Thickness of pronator quadratus fat pad complex(PQC) was measured using lateral views(CR) and sagittal reconstructions(CT). Pearson's test was used to determine the correlation of the PQC thickness in CR and CT. A positive pronator quadratus sign(PQS) was defined as a PQC > 8.0 mm(female) or > 9.0 mm(male). Frykman classification was utilized to assess the severity of fractures.RESULTS Forty-four/89 patients(49%) had a distal radius fracture(Frykman Ⅰ n = 3, Ⅱ n = 0, Ⅲ n = 10, Ⅳ n = 5, Ⅴ n = 2, Ⅵ n = 2, Ⅶ n = 9, Ⅷ n = 13). Mean thickness of the PQC thickness can reliably be measured on X-ray views and was 7.5 ± 2.8 mm in lateral views(CR), respectively 9.4 ± 3.0 mm in sagittal reconstructions(CT), resulting in a significant correlation coefficientof 0.795. A positive PQS at CR was present in 21/44 patients(48%) with distal radius fracture and in 2/45 patients(4%) without distal radius fracture, resulting in a specificity of 96% and a sensitivity of 48% for the detection of distal radius fractures. There was no correlation between thickness of the PQC and severity of distal radius fractures.CONCLUSION A positive PQS shows high specificity but low sensitivity for detection of distal radius fractures. The PQC thickness cannot predict the severity of distal radius fractures.展开更多
