Multiple factors are involved in the pathogenesis of postoperative back pain and include type and duration of surgery, duration of immobilisation, and the position of the patient during spinal puncture. Diagnosis of back pain is not simple; contributing factors may include needle trauma, surgical positioning and injection of saline or local anaesthetic into the interspinous ligaments, development of a supraspinous haematoma, excessive stretching of ligaments after relaxation of paraspinal muscles and localised trauma to the intervertebral disc.

We accessed four databases (the American Academy of Neurology, The Cochrane Library, PubMed, CINAHL) and used several search strings: "spinal puncture, post lumbar, dural, postdural, puncture, needle"; "headache, back pain, backache"; "bed rest, posture, immobilization, early ambulation"; and "caffeine/therapeutic use."
