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.

Mentions: Operative time was significantly shorter in the 3D-printing group (70.6 ± 12.1 min) than in the conventional group (92.3 ± 17.4 min, P = 0.026). The mean time to bone union was 3.4 months. At the last follow-up period, bone union was seen in all patients (Figure 4). In the 3D-printing group, elbow function was scored as excellent in 3 patients, good in 2 patients, and fair in 1 patient. In the conventional group, elbow function was scored as excellent in 2 patients, good in 3 patients, fair in 1 patient, and poor in 1 patient. The 2 groups showed no significant difference in the rate of patients with excellent or good 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%). Unsurprisingly, the ranges of elbow flexion/extension and pronation/supination did not differ significantly between the 2 groups (P > 0.05, Table 1).
