Background: Several classification systems exist for sacral fractures; however, these systems are primarily descriptive, are not uniformly used, have not been validated, and have not been associated with a treatment algorithm or prognosis. The goal of the present study was to demonstrate the reliability of the AOSpine Sacral Classification System among a group of international spine and trauma surgeons. Methods: A total of 38 sacral fractures were reviewed independently by 18 surgeons selected from an expert panel of AOSpine and AOTrauma members. Each case was graded by each surgeon on 2 separate occasions, 4 weeks apart. Intrarater reproducibility and interrater agreement were analyzed with use of the kappa statistic (κ) for fracture severity (i.e., A, B, and C) and fracture subtype (e.g., A1, A2, and A3). Results: Seventeen reviewers were included in the final analysis, and a total of 1,292 assessments were performed (646 assessments performed twice). Overall intrarater reproducibility was excellent (κ = 0.83) for fracture severity and substantial (κ = 0.71) for all fracture subtypes. When comparing fracture severity, overall interrater agreement was substantial (κ = 0.75), with the highest agreement for type-A fractures (κ = 0.95) and the lowest for type-C fractures (κ = 0.70). Overall interrater agreement was moderate (κ = 0.58) when comparing fracture subtype, with the highest agreement seen for A2 subtypes (κ = 0.81) and the lowest for A1 subtypes (κ = 0.20). Conclusions: To our knowledge, the present study is the first to describe the reliability of the AOSpine Sacral Classification System among a worldwide group of expert spine and trauma surgeons, with substantial to excellent intrarater reproducibility and moderate to substantial interrater agreement for the majority of fracture subtypes. These results suggest that this classification system can be reliably applied to sacral injuries, providing an important step toward standardization of treatment.

Study Design: Epidemiological retrospective study. Objective: To describe the demographics, timing to surgery, delay, short-term neurological recovery, and complications in surgically treated subaxial cervical trauma in a resource-constrained country. Methods: Thirty consecutive subaxial cervical trauma patients presenting to a trauma hospital in Nepal between December 2015 and August 2017 were analyzed as a retrospective cohort. Patients were segregated into 4 groups based on the timing to surgery: within 2 days, 3 to 7 days, 8 to 30 days, and >31 days. Results: There were 27 male and 3 female patients with mean age 40 years. Twenty-four sustained fall injury, and 27 patients were from outside Kathmandu. No patients were treated within the first 48 hours; only 9 were treated between 3 and 7 days, 16 between 8 and 30 days, and 5 a month later. Major delay was finance and operating room availability. Thirteen patients had a C6C7 involvement followed by C5C6 in 6 patients. Seven patients had complete neurological deficit while 18 patients had incomplete deficit. A total of 46.7% improved their neurology in 6 months. No neurological recovery was observed in complete deficit patients. Conclusion: Seventy percent of our patients were treated longer than 1 week after injury, which would likely be considered unacceptable in most first world countries. As expected, the outcomes for many of these patients were far worse than reported in North American centers with early access to medical care and insurance. Despite this, nearly half of our patients improved neurologically following treatment; hence, surgery holds hope of some restoration of neurologic deficits.

Background: Selective Nerve Root Block using steroid is a proven technique for management of lumbar radiculopathy. The aim of the study was to determine the effectiveness of selective nerve root block in lumbar radiculopathy.Methods: A prospective observational study was conducted for duration of one year in patients diagnosed with lumbar radiculopathy. Patients with leg pain, positive straight leg raising test and single level disc prolapse were included in the study. The procedure was performed under fluoroscopic guidance and Visual Analogue Pain rating scale and Oswestry Disability Index score was used for assessment pre-injection, 1 week, 1 month, 6 months and 1-year post injection.Results: Total 35 patient with mean age of 37.7± 9.31 years were included in the study. The pre-injection Visual Analogue Pain Score(Mean ± S.D:7.8±0.7) was significantly reduced at one week (4.2±1.47, p <0.00001), one month (2.74±1.06, p <0.00001), six months (2.31±0.75, p <0.00001) and one year (2.62±0.84, p <0.00001). Similarly, pre-injection Oswestry Disability Index score (Mean ± S.D: 32.09±5.95) was significantly reduced at one week (19.51±7.26, p <0.00001), one month (12.71±4.56, p <0.00001), six months (9.8±2.87, p <0.00001) and one year (10.09±2.97, p <0.00001) but not significantly improved when compared at 6 months and 1 year (p < 0.44).Conclusions: Selective Nerve Root Block in lumbar radiculopathy significantly reduces Visual Analogue Pain Score up to a year, however, the reduction in pain plateaus around six months.Disability index score only reduces for first 6 months but doesn’t significantly reduce from six months to one year.Keywords: Lumbar; radiculopathy; selective nerve root block; steroid.

To analyze the differences between standing and supine plain film lateral radiographs of the lumbosacral region in low grade (grade I/II) spondylolisthesis using the Picture Archiving and Communication System (PACS) software. Demonstrable difference might be a parameter of instability which might be useful in planning surgical treatment when it is too painful for patients to undergo flexion/extension Xrays.Radiographs of 23 patients with low grade spondylolisthesis were analyzed for percentage slip, lumbar lordosis, disc height, sacral inclination and slip angle. These standing and supine lateral radiographs were taken at the same distance with the same magnification. Measurements obtained were statistically analyzed with the SPSS software using the student t test for statistical significance (p<0.05).A significant difference (p < 0.05) was found between the standing percentage slip (mean 36.85% +/-12.78%) and supine percentage slip (mean 27.39% +/-11.14%) (p = 0.01). Similarly, standing lumbar lordosis (mean 37.74% +/-10.96%) and supine lumbar lordosis (mean 30.96% +/-12.76%) revealed a marginally higher p value (p =0.06). However, differences in the disc space height (p=0.09), sacral inclination (p=1) and slip angle (p=0.55) did not show any statistical significance.The standing radiographs effectively demonstrate the increase in slip percentage. This can have a significant impact on the grading of slip which can influence the treatment strategy. Also the increase of slip values on standing Xrays adds a parameter of instability which might be considered in the management strategy.
