Medial displacement calcaneal osteotomy using minimally invasive technique

Area of Science:

• Orthopedic Surgery
• Foot and Ankle Surgery
• Surgical Innovation

Background:

• Medial displacement calcaneal osteotomy is a key procedure for pes planovalgus deformity.
• Traditional approaches carry risks of wound complications, infection, and neurovascular injury.
• A minimally invasive technique is presented as an alternative approach.

Purpose of the Study:

• To describe and evaluate a minimally invasive technique for calcaneal osteotomy.
• To assess the learning curve and outcomes of this new surgical approach.
• To compare minimally invasive outcomes with traditional open methods.

Main Methods:

• Retrospective review of 30 sequential calcaneal osteotomies performed since 2011.
• Surgeries were conducted by two surgeons trained in a minimally invasive cadaveric approach.
• Cases included 29 for acquired flexible planovalgus deformity and 1 for malunited calcaneal fracture.

Main Results:

• 100% radiological and clinical union achieved in all 30 cases.
• No neurovascular or wound complications were reported.
• Restoration of neutral hindfoot alignment was observed in all patients.

Conclusions:

• Minimally invasive calcaneal osteotomy demonstrates excellent union rates and effective deformity correction.
• The technique showed no observed neurovascular or soft tissue complications.
• A short learning curve exists for surgeons experienced in open procedures.
