Brief summary

The goal of this observational cross sectionl study is to explore the correlation between Böhler angle and dynamic postural stability indices after calcaneal internal fixation. in calcaneal fracture post internal fixation both gender, (18-40) yr.

Detailed description

The goal of this observational cross sectionl study is to explore the correlation between Böhler angle and dynamic postural stability indices after calcaneal internal fixation. * To explore the correlation between Böhler angle and fall risk index after calcaneal internal fixation. * To explore the correlation between Gissane angle and dynamic postural stability indices after calcaneal internal fixation. * To explore the correlation between Gissane angle and fall risk index after calcaneal internal fixation. * To explore if Böhler angle can predict dynamic postural stability indices after calcaneal internal fixation. * To explore if Böhler angle can predict fall risk index after calcaneal internal fixation. * To explore if Gissane angle can predict dynamic postural stability indices after calcaneal internal fixation. * To explore if Gissane angle can predict fall risk index after explore in calcaneal fracture post internal fixation both gender, (18-40) yr, The main questions it aims to answer are: • Will there be a significant correlation between Böhler angle and dynamic postural stability indices after calcaneal internal fixation? * Will there be a significant correlation between Böhler angle and fall risk index after calcaneal internal fixation? * Will there be a significant correlation between Gissane angle and dynamic postural stability indices after calcaneal internal fixation? * Will there be a significant correlation between Gissane angle and fall risk index after calcaneal internal fixation? * Will Böhler angle can significantly predict dynamic postural stability indices after calcaneal internal fixation? * Will Böhler angle can significantly predict fall risk index after calcaneal internal fixation? * Will Gissane angle can significantly predict dynamic postural stability indices after calcaneal internal fixation? * Will Gissane angle can significantly predict fall risk index after calcaneal internal fixation?
