Ring sequestrum of proximal tibia in a polytrauma patient: A case report

Abstract

Ring sequestrum has become a rare presentation in modern day orthopaedics. It is a low grade chronic osteomyelitis following pintract infection producing an unusual sequestrum surrounded by radiolucent area another circle of sclerotic bone. Improper aseptic technique of skeletal pin traction, thermal necrosis, prolonged duration, poor pintract care and comorbid conditions can lead to this complications and presents with skin discharge, pin loosening and osteomyelitis. Thorough surgical debridement, sequestrectomy and saucerisation with appropriate antibiotics and dead space management will successfully treat it. We report a similar case in a polytrauma patient following pintract infection.
