Summary
This study shows bone transport using the RALCA external fixator is effective for treating chronic osteomyelitis involving bone resection, achieving good clinical and radiologic outcomes.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Management
Background:
- Chronic osteomyelitis of the distal tibia presents a significant treatment challenge, often requiring extensive bone resection.
- External fixation techniques offer a viable solution for managing complex bone defects and infections.
Observation:
- A case study involving a young male patient with chronic osteomyelitis of the distal tibia, secondary to a Gustilo IIIB fracture.
- Surgical intervention included resection of the infected bone segment.
Findings:
- The application of the RALCA (Redução Aberta, Luxação Controlada, Alongamento) external fixator facilitated effective bone transport.
- Achieved 9 cm of bone regeneration, leading to favorable clinical and radiological results.
Implications:
- Bone transport with external fixation is a highly effective method for treating osteomyelitis requiring bone resection.
- The RALCA external fixator demonstrates technical utility and successful application in complex orthopedic infections.
