Spinal meningeal cyst of the sacrum is uncommon congenital lesion. We experienced two cases of sacral meningeal cyst, so called Tarlov's cyst, who presented with radiating pain. Magnetic resonance imaging is a highly effective way of locating and approximating the size of these entities, which generally appear as intraspinal masses of low intensity on T1-weighted and high intensity on T2-weighted images, similar to cerebrospinal fluid(CSF). We evaluated 2 patients who had Tarlov's cyst diagnosed with conventional MRI. The clinical features, radiological findings, gross appearances of the lesion at surgery, surgical technique, histopathological features of the cyst wall, and surgical outcome are described. We conclude that excellent result can be expected in the case of symptomatic Tarlov's cyst by surgical decompression.

This study presents the cases of a 67-year-old female with an isolated left sacral fracture and a 69-year-old female with fractures in sacrum 1, 2, and the left pubic bone. Both patients exhibited marked improvement following integrative Korean medicine treatment, encompassing acupuncture, acupotomy, pharmacopuncture, herbal medicine, moxibustion, and cupping therapy. The treatment's efficacy was assessed using the numerical rating scale (NRS) scores, range of motion (ROM) in the lumbar spine, and alterations in gait and walking distance. Case 1 demonstrated an enhanced ROM and achieved independent walking after 29 days of treatment. Case 2 improved in both ROM and NRS score and could walk independently after 49 days of treatment. Significantly, radiological images showed notable changes in both cases following treatments. The study indicates that integrative Korean medicine treatment could provide clinical advantages to individuals suffering from sacral fractures.

Purpose: The purpose of this study is to determine the usefulness of arterial embolization on sacral and pelvic giant cell tumor (GCT). Materials and Methods: We retrospectively reviewed the medical records of 9 patients who had undergone serial arterial embolization between December 1996 and May 2008. We analyzed the clinical outcomes and therapeutic responsiveness of arterial embolization on sacral and pelvic GCT. Results: Six of 9 cases showed progression of disease (PD) status, even if 5 cases showed PD status despite of additional treatments including surgery and radiation, implying that serial arterial embolization on sacral and pelvic GCT is not effective. Three of 9 cases showed stable disease (SD) or continuous disease free (CDF) status and we analyzed associated factors with these good responses for embolization by ${\chi}^2$ test. The number of feeding vessels under six (p=0.048) and the number of collateral arterial supply under three (p=0.048) in the first angiogram showed significant relationships with good response for embolization, while remaining tumor staining by contrast after the first embolization and repeated embolization times were not significant. Conclusion: Although serial arterial embolization is not an effective modality on sacral and pelvic giant cell tumors, it may be a pilot modality under narrow indication of tumors with poor vascularity at first angiogram.

Objective : The purpose of this study is to evaluate neuroprotective effect of sacral neuromodulation in rat spinal cord injury (SCI) model in the histological and functional aspects. Methods : Twenty-one female Sprague Dawley rats were randomly divided into 3 groups : the normal control group (CTL, n=7), the SCI with sham stimulation group (SCI, n=7), and the SCI with electrical stimulation (SCI+ES, n=7). Spinal cord was injured by dropping an impactor from 25 mm height. Sacral nerve electrical stimulation was performed by the following protocol : pulse duration, 0.1 ms; frequency, 20 Hz; stimulation time, 30 minutes; and stimulation duration, 4 weeks. Both locomotor function and histological examination were evaluated as scheduled. Results : The number of anterior horn cell was $12.3{\pm}5.7$ cells/high power field (HPF) in the CTL group, $7.8{\pm}4.9$ cells/HPF in the SCI group, and $6.9{\pm}5.5$ cells/HPF in the SCI+ES group, respectively. Both the SCI and the SCI+ES groups showed severe loss of anterior horn cells and myelin fibers compared with the CTL group. Cavitation and demyelinization of the nerve fibers has no significant difference between the SCI group and the SCI+ES group. Cavitation of dorsal column was more evident in only two rats of SCI group than the SCI+ES group. The locomotor function of all rats improved over time but there was no significant difference at any point in time between the SCI and the SCI+ES group. Conclusion : In a rat thoracic spinal cord contusion model, we observed that sacral neuromodulation did not prevent SCI-induced myelin loss and apoptosis.

Objectives: We have evaluated the effects of conservative treatment on one patient who was diagnosed to thoraco-lumbar junction and lumbo-sacral junction transitional zone syndrome. so, we investigate thoraco-lumbar junction and Jumbo-sacral junction tranzitional zone syndrome that was suggested by Maigne R. Methods : One patient was diagnosed as T12-L1 herinated intervetebral disc through MRI. We diagnosed the patient to transitional zone syndrome by symptoms and physical examination and used Acupuncture therapy, Cox technique to the patient. We measured Visual Analog Scale(VAS) before and after treatment. Results: After treating Acupuncture therapy, Cox technique in the case, We find out that the patient was improved. VAS score changed from 7 to 2 and physical examinations are improved. Conclusions: We improved the patient who had thoraco-lumbar junction and lumbo-sacral junction transitional zone syndrome by Cox technique and Acupuncture therapy, and we found that thoraco-lumbar junction related lumbo-sacral junction.

Purpose: Gluteal perforator is easily identified in the gluteal region and gluteal perforator flap is a very versatile flap in sacral sore reconstruction. We obtained satisfying results using the gluteal perforator flap, so we report this clinical experiences with a review of the literature. Methods: Between November of 2003 and April 2006, the authors used 16 gluteal perforator flaps in 16 consecutive patients for coverage of sacral pressure sores. The mean age of the patients was 47.4 years (range, 14 to 78 years), and there were 9 male and 7 female patients. All flaps in the series were supplied by musculocutaneous arteries and its venae comitantes penetrating the gluteus maximus muscle and reaching the intrafascial and suprafascial planes, and the overlying skin forming a rich vascular plexus arising from gluteal muscles. Patients were followed up for a mean period of 11.5 months. Results: All flaps survived except one that had undergone total necrosis by patient's negligence. Wound dehiscence was observed in three patients and treated by secondary closure. There was no recurrence during the follow-up period. Conclusion: Gluteal perforator flaps allow safe and reliable options for coverage of sacral pressure sores with minimal donor site morbidity, and do not sacrifice the gluteus maximus muscle and rarely lead to post-operative complications. Freedom in flap design and easy-to perform make gluteal perforator flap an excellent choice for selected patients.

Study Design: Literature review. Objective: Ultrasound-guided injections are a common clinical treatment for lower lumbosacral pain that are usually performed before surgical treatment if conservative treatment fails. The aim of this article was to review ultrasound-guided injections in the lumbar and sacral spine. Summary of Literature Review: Ultrasound-guided injections, unlike conventional interventions using computed tomography or C-arm fluoroscopy, can be performed under simultaneous observation of muscles, ligaments, vessels, and nerves. Additionally, they have no radiation exposure and do not require a large space for the installation of equipment, so they are increasingly selected as an alternative method. Materials and Methods: We searched for and reviewed studies related to the use of ultrasound-guided injections in the lumbar and sacral spine. Results: In order to perform accurate ultrasound-guided injections, it is necessary to understand the patient's posture during the intervention, the relevant anatomy, and normal and abnormal ultrasonographic findings. Facet joint intra-articular injections, medial branch block, epidural block, selective nerve root block, and sacroiliac joint injections can be effectively performed under ultrasound guidance. Conclusions: Ultrasound-guided injections in the lumbar and sacral spine are an efficient method for treating lumbosacral pain.

The distribution of oviductal vessels of eight Korean native pheasants was observed after Latex casts of vessels. Latex was injected into thoracic aorta and posterior vena cava of these birds for cast preparation. The results were as follows: 1. The arteries suppling oviduct of the Korean native pheasants contained A. oviductalis cranialis, media, caudalis and vaginalis. The veins drainaging oviduct were stretched along the following ateries and all of the oviductal vessels were situated on the left side of the body. 2. The anterior oviductal artery arose from the pubic artery of the left external iliac artery and distributed to the infundibulum and the magnum of the oviduct. 3. The middle oviductal artery arose from the left sciatic artery and distributed to the isthmus and shell gland of the oviduct. 4. The caudal artery arose from the left internal pudendal artery of the median sacral artery and distributed to the caudal part of uterus and the cranial part of vagina. 5. The vaginal artery arose from the left internal pudendal artery of median sacral artery and distributed to the caudal part of vagina.

We present a rare case of fracture-dislocation at the level of the first sacral (S1) and second sacral (S2) vertebrae. The S1 was displaced forward into the pelvic cavity and was located just in front of the S2. Because the patient also had extensive neurological injury to the lumbar plexus and instability of the pelvic ring, surgery to stabilize the pelvis and to decompress the lumbar plexus was performed. The surgery was successful and the patient experienced marked improvement in neurological function.
