Unilateral Biportal Endoscopy (UBE) is a minimally invasive spinal surgery technique that uses two small incisions to access the spine. One opening is used for a high-definition endoscope and the other for surgical instruments, allowing the surgeon to directly visualise and treat certain spinal conditions while causing less disruption to surrounding muscles and tissues.
UBE can be used for selected conditions affecting the cervical, thoracic, and lumbar spine. Depending on the condition, the procedure may be used for nerve decompression, removal of a herniated disc, or treatment of spinal stenosis. The suitability of UBE depends on the patient’s symptoms, imaging findings, spinal stability, and overall clinical condition.
Conditions Treated with Unilateral Biportal Endoscopy
UBE may be considered for selected patients with conditions such as:
- Herniated or Slipped Disc: Removal of disc material compressing a spinal nerve.
- Lumbar Canal Stenosis: Decompression of narrowed areas of the spinal canal or nerve passageways.
- Foraminal Stenosis: Relief of pressure on a nerve root where it exits the spine.
- Cervical Disc Problems: In selected cases, endoscopic techniques may be used to decompress affected neural structures.
- Recurrent Disc Problems: Certain recurrent disc conditions may be suitable for endoscopic treatment following detailed evaluation.
- Selected Degenerative Spine Conditions: UBE may be considered when symptoms are caused by nerve compression associated with degenerative changes.
Benefits of Unilateral Biportal Endoscopy
As a minimally invasive technique, UBE may offer certain potential advantages in appropriately selected patients, including:
- Smaller skin incisions
- Reduced disruption of surrounding muscles and soft tissues
- Direct visualisation of the surgical area through a high-definition endoscope
- Ability to use conventional spinal surgical instruments through a separate working portal
- Potentially less postoperative discomfort in selected cases
- Earlier mobilisation in appropriate patients
- Smaller surgical scars
- Potentially shorter hospitalisation depending on the procedure and individual recovery
How is Unilateral Biportal Endoscopy Performed?
UBE generally involves two small portals:
- Viewing Portal: A high-definition endoscope with a camera is inserted through one small incision to provide a magnified view of the surgical area.
- Working Portal: Surgical instruments are introduced through a second incision, allowing the surgeon to perform the required procedure.
Depending on the condition, the surgeon may remove a herniated disc fragment, decompress a nerve, remove portions of bone or ligament contributing to stenosis, or perform another appropriate procedure.
The technique is performed under appropriate anaesthesia and with imaging guidance as required. The exact surgical approach depends on the location and nature of the spinal problem.
Diagnosis and Evaluation Before UBE
UBE is not automatically appropriate for every patient with back or neck pain. Careful evaluation is required before considering the procedure.
Assessment may include:
- Detailed medical history and symptom evaluation
- Neurological examination
- Assessment of muscle strength, sensation, reflexes, and gait
- MRI of the affected spinal region
- CT scan or X-rays when additional information about the bones or spinal alignment is required
- Evaluation of spinal stability and overall condition
- Review of previous spinal surgery, if applicable
Recovery After Unilateral Biportal Endoscopy
Recovery following UBE varies depending on the type of procedure performed and the patient’s overall health. Many patients can begin moving relatively soon after surgery, although activity restrictions may be advised during the initial recovery period.
Recovery may involve:
- Early mobilisation as advised by the treating team
- Appropriate pain management
- Gradual increase in daily activities
- Physiotherapy or rehabilitation when recommended
- Avoiding heavy lifting and strenuous activities during the healing period
- Follow-up consultations to assess recovery
- Gradual return to work and normal activities based on individual progress

FAQs
-
Is UBE the same as traditional open spine surgery?
No. UBE uses small portals and an endoscopic camera to access the spine, whereas traditional open surgery generally requires a larger incision and greater exposure of the surgical area. However, the appropriate approach depends on the specific spinal condition.
-
Which spinal conditions can be treated with UBE?
UBE can be used for selected cases of herniated discs, spinal stenosis, foraminal stenosis, and certain other conditions causing nerve compression. Its suitability depends on the patient’s anatomy, symptoms, imaging findings, and spinal stability.
-
Is Unilateral Biportal Endoscopy safe?
UBE is a surgical procedure and, like other forms of spine surgery, carries potential risks. These may include infection, bleeding, nerve injury, dural injury, recurrence of symptoms, or the need for additional treatment. A detailed assessment helps determine whether the potential benefits outweigh the risks for an individual patient.
-
Will UBE leave a large scar?
UBE uses small skin incisions rather than the larger incision generally associated with traditional open approaches. This usually results in smaller scars, although scar formation varies between individuals.
-
Can every patient with a slipped disc or spinal stenosis undergo UBE?
No. UBE is not suitable for every patient. Severe spinal instability, certain spinal deformities, extensive disease, or other anatomical and clinical factors may require a different surgical approach. The decision should be made after a detailed clinical and imaging assessment.
-
How do I know whether UBE is right for me?
A consultation with a spine specialist can help determine whether UBE is appropriate. Your symptoms, neurological examination, MRI or other imaging findings, spinal stability, previous treatments, and overall health are considered before recommending a surgical technique.
