Evans Osteotomy / Lateral Column Lengthening (LCL)
Evans Osteotomy / Lateral Column Lengthening (LCL)
In lateral column lengthening or Evans osteotomy procedures for flatfoot correction, a bone wedge can be inserted into a cut in the calcaneus to create a gap for foot realignment. This bone wedge is secured with screws or plates to maintain the new alignment and integrate with the surrounding bone over time. The use of a bone wedge allows the surgeon to control the amount of correction precisely.
- This study compared the outcomes of using iliac tricortical autograft versus allograft supplemented with platelet rich plasma (PRP) in lateral column lengthening procedures. Iliac tricortical allograft supplemented with PRP demonstrated superior outcomes compared to iliac tricortical autograft.
- This study evaluated the effectiveness of using autograft versus allograft bone in lateral column lengthening (LCL) procedures. Over a three-year period, the research analyzed 126 LCLs performed on 120 patients and found that failure rates were not significantly different between autograft and allograft methods.
- The study reviewed medical records of 51 patients who underwent anterior calcaneal osteotomy (ACO) with allogenic bone graft for flatfoot deformity, with an objective to understand the outcomes associated with the use of allograft. The findings suggest that ACO with allogenic bone graft is a viable alternative to autograft for the treatment of flexible flatfoot in both adolescent and adult patients.
