A new anterior cervical plating technique significantly reduced adjacent-level ossification development (ALOD). This method uses shorter plates and angled screws, decreasing ALOD incidence and severity compared to conventional methods.

Area of Science:

  • Spine surgery
  • Orthopedic implants
  • Biomechanical analysis

Background:

  • Proximity of anterior cervical plates (<5 mm) to adjacent disc spaces is a risk factor for adjacent-level ossification development (ALOD).
  • Anterior cervical plating offers advantages like higher fusion rates and improved alignment, necessitating technique modification to minimize complications.

Purpose of the Study:

  • To evaluate if a novel plating technique reduces the incidence of ALOD following anterior cervical plating.

Main Methods:

  • Retrospective matched cohort analysis of 100 patients comparing conventional (C) and new (N) plating techniques.
  • Patients were matched 1:1 based on age, gender, fusion levels, and comorbidities.
  • Radiographic analysis of lateral cervical spine X-rays at 6 months and 2 years post-surgery to measure plate-to-disc distances and ALOD incidence/severity.

Minimally Invasive Treatment for Thoracolumbar Burst Fracture Using Sagittal Alignment Screws and A Trauma Reduction Device

Published on: November 8, 2024

Main Results:

  • The new technique (Group N) achieved significantly greater mean plate-to-disc distances compared to the conventional technique (Group C) (p<.001).
  • Group N showed a significantly lower incidence of ALOD at cranial (42% vs. 72%) and caudal (20% vs. 42%) adjacent disc spaces (p<.05).
  • Severe ossification (Grade 2+) was less frequent in Group N (6% vs. 20%) (p<.05).

Conclusions:

  • The modified plating technique, utilizing shorter plates with longer, angled screws, effectively reduces the incidence and severity of ALOD.
  • This technique offers a promising solution to mitigate a known complication of anterior cervical plating.
