N2 - Objective: Recent literature on acute diabetic Charcot osteoarthropathy (CA) reports unusually long periods of off-loading. Data suggest that this might increase the re-currence rate. Subsequently we evaluated the influence of duration of off-loading on the risk of required re-casting. Research Design and Methods: In this retrospective consecutive series from 2000 to 2005, 56 people with diabetes and an acute Charcot foot were included. The inclusion criteria were an initial persistent temperature difference more than 2 °C between the two feet, oedema, and typical hot spots on a bone scintigram, radiology, and a typical clinical course. Treatment was off-loading in a removable cast and 2 crutches. In-door walking was allowed. Gradually augmented weight bearing was prescribed when the skin temperature difference had decreased to a level less than 2°C and edema had subsided. Re-casting was required for immediate exacerbation during re-load as well as for recurrence - defined as new swelling and skin temperature difference of more than 2°C in the same foot occurring after a stable interval of at least one month after full weight bearing. Results: The duration of off-loading for all patients was 141 ± 21 days (mean ± SD). Three patients (5%) were re-casted immediately for exacerbation after re-load and 7 patients (12 %) after recurrence of the CA. Duration of re-casting was 79 ± 44 days. The primary period of off-loading was not statistically significantly different for those not requiring versus those requiring re-casting: 142 ± 24 days compared to 134 ± 41 days. Neither were the differences in demographic data, metabolic regulation, BMI or localization of CA. Conclusions: Patients with risk of exacerbation or recurrence of CA could not be identified in the present study and there was no relation to the duration of off-loading. Nevertheless off-loading periods with immobilisation should be kept as short as possible, due to other side effects. This can be obtained by early gradual augmented re-loading.
