The Relationship between Calcaneal Spur Type and Plantar Fasciitis in Chinese Population.

Plantar heel pain is a common disease with a high incidence in different races. It significantly reduced the quality of life of patients. However, the cause of PHP is still controversial and there were varieties of physiological factors associated with PHP. The most common pathological factor in the population was plantar fasciitis. Some existing research studies had found a correlation between calcaneal spurs and plantar fasciitis, and this study had found the correlation in Chinese population. It is invaluable not only to understand the relationship between different types of plantar calcaneal spurs and plantar fasciitis but also to identify the most appropriate treatment strategies. A total of 71 patients with calcaneal spurs were chosen from the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University. All 71 patients had completed X-rays and MRI scans; then, surgeons had removed their plantar calcaneal spurs. After surgery, all patients were followed up for 12 months; their prognosis was tested by the VAS and AOFAS scores. Type II (29, 40.8%) had the highest incidence in Chinese population, followed with type I (24, 33.8%) and type III (18, 25.4%). Preoperative VAS scores showed that type II (7.72 ± 1.10) was significantly higher than the other two types ( < 0.001). Postoperative VAS scores of type II were higher than those of type I and type III ( < 0.001). Postoperative AOFAS scores of type II were the lowest ( < 0.001). Researchers had proved that type II was more likely to cause PF.
