A paired case cohort study was performed using retrospective review of operative times for defined hand surgical procedures in an attempt to quantify efficiency with and without the use of portable fluoroscopy. Patients included in the study underwent 1 of 4 defined surgical procedures controlled to ensure similar operative technique (total wrist fusion, in situ 4-corner fusion, closed reduction/internal fixation using K-wires of phalangeal shaft fractures, and metacarpophalangeal or interphalangeal joint fusions using K-wires). One group used intraoperative standard film radiographs and the other used portable mini-fluoroscopy to examine hardware placement. Both groups were paired by operative procedure to eliminate procedure bias on overall operating time. Analysis demonstrated a 38% reduction in total operative time in the group using portable mini-fluoroscopy compared with standard intraoperative radiographs.
开展了一项配对病例队列研究，通过回顾特定手部外科手术的手术时间，试图量化使用和不使用便携式荧光透视时的效率。纳入该研究的患者接受了4种特定外科手术中的1种，并对手术技术进行控制以确保相似（全腕融合术、原位四角融合术、使用克氏针对指骨干骨折进行闭合复位/内固定，以及使用克氏针对掌指关节或指间关节进行融合）。一组使用术中标准胶片X线片，另一组使用便携式微型荧光透视检查硬件放置情况。两组按手术程序配对，以消除手术程序对总体手术时间的偏倚。分析表明，与标准术中X线片相比，使用便携式微型荧光透视的组总手术时间减少了38%。
