Abstract

Background: Weightbearing computed tomography (WBCT) has been increasingly employed to evaluate and treat patients with varied pathologies such as progressive collapsing foot deformity (PCFD), posttraumatic deformity, hallux valgus, ankle arthritis, Charcot arthropathy, lisfranc, and syndesmosis injuries. However, little is known regarding its overall availability to foot and ankle providers and how it is being used in clinical practice. The goal of this study is to assess the utilization of WBCT among AOFAS members, identify the indications for use in clinical practice and potential barriers for implementation.

Methods: A survey was emailed to AOFAS members inquiring about the use WBCT in clinical practice. Practice and demographic information were also collected. A total of 220 responses were collected over a 2-month period. Respondents were queried with respect to the availability of WBCT in practice, indications for use, frequency of use, ownership of the scanner, and barriers to implementation.

Results: 58% of respondents did not have access to WBCT. Most respondents were in practice 10 years or more (69%). Single-specialty private practice was the most common practice type (39%). Of those with access to WBCT, 5 or fewer scans were ordered per week (57% of respondents). Evaluation of hindfoot/ankle deformity was the most common indication (69% of respondents) with it being used as a preoperative evaluation tool approximately 25% of the time (57% of respondents). Radiology department owned WBCT in most institutions (34%). 75% of respondents with WBCT use it postoperatively less than 25% of the time. Of those without WBCT, 94% stated they would like to have it with cost being the most significant barrier to implementation.

Conclusion: Most respondents surveyed did not have access to WBCT, with cost being the greatest barrier. However, 94% of those without it would like to have access to it. For those with access, it is used 5 or fewer times per week with evaluation of hindfoot/ankle deformity being the most common indication.

Level of evidence: Level IV (Observational Study).

关于 AOFAS 会员使用负重计算机断层扫描的调查。
背景:负重计算机断层扫描(WBCT)越来越多地被用于评估和治疗各种病症的患者,如进行性塌足畸形(PCFD)、创伤后畸形、足外翻、踝关节炎、Charcot 关节病、lisfranc 和巩膜损伤。然而,人们对其在足踝医疗机构的总体可用性以及在临床实践中的使用情况知之甚少。本研究的目的是评估 AOFAS 会员对 WBCT 的使用情况,确定其在临床实践中的使用适应症以及潜在的实施障碍:方法:通过电子邮件向 AOFAS 会员发送调查问卷,询问 WBCT 在临床实践中的使用情况。同时还收集了实践和人口统计信息。在两个月的时间里,共收集到 220 份回复。调查询问了受访者在临床实践中是否使用 WBCT、使用适应症、使用频率、扫描仪的所有权以及实施障碍:结果:58%的受访者没有使用 WBCT。大多数受访者从业时间在 10 年或以上(69%)。单一专科私人诊所是最常见的诊所类型(39%)。在可以使用 WBCT 的受访者中,每周订购的扫描次数为 5 次或更少(57% 的受访者)。评估后足/踝关节畸形是最常见的适应症(69% 的受访者),约有 25% 的时间将其用作术前评估工具(57% 的受访者)。大多数机构的放射科都拥有 WBCT(34%)。在拥有 WBCT 的受访者中,75% 的受访者在术后使用 WBCT 的比例低于 25%。在没有 WBCT 的受访者中,94% 的人表示他们希望拥有 WBCT,而成本是实施 WBCT 的最大障碍:结论:大多数受访者无法使用 WBCT,费用是最大的障碍。然而,94% 的受访者表示希望能够使用。对于那些有条件的受访者来说,每周使用 5 次或更少,评估后足/踝关节畸形是最常见的适应症:证据级别:IV 级(观察性研究)。
