Video Summary

The video discusses the effect of insertion trajectory on the compressive performance of intramedullary devices for subtalar arthrodesis. Subtalar arthrodesis is a procedure used to relieve hindfoot issues, but factors like smoking and obesity can decrease fusion outcomes. Static compression fixation devices like screws and plates often fail to maintain adequate joint compression, leading to complications. The video investigates the effectiveness of sustained dynamic compression devices compared to static compression devices in maintaining joint compression. The study finds that sustained dynamic compression devices provide significantly greater joint compressive forces regardless of insertion trajectory. These devices allow surgeons to choose the most appropriate approach for each patient while ensuring sufficient joint compression outcomes. The limitations of the study include the use of sawbone samples instead of cadaveric tissue. The findings support the use of sustained dynamic compression devices in subtalar arthrodesis procedures.
