UNASSIGNED: A retrospective review of 38 patients who underwent fluoroscopy guided SIJ injection was conducted, for which IRB approval was granted by the MetroWest Medical Center Institutional Review Board. Patient demographics (age, sex, BMI) and pre- and post-operative numerical rating scale (NRS) scores were collected, and initial needle location was reviewed. Patients were placed into groups according to initial needle location. Statistical analysis was conducted using a Mann-Whitney U-test with significance defined as p < 0.05.
UNASSIGNED: The 21 females and 17 males had a mean age and BMI of 70.5 years and 27.8 kg/m2, respectively. Thirty-one patients had initial intraarticular needle placement confirmed with lateral arthrogram, and 7 patients had initial periarticular needle placement, requiring needle readjustment in lateral confirmatory view. Both groups had similar demographic characteristics. No statistically significant differences were found between the two groups\' mean NRS score improvement (p=0.108).
UNASSIGNED: Using only the AP or oblique view during needle placement results in miss rates of nearly 20% while adding a lateral view can lower miss rates to near 0%. While pain relief may be adequate in either case, proper diagnosis and future management relies upon accurate needle placement.
■对38例透视引导下注射SIJ的患者进行回顾性分析,IRB批准由MetroWest医疗中心机构审查委员会批准。患者人口统计学(年龄,性别,收集BMI)和手术前后数字评定量表(NRS)评分,并回顾了最初的针头位置。根据初始针头位置将患者分组。使用Mann-WhitneyU检验进行统计学分析,显著性定义为p<0.05。
■21名女性和17名男性的平均年龄和BMI分别为70.5岁和27.8kg/m2。31例患者经外侧关节造影证实有初始关节内针放置,7例患者最初放置关节周围针,需要在横向确认视图中重新调整针。两组人口统计学特征相似。两组平均NRS评分改善无统计学差异(p=0.108)。
■在针头放置期间仅使用AP或斜视图导致近20%的错失率,而添加横向视图可以将错失率降低到接近0%。虽然疼痛缓解可能是足够的,在这两种情况下,正确的诊断和未来的管理依赖于准确的针头放置。
