These are my personal notes on various MSK topics. I have tried to organise them into categories. Although I have taken care to make my blog posts as accurately as possible, the blog itself is not replacement for text-books and journals. The blogger does not accept any harm or injury related to the use of the material from this blog. All the images are from my collection and are not copyrighted; hence feel free to use them and I do not want any credit also. The written material is basically notes from the quoted journals and text books, relevant to my practice. If anybody feels I am violating copyright, please let me know. I will delete the relevant data from my blog.

I am greatly indebted to these two books for my musculoskeletal radiology practice. Unless mentioned otherwise, most of notes in this blog are from 2 main text books, :
1. David W Stoller. MRI in orthopaedics and sports medicine. 3rd edition. Lippincott Williams and Wilkins publications. 2007.
2. Resnick et al. Internal derangements of joints. 2nd edition. Saunders Elsevier publications. 2007.
