//Segmental Spinal Instability

What is?

We use the term spinal instability to describe the abnormal movement between to adjacent vertebrae. The primary symptom of this condition is axial pain which worsens during movements such as flexion, lifting weights, bending etc.

Instability after laminectomy

It is caused by the impairment of the elements of the spine: disc and/or ligaments degeneration. It can be also iatrogenic (for example back surgery).

The treatment is initially conservative, with short term bed rest, medication and physiotherapy. When the symptoms persist, surgery is indicated. The goal is to stabilize the spine and thus reduce or stop the abnormal spinal movements.
