Postoperative Management Protocol for Incidental Dural Tears During Degenerative Lumbar Spine Surgery: A Review of 3,183 Consecutive Degenerative Lumbar Cases Abstract. Study Design: Retrospective review. Objectives: To review the experience of a single institution with degenerative lumbar surgery and to identify cases of incidental dural tears (DTs); and to report on the efficacy of our postoperative management protocol for DT, which relies on early mobilization.ethods: A total of 3,183 degenerative lumbar spine cases (decompression and/or fusion) were reviewed. Cases complicated by an incidental DT were identified. Patients who required a return to the operating room for a second procedure were identified and the operative findings were reviewed.

Rare birth: Baby born completely encased in amniotic sac What is 'en caul'. The amniotic sac is an opaque bubble that covers all babies in the womb from right after conception. As the baby grows, it fills with fluid, including the baby's urine. The sac cushions the baby from bumps and jostles during mom's daily ups and downs. Normally, during a birth, it breaks, and the fluid rushes out, which is where the term 'breaking water' comes from. But sometimes, the sac can get stuck around part of the baby, according to Dr. Amos Grunebaum, an obstetrician and gynecologist, who publishes a website on birth and baby care.

Lamina dura Lamina dura is bundle bone that lies adjacent to the periodontal ligament, lining the tooth socket. The lamina dura surrounds the tooth socket and provides the attachment surface with which the Sharpey's fibers of the periodontal ligament perforate. On an x-ray a lamina dura will appear as a radiopaque line surrounding the tooth root. An intact lamina dura is seen as a sign of healthy periodontium. Lamina dura, along with the periodontal ligament, plays an important role in bone remodeling and thus in orthodontic tooth movement.
