Histologically, Schmorl's nodes are defined as the loss of nuclear material through the cartilage plate, growth plate, and end plate into the vertebral body. Most Schmorl's nodes are asymptomatic, although there are some reports of symptomatic Schmorl's nodes, which should be treated similarly to vertebral compression fractures, with conservative treatment as the first choice. We report the case that we reduced the pain by blocking the ramus communicans nerve in a patient with Schmorl's node.

Objective : The aim of this study was to determine the efficacy of percutaneous radiofrequency neurotomy[RFN] of ramus communicans nerve in patients suffering from severe low back pain due to osteoporotic compression fracture. Methods : Twenty two patients with lumbar osteoporotic compression fracture who had intractable back pain for less than two weeks and were performed with RFN at L1-L4 from May 2004 to December 2005 were retrospectively analyzed. Clinical outcome using visual analogue scale[VAS] pain scores and modified MacNab's grade was tabulated. Complications related to the procedure were assessed. Results : Twenty-two female patients [age from 63 to 81 years old] were included in this study. The mean VAS score prior to RFN was 7.8, it improved to 2.6 within postoperative time of 48 hours, and the mean VAS score after 3 months was 2.8, which was significantly decreased. Eighteen of 22 patients were graded as excellent and good according to modified MacNab's criteria at final follow up. All patients recovered uneventfully, and the neurologic examination revealed no deficits. Two patients showing poor results worsened in symptom. Percutaneous was performed eventually resulting in symptom improvement. There were no significant complications related to the procedure such as sensory dysesthesia, numbness or permanent motor weakness. Conclusion : RFN is safe and effective in treating the painful osteoporotic compression fracture. in patients with intractable back pain due to lumbar osteoporotic compression fracture, RFN of gray ramus communicans nerve should be considered as a treatment option prior to vertebroplasty.

This study was carried out to investigate the branches and distribution of Nervus ophthalmicus of the Korean native goat. The observation was made by dissection of embalmed cadavers of ten Korean native goats. The results were as follows; 1. N. ophthalmicus arised from the trigeminal nerve in a common trunk with the maxillary nerve. 2. At the exit of the foramen orbitorotundum the N. ophthalmicus gave off Ramus zygomaticotemporalis, N. frontalis, Ramus sinuum frontalium and N. nasociliaris. 3. Ramus zygomaticotemporalis, after giving off N. lacrimalis, left the orbital cavity and gave off Rami cornuales which were distributed the caudolateral part of the base of the horn. 4. After giving off N. ciliaris longus and Ramus communicans cum ganglio ciliari, N. nasociliaris divided into N. ethmoidalis and N. infratrochlearis which gave off Rami cornuales.
