Abstract

Background Flexible flatfoot is a frequent deformity found in children. The aim of this study is to evaluate the pedographic outcome of the percutaneous arthroereisis with the use of a screw through the sinus tarsi into the talus. Materials and methods 43 calcaneo-stop procedures of 25 patients (18 bilateral, seven unilateral) were evaluated. Mean age at surgery was 10 years (7-14, SD 2.2) (SD: standard deviation), mean follow-up time was 9.7 months (3-19, SD 5.5). Patient satisfaction rate was recorded, the Meary's talus-Wrst metatarsal angle was measured with lateral radiograms, and a dynamic pedographic assessment was also performed. Results Patient satisfaction rate was excellent for 33 feet of 19 children, good for eight feet of Wve children, and poor for either feet of one child. We did not observe any complications during or following the surgery. The mean rest heel valgus decreased from 13.4° (10°-17°, SD 1.5) to 2.8° (0°-6°, SD 1.7) post op. The Meary's angle improved from 160.2° (148°-177°, SD 6.8) to 175.9° (167°-179°, SD 3.5). By pedographic analysis, the area and the pressure-time integral (load amount, PTI) values increased on the lateral regions of the sole (except for the lesser toes) and decreased on the medial areas (except for the hallux). The relative contact time in the lateral midfoot increased from 63.8% (39.6-78.4%, SD 10.6) to 75.1% (50-86.1%, SD 9.4), and that in the lateral forefoot region from 81.2% (60.4-89.2%, SD 6.6) to 86.8% (78.1-97.1%, SD 4.8). Conclusion The calcaneo-stop procedure is a simple and reliable method for the correction of severe flexible paediatric flatfoot. Our prospective, short-term results following the anterograde screw implantation into the talus correlate well with the results of similar or different arthroereisis methods. Further investigations are required to evaluate the long-term outcome of the screw calcaneo-stop method, including the conditions following implant removal.
