Worsening pain and tense compartments triggers compartment syndrome escalation
Open fracture medications and timing
Antibiotics and tetanus
Antibiotic timing target
As early as possible after recognition
Do not delay for imaging if open fracture evident
Antibiotic selection by Gustilo category
Type I or II coverage
Cefazolin IV 2 g every 8 hours
Weight 120 kg or more cefazolin IV 3 g every 8 hours
Severe beta lactam allergy clindamycin IV 900 mg every 8 hours
Type III coverage
Ceftriaxone IV 2 g daily
Add gentamicin IV 5 mg per kg daily per local protocol if high contamination
Severe beta lactam allergy clindamycin IV 900 mg every 8 hours plus ciprofloxacin IV 400 mg every 12 hours
Farm or fecal contamination concern
Add metronidazole IV 500 mg every 8 hours
Alternative clindamycin already provides anaerobe coverage
Freshwater exposure
Add fluoroquinolone per local protocol
Saltwater exposure
Add doxycycline 100 mg PO or IV every 12 hours plus ceftazidime per local protocol
Tetanus prophylaxis
Clean minor wound with unknown or under 3 doses
Tetanus toxoid vaccine
Dirty wound with unknown or under 3 doses
Tetanus toxoid vaccine
Tetanus immune globulin 250 units IM
Irrigation and dressing principles
Gross contamination removal at bedside if feasible
High pressure irrigation deferred to OR debridement pathway when indicated
Moist sterile dressing and splint
Urgent operative timing principles
Early debridement for gross contamination or vascular compromise
Early fixation planning based on soft tissue status
DVT prophylaxis when relevant
VTE prevention planning
Risk factors
Lower limb immobilization
Planned operative fixation
Prior VTE
Active cancer
Estrogen therapy
Prolonged immobility
Pharmacologic prophylaxis discussion
Enoxaparin dosing per local protocol if admitted and no contraindications
Hold if active bleeding or impending surgery per ortho plan
Mechanical prophylaxis
Intermittent pneumatic compression if admitted and pharmacologic held
Documentation elements
Indication and plan
Contraindications if not used
Special Populations
Pregnancy
Pregnancy considerations
Imaging principles
Radiographs acceptable with shielding when clinically needed
CT reserved for maternal benefit when indicated
Analgesia and sedation
Acetaminophen preferred baseline
NSAID avoidance in later pregnancy per obstetric guidance
Opioid use lowest effective dose
VTE risk
Pregnancy hypercoagulable state
Lower threshold for prophylaxis planning when immobilized
Obstetric coordination
Fetal monitoring per gestational age and trauma severity
Geriatric
Older adult considerations
Fragility context
Lower energy mechanism possible
Osteoporosis evaluation follow up planning
Medication safety
Opioid delirium risk
NSAID renal and GI risk
Disposition thresholds
Higher admission threshold with mobility limitations
PT OT needs and fall risk
Pediatrics
Pediatric considerations
Growth and remodeling
Remodeling potential depends on age and deformity plane
Rotational deformity remodels poorly
Non accidental trauma context
Inconsistent history with injury pattern triggers safeguarding pathway
Analgesia dosing
Weight based dosing for all meds
Ketamine IV 1 mg per kg for procedural sedation typical starting dose
Compartment syndrome vigilance
Increasing analgesic need as early clue
Anxiety and agitation as possible early sign
Background
Epidemiology
Frequency and burden
Tibial shaft fracture is among the most common long bone fractures
High proportion related to high energy trauma
Open fracture proportion higher than many other long bones
Open tibial shaft fracture approximate proportion
Reported ranges commonly around 10 to 25 percent depending on setting
Compartment syndrome occurrence in tibial shaft fractures
Reported ranges commonly around 1 to 9 percent depending on energy and pattern
Pathophysiology
Biomechanics and pattern mapping
Bending forces
Transverse pattern tendency
Comminution with high energy
Torsional forces
Spiral or oblique pattern tendency
Rotational malalignment risk
Axial load
Comminution and shortening risk
Associated plafond or plateau extension concern
Soft tissue vulnerability
Anteromedial tibia thin soft tissue envelope
Higher open fracture risk with direct impact
Neurovascular proximity
Anterior tibial artery and deep peroneal nerve at risk in proximal anterior compartment injuries
Posterior tibial structures at risk with deep posterior compartment swelling
Therapeutic Considerations
Nonoperative versus operative rationale
Operative fixation common for displaced tibial shaft fractures
Intramedullary nailing typical for many diaphyseal patterns
External fixation or staged fixation for severe soft tissue injury
Nonoperative casting or functional bracing for select stable fractures
Close alignment monitoring required
Malunion and delayed union risks discussed
Infection prevention in open fractures
Earlier antibiotics associated with lower infection risk in observational evidence
Early debridement and soft tissue management central to outcomes
Compartment syndrome time dependence
Delayed fasciotomy associated with worse outcomes and infection risk
Patient Discharge Instructions
Copy discharge instructions
Discharge instructions
Immobilization care
Keep splint clean and dry
Do not insert objects into splint
If splint feels too tight, loosen wrap and return for reassessment
Elevation and swelling control
Elevate above heart as much as possible for first 48 to 72 hours
Ice around splint as tolerated
Weight bearing
Non weight bearing unless explicitly told otherwise
Crutches or walker use every time standing
Pain plan
Acetaminophen per label maximum daily dose
NSAID only if safe for kidneys stomach bleeding risk
Opioid only as prescribed and avoid driving
Return to ED immediately
Increasing pain not controlled with meds
Numbness or tingling in foot or toes
Toes cold pale or blue
Inability to move toes
Splint suddenly too tight or severe pressure spots
Fever or wound drainage or foul smell if wound present
Follow up
Orthopedics appointment within timeframe provided
Earlier return if swelling increases or splint becomes loose or damaged
