Yushan M, et al. - Researchers retrospectively investigated patients presented with recurrent and persistent cubital tunnel syndrome (CuTS) who were treated surgically with combination of revision neurolysis and ulnar groove plasty in order to assess clinical outcomes related to this procedure. Among 28 patients identified with recurrent and persistent CuTS after primary surgery, 21 patients (75%) completed this study; average age was 56 years; mean duration of symptoms was 17.24 months; and mean postoperative follow-up was 35.38 months. Perineural fibrosis with or without kink was identified to be the most common cause of recurrent and persistent CuTS; this accounted for 86.36%. Revision neurolysis and ulnar groove plasty led to improvement in McGowan grading, in Visual Analogue Scale and in 2-point discrimination test results. Patients satisfaction was 95.24% after revision neurolysis and ulnar groove plasty. These outcomes support revision neurolysis and ulnar groove plasty as the treatment of choice for recurrent or persistent cubital tunnel syndrome.
