OBJECTIVESTo investigate the clinical features of femoral neck fractures and analyze related causes.

METHODSThe clinical data of patients with femoral neck fractures from June 2002 to August 2009 were retrospectively analyzed. The gender, age, fracture side, fracture type, basic social data, activities before injury, injury causes and treatment were analyzed.

RESULTSA total of 219 patients (106 male and 113 female) was analyzed. All patients were divided into children group (age < 16 years), adult group (age ranged from 16 to 60 years) and older group (> 60 years). There were 5 patients (2.3%) in the children group, 81 patients (37.0%) in the adult group and 133 patients (60.7%) in the older group. There were 11 patients (5.0%) with Garden I fractures, 32 patients (14.6%) with Garden II fractures, 90 patients (41.1%) with Garden III fractures and 86 patients (39.3%) with Garden IV fractures. Fall damage and traffic injury were the main injury types. Home and public place were the main injury sites.

CONCLUSIONSThe incidence of femoral neck fracture shows the highest in the old persons. The male patients with femoral neck fractures are more than female patients in children and adult group, while the male patients with femoral neck fractures are less than female patients in older group. The dominant fractures type according to Garden classification is Garden III fractures in children and adult groups, but Garden IV fractures in older group. Fall damage and traffic injury are the main injury types. Home and public place are the main injury sites.
