Treatment of chronic osteomyelitis in children resistant to previous therapy

Area of Science:

• Orthopedics
• Pediatric Infectious Diseases
• Surgical Innovation

Background:

• Chronic pediatric tibial osteomyelitis presents complex treatment challenges.
• Many cases are resistant to initial therapeutic modalities.
• Long-term management often involves multiple surgical procedures.

Purpose of the Study:

• To determine the incidence, etiology, treatment, and outcomes of chronic pediatric tibial osteomyelitis.
• To describe surgical strategies for pediatric osteomyelitis refractory to prior treatments.
• To evaluate the efficacy of Ilizarov distraction osteogenesis in complex tibial defects.

Main Methods:

• Retrospective review of pediatric patients with tibial osteomyelitis (1978-1998).
• Analysis of patient demographics, disease duration, and number of procedures.
• Assessment of causative pathogens, treatment protocols, and patient outcomes.
• Evaluation of tibiofibular synostosis and Ilizarov bone transport for tibial defects.

Main Results:

• Thirty pediatric patients identified with a mean age of 8.5 years at diagnosis.
• Staphylococcus aureus was the most frequent pathogen (78% of positive cultures).
• Eighty percent of patients achieved a good outcome, with no poor results reported.
• Successful treatment of large tibial defects using Ilizarov bone transport was observed.

Conclusions:

• Chronic pediatric tibial osteomyelitis requires extensive surgical management.
• Staphylococcus aureus is a primary causative agent.
• Ilizarov distraction osteogenesis offers a viable solution for complex bony tibial defects in children.
• Positive outcomes are achievable even in severe, refractory cases.
