Purpose: We analyzed the Metatarso-Phalangeal Oblique Angle(MPOA) of Diabetic foot. Materials and methods: We studied retrospectively 60 cases of diabetic foot in 52 patients, for the evaluation of the correlations between clinical outcomes and radiologic findings in the conservative management group (Group A; 36 cases) and the major operation group (Group B; 24 cases). We measured MPOA on AP view. The MPOA was defined as the intersection angle of the Metatarso-Phalangeal Break Line (a line passing from the second to fifth metatarsal heads) and the long axis of foot in sagittal plane. We performed the statistical analysis between MPOA and clinical outcomes. by independent t-test. Results: The mean of MPOA in group B, $70.79^{circ}$ (range: $62.8^{circ}-81.3^{circ}$), was significantly higher than that in group A, $68.04^{circ}$ (range: $62.0^{circ}-76.4^{circ}$). The mean of MPOA in patients of fore foot lesions(30 cases), $71.30^{circ}$ (range: $62.0^{circ}-71.5^{circ}$), was significantly higher than that in patients of hind foot lesions(30 cases), $66.97^{circ}$(range: $62.8^{circ}-81.3^{circ}$). Conclusions: We recognized the MPOA might be useful simple parameter in assessing the diabetic foot.
