Management Open FractureManagement Open Fracture immediately after accident (golden period)immediately after accident (golden period)

Debridement :Debridement :- Wound cleaning by irrigation- Wound cleaning by irrigation- Surgery : excite the dirty soft tissue - Surgery : excite the dirty soft tissue

and remove the necrotic tissueand remove the necrotic tissue

The GoalThe Goal of treatment of an open fracture are of treatment of an open fracture are prevention of infection, healing of the fracture prevention of infection, healing of the fracture and restoration of the function in the extremity and restoration of the function in the extremity

Grade I – II after debridementGrade I – II after debridement the bone can be fixed by internal fixationthe bone can be fixed by internal fixation

Grade III after debridementGrade III after debridement the bone can be fixed by external fixationthe bone can be fixed by external fixation ( - Monolateral external fixation( - Monolateral external fixation - Circular external fixation- Circular external fixation - Quadrilateral external fixation) - Quadrilateral external fixation)

➣➣ Soft tissue closed may carried out immediately Soft tissue closed may carried out immediately with skin graft or flap (primary repair)with skin graft or flap (primary repair) if impossible to close the soft tissue if impossible to close the soft tissue should be performed by delayed repairshould be performed by delayed repair
