Sacroiliac (SI) Joint Radiofrequency Neurotomy

The SI joint receives pain signals through small sensory nerve branches, including the lateral branches of the sacral nerves and the L5 dorsal ramus. Radiofrequency neurotomy may be considered for selected patients with persistent SI joint pain when diagnostic assessment has established the joint as an important pain source and conservative treatment has not provided adequate relief.

Under X-ray guidance, specialised needles are positioned at carefully selected targets corresponding to the sensory nerves supplying the SI joint. After appropriate testing, controlled radiofrequency energy is used to create small thermal lesions that interrupt pain signalling from those nerves. The joint itself is not removed or structurally altered.

Because sensory nerve fibres can gradually regenerate, the benefit is not necessarily permanent, but suitable patients may experience relief for many months or longer. The aim is to make movement and rehabilitation more comfortable and reduce the impact of persistent SI joint pain on daily activities. Dr Danesh will assess your diagnostic response and anatomy before recommending treatment.
