Abstract
Purpose
We compared the results of two types of implants, dynamic compression plates (DCPs) and locking compression plates (LCPs), applied to correct mid-distal third humeral shaft fractures using minimally invasive plating osteosynthesis (MIPO).
Methods
Data of 43 patients with mid-distal third humeral shaft fractures treated using MIPO were retrospectively analyzed. Patients were divided into two groups according to the implants applied: group A (n = 26), those whose fractures were fixed with 4.5-mm DCP, and group B (n = 17) fixed with 4.5-mm LCP or metaphyseal LCP. The outcomes of the two groups in terms of operative time, time of fracture union, occurrence of early and late postoperative complications, University of California—Los Angeles (UCLA) End-Result score and the Mayo Elbow Performance Index (MEPI) were compared.
Results
The mean operative time was 107.8 ± 33.1 min in group A and 91.2 ± 40.4 min in group B (p > 0.05). The mean time of fracture union was 16.77 ± 6.01 weeks in group A and 14.59 ± 5.73 weeks in group B (p > 0.05). Seven (26.9 %) patients had postoperative complications in group A and 3 (17.6 %) in group B (p > 0.05). The mean UCLA End-Result score in group A was 34.31 ± 1.26 points and 33.12 ± 2.76 points in group B (p > 0.05). The mean MEPI was 100.00 ± 0.00 points in group A and 97.35 ± 7.52 points in group B (p > 0.05).
Conclusions
In surgical stabilization of mid-distal humeral shaft fractures using MIPO, application of DCP or LCP resulted in good outcomes, there were no significant differences between the outcomes of these two types of implant.
