Outcome of Ray Resection as Definitive Treatment in Forefoot Infection or Ischemia: A Cohort Study.

Ray resection is frequently performed in cases of infection or ischemia, but the literature is scarce concerning its outcome as a definitive treatment. In this retrospective cohort study, we reviewed our cohort with transmetatarsal ray resection with a mean follow-up of 36.3 months. Reulcerations, transfer ulcers, and reamputations were determined. Risk factor analysis for revision surgery was conducted. Among 185 patients, 71 (38.4%) had revision surgery within a mean of 1.4 ± 2.6 years (range 2 days to 12.9 years), 22 (11.9%) had major amputations, 49 (26.5%) had minor amputations, 11 (5.9%) had same-ray reulceration, 40 (21.6%) had transfer ulceration, and 2 (1.1%) had both reulceration and transfer ulceration. Occurrence of a postoperative ulcer was statistically significantly associated with revision surgery (p < .01). In conclusion, metatarsal ray resection is a reasonable treatment option in cases of forefoot ischemia or infection to prevent major amputation but fails in 11.9%, and reulceration is associated with further revisions, making ulcer prevention paramount.
