Abstract

Insights

Physicians should be aware of myiasis, a rare complication of external fixation for fracture treatment. Prompt wound care and maggot removal are crucial for managing this condition.

Area of Science:

  • Medical Entomology
  • Orthopedic Surgery
  • Infectious Diseases

Background:

  • Myiasis, an infestation by fly larvae, can occur as a complication in fracture treatment.
  • External fixation devices, while effective for fracture stabilization, may present risks for wound complications.

Purpose of the Study:

  • To report a rare case of pin-tract myiasis in a patient undergoing external fixation for a complex fracture.
  • To highlight the importance of vigilant wound care and preventative measures against myiasis in orthopedic surgery.

Main Methods:

  • A case study of a 45-year-old male with a Gustilo-Anderson type IIIB fracture of the tibia and fibula treated with external fixation.
  • Clinical presentation involved maggots and foul discharge from the pin tract, leading to a diagnosis of abscess with pin-tract myiasis.

Main Results:

  • The patient presented with a severe pin-tract infection characterized by multiple maggots and purulent discharge.
  • Successful management involved wound debridement and complete removal of the maggots, resolving the myiasis.

Conclusions:

  • This case underscores the potential for myiasis to re-emerge as a surgical complication, particularly with the use of external fixators.
  • Emphasizes the critical role of meticulous wound care, simple precautions, and risk factor avoidance in preventing fly larvae infestations in surgical sites.
