Summary

This summary is machine-generated.

Cervical disc arthroplasty (CDA) preserves motion, but changes in segmental mobility after surgery do not significantly impact clinical outcomes. Increased mobility may correlate with less heterotopic ossification (HO).

Keywords:

ACDF = anterior cervical discectomy and fusion CDA = cervical disc arthroplasty Cobb angle DDD = degenerative disc disease FDA = Food and Drug Administration HO = heterotopic ossification JOA = Japanese Orthopaedic Association NDI = Neck Disability Index ROM = range of motion VAS = visual analog scale cervical alignment cervical disc arthroplasty heterotopic ossification range of motion sagittal vertical axis segmental mobility

Background:

Cervical disc arthroplasty (CDA) is established for preserving motion post-discectomy.
Limited data exists on the extent of segmental mobility changes after CDA and their clinical relevance.
Understanding these changes is crucial for optimizing patient outcomes.

Purpose of the Study:

To evaluate changes in segmental range of motion (ROM) after 1-level CDA.
To investigate the correlation between these ROM changes and clinical outcomes.
To assess the relationship between segmental mobility, heterotopic ossification (HO), and clinical results.

Main Methods:

Retrospective review of 50 patients undergoing 1-level CDA.
Analysis of clinical outcomes: visual analog scale (VAS), Neck Disability Index (NDI), and Japanese Orthopaedic Association (JOA) scores.
Radiographic assessment of C2-7 Cobb angle, sagittal vertical axis (SVA), and segmental ROM (ΔROM) using CT scans; HO grading.

Main Results:

Significant improvement in all clinical outcomes (VAS, NDI, JOA) post-surgery.
No significant difference in mean segmental ROM (ΔROM) between pre- and post-operative states (-0.5° ± 6.13°).
Increased segmental mobility (ΔROM > 0°) was associated with lower incidence and severity of HO (p=0.048) and similar clinical outcomes compared to decreased mobility (ΔROM < 0°).
Lower segmental ROM correlated with higher HO grade (p=0.012), but ROM did not impact clinical outcomes.

Conclusions:

Segmental mobility and cervical alignment do not significantly impact clinical outcomes after 1-level CDA.
Increased segmental mobility post-CDA is linked to reduced HO and comparable clinical improvements.
Further research may explore the biomechanical implications of preserved or increased segmental mobility on long-term outcomes and HO development.
