Summary

This study introduces a novel Ilizarov hip reconstruction technique using only internal implants, offering a patient-friendly alternative to traditional external fixation methods for hip dislocation. The new approach resulted in successful leg equalization and improved gait without complications.

Area of Science:

Orthopedic surgery
Reconstructive surgery

Background:

The Ilizarov hip reconstruction is a recognized salvage procedure for chronically dislocated hips.
Traditional Ilizarov hip reconstruction relies on external fixation, which is associated with a high complication rate.
Fully implantable devices are advantageous but have not been used for Ilizarov hip reconstruction until now.

Purpose of the Study:

To present a novel technique for Ilizarov hip reconstruction utilizing exclusively internal implants.
To evaluate the feasibility and patient outcomes of this new internal fixation method.

Main Methods:

A 14-year-old patient with spina bifida and significant leg length discrepancy underwent Ilizarov hip reconstruction without external fixation.
A locking compression plate stabilized the proximal femoral osteotomy.

Keywords:

A motorized intramedullary nail facilitated the distal osteotomy for lengthening and varization.

Main Results:

The procedure achieved a healing index of 33 days/cm.
Full weight-bearing was attained at 6 months post-surgery.
One-year follow-up demonstrated improved gait, leg length equalization, reduced pain, and high patient satisfaction with cosmetic outcomes.
No complications were reported.

Conclusions:

Exclusive use of internal implants for Ilizarov hip reconstruction is a viable and patient-preferred alternative.
This technique offers a less complicated and more comfortable solution compared to external fixation.
Potential limitations may arise due to specific geometric patient conditions.
