Humeral lengthening using Ilizarov external fixation effectively corrects arm shortening and deformities. This method allows for significant length increase up to 100% with good functional outcomes and manageable complications.
Area of Science:
- Orthopedic surgery
- Limb reconstruction
- External fixation
Background:
- Ilizarov principles and hybrid fixation enhance humeral lengthening outcomes.
- Retrospective review of 56 segments in 46 patients treated for humeral lengthening and deformity correction.
- Etiologies included achondroplasia, epiphyseal injury, infection, and Erb's palsy.
Approach:
- Retrospective cohort study (Level of Evidence IV).
- Utilized Ilizarov external fixation for humeral lengthening and deformity correction.
- Clinical and radiographic assessments, including DASH scores, were performed.
Key Points:
- Average lengthening of 9 cm achieved (5-15.5 cm range).
- Significant improvement in DASH scores from 15-40 preoperatively to 7-16 postoperatively (P=0.04).
- All patients returned to their preoperative activities, including sports.
Conclusions:
- Humeral lengthening is a valid method for correcting arm shortening and deformities.
- Extensive lengthening up to 100% is achievable without increased complication risk.
- Ilizarov fixation provides effective limb lengthening and functional restoration.
