Summary
This study presents a novel technique using a deflated beanbag for hip arthroscopy, reducing the risk of pudendal nerve palsy. This method ensures patient stability and optimal surgical visualization without compromising ventilation.
Area of Science:
- Orthopedic Surgery
- Surgical Complications
- Neurophysiology
Background:
- Pudendal nerve palsy is a known complication associated with hip arthroscopy.
- Traditional patient positioning methods may contribute to this neurological deficit.
Purpose of the Study:
- To describe an alternative patient positioning technique for hip arthroscopy.
- To minimize the risk of pudendal nerve palsy during hip arthroscopy.
Main Methods:
- A deflated, taped beanbag is used for patient support instead of a perineal post.
- The beanbag is contoured to the patient's flank and thorax, secured with tape to the operative table.
- Careful placement avoids compression of the axillary region and posterior humerus, ensuring ventilation and surgical field access.
Main Results:
- The described technique provides adequate stability for traction and visualization during hip arthroscopy.
- This method effectively minimizes the risk of pudendal nerve palsy.
Conclusions:
- The deflated taped beanbag technique offers a safer alternative for patient positioning in hip arthroscopy.
- This approach enhances patient safety by mitigating the risk of specific nerve injuries.
