Intervertebral bone implants following excision of protruded lumbar discs

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Surgery

Background:

• Intervertebral lumbar disc protrusions are a common cause of back and leg pain.
• Surgical intervention is often required for persistent symptoms.
• The use of autologous bone grafts in spinal procedures is a well-established practice.

Purpose of the Study:

• To evaluate the efficacy and outcomes of a surgical technique involving the implantation of lamina bone into the intervertebral disc space after disc excision.
• To assess patient satisfaction and functional recovery following this specific surgical approach.

Main Methods:

• A retrospective analysis of 456 consecutive cases undergoing the described surgical technique for lumbar disc protrusion.
• Patient follow-up ranged from 1 to 10 years.
• Outcomes were assessed based on return to normal activities, patient satisfaction, and need for further treatment.

Main Results:

• Of 418 patients followed, 92% reported a return to normal activities and expressed satisfaction with the surgical outcome.
• Thirty percent of patients experienced recurrent episodes of back or leg pain requiring conservative management.
• Ten patients required subsequent back surgery, with only one instance of implant dislocation.

Conclusions:

• The lamina implantation technique following lumbar disc excision demonstrates a high success rate in terms of patient satisfaction and functional recovery.
• While effective, a notable percentage of patients may require further conservative treatment for recurrent pain.
• The technique appears safe, with a very low rate of implant-related complications.
