This is an 11-month-old Bernese Mountain Dog. He has a fragmented medial coronoid process (FMCP) in his right elbow.

This is a common condition in this breed. The displaced fragment (DF) can be seen in the arthroscopic image above. The adjacent bones are the medial coronoid process (MCP) and the radial head (R). This fragment was removed with small instruments inserted into the joint while visualizing the joint with an arthroscope. There is a small camera inserted into the joint and imaged on a computer monitor. This allows for minimal surgical trauma and a rapid recovery.
