Researchers performed a study to assess the pedographic outcome of the percutaneous arthroereisis with the use of a screw through the sinus tarsi into the talus, through the evaluation of 43 calcaneo-stop procedures of 25 pediatric patients. Patient satisfaction rate was excellent for 33 feet of 19 children, good for eight feet of five children, and poor for either feet of one child. No complications during or following the surgery were observed. 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). 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).
