Summary
The Ilizarov method effectively treats lower limb deformity and shortening. This study found no significant differences between monofocal and bifocal treatments, suggesting monofocal may be less invasive for shorter lengthening needs.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Lower limb deformities and shortening present complex orthopedic challenges.
- The Ilizarov method offers a versatile approach to limb reconstruction.
Purpose of the Study:
- To evaluate the efficacy of the Ilizarov method for treating combined lower limb deformity and shortening.
- To compare monofocal versus bifocal treatment strategies and analyze outcomes for femoral versus tibial procedures.
Main Methods:
- Retrospective analysis of 17 patients (18 lower limb segments) treated with the Ilizarov method.
- Limb lengthening performed via monofocal or bifocal osteotomy, with acute or gradual deformity correction.
- Evaluation of external fixation time, deformity correction, length gained, and complication rates.
Main Results:
- Average deformity correction was 22.3 degrees; average lengthening was 44.4 mm.
- Mean external fixation index was 49.3 days/cm; mean fixation duration was 198 days.
- Four patients experienced major complications; no significant differences were found between monofocal/bifocal or femoral/tibial treatments.
Conclusions:
- The Ilizarov method is highly effective for treating lower limb deformity with shortening.
- Monofocal treatment may be preferable for shorter lengthening requirements to minimize surgical invasiveness.
- Further research is needed to verify longer treatment indices for tibial operations.
