Abstract
Background: Pediatric fractures of femoral neck are rare accounting for not more than
1% of all pediatric fractures. The ideal treatment option for such cases is still unclear
whether open reduction or closed reduction and internal fixation is better. Serious
complications can occur in the management of displaced femoral neck fractures in
children.
Aim: to assess the association between healing rate and incidence of AVN postoperative
between open reduction internal fixation (ORIF) and closed reduction internal fixation
(CRIF) for femoral neck fracture.
Methods: We searched five databases; PubMed, Scopus, Science Direct, Web of
Science, and Medline Plus. The applicable outcomes for meta-analysis were avascular
necrosis, coxa vara, or non-union. We extracted the data and performed the analysis using
RevMan file (Review Manager Version 5.3)
Results: In the included studies, 294 patients underwent ORIF procedures and 266
patients underwent CRIF procedures. We found that there was no statistically significant
difference between both groups regarding avascular necrosis outcome (RR = 0.84, [95%
confidence interval (CI) = 0.60, 1.18], P = 0.32). The data were homogeneous (P = 0.22,
I² = 27%). There was no statistically significant difference between both groups regarding
coxa vara (RR = 0.69, [95% CI = 0.30, 1.58], P = 0.38). The data were homogeneous (P
= 0.22, I² = 27%). Same was result was found regarding non-union (RR = 0.45, [95% CI
= 0.16, 1.14], P = 0.12). The data were homogeneous (P = 0.49, I² = 0%).
Conclusion: We found no difference between ORIF and CRIF in decreasing the risk of
avascular necrosis, coxa vara, and non-union. However, studying of the other factors is
needed to approve this result, and subgrouping the patients according to fracture type
should be studied to get the appropriate method for each type.
