The Lumbar Prosthesis
LP-ESP
The LP-ESP lumbar disc prosthesis has been developped to mimic the natural lumbar disc and allow the spine to behave as if the replaced disc would be natural in all situations.
HKD$8,000
HKD$6,800
Specifics
- Over 10 years of research and development
- 10 years of follow up (since 2004)
- 6° of freedom
- Adaptive center of rotation
- No surface bearing for an increased lifetime
- Improved stability
- shock absorbing
- Designed to fit and restore patient lordosis
How the LP-ESP prosthesis has been engineered
Structure of the natural lumbar disc
- Inner core (nucleus pulposus)
- Outer core (annulus fibrosis)
Structure of the LP-ESP® lumbar prosthesis
- Titanium endplates TA 6V ISO 583213 and hydroxyapatite coating
- Inner core (Silicone nucleus)
- Outer core (Polycarbonate urethane annulus)
Six degrees of freedom restore your “natural” mobility.
- Lateral flexion
- Vertical translation
- Lateral translation
- Flexion/extension
- Anterior-posterior translation
- Axial rotation
Indications for use
- Lumbar discopathy that is resistant to medical treatment
- Lumbar discopathy disease after treatment of a herniated disc
- Radiculopathy due to a recurrenced of a disc hernia (except for excluded hernias sequestered herniated disc)

Surgical procedure
The procedure is performed under general anesthesia. An x-ray is taken in order to precisely determine and mark the vertebral level of surgery and the site for accessing the lumbar spine. A midline (transperitoneal or retroperitoneal) approach is used to access the site.
Once the site has been accessed, the affected disc is removed and the disc compartment is prepared for the implantation of the LP-ESP®. The correct level of the spine is determined and then the implant is inserted.
Once the LP-ESP® has been implanted, another x-ray is performed in order to ensure that the prosthesis is seated properly and is at the right level in the disc compartment. The wound is then closed and after a short recovery period, you can start to resume your regular activities and return to your everyday routine.
Recovery and a relaxed life after the procedure.
