Determining the cost effectiveness, based on the time duration of application, of two methods of wiring the jaws together during surgery to repair mandible fractures. One technique is more expensive but faster in application, while the other is less expensive and takes more time to apply.

Condition Intervention
Mandible Fracture Device: IMF Screws Device: Erich Arch Bars

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Other
Official Title: Erich Arch Bars vs. IMF Screws for Placement of Maxillomandibular Fixation: Which is More Time Effective in the Operating Room Setting?

Further study details as provided by Daniel Meara, Christiana Care Health Services:

Primary Outcome Measures:
  • Time [ Time Frame: Time duration of placement of device in operating room ]
    Time duration for the application of device, in minutes.

Enrollment: 5
Study Start Date: July 2013
Study Completion Date: April 2015
Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: IMF Screws
Use of IMF screws as a means to wire the jaws.
Device: IMF Screws
stainless steel screws placed in bone
Other Name: Synthes IMF screws
Active Comparator: Erich Arch Bars
Use of Erich Arch bars in the wiring of the jaws.
Device: Erich Arch Bars
Surgical braces wired around teeth

Detailed Description:


To identify which option of wiring the jaws together during treatment of mandible fractures is more cost effective to the patient, Erich arch bars or IMF (Intermaxillary Fixation) screws. Patients who sustain mandible fractures that meet the inclusion criteria will be randomized to one of the two treatment types listed above. The overall treatment in both categories is consistent with the standard of care, the only difference being the method utilized to achieve intermaxillary fixation during the course of the surgery.
