Supramalleolar Osteotomy: Indications and Surgical Techniques

Area of Science:

• Orthopedic Surgery
• Biomechanics
• Podiatric Medicine

Background:

• Ankle arthritis often presents with asymmetric deformities (varus or valgus).
• Current treatments may not adequately address these specific deformities when significant joint surface remains.
• Supramalleolar osteotomies present a viable surgical option for specific cases.

Purpose of the Study:

• To outline the principles and application of supramalleolar osteotomies.
• To emphasize the importance of preoperative planning and patient selection.
• To evaluate the efficacy of this procedure in correcting ankle deformities.

Main Methods:

• Review of surgical principles for supramalleolar osteotomies.
• Analysis of preoperative planning requirements.
• Assessment of patient selection criteria for optimal outcomes.

Main Results:

• Supramalleolar osteotomies can effectively treat asymmetric ankle arthritis.
• Accurate preoperative planning is crucial for successful deformity correction.
• The procedure restores the lower leg's mechanical axis, redistributing joint forces.

Conclusions:

• Supramalleolar osteotomies are a valuable surgical option for select patients with ankle arthritis.
• Meticulous preoperative planning ensures successful execution and favorable outcomes.
• This technique offers a method for joint-sparing correction with a low complication rate.
