Fig. 5

This figure shows the distance, parallel to the long axis of the humerus, from the medial base of the humeral head to the intersection of the median nerve and the proximal end of the underlying steel plate (a). The green areas indicate the safe area for screw placement (a and c). The blue arrow indicates the long head of the brachii tendon. Percutaneous screw fixation is not suitable between the distal and proximal incisions (b; the red areas)
