UNASSIGNED: A retrospective analysis was conducted on a series of consecutive patients who underwent P-US guided intra-articular injections following a chief complaint of forefoot or midfoot joint pain. Patients reported their pain levels using the Visual Analog Scale (VAS) pre-injection and at 3 months follow-up. The procedure was performed by an experienced foot and ankle surgeon using a linear array transducer for guidance, and a 25-gauge needle was used to inject a combination of 2 cc 1% lidocaine and 12 cc of Kenalog (40 mg/ml). Complications and pain scores were analyzed using a paired t-test and p < 0.05 was considered significant.
UNASSIGNED: We included 16 patients, 31% male and 69% female with a mean age (±SD) of 61.31 (±12.04) years. None of the patients experienced immediate complications following the intervention. The mean pre-injection VAS score was significantly reduced from 5.21 (±2.04) to a mean of 0.50 (±1.32) at 3 months follow-up (P < 0.001). Thirteen patients reported complete resolution of pain at the 3-month follow-up. No adverse events were reported throughout the duration of the study.
UNASSIGNED: This pilot study suggests P-US-guided intra-articular injections offer a safe and effective method for managing forefoot and midfoot joint pain caused by various arthritic pathologies. Further research is warranted to establish the long-term efficacy and comparative effectiveness of P-US-guided injections in larger patient cohorts as compared to non-image guided injections.
■对一系列连续患者进行回顾性分析,这些患者在主诉前足或中足关节疼痛后接受了P-US指导的关节内注射。患者在注射前和3个月随访时使用视觉模拟量表(VAS)报告其疼痛水平。手术由经验丰富的足踝外科医生使用线性阵列传感器进行指导,使用25号针头注射2cc1%利多卡因和12ccKenalog(40mg/ml)的组合。使用配对t检验分析并发症和疼痛评分,并且p<0.05被认为是显著的。
■我们纳入了16名患者,31%的男性和69%的女性,平均年龄(±SD)为61.31(±12.04)岁。干预后,没有患者立即出现并发症。在3个月随访时,平均注射前VAS评分从5.21(±2.04)显著降低至平均0.50(±1.32)(P<0.001)。13例患者在3个月的随访中报告疼痛完全缓解。在整个研究期间没有报告不良事件。
■这项初步研究表明,P-US指导的关节内注射为治疗各种关节炎病变引起的前足和中足关节疼痛提供了一种安全有效的方法。与非图像引导注射相比,需要进一步研究以确定P-US引导注射在较大患者队列中的长期疗效和比较有效性。
