Figures & data
Table 1. Monthly registrations of primary operations
Table 2. Baseline data for all patients according to fracture types. Fractures operated with a THA, and reported to the arthroplasty register, were classified as femoral neck fractures or trochanteric fractures without further subclassification. The p-values relate to statistically significant differences between fracture types
Table 3. Reporting completeness for different subgroups of the 11,038 patients who received the 4-month questionnaire
Table 4. Frequencies of fracture type and operation method in the 13,251 hips primarily operated for hip fractures. Fractures operated with a THA, and reported to the NAR, were classified as femoral neck fractures or trochanteric fractures without further subclassification
Table 5. Distribution of implants used in primary operated hip fractures
Table 6. Reason for reoperation. All reoperations after hip fracture surgery registered in the hip fracture register in 2005 and 2006, including reoperations with THAs reported to the arthroplasty register. The numbers also include reoperations with no registered index operation. Note that each reoperation may have more than one indication. The total number of reasons (2,619) is therefore higher than the total number of reoperated hips (2,325)
Table 7. Type of reoperation. The numbers also include reoperations with no registered index operation. Note that each reoperation could consist of more than one procedure. The total number of types of reoperations (2,421) is therefore higher than the total number of reoperated hips (2,325)
