Gauze Application of Phenol for Matrixectomy

Phenol matrixectomy is commonly used to treat onychocryptosis. The podiatric medical community has been progressively improving the technique of phenol application to avoid cases of burns. We describe a modification that uses gauze to provide a safe way for the phenol to be applied and prevents skin lesions due to phenol burns.

Clinical improvement in functional hallux limitus using a cut-out orthosis.

Background: Functional hallux limitus (FHL) has been implicated in the development of metatarsophalangeal joint osteoarthritis. Objectives: To determine whether cut-out orthosis treatment increases plantarflexion of the first metatarsal by increasing its declination angle. Study design: Cross-sectional study. Methods: A total of 46 female volunteers with an average age of 25.66 ± 5.70 years (range: 19–42 years) and FHL participated in the study. We assessed the degrees of movement of the first metatarsal and proximal phalanx bones at the first metatarsophalangeal joint without and while wearing the cut-out orthosis using the 3Space Fastrak® via sensors. Results: The movement of the plantarflexión declination angle of the first metatarsal bone was higher using the orthosis 29.84° ± 5.98° versus without orthosis 27.69° ± 5.91° (p < 0.031°). Use of sandals may have minimized the magnitude of movement changes associated with orthosis versus non-orthosis use. Conclusion: The cut-out orthosis demonstrated a beneficial effect on non-fixed first metatarsophalangeal and metatarsal cuneiform joints affected by FHL, significantly increasing the declination of the metatarsal angle. Furthermore, use of the cut-out orthosis significantly reduced adduction movement of the first metatarsal bone in the transverse plane.

Revisión bibliográfica sobre la técnica quirúrgica de fenol-alcohol en el tratamiento de la onicocriptosis

La onicocriptosis es una patologia ungueal comun que suele afectar al primer dedo del pie, que cursa con dolor y limitacion funcional, siendo la tecnica de fenol-alcohol una de las mas usadas, por sus buenos resultados funcionales y esteticos. El objetivo del presente estudio fue realizar una revision bibliografica sobre esta tecnica quirurgica para el tratamiento de la onicocriptosis, para plasmar la mejora en las diferentes variables estudiadas por los autores. La busqueda bibliografica se realizo en el portal cientifico Medline® (Pubmed) usando los descriptores “onychocryptosis”, “phenol”, “phenol alcohol” y “phenol matricectomy alcohol”. Despues de la aplicacion de los filtros seleccionados, se seleccionaron 14 articulos para hacer la revision. Tras analizar las variables, podemos destacar que hay una prevalencia notoria en el uso de fenol-alcohol frente a fenol; el tabaco pueden alterar el tiempo de cicatrizacion y el uso de antibioticos enmascarar los signos de la infeccion. Ademas con la buena praxis de la tecnica, se observan bajas tasas de recurrencia y el grado de dolor es de baja/media intensidad, lo que favorece una pronta incorporacion a las actividades de la vida diaria.
