Sir,
We read this article with interest. We were surprised at
the authors' statement, “In contrast to studies from North America, we used
different time criteria”. A delay of greater than 12 hours in the
treatment of supracondylar humeral fractures in children has been
previously examined by Gupta et al1 with similar conclusions.
The authors excluded a total of 85 patients. Even allowing for open
fractures (2%) and ipsilateral upper limb fractures (3%), eliminating such
a large number of patients due to incomplete data will have significantly
reduced the power of the study. This has not been considered by the authors
when drawing their conclusions. With a relatively small study sample, was it
reasonable to perform a parametric analysis of the data?
