Summary

Cervical discectomy using polymethylmethacrylate (PMMA) or titanium cages showed similar clinical outcomes and complications. Neither implant material offered a significant advantage, despite differences in surgical time and cost.

Area of Science:

Neurosurgery
Orthopedic Surgery
Spinal Surgery

Background:

Cervical disc protrusion and spondylosis are common spinal conditions requiring surgical intervention.
Ventral cervical discectomy is a standard surgical approach for addressing these pathologies.
Interbody fusion techniques aim to stabilize the cervical spine after disc removal.

Purpose of the Study:

To compare the clinical outcomes and complication rates of polymethylmethacrylate (PMMA) implants versus titanium cages for cervical interbody fusion.
To evaluate the efficacy and safety of two different implant materials in patients undergoing ventral cervical discectomy.

Main Methods:

A prospective study involving 200 patients with cervical disc protrusion or spondylosis.
Patients underwent ventral cervical discectomy at one or two levels.

Related Experiment Videos

100 patients received PMMA implants, while 100 patients received titanium cages for interbody fusion.

Clinical outcomes and complications were assessed post-surgery.

Main Results:

Both PMMA and titanium cage groups demonstrated similar complication rates.
Clinical outcomes were comparable between the two implant groups.
PMMA implant surgery was associated with longer operative times.
Titanium cages incurred higher material costs.

Conclusions:

There is no marked advantage of using PMMA implants over titanium cages, or vice versa, in terms of clinical outcomes and complications for cervical discectomy.
The choice of implant material may depend on factors beyond clinical efficacy, such as surgical efficiency and cost-effectiveness.
