Insights
Early surgical correction of infantile tibia vara (Blount disease) using proximal tibial osteotomy leads to better outcomes. Late surgery or recurrence can result in pain and degenerative changes.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Skeletal Dysplasias
Context:
- Infantile tibia vara (Blount disease) is a progressive condition affecting lower limb alignment.
- Proximal tibial osteotomy is a surgical intervention to correct the deformity.
- Long-term outcomes of this procedure require further investigation.
Purpose:
- To evaluate the long-term clinical and radiographic outcomes of proximal tibial osteotomy in patients with infantile tibia vara.
- To identify factors influencing functional recovery and the development of degenerative changes post-surgery.
Summary:
- This study analyzed 23 patients with infantile tibia vara treated with proximal tibial osteotomy between 1968 and 1992.
- Follow-up averaged 14 years, with main complaints including pain and impaired knee function.
- Early surgical intervention (before age 5) correlated with pain-free outcomes and good knee function.
- Late surgery or recurrent deformity was associated with early degenerative changes.
Impact:
- Optimal surgical timing is crucial for preventing long-term complications in infantile tibia vara.
- Knee joint line orientation is a significant factor in post-operative knee function.
- Findings inform surgical decision-making and patient selection for proximal tibial osteotomy.
Abstract:
We are presenting 23 patients with infantile tibia vara (Blount disease) treated with proximal tibial osteotomy between 1968 and 1992. Average age at the osteotomy was 6 years and 4 months. Average age at the final follow-up was 20 years and 5 months. Average length of follow-up was 14 years. Patients were evaluated clinically and radiographically. The main complaint at the final check-up was pain. Correction of the lower leg alignment did not guarantee good knee function. Horizontal orientation of the knee joint line seems to influence greatly the knee function. Patients operated on before the age of 5 were pain free with good knee form and function. In majority of those either operated on late or with recurrence of deformity early degenerative changes ensued.
