[Instillation vacuum sealing--report of initial experiences]

Area of Science:

• Infectious Diseases
• Surgical Techniques
• Drug Delivery Systems

Context:

• Osteomyelitis, a bone infection, can be acute or chronic, posing treatment challenges.
• Traditional treatments may have limitations in effectively eradicating infection and promoting healing.
• Novel therapeutic strategies are needed to improve patient outcomes for bone infections.

Purpose:

• To evaluate the efficacy of a novel instillation vacuum-sealing technique for treating acute and chronic osteomyelitis.
• To assess the role of polyvinyl alcohol (PVA) sponges as a drug-release system for antibiotics and antiseptics in this technique.
• To determine the recurrence rate of infection following treatment with this novel method.

Summary:

• A cohort of patients with acute (n=13) and chronic (n=14) osteomyelitis were treated using instillation vacuum-sealing.
• This technique utilizes polyvinyl alcohol (PVA) sponges as a localized drug delivery system for antibiotic and antiseptic solutions.
• The treatment demonstrated a low recurrence rate, with only one case of chronic osteomyelitis recurrence observed during a mean follow-up of 4.2 months.

Impact:

• This study introduces a promising novel technique for managing osteomyelitis, potentially improving infection control.
• The use of PVA sponges as a drug-release system offers a targeted approach to antibiotic and antiseptic delivery.
• The findings suggest that instillation vacuum-sealing may be an effective treatment option, reducing the risk of infection recurrence.
