Answers
Answer:
Patient History
This 44-year-old female patient, previously a professional water skier, presents with 80% low back pain and 20% leg pain demonstrating a L5 distribution. Her symptoms have been severe for more than two years, but low back pain has been modest for more than 5 years.
Seven years ago she underwent a L5-S1 laminotomy / microdiscectomy with an excellent result.
Examination
She presents with isolated back pain over the L4-L5 and L5-S1 facet joints. Flexion is 60% of normal. Extension is limited to 20% of normal because of severe back pain. Straight leg raising tests are bilaterally negative. Strength is normal, but slightly diminished right to L5 light-touch sensation.
Prior Treatment
Although a L5 selective nerve root block provided short-term relief, there was no response to facet injections.L4-L5, L5-S1 degenerative disc disease, status post L5-S1 laminotomy / microdiscectomy
