Falta de correlación entre artrosis plantar del primer metatarsiano y sesamoideos y dolor en pacientes intervenidos de hallux valgus / Lack of correlation between plantar arthrosis of the first metatarsal joint and sesamoids and pain in patients after hallux valgus surgery

Objetivos. Valorar la aparición de artrosis en la zona plantar de la primera articulación metatarsofalángica (primera MTTF) en pacientes operados de hallux valgus y correlacionarla con la existencia de dolor preoperatorio. Material y métodos. Se valoraron 28 pacientes a intervenir de hallux valgus mediante osteotomía en «Scarf». Se observó si presentaban dolor en la zona plantar de la primera MTTF (área de los sesamoideos) en la anamnesis y la exploración. Se buscaron signos radiográficos de artrosis metatarsofalángica y se midieron el PASA preoperatorio y el grado de desplazamiento del metatarsiano respecto al sesamoideo medial. En la intervención se observó el grado de artrosis de la cabeza del primer metatarsiano y se valoró por la escala ICRS. Resultados. Dieciocho pacientes no tenían dolor, 7 tenían dolor leve (EVA 1-3) y 3 moderado (EVA 4-6). Macroscópicamente todos los pacientes presentaban artrosis en la cara plantar del primer metatarsiano. En las radiografías solo 5 pacientes mostraban signos de artrosis metatarsofalángica. No hubo correlación significativa (p=0,44) entre dolor y artrosis plantar del primer metatarsiano. Se observó cierta relación entre aumento del PASA y mayor grado de artrosis, pero no se encontraron diferencias significativas (p=0,06). Se encontró una correlación débil, pero significativa (p=0,04) entre la edad de los pacientes y la artrosis del primer metatarsiano. Conclusión. La artrosis en la articulación de la cabeza del primer MTT con los sesamoideos no se corresponde con la existencia de síntomas o la intensidad del dolor en esa zona en pacientes con hallux valgus (AU)

Objectives. To determine the relationship between osteoarthritis in the plantar region of the first metatarsophalangeal joint of the foot and patient pain after hallux valgus surgery. Material and methods. A total of 28 patients undergoing hallux valgus surgery were examined. The patients were examined for pain in the plantar region of the metatarsophalangeal joint (sesamoid bones area), by looking into their medical records and by means of palpation during the physical exam. X-rays were taken to look for metatarsophalangeal arthritis, and PASA and sesamoid displacement were measured. During the surgical procedure, the metatarsal head was macroscopically assessed for arthritis according to the ICRS Score. Results. Of the 28 patients, 18 had no pain, 7 had mild pain (VAS 1-3) and 3 had moderate pain (VAS 4-6). Macroscopically, all the patients had some degree of plantar osteoarthritis. Only 5 patients had radiological signs of metatarsophalangeal arthritis. There was no correlation (P=.44) between pain and plantar osteoarthritis. There was a mild but non-significant correlation between PASA and osteoarthritis (P=.06). There was a weak but significant correlation between patient age and arthritis (P=.04). Conclusion. Osteoarthritis in the plantar aspect of the first metatarsal head does not correlate with patient symptoms or with pain intensity in patients undergoing hallux valgus surgery (AU)
