Skull Clamp for Cervical Surgery: Head Fixation on Open-Frame Tables

Why head fixation matters in cervical spine surgery

In posterior cervical procedures the patient is usually prone, and the head must hold a neutral, stable position for the length of the case. Even small movements transmit to the cervical spine, can affect alignment, and may interfere with navigation or intra-operative imaging. Rigid pin fixation also keeps the face free of pressure, which is a significant advantage over foam headrests in prone cases.

Cervical spine surgery positioning is a shared responsibility between the surgeon, anaesthetist and nursing team. The head is normally fixed after intubation and before final prone positioning, then the whole patient is turned or transferred in a controlled manner. Agree the roles before the case, and note the neck angle and clamp settings in the record.

Open-frame tables and clamp design

Spinal frames such as open-frame tables hold the torso on padded supports and leave the abdomen free. A cranial clamp designed for flat table tops may not fit between the rails, and an unsuitable clamp can force the head too high or too far from the neck line. The clamp therefore needs a shape that lets the head lower into the frame.

The DORO for Spine skull clamp is designed for open-frame OR tables. Its shape allows the patient's head to be lowered between the rails of the frame, giving more freedom in positioning. It is metal-free, which permits CT and angiography imaging, and table adaptors let it fit a wide range of OR tables.

Mayfield head holder for cervical spine: what to compare

Surgeons often say Mayfield head holder cervical spine when they mean any three-pin clamp used on a frame. When comparing options, check how far the head can be lowered, whether the clamp is radiolucent for lateral fluoroscopy, how the table adaptor attaches, and whether the clamp interferes with the C-arm path or the surgeon's working position.

A skull clamp for spinal fusion should not obstruct lateral views of the cervical spine. Radiolucent construction helps the team confirm hardware placement without moving the patient. For the broader types of clamp see skull clamp types.

• Head can be lowered into the frame
• Metal-free body for fluoroscopy, CT or angiography
• Table adaptor for your frame and OR table
• Pin set suitable for adult bone and, where relevant, paediatric patients
• Cleaning and reprocessing compatible with your department

Safety during prone cervical cases

Check the eyes, nose and ears after final positioning, make sure the airway is secure and the tube is accessible, and confirm that neuromonitoring electrodes and cables are not under pressure points. Re-check pin sites if the table is tilted or reversed. A pin that was well seated in the supine position can behave differently after the table moves.

Because pin fixation is a clinical decision, review the specific risks in skull clamp safety and complications and the general principles in prone position for spine surgery.

Specifying a system for your spine theatre

List your frame models and OR tables, the imaging you use, and whether you also operate on children. Ask for table adaptors to be quoted with the clamp, and request the instructions for use and cleaning documentation.

Ask the supplier for a short written statement of the positions and table types for which the clamp has been validated. A one-page confirmation of the table and frame models in your theatre prevents surprises at installation.
