A prospective study of pes planus by using calcaneal pitch and calcaneal spur was carried out in 82 patients with plantar heel pain and in 400 normal subjects. The mean normal calcaneal pitch was 20.54 degrees. The mean calcaneal pitch in patients with plantar heel pain was 15.99 degrees, which was significantly lower than in normal subjects. The incidence of calcaneal spur in normal subjects and in patients with plantar heel pain was 15.5% percent (62 of 400) and 65.9% (54 of 82), respectively. Again, this was a highly significant difference. Excessive weight gain, aging, and gender may be important factors effecting the lowering of the pitch and the increasing of spur formation. These factors could lead to the development of plantar heel pain.
一项利用跟骨倾斜度和跟骨骨刺对扁平足进行的前瞻性研究，纳入了82例足底足跟痛患者和400名正常受试者。正常跟骨倾斜度的平均值为20.54度。足底足跟痛患者的跟骨倾斜度平均值为15.99度，显著低于正常受试者。正常受试者和足底足跟痛患者的跟骨骨刺发生率分别为15.5%（400例中的62例）和65.9%（82例中的54例）。同样，这是一个非常显著的差异。体重过度增加、衰老和性别可能是影响倾斜度降低和骨刺形成增加的重要因素。这些因素可能导致足底足跟痛的发生。
