Lumbar & Lumbosacral Spinal Instability

Lumbar instability occurs as a result of damage to one or more of the structures that make up the three columns of the spine. In some cases, this damage will lessen the ability of the stabilising structures to resist mechanical stress and potentially allow abnormal movement to occur at the intervertebral segment. With repeated trauma, mild low back pain may be replaced by severe episodes resulting in loss of function.

Clinical instability of the lumbar spine associated with fracture/dislocation is well recognised and usually requires surgical intervention. Spine surgeons, medical practitioners and physiotherapists have long realiszd that a less severe form of instability exists which can cause debilitating symptoms, while not displaying the dramatic neurological implications that are associated with fracture/dislocation.  This is often referred to as microinstability and mechanical back pain.

Patients with lumbar spine clinical instability have a history of recurring episodes of low back pain with loss of mobility. These episodes may occur several times per year. Patients have often been treated successfully with manipulation initially but may find as the condition progresses that any relief is only short-term.

In the acute phase, the pain is debilitating with the patient usually describing a severe catching pain in the lower lumbar spine. Generally all active movements are tentative and restricted by pain. Palpation of the affective segment will illicit pain if done quickly. If performed slowly and carefully, increased accessory movement may be detected.

The treatment of lumbar and lumbosacral instability depends upon the severity of symptoms, patient age, medical condition, and degree of deformity.  Surgery is generally reserved for more advanced forms and generally involves fusion of the affected vertebrae, and Dr. Aryan performs such surgery routinely using minimally invasive techniques.
