There is limited information regarding the use of temporary hemiepiphysiodesis for Blount disease. We performed a systematic review of patients treated for Blount disease using either extraperiosteal staples or plates to identify characteristics affecting clinical outcome, including the need for unplanned procedures. A total of 53 patients (63 bone segments) underwent temporary hemiepiphysiodesis at a mean age of 8.8 years (1.8–14.7 years). Overall, 32/63 (51%) segments achieved neutral mechanical axis and 31/63 (49%) underwent unplanned subsequent procedures, with or without a subsequent osteotomy. On the basis of the available heterogeneous data, neither age at index surgery nor the type of implant correlated with the need for unplanned additional surgeries.
