Summary

This study details using large, vascularized iliac crest bone grafts for proximal femur reconstruction over nine years. This technique effectively addresses defects from tumor resection, nonunion, and avascular necrosis, preserving the femoral head.

Area of Science:

Orthopedic Surgery
Bone Reconstruction
Vascularized Bone Grafts

Background:

Reconstruction of large proximal femur defects presents significant challenges.
The femoral head is susceptible to destruction or collapse in conditions like tumor resection, femoral neck nonunion, and avascular necrosis.
Traditional methods may not adequately address complex proximal femur reconstructions, especially in young patients.

Purpose of the Study:

To evaluate the efficacy of large, vascularized iliac crest bone grafts in reconstructing proximal femur defects.
To present the author's nine-year experience with this reconstructive technique.
To demonstrate the utility of this method in managing challenging orthopedic conditions involving the proximal femur.

Main Methods:

Utilized large bone grafts with intact vascular pedicles harvested from the iliac crest.
Applied the technique for reconstruction of large defects in the proximal femoral region.
Managed cases including post-tumor resection defects, femoral neck nonunion, and avascular necrosis of the femoral head.

Main Results:

Satisfactory outcomes were achieved in a series of treated cases.
The vascularized bone graft technique proved effective in addressing complex proximal femur issues.
Preservation of the femoral head was successfully managed in at-risk patients.

Conclusions:

Large, vascularized iliac crest bone grafts are a valuable option for proximal femur reconstruction.
This technique offers a reliable solution for challenging defects and conditions threatening femoral head integrity.
The method demonstrates significant advantages in managing complex orthopedic problems in the proximal femur.
