Abstract

Purpose
This study analyzed the prognostic factors in patients with femoral head fractures by comparing two groups with and without complications.
Materials and Methods
A retrospective study was performed on femoral head fracture patients who visited two different level-1 trauma centers from January 1, 2014 to June 30, 2018. Thirty-three patients with a follow-up period of more than one year were included. Early complications were defined as fair or poor in the Thompson–Epstein clinical evaluation criteria and grades 3 or 4 in the Kellgren– Lawrence classification within one year after the fracture. The patients were divided into two groups, with and without early complications. Statistical analysis was performed for the nominal variables with a Fisher’s exact test and continuous variables using a Mann–Whitney U test.
Results
Nine patients (27.3%) had early complications, and there were no significant differences according to age, sex, treatment method, combined fractures, Pipkin classification, and AO/OTA classification between the two groups.
Conclusion
The prognosis in femoral head fractures is difficult to predict. Therefore, the validation of existing classifications or a new classification is necessary.
