Fractures or (“broken bones”) obviously requires specialist immobilisation to allow optimum healing at the joint. A fracture will usually be confirmed by an X-ray or scan.
You can be sent to physiotherapy as a post-operative patient if they need to stabilise the fracture, or for “conservative” management, which means that it would be treated by immobilising the broken bone and joints on either side of it.
This can be done in a number of ways such as a plaster cast, usually at the hospital.
A custom made thermoplastic splint can also be made for you at Witty, Pask and Buckingham by Charlotte Saunders. The advantages of the splints are they are a lot more lightweight than a plaster cast and can be loosed/tightened to adapt to the amount of swelling, or even removed for care of any wounds to the soft tissue sustained from the injury or surgery.
They can also allow better movement of the unaffected joints to stop the whole hand becoming stiff/weak if possible.
When the hand is allowed out of splint or cast (usually guided by your consultant or fracture clinic) then physiotherapy is very effective at helping you regain your strength and movement again and then back to function.
