Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Randomized to Internal Fixator

Patient signed consent and agreed to have their treatment method randomized and the randomization system determined that their surgical intervention would be internal fixator.

Group Type EXPERIMENTAL

Internal Fixator

Intervention Type PROCEDURE

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.

Randomized to Symphyseal Plate

Patient signed consent and agreed to have their treatment method randomized and the randomization system determined that their surgical intervention would be internal plating of the symphysis.

Group Type EXPERIMENTAL

Symphyseal Plate

Intervention Type PROCEDURE

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

Observational - Internal Fixator

Patient signed consent but did not want to randomize their procedure and the treating physician selected the internal fixator intervention based on their opinion of how best to treat the specific case.

Group Type ACTIVE_COMPARATOR

Internal Fixator

Intervention Type PROCEDURE

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 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
