Statistical analysis of femoral neck fractures based on 3053 cases

Abstract

Femoral neck fractures in 2289 women and 764 men (total 3053) from the years 1975-1977 in Stockholm County Council were retrospectively analyzed regarding social and demographic classification. Seventy-nine percent of the patients (2418 of 3053) were admitted directly from their homes, more commonly in central city areas (82%) than in rural areas (74%). Direct return home was possible in 36%, and 47% could return home after some weeks of institutionalized rehabilitation. There was no increase in fracture incidence found during the three-year period. More fractures occurred on Mondays and less on Sundays than during the rest of the week. The period of December through March showed the highest fracture rate. Diseases other than hip fractures were seen in approximately one-half (1492) of the patients. Internal fixation was performed in 2937 fractures, mainly with the von Bahr screws (1465 cases), Hessel/Nyström multiple pins (674 cases), Thornton nails (380 cases), or Rydell nails (224 cases). Primary hemiarthroplasties were performed in only 102 cases. The detailed analysis of this consecutive population-based femoral neck fracture material is intended as a base for more uniform treatment and rehabilitation of this group of resource-consuming patients.
