Rajasbala Dhande, Akhita Singhania, Suvarn Gupta

Abstract :

OBJECTIVE: To assess the role of MRI in cases of AVN of femoral head and evaluate its sensitivity for the same.

MATERIAL AND METHODS: 50 patients with clinical suspicion, were examined by 1.5 tesla MRI, using T1WI, T2WI and STIR sequences in axial, coronal and sagittal planes.

RESULTS: study comprised of 48 patients suffering from avascular necrosis (71 hip joints). Maximum patients belonged to age group 31-40 (28.5%). 32 (76.19%) patients were males and 10 (23.8%) were females. Bilateral AVN was detected in 29 (69.04%) and unilateral in 13 patients (30.9%). Pre collapsed stage (Stages I and II) was detected in 22 hips (30.9%), collapsed stage (Stages III and IV) was detected in 49 hips (69.01%). Double line sign on T2weighted image was seen in 40/71 (56.3%)

CONCLUSION: MRI is a sensitive for diagnosis and determination of extent of disease process. Early detection leads to early treatment and hence avoids unnecessary surgical interventions.
