A study was undertaken to determine the frequency with which patients had pain that they attributed to their hip after total hip arthroplasty. Pain drawings were used to allow patients to localize the area of their symptoms, and the degree of pain was quantified with visual analog scales. Complete clinical and radiographic data were collected on all patients so that the occurrence of pain could be correlated with a number of parameters previously reported to affect the incidence of pain, including age, sex, activity level, length of follow-up, stem size, bone type (Dorr index), and type of stem fixation (proximally coated, fully coated, or cemented). Results indicated that type of stem fixation was the only parameter statistically correlated with a higher incidence of thigh pain. Patients with proximally coated stems were more than twice as likely to complain of pain than patients with fully coated or cemented hips (P < .01). Although the incidence of thigh pain was significantly higher with proximally coated stems, the severity was not, averaging 3.0 to 3.5 out of 10 on visual analog scale in all 3 groups. The results indicate that patients perceived pain as originating in the hip in a high percentage of cases, particularly when proximally coated stems were used.
开展了一项研究，以确定全髋关节置换术后患者将疼痛归因于髋关节的频率。使用疼痛图让患者定位其症状区域，并通过视觉模拟量表对疼痛程度进行量化。收集了所有患者完整的临床和影像学数据，以便将疼痛的发生与先前报道的一些影响疼痛发生率的参数相关联，这些参数包括年龄、性别、活动水平、随访时间、柄的尺寸、骨类型（多尔指数）以及柄的固定类型（近端涂层、全涂层或骨水泥固定）。结果表明，柄的固定类型是唯一与大腿疼痛发生率较高有统计学关联的参数。使用近端涂层柄的患者抱怨疼痛的可能性是使用全涂层或骨水泥固定髋关节患者的两倍多（P <.01）。尽管近端涂层柄的大腿疼痛发生率显著更高，但疼痛严重程度并非如此，在所有3组中，视觉模拟量表的平均得分均为3.0至3.5（满分10分）。结果表明，在高比例的病例中，患者认为疼痛源于髋关节，尤其是在使用近端涂层柄时。
