Study Design: Retrospective case-control study. Purpose: To determine whether kissing spine is a risk factor for recurrence of sciatica after lumbar posterior decompression using a spinous process floating approach. Overview of Literature: Kissing spine is defined by apposition and sclerotic change of the facing spinous processes as shown in X-ray images, and is often accompanied by marked disc degeneration and decrement of disc height. If kissing spine significantly contributes to weight bearing and the stability of the lumbar spine, trauma to the spinous process might induce a breakdown of lumbar spine stability after posterior decompression surgery in cases of kissing spine. Methods: The present study included 161 patients who had undergone posterior decompression surgery for lumbar canal stenosis using a spinous process floating approaches. We defined recurrence of sciatica as that resolved after initial surgery and then recurred. Kissing spine was defined as sclerotic change and the apposition of the spinous process in a plain radiogram. Preoperative foraminal stenosis was determined by the decrease of perineural fat intensity detected by parasagittal T1-weighted magnetic resonance imaging. Preoperative percentage slip, segmental range of motion, and segmental scoliosis were analyzed in preoperative radiographs. Univariate analysis followed by stepwise logistic regression analysis determined factors independently associated with recurrence of sciatica. Results: Stepwise logistic regression revealed kissing spine (p =0.024; odds ratio, 3.80) and foraminal stenosis (p <0.01; odds ratio, 17.89) as independent risk factors for the recurrence of sciatica after posterior lumbar spinal decompression with spinous process floating procedures for lumbar spinal canal stenosis. Conclusions: When a patient shows kissing spine and concomitant subclinical foraminal stenosis at the affected level, we should sufficiently discuss the selection of an appropriate surgical procedure.

Objective: Since there have been few large series studies to date, we investigated the relationship between Trousseau's syndrome associated with cerebral infarction and its clinical associations with ovarian cancer. Methods: In this study, we investigated the association between cerebral infarction onset and ovarian cancer. Eight-hundred twenty-seven consecutive ovarian cancer patients from 4 affiliated academic institutions were included in the study over a 12 years period. All patients were histopathologically diagnosed as epithelial ovarian cancer and were analyzed retrospectively. Results: The 27 patients (3.2%) presented with cerebral infarction during the study period, 14 patients onset prior to treatment (1.7%), and 13 patients onset after start of initial treatment (1.5%). Univariate analysis and multivariate analysis was performed for onset of Trousseau's syndrome and various clinical and pathological parameters. There was no statistical significance between the occurrence of Trousseau's syndrome with age or International Federation of Gynecology and Obstetrics (FIGO) stage; however, univariate analysis and multivariate analysis demonstrated a statistically significant association between clear cell carcinoma (CCC) and non-CCC histology. Conclusion: Thus, our results demonstrate that Trousseau's syndrome with cerebral infarction occurred with greater incidence among CCC cases compared to non-CCC cases.
