Section snippets
Methods
A consecutive series of patients with the diagnosis of cam FAI treated with arthroscopic proximal femur reshaping was prospectively studied with a minimum follow-up of 2 years. Patients that presented an impingement deformity dependent on the acetabulum such as coxa profunda, acetabular retroversion, or acetabular deformity secondary to osteotomy (iatrogenic impingement) belong to the pincer FAI classification. Pincer FAI cases were not included in this study. Patients that presented a pincer
Results
Between January 2003 and June 2004, we performed 19 hip arthroscopies in 19 patients for cam-type FAI with unilateral disease (Table 1). We had 11 male and 8 female patients with an average age of 34 years (range 27-43). Twelve hips were right and 7 left. All the patients complained of pain in the groin related to physical activity and presented limited internal rotation with pain. They also complained of occasional mechanical hip symptoms (locking and catching of the hip joint). Cam-type
Discussion
Anatomic deformity has been described as an important etiology of hip osteoarthritis [1]. Leunig et al have made significant contributions in the description and treatment of FAI and its relation with hip osteoarthritis [3]. More recent developments have made hip arthroscopy a very attractive alternative in the treatment of FAI 5, 6. These developments are so new that the techniques are evolving as more experience is gained.
Beck et al [14] reported the results of open treatment of cam FAI in 19
