Bilateral Naviculo-Medial Cuneiform Coalition: One Case Report / 대한정형외과학회잡지

ABSTRACT

We report one case of bilateral naviculo-medial cuneiform coalition in ten year old girl. She complained of pain in the medial aspect of the mid-foot related to long periods of standing and activity. Routine roentgenographs, specifically lateral views showed a bony bridge between the navicular bone and medial cuneiform. A biopsy revealed as fibrocartilaginous tissue. The bony bridge consists about one third in lateral view and 30 degree cephalad tilting in the antero-posterior view. Bilateral resection arthroplasty, with interposing flesh muscle fibers of the abductor hallucis, was performed for restoration of motion in the naviculo-medial cuneiform joint and relief of localized pain. Four months after surgery, pain around the mid-foot had almost complete subsided. One year postoperative, neither recurrence nor disability was observed. We will discuss the diagnosis and treatment of this rare case of bilateral naviculo-medial cuneiform coalition.
