Hardware Preservation in Management of Infected Non United or Delayed United Fractures of Long or Short Bones by Debridement and Local Calcium Sulfate Loaded by Antibiotics

Infected Non Union and Delayed Union in Fractures of Both Long and Short Bones

* Diagnosis of infection based on elevated serum markers of infection (ESR, CRP), discharging sinus, preoperative radiographs suggestive of bone infection and radiological findings . \[6\] * infected nonunion mean the bone has previous fracture , the bone not healed may be one of the reasons it didn't heal because there is sub-acute infection , there is low grade colonization into the bone or around the wound preventing the bone from healing , it different from infected fracture which occur fairly acutely. \[6, 7\] * Infected nonunion treated with systemic antibiotics alone, without using local antibiotic delivery systems associated with higher recurrence and reoperation rates. \[7\] * This led to the development and use of medical-grade calcium sulfate (CS), CS facilitates osseous healing in an osteoconductive fashion by filling the bone void and preventing fibrous tissue
