Mr Grainger is a full-time spinal surgeon and was appointed in 2004. He graduated from the University of Manchester in 1992 and after initial post graduate experience in the North West, he carried out his basic orthopaedic and spinal training in the West Midlands which was consolidated by the combined Orthopaedic/Neurosurgical Liverpool Spinal Fellowship in 2003.

His practice encompasses a comprehensive range of spinal conditions covering all levels of the spine including surgery for spinal cord and nerve root compression, other degenerative conditions including degenerative malalignment, spinal trauma and infections. Consequently, he is experienced in all surgical approaches to the spine and instrumentation techniques. He has an interest in reconstructive surgery of the spine and is a nationally recognised expert in surgery for tumours of the spinal column, in particular en-bloc resections for primary bone tumours. He undertakes a limited amount of intradural and paediatric deformity surgery.

Mr Grainger reviews articles for the European Spine Journal and has lectured and taught both nationally and internationally. He advises local teams on management of spinal conditions in professional sportsmen.
