Amputation of the Distal Portion of the Foot

Therapeutic Footwear Can Reduce Plantar Pressures in Patients With Diabetes and Transmetatarsal Amputation

“…P atients with transmetatarsal amputation (TMA) are at high risk for skin breakdown and higher amputation. Multiple studies indicate that skin breakdown, wound failure, or higher amputation can arise in 17-44% of patients with TMA, with an average rate of ~30% (1)(2)(3)(4)(5)(6).…”

Minor amputations on the feet after revascularization for gangrene: A consecutive series of 95 limbs

“…Gianfortune et al (1985) found a success rate after ray resections of only one third. Healing rates of about 50% after transmetatarsal amputations have recently been reported (Hodge et al 1989, Hobson et al 1990). Hobson et al (1990) observed that even functioning femoropopliteal grafts did not improve the results.…”

“…When the grafts remained open, the success rate was 83% which was similar to our observations. Failed healing together with an adequate blood supply occurs in about 15-30% (Boeckstyns and Jensen 1984, Holstein 1984, Hodge et al 1989, Hobson et al 1990, Larsson et al 1993. The reasons may be infection (Holstein 1984) and probably wound breakdown on early weight bearing.…”

Re‐amputation occurrence in the diabetic population in South Wales, UK

“…skin breakdown and wound failure) or higher amputation following foot amputations (e.g. transmetatarsal amputations) among diabetic people might explain the lower incidence (23–29). In addition, the diabetic patients with partial foot amputations are predisposed to increased foot pressures and the development of foot deformities, consequently increasing their risk for ulceration and amputation (30).…”
