- Segmental fracture
- Open fracture
- Compartment syndrome
- Vascular injury
- “Floating” knee
- Knee ligamentous injury
- Polytrauma
- Pathologic fracture
Goals of surgical treatment of tibial shaft fractures (5)
- Timely wound coverage/closure
- Prevention of infection
- Restoration of limb length, alignment, rotation and stability
- Fracture healing
- Return of function
Steps of nonoperative management of tibial shaft fractures (4)
- Long-leg cast with knee in 15° of flexion
- Non-weight bearing until soft callus forms (XR, no pain on palpation)
- Switch to PTB cast or fracture brace with progressive WB and PT
- Discontinue immobilization when clinical and radiographic healing
Principles of surgical treatment of tibial shaft fractures (5)
- Aggressive management of open injuries
- Early soft tissue coverage
- Restore limb length, alignment and rotation
- Stable internal fixation
- Early knee and ankle ROM
Principles of plate fixation of tibial shaft fractures (5)
- Avoid disruption of fracture hematoma/remaining soft tissues
- Proper plate contouring
- Use of large fragment hardware
- 8 cortices on each side of the fracture
- Lag screws for interfragmentary compression only if placed with minimal soft tissue disruption
Advantages of nail fixation over plate fixation/ex-fix of tibial shaft fractures (5)
- Decreased time to union (both – closed #)
- Increased union rate (both – closed #)
- Decreased malalignment (ex-fix)
- Decreased secondary surgeries (ex-fix)
- Shorter time to weight bearing (ex-fix)
- Improved functional outcome (ex-fix)
- Shorter hospital stay (ex-fix)
Methods to avoid valgus/procurvatum deformity in IM nailing of proximal 1/3 tibial shaft fractures (5)
- Posterior and lateral blocking screws
- Lateral start point
- Nailing in extension
- Suprapatellar nailing
- Unicortical plating
Indications for amputation with tibial shaft fractures (9)
- Limb is a threat to patient’s life
- Non-viable limb
- Irreparable vascular injury
- Warm ischemia time > 6 hours
- Severe crush with minimal viable soft tissue
- Irreparable ipsilateral foot trauma
- Reconstruction demands incompatible with patient’s personal/sociologic/economic needs
- Salvage may precipitate MOSF/ARDS
- Segmental tibial loss > 8 cm
Complications of tibial shaft fractures
- Anterior knee pain (30 - 50% resolve with hardware removal)
- Compartment syndrome (5%)
- Infection (deep 1% closed, 25-50% IIIB)
- Vascular injury
- Malunion
- Nonunion
- Wound healing complications
- Delayed union
Risk factors for delayed union/nonunion of tibial shaft fractures (3)
- Mid-third fractures
- Greater initial displacement
- Intact/rapidly healed fibula
- Open fracture
- Opening the fracture site at surgery
- Medical comorbidities
- Smoking
Risk factors for infection in tibial shaft fractures
- Open fracture
- Delayed soft tissue coverage (> 7-10 days)
Risk factors for malunion of tibial shaft fractures (6)
- Shorting
- Same level fibula fracture
- Comminution
- Intact fibula
- Proximal fracture
- Distal fracture
Options for soft tissue coverage of open tibial fractures (7)
- Local rotational flaps
- o Gastrocnemius (proximal)
- o Soleus (mid-1/3)
- o Peroneals (mid-1/3)
- Free tissue transfer
- o Fasciocutaneous flaps (ALT, volar forearm, lateral arm)
- o Myofasciocutaneous flaps (rectus abdominus, latissimus dorsi)
- o Free muscle flaps followed by split-thickness skin grafting
- o Osteocutaneous flaps (iliac crest, vascularized fibula)
