Abstract

Background: To evaluate the relationship between the pattern and severity of metatarsophalangeal (MTP) joint dislocation in the lesser toes and severity of joint destruction in rheumatoid forefoot deformities.

Methods: Participants comprised of 13 patients (16 feet) who underwent resection arthroplasty of the metatarsal head of the lesser toes for rheumatoid arthritis of the MTP joints. Correlations between preoperative radiographic findings and histological grades second to fifth metatarsal heads taken intraoperatively were analyzed.

Results: In 62 metatarsal heads, complete dislocation of the MTP joint in the lesser toes significantly resulted in severe joint destruction compared to mild or moderate dislocation (P < 0.05). The proportion of severe cartilage damage in MTP joints with complete dislocation was 100 % in the 5th MTP joint, 83.3 % in the 4th MTP joint, and 58.3 % in the 2nd and 3rd MTP joints. Moreover, complete dislocation of the MTP joints in the lateral column showed the most severe joint destruction compared to that in the medial column (P = 0.03).

Conclusion: Complete dislocation of the MTP joint in the lateral column is related to joint destruction in rheumatoid forefoot deformities.

关节面破坏与跖趾关节脱位引起的类风湿前足畸形有较高的关联性。
背景:目的:评估类风湿性前足畸形患者小趾跖趾关节(MTP)脱位的模式和严重程度与关节破坏严重程度之间的关系:参与者包括13名因MTP关节类风湿性关节炎而接受小趾跖骨头切除关节成形术的患者(16只脚)。分析了术前X光检查结果与术中第二至第五跖骨头组织学分级之间的相关性:在 62 个跖骨头中,与轻度或中度脱位相比,小趾的 MTP 关节完全脱位明显导致严重的关节破坏(P 结论:小趾的 MTP 关节完全脱位会导致严重的关节破坏:在类风湿性前足畸形中,外侧柱的MTP关节完全脱位与关节破坏有关。
