Minimally Invasive Procedures

Image-Guided Navigation Surgery

Dr. Duff uses 3D exoscopic image guidance for navigated bone and tumour resections, allowing precise targeting of spinal lesions with minimal tissue disruption. The O-arm® and Stealth navigation system provide real-time 2D and 3D intraoperative imaging.

Minimally Invasive Discectomy

Removal of herniated disc material through small incisions using tubular retractors and microscopic or endoscopic visualisation. This approach significantly reduces muscle damage, blood loss, and post-operative recovery time compared to open surgery.

Transtubular Surgery

A signature technique in Dr. Duff's practice, transtubular surgery allows access to spinal lesions through a narrow tube rather than open incisions. He has published extensively on transtubular approaches for both cervical and thoracic pathologies.

Robotic-Assisted Spine Surgery

As a US patent co-holder in surgical robotics and a member of the team that developed a surgical robot at EPFL Lausanne, Dr. Duff has been at the forefront of robotic spinal surgery. Robotic assistance improves accuracy and reduces radiation exposure.

Minimally Invasive Decompression

Relief of nerve root and spinal cord compression through keyhole approaches. Particularly beneficial for elderly patients or those with comorbidities where open surgery carries higher risk. Dr. Duff advocates strongly for these techniques in advanced age groups.

Endoscopic Spine Surgery

Use of a small camera and instruments through a single port to treat spinal conditions. Endoscopic techniques offer the least invasive option for suitable cases, with reduced hospital stay, minimal scarring and faster return to normal activity.
