PTA as the first choice revascularisation procedure is feasible, safe and effective for limb salvage in a high percentage of diabetic patients. Clinical restenosis was an infrequent event and PTA could successfully be repeated in most cases.

For select patients, external fixation proved to be a reasonable alternative to below-knee amputation.

The diabetic foot is a complication of diabetes affecting 15% of diabetics in their lives. It is associated to diabetic neuropathy and peripheral vascular disease and its incidence has increased. The ulceration is the initial cause of a dramatic process leading, if not correctly treated, to amputations. Both neuropathy, neuro-ischemia and infections have a role in determining healing or worsening of the lesions and 85% of all amputations in diabetic patients are preceded by a foot ulceration deteriorating to a severe gangrene or infection. The different causative agents and the different clinical presentations of diabetic foot ask a multidisciplinary approach in order to address treatments to the final goals, the prevention of the amputations and the maintenance of a functional foot able with weight-bearing ability. Many professional figures, diabetologists, surgeons (both general and vascular and orthopedics), interventional radiologists, infectious diseases specialists, specialized nurses, podiatrists, orthotic technicians, are called to apply their knowledges to the diabetic patients affected by diabetic foot in a virtuous circle leading to reach the goals, with the imperative action of the multidisciplinary team. The so organized center will allow both a correct and rapid diagnosis, the use in ambulatorial environments of modern tools, or the hospitalization in multitasking wards, in which all the complications and the necessary treatments are possible, both in emergencies or in elective way, considering both revascularizations and surgery.

OBJECTIVE -to evaluate the reulceration and reamputation rates in a cohort of diabetic patients following first ray amputation.RESEARCH DESIGN AND METHODS -We evaluated a cohort of 89 diabetic patients, 63 men and 26 women, who underwent first ray amputation in the period from January 2000 to December 2001. The first ray lesions were Wagner grade 2 in 3 patients, Wagner grade 3 in 47 patients, and Wagner grade 4 in 39 patients. Following surgical wound healing, all patients wore special footwear with rocker bottom soles and custom molded insoles and were put on an intensive secondary prevention program.RESULTS -The mean follow-up duration was 16.35 Ϯ 6.76 months (range 7-28). Fifteen patients developed new ulcerations, with 11 lesions occurring ipsilaterally and 4 contralaterally to the first ray amputation. In seven patients, the new lesion was treated and healed with dressing. Eight patients underwent a new surgical procedure: panmetatarsal head resection in four patients, toe amputation in two patients, a transmetatarsal amputation in one patient, and Lisfranc's amputation in one patient.CONCLUSIONS -In the population studied, the first ray amputation presented a lower reulceration and reamputation rate with respect to that reported in the literature. This finding should therefore be attributed to the follow-up program, which uses shoes with a rocker bottom sole and custom molded insoles and intensive ambulatory check-ups. Diabetes Care 26:1874 -1878, 2003I n diabetic subjects, reulcerations following first ray amputations are particularly frequent (1,2). Recently, Murdoch et al. (3) has stated how the natural history of first ray amputation is characterized by a reulceration and consequent reamputation rate of 60% at 10 months' follow-up; the number of patients undergoing above ankle amputation (17%) was particularly relevant in their study. No clear indication regarding the amputation level currently exists in the literature, and some authors indicate that a transmetatarsal amputation (TMA) could be the optimum amputation level when the first ray has to be amputated (4 -9). The aim of our study is to evaluate reulceration and reamputation rates in a cohort of diabetic patients who underwent first ray amputation and subsequent intensive ambulatory follow-up, as well as the institution of shoes with a rocker bottom sole and custom molded multilayered insoles. RESEARCH DESIGN AND METHODS -From January 2000 to December 2001, 89 diabetic patients requiring a first ray amputation were admitted to two centers specialized in the treatment of the diabetic foot.We define a first ray amputation as an amputation of the phalanxes and of at least part of the metatarsus; therefore, we excluded patients who solely underwent amputation of the phalanxes. Patients with history of previous amputation were also excluded.All patients underwent our protocol for the diagnosis of peripheral arterial occlusive disease and neuropathy (10). Our protocol for detection of peripheral arterial occlusive disease consists of the evaluation ...

Diabetic patients are at increased risk of developing foot ulcers which may cause bone infections associated with a high probability of both amputation and mortality. Therefore, prompt diagnosis and adequate treatment are of key importance. In our Diabetic Foot Unit, effective multidisciplinary treatment of osteomyelitis secondary to diabetes involves the application of a gentamicin-eluting calcium sulphate/hydroxyapatite bone graft substitute to fill residual bone voids after debridement. The data of all patients treated with the gentamicin-eluting calcium sulphate/hydroxyapatite bone graft substitute for diabetic foot infections with ulcer formation and osteomyelitis at metatarsals, calcaneus and hindfoot at our institute from July 2013 to September 2016 were retrospectively collected and evaluated. A total of 35 patients were included in this retrospective single-arm case series and were either continuously followed up for at least one year or until healing was confirmed. Nineteen lesions affected the distal row of tarsus/talus, ten the calcaneus and a further six were located at the metatarsals. While all of the metatarsal lesions had healed at 1-year follow-up, the healing rate in the hindfoot region was lower with 62.5% at the calcaneus and 72.2% at the distal tarsus and talus at 12 months, respectively. The overall cure rate for ulcerous bone infection was 81.3%. In two calcaneal lesions (25%) and two lesions of distal tarsus/talus (11.1%) amputation was considered clinically necessary. Promising results were achieved in the treatment of diabetic foot infections with soft tissue ulcers by a multidisciplinary approach involving extensive debridement followed by adequate dead space management with a resorbable gentamicin-eluting bone graft substitute.
