| description | Background: Calcaneonavicular (CNC) and talocalcaneal (TCC) coalitions are the most common cause of rigid flatfoot in children. After resection, correction of the most frequent valgus-hindfoot deformity usually requires a second-step surgery. We report results of a retrospective study of patients treated with a one-step correction. Methods: Between 2008 and 2019, data were collected on 26 patients (19 male, 7 female) affected by CNC (n = 18) and TCC (n = 13), all with rigid symptomatic flatfeet. Average age at surgery was 12.5 ± 1.1 (SD) years (range, 9.8-15.2). All patients (26/26) underwent resection, 20 of 26 underwent at the same time subtalar extraarticular screw arthroereisis (SESA) for correction of residual hindfoot valgus deformity. Pre- and postoperative talocalcaneal angle according to Costa Bartani and Talar inclination angle in weightbearing were measured. Twenty-five of 26 patients had postoperative American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score. Results: Pre- and postoperative talocalcaneal average angle for CNC was respectively 141.5 ± 7.7 degrees and 130.5 ± 5.2 degrees ( P < .0001) and 143.7 ± 7.7 degrees and 129.7 ± 7.0 degrees ( P < .0001) for TCC. Talar inclination average angle for CNC was 29.2 ± 5.3 degrees and 19.3 ± 1.6 degrees ( P < .0001) and 31.2 ± 6.4 degrees and 21.4 ± 3.4 degrees ( P < .0001) for TCC. Average follow-up (FU) was 4.7 ± 3.0 years (range, 6 months–11.9 years, median 4.9 years), with a mean age at FU of 17.2 ± 5.8 (SD) years (min 12.1, max 25.3, median 16.8 years). The mean AOFAS ankle-hindfoot score for CNC and for TCC was 96.6 (range 83-100) for resection and valgus correction as one-step procedure with no statistical difference ( P = .5) between CNC and TCC. No patients had additional surgery for complications or recurrence. Conclusion: Symptomatic rigid flatfeet affected by CNC and TCC treated with coalition resection and minimally invasive subtalar arthroereisis (SESA) for residual hindfoot valgus correction in one step in adolescent age achieved good to excellent results in all cases. Further surgery to correct malalignment was avoided. Level of Evidence: Level IV, retrospective study. |
