This is an interesting subject matter and shows an unusual aspect of a common case.

The quality of the writing however, needs some attention.

The reference style is inconsistant. Some references within the text include years, others do not. A combination  of names and numbers are used when one or other would surfice. The numbers of references are sometimes in rounded brackets other times in square brackets. A reference is made to the work of Chung but no mention of Chung is to be found in the reference list. Reference 6 is cited in the text as "Rotherman" and in the list as "Rothermel JE"

In the case description abbreviations have been used "H/O" has no explaination and is unnecessary. Later in the paragraph the same abbreviation is used but now in lower case, again unnecessary and inconsistant.

The radiographs provided do not appear to have been annonymised and the patients name is apparent, patient identifiable information should not have been published without some attempt to annonymise it.

Finally the point is made that slipped upper femoral epiphysis affects teenagers. The patient age is given as 22, with her endocrine history I think that adds to the unique nature of this case and could be emphasised further.

I have worked in trauma and orthopaedics for several years
