The evaluation of pre- and post-operative classification system for cubital tunnel syndrome

Pre- and post-operative classification systems for cubital tunnel syndrome are discussed in this study. Although there are several pre-operative evaluations, a suitable system should be easy to categorise, simple, reliable and reproducible. McGowan's grading system has been widely used for these reasons; however, grade II included complicated cases. Accordingly, McGowan's grade II is divided into two groups, such as grade II-A (relatively good prognostic group) and group II-B (relatively poor prognostic group). As far as the post-operative classification system is concerned, 4 grade (excellent, good, fair, and poor) classification is the most useful and easy to understand.
