Case Report: Lumbar Disc Lesion with Altered Lordosis


In our last article, we presented the history of lumbar traction for normalization of the lumbar lordosis in chiropractic.  In this article, we will present a case report of a patient with a herniated lumbar intervertebral disc, who had been referred to us by a medical neurologist.

Case report

Figure 1A demonstrates the pre-treatment lateral lumbar radiograph of a 28-year-old female travel agent with low back pain and radiating right lower extremity pain secondary to a herniated disc at L4-L5. A line has been drawn across the posterior vertebral body margins of L1 through S1. A solid curved line representing the normal average lordosis derived from measurements taken from an ideal normal population without back pain or spinal pathology1-3 has been superimposed on the radiograph. These markings clearly indicate that, as compared to the normal average lumbar lordosis, this patient is hypolordotic with concurrent loss of disc space height at L4-L5.

Upon examination, the patient’s lumbar range of motion was mildly to moderately reduced in all directions. She had tenderness to digital pressure in the lumbosacral region, reported pain upon bilateral leg lowering in the supine position, and also experienced pain upon sitting up from a supine position. Straight leg raising was positive for the right lower extremity in both the supine and seated positions. All other orthopedic tests were negative, and her neurologic examination was unremarkable.

A program of structural based rehabilitation was initiated including lumbar extension exercises performed at a frequency of 10 repetitions per set and up to 10 sets per day.  Standing lumbar extension traction (Figure 3), as described in our last article, was performed on each office visit for up to 20 minutes per session. In addition, spinal adjustments for pain reduction and increased mobility were also performed at each office visit. The frequency of office visits was 5 times per week for the first 2 weeks, and 3 times per week for the remaining 6 weeks of care.  The patient reported 80-90 percent improvement in pain upon completion of the second week of treatment.

The rehabilitation program continued for the 6 additional weeks, whereupon a post-treatment radiograph of her lumbar spine was obtained. The normal average lordosis has once again been superimposed on the post-treatment radiograph as the solid curved line extending from the posterior-inferior vertebral body margin of S1. Comparison of the alignment of the posterior vertebral body margins of L1 through S1 to this normal average curve demonstrates a significant improvement. Functionally, her pain resolved, her range of motion normalized, and she was able to resume normal activities without restrictions.


Structural rehabilitation aimed at restoring more normal spinal alignment was demonstrated in this brief case report.  In addition to helping this patient achieve better spinal and postural alignment, she also achieved improved function in the form of pain reduction, enhanced range of motion, and improvement in her ability to perform her activities of daily living.  Upon discharge, she was given instructions to continue her lumbar extension exercises as a means of maintaining her improved structure and function.  This was achieved through the combination of spinal adjustments, active exercise, and lumbar extension traction.
