Treatment of Intercondylar Humeral Fractures With 3D-Printed Osteosynthesis Plates

View Article: PubMed Central - PubMed

ABSTRACT

The aim of the study was to evaluate the efficacy custom 3D-printed osteosynthesis plates in the treatment of intercondylar humeral fractures.

Thirteen patients with distal intercondylar humeral fractures were randomized to undergo surgery using either conventional plates (n = 7) or 3D-printed plates (n = 6) at our institution from March to October 2014. Both groups were compared in terms of operative time and elbow function at 6 month follow-up.

All patients were followed-up for a mean of 10.6 months (range: 6–13 months). The 3D-printing group had a significantly shorter mean operative time (70.6 ± 12.1 min) than the conventional plates group (92.3 ± 17.4 min). At the last follow-up period, there was no significant difference between groups in the rate of patients with good or excellent elbow function, although the 3D-printing group saw a slightly higher rate of good or excellent evaluations (83.1%) compared to the conventional group (71.4%).

Custom 3D printed osteosynthesis plates are safe and effective for the treatment of intercondylar humeral fractures and significantly reduce operative time.

Figure 3: The optimal site for plate implantation was determined using the 3D printed model.

Mentions: The 3D model of each patient's fractured elbow was slowly rotated to simulate the intraoperative reduction maneuver. The lateral and medial columns of the distal humerus were re-established. The carrying angle was restored to that of the contralateral side. Osteosynthesis plates with the proper size and number of holes were then fabricated using the 3D printer. The optimal implantation site of the printed plate was then determined using the models (Figure 3).
