 (15-64s)
- M:F 2:1 (75+)
Disease develops earlier in males
What is the aetiology of Dupuytren’s?
Autosomal dominant of variable penetrance
- Sporadic in 30% of cases
- Onset may be sex linked
- Almost exclusively white races
- Few sporadic reports in other races
What is Dupuytren’s associated with?
- Diabetes
- Alcohol
- Tobacco
- HIV
- Epilepsy
What are the features of Dupuytren’s diatheses?
- Early onset disease
- Bilateral disease
- Family history
- Ectopic disease
What is the pathophysiology of Dupuytren’s?
Myofibroblast
- Intracellular contractile elements
- Regulated by growth factors
- Production of collagen
What functional problems does Dupuytren’s present?
- Usually not painful
- Loss of finger extension (active or passive)
- Hand in pocket
- Gripping things
- Washing face
What are the treatment option for Dupuytren’s?
Non-operative
- Observe
- Splints don’t work
- Radiotherapy
Operative
- Partial fasciectomy
- Dermo-fasciectomy
- Arthrodesis
- Amputation
- Percutaneous needle fasciotomy
- Collagenase
What are the features of a partial fascieotomy?
- Most common procedure performed in UK
- Good correction can be achieved
- Wounds can take 2-3 weeks to heal
- Stiffness requires physiotherapy
- Can’t be cured
- Recurrence 50 % at 5 years
What are the features of a dermo-fasciotomy?
- More radical than partial fasciotomy
- Removal of skin may reduce recurrence rates
- Requires intensive physiotherapy
What are the features of a percutaneous needle fasciotomy?
-Quick
-No wounds
-Return to normal activities 2-3 days
-Does not prevent traditional surgery in future
-Higher recurrence
(? 50% at 3 years)
-Can be repeated
-Risk of Nerve Injury
What is the anatomy behind trigger finger?
- 2 tendons to each finger
- Tendons run in sheath
- Thickenings in the sheath are called pulleys
- Pulleys keep tendons close to the bone
- Swelling in tendon catches on the pulleys
Who gets trigger finger?
- F>M
- 40s-60s
- Ring > Thumb > Middle
- Repetitive use of hand ?
- Local trauma
- Associations: RA, DM, Gout
How is trigger finger diagnosed?
- Patient History
- Clicking sensation with movement of digit
- Lump in palm under pulley
- May have to use other hand to ‘unlock’
- ‘Clicking’ may progress to ‘locking’
What are the treatment options for trigger finger?
Non-operative
- Splintage
- Steroids
Operative
- Percutaneous release
- Open surgery
What history may a patient with de Quervain’s syndrome present with?
- Several weeks pain localised to radial side of wrist
- Aggravated by movement of the thumb
- May have seen a localised swelling
- Localised tenderness over tunnel
What is the epidemiology of de Quervain’s syndrome?
- M:F 1:6
- 50s to 60s
- Increased in post partum and lactating females
- Activities with frequent thumb abduction and ulnar deviation
What is the pathophysiology of de Quervain’s syndrome?
- 1st dorsal extensor compartment
- Fibro-osseous tunnel at the distal radius
- Thickening of localised segment
- 30% 1st compartment divided by septum
What examination should be done in Quervain’s syndrome?
- Examine thumb joints and consider base of thumb OA
- Finklestein’s test
- Resisted thumb extension
What are the treatment options for de Quervain’s syndrome?
Non-operative
- Splints
- Steroid injection
Operative
-Decompression
What is the anatomy of a ganglion?
- A myxoid degeneration from joint synovia
- Arise from joint capsule, tendon sheath or ligament
Who gets ganglia?
- F:M 2:1
- Peak 20-40 years
- Account for 70% of discrete swelling of the hand and wrist
- Dorsal> volar 3:1
What may ganglia be associated with?
Recurrent injury around the wrist
How is a diagnosis of hand/wrist ganglia made?
- Present with lump
- Firm, non-tender
- Change in size
- Smooth
- Occasionally lobulated
- Normally not fixed to underlying tissues
- Never fixed to the skin
