6 DePuy Synthes Cervical Distractor Surgical Technique

The following handling instructions for the Synthes Cer-vical Distractor are intended for illustration of the basic functioning of these instruments. For further information about the surgical steps, please consult the respective surgical technique(s).

To insert the 2.7 mm Screws for Cervical Distractor (396.970 or 396.971), mount them on the self-holding, hexagonal Screwdriver for Cervical Distractor (396.967).

Should insertion prove difficult, pre-drill a hole for the screws using the 1.8 mm Cervical Drill Bit (396.968) mounted on the T-Handle with Quick Coupling (311.440).

Place the left Cervical Distractor (396.395) or right Cervical Distractor (396.396) over two of the 2.7 mm Screws (396.970 or 396.971). The distractor fits the screws loosely to facilitate placement and removal, and is not meant to lock on the screws.

Cervical Distractor Surgical Technique DePuy Synthes 7

To allow ease of placement of the cervical distractor over the screws for cervical distractor regardless of their ori-entation, ensure that the angle-setting tab (1, below) of the cervical distractor is initially unlocked.

Once positioned on the screws, push the angle-setting tab (1) (left) to the locked position (2, below) to ensure parallel distraction of the two screws.

Even with a locked angle-setting tab (2), the distractor still allows variable angulation in one plane to accommo-date different patient heights.

Achieve distraction between the two screws by turning the distraction tab (3) in a clockwise direction. The dis-traction can be adjusted by turning the distraction tab (3) counterclockwise, or released by pressing and hold-ing the release tab (4).

After removal of the cervical distractor, remove the screws using the selfholding hexagonal Screwdriver for Cervical Distractor (396.967).
