Three-Column Fixation for Complex Tibial Plateau Fractures.

·J Orthop Trauma·2010·531 citations·Trauma
DOI·PubMed
SummaryAbstract on PubMed →

This prospective cohort from a Level 1 trauma center introduces a CT-based 'three-column' concept for classifying and fixing complex tibial plateau fractures. It asks whether column-specific fixation using a novel 'floating position' and combined posterior plus anterolateral approach can safely address the posterior column — which standard bilateral dual plating cannot reach. The study reports clinical and radiographic outcomes in 29 patients at minimum 2-year follow-up.

Whether three-column fixation improves outcomes in complex tibial plateau fractures
Outcome(s)
Functional outcome (HSS score, LEM) at 24 months
Subjects
29 patients, Schatzker V/VI tibial plateau fractures
  • Three-column ORIF via posterior inverted L + anterolateral approach
Inclusion
  • Schatzker Type V or VI fracture
  • Three-column fracture on CT
  • Closed fracture

Statistics
One-way ANOVAStudent t-testPearson correlation

Key Findings

  • Only 12% of tibial plateau fractures (33/266) qualify as true three-column fractures — most Schatzker V/VI fractures do NOT have an independent posterior column fragment and can be managed without this technique.
  • The three-column classification uses CT axial landmarks to divide the proximal tibia into three zones; a true three-column fracture requires at least one independent articular fragment in EACH:
    –Lateral column: anterior tibial tuberosity → fibular head (line OA to OC)
    –Medial column: anterior tuberosity → posteromedial ridge (line OA to OD)
    –Posterior column: posterior to both OC and OD, subdivided by point B into posteromedial and posterolateral zones
  • Plain radiographs underevaluated fracture complexity in 43% of cases and changed the operative plan in 60% after CT — establishing the evidence base for mandatory CT before any complex tibial plateau fixation.
  • Radiographic union averaged 13.1 weeks and full weightbearing 16.7 weeks, with zero cases of secondary articular depression at two years — validating the durability of direct posterior buttress fixation over anterolaterally aimed locking screws.
  • Tibial plateau alignment held at two years with no statistically significant change in tibial plateau angle or posterior slope (P = 0.840, 0.060, 0.061), confirming that column-specific buttress plating maintains reduction where cantilever constructs eventually fail.
Board PearlOnly 12% of tibial plateau fractures are true three-column fractures — CT is required to identify posterior column involvement that standard dual plating cannot address.

Clinical Relevance

Standard Schatzker and AO systems are built on AP radiographs and point surgeons toward medial and lateral fixation. The posterior column simply does not exist in those frameworks — which is why posterolateral articular fragments were routinely missed or inadequately fixed before CT-based planning became standard.

When you see a Schatzker V or VI fracture, get a CT before finalizing your plan. If the CT shows an independent articular fragment in the posterior column with a break of the posterior wall, you are dealing with a three-column fracture. Standard dual plating will not adequately reduce or hold that posterior fragment.

For true three-column fractures, plan a combined inverted L-shaped posterior approach plus anterolateral approach using the floating position. The posterior approach lets you directly visualize and buttress both posteromedial and posterolateral zones through a single incision and a fracture window. No second posterolateral incision needed.

Remember: posterolateral depression is impossible to reduce from the supine position. The floating position exists precisely because you need prone orientation for the posterior column, then can rotate to address the lateral column without re-draping.
