Thus, we aimed to evaluate this radiological deterioration and its association with mid-term functional follow-up.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Patients and methods<\/jats:title>\n<jats:p>We retrospectively reviewed 66 patients (mean age at fracture 53\u00a0years, SD 14.1, range 18\u201373, female 65%) with 68 C-type distal radius fractures at a mean of 6.7\u00a0years (SD 0.5\u00a0years, range 5.8\u20137.7\u00a0years) after primary closed reduction and cast immobilization. Radiographs of the wrists were taken and analysed for any radial shortening, dorsal tilt or step-off at the joint surface. Range of motion and grip strength were measured. In addition to the radiological result, primary outcome measures included Quick Disabilities of the Arm, Shoulder and Hand (QDash) and Patient-Rated Wrist Evaluation (PRWE).<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>At mid-term follow-up, an acceptable anatomical radiological result was seen in only 22 wrists (32%). Deterioration of the once-achieved and accepted primary alignment was seen in a majority of cases (68%). Radial shortening of \u2265\u20092\u00a0mm was found in 34 wrists (51%, mean 4\u00a0mm, range 2\u20138\u00a0mm), with no association with QDash (12.8 vs. 5.5, <jats:italic>p<\/jats:italic>\u2009=\u20090.22) or PRWE (9.1 vs. 5.7, <jats:italic>p<\/jats:italic>\u2009=\u20090.40). Only four patients (6%) showed step-off at the joint surface (mean 1.1\u00a0mm, range 0.5\u20132\u00a0mm). Twenty-two wrists (32%) showed dorsal tilt of \u2265\u200910\u00b0 (five with volar tilt of 15\u00b0\u201325\u00b0), with no effect on QDash or PRWE (14.7 vs. 6.5, <jats:italic>p<\/jats:italic>\u2009=\u20090.241 and 10.1 vs. 5.8, <jats:italic>p<\/jats:italic>\u2009=\u20090.226). Altogether, patients with dorsal tilt, step-off or shortening did not show significantly worse QDash (10.3 vs. 5.7, <jats:italic>p<\/jats:italic>\u2009=\u20090.213) or PRWE (8.1 vs. 5.1, <jats:italic>p<\/jats:italic>\u2009=\u20090.126) versus those with none. Twenty-nine (43%) of the patients had deficits in range of motion (ROM), either in extension (39%), flexion (43%), supination (16%) or pronation (4%), or combinations of these. Worse extension was associated with worse QDash (15.9 vs. 5.0, <jats:italic>p<\/jats:italic>\u2009=\u20090.037), flexion deficit with worse PRWE (11.5 vs. 4.4, <jats:italic>p<\/jats:italic>\u2009=\u20090.005) and supination deficit with both QDash (21.7 vs. 6.8, <jats:italic>p<\/jats:italic>\u2009=\u20090.025) and PRWE (18.9 vs. 5.2, <jats:italic>p<\/jats:italic>\u2009=\u20090.007).<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The initially accepted radiological alignment of AO type-C radius fractures deteriorated in a majority of cases during conservative treatment.
