[Complications of 2 133 cases of pediatric long bone fracture undergoing elastic stable intramedullary nailing in a single medical center].

Objective

To summarize the clinical data of elastic stable intramedullary nailing(ESIN) in the treatment of long bone fracture of children in a single medical center, and to analyze the problems occurred after the ESIN surgery and corresponding solutions.

Methods

A retrospective analysis was conducted regarding the clinical data of 2 133 pediatric long bone fractures conforming to inclusion and exclusion criteria from June, 2005 to December, 2017 in Department of Orthopedics, Children's Hospital of Nanjing Medical University.There were 1 191 boys and 942 girls, aged from 23 months to 14 years with mean age of (5.7 ± 3.1)years.There were 1 866 cases treated with closed reduction with ESIN, while 267 cases were treated with small incision assisted reduction with ESIN.Postoperative problems have been statistically analyzed.

Results

There were altogether 2 133 children, including 603 cases of femur, 311 cases of tibia, 8 cases of fibula, 219 cases of humerus, and 992 cases of ulna/radius.The postoperative complications mainly consist of 62 cases of needle tail irritation reaction, 21 cases of misalignments of fracture alignment, 11 cases of intramedullary nail deformity or angular deformity, 7 cases of limb shortening, 14 cases of limited joint activity, 4 cases of nerve injury, 2 cases of tendon injury, 14 cases of difficult nail removal, 4 cases of cortical cleavage, 8 cases of delayed union, 1 case of nonunion, 6 cases of varus/valgus deformity, 5 cases of epiphyseal injury, 6 cases of ESIN exposure, and 2 cases of metal debris of ESIN' end.

Conclusions

The complications of treatment for children with long bone fractures by ESIN cannot be ignored.To master the important biomechanical properties, to get familiar with the local anatomy and to avoid obvious technical errors can reduce the occurrence of postoperative complications.
