Titanium elastic nailing can be used in 6 to 10 years old pediatric with Delbet IV femoral neck fractures

The purpose of this study was to analyze the outcomes of titanium elastic nail (TEN) for the children in 6 to 10 years old who sustained a Delbet IV femoral neck fracture.A total of 56 children aged 6 to 10 years old with Delbet IV femoral neck fracture treated with TEN or cannulated screw (SC) were identified at our hospital from January 2009 to December 2019. Of which 24 were treated with TEN, and 32 with SC. All of them were followed up for 1 year after operation, and the differences in operation time, intraoperative blood loss, hospitalization time, hip joint function, and complication between the 2 groups were compared. Harris and Ratliff hip score were used to evaluate the hip function.All 56 fractures united properly. No major complications were noted in both groups. The intraoperative blood loss and operation time in TEN group and SC group were (11.42 ± 3.41) mL, (19.66 ± 4.05) mL (P = .000) and (33.58 ± 7.89) min, (40.22 ± 7.48) min (P = .002), respectively. There was no significant statistical difference between hip regarding range of motion and femoral neck-shaft angle in both groups, as well as Harris and Ratliff hip score between the 2 groups.TEN represent safe and effective methods in the treatment of Delbet IV femoral neck fracture in 6 to 10 years old children. TEN internal fixation is a minimal invasive and simpler technique and suitable for young children of Delbet IV femoral neck fracture.
