Lumbo-Sacral Distraction Fusion

Over recent years, we have developed an innovative operation for treatment of patients with lumbo-sacral disease where compression of the nerve roots supplying the back legs is present, and particularly where instability between the vertebrae is suspected. This technique involves distraction (stretching) of the lumbo-sacral joint by placing a specially-designed titanium bolt between the vertebrae, and providing additional stability using both pins and bone cement.

This combined treatment immediately relieves the compression on the nerves, and allows the lumbo-sacral joint to fuse preventing further long-term problems from developing. We are currently the only veterinary centre worldwide routinely offering this technology.

Most patients are able to walk by the day after surgery, and are more comfortable than before the surgery within a few days. However, if the nerves have been severely damaged or compressed for a long period of time, some dogs can take several months to achieve their best possible outcome. Postoperative care is particularly important to avoid complications and to allow full rehabilitation after surgery, and our on-site physiotherapy and hydrotherapy teams are frequently involved with post-operative management of patients undergoing this type of treatment.

 Spinal Surgery Unique to Fitzpatrick Referrals

We have developed an innovative distraction fusion system which can be used in conjunction with either pins and cement or locking plates such as SOP™, to alleviate pain and resolve dysfunction associated with degenerative intervertebral disc disease.
