We describe a case of sacral perineural cyst presenting with complaints of low back pain with neurological claudication. The patient was treated by laminectomy and excision of the cyst. ⋯ Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints.

Randomized Controlled Trial Multicenter Study
German Acupuncture Trials (GERAC) for chronic low back pain: randomized, multicenter, blinded, parallel-group trial with 3 groups.
To our knowledge, verum acupuncture has never been directly compared with sham acupuncture and guideline-based conventional therapy in patients with chronic low back pain. ⋯ Low back pain improved after acupuncture treatment for at least 6 months. Effectiveness of acupuncture, either verum or sham, was almost twice that of conventional therapy.

Comparative Study
Posterior lumbar interbody fusion versus posterolateral fusion in adult isthmic spondylolisthesis.
A prospective study with historical controls. ⋯ Type of fusion, PLIF or PLF, does not affect the 2-year outcome of surgical treatment of adult isthmic spondylolisthesis. Despite the theoretical advantages of PLIF, no improvement on patient outcome compared with posterolateral fusion could be demonstrated, questioning the need of anterior support in short lumbar fusions.
