Diagnosis Path: Detailed review of the patient’s medical history and procedural notes Physical examination of the surgical site for signs of infection, inflammation, or retained foreign materials Imaging tests such as X-rays, ultrasounds, or CT scans to detect broken or retained device fragments Laboratory tests to identify infections or allergic reactions Inspection of used devices and documentation of equipment malfunction or damage Consultation with the surgical team to understand the circumstances of the adverse event

Treatment Protocols: Wound care and management to promote healing and prevent infection Administration of antibiotics or anti-inflammatory medications as needed Surgical removal of broken, damaged, or retained device fragments Addressing allergic or adverse reactions through medication or supportive care Repair or reconstruction of damaged tissues or structures Enhanced monitoring and follow-up to ensure complete recovery Implementation of corrective measures to prevent recurrence, such as device replacement or procedural adjustments
