Hip Arthroscopy for Femoral Acetabular Impingement: A Bird's-Eye/En Face Perspective With Ultrasound Guidance and 3-Dimensional Hip Printing

Femoral acetabular impingement is a common hip disorder that may prove debilitating to many patients. Surgical management is indicated by way of hip arthroscopy for impinging CAM and pincer acetabular lesions. Traditionally, fluoroscopy has been used for the intraoperative assessment of bony resection; however, many disadvantages include radiation risks, equipment demands, and more. With ultrasound-guided arthroscopy, we describe the use of 1:1 3-dimensional hip printed models through various visual perspectives of impinging lesions. Given the low cost of 3-dimensional hip printing, lack of radiation exposure, and tactile multiangular views, we propose a safer and more reproducible intraoperative technique to conventional fluoroscopy to achieve better resection and outcomes after femoral acetabular impingement surgery.
