Location and Radiological Features of the Synovial Pit and Its Usefulness in Hip Arthroscopy

Main Article Content
Abstract
Materials and Methods: A total of 388 hip arthroscopies performed between 2018 and 2023 were included. Radiographs and complementary imaging studies were analyzed to classify morphological abnormalities and describe synovial pit characteristics. Measurements included the lateral center-edge angle, acetabular index, and alpha angle.
Results: In patients with predominantly femoral abnormalities, impingement tended to occur more proximally, and the synovial pit was located in that region; conversely, when acetabular abnormalities predominated, impingement occurred more distally. No other variables reached statistical significance.
Conclusion: The presence and features of the synovial pit in preoperative imaging, as well as its intraoperative identification during hip arthroscopy, may provide additional insight into the mechanisms of femoroacetabular impingement and its biomechanics.
