The aim of this study was to investigate foot deformities in patients with rheumatoid arthritis (RA), to detect frequency of deformities and to assess the relationship between foot deformities and foot functions.
Anteroposterior and lateral radiographs of 40 patients and 40 control subjects were studied. The hallux valgus (HV) angle, intermetatarsal angle between first and second metatarsals, intermetatarsal angle between first and fifth metatarsals, and calcaneal pitch were measured on radiographs. Foot functions were measured by the Foot and Ankle Outcome Score (FAOS).
The frequency of foot deformities in RA patients was determined as 78.8%. The most frequent foot deformity in RA patients was HV (62.5%), followed by metatarsus primus varus (MPV) (41.3%). MPV and splaying of the forefoot deformities were significantly more frequent in RA patients than the control group (P < 0.05). Mild to moderate effect on FAOS subscales was observed in RA patients. There was a slight, but significant correlation between the foot deformities and the FAOS subscales except for quality of life subscale.
In this study, it has been shown that foot deformities are frequent in patients with RA and that there is slight deterioration in foot functions related to RA. Our results indicated that foot deformities have small, but clinically important changes on foot functions. There is a need for more studies, which evaluates the foot deformities, to further explore the relationship between the foot deformities and foot function in patients with RA.
本研究旨在调查类风湿关节炎（RA）患者的足部畸形，检测畸形的频率，并评估足部畸形与足部功能之间的关系。
对 40 例患者和 40 例对照者的前后位和侧位 X 线片进行了研究。在 X 线片上测量了踇外翻（HV）角、第一和第二跖骨之间的跖间角、第一和第五跖骨之间的跖间角以及跟骨倾斜角。足部功能通过足踝结局评分（FAOS）进行测量。
RA 患者的足部畸形发生率为 78.8%。RA 患者最常见的足部畸形是 HV（62.5%），其次是第一跖骨内翻（MPV）（41.3%）。RA 患者的 MPV 和前足外展畸形明显比对照组更常见（P < 0.05）。RA 患者的 FAOS 亚量表存在轻度至中度影响。除生活质量亚量表外，足部畸形与 FAOS 亚量表之间存在轻微但显著的相关性。
本研究表明，RA 患者的足部畸形很常见，与 RA 相关的足部功能有轻微恶化。我们的结果表明，足部畸形对足部功能有小但具有临床意义的改变。需要更多的研究来评估足部畸形，以进一步探讨 RA 患者足部畸形与足部功能之间的关系。
