Flexible flatfoot treatment with arthroereisis: radiographic improvement and child health survey analysis.

This study was designed to ascertain if there was a statistically significant correction in the foot and to determine the overall health of a child after an arthroereisis procedure. Thirty-seven patients (67 feet) who had undergone Maxwell-Brancheau arthroereisis were retrospectively reviewed at an average of 18.4 months after surgery. The pre- and postoperative lateral talo-first metatarsal and talar declination and the anteroposterior talo-first metatarsal and talocalcaneal angles were measured by using an X-Caliper device (Eisenlohr Technologies, Davis, CA); significance was determined with a t test. Child health questionnaire answers were calculated and converted to a 0 to 100 scaled score and statistically compared with population norms by using a single-sample t test. The lateral radiographic average preoperative talo-first metatarsal and talar declination angles were 11.3 and 27.5, respectively, and were 3.7 and 21.9, respectively, postoperatively. The preoperative average anteroposterior talo-first metatarsal and talocalcaneal angles were 13.8 and 25.6, respectively, and were 6.4 and 19.4, respectively, postoperatively. The t test showed the postoperative angles had a statistically significant (P <.01) change from the preoperative angles. The results of the Child health questionnaire of our 34 pediatric patients (92%) showed scores in 3 domains (role emotional behavior, global behavior, parent time) that were better than population norms, and there was no difference in the remaining domains.
