| Abstract |
This study compared the rates of mortality, medical complication, and reoperation after fixation surgery for displaced femoral neck fracture with those after hemiarthroplasty surgery for undisplaced femoral neck fracture using competing risk analysis in inpatients aged 60 years and above from a population database in Taiwan. We identified 13,772 subjects who underwent fixation for undisplaced cervical fracture and 13,772 matched controls who underwent hemiarthroplasty for displaced cervical fracture from 1998 to 2007, and followed them up until the end of 2009. The outcomes of patients who received internal fixation for undisplaced fracture and those of patients who received hemiarthroplasty for displaced fracture were compared. The 3-month, 2-year, and 10-year mortality rates were 4.9 %, 22.1 %, and 67.1 % for fixation, and 5.6 %, 23.8 %, and 71.0 % for hemiarthroplasty, respectively. The 3-month, 2-year, and 10-year cumulative incidence rates of the first reoperation were 7.4 %, 18.1 %, and 27.7 % for fixation and 6.3 %, 12.0 %, and 22.3 % for hemiarthroplasty, respectively. The 3-month cumulative incidence rates of the first medical complication were 14.4 % for fixation and 15.4 % for hemiarthroplasty, respectively. Hemiarthroplasty had a 1.09 times (95 % CI: 1.05-1.12) higher hazard ratio for overall death than fixation. However, fixation had a 1.36 times (95 % CI: 1.29-1.43) higher subdistribution hazard ratio for first reoperation than hemiarthroplasty after adjusting for gender, age, and comorbidities. The short-term overall mortality and medical complication rate of fixation for undisplaced fracture were slightly lower than those of hemiarthroplasty for displaced fracture. However, the short-term cumulative incidence of first reoperation after fixation was significantly higher than that for hemiarthroplasty. Further prospective studies or clinical trials based on the competing risk model, and which include important risk factors, are necessary to quantify the adjusted effects more precisely. |

Attention Score in Context
This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 May 2017.
All research outputs
#7,190,734
of 25,782,917 outputs
Outputs from BMC Musculoskeletal Disorders
#1,298
of 4,446 outputs
Outputs of similar age
#76,554
of 278,492 outputs
Outputs of similar age from BMC Musculoskeletal Disorders
#22
of 63 outputs
Altmetric has tracked 25,782,917 research outputs across all sources so far. This one has received more attention than most of these and is in the 71st percentile.
So far Altmetric has tracked 4,446 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.5. This one has gotten more attention than average, scoring higher than 70% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 278,492 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
