Detailed Description
Periarticular fractures (bone breaks extending into the joint surface) treated by orthopaedic surgeons are associated with significant pain in the post-operative period, often requiring high doses of opioid analgesics. In recent years, the high risk of misuse, abuse, and death associated with prescription opioid use has become increasingly evident.
Although physicians are being advised to avoid administration of opioid prescriptions, alternative pain management options are limited. Currently, there is a need to investigate different pain management models in order to provide safe and effective pain relief during the post-operative period. The investigators aim to evaluate the effectiveness of peri-incisional multimodal injections as an alternative post-operative pain control method in orthopaedic trauma patients with operative ankle fractures. Approximately 200 patients will be randomized to either receive or not receive intra-operative injections in addition to standard opioid analgesic regimens. Post-operative pain management outcomes will be assessed and compared between the 2 study groups to determine effectiveness of the injections. The proposed study will build upon related work to advance post-operative pain control regimens in orthopaedic surgery. Goals include the reduction of unnecessary patient suffering, reliance on opioids, and length of stay, while improving patient experience. These aims will be accomplished through the expansion of currently used multimodal periarticular injections from populations undergoing elective surgery to orthopaedic trauma patients with rotational ankle fractures.
The study design is a prospective, double-blinded, randomized controlled trial. Patients included in the study will be randomly assigned to one of two treatment groups: intra-operative multimodal periarticular injection or control (no injection). The peri-incisional injection will consist of ropivacaine, epinephrine, and morphine. All pharmacologic agents in the anesthetic cocktail are FDA approved and have been previously used in combination during other types of orthopaedic surgeries.
All patients included in the study will receive standard post-operative opioid analgesic regimens, administered 'per needed', regardless of their assigned treatment group per study protocol. ≥ 40 patients will be randomly assigned to each group. The patients enrolled in the investigation as well as health care professionals performing post-operative assessments and collecting data will be blinded to treatment allocation. The feasibility of multimodal peri-incisional injections is supported by their current efficacy in populations undergoing elective orthopedic surgeries. These injections may be equally effective at reducing pain compared to regional anesthesia with continuous infusions, and single-shot nerve blocks.
The investigators hypothesize that the injection cohort will have reduced pain scores, lower narcotic requirements, shorter length of stay, and be more likely to discharge to home following surgery.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Peri-incisional injection
A single, 25 cc multimodal analgesic cocktail will be injected following completion of ankle fracture fixation/instrumentation while the patient remains under general anesthesia and prior to skin closure. The injection will be administered as such:
Interventions: Drug: Ropivacaine Drug: Epinephrine Drug: Morphine Drug: 0.9% sodium chloride solution Following surgery, patients in the treatment and non-treatment groups will both be provided with the same intravenous (patient-controlled analgesia) and oral pain medications scheduled "per needed". |

No Intervention: Control
Ankle fracture fixation/instrumentation will be completed per the standard of care.
No peri-incisional injection will be completed.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Post-operative Visual Analog Pain Scores (VAS)
Time Frame: Immediately following surgery, then every 4 hours following surgery for 48 hours post-surgery.
|
The primary outcome was VAS pain over the first 48 hours postoperatively.
Patients reported pain with use of a 100-mm VAS, with 0-mm being no pain and 100-mm being the most extreme pain imaginable.
A higher score indicates worse pain.
Scores were reported as mean values at 24 hours post-surgery and 48 hours post-surgery.
|
Immediately following surgery, then every 4 hours following surgery for 48 hours post-surgery.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Opioid Use in First 24 Hours Post-surgery
Time Frame: At 24 hours post-surgery & during the total time of inpatient stay to dischage
|
Total opioid consumption expressed in morphine equivalent dose will be recorded, including IV and oral opioids, in the first 24 hours post-surgery.
|
At 24 hours post-surgery & during the total time of inpatient stay to dischage

Post-operative Length of Stay
Time Frame: From immediately following surgery to 90 days after.
|
Number of days in the hospital following surgery
|
From immediately following surgery to 90 days after.

Patients Returning Home Following Surgery
Time Frame: Following hospital discharge from surgery

Other Outcome Measures

Medication-related Side Effects
Time Frame: From immediately following surgery to 7 days after.
|
Patients will be monitored by nursing personnel for medication side effects related to ropivacaine toxicity including blurred vision, hearing problems, transient peripheral paralysis, dizziness, convulsion, uncontrolled muscle contraction, hypotension, bradycardia, and new onset arrhythmia.
|
From immediately following surgery to 7 days after.
