Summary
Harvesting autogenous cancellous bone grafts from the proximal tibia using a manual trephine is a safe and effective method. This technique provides a predictable bone graft source for various osseous defects, with minimal donor site complications.
Area of Science:
- Orthopedic surgery
- Oral and maxillofacial surgery
- Regenerative medicine
Background:
- Autogenous cancellous bone grafts are crucial for osseous defect reconstruction.
- The proximal tibia is a common donor site for bone grafting.
- Minimally invasive harvesting techniques are desirable to reduce morbidity.
Purpose of the Study:
- To evaluate the efficacy and safety of using a manual trephine for harvesting bone grafts from the medial proximal tibia.
- To describe the surgical technique and anatomical landmarks for this approach.
Main Methods:
- A retrospective review of 33 patients who underwent bone graft harvesting from the medial proximal tibia using a manual trephine over a 3-year period.
- Detailed description of the surgical approach, including anatomical landmarks and the use of a manual trephine.
Main Results:
- The medial proximal tibia provided sufficient cancellous bone graft for all evaluated osseous defects, except for bilateral sinus lifts.
- No major complications were observed at the bone graft donor site.
- Minor complications included two cases of local infection and one unaesthetic scar; receptor site morbidity was linked to inadequate soft tissue coverage.
Conclusions:
- The medial approach to the proximal tibia using a manual trephine is a simple, safe, and predictable method for harvesting autogenous cancellous bone grafts.
- This technique offers a valuable option for obtaining bone grafts with low donor site morbidity.
