What procedure is indicated for a symptomatic flatfoot due to an accessory navicular?

• A. Kidner procedure
• B. Evans procedure
• C. Reconstructive surgery
• D. Arthrodesis

Answer: (A)

The Kidner procedure is specifically indicated for symptomatic flatfoot that arises from an accessory navicular bone. This procedure involves resection of the accessory navicular and is designed to relieve pain by addressing the underlying structural issue associated with the accessory navicular, which can create complications such as tendinitis or posterior tibial tendon dysfunction. In a patient presenting with symptomatic flatfoot due to this anatomical variation, the Kidner procedure not only alleviates discomfort but also aims to restore proper biomechanical function of the foot. The surgery may also include lengthening the tendon if there is tightness, thereby optimizing alignment and function. This procedure is particularly effective because it directly targets the cause of the symptoms. Other surgical options, such as the Evans procedure, focus more on lateral column lengthening for different forms of flatfoot deformities and are not specifically addressing the accessory navicular itself. Reconstructive surgery can be quite broad and would usually involve more complex interventions aimed at multiple deformities, while arthrodesis involves fusing bones together, which is generally reserved for severe cases or when more conservative methods have failed. Therefore, the Kidner procedure stands out as the most appropriate choice for this specific condition.
