How Are Spine
Conditions Diagnosed?

Before visiting a spine specialist, most patients would have experienced a history of symptoms that may have started suddenly or gradually worsened over time. They would have discussed their problem with their GP who may have called for some imaging test such as computed tomography (CT) or magnetic resonance imaging (MRI) to view discs, nerves and the spinal canal space. These patients may have received medical treatments or undergone one or more surgical procedures.

Your spine surgeon will consider your patient history and the information provided by your GP. These are critical resources to form a diagnosis. However, your specialist will also need to perform a physical exam, observe a range of movements or your standing posture to identify the cause of your symptoms. Your surgeon will have a discussion with you about your situation and will need to better understand how effective past remedies have worked for you.

In many cases, these sources of information and a consultation with you will provide sufficient information for your surgeon to form a diagnosis. However, sometimes additional medical investigations may be required and your specialist will discuss these requirements with you.

Look at this photo of a lovely person. Her smile says a lot and offers a clue about her life. However, to really know this person and know what lies behind that smile, you will need to talk with her. In a similar way, medical images provide doctors with information about a person’s medical condition but it does not give the whole story. While Images are essential to form a diagnosis, how the individual is affected by their medical condition as well as their needs and expectations are also critical to understand. In other words, your spine surgeon will need the whole story. Your surgeon will interact with you and consider your personal goals and needs in addition to what appears on a medical image. Only then a tailored treatment plan can be offered to you.

How Are Spine Conditions Treated?

For most patients a multidisciplinary approach is taken to develop a treatment plan. A personalised care plan may include non-operative treatment such as physical therapy or spinal injections. Your multi-disciplinary treatment may require a team of experts to work together. For instance, working with a physiotherapist through a series of exercises to increase flexibility and muscle strength.

Depending on your diagnosis and its severity, a treatment plan may include one or more of the following:

– Lifestyle modification
– Pain medication (prescription medication or over the counter)
– Physiotherapy
– Injections
– Brace/bracings
– Procedures

Types of Procedures

• Decompression
   – Discectomy
   – Laminectomy
• Fusion
   – Posterior
   – Anterior or both
• Disc Replacement

At Keat Ooi Surgery we provide the most advanced individualised care plan that is based on established guidelines, latest research and technological advancement.

What is Image Guided Technology?
During spine surgery, image guidance systems allow a spine surgeon to get a better look at a patient’s anatomy by allowing the surgeon to access real time, three dimensional and virtual images of the spine in relation to the surgical instruments being used intraoperatively. Such technologies and surgical tools that are available to spine surgeons are constantly evolving and improving over time.

How Has Technology Changed?
Historically, traditional image guidance systems have relied heavily on intraoperative fluoroscopy to successfully navigate the patient’s spine which means an increase in radiation exposure for the patient and surgical team. Now, 7D Surgical’s FlashTM Navigation System is the first image guidance system which virtually replaces standard fluoroscopy, providing the spine surgeon with a fast, accurate and radiation free tool to assist with the safe placement of spinal implants.

What is the 7D Surgical FlashTM Navigation System?

The 7D Surgical FlashTM Navigation System is a spinal image guidance system, which utilises a combination of machine vision technology and augmented reality to provide the surgeon with an accurate and radiation-free surgical tool. 7D Surgical utilises special cameras to analyse the surface of the spine in just seconds using only visible light.

With the 7D Surgical FlashTM Navigation System, your spine surgeon can visualise and better define the anatomy in 3D whilst operating.

7D Surgical achieves this by utilising the innovative machine vision technology, to digitally register the patient’s operative position with a pre-operative scan, to create a real-time 3D image of the patient’s anatomy for the surgeon to operate with accuracy and precision.

Finally, and most importantly, compared to traditional image guidance system, 7D Surgical can achieve this highly accurate visualisation in a matter of seconds for a seamless operative workflow, and with zero radiation exposure to the patient intra-operatively.

Benefits of the 7D Surgical FlashTM Navigation System to the patient and the surgical team:

· Eliminates intra-operative radiation to both the patient and surgical team.

· Superior 3D anatomy visualisation and effortless accuracy for the surgeon

· < 1 minute patient registration with ZERO Radiation – (Reduced from 30 minutes or more for traditional image guidance systems)

· Repeatable and efficient surgical workflow reducing anaesthetic and operative time for patients.

‘7D Surgical FlashTM Navigation System provides me an incredibly fast and efficient surgical workflow which allows me to cover the entire operative region without the need for additional fluoroscopy. The patient really benefits from this technology as it reduces the time of surgery and exposure to radiation when compared to other navigation systems.’
