3-D printed wrist splints for arthritis 

A Loughborough University lecturer has developed a computer software concept that will enable clinicians with no experience in Computer Aided Design (CAD) to design and make custom-made 3D printed wrist splints for rheumatoid arthritis sufferers. The 3D printed splints are not only more comfortable and attractive but potentially cheaper than the current ones that are 'ugly, bulky, and can make a patients arm sweat'.

The splints, which provide joint protection, rest, and promote pain relief,could be a major boost for sufferers of rheumatoid arthritis.

The splints are made by scanning a patient's arm in the 'appropriate position'. A 3D model splint is then designed based on the scan to generate a computer model.

The 3D printer can then produce as many splints as are needed at the touch of a button. They can be any colour, feature multiple materials, have a lattice design to aid ventilation and any type of fastening the patient requires.

The 3D CAD software prototype was shown to certified splinting practitioners, such as occupational therapists and physiotherapists.
