“…Therefore, arthrodesis, which involves several procedures, including fusion of the joint, is currently the most suitable surgical treatment. [18]. For patients with bipartite navicular bone, there may be no suitable treatment other than arthrodesis of the medial column.…”

“…Reade et al demonstrated that isolated talonavicular arthrodesis was performed for Müller-Weiss disease of a 25-year-old female, and fusion of the talonavicular joint was confirmed four months postoperatively [ 17 ]. Kitaura et al showed that talonavicular arthrodesis and talonavicular-cuneiform arthrodesis were performed in two cases of Müller-Weiss disease; talonavicular-cuneiform arthrodesis achieved bone union, but talonavicular arthrodesis resulted in nonunion [ 18 ]. For patients with bipartite navicular bone, there may be no suitable treatment other than arthrodesis of the medial column.…”

The bipartite navicular bone is a relatively rare pathological condition in which the navicular bone is segmented. As a high nonunion rate in talonavicular arthrodesis of the foot has been reported, an effective fixation method is required to achieve bone union. A compression staple can provide a persistent strong compressive force on the bone surface, which is advantageous for arthrodesis, especially for the joints with a high incidence of nonunion. A 13-year-old boy presenting with left foot pain was diagnosed with bipartite navicular. Imaging of the left foot showed that the navicular bone was divided into two parts and flatfoot deformity. After the failure of conservative treatment, talonavicular arthrodesis was performed. The lateral fragment was removed, and the talar and medial fragments were fixed using a cannulated cancellous screw (CCS) (Ace Medical, El Segundo, CA, USA) and compression staple (DynaNite, 15 mm × 12 mm, Arthrex, Inc., Naples, USA) to correct the flatfoot. Bone union was achieved, and flatfoot improved. Thirteen months postoperatively, his symptoms disappeared, and all categories of the Self-Administered Foot Evaluation Questionnaire scored 100 points. Although the bipartite navicular bone has no established treatment due to its rareness, talonavicular arthrodesis using a combination of CCS and compression staple yields good shortterm clinical outcomes including good alignment.
