3. Partial corpectomy, C5.
4. Machine bone allograft, C4-C5 and C5-C6.
5. Placement of anterior cervical plate with a Zephyr C4 to C6.
6. Fluoroscopic guidance.
7. Microscopic dissection.ANESTHESIA:
General.ESTIMATED BLOOD LOSS:
This is a patient who presents with progressive weakness in the left upper extremity as well as imbalance. He has also noted to have cord signal at the C4-C5 level secondary to a very large disc herniation that came behind the body at C5 as well and as well as a large disc herniation at C5-C6. Risks and benefits of the surgery including bleeding, infection, neurologic deficit, nonunion, progressive spondylosis, and lack of improvement were all discussed. He understood and wished to proceed.DESCRIPTION OF PROCEDURE:
The patient was brought to the operating room and placed in the supine position. Preoperative antibiotics were given. The patient was placed in the supine position with all pressure points noted and well padded. The patient was prepped and draped in standard fashion. An incision was made approximately above the level of the cricoid. Blunt dissection was used to expose the anterior portion of the spine with carotid moved laterally and trachea and esophagus moved medially. We then placed needle into the disc spaces and was found to be at C5-C6. Distracting pins were placed in the body of C4 and in to the body of C6. The disc was then completely removed at C4-C5. There was very significant compression of the cord. This was carefully removed to avoid any type of pressure on the cord. This was very severe and multiple free fragments were noted. This was taken down to the level of ligamentum. Both foramen were then also opened. Other free fragments were also found behind the body of C5, part of the body of C5 was taken down to assure that all of these were removed. The exact same procedure was done at C5-C6; however, if there were again free fragments noted, there was less not as severe compression at the C4-C5 area. Again part of the body at C5 was removed to make sure that there was no additional constriction. Both nerve roots were then widely decompressed. Machine bone allograft was placed into the C4-C5 as well as C5-C6 and then a Zephyr plate was placed in the body of C4 and to the body of C6 with a metal pin placed into the body at C5. Excellent purchase was obtained. Fluoroscopy showed good placement and meticulous hemostasis was obtained. Fascia was closed with 3-0 Vicryl, subcuticular 3-0 Dermabond for skin. The patient tolerated the procedure well and went to recovery in good condition.
