Introduction: Arthrodesis of the tibiotalar and subtalar joints is a salvage procedure that has been used successfully for years. Treatment options include internal procedures and external procedures. Retrograde intramedullary nailing is considered a safe procedure with a high degree of stability and comfort. Nevertheless, there are cases in which this internal arthrodesis fails and another procedure must be considered. Ilizarov fixator treatment could be a solution for those patients in whom intramedullary nailing has failed. Even if it means another surgical revision - is it possible to finally achieve consolidation with this method?, Materials and Methods: In this single-center, retrospective study all documents of patients who underwent tibiotalar and subtalar joints fusion using the Ilizarov external fixator at our institution from 2003 to 2023 as secondary treatment after frustrated first arthrodesis using an intramedullary nail were reviewed. Nineteen patients (17 men and 2 women), with an average age of 55.7 (standard deviation (SD) 8.7, range 34-75) years were included., Results: On average, 1.7 (SD 1.3, range 1-6) arthrodesis attempt were performed before final Ilizarov fixator arthrodesis. The average time spent in the Ilizarov fixator was 19 (SD 4, range 14-29) weeks. In seven cases (36.8%), both the tibiotalar and subtalar joints received bony consolidation in the end., Conclusion: If patients have undergone fusion of the tibiotalar and subtalar joints with a retrograde nail and this fails, it is difficult to achieve complete consolidation in the further course. A further attempt at arthrodesis using an Ilizarov fixator is possible, but the overall results are also poor. This procedure must therefore be seen as a last resort before amputation., Competing Interests: Declarations.

Background: The role of illicit drug abuse in total joint arthroplasty is largely unknown and is likely underestimated. Patients with drug addictions often suffer from septic osteoarthritis or a necrosis of the femoral head. Purpose of the study was to evaluate the operative management and clinical outcome of total hip replacement in patients with a history of intravenous drug abuse., Methods: This retrospective study included 15 patients with a history of intravenous drug abuse who underwent total hip arthroplasty. A total of 6 females and 9 males with an average age of 34.3 years were identified. Ten patients presented an acute bacterial coxitis (Coxitis-group) and five an aseptic osteonecrosis of the femoral head (Osteonecrosis-group)., Results: Ten patients with a bacterial coxitis underwent a two-staged total hip arthroplasty (THA), with temporary insertion of a drug-eluting spacer. Five patients with a necrosis of the femoral head were primarily treated with THA. All patients developed multiple re-infections after insertion of a drug-eluting spacer or THA. Only two patients finally achieved a THA without infection in the period of 3.9 years follow-up. The other 13 patients underwent a Girdlestone arthroplasty (7 patients) or total joint replacement with a chronic fistula (6 patients)., Conclusion: THA in patients with illicit drug abuse shows a low success rate. Following septic osteoarthritis or osteonecrosis in drug-addicted patients, we recommend a two-stage procedure with temporary insertion of a drug-eluting spacer. THA might follow only under strict premises.
