The aim of this study was to compare radiation exposure of the patient during the closed reduction and proximal femoral nailing (PFN) of the trochanteric region fractures of the proximal femur using a traction table (TT) or a radiolucent table (RT) in the supine position.
Between June 2019 and December 2020, the study included 42 patients (19 males, 23 females; mean age: 81.2±9.5 years; range, 60 to 97 years) with trochanteric region fractures applied with closed reduction and PFN with the same implant type, 21 who underwent surgery on a TT (TT group), and 21 on a RT (RT group). The cumulative radiation dose was the primary outcome and was measured as the dose area product (DAP) in Gray cm (Gycm ). Intraoperative fluoroscopy times and amount of radiation exposure were compared between the two groups.
There was no significant difference between the two groups in terms of sex, age, body mass index, fracture side, and the AO Foundation/Orthopaedic Trauma Association (AO/OTA) fracture classification (p>0.05). No statistically significant difference was found between the TT and RT groups in terms of the mean intraoperative fluoroscopy time (48.29±22.31 and 55.95±21.54 sec, respectively; p=0.264) and amount of radiation exposure (2.26±1.86 and 2.84±1.96 Gycm , respectively; p=0.332).
Both TT and RT with the patient positioned supine provide similar results for closed reduction and PFN of trochanteric region fractures, in terms of DAP as the most reliable measurement method. The main clinical relevance of this study is that radiation exposure of the patient need not be considered while selecting the operating table.
本研究旨在比较使用牵引桌(TT)或透光桌(RT)在仰卧位行股骨近端闭合复位股骨近端髓内钉(PFN)治疗股骨转子区骨折时患者的放射暴露量。
2019 年 6 月至 2020 年 12 月,本研究纳入 42 例股骨转子区骨折患者(19 例男性,23 例女性;平均年龄:81.2±9.5 岁;年龄范围 60 岁至 97 岁),采用相同的植入物类型行闭合复位股骨近端髓内钉治疗,其中 21 例在 TT 下行手术(TT 组),21 例在 RT 下行手术(RT 组)。累积辐射剂量为主要结局指标,以格雷厘米(Gycm)表示剂量面积产物(DAP)。比较两组患者术中透视次数和辐射暴露量。
两组患者在性别、年龄、体重指数、骨折侧和美国骨科创伤协会(AO/OTA)骨折分型方面无统计学差异(p>0.05)。TT 组和 RT 组的平均术中透视时间(分别为 48.29±22.31 和 55.95±21.54 秒;p=0.264)和辐射暴露量(分别为 2.26±1.86 和 2.84±1.96 Gycm;p=0.332)差异无统计学意义。
使用 TT 或 RT 使患者仰卧位,在 DAP 方面作为最可靠的测量方法,两种方法在股骨转子区骨折闭合复位股骨近端髓内钉治疗方面结果相似。本研究的主要临床意义在于在选择手术台时无需考虑患者的辐射暴露量。
