Advice after your nerve block for surgery
On this page…
Introduction
One or more of the tendons that straighten your fingers have been repaired. If too much stress is placed on the tendon it is at risk of breaking (rupture).
This information sheet is a guide for the first 3 weeks after surgery. During this time your tendon is very weak and needs to be protected in two splints to reduce the stress placed on the tendon repair. The exercises are to move the healing tendon safely, to reduce the scar getting stuck to the skin (adhesions) and prevent joint stiffness.
Within your splint you are able to do light activities, but it will take at least 5 weeks before your tendon is strong enough to do any light activities without wearing the splints. It will be at least 12 weeks before you can return to contact sport or unrestricted use of your arm and hand.
Problems you may encounter
Please contact the therapy department should you experience any of the following problems:
- If you are unable to lift your finger/s, this may mean your tendon has ruptured.
- Increase in Swelling/Stiffness/Pain.
- Skin irritation/soreness or splint rubbing.
- If your hand or fingers turn blue, feel cold or tingle – check straps are not too tight.
- If the splint feels loose when swelling reduces.
Swelling
Swelling (oedema) is the body’s normal response to injury. It is important to minimise this by raising your hand as much as possible above the level of your heart and completing your exercises. Every hour move your arm, exercising your elbow and shoulder.
Skin Care
- Wash all areas not covered by the splints.
- Avoid wetting unhealed areas or dressings.
- Use moisturiser if your exposed skin becomes dry.
- When bathing/showering, cover you splints in a plastic bag taped to your arm. Keep your arm away from the hot water as this may alter the splint shape.
- If at any time you feel the splint is causing pressure or impairing your circulation, you must contact your therapist immediately.
Splint wear
Two thermoplastic splints have been made for you to wear to protect your hand after surgery.
These must be worn at all times for the next three weeks.
- Don’t take the splint off to bath, dress etc. as the repaired tendons may break.
- It 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.
- Don’t try to alter your splints in any way.
Hand use
You may use your hand for very light activities while keeping both splints on, such as getting dressed, doing zips and buttons, tying shoelaces and brushing your hair. We advise no driving until eight weeks after your surgery.
Precautions
Do not remove your splints for any reason (including when sleeping and bathing).
Do not lift anything heavy with your hand.
Do not drive or operate machinery.
Do not participate in any sporting activities.
Exercises
Complete all exercises 5 times every 2 hours with a 5 second hold.
