Researchers conducted a small study with 99 adults who had Type 2 diabetes and a specific type of foot ulcer on the bottom of the foot. They wanted to see if a newer type of cast, called a posterior slab cast (PSC), worked as well as the standard total contact cast (TCC) for taking pressure off the wound to help it heal.
After six months, more wounds had healed in the group using the posterior slab cast (about 73%) compared to the group using the total contact cast (about 49%). Patients also reported being more satisfied with the newer cast. The study did not report any information about safety problems, side effects, or how easy the casts were to live with day-to-day.
The main reason to be careful is that this was a small, single-center study where both the patients and doctors knew which cast was being used. This can sometimes influence results. The findings are promising, but they need to be checked in larger, more rigorous studies that also look at safety and long-term outcomes. For now, this suggests the posterior slab cast could be a helpful alternative, but it is not yet proven to be the new standard of care.
