In Africa, primary hip osteoarthritis seems to be less frequent than in Europe. Sickle cell disease is responsible for aseptic osteonecrosis of the femoral head associated with secondary hip osteoarthritis. Very little evidence is available on the influence of aetiology (primary and secondary) and radiographic status on pain and disability in a Beninese population with hip osteoarthritis.
The aim of this study was to compare the impacts of aetiology and radiographic status on pain, disability and quality of life in a Beninese population with hip osteoarthritis.
This was a descriptive cross-sectional study, including participants recruited in the Clinic of Physical Medicine and Rehabilitation at the National Teaching Hospital in Cotonou.Assessment was based on the International Classification of Functioning, Disability and Health model. The main outcomes were severity of osteoarthritis, pain, range of motion, muscle strength, gait speed and quality of life. Statistical comparisons between the aetiologies were performed using a -test or rank sum test. One-way analysis of variance was used to test the effect of radiographic status.
Forty-nine participants (26 women and 23 men; mean age [standard deviation] 40.5 [17.9] years) were recruited. According to the aetiology (59.2% and 40.8% of primary and secondary osteoarthritis, respectively), there were no significant differences for any of the outcomes. Grades I, II, III and IV osteoarthritis were observed in 22.4%, 14.3%, 26.5% and 36.7% of the participants, respectively. Participants with grade IV osteoarthritis were more affected than those with grades I, II and III based on the Kellgren and Lawrence classification.
Aetiology did not influence pain, gait speed or quality of life. Participants with grade IV osteoarthritis had more pain, were more limited in walking and had a more impaired quality of life.
在非洲，原发性髋骨关节炎的发病率似乎低于欧洲。镰状细胞病是导致与继发性髋骨关节炎相关的股骨头无菌性坏死的原因。关于病因（原发性和继发性）及影像学状态对贝宁髋骨关节炎患者疼痛和残疾的影响，现有证据极少。
本研究旨在比较病因及影像学状态对贝宁髋骨关节炎患者疼痛、残疾和生活质量的影响。
这是一项描述性横断面研究，纳入了在科托努国家教学医院物理医学与康复诊所招募的参与者。评估基于国际功能、残疾和健康分类模型。主要结局指标为骨关节炎严重程度、疼痛、关节活动范围、肌肉力量、步速和生活质量。病因之间的统计学比较采用t检验或秩和检验。单向方差分析用于检验影像学状态的影响。
共招募了49名参与者（26名女性和23名男性；平均年龄[标准差]40.5[17.9]岁）。根据病因（原发性和继发性骨关节炎分别占59.2%和40.8%），各项结局指标均无显著差异。分别有22.4%、14.3%、26.5%和36.7%的参与者观察到I级、II级、III级和IV级骨关节炎。根据凯尔格伦和劳伦斯分类法，IV级骨关节炎患者比I级、II级和III级患者受影响更大。
病因不影响疼痛、步速或生活质量。IV级骨关节炎患者疼痛更严重，行走受限更明显，生活质量受损更严重。
