Abstract

Purpose: To determine the added value of computed tomography (CT) to identify severe hip osteoarthritis (OA).

Materials and methods: A retrospective query of all cases of hip or knee arthroplasty planning CTs between January 2018 and March 2022 was performed. Age, sex, and symptoms were collected from the medical record. CTs were evaluated for the degree of osteoarthritis and classified using an adapted Kellgren-Lawrence (KL) grading system in the anterior, posterior, superior, and superomedial hip. Frontal hip or pelvis radiographs within 1 year of the CT were also graded.

Results: There were 265 eligible hips in 178 subjects, age 66 ± 11 (range 31-93) years, with 85/178 (48%) males and 93/178 (52%) females, and 127/265 (48%) right and 138/265 (52%) left hips. The posterior hip joint was the most common location for grade 2/3 OA (20%), followed by superior hip joint (14%). Anterior or posterior grade 2/3 OA occurred concurrently with superior or superomedial grade 2/3 OA in 32/68 (47%) of hips. Grade 2/3 OA was detected on CT more commonly than on XR both in the superior (14 vs 8.6%, P = 0.0016) and superomedial (8.7 vs 4.8%, P = 0.016) hip joint. Of the 71 symptomatic hips, 22 (31%) hips demonstrated either anterior and/or posterior grade 2/3 OA on CT, and 9 (9/22, 41%) of these hips had superior or superomedial grade 0/1 OA.

Conclusion: CT may be warranted when the patient has pain suggestive of osteoarthritis not detected on radiographs.

髋关节前后骨关节炎：CT 与射线照片的流行程度和潜在价值比较。

目的：确定计算机断层扫描（CT）在识别严重髋关节骨关节炎（OA）方面的附加值：对2018年1月至2022年3月期间所有计划进行CT的髋关节或膝关节置换术病例进行回顾性查询。从病历中收集了年龄、性别和症状。对 CT 进行骨关节炎程度评估，并使用改编的 Kellgren-Lawrence （KL）分级系统对髋关节前部、后部、上部和上内侧进行分类。CT检查后一年内的髋关节或骨盆正面X光片也进行了分级：178名受试者中有265个符合条件的髋关节，年龄为66 ± 11（31-93岁），其中男性85/178（48%），女性93/178（52%）；右髋127/265（48%），左髋138/265（52%）。髋关节后方是最常见的2/3级OA部位（20%），其次是髋关节上方（14%）。在32/68（47%）的髋关节中，前方或后方2/3级OA与上方或超内侧2/3级OA同时发生。在髋关节上侧（14% 对 8.6%，P = 0.0016）和髋关节内侧上侧（8.7% 对 4.8%，P = 0.016），CT 比 XR 更常发现 2/3 级 OA。在71个有症状的髋关节中，22个（31%）髋关节在CT上显示为前部和/或后部2/3级OA，其中9个（9/22，41%）髋关节的上部或上内侧为0/1级OA：结论：当患者的疼痛提示骨关节炎而X光片却未发现时，可能需要进行CT检查。

期刊介绍： Skeletal Radiology provides a forum for the dissemination of current knowledge and information dealing with disorders of the musculoskeletal system including the spine. While emphasizing the radiological aspects of the many varied skeletal abnormalities, the journal also adopts an interdisciplinary approach, reflecting the membership of the International Skeletal Society. Thus, the anatomical, pathological, physiological, clinical, metabolic and epidemiological aspects of the many entities affecting the skeleton receive appropriate consideration. This is the Journal of the International Skeletal Society and the Official Journal of the Society of Skeletal Radiology and the Australasian Musculoskelelal Imaging Group.
