The word means spondylo = spine, listhesis = to slip. It is slippage of a vertebra over the other.
This slip is seen in lower lumbar spine i.e. between L4-5, L5-S1, L3-4
But this listhesis can be seen so commonly in cervical spine (sometimes dorsal spine also) after major trauma.
There is weak connection between two vertebrae causing spine instability resulting in slip.
Symptoms are very similar to slip disc patients. Reason of back pain is abnormal movements due to spine instability. While the reason for leg pain is nerve pinch resulting from the slip.
Similar to slip / herniated disc, the diagnosis is always made by proper history (i.e. complains), checking by a spine specialist doctor and confirmed by MRI report. X-ray has great importance.
Similar to slip disc if problem is milder then conservative treatment is answer.
Surgical treatment of a spondylolisthesis may be recommended if patient has any one of these:
♦ Significant neurological deficit
♦ Severe pain affecting simple daily activities
♦ Failure of conservative modalities
♦ Significant muscle weakness
Any evidence of cauda equina syndrome
Surgery is standard and simple. It involves removal of nerve pinch – this helps in improving the leg pain. Also it involves stabilization of unstable spine by fixation with the help of a plates / rods and screws. This helps in complete relief and restoring normal functions later.
Not at all. This actually is so helpful that it immediately gives good relief; and moreover they are customized for use for stabilizing spine only, and not used for any place or part of the body. A second surgery for removal is not required as patient usually is so comfortable and does not have any pain or heaviness due to metal weight. After this surgery, patients are so comfortable that they can’t even know that they have plates and screws actually placed. A surgeon needs to tell them after surgery and actually prove it by showing on X- ray that metal implant is there.
Note: All other points about spondylolisthesis surgery are similar to slip / herniated disc (already explained above) i.e., after surgery pain, recovery, hospitalization period, restrictions, etc. The only major difference is that after the surgery patient in given a spine “belt” for 3 months which is mostly not required after disc surgery.
