Anterior Pelvic Ring Injury With Symphysis Disruption

Keywords

anterior pelvic ring, symphysis disruption

Brief summary

The purpose of this study is to compare subcutaneous internal fixation and open plating of the symphysis in patients with a disruption of the symphysis requiring stabilization.

Detailed description

The aim of this study is to determine whether either one of the two procedures has significant advantages over the other. The null hypothesis of this study is that there is no difference between plating and subcutaneous internal fixation of symphysis disruptions with respect to primary and secondary outcomes. The study is a randomized trial with patients who sustained a symphysis disruption who will randomize to either closed reduction and subcutaneous internal fixation, or open reduction and plating of the symphysis. There will also be two observational arms of the study, patients who do not agree to randomization and will receive internal fixation according to the treating surgeon's discretion and patients with a symphysis disruption that do not require any form of anterior pelvic internal fixation based on the treating surgeon's opinion. Clinical assessments will occur at the time of hospital admission and at all post-operative follow-up intervals (2 weeks, 6 weeks, 3 months, 6months, 12 months, and 24 months).

Interventions

Internal fixator refers to pins usually inserted into the iliac bones and then connected together by clamps and bars that are inserted under the skin, internally.

PROCEDURESymphyseal Plate

A plate that spans across the symphysis to maintain reduction and stability.

Inclusion criteria

* A symphysis disruption either in the coronal and/or sagittal plane on anterior-posterior , inlet and/or outlet pelvic radiographs * Need for anterior pelvic ring stabilization * Injury amenable to plating as well as subcutaneous internal fixation per the treating surgeon's opinion * Patient was ambulatory prior to sustaining the injury * Provision of informed consent by patient or proxy

Exclusion criteria

* Patients with a slim build with little subcutaneous fat who cannot be treated with a subcutaneous internal fixator based on the treating surgeon's opinion * Patients who are deemed not likely to follow-up (e.g. patients who live more than 50 miles away and patients with no fixed address) * Moderately or severely cognitively impaired patients * Pregnant women * Prisoners

Design outcomes

Primary

MeasureTime frameDescription
Functional Outcomes24 hours - 24 monthsThe primary objective is to compare functional outcomes between subcutaneous internal fixation and symphyseal plating as measured by the PROMIS v1.2-Physical Function instrument.

Secondary

MeasureTime frameDescription
Compare the health-related quality of life and functional outcome scores24 hours - 24 monthsWe will ask patients multiple questionnaires to assess their quality of life after surgery. These questionnaires include: PROMIS v1.1 - Pain Interference, PROMIS v1.2 - Mobility, PROMIS v1.0 - Global Satisfaction with Sex Life, PROMIS v1.0 - Depression, Majeed score, SF-12, VAS, patient satisfaction score, time to return to work, revision surgery, use of assistive walking devices, length of hospital stay, and for me, PROMIS v1.0 - Erectile Function.
