Clinical features and correlation between radiographic parameters and incidence of calcaneal spur / 中华创伤骨科杂志

ABSTRACT

Objective To analyze the clinical features and the correlation between radiographic parameters and incidence of calcaneal spur in the patients from Nanfang Hospital,Southern Medical University,China.Methods Three experienced observers independently used the image acquisition and transmission system (PACS) to collect the data of lateral and axial X-ray images of calcaneus or ankle joint in neutral position from the patients with calcaneal spur and normal controls who had undergone radiological examination in Nanfang Hospital,Southern Medical University from July 2014 through December 2015.Ten radiological parameters of the foot (B(o)hler angle,Gissane angle,calcaneal inclination angle,talocalcaneal angle,talus horizontal angle,posterior facet inclination angle,calcaneal length,height of the posterior facet,absolute foot height,and calcaneal width) were measured in both the patients and normal controls.The location,morphology and length of calcaneal spurs were compared between genders,sides and age groups.Results A total of 216 parpatients were included in the study.Female patients were more than male ones,simple plantar spurs more than simple achilles tendon ones,type B spurs more than type A ones,the length of achilles tendon spurs larger than that of plantar ones,female plantar spurs more than males ones,and the length of right foot plantar spurs larger than that of left foot ones.All the differences above were statistically significant (P ＜ 0.05).There were no significant differences in the location,morphology or length of calcaneal spurs between the age group of ≤ 60 years old and the age group of ＞ 60 years old (P ＞ 0.05).The incidence of calcaneal spur were significantly correlated to Gissane angle (P =0.000,OR =0.944,95％ CI 0.917-0.973),posterior facet inclination angle (P=0.017,OR=0.957,95％ CI 0.924-0.992) and height of the posterior facet (P =0.007,OR =0.933,95％ CI O.886-0.981).Conclusions Calcaneal spur favored more females than males.Plantar spurs were more common than Achilles ones.Plantar spurs of Type B were more common than those of Type A.Achilles spurs were longer than plantar ones.More females suffered plantar spur than males.Right foot spurs were longer than left foot ones.Age had no significant influence on the spur characteristics.The incidence of spur might have been related to the Gissane angle,posterior facet inclination angle and height of the posterior facet of the foot.
