【摘要】：目的:設(shè)計(jì)一套髕骨軸位X線檢查輔助裝置,以滿(mǎn)足膝關(guān)節(jié)不同程度屈曲受限患者髕骨軸位X線攝影及其臨床應(yīng)用價(jià)值。方法:髕骨軸位輔助裝置制作材料均使用不銹鋼材質(zhì),由膝部定位組件和探測(cè)器支撐組件兩部分組成。本研究納入100例膝關(guān)節(jié)髕股關(guān)節(jié)炎患者,膝關(guān)節(jié)均有不同程度屈曲受限,使用輔助裝置進(jìn)行髕骨軸位攝影,由2名擅長(zhǎng)骨關(guān)節(jié)影像診斷的高年資影像醫(yī)師觀察髕骨軸位圖像,并對(duì)其主要解剖結(jié)構(gòu)顯示能力及圖像質(zhì)量進(jìn)行評(píng)價(jià)。結(jié)果:使用髕骨軸位輔助裝置首次攝影成功率為98%,優(yōu)級(jí)片率為93%,圖像質(zhì)量符合診斷要求;能夠在膝關(guān)節(jié)屈曲不同角度(15°~90°)下拍攝髕骨軸位,并清晰顯示髕骨運(yùn)行軌跡情況以及準(zhǔn)確測(cè)量髕骨溝角、適合角等相關(guān)參數(shù)。結(jié)論:使用髕骨軸位X線檢查輔助裝置簡(jiǎn)單、易行、攝影成功率高,圖像質(zhì)量符合影像診斷學(xué)要求。對(duì)于髕股關(guān)節(jié)炎、髕骨習(xí)慣性脫位、髕骨骨折的診斷有一定的臨床價(jià)值。
[Abstract]:Objective: to design a patellar axial radiographic apparatus to meet the clinical application value of patellar axial radiography in patients with different degree of knee flexion limitation. Methods: the materials of patellar axial position auxiliary device were made of stainless steel and consisted of knee positioning assembly and detector support assembly. In this study, 100 patients with patellofemoral arthritis of the knee joint were included. The knee joint had different degree of flexion limitation. The axial patellar radiography was performed with auxiliary device. The axial patellar images were observed by 2 senior radiographers who were good at the diagnosis of osteoarthrosis. The display ability and image quality of its main anatomical structure were evaluated. Results: the success rate of patellar axial position was 98, the excellent film rate was 93, the image quality was in line with the diagnostic requirements, and the axial position of patella could be photographed at different angles of knee flexion (15 擄to 90 擄). The patellar trajectory was clearly displayed and the patellar groove angle and suitable angle were measured accurately. Conclusion: it is simple and easy to use the auxiliary device of patellar axial X-ray examination, and the success rate of photography is high. The image quality meets the requirements of imaging diagnostics. The diagnosis of patellofemoral arthritis, habitual dislocation of patella and fracture of patella has certain clinical value.
