Zack Cozart, CIN (Right elbow hyperextension) [AGL: 26, ATD: +.025] (Explanation)
The elbow is actually composed of three different joints, but the major joint is a hinged joint that forms between the humerus and ulna. The main movements of the humeroulnar joint include flexion and extension, although there is some circumduction motion as well. When the elbow hyperextends, several structures—the biceps, brachialis, joint capsule, and other structures—stretch and can tear, leading to dislocations in severe cases.
For right-handed hitters, hyperextension injuries of the left elbow can be slower to return from than one would expect. With every swing, the momentum of the bat carries the elbow into extension, often moving into slight hyperextension for a brief moment. The risk of re-injury if Cozart were to come back at less than 100 percent is fairly high. Cozart was placed into a metallic brace that limits his range of motion, along with a sleeve to help deal with the pain and swelling. He will use the next few weeks to calm down the inflammation and swelling with modalities and limited range of motion before progressing to strengthening exercises.
J.D. Drew, BOS (Left shoulder impingement) [AGL: 29, ATD: +.113]
Internal impingement is a difficult injury to deal with because of the contributing factorsand the nature of the sport. It's a complicated condition to fully grasp, even for medical professionals, but summing it up briefly:during the late cocking phase of the delivery,the postero-superior labrum gets pinched between the humeral head and the rotator cuff, specifically the infraspinatus and some of the supraspinatus. Anti-inflammatory medication and physical therapy are prescribed,but the injurycan be slow to respond.
In subacromial impingement, the supraspinatus tendon—one of the rotator cuff muscles—and bursa becomepinched between the humeral head and the undersurface of the AC joint. Poor posture is often a major contributor to the pain,as is overuse of the shoulder. This is much easier to treat with anti-inflammatory medication and physical therapy than internal impingement.
Drew will be on the shelf for a few weeks, and given how the Red Sox are playing right now, it appears that they can handle his absence.
Adrian Beltre, TEX (Left hamstring strain) [AGL: 27, ATD: -.007]
Kyle Lohse, STL (Right middle finger inflammation) [AGL: 5 (36DL), ATD: +.008 (+.004DL)]
Luke Scott, BAL (Right shoulder labrum tear) [AGL: 73, ATD: +.026]
Cameron Maybin, SDN (Strained left hip flexor) [AGL: 2 (27DL), ATD: -.031 (+.023DL)]
Flesh Wounds: J.J. Putz and his inflamed right elbow should be activated on Tuesday... Geoff Blum fractured his right pinkie finger fielding a ball yesterday. No word yet on whether or not he will end up on the disabled list... Angel Pagan left Sunday's game with dehydration. Once he replenishes his fluids, he should be able to return to the lineup... Orlando Hudson was available off the bench yesterday, two days after being unconscious for a period of time. He still has lingering headaches and sore shoulder/neck muscles, but he cleared neurological testing... Jose Contreras was given a PRP injection on Friday to complement his other non-surgical treatments. He will be out for several more weeks... Placido Polanco is feeling much better following his epidural injections... Jed Lowrie has increased his hitting intensity recently and is progressing nicely. He is still a few weeks away at the earliest, however... Joe Blanton will be checked out for nerve damage on Tuesday... Gerardo Parra was hit by a pitch on the left wrist on Saturday and did not start on Sunday. He may need a few more days to recover.
