Debridement and fixation of an open tibial fracture
The bone is the second problem: the operation is the radical cleaning of a contaminated wound, and only then stabilisation with metal outside or inside.
Indication: Open tibial fracture; the timing standard is early antibiotics, timely surgery, and joint orthoplastic decisions.

Stage
1 / 4
Wound extension and debridement
The wound is extended along fasciotomy-safe lines and every layer debrided: dead skin, fat, muscle and free bone fragments removed until everything left is healthy.
Watch for: Inadequate debridement seeding deep infection · Excising tissue that would have survived
The surgeon asks
Which tissue finding fails the four Cs and must go?
Why are we operating?
The operation for an open fracture treats a contaminated soft-tissue wound with a skeleton problem inside: radical debridement removes everything dead and foreign, lavage dilutes what remains, and stabilisation gives the soft tissues the still scaffold they need to heal. Its logic is orthoplastic from the first move, because the outcome tracks the envelope's reconstruction as much as the bone's.

What the surgeon is thinking
Wound extension and debridement
What does 'debride until it bleeds' actually mean?
Excision, not cleaning: skin edges, fat, fascia and muscle are removed until every surface is viable, judged by colour, contraction, consistency and bleeding. Bone fragments without soft-tissue attachment are dead and leave. The debridement is the infection-prevention operation; antibiotics only guard its margins.
Lavage
Why litres of simple saline rather than something cleverer?
Dilution is the mechanism: volume washes the bacterial load and particulate out of tissue planes, and trials taught that low pressure and plain saline do this as well as antiseptic additives, without their tissue cost. The lavage finishes what the knife started; it never substitutes for it.
Skeletal stabilisation
Why is stability itself an infection treatment?
Moving fragments shear the fragile revascularising tissue between them and keep dead spaces open: a stable skeleton lets the soft tissues seal and the blood supply rebuild. The choice of scaffold, external fixator now versus definitive nail, is a soft-tissue decision as much as a bone one.
Soft-tissue cover plan
Why does the plastic surgeon belong at the first operation?
Because the definitive plan is 'fix and flap' as one campaign: early soft-tissue cover (within days) lowers infection dramatically, and the debridement itself is done differently when the reconstructive plan is already drawn. The orthoplastic unit is not a luxury, it is the evidence.
Decision points
External fixation now or definitive nailing tonight?
Definitive internal fixation
For the clean-after-debridement wound with cover achievable early: one operation, one scaffold, in units set up to deliver it.
Spanning external fixator
For heavy contamination, physiologic instability or an unready envelope: travelling traction that holds length and alignment while tissues declare.
The bed decides the metal: implants live safely only in soft tissue that can cover and defend them. The staged answer is never a failure, but it is also not free, each stage is an anaesthetic and a delay, which is why orthoplastic centres try to earn the single-stage answer.
The limb is severely injured: mangled, insensate, ischaemic. Salvage or amputate?
Attempt salvage
For reconstructable limbs in patients whose physiology and life can fund years of surgery: the scores inform, they do not decide.
Early amputation
A well-made early amputation with good rehabilitation can outperform a salvage that fails at year three: a treatment, not a defeat.
This is a two-surgeon, senior, daylight decision made with the patient's life (work, pain, years of operations) on the table alongside the limb: the regret literature is full of both choices made badly and both made well. What convicts is deciding by momentum.
Leaving the OR
The handoff
- Procedure
- Debridement, lavage and spanning external fixation, open tibial fracture
- Wound
- Radical excision to bleeding margins; negative-pressure dressing; no primary closure
- Plan
- Joint orthoplastic relook and definitive fix-and-flap listed within 48-72h
- Antibiotics
- Started in ED within the hour; continued per protocol
- Watch for
- Compartments hourly, pin sites, analgesia-resistant pain as an alarm not a nuisance
A fictional educational patient, handed over the way real ones are.
The postoperative course
- POD 0-1Elevation, compartment vigilance and the neurovascular chart continued: the danger did not end at closure of the case, because there was no closure.
- POD 2-3The planned return: relook debridement, and the definitive skeleton-plus-cover operation when the wound has earned it.
- Week 1-2Flap or graft monitoring where used; mobilisation within the fixation's rules; infection surveillance with a low imaging threshold.
- MonthsUnion watched on serial films; the non-union and infection questions asked openly at each clinic rather than hoped away; rehabilitation is the second half of the operation.
