Ab1380 ultrasonographic Changes of Plantar Fascia in Patients With Plantar Fasciitis Due to Acquired Flat Foot

Abstract

BackgroundPlantar fasciitis is a chronic degenerative process of the plantar fascia enthesis. It manifests by pain, predisposition to prolonged course and treatment resistance. In many cases, plantar fasciitis develops in patients with acquired flat feet. Taken into consideration above mentioned, the study of the plantar fascia changes in patients with acquired flat feet by sonography is relevant.ObjectivesTo investigate the quantitative and qualitative sonographic changes of the plantar fascia in the case of plantar fasciitis in patients with acquired flat foot.Methods190 patients with plantar fasciitis on the basis of acquired flat feet (133 females and 57 males). The average age of patients was 48 ± 0.97 years (18-81years). Unilateral pathology was noted in 117 patients and bilateral – in 73 patients. The average body mass index was 27.68±0.3. The average duration of pain syndrome was 101 ± 6.0 days (7-390 days). The pain syndrome lasted up from 1 to 6 months – in 152 patients, and more than 6 months – in 38 patients. The control group included 15 healthy volunteers (30 feet). Clinical radiological, sonographic, and statistical methods were used.ResultsThe main sonographic features were significant reduction in echogenicity, erased or missing fibrous pattern, fuzzy contour of the aponeurosis; and modified contour of the calcaneus; small focal hyperechogenicity points in enthesis were detected. Loci of vascularization were detected using power Doppler sonography. The average thickness of plantar fascia in the study group was 6,14±1,5 mm (2,3-7,7 mm) and in control group – 3,5±0,1 mm (2,5-4,4 mm).ConclusionSonographic signs of plantar fasciitis on the basis of acquired flat feet were changes in echogenicity and structure, changes in the contours of the cortical layer of enthesis and plantar fascia, the thickening of the enthesis of the plantar fascia of more than 4 mm.Disclosure of InterestsNone declared
