RESUMO
Background: Hyperkeratoses are thickenings of the stratum corneum, provoked by deviation of the ray and excessive plantar pressures. They are very common under the first metatarsal head (MTH) and on the big toe when there exists hallux valgus. The objective of this study was to assess plantar pressures pre- and post-surgery to try to define the threshold values that could determine the appearance of keratopathies. Materials and methods: Seventy-nine patients (100 feet) who had undergone percutaneous distal soft-tissue release and the Akin procedure were evaluated prospectively. The BioFoot/IBV® in-shoe system was used for objective baropodometric functional evaluations of the heel, midfoot, first through fifth MTHs, hallux, and lesser toes. The presence or absence of a hyperkeratosis (HK) or plantar callus under the first MTH or hallux was recorded. The average follow-up time at which the measurements were repeated was 28.1 months. Results: Pre-surgery, 62 feet presented a painful HK on the big toe, while post-surgery, only 9 of the feet presented the same lesion. Patients who presented a prior HK at the first metatarsophalangeal (MTP) joint had a mean pressure of 417.2 ± 254.5 kPa as against a value of 359.6 ± 185.1 kPa for the rest. Post-surgery, these values dropped to 409.8 and 346.3 kPa, respectively. Conclusion: Patients with HK presented an 11% greater mean pressure than those without. The values obtained with the BioFoot/IBV® system in the present study can therefore be considered predictive of the appearance of HK under the first MTH and on the side of the big toe.
RESUMO
Todos los seres vivos se encuentran bajo la influencia de un campo magnético. Por esta afirmación han sido utilizados los dispositivos magnéticos en diversas patologías para aliviar la sintomatología. El objetivo del estudio es realizar una revisión de la literatura publicada acerca del tratamiento de diversas patologías mediante el uso de dispositivos imantados, principalmente el de los soportes plantares. Se diseña una encuesta (N=60) acerca del conocimiento poblacional sobre estos dispositivos. Los resultados obtenidos en las encuestas demuestran un escaso conocimiento de los dispositivos y poca creencia en los mismos. La revisión de la literatura pone de manifiesto que este tipo de tratamiento con imanes posee un gran componente placebo(AU)
All living beings are under the influence of a magnetic field. By this statement the magnetic devices in various pathologies have been used to relieve the symptoms. The objective of the study is to conduct a review of published literature on the treatment of various diseases using magnetic devices, mainly of magnetic insoles. Designing a survey (N = 60) of population knowledge on these devices. The results obtained in the surveys show a little knowledge of devices and little belief in them. The literature review shows that this type of treatment with magnets has a large placebo component(AU)
