Fig. 3From: Humerus trochlear angle (HTa)—a possible alternative for Baumann angle in the reduction of supracondylar humerus fracturesThe upper panel showed AP view of a left supracondylar humerus fracture (Garland type III) in HTa group before and after reduction (a, b), and contralateral side (c); the Baumann angle of both sides were 72° vs. 68°. The lower panel illustrated the reduction and pinning process under fluoroscopy and arthrogram, indicating the HTa angle decreased from 96° to 84° (e, d, f) after reductionBack to article page
