An accessory navicular bone may cause pain due to continuous irritation at its interface with the navicular. The authors performed the fusion of the accessory navicular and navicular with screw(s) to relieve the symptoms while preserving the continuity of the posterior tibial tendon.
We analyzed the clinical and radiological outcomes of 31 consecutive patients (34 feet) with a painful type II accessory navicular.
Bone union was confirmed on plain radiography in 28 (82%) of 34 feet. Twenty-two patients (24 feet) were assessed as excellent, two (three feet) as good, and one (one foot) as fair. Nonunion developed in six patients (six feet) and was defined as poor.
When conservative treatment fails to relieve pain in a type II accessory navicular, fusion of the accessory navicular to the navicular may successfully relieve pain without disrupting the tibialis posterior tendon insertion.
副舟骨与其相邻的舟骨之间持续的摩擦可能会导致疼痛。作者采用螺钉将副舟骨与舟骨融合，以缓解症状，同时保留胫后肌腱的连续性。
我们分析了连续31例（34足）疼痛性II型副舟骨患者的临床和影像学结果。
34足中的28足（82%）在X线平片上证实骨愈合。22例患者（24足）评估为优，2例（3足）为良，1例（1足）为可。6例患者（6足）出现骨不连，定义为差。
当保守治疗无法缓解II型副舟骨疼痛时，将副舟骨与舟骨融合可成功缓解疼痛，且不破坏胫后肌腱附着点。
