''Compare Abdominal Crunch Positions With Conventional Sitting and Lateral Decubitus Positions in Terms of Interspinous Distance in Adult Patients''

The most important factor for ease of operation and safety during spinal anesthesia is the determination of the spinal space. Increasing lumbar flexion facilitates access to the spinal space. Traditionally, patients undergo spinal anesthesia with lateral or sitting lumbar flexion.

In a study by Martha L Walker et al., The maximum extension of the knees, adduction of the hip, and a modified sitting position with the back flexion, ie, the abdominal crunch position, were found to be effective in increasing the flexion of the lumbar spine.

In our study, we aimed to measure the interspinal distance with the abdominal crunch position with the help of ultrasonography (USG) and to compare the interspinal distance with the measurements obtained in traditional positions (sitting position and lateral decubitus).
