From March 2016 to May 2019, a total of 221 adult patients with radial head fracture patients were included in consecutive studies and completed the 1\u2010year follow\u2010up. All patients were treated by unilateral arthroplasty. At each follow\u2010up visit, the visual analogue scale was used to measure patients' pain level. Occurrence of CRPS I, which was diagnosed by Budapest criteria, was the main outcome collected at baseline and the 1\u2010, 3\u2010, 6\u2010, and 9\u2010month follow\u2010ups. The baseline data were collected before surgery and included demographic and clinical data. Independent <jats:italic>t<\/jats:italic>\u2010tests and <jats:italic>\u03c7<\/jats:italic><jats:sup>2<\/jats:sup> tests were used as univariate analyses to compare the baseline data of patients with and without CRPS I.
