Comparison of quadricep motor evoked potentials between different surgical positions during total hip arthroplasty
Authors' conclusion
Intraoperative quadricep motor-evoked potential monitoring in primary THA using the anterolateral approach showed significantly lower MEP amplitude in the supine position than in the lateral position at all three time points.
Study context
- Population
- Patients undergoing primary total hip arthroplasty (THA) using the anterolateral approach with intraoperative quadricep transcranial electrical stimulation MEP data, June 2021–January 2024
- Exposure
- Supine vs lateral position during THA via anterolateral approach
- Outcome
- Residual rate of quadricep MEP amplitude (amplitude at surgery start set to 100%)
- Follow-up
- After anterior acetabular retractor placement, after acetabular retractor placement, and before wound closure
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Residual rate of quadriceps MEP · all three time points
- Residual rates of quadriceps MEP significantly lower in the supine than the lateral position at all three time points
- Supine vs Lateral: P < 0.05
Observational data: associations, not effects.
Further findings
Patient background
- Did not differ significantly between the groups
Safety
- No postoperative paralysis observed
