The Application Value of Infrared Thermal Imaging Technology in Pain Localization for Patients with External Humeral Epicondylitis

目的探讨红外热成像在肱骨外上髁炎患者疼痛定位中的应用价值。方法将2016年10月至2018年12月郑州市第九人民医院骨科收治的78例肱骨外上髁炎患者设为观察组,同期接受健康体检的30名健康人设为对照组,采用红外热成像仪对受试者肱骨外上髁后外侧、桡骨颈外缘、肱桡关节间隙与肱骨小头等测温点进行温度测定,并与传统触诊疼痛定位法进行对比结果触诊疼痛定位检查结果显示:观察组78例患者中肱骨外上髁后外侧疼痛者64例(82.05%)、桡骨颈外缘疼痛者59例(75.64%)、肱桡关节间隙疼痛者43例(55.13%)、肱骨小头疼痛者47例(60.26%),除1例患者触诊疼痛定位检查结果显示存在桡骨颈外缘及肱桡关节间隙两处痛点,而红外热成像检测结果显示仅桡骨颈外缘温度降低外,其余患者红外热成像检测结果均与触诊疼痛定位检查结果一致,考虑为该患者疼痛描述不准所致观察组患者患侧肱骨外上髁后外侧、桡骨颈外缘、肱桡关节间隙与肱骨小头测温点温度均明显低于健侧及对照组,P均<0.05,差异具有统计学意义。结论红外热成像在肱骨外上髁炎的疼痛定位中具有一定应用价值,可为临床后续治疗提供参考。

Objective To explore the value of infrared thermal imaging technology in pain localization for patients with external humeral epicondylitis.Methods Seventy-eight patients with external humeral epicondylitis,admitted to Ninth People’s Hospital of Zhengzhou from October 2016 to December 2018,were set as observation group and 30 healthy people who underwent physical examination during the same period were set as control group.The infrared thermal imager was used to measure their temperature in the posterior and lateral sides of external epicondyle of humerus,the outer edge of the radial neck,the humeroradial joint space and capitulum of humerus.Such technology was compared with traditional method of pain localization through palpation.Results The results of pain localization through palpation showed that among 78 patients in the observation group,64(82.05%)had pain in the posterior-lateral side of external epicondyle of humerus,59(75.64%)in the outer edge of the radial neck,and 43(55.13%)in the humeroradial joint space,47(60.26%)in capitulum of humerus.The result of pain localization through palpation in one patient showed two pain points in the outer edge of the radial neck and the humeroradial joint space,and the result of infrared thermal imaging technology showed that only temperature at the outer edge of the radial neck decreased.The results of infrared thermal imaging of the remaining patients were consistent with that of pain localization through palpation.Where the results of the two methods were inconsistent was presumably because the patient’s description was inaccurate.In the observation group,the temperature in the posterior and lateral sides of the lateral epicondyle of humerus,the outer edge of the radial neck,the humeroradial joint space,and capitulum of humerus at the affected sides were significantly lower than those at the uninjured sides and lower than those in the control group(all P<0.05)and the comparison showed statistically significant difference.Conclusion Infrared thermal imaging technology has certain application value in localizing pain of external humeral epicondylitis and can provide reference for subsequent clinical treatment.
