Subscapularis muscle. Supraspinatus muscle. Structure[edit] The supraspinatus muscle arises from the supraspinous fossa, a shallow depression in the body of the scapular above its spine.
The supraspinatus muscle tendon passes laterally beneath the cover of the acromion. Research in 1996 showed that the postero-lateral origin was more lateral than classically described.[1][2] Playing with a torn biceps tendon. If you are a fan of baseball, you know that we are well into the playoffs.
My Dad asked me a question the other day that I thought would make a good blog post. His question was how could Edgar Renteria, a shortstop for the San Francisco Giants, continue to play with a torn biceps tendon? This is a good question, and from media reports, it seems Renteria tore the tendon in his left biceps brachii while swinging at a pitch against the Braves last week. The biceps brachii is the large (well, large in some people) muscle located on the anterior (front) part of the upper arm. There are actually two parts to the biceps brachii, as biceps means two heads. Rotator cuff tears: cables and crescents?
So a tear of the rotator cuff is pretty disastrous, right?
It means surgery, right? Well NO it doesn't! As our understanding and knowledge of the shoulder joint improves so does our ability to recognise those cuff tears that are going to do ok without the need for surgery, let me explain more. It has been well known in the medical world for quite sometime that there are a lot of people out there with tears in their rotator cuff tendons functioning normally with no pain and not even aware of them, for example Templhof et al back in 1999 published a study that looked at the shoulders of people with no pains or reported problems, and 23% of them had cuff tears! Thats nearly 1 in 4 of us could have a cuff tear! So why is this? Well first we need to look at where and what is torn in the rotator cuff. For example our superior rotator cuff (where most tears occur) is best thought of as a suspension bridge!

As we discussed in another post today, failure of the polyethylene glenoid component is the most common complication of total shoulder arthroplasty. Concern about glenoid component failure leads surgeons to place long-term activity restrictions on their patients. In an effort to meet the demands of individuals wishing for high levels of physical activity after shoulder arthroplasty without concern about glenoid component failure we have explored the application of non-prosthetic glenoid arthroplasty with humeral hemiarthroplasty – the ream and run procedure. This procedure is technically exacting and requires the vigorous and full participation of the patient during what can be a lengthy rehabilitation process. We have summarized some of the ream and run essentials here. (1) Surgical Approach-After administration of prophylactic antibiotics. Subscapularis.
