Degenera�ve disc disease Surgical technique 1. Pa�ent posi�oning and approach The pa�ent is placed in the supine posi�on with the head in slight extension. The posterior cervical spine is supported to establish and maintain normal cervical lordosis. The surgeon must then choose a right or le� sided approach to the cervical column. A�er exposing the cervical spine, the self retaining retractor is placed to provide op�mal visualiza�on. A vertebral body distractor (1507003900) may be used. The distrac�on sha�s (1507000400) are posi�oned midline in the vertebral bodies adjacent to the level to be...

3. Adjus�ng plate curvature WALEN Anterior Cervical Plate is provided with a pre-machined lordo�c curve. If required, the plate may be contoured to increase the amount of lordo�c curvature or decrease the amount of lordo�c curvature by using the Plate Bender (1503201300). A gradual bend should be made over the en�re length of the plate and abrupt changes in curvature should be avoided. Increase Lordosis Decrease Lordosis 4. Placing temporary fixa�on pins A�er selec�ng the appropriate plate, use the Temporary Fixa�on Pins (1503201900) to hold the plate in place while drilling and placing the screws....

6. Drilling holes Screw angle may be selected and the plate stabilized during the drilling procedure. The Plate Holder/ Drill Guide (1503200700) may be a�ached to the plate by placing the expandable end into a lateral screw hole and turning the knurled knob clockwise. 7. Selec�ng and using drill bits The WALEN Anterior Cervical Pla�ng System offers the ability to select various angles of screw placement to conform to individual pa�ent anatomy. Some certain angles may direct the screws at vulnerable vascular and neural �ssues. Use fluoroscopy to confirm drill bit penetra�on depth and angular orienta�on...

9. Inser�ng screws Select the appropriate screw length corresponding to the hole drilled. Using the Hex Driver (1503201600), pick the screw from the tray and insert it through the plate. Drill the first hole, tap if desired, and place the screw without �ghtening completely. A�er confirming proper plate posi�on, drill, tap if desired and place screw in all remaining screw holes. Begin with the lateral hole that is opposite and diagonal to the first prepared hole. Remove Temporary Fixa�on Pins and perform final �ghtening of all screws in the same sequence as men�oned above. 10. Locking the cams Locking...

Neulen Cervical Laminoplasty System Advantage In the posterior cervical open-door opera�on, it can achieve real-�me lamina support func�on, and maximum maintain spinal canal enlarging state in laminoplasty The support piece specially designed on the underpart pf plate, can play a role of strong suppor�ng before screws be fixed, and reduce the force on screws. The plate opening is arc shaped, which can maximize accept the lamina broken end, making it more stable. The board has certain plas�city, can be fixed a�er bending according to special s

Mul�segmental OPLL Cervical spinal stenosis Mul�level cervical myelopathy Surgical technique 1. Pa�ent posi�oning The pa�ent is posi�oned prone as for most other posterior cervical procedures, with the head secured in a Mayfield three-pin head-holder, preferably in slight flexion (Figures 1 and 1a). Some cervical flexion helps reduce the overlap of the laminae and facet joints, which facilitates the laminoplasty itself. A reverse Trendelenberg posi�on may help decrease bleeding from epidural and paravertebral veins.

Note: In the event that the posterior decompression ought to extend to the C2 level, this can be accomplished while respec�ng the integrity of the C2 posterior arch and the majority of its muscular origins and inser�ons. A so-called dome laminectomy is performed by using a burr and kerrison to remove the lower margin of C2, followed by the cancellous bone and ventral cortex (Figures 4, 4a and 4b). 2. Surgical exposure The surgeon performs a midline posterior exposure from the inferior aspect of C2 to the superior aspect of T1 (Figures 2 and 3). The lateral dissec�on follows the subperiosteal...

Note: The side of the spinal canal to be opened may be chosen for a number of reasons. If supplemental foraminotomies are planned, then the open side should be ipsilateral to them. If the pa�ent’s myelopathy is asymmetric, some surgeons prefer to open the more involved side. Finally, all things being equal, the choice may be influenced by the surgeon’s dominant hand. A right hand dominant surgeon will probably wish to stand on the pa�ent’s le� and open the le� side. The converse would be the case for a le�-handed surgeon. 3. Open side trough prepara�on The open side trough is prepared with a burr...
