Switched to observational study type.

The primary purpose of this study is to determine if perioperative glucocorticoid administration (IV intra-operative followed by a post-operative oral taper course) improves post-operative range of motion in a patient population that has sustained an intra-articular elbow fracture(s) (radial head, proximal ulna, distal humerus, or combined) that required operative fixation.

Elbow fractures are complex injuries that often involve the articular surface, are in close proximity to critical neurovascular structures, and are prone to post-operative complications. Complications following treatment of intra-articular elbow pathology can affect over 50% of patients and up to 30% of all patients will require a re-operation. One of the most common complications is joint stiffness.1 When a flexion arc of motion is diminished to less than 100 degrees, a flexion contracture is present greater than 30 degrees, or forearm rotation is less than 100 degrees, functional limitations are frequently present and further treatment may be recommended.2,3 In fact, contracture release may be required in 12-20% of patients after intra-articular elbow fractures and carries a relatively high complication rate when performed.

The relationship of post-traumatic elbow contracture to intra-articular fractures is well established and can caused by extrinsic factors such as heterotopic ossification (HO), fibrosis and capsular thickening, or by intrinsic factors such as failure of nonunion, malunion, arthrosis, or loose bodies.2,4 Recent studies analyzing the acute phase synovial fluid cytokine profile after an intra-articular elbow fracture have shown proinflammatory and catabolic factors in high concentrations that can lead to contracture through myofibroblast differentiation and proliferation.4 Furthermore, HO can limit range of motion in up to 40% of fractures and may also result from prolonged inflammation with elevated IL-1β and TNF-α levels.

The purpose of this study is to determine if perioperative glucocorticoid administration (IV intra-operative followed by a post-operative oral taper course) improves post-operative range of motion in a patient population that has sustained an intra-articular elbow fracture(s) (radial head, proximal ulna, distal humerus, or combined) that required operative fixation.

Primary Study Questions

1. For adult patients (>18yo) who sustain intra-articular elbow fractures (radial head, proximal ulna, distal humerus, or combined) that undergo operative fixation, does perioperative glucocorticoid administration (IV intra-operative followed by a post-operative oral taper course) improve post-operative range of motion (flexion/extension and pronation/supination) compared to a placebo?

   Secondary Study Questions

2. Is perioperative glucocorticoid administration more effective in improving range of motion for certain intra-operative elbow fractures or depending on the mechanism of injury (subgroup comparison based on fracture type and high-energy or low-energy injuries)?

3. Do patients that receive perioperative glucocorticoids have a higher surgical site infection rate?

Inclusion Criteria

• All adults ≥18 years old with an isolated, intra-articular traumatic elbow fracture to be treated at Vanderbilt University Medical Center with operative intervention and a standardized post-operative rehab protocol.

• Intra-articular elbow fracture defined as:

  • Distal humerus
  • Proximal ulna
  • Radial head fracture
  • Combination fracture of two or more of the above

• Radiographs present confirming intra-articular injury

Exclusion Criteria

• Patients with bilateral elbow fractures
• Patients with an altered mental status
• Pregnant
• Allergy or contra-indication to glucocorticoid administration
• Type 1 or Type 2 diabetes
• Pre-injury limitation in elbow range or motion (patient reported)
• Unable to provide consent for themselves

There were no participants randomized to the control arm.

6 Months

Serious Adverse Event- Any untoward medical occurrence that results in death or is life-threatening, results in persistent or substantial disability or incapacitation, results in inpatient hospitalization, or prolongation of an existing hospitalization, or requires medical or surgical intervention to prevent any of the previously mentioned outcomes as a result of this research.

Adverse Event Collection- An adverse event log was completed at each post-operative timepoint by study personnel.

The study was terminated early and converted to a non-interventional, observational study model. Of the 3 participants consented prior to termination, only 2 were randomized to a treatment arm and only 1 completed study procedures.

The treating physician and patient will be blinded to the treatment assignment.
