摘　　要：[目的]通过对小趾囊炎足与正常足X线的测量及对比分析研究,明确小趾囊炎足X线诊断标准。[方法]对131例正常足与117例小趾囊炎足的第4～5跖骨间角(IM4～5),改良4～5跖骨间角(MIM4～5),小趾内翻角(MPA),第5跖骨外翻角(LDA),第5跖骨头宽度(WMH)及突出距离(DPMH)进行X线测量,结合临床对测量结果进行对比分析研究。[结果]小趾囊炎足与正常足平均测量结果分别为:第4～5跖骨间角13.57°±2.99°和8.88°±1.88°,改良4～5跖骨间角12.80°±2.86°和9.28°±2.13°,小趾内翻角18.47°±6.22°和9.96°±5.39°,第5跖骨外翻角6.55°±4.06°和3.36°±2.10°,第5跖骨头宽度13.27mm±1.59mm和12.00mm±1.25mm,第5跖骨头突出距离3.91mm±1.08mm和3.12mm±0.74mm。正常足的范围:第4～5跖骨间角5.19°～12.58°,改良4～5跖骨间角5.09°～13.47°,小趾内翻角1.38°～19.04°,第5跖骨外翻角1.21°～7.59°,第5跖骨头宽度9.55mm～14.45mm,第5跖骨突出距离1.65mm～4.59mm。小趾囊炎足与正常足X线各测量值的差异均有统计学意义(P<0.01)。小趾囊炎足中第4～5跖骨间角与小趾内翻角之间存在正相关,相关系数r为0.36(P<0.05)。[结论]X线测量是诊断小趾囊炎的重要临床指标。第4～5跖骨间角>9°、小趾内翻角>10°、第5跖骨外翻角>3°并伴有临床症状的患者可诊断为小趾囊炎。[ Objective] To identify the standard of radiographic diagnosis and analyse the measurement between tailor＇s bunion and normal feet. [ Methods] The fourth - fifth intermetatarsal angle （ IM4 - 5 ） , modified fourth - fifth intermetatarsal angle （ MIM4 - 5 ） , metatarsophalangeal - fifth angle （ MPA）, lateral deviation of the fifth metatarsal angle （ LDA）, width of fifth metatarsal head （WMH） , distance of prominence of the fifth metatarsal head （DPMH） were measured by X -ray for 131 feet of normal persons and 117 feet of tailor＇s bunion. The measured results and other clinical presentations were compared. [Results] The IM4-5 were 13.57° ± 2. 99° and 8.88° ± 1.88° on average. MIM4 - 5 were 12. 80° ± 2. 86° and 9. 28° ± 2. 13°on average. MPA were 18.47° ± 6. 22° and 9. 96° ±5.39° on average. LDA were 6. 55° ±4. 06°and 3.36° ± 2. 10° on average. WMH were 13.27 mm ± 1.59 mm and 12. 00 mm ± 1.25mm on average. DPMH were 3.91 mm ＋ 1.08 mm and 3. 12 mm ±0. 74 mm on average in patients and normal feet. In the normal persons： IM4-5 were 5. 19° to 12. 58°, MIM4 -5 were 5.09° to13.47° , MPA 1.38° to 19. 04° , LDA 1.21° to 7.59° , WMH 9. 55 mm to 14. 45 mm, and DPMH 1.65 mm to 4. 59 mm. There were statistically difference in each measured value between normal feet and tailor＇s bunion （P 〈 0.01 ） . The IM4 5 is positively correlated with the MPA in the group of tailor＇ s bunion （ r = 0. 36, P 〈 0.05 ） . [ Conclusian ] The radiographic measurement is an important clinical - index for diagnosis of tailor＇ s bunion. The diagnosis of tailor＇s bunion is based on clinical presentations and radiographic angles （IM4 -5 〉 9°, MPA 〉 10° and LDA 〉 3°） .
