Beach Chair Position on an Operating Table: Setup and Safety for Shoulder Surgery

What the beach chair position requires from the table

In the beach chair position the back section is raised to a sitting angle, the legs are supported and slightly flexed, and the operative shoulder is left free beyond the edge of the table. The table therefore needs a back section with a wide range of motion, a leg section that can be lowered, and a top that can be shifted so the shoulder sits clear of the base.

Stability matters as much as range. A raised back section moves the patient's weight away from the column, so confirm the rated load in that position, not only the headline figure on the datasheet.

Lateral decubitus positioning, used for some arthroscopic approaches, asks for a different set of features: good lateral tilt, firm side supports and rails that accept traction devices. A table that handles both postures reduces the number of room changes in a busy shoulder list.

Selecting a shoulder surgery table

A shoulder surgery table should offer easy transitions between sitting, flat and lateral positions, memory positions that return the table to a known setting, and a low base that leaves room for the surgeon and for the C-arm if fluoroscopy is needed. The Lojer Smarter Practico offers a low base with 360-degree C-arm access, a quick memory function including height, and smart movements that recognise potential mechanical collisions and compensate automatically.

For patients with a higher body weight, consider a heavy-duty platform. The Lojer Grand Promerix has a safe working load of 275 kg and a slim base with improved C-arm access, which can simplify positioning in demanding cases.

Head support and the beach chair positioner

The head must remain in a neutral line with the spine throughout the case. A beach chair positioner or dedicated head support holds the head and neck securely while leaving the shoulder and upper chest free for draping and instruments. Check that the headrest attaches rigidly to the table rail and does not drift when the back section is raised.

Pad all pressure points, including the heels, sacrum and the contralateral arm. Use straps that hold the torso without compressing the chest, and check them again after every change of table angle.

• Neutral head and neck, no rotation or lateral flexion
• Shoulder clear of the table edge, with the scapula accessible
• Secure rail attachment for the headrest and arm positioner
• Padding at pressure points and straps rechecked after repositioning

Safety considerations for shoulder arthroscopy position

The shoulder arthroscopy position in a sitting posture is associated with haemodynamic changes, so the anaesthesia team normally monitors blood pressure with this in mind and follows the protocol of its institution. Positioning should be agreed in advance between surgeon and anaesthetist, and the table should make changes of angle smooth and controllable.

Ensure that the patient can be returned to a flat or Trendelenburg posture quickly in an emergency. Memory functions, an accessible hand control and a backup panel are practical features to check. Test battery operation and the floor lock before the first case of the day.

Room planning and next steps

Plan space for the arthroscopy tower, the fluid management equipment and the surgeon's stool, and confirm that the table can move far enough from the column to give imaging access. Read our operating table patient positions guide for a wider overview of postures.
