What type of osteotomy is used in Koutsogiannis procedure?

• A. Medial displacement oblique
• B. Lateral displacement oblique
• C. Distal chevron
• D. Proximal crescentic

Answer: (A)

The Koutsogiannis procedure is specifically designed for correcting certain foot deformities, particularly flexible flatfoot or other types of hindfoot alignment issues. This surgical technique incorporates a medial displacement oblique osteotomy, which is characterized by performing an oblique cut in the bone that allows for the medial sliding or shifting of the bone fragment.

By using a medial displacement oblique osteotomy, the procedure facilitates realigning the talus in relation to the calcaneus to improve medial arch support and thus enhance the overall function of the foot. The strategic placement and angling of the cut allows for effective correction of the alignment by reorienting the weight-bearing axis of the foot, which is crucial in treating conditions that involve excessive pronation or flatfoot deformities.

This technique's focus on medial displacement is essential for achieving optimal biomechanical results, emphasizing the importance of the proper selection of osteotomy type based on specific anatomic and functional needs of the patient.
