Reviewer 2 Report

This study explores pre-operative, intra-operative, and postoperative prognostic factors that affect ambulation at discharge time in geriatric patients with fragile femoral neck fractures.
The group with the Ability to self-weight bearing at discharge is four times bigger than the one unable to do so. The statistical analysis does not account for this size effect, and there are many inconsistencies. The paper needs significant improvement in scientific and English writing (for instance, the discussion is hard to follow and too long). 

Major comments:

There is a problem with some groups where the number of patients is pretty low ( under 6 ), and the test performed was not a nonparametric test.
For groups above 6, please test the distribution and use parametric or nonparametric tests accordingly.
For groups under 6, please use a nonparametric test.
Calculate the error possible, power, and the number of samples needed to reach significance. 
Provide supplemental files and add them to the discussion when appropriate.
Then, based on the new results, please re-arrange your discussion appropriately.
