Abstract
OBJECT Superior cluneal nerve (SCN) entrapment neuropathy is a poorly understood clinical entity that can produce low-back pain. The authors report a less-invasive surgical treatment for SCN entrapment neuropathy that can be performed with local anesthesia. METHODS From November 2010 through November 2011, the authors performed surgery in 34 patients (age range 18-83 years; mean 64 years) with SCN entrapment neuropathy. The entrapment was unilateral in 13 patients and bilateral in 21. The mean postoperative follow-up period was 10 months (range 6-18 months). After the site was blocked with local anesthesia, the thoracolumbar fascia of the orifice was dissected with microscissors in a distal-to-rostral direction along the SCN to release the entrapped nerve. RESULTS were evaluated according to Japanese Orthopaedic Association (JOA) and Roland-Morris Disability Questionnaire (RMDQ) scores. Results In all 34 patients, the SCN penetrated the orifice of the thoracolumbar fascia and could be released by dissection of the fascia. There were no intraoperative surgery-related complications. For all patients, surgery was effective; JOA and RMDQ scores indicated significant improvement (p < 0.05). CONCLUSIONS For patients with low-back pain, SCN entrapment neuropathy must be considered as a causative factor. Treatment by less-invasive surgery, with local anesthesia, yielded excellent clinical outcomes.

Abstract
The genus Citrus includes mandarin, orange, lemon, grapefruit and lime, which have high economic and nutritional value. The family Rutaceae can be divided into 7 subfamilies, including Aurantioideae. The genus Citrus belongs to the subfamily Aurantioideae. In this study, we sequenced the chloroplast matK genes of 135 accessions from 22 genera of Aurantioideae and analyzed them phylogenetically. Our study includes many accessions that have not been examined in other studies. The subfamily Aurantioideae has been classified into 2 tribes, Clauseneae and Citreae, and our current molecular analysis clearly discriminate Citreae from Clauseneae by using only 1 chloroplast DNA sequence. Our study confirms previous observations on the molecular phylogeny of Aurantioideae in many aspects. However, we have provided novel information on these genetic relationships. For example, inconsistent with the previous observation, and consistent with our preliminary study using the chloroplast rbcL genes, our analysis showed that Feroniella oblata is not nested in Citrus species and is closely related with Feronia limonia. Furthermore, we have shown that Murraya paniculata is similar to Merrillia caloxylon and is dissimilar to Murraya koenigii. We found that "true citrus fruit trees" could be divided into 2 subclusters. One subcluster included Citrus, Fortunella, and Poncirus, while the other cluster included Microcitrus and Eremocitrus. Compared to previous studies, our current study is the most extensive phylogenetic study of Citrus species since it includes 93 accessions. The results indicate that Citrus species can be classified into 3 clusters: a citron cluster, a pummelo cluster, and a mandarin cluster. Although most mandarin accessions belonged to the mandarin cluster, we found some exceptions. We also obtained the information on the genetic background of various species of acid citrus grown in Japan. Because the genus Citrus contains many important accessions, we have comprehensively discussed the classification of this genus.

Abstract
OBJECTIVE Cervical anterior fusion with autologous bone grafts (Williams-Isu method) is a modified, accepted method to treat spinal degenerative disease. Here we report minimum 10-year outcomes. METHODS Of 101 patients we treated by cervical anterior fusion using the Williams-Isu method, 50 patients were followed up for a mean of 177 months. Among the 51 patients lost to long-term follow-up 12 were contacted by telephone; they reported their condition as good and none required reoperation. We evaluated their clinical outcomes on the Japan Orthopedic Association (JOA) score and assessed radiologic findings. RESULTS The average JOA score was 12.5 preoperatively, 15.9 at 2 years after surgery (recovery rate 74.9%), and 15.5 at final follow-up (recovery rate 67.0%). All 5 reoperated patients were treated on the level adjacent to the original lesion. Radiographically, cervical alignment changed from 12.5° to 9.0°, the fused segment angle changed from 5.4° to -0.6°. Although worsening of the fused segment angle did not affect the clinical results, it did affect postoperative cervical sagittal alignment. Cervical alignment and range of motion (ROM) were not different between reoperated (group I) and nonreoperated patients (group II). Fused segment angle worsening was milder than expected in group I. CONCLUSIONS The long-term results after the Williams-Isu method were good. The fused segment angle loss of approximately 6° did not affect long-term outcomes although it did affect sagittal cervical alignment. Postoperative worsening of the fused segment angle and hyper ROM changes in the adjacent level were not related to the need for reoperation in our study.

Abstract
Hydrogen-sorption isotherms of alkali metal-doped carbons at 77 K were determined for promoting application of these materials as hydrogen-recovery and isotope-separation agent. The hydrogen-sorption behavior of rubidium-doped Grafoil, with composition of RbC24, showed high sorption ability against hydrogen at low pressure. Taking into account the fact that sorption-desorption was fast and reversible, and the equilibrium pressure at half coverage was very low, i.e., 40 Pa, RbC24 prepared from Grafoil is promising as a recovery agent for hydrogen gas at low pressure. The hydrogen (H2)/deuterium(D2)-sorption isotherms of potassium-doped carbons with composition of KC10, prepared from multi wall carbon nanotube (MWCNT) and carbons derived from petroleum cokes with heat-treatment temperatures of 1000 and 1500 degrees C, were also determined. Isotope separation coefficient was estimated from those isotherms. A very large isotope effect was found for KC10 prepared from MWCNT, comparable to those prepared from carbons with heat-treatment temperatures of 1000 or 1500 degrees C. However, a severe problem was found for KC10 (MWCNT) that repetition of the sorption-desorption cycles resulted in the decrease of the sorbed amount of H2 and D2.

Abstract
A 25-year-old woman and a 31-year-old man presented with chronic lower back pain and unexplained lower abdominal pain. Both patients had groin tenderness at the medial border of the anterior superior iliac spine. The results of radiographical and physical examinations suggested sacroiliac joint dysfunction. Sacroiliac joint injection relieved their symptoms, including groin tenderness. In our experience, groin tenderness is highly specific for sacroiliac joint dysfunction. We speculate that spasm of the iliac muscle can cause groin pain and tenderness. Groin pain and a history of unexplained abdominal pain, with lower back pain, are symptoms that suggest sacroiliac joint dysfunction. Additionally, compression of the iliac muscle is a simple and useful maneuver; therefore, it can be used as a screening test for sacroiliac joint dysfunction, alongside other provocation tests.

Abstract
Detailed changes involved in the worsening of the fused segment angle were assessed after application of the Williams-Isu method using autologous bone grafts from cervical vertebral bodies in 30 patients with cervical disease treated by single-level anterior fusion. The mean follow-up duration was 25.4 months. The fused segment angle was measured on serial radiographs. Whole cervical spine alignment changed from 12.8° to 9.9°. The alignment of the fused segment worsened by mean 3.3°. To elucidate the characteristics of worsening of the fused segment, the 30 patients were divided into 2 groups: Group I (n = 20) without and Group II (n = 10) with postoperative worsening of the fused segment. The loss in the fused segment angle was significantly greater in Group II (8.0°) than Group I (0.9°). Preoperative range of motion and disc height were significantly greater in Group II than Group I. Worsening of the fused segment angle occurred within 1 month in Group I, whereas stabilization was observed after 3 months in Group II. Graft subsidence was primarily posterior and inferior. Our results indicate that the preoperative range of motion and disc height of the fused segment must be considered to prevent worsening in that segment after anterior fusion. Such detailed information is useful for the selection and postoperative monitoring of patients eligible for treatment by the Williams-Isu method.

Abstract
This 60-year-old man with cervical spondylosis experienced bilateral arm pain and weakness. After anterior cervical fusion and posterior decompression at a local hospital his symptoms worsened and he was admitted to our hospital. On admission he manifested bilateral motor weakness, neuropathic pain, and numbness below the C5 level. Radiological findings showed spinal cord compression at the C4 to C7 level. He again underwent posterior decompression and anterior fusion. Although his paresis was improved, his severe neuropathic pain and numbness persisted. Because treatment with NSAIDs, clonazepam, and gabapentin failed to control his symptoms we administered ketamine (NMDA receptor antagonist) because his symptoms were alleviated upon ketamine test challenge. His severe symptoms improved and there were no complications. However, upon cessation of ketamine treatment they reappeared. Therefore, we continued daily ketamine treatment for 6 months, after which we changed to codeine phosphate. His symptoms were controlled without any complications. Ketamine is useful for the control of severe neuropathic pain, however, as long-term ketamine administration is inadvisable, we suggest that treatment be tailored to each patient's particular clinical status.

Abstract
A 31-year-old woman presented with worsening numbness and pain in the arms and chest. Neurological findings at admission were decreased pain sensation and temperature sensation in the arms and chest. Magnetic resonance demonstrated a large cervical syrinx from the level of C4 to Th4 associated with Chiari I malformation. Occipital craniectomy and C1 laminectomy were performed for foramen magnum decompression. Intraoperative ultrasonography, performed after removal of the outer membrane of the dura mater at the level of the foramen magnum, revealed insufficient decompression. Therefore, the dura mater was completely opened and duraplasty was performed with a polyglycolic acid patch and fibrin glue. Sufficient decompression was thus achieved. The neurological symptoms and signs improved within the first postoperative month, and magnetic resonance showed a decrease in the size of the syrinx and no cerebrospinal fluid leakage. In patients undergoing foramen magnum decompression with duraplasty, the use of a polyglycolic acid patch and fibrin glue renders suturing unnecessary and avoids the common complications associated with suture duraplasty.

Abstract
Sacroiliac joint (SIJ) can cause low back pain when its joint capsule and ligamentous tissue are damaged. We report our experience in treating three SIJ dysfunction patients presenting with acute low back pain (a 38 year-old male, a 24 year-old male, and a 32 year-old female). SIJ dysfunction was diagnosed using the one-finger test, the modified Newton test, and SIJ injection. In all three patients, lumbar MRI demonstrated slightly degenerated lumbar lesions (lumbar canal stenosis, lumbar disc hernia). Two patients had paresthesia or pain in the leg and all three patients showed iliac muscle tenderness in the groin, which was thought to be a referred symptom because of improvement after SIJ injection. The two male patients returned to work and the problems have not recurred. Although our female patient resumed daily life as a housewife, her condition recurred at intervals of 2-3 months and she required regular SIJ injections. The prevalence of SIJ dysfunction of low back pain is about 10%, so it should be considered as a differential diagnosis when treating low back pain and designing treatment for lumbar spinal disorders.
