knee/hip arthroplasty
Conditions
Interventions
Preoperative Ultrasound Localization Group: During preoperative ultrasound-guided puncture, the operator used ultrasound to estimate the puncture point and the distance from the skin to the epidural s
Flexion Lateral Decubitus Radiography Group:Before puncture, flexion lateral decubitus lumbar X-ray plain films were taken to select the target intervertebral space, estimate the needle insertion angl
Surface Anatomical Landmark Group:The needle insertion point was estimated by palpating anatomical landmarks.
