Abstract

Insights

Delayed infection and hydroxyapatite (HA) spacer dislodgement after laminoplasty can cause cervical myelopathy. Prompt surgical debridement, spacer removal, and antibiotics effectively treat this rare complication.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Infectious Diseases

Background:

  • Cervical myelopathy can result from delayed complications following spinal surgery.
  • Laminoplasty, a procedure to decompress the cervical spine, may utilize implants like hydroxyapatite (HA) spacers.
  • Delayed infections and implant dislodgement are potential, though uncommon, risks associated with spinal fusion materials.

Purpose of the Study:

  • To report a rare case of delayed infection and hydroxyapatite (HA) spacer dislodgement after cervical laminoplasty.
  • To highlight the clinical presentation and diagnostic findings of this complication.
  • To emphasize the effective management strategy for this specific post-operative issue.

Main Methods:

  • A 73-year-old male patient with progressive cervical myelopathy was evaluated.
  • Magnetic resonance imaging (MRI) identified a delayed infection and dislodged HA spacers at the C3-C6 laminoplasty site.
  • Surgical debridement, removal of HA spacers, and targeted antibiotic therapy were performed.

Main Results:

  • The patient presented with symptoms of cervical myelopathy 16 years after C3-C6 double-door laminoplasty with HA spacers.
  • Diagnostic imaging confirmed a delayed infection and dislodgement of the HA spacers.
  • Post-operative treatment with surgical debridement and antibiotics led to resolution of symptoms.

Conclusions:

  • Delayed infection and HA spacer dislodgement following laminoplasty is a rare cause of progressive cervical myelopathy.
  • Timely diagnosis and comprehensive treatment, including surgical debridement, complete spacer removal, and appropriate antibiotics, are crucial for effective management.
