Plain radiography and computed tomography (CT) images of the left elbow. Plain radiography revealed an avulsion fracture of the olecranon process (a, b). CT shows small, avulsed fragments with comminuted bone (c).

Plain radiography revealed an avulsion fracture of the left olecranon process (Figures 1(a) and 1(b)). Computed tomography revealed small, avulsed fragments with comminuted bone (Figure 1(c)).
Intraoperative images of the left elbow. The triceps brachii tendon (double asterisk) is continuous with the fracture fragment (asterisk) (a). Two suture anchors (arrowheads) were inserted into the ulna proximal to the fracture site (b). After passing the suture thread through the triceps brachii tendon, the fracture fragments and triceps were reduced and fixed together using the suture bridge technique (c).

The fracture fragments were temporarily flipped with the triceps brachii, and the fracture site was freshened (Figure 2(a)). We inserted two JuggerKnot  anchors (Zimmer Biomet, Warsaw, IN, USA) into the ulna, proximal to the fracture site (Figure 2(b)). With the elbow kept in the reduced position of 45  of flexion, we inserted two Quattro  Link Knotless anchors (Zimmer Biomet, Warsaw, IN, USA) into the ulna distal to the fracture site and fixed the dislocated bone fragments using the suture bridge technique (Figure 2(c)).
Plain radiography images of the left elbow after the osteosynthesis. Postoperative plain radiography images demonstrated that the avulsion fracture fragments were reduced (a, b).

Postoperative plain radiography demonstrated that the avulsion fracture fragments were reduced (Figure 3).
