Tibial Plateau Fractures: Factors influencing outcomes

Transcription

1 Tibial Plateau Fractures: Factors influencing outcomes May 20th 2013 Joel Melton BM, MSc, FRCS (Tr + Orth) Consultant Orthopaedic Surgeon, Cambridge University Hospitals

2 Overview Plateau Fractures Diagnosis Classifications Treatment goals Management decisions Surgical techniques Controversies Factors influencing outcome

3 Diagnosis History, Clinical examination, Special tests Minor, major or catastrophic injury May be subtle or obvious Remember other injuries Degree of soft tissue injury (inc. open)

4 Diagnosis special tests Plain radiography CT scan MRI? Diagnosis Fracture pattern Help with classification Assess joint displacement Guide need for operative intervention Guide the operative fixation plan and surgical approaches

5 Classification Jo Schatzker Types 1-6 Worsening severity by type May guide fixation techniques and likely outcomes

6 Types 1-6 Classification - Schatzker

7 Treatment goals G. Appley Reduce fracture, hold position and rehabilitate The AO group AO principles dictate: An intraarticular fracture must be anatomically reduced, fixed with rigid internal fixation, conferring absolute stability to the fracture, expecting primary bone healing and allowing early joint mobilisation

8 Treatment goals Applying this to plateau fractures: Assess patient first (general status, ATLS, compartments etc) Diagnosis Fracture pattern Degree of displacement Knee Joint position/disruption Leg Alignment Imaging, pre-operative planning, timing Hardware, surgical expertise, rehabilitation goals

9 Management decisions Operative vs non operative What degree of displacement can you accept? What is the patient like? Timing of surgery Soft tissue injury (bruising, swelling) What hardware? Why Which incisions? Minimally invasive? Fixation plans?

10 How can we influence outcome?

11 How can we influence outcome? Rehabilitation Treatment decisions Patient factors

12 How can we influence outcome? Patient factors Age, comorbidity Smoking,drugs Treatment decisions Conservative Surgical fixation Rehabilitation Cast,Brace, ROM Early ROM

35 Rehabilitation Delayed Early ROM

36 So what outcomes are we getting?

37 Outcomes 49 pts, <40 no difference, >40 worse outcome 311 pts, 10 yr follow up. 13% had TKR 125 pts, < 10 yrs follow up. 26% OA on XR, 4% TKR
