Hello,
I am assuming that you are asking for state quota in West Bengal. West Bengal has only 8 orthopaedic seats and it is very difficult to get a seat. According to last year's cutoffs the last rank for ms (orthopaedics) in the unreserved category was 9751 admitted in KPC medical college. The rank for diploma in orthopaedics was 12,431 in Medical College, Kolkata. So, it seems difficult for him to get orthopaedics. However, he can try for ophthalmology, anaesthesia, pharmacology, pathology, community medicine or diploma in O. B. G. He can also try for management seats in which case he can get general medicine, orthopaedics, surgery.

Hope this helps.

With this rank, if you are looking within West Bengal, then General Surgery and Orthopaedics are tad difficult. He has decent chances in Anatomy, Physiology, Anaesthesiology, Community Medicine, etc. But if you are looking at All India Level, then he has chance at:

Aurangabad Medical College

Amrita Institute of Medical Sciences

Shri Siddartha Medical College, Tumkur

Loni Medical College

Hegde Medical College, etc.
