Back Surgery – Hemilaminectomy/Ventral Slot
Hemilaminectomy is a surgical procedure that we perform on a regular basis for canine patients at our hospital. It is useful for correcting slipped or herniated discs in the spine. If your dog is having difficulty walking or has pain or lameness, a compressed spine might be the culprit.
In this procedure, the articular facets (the joint surfaces between vertebrae) are removed and bulging disc material is cleared away from the spinal cord. If a disc in the neck has slipped, then the ventral slot procedure may be performed. These are advanced surgeries that are always performed by a neurosurgeon. The goal of surgery is to remove the disc material that has “slipped” and is pressing on the spinal cord and/or nerve root, which is causing pain and/or weakness. In general, a ventral slot procedure is done to remove a herniated disc in the neck and a hemilaminectomy is done to remove ruptured disc material in the back. Clinical Significance Ventral slot surgery can be used to achieve effective cervical spinal cord decompression with a good long-term outcome in the management of feline cervical intervertebral disc herniation. Ventral Slot This is the procedure employed when a disc is compressing a nerve root or an area of the cervical spinal cord. The procedure is done through an approach to the underside of the neck. This allows the surgeon to access the ventral or underside of the cervical vetebral bodies. A ventral slot is a partial corpectomy of two adjacent vertebral bodies and the corresponding intervertebral disc to gain access to the ventral spinal canal (Box 34-1). Ventral slots are performed in the cervical spine to treat centrally located intervertebral disc herniation.
Sometimes anti-inflammatories or other joint medication can resolve the discomfort, but if limited mobility and discomfort persist, the condition can be further assessed for alternative treatment options.
When additional diagnostics are needed, a CAT scan can be performed to determine if surgery is needed. The imaging can pinpoint the exact location of the slip or herniation, which is followed by surgery on the affected area to remove the obstruction.
Once the disc material is removed, regular movement of the spine is restored after periods of rest, recovery, and rehabilitation.

Ventral Slot Surgery Dog Recovery
Hello! My dog Mack (lhasa apso) had the ventral slot procedure done on his neck exactly 2 weeks ago. He had 2 ruptured discs that were causing him extreme pain. He had not lost function of his legs, but he was showing some nerve root pain by lifting up his left paw. They did surgery on him that night and he did great. We got to take him home the next night. We had some issues with him being extremely painful and yelping out in pain, we ended up having to take him back so he could get IV meds. He came home again the next day with a slew of meds, tramadol, methocarbamol, gabapentin, prednisone, and stuff to protect his stomach. I could tell a huge difference he was pretty much pain free for the most part. Still a little slow moving, especially in the morning, but over all a big improvement. He went back yesterday to have his stitches removed and the neuro did all sorts of tests moving his head all around. I was so afraid he was going to scream but he never did. We started decreasing his meds today. He is completely off the tramadol as well as methocarbamol. Those are only as needed. He is still taking the Gabapentin at 100mg every 8 to 12 hours, as well as his prednisone is cut down to 1/8 once a day. He did well yesterday evening, but this morning I had to take him to get his laser treatment, and when I got him out of the car he whined. The doctor told me it would be a very long recovery as far as the pain goes, because the neck is so sensitive. The main reason for this post is because I notice his neck twitching extremely hard. It almost makes his whole head bob sometimes. It was happening at his visit yesterday so I pointed it out to the neuro and he said that it might be something with his nerves, and he reminded me that they did have to go through muscle for the surgery so that spasms could be from that. I am SO worried that he has slipped another disc. I have been so strict with him, carrying him to the bathroom and he NEVER gets out of his cage, just to use the bathroom. But I have read where a dog can slip a disc just walking. I need to hear from someone whose dog has had cervical surgery and what the recovery was like. Is it normal for the dog to be in some pain 2 weeks out? Also do you think the twitching is just part of the healing? I can tell he is still in pain sometimes, especially when he is moving to go to the restroom. Is he just sore? I cant afford another surgery for him. This has already cost me 5 grand... I need some advice please!!! Thanks!
