EMR Silverthorn in conjunction with the National Orthopaedic Hospital Stanmore are helping children walk again.
The children, who have lost parts of their leg bones after suffering bone cancer, are being helped with a revolutionary new procedure that eliminates the need for years of painful surgery.

Because a large amount of bone has been lost, a prosthesis is implanted into the patient’s leg to support the growing bone. As the bone grows, the implant must be extended as well. Previously, this involved further painful operations, often three or four a year over a five-year period, each bringing misery and pain for the patient and extra cost for the hospital.

The new procedure is non-invasive and involves placing a small magnetic rotor in the patient’s leg. This is linked to the prosthetic implant by a gearbox and is turned by an external stator. To increase the length of the prosthesis, the patient’s leg is placed inside the stator core. When energised, the stator turns the rotor at 3000rpm, which drives the gearbox and extends the prosthesis by one millimetre every four minutes. A typical treatment will extend the prosthesis by four millimetres over the course of the 16 minutes.

An excellent example of the innovative and diverse use of EMR Silverthorn knowledge and products.
