Anatomical Positions

17.1K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Summary

Pelvic incidence (PI) can decrease on the operating table in patients undergoing lumbar posterior spine surgery. This PI change is linked to worse preoperative spinal alignment, impacting surgical planning.

Area of Science:

  • Spine surgery
  • Radiographic analysis
  • Pelvic parameters

Background:

  • Pelvic incidence (PI) changes after long spine fusion surgery are documented.
  • No prior studies have investigated PI changes occurring specifically on the operating table.
  • Understanding intraoperative PI shifts is crucial for surgical decision-making.

Purpose of the Study:

  • To examine the change in pelvic incidence (PI) on the operating table.
  • To identify patient characteristics associated with intraoperative PI changes.
  • To correlate PI changes with preoperative radiographic parameters.

Main Methods:

  • Retrospective analysis of patients undergoing lumbar posterior spine surgery.
  • Comparison of preoperative standing radiographs with intraoperative pelvic lateral radiographs in prone position.
  • Classification of patients into groups based on PI change on the operating table (PICOT group) versus no significant change (control group).

Main Results:

  • 12.5% of patients (16 out of 128) exhibited a PI decrease >10° on the operating table (PICOT group).
  • The PICOT group showed significantly worse preoperative lumbar lordosis (LL) and PI-LL compared to the control group.
  • While the PICOT group had a higher proportion of fusion surgeries, this difference was not statistically significant.

Conclusions:

  • A decrease in pelvic incidence (PI) can occur intraoperatively in patients undergoing lumbar posterior spine surgery.
  • Patients experiencing an intraoperative PI decrease demonstrate poorer preoperative global spinal alignment.
  • These findings highlight the importance of assessing PI in the operating room for surgical planning.
