Hip dysplasia is a common source of hip pain and a known cause of early osteoarthritis of the hip.
To (1) define the population-based incidence of hip dysplasia diagnosis in young patients presenting with hip pain in a large geographically defined cohort, (2) analyze trends regarding presentation and diagnosis of hip dysplasia, and (3) report the rate and type of surgical interventions used to treat this population.
Cross-sectional study; Level of evidence, 3.
A geographic epidemiological database was queried to identify patients aged 14 to 50 years with hip pain between the years 2000 and 2016. Patient medical records were analyzed, and demographic, imaging, clinical, and treatment history were recorded. Incidence trends were examined by use of linear regression with confidence intervals for age and calendar year.
Overall, 1893 patients were included. Of these, 156 patients (196 hips) had a diagnosis of hip dysplasia. The incidence of hip dysplasia diagnosis in patients who reported hip pain was 12.7 per 100,000 person-years. Patients with dysplasia had a mean age of 26.7 ± 9.8 years, while the highest age-adjusted incidence occurred at age 14 to 18 years in both male and female patients. Female patients had double the age-adjusted incidence of male patients (cases per 100,000 person-years: 16.8 [95% CI, 13.9-19.7] vs 8.7 [95% CI, 6.6-10.8]; < .01). Of the patients who underwent magnetic resonance imaging, 77% had imaging consistent with labral pathology. Patients were treated with physical therapy (67%), intra-articular steroid injection (29%), hip arthroscopy (10%), and periacetabular osteotomy (9%). The use of hip arthroscopy significantly increased over time ( < .01), whereas the use of steroid injection and periacetabular osteotomy did not ( < .28 and < .08, respectively).
The incidence of hip dysplasia diagnosis in patients presenting with hip pain was 12.7 per 100,000 person-years. Female patients had twice the age-adjusted incidence of male patients, and the highest age-adjusted incidence occurred in the age range of 14 to 18 years in both sexes. The use of hip arthroscopy to treat patients with hip dysplasia significantly increased over time.
髋关节发育不良是髋关节疼痛的常见原因，也是已知的髋关节早期骨关节炎的病因。
（1）确定在一个地理范围明确的大型队列中，因髋关节疼痛就诊的年轻患者中基于人群的髋关节发育不良诊断发病率；（2）分析髋关节发育不良的表现和诊断趋势；（3）报告用于治疗该人群的手术干预的比率和类型。
横断面研究；证据等级，3级。
查询地理流行病学数据库，以识别2000年至2016年间年龄在14至50岁之间且有髋关节疼痛的患者。分析患者的病历，并记录人口统计学、影像学、临床和治疗史。通过使用年龄和日历年的置信区间进行线性回归来检查发病率趋势。
总体而言，共纳入1893例患者。其中，156例患者（196个髋关节）被诊断为髋关节发育不良。报告髋关节疼痛的患者中髋关节发育不良的诊断发病率为每10万人年12.7例。发育不良患者的平均年龄为26.7±9.8岁，在男性和女性患者中，年龄调整后的最高发病率均出现在14至18岁。女性患者的年龄调整发病率是男性患者的两倍（每10万人年的病例数：16.8[95%CI，13.9 - 19.7]对8.7[95%CI，6.6 - 10.8]；P <.01）。在接受磁共振成像检查的患者中，77%的成像结果与盂唇病变一致。患者接受了物理治疗（67%）、关节内类固醇注射（29%）、髋关节镜检查（10%）和髋臼周围截骨术（9%）。随着时间的推移，髋关节镜检查的使用显著增加（P <.01），而类固醇注射和髋臼周围截骨术的使用则没有（分别为P <.28和P <.08）。
因髋关节疼痛就诊的患者中髋关节发育不良的诊断发病率为每10万人年12.7例。女性患者的年龄调整发病率是男性患者的两倍，且在两性中年龄调整后的最高发病率均出现在14至18岁年龄范围内。随着时间的推移，使用髋关节镜治疗髋关节发育不良患者的情况显著增加。
