To investigate the sonographic features of plantar fasciitis (PF).
High-resolution ultrasound was used to measure the thickness and echogenicity of the proximal plantar fascia and associated heel pad thickness for 102 consecutive patients with PF (unilateral: 81, bilateral: 21) and 33 control subjects.
The mean thickness of the plantar fascia was greater on the symptomatic side for patients with bilateral and unilateral PF than on the asymptomatic side for patients with unilateral PF, and also control subjects (5.47+/-1.09, 5.61+/-1.19, 3.83+/-0.72, 3.19+/-0.43 mm, respectively, p<0.001). A substantial difference in thickness between the asymptomatic side of patients with unilateral PF and control subjects was also noted (p=0.001). The heel pad thickness was not show different between control subjects and patients with PF. The incidence of hypoechoic fascia was 68.3% (84/123). Other findings among the patients from our test group included intratendinous calcification (two cases), the presence of perifascial fluid (one case), atrophic heel pads (one case), and the partial rupture of plantar fascia (one case).
Increased thickness and hypoechoic plantar fascia are consistent sonographic findings in patients exhibiting PF. These objective measurements can provide sufficient information for the physician to confirm an initial diagnosis of PF and assess individual treatment regimens.
探讨足底筋膜炎（PF）的超声特征。
采用高分辨率超声对102例连续的PF患者（单侧：81例，双侧：21例）及33例对照者测量足底筋膜近端厚度、回声及相关足跟垫厚度。
双侧和单侧PF患者患侧足底筋膜平均厚度均大于单侧PF患者无症状侧及对照者（分别为5.47±1.09、5.61±1.19、3.83±0.72、3.19±0.43mm，p<0.001）。单侧PF患者无症状侧与对照者之间厚度也存在显著差异（p=0.001）。对照者与PF患者足跟垫厚度无差异。低回声筋膜发生率为68.3%（84/123）。试验组患者的其他表现包括肌腱内钙化（2例）、筋膜周围积液（1例）、足跟垫萎缩（1例）及足底筋膜部分撕裂（1例）。
足底筋膜厚度增加及低回声是PF患者一致的超声表现。这些客观测量可为医生确诊PF初始诊断及评估个体化治疗方案提供充分信息。
