Is open reduction necessary for pediatric T-condylar fractures of the humerus?

The aim of this study was to investigate the outcomes of closed reduction and percutaneous pinning (Kirschner wire fixation) as a less invasive method for the treatment of pediatric T-condylar fractures of the humerus compared with open reduction and pinning. Among pediatric patients who were diagnosed with T-condylar fractures of the humerus between 2010 and 2017, those who underwent closed reduction and percutaneous pinning were retrospectively evaluated. The surgical technique used was to restore joint alignment through closed reduction and then to insert a pin parallel to the joint surface to stabilize the intercondylar fracture. Then, the supracondylar fracture was fixed with crossed pins. At 1-year follow-up, rotation, angulation, and joint range of motion were evaluated. Patient satisfaction was assessed subjectively using the visual analogue scale. Early and late postoperative Baumann angles were measured. All patients were male, and the mean age was 10.8 ± 4.6 years. The mean follow-up duration was 16.5 ± 7.2 months, and the mean union duration was 7.4 ± 2.3 weeks. None of the patients had any rotational deformities, but two had 5° of varus, one had 5° of valgus, two had a flexion contracture of 10°, and one had a flexion contracture of 40°. The only complication observed was a pin-tract infection, which developed in one patient. The mean visual analogue scale score was 9.25 ± 1. In pediatric patients with T-condylar humerus fractures, closed reduction and percutaneous pinning may be a good alternative to open reduction and pinning, because it is less invasive and does not cause additional complications.
