Preferred screw placement area identified by imaging based quadrant and heatmap analysis for long screw fixation in Ogawa I coracoid process fractures.

ABSTRACT: Ogawa I coracoid process fractures are relatively rare. Surgical fixation requires precise determination of the screw length and direction to avoid iatrogenic injuries. Identifying the preferred screw placement area (PSPA) through imaging techniques is crucial for enhancing surgical safety and stability. This study utilized shoulder computed tomography (CT) data from 100 adult patients, employing three-dimensional (3D) modelling and simulated surgeries to analyze the PSPA for long screw fixation in Ogawa I coracoid process fractures. Scapular Y-view two-dimensional (2D) fluoroscopic images were divided into quadrants. Using scatter plots and heatmap techniques, we identified the PSPA, cautious screw placement area (CSPA), and danger screw placement area (DSPA). Preliminary validation was c
