Management of Necrotizing Fasciitis with Proximal Tibia Fracture.

[INTRODUCTION] Necrotizing fasciitis is a rare disease of soft tissue infection with a high mortality. It is characterized by rapidly spreading inflammation and necrosis of fascial planes. It usually follows an injury, though the cause may be a small abrasion or an insect bite or surgical incisions. It is commonly caused by bacteria such as Group A streptococcus. It may be accompanied by septic shock. It causes rapid death unless it is diagnosed quickly and managed aggressively. Prompt surgical debridement must be done to reduce mortality. Rapid diagnosis, antibiotic therapy, fluid resuscitation, and surgical debridement of the infection are all needed in the management of this fatal disease. However, when necrotizing fasciitis is associated with an underlying fracture the treatment becomes even challenging and limb-threatening.

[CASE REPORT] A 48-year-male patient of South Asian descent came to Emergency Room with history of road traffic accident and sustained injury to the right (RT) leg. He was admitted with pain, swelling and blisters of the RT leg and suspected to have necrotizing fasciitis with proximal tibia fracture of the RT leg. He was treated with thorough surgical debridement, broad-spectrum antibiotics, free flap, and Masquelet's technique with limb reconstruction system (LRS). At 18 months of follow-up the fracture healed, LRS was removed, pin tracts healed and patient was able to walk without any support.

[CONCLUSION] Necrotizing fasciitis is rare, rapidly progressive disease with a high mortality rate which requires prompt diagnosis, early surgical debridement, broad-spectrum antibiotics, careful fluid, and electrolyte management. These patients require a combined multidisciplinary approach for their management.
