The medial proximal tibial bone harvest offers a safer surgical window with fewer neurovascular risks compared to other methods. This approach may lead to improved patient outcomes and a more straightforward procedure for surgeons.
Area of Science:
- Orthopedic surgery
- Anatomical studies
- Bone grafting techniques
Background:
- Iliac crest bone harvesting is standard but requires specialized personnel and general anesthesia.
- Proximal tibial bone harvest (PTBH) is increasingly popular for autogenous bone grafting.
- Literature suggests PTBH offers shorter hospital stays, reduced morbidity, and a quicker learning curve.
Purpose of the Study:
- To analyze the clinical anatomy of the proximal tibia for bone harvesting.
- To identify anatomical landmarks supporting a safe and effective PTBH procedure.
Main Methods:
- Dissection of 58 lower limbs from embalmed cadavers.
- Evaluation of anatomical structures relevant to PTBH.
Main Results:
- The medial approach to PTBH presents fewer clinically significant neurovascular structures at risk.
- The medial approach provides a larger surgical surface area, enhancing procedural confidence.
- A safe surgical window is achievable via the medial PTBH approach.
Conclusions:
- The medial PTBH approach demonstrates a favorable anatomical basis with reduced risk to critical structures compared to the lateral approach.
- The lateral approach may be a suitable option for specific patient subgroups.
- Anatomical understanding supports the safety and efficacy of the medial PTBH.
