Summary
The lateral calcaneal lengthening osteotomy (LCLOT) effectively corrects painful flexible flatfoot (PCFD) in a single procedure. This review differentiates LCLOT from other calcaneal osteotomies, highlighting its successful outcomes.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Reconstruction
- Biomechanics
Background:
- Calcaneal osteotomies are standard for treating painful flexible Progressive Collapsing Foot Deformity (PCFD).
- The lateral calcaneal lengthening osteotomy (LCLOT) offers a single-incision approach for three-dimensional correction of PCFD.
Purpose of the Study:
- To review and differentiate various types of calcaneal lengthening osteotomies.
- To analyze the anatomical, biomechanical, and clinical aspects of LCLOT.
Main Methods:
- Comprehensive review of anatomical, biomechanical, and clinical studies.
- Comparative analysis of LCLOT against other calcaneal osteotomy techniques.
Main Results:
- LCLOT is distinct from Evans or Z-shaped osteotomies.
- Performed at the sinus tarsi, LCLOT corrects hindfoot valgus, foot abduction, and medial arch collapse via the subtalar joint axis.
- Technique variations exist in graft and fixation; LCLOT demonstrates high union rates and positive clinical results.
Conclusions:
- LCLOT is a highly effective single-site osteotomy for triplanar correction of flexible flatfoot/PCFD.
- It represents a powerful surgical option for complex foot deformities.
