NCT04097678

Brief Summary

This prospective study will determine the efficacy of intraoperative x-ray to identify retained surgical sponges. The recommended practice for finding a retained sponge is by radiography. The purpose is to find out how useful plain x-rays are in open posterior lumbar spine surgery, information which is presently unavailable. The specific aim is to compare the sensitivity (seeing a sponge when one is actually present) and specificity (not seeing a sponge when one is not present) of radiography of the surgical field for three conditions: viewing one lateral radiograph versus viewing one anteroposterior radiograph versus viewing two radiographs together, one lateral and one anteroposterior.

Outcome Measures

Primary Outcomes (5)

  • Accuracy

    Reviewer accuracy is the agreement (Cohen's Kappa) between the true condition and the readers' interpretation with 1) one lateral (LAT) image, 2) one anteroposterior (AP) image, and 3) AP and LAT images together.

    Intraoperative

  • Interobserver Reproducibility

    Interobserver Reproducibility is the agreement (Cohen's Kappa) between observers interpretations

    Intraoperative

  • Intraobserver Reproducibility

    Intraobserver Reproducibility is the agreement (Cohen's Kapp) of an observer with himself

    Intraoperative

  • Sensitivity

    Sensitivity is the percentage of all images appearing to have a sponge in which a sponge was truly present

    Intraoperative

  • Specificity

    Specificity is the percentage of all images appearing to not have a sponge in which a sponge was truly not present

    Intraoperative

Study Arms (2)

Retained Sponge Group

EXPERIMENTAL

Just prior to imaging, the surgeon will purposely place a sponge in the wound. Two radiographs will be taken of the spine (AP and Lateral views).

Other: Retained Surgical Sponge

No Retained Sponge Group

NO INTERVENTION

No sponge will be placed in the wound. Two radiographs will be taken of the spine (AP and Lateral views).

Interventions

A surgical sponge will be intentionally placed in the surgical field prior to final imaging and then removed. Postoperatively, images will be assessed for the presence or absence of a retained surgical sponge.
