Definition of open fracture
• A broken bone that is in communication through the skin with the environment
![Page 4: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/4.jpg)
Classification
• Gustilo and Anderson classification of open #
– Based on1. Size of wound2. Amount of soft tissue injury3. Presence/absence of NV injury4. Degree of contamination
![Page 5: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/5.jpg)
Classification - I– Clean wound <1 cm in diameter– Simple # pattern with minimal
comminution– Minimal soft tissue injury
![Page 6: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/6.jpg)
Classification - II• Laceration >1 cm
diameter• Moderate soft tissue
damage (no flaps, degloving, or contusion)
• # pattern may be more complex
• Moderate contamination
![Page 7: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/7.jpg)
Classification - III– An open segmental # or a single # with
extensive soft-tissue injury. Also included are injuries older than 8 hours• >10cm long• Highly contaminated• Usually comminuted
– IIIA, IIIB, IIIC• Depends on soft tissue injury
![Page 8: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/8.jpg)
Classification - IIIA• Severe soft tissue injury• Adequate soft-tissue
coverage of the # is likely (despite high-energy trauma or extensive laceration or skin flaps)
![Page 9: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/9.jpg)
Classification - IIIB• Inadequate soft-tissue
coverage with periosteal stripping
• Soft-tissue reconstructive surgery is necessary

Classification - IIIC
• Associated vascular injury that requires repair• Reconstructive surgery for skin coverage
![Page 11: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/11.jpg)
Management aims– Prevent infection– Ensure # healing– Restore function
![Page 12: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/12.jpg)
Management• Analgesia• Fluid/blood replacement• Splinting• Antibiotics• Tetanus prophylaxis• Take photo• Cover wound• Surgical debridement• Stabilise #

Use of antibiotics
• Cochrane review 2009 – “Antibiotics for preventing infection in open limb fractures”– 1106 participants– 8 studies (5 RCT, 3 quasi-randomised)– Use of antibiotics had a protective effect
against early infection compared with no antibiotics or placebo (risk ratio 0.43, 95% CI 0.29 to 0.65)
![Page 14: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/14.jpg)
Which antibiotics?
• BOA/BAPRAS guidelines for lower limb open # (2009):– IV co-amoxiclav 1.2g TDS until 1st
debridement (if penicillin allergic IV clindamycin 600mg QDS)
– At induction of anaesthesia• Gentamicin 1.5mg/kg• Plus teicoplanin 800mg or vancomycin 1g
– Post op continue IV augmentin 1.2g TDS until wound closure or max. of 72 hours

Timing of debridement
• Kindsfater et al 1995– 47 tibia fractures (25 grade II, 22 grade III)– Jan 1988 to Jan 1992– Initial debridement:
• < 5 hours - 7% infection rate• > 5 hours - 38% infection rate• Overt manifestations of infection - 4.8 months
![Page 16: Open Fracture](https://reader030.vdocuments.site/reader030/viewer/2022033108/5879079b1a28ab6f658b5261/html5/thumbnails/16.jpg)
Timing of debridement
• BOA/BAPRAS guidelines lower limb open # (2009)– Within 24 hours if solitary open # by senior
plastic & ortho surgeons on scheduled list– However immediately if:
• gross contamination• compartment syndrome• devascularised limb• multi-injured pt

Complications
• Wound infection• Osteomyelitis• Non-union• Tetanus infection• Neurovascular injury• Compartment syndrome

Risk of infection (Sorger, 1999)
Grade of open fracture (Gustilo-Anderson)
Risk of infection (%)
I 0 – 12
II 2 -12
III 9 - 55

Summary
• Gustilo-Anderson classification• Grade I, II, III (A/B/C) dependent on
wound size, amount of soft tissue injury, degree of contamination & NV injury
• Take photo & cover wound• Antibiotics & early debridement
