Background:. In 1931, Gaenslen reported treatment of haematogenous calcaneal osteomyelitis through an incision on the sole of the heel, without the use of antibiotics. We have modified his approach to allow shorter healing times and early mobilisation in a modern series of cases. Method:. Sixteen patients with Cierny-Mader Stage IIIB chronic osteomyelitis were treated with split-heel incision, calcaneal osteotomy, radical excision, local antibiotics, direct skin closure and parenteral antibiotics. 4 patients had diabetic foot infection with neuropathy, 5 had infection after open injuries, 4 had haematogenous osteomyelitis and 3 had Grade 4 pressure ulceration with bone involvement. 14 had sinuses/ulcers and 12 had undergone previous surgery. Primary outcomes were eradication of infection, time to sinus/ulcer healing, mobility and need for modified shoes. Results:. Mean hospital stay was 19.2 days (7–44). 14 patients had no recurrence of infection at final follow-up (minimum 12 months; mean 53 months). Ulcers healed between 4 and 15 weeks. 2 patients with recurrent infection required amputation. Of the 14 salvaged patients, 10 mobilised unaided. 9 required modified shoes. Conclusion:. This protocol gave effective control of infection, ulcer healing and mobilisation within an acceptable time, but amputation remains a risk

Between 2000 and 2006 we performed salvage tibiotalar arthrodesis in 17 diabetic patients (17 ankles) with grossly unstable ankles caused by bimalleolar fractures complicated by Charcot neuro-arthropathy. There were ten women and seven men with a mean age of 61.6 years (57 to 69). A crossed-screw technique was used. Two screws were used in eight patients and three screws in nine. Additional graft from the malleoli was used in all patients. The mean follow-up was 26 months (12 to 48) and the mean time to union was 5.8 months (4 to 8). A stable ankle was achieved in 14 patients (82.4%), nine of whom had bony fusion and five had a stiff fibrous union. The results were significantly better in underweight patients, in those in whom surgery had been performed three to six months after the onset of acute Charcot arthropathy, in those who had received anti-resorptive medication during the acute stage, in those without extensive peripheral neuropathy, and in those with adequate peripheral oxygen saturation (> 95%). The arthrodesis failed because of avascular necrosis of the talus in only three patients (17.6%), who developed grossly unstable, ulcerated hindfeet, and required below-knee amputation.
