The previously established coronal medial and lateral, sagittal dorsal and posterior projections were used. Changes over time, correlations to the Dim\u00e9glio score, and the course of treatment were studied.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The medial malleolus\u2013navicular distance was shorter, while the talar tangent\u2013navicular distance and the talo-navicular angle were larger in clubfeet than in controls even after the initial correction. The healthy feet in unilateral cases did not differ significantly from the controls. The range of motion in the talo-navicular joint was approximately 20\u00b0 less in clubfeet than in controls during the first four years of life. The medial malleolus\u2013navicular distance ( r\u2009=\u2009\u20130.58) and the talo-navicular angle ( r\u2009=\u20090.66) at the first ultrasonography showed the highest correlation to the number of casts needed to correct the deformities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Ultrasonography can be used to evaluate the initial degree of deformities in clubfeet and to follow the progress of the treatment and growth. Ultrasonography showed a clear difference between clubfeet and controls during the first four years of life. Although it was not possible to define specific limit values as benchmarks in the treatment, dynamic ultrasonography can provide valuable support in the decision-making process when complementary treatment may be needed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of evidence:<\/jats:title>\n                    <jats:p>III<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/18632521231172548","type":"journal-article","created":{"date-parts":[[2023,5,17]],"date-time":"2023-05-17T06:38:13Z","timestamp":1684305493000},"page":"212-223","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["A four-year clinical and sonographic longitudinal follow-up of clubfeet treated according to Ponseti with normal references"],"prefix":"10.1177","volume":"17","author":[{"given":"G Arne","family":"Johansson","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden"},{"name":"Department of Orthopaedics, Region V\u00e4stra G\u00f6taland, Skaraborg Hospital, Sk\u00f6vde, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ylva B","family":"Aurell","sequence":"additional","affiliation":[{"name":"Department of Radiology, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden"},{"name":"Department of Diagnostic Radiology, Region V\u00e4stra G\u00f6taland, Sahlgrenska University Hospital, Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bertil H","family":"Romanus","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,5,17]]},"reference":[{"key":"bibr1-18632521231172548","volume-title":"Congenital clubfoot: fundamentals of treatment","author":"Ponseti IV.","year":"1996"},{"key":"bibr2-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1080\/17453670610013123"},{"key":"bibr3-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1097\/BPB.0000000000000525"},{"key":"bibr4-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0260336"},{"key":"bibr5-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-200207000-00019"},{"key":"bibr6-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-009-0720-2"},{"key":"bibr7-18632521231172548","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198062010-00004"},{"key":"bibr8-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1097\/BPO.0b013e318221eaa1"},{"key":"bibr9-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1097\/01.bpo.0000150814.56790.f9"},{"key":"bibr10-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-022-05039-9"},{"key":"bibr11-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000224062.39990.48"},{"key":"bibr12-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1097\/BPB.0000000000000321"},{"key":"bibr13-18632521231172548","doi-asserted-by":"publisher","DOI":"10.1053\/j.jfas.2022.01.024"},{"key":"bibr14-18632521231172548","unstructured":"Clinical practice guidelines for the management of clubfoot deformity using the ponseti method.
