[Elastic stable intramedullary nailing as alternative therapy for the management of paediatric humeral shaft fractures].

AIM

We report about our experiences with the elastic stable intramedullary nailing (ESIN) of traumatic humeral shaft fractures in children and adolescents.

METHOD

Children with traumatic humerus shaft fractures who were treated by ESIN were included. All patients underwent clinical follow-up examinations.

RESULTS

31 children (average age 11.4 years) with traumatic humeral shaft fractures could be included. There were 14 oblique, 12 transverse and 5 wedge fractures. In 5 cases the fracture was located in the proximal third, in 22 cases in the middle third and in 4 cases in the distal third. After an average period of 32 months a follow-up-examination with the Constant-Murley score was performed. All children attained 100 points and all patients could take part in sports activities like before the accident. 30 children and their parents were very satisfied with the treatment success and 1 patient was satisfied. The following complications were seen: 1 postoperative damage of the radial nerve in a patient with secondary fracture dislocation (complete remission), 1 skin irritation, 1 fracture dislocation with axial deviation, 1 secondary dislocation of the nails after a second accident and 1 secondary axial deviation.

CONCLUSIONS

Elastic stable intramedullary nailing (ESIN) of humerus shaft fractures has a low complication rate if attention is paid to biomechanical principles. The observed complications are based on mistakes concerning the indication or technical errors. The ESIN shows very good functional and cosmetic results. It allows an early functional and cast-free follow-up with a quick pain reduction. The ESIN of humeral shaft fractures is a minimally invasive, simple and well reproducible technique with a steep learning curve. Because of the excellent objective and subjective results, the operative stabilization of humerus shaft fractures with ESIN should be recommended to the patients and their parents.
