Mr Pratipal Kalsi is an experienced consultant spinal neurosurgeon at Imperial College Healthcare NHS Trust. His special interests include complex spinal neurosurgery for adult degenerative spine disorders affecting the cervical, thoracic and lumbar spine, spine oncology and spinal trauma.

He undertook his medical training at Imperial College School of Medicine, before completing his training in neurosurgery and spinal surgery. He gained further experience in complex spine surgery by undertaking an international complex spine fellowship at the University of Toronto, Canada and the National Hospital for Neurology and Neurosurgery, Queen Square, where he consolidated his interests in adult degenerative spine disorders, minimally invasive spine surgery and spine tumours.

Pratipal undertook his PhD in spinal cord repair and regeneration at the Institute of Neurology, UCL, where he developed a model for spinal injury repair. He has a number of clinical and scientific research interests and has published his work in peer reviewed journals, presented at national and international research meetings and has written a number of book chapters on spine surgery.

He has been awarded numerous prizes for spinal surgery, including the Ronald Raven Barber Award for oncology surgery by the Royal College of Surgeons, a Scholarship to study complex spine surgery at University of California San Francisco and the Codman Travelling Fellowship.

Pratipal is a member of several spine associations including the British Association of Spine Surgeons, the Society of British Neurological Surgeons and AO Spine.
