Pelvis RCT: Impact of Surgery on Pain in Lateral Compression Type Pelvic Fractures

Not Applicable

Completed

Brief Summary: Lateral compression type pelvic ring injuries remain the most common type of pelvic fractures encountered. There is a substantial amount of controversy surrounding the treatment of these injuries and there is evidence that both operative and non-operative treatment can be successful.

Detailed Description: The crux of the problem is determining which of these patients would benefit from early surgical stabilization and which will heal uneventfully without surgery. Many authors site patient pain and inability to mobilize as indications for surgery, although there is conflicting evidence supporting this claim. The presence of chronic pain in the trauma population is a growing area of interest, and there is a push towards controlling pain more effectively in the acute setting. It remains to be proven that surgical intervention is more effective at decreasing acute and longer term pain.

There is evidence in the literature to support both operative and non-operative treatment of patients with LC1 or LC2 pelvic fractures. There is conflicting evidence that surgical stabilization decreases acute pain and narcotic requirements, although patients are often counseled to that effect. The investigators propose to prospectively randomize patients with lateral compression type pelvic fractures to non-operative versus operative treatment and track which group has less pain, less need for narcotic pain medications, and who mobilizes with physical therapy faster.

Recruitment & Eligibility

Inclusion Criteria

The patient has one of the following pelvic fractures (includes bilateral sacral fractures): Lateral compression type 1, Lateral compression type 2, Lateral compression type 3
The patient is between 18 and 80 years of age, inclusive
The patient has reached skeletal maturity
The patient's pelvic fracture is a result of trauma (includes polytraumatized patients)
The patient/family/guardian is English-speaking
The patient's surgeon agrees to randomization (the patient is amendable to either operative or non-operative treatment)
Patient enrollment and, if applicable, patient randomization can occur within 96 hours post injury

Exclusion Criteria

The patient has prior surgical hardware in place that precludes intervention
The patient's pelvic fracture is classified as a Lateral compression type 1 and the associated sacral fracture is incomplete as indicated by failure to violate both the anterior and posterior cortex
The patient received prior surgical intervention for his/her current pelvic injury
The patient has sacral morphology that precludes percutaneous fixation
The patient is non-ambulatory due to an associated spinal cord injury
The patient was non-ambulatory pre-injury
The patient is currently pregnant
The patient is enrolled in another research study that does not allow co-enrollment
The patient is likely to have severe problems with maintaining follow-up

Primary Outcome Measures

Name	Time	Method
Posttreatment Pain	up to 12 weeks post injury	The primary outcome was patient-reported pain severity, as measured by the mean of the 4 pain severity items of the Brief Pain Inventory (BPI): worst pain in the last 24 hours, least pain in the last 24 hours, pain on average, and pain right now. The BPI uses a 0-10 level visual analog scale (VAS) with a 24-hour recall period, where 0 anchors "no pain" and 10 anchors "pain as bad as you can imagine." The minimum clinically important difference (MCID) is not definitively established for the BPI in a trauma population; however, the MCID for other 10-point VAS pain scales has been reported between 1.0-2.5 points.

Secondary Outcome Measures

Name	Time	Method
Length of Hospitalization	through patient discharge, up to 12 weeks post injury	Length of hospitalization is determined by recording the admission date versus discharge date for the patient's index hospitalization stay.
Posttreatment Function	up to 12 weeks post injury	Secondary functional outcome was measured by the Majeed pelvic score. The Majeed pelvic score is a seven-item patient-reported outcome instrument that measures pain, work status, sitting comfort, sexual intercourse, use of walking aids, gait disturbance, and walking distance. The score is reported as a percentage of the highest possible score to adjust for participants who were not employed before their injury. Higher scores represent better function, and a score of \>85% has been suggested to represent excellent function.
Time to First Mobilization Post Injury	through patient discharge, up to 12 weeks post injury	Time to first mobilization (bed to chair) is determined using the physical therapy notes during the patient's index hospitalization and is recorded as the number of days post injury that mobilization first occurred.
