Surgical Technique for TDR/ACDF Hybrid Constructs: A Surgical Video Case Example.

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spine Surgery

Background:

• Anterior cervical discectomy and fusion (ACDF) is standard for cervical spine issues.
• Total disc replacement (TDR) offers motion preservation and may reduce adjacent segment disease (ASD).
• Contiguous hybrid constructs (ACDF + TDR) are established, but non-contiguous approaches lack extensive literature.

Observation:

• A technique report details a 59-year-old male with non-contiguous cervical spondylosis.
• The patient underwent a successful C2/C3 ACDF and C4/C5, C5/C6 TDR via an anterior hybrid approach.
• The procedure involved unique technical considerations for exposure and discectomy at non-contiguous levels.

Findings:

• The non-contiguous hybrid anterior fusion and disc arthroplasty was performed without complications.
• The patient was discharged on postoperative day 1 with satisfactory motion preservation and clinical outcomes.
• This case demonstrates the feasibility of non-contiguous hybrid constructs in managing multi-level cervical spondylosis.

Implications:

• This technique offers a viable motion-preserving surgical option for specific multi-level cervical spondylosis cases.
• Further research into non-contiguous hybrid constructs may expand treatment possibilities for cervical spine pathology.
• The presented technique guide and case study contribute to the understanding of complex anterior cervical spine surgery.
