Osteomyoplastic Transtibial Amputation: The Ertl Technique

Area of Science:

• Orthopedic Surgery
• Reconstructive Surgery

Background:

• Lower extremity amputations are necessary for trauma, neoplasm, infection, and vascular compromise.
• The Ertl technique is an osteomyoplastic procedure for transtibial amputation, aiming for a functional residual limb.
• A key feature is the tibiofibular bone bridge, potentially enabling distal weight bearing.

Purpose of the Study:

• To review the Ertl osteomyoplastic transtibial amputation technique.
• To highlight the importance of the tibiofibular bone bridge for residual limb function.
• To identify the need for comparative research on modified Ertl techniques.

Main Methods:

• Review of existing literature on the Ertl technique.
• Discussion of variations in modified Ertl techniques and fibular bridge fixation.
• Identification of current evidence gaps.

Main Results:

• The Ertl technique can create a stable, broad tibiofibular articulation.
• Various modifications and fixation methods exist for the fibular bridge.
• There is a lack of comparative studies on these different techniques.

Conclusions:

• The Ertl technique offers a method for creating a functional transtibial residual limb.
• Further research is required to compare different Ertl technique modifications.
• Optimal patient selection, surgical technique, and postoperative care need further elucidation.
