OBJECTIVES: Images of acetabular deficiency in Crowe type 2 developmental dislocated hips were evaluated by computed tomography (CT) and acetabular component was placed surgically.
PATIENTS AND METHODS: Twenty-nine hips of 18 patients (2 males, 16 females; mean age 46 years; range 37 to 56 years) have been reviewed through CT imaging. The roof edge angle, the acetabular index of depth to width and bone mass of the anterior and posterior acetabular rim have been measured over the cross sections obtained from the CT.
RESULTS: Acetabular structure was normal in four hips, and there was no posterior rim deficiency in any hips. However, there was anterior rim deficiency in 21 hips, and there was both posterior and anterior deficiency in four hips. The acetabular anteversion was the most common finding.
CONCLUSION: In this study, increased acetabular anteversion and anterior rim deficiency were frequently observed in patients with Crowe type 2 hip dislocation. An orthopaedist should consider anteversion and this deficiency when fitting acetabular component.
