This can cause flexor tendon ruptures. Herein, we conducted a cross\u2010sectional study and measured the ratio of teardrop height and the teardrop inclination angle as parameters of teardrop configuration for 200 standardized lateral radiographs (average age of the patients, 51 years). We also quantified the influence of the teardrop morphology by analyzing the fit of three locking plates to three radii with differing teardrop inclination angles using a three\u2010dimensional computer\u2010aided design system. The average ratios of the teardrop height and teardrop inclination angle were 0.42\u00b0 (0.30\u20130.56\u00b0) and 28.8\u00b0 (9.9\u201344.9\u00b0), respectively. The teardrop inclination angle was moderately correlated with age in men but not in women. In the plate\u2010to\u2010bone fit analyses, the fit of all the plates was significantly different between bones, with the configuration of the radius with the lowest teardrop inclination angle being the closest approximation to that of each plate. We demonstrated the interindividual variation in the shape of the teardrop and its influence on the fit of the volar plate, highlighting the importance of careful plate selection for achieving osteosynthesis of bones with a high teardrop inclination angle. \u00a9 2015 Orthopaedic Research Society.
