Low-Molecular-Weight Heparin (LMWH) for Deep Venous Thrombosis (DVT) Prophylaxis

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

  1. The use of LMWH following open reduction and internal fixation of ankle fractures will reduce the number of thrombi formed.
  2. The rates of clinically significant DVT will be equivalent between two groups.

Condition Intervention
Deep Venous Thrombosis Drug: Low-Molecular-Weight Heparin

Study Type: Interventional
Study Design: Allocation: Non-Randomized

Further study details as provided by University of Tennessee:

Primary Outcome Measures:
  • We will compare the rates of thrombi formation between the two groups. We will record any clinical significant thrombi or complications that arise from thrombi. We will record any complications related to administration of LMWH. [ Time Frame: first post-operative office visit (usually 10-14 days) ]

Secondary Outcome Measures:
  • We may find that there is in fact significant benefit to giving prophylaxis to this subset of patients in the form of decreased rates of throb\mbus formation and the complications related to thrombi. The risk/benefit ratio should be favorable. [ Time Frame: first post-operative office visit (10-14 days) ]

Estimated Enrollment: 100
Study Start Date: February 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Low-Molecular-Weight Heparin for DVT
Low-Molecular-Weight Heparin for DVT Prophylaxis after Open Reduction and Internal Fixation of ankle fractures
Drug: Low-Molecular-Weight Heparin
Isolated Ankle Fracture Single planned operation

Detailed Description:
Routine use of thromboprophylaxis may be over treatment and definitely increases healthcare costs. While prophylaxis may reduce the number of thrombi formed the exact number and clinical significance of these is unknown. This study seeks to answer the question of whether or not DVT prophylaxis with low-molecular-weight heparin (LMWH) following ORIF of ankle fractures is warranted.
