Single-door cervical laminoplasty using titanium miniplates alone.

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Surgery

Background:

• Cervical myelopathy requires surgical decompression to prevent neurological decline.
• Cervical laminoplasty is a common surgical approach for posterior decompression.
• Titanium miniplates offer a potential fixation method for laminoplasty procedures.

Purpose of the Study:

• To evaluate the outcomes of single-door cervical laminoplasty using only titanium miniplates for cervical myelopathy.
• To assess the safety, efficacy, and complications associated with this surgical technique.

Main Methods:

• Retrospective review of 29 patients with cervical myelopathy undergoing single-door laminoplasty.
• Utilized titanium miniplates for lamina fixation, with variations in plate type and fixation strategy.
• No bone graft or spacer was used; unicortical screw fixation was common.

Main Results:

• Significant improvement in Japanese Orthopaedic Association (JOA) scores at one-year follow-up (mean increase from 9.2 to 13.2).
• Mean JOA recovery rate of 64% with no neurological deterioration observed.
• Achieved substantial canal expansion (mean increase of 5.3-6.1 mm) with a high hinge union rate.

Conclusions:

• Single-door cervical laminoplasty with titanium miniplates alone is a safe and effective surgical option.
• The technique provides good spinal canal expansion and promotes neurological recovery in patients with cervical myelopathy.
• Low rates of serious complications were noted, including transient C5 palsy and one delayed dural tear.
