Management of open fractures. Septic and

non-septic complications in Traumatology.

Fractures of the tibia and fibula.

Fractures of the Tibia Anatomical characteristics:

• Anteromedial surface: thin soft tissue

coverage open fractures (13%)

• Osteo-fascial muscle compartments

compartment syndroma (≤ 20%)

• Dynamic framework

• Tension between tibia and fibula

• 1/6th of the load on the fibula

• Elastic load absorption

Conservative treatment

• Stable, non-dislocated fractures

• General condition of the patient

Traction for 3 weeks…

Cast: 9-12 weeks

Operative treatment

• Intramedullary nailing

• Plate synthesis

• External Fixator

Indications of intramedullary nailing

for the treatment of tibia fractures

• Best choice for fractures between the 2/7-6/7th

(shaft fractures) if it can be technically carried out

• Reamed nailing: monotrauma, patient is allowed to

bear weight earlier, good for cases of mal-union or

non-union

• Unreamed nailing: polytrauma, shorter operation

time, Grade lll- types B-, C open fractures, narrow

intramedullary canal.

• Interlocking: gives rotational stability, static

interlocking recommended, dynamisation can be

later performed. Mandatory in unreamed nailing.

Reamed Intramedullary Nailing

Unreamed intramedullary nailing – UTN

(Unreamed Tibia Nail)

IM nailing post operative care:

•if stability of the fracture is in question, then below knee cast

immobilization and touch down wt bearing are used until healing

•once partial fracture healing has taken place, consider a functional brace

or consider a below knee cast.

•active dorsiflexion and plantarflexion stresses the tibia and produces

displacements similar to wt bearing;

- static locking: most tibial fractures heal in the static locked mode;

- dynamization:

- removal of proximal or distal screws allows axial loading of tibia

- consider at 3 months in axially stable fractures with no callus

- axially unstable frx should remain in static mode and should receive bone

graft

Indications of plate synthesis

• Intraarticular fractures and fractures near

the joint (when ORIF is necessary)

• Non-union, malunion (with bone graft)

• When other methods of treatment are

contraindicated (e.g. compartment

syndrome)

Plate synthesis

Medial plate

Indications for External Fixation

• Severe soft tissue injury (Glll-BC) OPEN FRX

• In certain cases of polytraumatisation

• For intermittant limb shortening

• As a supplementation for minimal

synthesis epi-metaphyseal fractures

• Joint bridging

• Segment transfer, bone lengthening

Compartment syndrome

increasing tissue pressure prevents

capillary blood flow and produces

ischemia in muscle and nerve tissue. The

process is progressive and leads to

necrosis with permanent loss of function!

Surgical Emergency…..

Otherwise amputation

Intracompartmental pressure > 30 mmHg

Causes • High-energy limb injuries (most

often calf area)

• Crushing injuries

• Burns

• Prolonged compression (comatose,

unprotected patient)

• Abnormal capillary permeability

caused by reperfusion after

prolonged ischemia. Tight

bandages, splints, or

casts….Volkmann ischemic

contracture

Compartment syndrome

• Edema

• Pallor

• Pain „like childbirth”

• Pain to Passive

movement

• Local hyp/Paraesthesia

• Paresis

• Pulselessness

INFECTION: the most serious complication for

both the patient and the doctor!

• Contamination

bacteria on site

* bakterial culture

* temperature

drain-cultures

germs ↑

immune status ↓

• Infection

signs of bacterial inf.

* rubor (hyperemia)

* tumor (edema)

* calor (warm)

* dolor (painful)

* functio laesa (loss of

function

* pus

Causes of infection

• Open wounds / fractures

• Iatrogenic infections

- sterility problem

- ultrasterile boxes

• Circulation problems, diabetes

• Immune status

- transplants / steroids

- oncologic illness

• Operative errors

- haematomas, tissue damage

Classification of infections 1.

• Acute

- early posttraumatic period (1-7 days)

• Subacute

- (1 week- 1 month)

• Chronic

- (after 1 month)

Classification of infections 2.

• superficial

- skin necrosis

- epifascial supp.

good prognosis!

• deep

- subfascial

- intraarticular

- tendovaginal

- body cavity

- peri-implant

bad prognosis!

Superficial infection

• Diagnostics

- inspection

- palpation

- Ultrasound

- lab results

• Therapy

- conservative/kryoth.

- operative (revision,

debridement, perhaps

drainage)

Deep infection

• Diagnostics

- inspection

- palpation

- Ultrasound

- aspiration

- labs

• Therapy

- immediate revision,

debridement

- suction drainage

(vaccum sealing)

- perhaps Septopal chain

or antibiotic cement

Subfascial, extra/intraarticular

haematoma, tissue damage

Diagnostic methods

• Laboratory

- WBC

- qualitative blood

- We (Erythrocyte Sedimentation Rate)

- CRP

- procalcitonin

- TNF

• Instrumental

diagnostics

- sonography (punction)

- x-ray (gas, fluid)

- CT/contrast

- MRI/contrast

- scintigraphy

- thermography (?)

•obtain adequate cultures •Antibiotics should be considered only if the patient is systemically septic prior to wound exploration •Empirical antibiotic treatment is based upon the antibiotics sensitivities of likely infecting organisms

• history of previously positive cultures

• institutional frequency statistics

Antibiotic beads

Locally administered antibiotics may

have a supplementary role in the

management of musculoskeletal

infections.

poorly perfused areas, or “dead space”,

antibiotic-laden cement is frequently

used, both to fill the space and to

deliver high doses of local antibiotic

with low risk of systemic toxicity.

A common technique is the use of

antibiotic-laden PMMA beads.

Antibiotic-impregnated beads may

be purchased in some countries or

made by the surgeon more cheaply.
