Inverted-hook occipital clamp system in occipitocervical fixation. Technical note.

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Surgery

Background:

• Occipitocervical junction injuries present significant challenges.
• Current fixation methods may require prolonged immobilization or bone grafting.
• Instability at this junction necessitates effective surgical stabilization.

Purpose of the Study:

• To describe and evaluate a novel occipitocervical fixation technique.
• To assess the efficacy and safety of inverted occipital hooks for internal fixation.
• To determine if this technique can eliminate the need for posterior grafts and immobilization.

Main Methods:

• A retrospective review of fifteen patients undergoing occipitocervical fixation.
• Utilized inverted occipital hooks inserted via a burr hole in the occipital bone.
• Mean follow-up of 21 months (range 2-63 months).

Main Results:

• No implant failures were observed in the study cohort.
• Postoperative immobilization was not required for any patient.
• The procedure demonstrated successful internal fixation of the occipitocervical junction.

Conclusions:

• The described occipitocervical fixation technique using inverted occipital hooks is effective and safe.
• This method potentially obviates the need for posterior occipitocervical grafts.
• It offers a viable alternative for managing unstable occipitocervical junction lesions without external immobilization.
