Only one day after going on the DL with what was purported to be a muscle strain of the flexor tendons attaching at the inner elbow (medial epicondylitis), a contrast MRI revealed that Joba Chamberlain has a ligament tear that will likely require Tommy John surgery.

Though WFAN.com reported that Yankee brass professed surprised at the severity of the injury, when a pitcher has significant medial elbow pain, a tear of the ulnar (medial) collateral ligament (UCL) is generally suspected.

As discussed in yesterday’s Injury Breakdown post, symptoms of an Ulnar Collateral tear, medical eipcondylitis and  irritation  or entrapment of the ulnar nerve share many similarities.  When it is an overhead athlete doing the complaining – particularly a pitcher who must put repetitive stress on the inner elbow – a tear is one likely culprit.  What is remarkable however, is the success with which Joba pitched while injured.

Comparing these diagrams will help you to see the intimate relationship of the ulnar collateral ligament and the tendons that were initially suspected of causing Chamberlain’s pain..

Take a look at an Injury Breakdown post from August of 2010, on then 22-year-old Nationals phenom Stephen Strasburg, to learn more about UCL tears and the Tommy John procedure.
