Rate and Location of Reulceration and Reamputation After Partial First-Ray Amputation versus Hallux Amputation in Diabetic and Nondiabetic Populations

Background: We sought to determine the rates of reulceration and reamputation in individuals who underwent partial first -ray amputations versus hallux amputations in diabetic and nondiabetic populations. Methods: Eighty-four amputations were reviewed in a retrospective fashion. A retrospective medical record review was performed to determine patients who underwent a hallux amputation, both partial and complete, and patients who underwent a partial first -ray amputation. Only patients from 2007 to 2019 were reviewed. The reulceration rate of hallux amputations was 61% compared with a partial first -ray amputation reulceration rate of 74%. Results: The reamputation rate of hallux amputation versus partial first -ray amputation was 43% versus 51%. At final follow-up, it was statistically significant that patients who underwent hallux amputation were more likely to be healed than those who underwent partial firstray amputation, regardless of reulceration or reamputation. In addition, patients who underwent hallux amputation went on to digital amputation, and those who underwent partial firstray amputation went on to transmetatarsal amputation. Conclusions: Comparing partial first -ray amputation to hallux amputation, hallux amputation patients are more prone to subsequent digital ulceration. Patients who initially undergo hallux amputation have variable subsequent amputations, often digital. Reulceration primarily occurs at the incision site for partial first -ray amputations, with a higher likelihood of subsequent transmetatarsal amputation. Patients with a medical history of diabetes and staged procedures are more likely to receive partial first -ray amputations. However, hallux amputation patients have a lower risk of reulceration and reamputation, regardless of subsequent events. These findings underscore the importance of discussing risks and preventive measures with patients undergoing such amputations, emphasizing postoperative examinations for specific areas of concern. Hallux amputation appears to offer greater protection against reulceration and reamputation for both diabetic and nondiabetic populations. (J Am Podiatr Med Assoc 114(2), 2024; doi:10.7547/22-029)
