Summary
The offset "V" bunionectomy effectively corrects hallux abducto valgus by addressing key angular deformities. This surgical technique reduces recurrence and offers satisfying outcomes for patients.
Area of Science:
- Orthopedic Surgery
- Podiatric Medicine
- Foot and Ankle Reconstruction
Background:
- Hallux abducto valgus (HAV) is a common foot deformity.
- Recurrence of HAV is often linked to postoperative deforming forces.
- Existing distal metatarsal procedures have limitations in fully correcting the deformity.
Purpose of the Study:
- To evaluate the efficacy of the offset
Main Methods:
- The offset "V" bunionectomy technique involves cortical screw and buried Kirschner wire fixation.
- This method allows for correction of increased intermetatarsal angle (IMA) and proximal articular set angle (PASA) deviations.
- Complete soft tissue release and repair facilitates sesamoidal apparatus repositioning.
Main Results:
- The offset "V" bunionectomy demonstrated significant correction of IMA and PASA.
- The procedure effectively eradicated postoperative deforming forces, reducing recurrence rates.
- Authors reported extremely satisfying results in approximately 500 procedures over 7 years.
- The need for more complex osteotomies (base or distal) has decreased with experience.
Conclusions:
- The offset "V" bunionectomy is a reliable and effective procedure for hallux abducto valgus correction.
- It addresses multiple components of the deformity, leading to reduced recurrence.
- The technique's applicability is expanding, being used in 90% of the authors' HAV patients.
