Abstract: Background: Coxa profunda or deep acetabular socket is a variant of cam type of femoroacetabular impingement (FAI). It is a common radiographic finding in patients with painful hip which is often missed. The diagnosis of this condition plays a vital role in the approach towards the treatment and functional outcome of the treatment. The purpose of this study is to determine the prevalence of coxa profunda. Materials and Methods: In this study a total of 117 pelvis with bilateral radiographs out of which 77 patients with positive radiographic findings for coxa profunda are analysed retrospectively. The study was done at R.L. Jalappa Hospital and Research Centre, Tamaka. Kolar. Patients with positive radiographic findings are called and taken thorough history and examination done to know whether patients are symptomatic or not. Results: Among 117 patient radiographs taken for the study 77 patients are diagnosed with coxa profunda. The results were analysed on clinical findings like positive stress test for pincer type of femoroacetabular index and also parameters like medialization of floor of fossa acetabuli, increase in lateral centre edge angle(CE), decrease in acetabular index (tonni’s angle),decrease in femoral head extrusion index, femoral acetabular over coverage are taken into consideration for the diagnosis of this condition. Conclusion: Coxa profunda is a common variation of pincer type of femoroacetabular impingement which is often missed.
