Microvascular fibular grafts in skeleton reconstruction

Area of Science:

• Orthopedic Surgery
• Microsurgery
• Regenerative Medicine

Background:

• Extensive bone defects often necessitate large bone grafts, which conventional methods struggle to repair.
• Microsurgery has revolutionized the treatment of severe bone defects, previously leading to amputation.
• Idiopathic femoral head necrosis is a primary indication for advanced reconstructive techniques.

Purpose of the Study:

• To present a novel classification for idiopathic femoral head necrosis.
• To describe a microsurgical technique for treating extensive bone defects, focusing on femoral head necrosis.
• To highlight the benefits of free microvascular (fibular) transfer in bone reconstruction.

Main Methods:

• Free microvascular (fibular) transfer involves transferring fibular bone with its vascular pedicle.
• The technique provides mechanical support and enhances blood supply to the affected area.
• A specific surgical approach has been refined and utilized over 14 years.

Main Results:

• Free microvascular fibular transfer effectively addresses large bone defects where conventional grafts fail.
• The procedure offers a successful alternative to amputation for conditions like idiopathic femoral head necrosis.
• The fibula is preferred due to its structural integrity and vascularity.

Conclusions:

• Free microvascular fibular transfer is a crucial advancement in treating extensive bone defects.
• The described technique offers a reliable solution for idiopathic femoral head necrosis, improving patient outcomes.
• Microsurgical bone transfer provides a viable alternative to amputation, restoring function and form.
