Overview

Introduction:
The authors carried out the analysis of the causes for re-operations after percutaneous osteosynthesis of supracondylar fractures of the humerus in children.

Materials and methods:
The authors evaluated the complications of osteosynthesis of supracondylar fractures in children hospitalized at the Clinic of Pediatric Surgery, University Hospital in Bratislava, for a 5-year period between 2007 and 2011. From the total number (395) of supracondylar fractures, 372 were treated as closed reduction and percutaneous transfixation.

Results:
32 (8.6%) of supracondylar fractures that were treated as closed reduction and osteosynthesis were indicated for re-operation – 8 times for signs of lesion n. ulnaris, 7 times for migration of Kirschner wires, 17 times for non-anatomical status or osteosynthesis failure. In case of lesions of nervus ulnaris, Kirschner wires were eliminated from the ulnar side and replaced either with intramedullary descendently introduced Kirschner wire to the ulnar condyle (the first option) or with three divergent Kirschner wires from radial side (the second option). In case of failed osteosynthesis, reosteosynthesis was performed using three Kirschner wires (two parallel or divergent from the radial side and one through the medial epicondyle).

Conclusion:
During the period monitored, the introduction of a differentiated approach in the treatment of supracondylar fractures of the humerus in children according to the type of fracture and the degree of displacement has significantly reduced the number of reoperations. Subsequently, it is important to notice that the decreased number of reosteosynthesis can be also assigned to the fact that the initial operation is not necessarily carried out as an urgent one (e.g. by a surgical team on night duty), but can be postponed and performed by an experienced traumatological team next day.
