Oblique K-wire Control in Calcaneal Osteotomy for Flatfoot Correction

Adult-acquired flatfoot deformity (AAFD) often requires surgical correction when conservative methods fail. Calcaneal displacement osteotomy is a key procedure in restoring alignment. This study introduces a novel K-wire technique to enhance control during surgery and minimize complications related to manual manipulation. It builds on prior research highlighting the limitations of traditional approaches in achieving precise fragment positioning.

About this study

Flat foot deformity, particularly adult - acquired flatfoot (AAFD), often necessitates surgical intervention when conservative treatment fail. Calcaneal displacement osteotomy is a common surgical procedure for correcting calcaneal displacement and achieving stable fixation. The proposed K-wire technique offers a novel approach to improve control and reduce complications associated with manual manipulation during surgery. Previous studies have indicated challenges with traditional methods in achieving precise fragment control. This study aims to address these gaps.

  • Severe comorbidities or contradictions of the surgery

Treatment and study plan

oblique K-wire technique in controlling Calcaneal displacement during osteotomy in flatfoot correction

Procedure

Under spinal Anaesthesia , patients will placed in lateral decubitus position. A standard lateral incision will be made over the calcaneus, and the osteotomy site will be exposed. An oblique K-wire will be inserted percutaneously into the posterior calcaneus under fluoroscopic guidance to facilitate the desired displacement. Cannulated screws will then be inserted across the osteotomy site to secure the calcaneal fragment. Post-operative care will include a non-weight bearing protocol for six weeks, followed by gradual weight bearing as tolerated.

Primary outcomes
