Methods
The present study was a retrospective review of clinical cases. Between April 1995 and June 2003, the same author (Y.Y.) examined a total of 95 hip joints with snapping hip accompanied by pain, at the Department of Orthopedic Surgery, University of Yamanashi Faculty of Medicine and Ichikawadaimon Municipal Hospital. The criteria of snapping hip were (1) a patient could consistently reproduce snapping with active hip motion and (2) the examiner could confirm the clicking sound or palpate
Results
Plain radiographs showed no abnormality in 11 joints, osteoarthritis of the hip in 19 joints, femoral head deformation caused by Perthes disease in 1 joint, and synovial osteochondromatosis in 1 joint. MRI and arthrography were conducted in 31 joints (the joint with synovial osteochondromatosis was not imaged). MRI failed to show any findings that might be considered as the cause of snapping in all cases. Hip arthrography identified an intra-articular loose body in 2 joints with osteoarthritis.
Discussion
The causes of intra-articular type snapping hip have been mentioned in a few reports. Freich et al.4 in 1989 and Atlihan et al.5 in 2003 reported the synovial plica; in 1998, Bellabaraba et al.7 reported joint instability; and in 2004, we11 reported impingement of detached cartilage fragment as a cause of snapping hip. In 1995, McCarthy and Busconi6 reported that, based on arthroscopic findings of coxalgia with unknown cause, 31 of 33 joints manifesting snapping were caused by acetabular labral
Conclusions
- 1
Incompatibility between the acetabular labrum and a deformed femoral head was found to be a cause of intra-articular type snapping hip.
- 2
Acetabular labral tear was the cause of 80% of the cases of intra-articular type snapping hip.
- 3
Local injection of anesthesia into the hip joint together with arthroscopy is very useful for establishing the diagnosis of intra-articular type snapping hip.
- 4
Arthroscopy is extremely useful in the surgical treatment of intra-articular type snapping hip.
