Objects: To establish the effectiveness of Keller’s arthroplasty combined with the opening wedge osteotomy of the first metatarsal base area (RAKO) on the plantar distribution of load during standing; to establish load duration and its mean value during each stance phase of the gait cycle to establish patients’ content with the performed surgery. Materials and methods: Patients, aged 65-75, suffering from severe hallux valgus were divided into two groups of 40. The first group was treated with Keller’s resection arthroplasty (RAK). The second group was treated with RAK combined with the opening wedge osteotomy of the first metatarsal base area. The patients were assessed before the surgery and a year after the surgery. The clinical assessment was carried out with AOFAS scoring system. Hallux valgus angle, first intermetatarsal angle (IMK 1.-2.), first metatarsal inclination angle, the extent of the proximal phalange resection, the angle between the first and fifth metatarsals (IMK 1.-5.), and the extent of the pseudoegsostosis resection, were all measured roentgenologically. Distribution of the plantar pressure over the standard regions was measured with static and dynamic pedobarography. Duration and the mean extent of the pressure for each phase of stance in the gait cycle were measured at the intervals of 0,1 second with the platform for baropodometric analysis, Baropodometro Elettronico. Results: regarding the patients treated with RAKO surgery method show that the mean value for the HV angle is 16° and for the IMK 1.-5. is 9°, while the mean 1 MT inclination decrease is 2°; these figures correspond to those of the healthy population. Such high figures of the above-mentioned parameters could not be reached with the RAK method. Attained anatomical changes were recorded with both static and dynamic pedobarography: with the RAKO method the load increased in the region area 3C, which corresponds to the first metatarsal, while the lateral region of the foot became unloaded. Gait analysis showed that the heel pressure, which would prolong until the end of the stance phase, decreased; pre-surgical figures, or RAK method, showed that the heel pressure lasted for 2/3 of the stance phase. Middle part of the foot loading period corresponds to the pre-surgical figures, but the extent of the load decreased for 50%. Loading period of the forefoot lasts longer when the RAKO method was performed. Increased loading during walking can also be noticed in the hallux area. Conclusion: We significantly corrected the deformity of the hallux and the forefoot by using the RAKO method. Static and dynamic pedobarography helped us prove statistically significant distribution changes concerning the extent and duration of the foot load during standing and the stance phase of the gait cycle. The results show function improvement the anterior part of the foot. Furthermore, patients' clinical score after the surgical procedure with the RAKO method was substantially improved.
