C-Arm for Surgery: Choosing the Right Machine by Procedure

How a C-arm is used in the operating room

During surgery the C-arm provides live fluoroscopy and still images on a monitor so the team can see instruments, implants and anatomy without opening more tissue. It is brought to the table at the moment it is needed, then parked away from the sterile field. Typical workflow: position the patient, drape the arm, take a few images to confirm position, and repeat during critical steps.

Image quality, stable positioning and fast image transfer determine how smoothly this works. Features such as position memory and a laser localiser reduce repeated exposures. For an introduction to the basic machine, see what is a C-arm machine.

Orthopaedics and trauma

This is the largest user group. Surgeons check fracture reduction, guide wires, intramedullary nails, screws and plates, and confirm length and rotation. A C-arm with a flat panel gives clear visibility of metal and bone, and long-bone stitching software helps in limb alignment. A compact base and large working space under the arm are important in crowded trauma theatres.

See C-arm in orthopaedic surgery for details. Models like the Arcovis DRF with 21 × 21 or 30 × 30 cm detectors and generator options from 5 to 25 kW suit this work.

Spine, urology and pain management

Spine procedures need reliable lateral and AP views for level confirmation and for pedicle screw placement, and higher-end systems add 3D. Urology uses the C-arm for stone localisation, stent placement and retrograde studies; an intensifier-based or compact flat-panel machine often meets this need. Pain management relies on precise needle guidance, where laser positioning and low-dose pulsed modes are valued.

Vascular and general surgery

Vascular and hybrid work requires digital subtraction angiography, road mapping, strong generator power and good heat capacity so fluoroscopy can continue through long cases. The PLX C7100 offers a 12 inch dynamic flat panel, generator output up to 25 kW, DSA and an injector interface. General surgery uses the C-arm for cholangiography and tube or line placement, usually with modest requirements.

Match the generator and software to the most demanding procedure on your list, not the average case.

• Orthopaedics and trauma: flat panel, stitching, compact base
• Spine: 3D option, clear lateral views
• Urology: simple, robust, easy to position
• Vascular: DSA, roadmap, high heat capacity
• Pain: laser positioning, pulsed low-dose modes

Room, power and workflow

Check door width and floor loading, outlets close to the table, space for the monitor cart so the surgeon can see the screen, and a parking position outside the sterile field. Plan cable routes to avoid trip hazards and decide where the radiographer will stand. Lead protection should be available for everyone in the room.

Decide in advance who is authorised to operate the unit, how images are stored and sent to PACS and how the unit is cleaned between cases.

Think about scheduling too: if one C-arm serves several theatres, define a booking routine and a parking spot that keeps it out of corridors, because a machine that is hard to find or reach tends to be skipped when time is short. Biomedical engineers should add the unit to the preventive maintenance schedule from day one.

Choosing and buying

Collect a list of procedures with volume per week, rank the most demanding, then match detector size, generator power and software. Ask suppliers for installation, operator training and local service terms. Registration of the device with the relevant UAE authority and facility licensing (DHA, DOH or MOHAP depending on the emirate) should be confirmed before purchase.
