Surgical wound dehiscence with exposed ulnar plates can heal without infection. This case shows bone consolidation despite a forearm plate being exposed for six years.
Area of Science:
- Orthopedic Surgery
- Trauma Management
Background:
- Surgical wound dehiscence with exposed internal fixation is a significant orthopedic complication.
- It is a major risk factor for deep bone infection.
Observation:
- An adult patient presented with a 20 cm ulnar plate fully exposed six years post-surgery for a Monteggia fracture-dislocation.
- The patient had a history of drug dependence and no follow-up care.
- Remarkably, there were no signs of infection, and the fracture had healed with misalignment.
Findings:
- The exposed ulnar plate, despite prolonged exposure, did not lead to infection.
- Spontaneous epithelialization occurred over the bone bed after plate removal.
- Complete skin coverage was achieved within two months.
Implications:
- This case demonstrates that bone consolidation is possible even with long-term exposure of internal fixation devices in adults.
- It challenges the assumption that exposed hardware invariably leads to infection in open fractures.
- Highlights the potential for unexpected healing outcomes in complex orthopedic cases.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
