  • What are the main claims of the paper and how important are they?

    Authors do make a good teaching point that AVN should be considered as a differential diagnosis in the setting of coccydynia. 

  • Are these claims novel? If not, please specify papers that weaken the claims to the originality of this one.

    No. Rare but Well known entity, especially if you take into account previous hx of steroids usage & AVN. 

  • Are the claims properly placed in the context of the previous literature?


  • Do the results support the claims? If not, what other evidence is required?

    nope. Index patient had coccydynia but not AVN. 

  • If a protocol is provided, for example for a randomized controlled trial, are there any important deviations from it? If so, have the authors explained adequately why the deviations occurred?

    Not applicable. 

  • Is the methodology valid? Does the paper offer enough details of its methodology that its experiments or its analyses could be reproduced?
