Designed to mirror the normal mechanical

qualities of a natural disc, the sophisticated

M6-C artificial cervical disc and the

M6-L artificial lumbar disc incorporate

an artificial nucleus (made from

polycarbonate urethane)

and a woven fiber annulus

(made from polyethylene).

The M6 discs have been

biomechanically tested to

the equivalent of several

decades of vigorous use.

Artificial Disc Replacement


Artificial Disc Replacement

Thanks to the latest innovation in artificial disc replacement, London Bridge Hospital and Consultant

Orthopaedic Surgeon, Mr Khai Lam, are proud to offer a unique spinal surgical procedure using M6

prosthetic discs.

Together, the M6’s artificial nucleus and

annulus provide compressive capabilities

and a controlled range of natural motion.

This motion is designed to provide the

freedom for the patient to move their back

naturally, while minimising the stress to

adjacent discs and other important spinal

joints – potentially preventing or delaying

additional adjacent level degeneration. As

such, the M6 implant is the only prosthesis

in existence that offers restoration of the

natural qualitative motion equating to that

of the normal human intervertebral disc.

The M6 has two titanium outer plates

with keels for anchoring the disc into the

bone of the vertebral body. These outer

plates are coated with a titanium plasma

spray that promotes bone growth onto the

metal plates; providing long-term fixation

and stability of the disc into vertebral bone.


During cervical disc replacement surgery,

a small 3-4cm incision is prepared in

the front of the patient’s neck in

order to access the cervical spine.

During lumbar disc replacement

surgery, the patient will lie on

their back whilst surgeon Mr

Lam operates on the spine

through a similar small 4-5cm

‘minimal access’ incision

in the lower abdomen.

In both procedures, the

damaged disc is removed

(anterior discectomy), and the

bulging disc that is compressing

the nerve is then relieved via a

‘decompression’. The M6 disc is then

inserted into the disc space using

specialist precision instruments. After

the M6 is successfully placed, the

incision is closed. Patients are typically

discharged within two to three days

of the procedure as a result of the minimal


This life-changing procedure has seen

rapid recovery times, with some patients

returning to work the following week, and

to sports within a few months – something

which wouldn’t have been possible with

traditional treatment methods.

Mr Lam qualified from Nottingham

University and completed his spinal

surgery training at the Centre for

Spinal Surgery and Studies, Nottingham.

He completed his spinal fellowship

training after visiting a number of

renowned European spinal centres

of excellence.

Mr Khai Lam is a highly qualified,

practising spinal surgeon, and is

considered a key opinion leader

for spinal disc replacement surgery,

minimal anterior access surgery

(MASS), extra-lateral interbody fusion

(XLIF), Minimally Invasive Surgery

(MISS), revision spine surgery and

complex spinal deformities. Mr Lam

receives tertiary spinal referrals from

a regional population of 10 million

people. He continues to be a regular

visiting Professor to, and treats many

patients from, Saudi Arabia, Egypt,

UAE, Kuwait and Qatar.
