Indications

Minimally invasive tubular lumbar discectomy is indicated for patients with lumbar disc herniation causing radiculopathy or nerve compression who have not responded to conservative treatments, such as physical therapy, medications, or epidural injections.

Technique

The minimally invasive tubular lumbar discectomy procedure begins with the patient lying face down on the operating table.

A small incision is made on one side of the spine, through which a series of dilators are inserted to create a working channel. A tubular retractor is placed over the dilators to maintain the channel and access the affected area.

Using specialised instruments and working under a microscope, the surgeon removes the portion of the intervertebral disc that is compressing the spinal nerves. Once the nerve compression is relieved, the tubular retractor is removed, and the incision is closed with sutures or staples.

Benefits

• Reduced tissue damage: The tubular retractor system minimises disruption to the surrounding muscles and soft tissues, resulting in less postoperative pain and faster recovery times compared to traditional open surgery.
• Smaller incisions: A minimally invasive tubular lumbar discectomy requires only a small incision, which reduces scarring and lowers the risk of infection.
• Lower risk of complications: Due to the minimally invasive nature of the procedure, there is a lower risk of complications such as blood loss, infection, and muscle damage compared to traditional open surgery.
• Shorter hospital stays: Patients who undergo minimally invasive tubular lumbar discectomy typically have shorter hospital stays and faster return to normal activities.
• Preservation of spinal stability: By accessing the spine through a small incision and avoiding extensive dissection of the surrounding tissues, the procedure preserves the structural integrity of the spine and reduces the risk of spinal instability.

Risks

As with any surgical procedure, there are potential risks associated with minimally invasive tubular lumbar discectomy. These may include infection, bleeding, nerve damage, dural tears, or recurrent disc herniation.

However, the overall risk profile is generally considered lower than that of traditional open surgery.

Minimally invasive tubular lumbar discectomy offers a less invasive and more efficient approach to treating lumbar disc herniation.

Utilising a tubular retractor system and performing the discectomy through a small incision minimises tissue damage and results in shorter recovery times than traditional open surgery.

With its numerous benefits and reduced risk profile, minimally invasive tubular lumbar discectomy is becoming an increasingly popular option for patients seeking relief from debilitating spinal conditions.

As technology and surgical techniques continue to advance, this innovative approach is expected to become the gold standard in treating lumbar disc herniation.
