The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Extracorporeal shockwave therapy for refractory greater trochanteric pain syndrome.
The greater trochanter is the bony bump on the outer side of the hip. This area may become painful following hip surgery or as a result of inflammation of the fluid-filled sac (bursa) that allows smooth motion between bones and tendons or muscles. Such inflammation (bursitis) is often caused by minor repetitive trauma or a direct injury.
In extracorporeal shockwave therapy, a machine is used to deliver sound waves to the painful area. It is not known exactly how this works, but it is thought that it might stimulate healing.
