A Clinico-Radiological correlation of patients with Lumbar spinal instability
Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 5
Abstract
Background: According to the American Academy of Orthopaedic Surgeons, instability was defined as an abnormal response to applied loads, characterized by movement in the motion segment beyond normal constraints in 1989. Material and methods: This was an observation study in which patients of age group 30-70 of which 11 male and 19 females with history suggestive of lumbar spinal instability with other condition were evaluated clinically and radiologically from December 2006 to September 2008 with clinical tests and with static and dynamic X-rays. Chi-square test was used. Results: In our study we have found that the majority of the patients were in the age group of 51-60 yrs. i.e. 36.7% followed by 41-50 yrs. i.e. 33.3%. The majority of the patients were Female i.e. 63.3% followed by Male 36.7%. Neurodeficit was present in 73.3% persons and absent 29.7% . The most common level of instability was at L5-S1 i.e. 70.00% followed by 10.0% at L4-L5 and at L4-L5&L5-S1 in 10.0% respectively. Increase lordosis was present in 66.6% followed by Decrease lordosis in 20.0% and Scoliosis was present in 13.3% PLE (passive Lumbar Extension Test) was positive in 83.3 % and was absent in 16.7% patients. Sagittal translation instability was present in 66.7 % patients Angular instability was present in 10.00% patients, Rotational Instability was present in 16.7% of the patients, Coronal translation instability found in 3.3% Patients, clinical instability was present in 93.3% of the Patients Radiological instability was present in 76.7% of the patients. No any significant difference seen in Clinico- Radiological instability (χ2=0.652, P>0.05-Not significant). Conclusion: Degenerative spinal instability was more common in females and more common in age group of 50-60 yrs. most common type of instability is sagittal translational instability and statically there was no difference in Radiological and clinical diagnosis so there was good correlation.
