Abstract:
PURPOSE: To evaluate the sonographic findings of plantar fasciitis. MATERIALS AND METHODS: Both feet of 30patients(mean age, 44years) in whom plantar fasciitis had been clinically diagnosed, and those of healthyvolunteers(mean age, 34years) were evaluated with ultrasound(US) using a 7.0MHz linear array transducer. Heel painwas unilateral in 26 patients and bilateral in four. Sagittal sonograms were obtained in the prone position, andthe thickness of the plantar fascia was measured at its proximal end near its insertion into the calcaneus. Wealso evaluated hypoechoic fascia, perifascial fluid collection, fiber rupture, calcaneal spur and calcifications. RESULTS: Plantar fascia thickness was significantly greater in the heels of patients with plantarfasciitis(3.2-8mm; mean, 5.1 +/-1.12) than in their asymptomatic heels(1.3-5mm; mean, 3.5 +/-0.78)(p<0.0001), inwhich it was similar to that of heels of patients in the control group(1.8-5mm; mean, 3.0 +/-0.71)(p<0.0001). Theproximal plantar fascia was hypoechoic in 31 symptomatic heels(91.2%), in four asymptomatic heels(15.4%), and innone of the patients in the control group. Calcaneal spurs were identified in sixteen symptomatic heels(47.1%),and in two which were asymptomatic(7.7%). Perifascial fluid collection was identified in only two symptomaticheels(5.9%). CONCLUSION: In plantar fasciitis, sonography demonstrates that the fascia is thicker as well ashypoechic. For the clinical diagnosis of planter fasciitis, US can therefore be used as an adjunct to clinicaldiagnosis.
