[VASCULAR ANATOMICAL STUDY ON TIBIAL OSTEOTOMY LENGTHENING].
Summary
Optimal tibial osteotomy sites for leg lengthening are in the metaphyseal-diaphyseal region. Avoid the lower third of the tibia for safer surgical outcomes in tibial lengthening procedures.
Area of Science:
- Orthopedic Surgery
- Anatomy
- Biomechanics
Background:
- Accurate osteotomy site selection is crucial for successful leg lengthening and tibial slip procedures.
- Understanding the anatomical vascularity of the tibia is essential for preventing complications.
Purpose of the Study:
- To define the anatomical landmarks for optimal proximal and distal tibial osteotomy.
- To establish an osteotomy index for precise surgical planning in tibial lengthening.
Main Methods:
- Dissection and measurement of tibial and peroneal arteries in 10 adult leg specimens.
- Identification of reference points on the proximal and distal tibia for anatomical measurements.
- Calculation of the osteotomy index based on arterial-bone distances.
Main Results:
- Proximal tibial osteotomy sites were identified relative to the medial tibial plateau, tibial tuberosity, and fibular head.
- Distal tibial osteotomy sites were determined based on the malleoli and distal tibial articular surface.
- Osteotomy indices for proximal and distal tibia ranged from 18.45-23.35 and 14.36-23.05, respectively.
Conclusions:
- The metaphyseal-diaphyseal junction is the recommended site for proximal and distal tibial osteotomies.
- The lower third of the tibia is not suitable for osteotomy due to anatomical or vascular considerations.
