Abstract Objective To assess the therapeutic effect of modified Kinder surgery against type Ⅱ painful accessory navicular bones (PANBs) among grass-roots officers and soldiers.Methods The clinical data on 27 patients with type Ⅱ PANBs treated in Beijing Municipal Crops Hospital of PAP between July 2016 and June 2018 was retrospectively analyzed. All the patients were males aged 18 to 29, with an average age of (22.6±3.2) years. The duration of the disease ranged from 6 to 18 months, with an average of (8.6±2.4) months. PANBs occurred on the left side in 12 cases and on the right side in 15 cases, including 5 patients with mild flat feet. The modified Kinder surgery was adopted before the data before and after operation was collected. The orthotopic radiographs were used to measure the talonavicular coverage angle, the talar-second metatarsal angle. Lateral radiographs were used to measure the talar-first metatarsal angle (Meary angle) and the calcaneus inclination angle (Pitch angle). The effect of surgery was quantified with the visual analog scale (VAS) and the American Orthopaedic Foot and Ankle Surgery Association (AOFAS) Midfoot Score.Results In this study, 27 patients were followed up for 12 to 24 months, with an average of (10.7±4.2) months. There were no complications, such as infection, internal fixation failure or deep venous thrombosis of lower limbs. During the last follow-up, it was found that foot pain had disappeared in 21 cases of , and pain was significantly alleviated in 6 cases. The range of foot movement became normal in each of the cases. On average, the talonavicular coverage angle was reduced from 18.81°±2.66° preoperatively to 13.26°±3.02° during the last follow-up, and the difference was statistically significant (t=9.188, P<0.001). The talar-second metatarsal angle was reduced from 14.41°±2.41° to 7.07°±1.66°, and the difference was statistically significant (t=17.887,P<0.001). The Meary angle decreased from 3.07°±1.07° preoperatively to 2.81°±0.786°, but there was no significant difference (t=1.657, P=0.110). The Pitch angle increased from 20.89°±2.90° to 21.89°±1.94°, but with no significant difference (t=-1.997, P=0.056). The VAS pain score decreased from 6.15±1.03 to 1.52±0.94, and the difference was statistically significant (t=20.360, P<0.001). The AOFAS Midfoot Score improved from 47.19±5.31 to 86.67±4.38, and the difference was statistically significant (t=-31.939, P<0.001).Conclusions It is recommended that the modified Kinder surgery be used to treat type Ⅱ painful accessory navicular bones in grass-roots officers and soldiers, with obvious pain relief, fewer complications, and good efficacy.
