Advice after your nerve block for surgery
On this page…
One of the tendons that bend your thumb has been repaired. At this stage the tendon is very weak and at risk of rupturing (snapping).
It will take at least 8 weeks before your tendon is strong enough to perform certain activities and at least 12 weeks before you can return to heavy activities.
Potential problems
Please contact the therapy department if you suffer any of the following problems:
- increase in swelling/stiffness/pain
- skin irritation/soreness
- the splint is rubbing
- the splint is too tight or causing pressure points
- your hand or fingers turn blue, feel cold or tingle
- check straps are not too tight
- the splint feels loose
- you are unable to move your thumb or finger/s.
Swelling
It is important to reduce any swelling as quickly as possible.
Keep your hand elevated as much as possible until the swelling has gone down. Every hour move your arm, exercising your elbow and shoulder.
Skin Care
- Wash all areas not covered by the splint
- Avoid wetting unhealed areas or dressings.
- Use moisturiser if your exposed skin becomes dry.
- When bathing/showering, cover your splint in a plastic bag taped to your arm. Keep your arm away from the hot water as this may change the shape of the splint.
Splint Wear
- Keep your splint on at all times until you are instructed to take it off. This will probably be at 4 weeks following your surgery.
- Don’t take the splint off to bath, dress etc. as the repaired tendons may break.
- The splint will only come off to change the dressings and adjust the splint by the Therapists.
- Avoid direct contact with heat, (e.g., radiators / hairdryers and the bath) as this may alter its shape.
Do not
- use your thumb for any activity (including buttons)
- lift anything heavy with your hand
- drive or operate machinery
- participate in any sporting activities
- push your thumb straight.
Exercises
Complete all exercises 10 reps every 4 hours, unless stated on your sheet. Only remove the minimal number of straps to complete each exercise.
