Posttraumatic tibia valga in children. A long-term follow-up note

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Radiology

Background:

• Reevaluation of seven patients with progressive valgus deformity after proximal tibial metaphyseal fracture.
• Initial management was nonoperative, with previous reports recommending observation due to spontaneous improvement.

Purpose of the Study:

• To assess the long-term outcomes of nonoperative management for post-traumatic tibia valga.
• To evaluate the degree of spontaneous correction and functional results in affected limbs.

Main Methods:

• Long-term radiographic follow-up (average 15 years) of seven patients.
• Radiographic parameters included metaphyseal-diaphyseal angle, mechanical tibiofemoral angle, limb-length discrepancy, and mechanical axis deviation.
• Knee and ankle function were assessed using standardized rating systems.

Main Results:

• All patients showed spontaneous improvement in angulation, primarily at the proximal tibia.
• Average limb-length discrepancy was 9 mm, with the affected tibia being longer.
• Good to excellent knee and ankle function reported, with one patient undergoing osteotomy for persistent symptoms.

Conclusions:

• Spontaneous resolution of post-traumatic tibia valga is common, resulting in asymptomatic, well-aligned limbs.
• Nonoperative management and observation through skeletal maturity are recommended.
• Surgical intervention should be reserved for cases with symptoms attributable to malalignment.
