in a word, YES. our rotator cuff area IS the entire upper shoulder area that has all the tendons, ligaments and muscles that actually allow ANY real movement. this also includes the highly mobile acro joint too. without it, our arms would kind just hang there? if you want to be able to actually move your arm in certain ways and have things interconnected, you NEED to have that supra reattached properly again. all they do is sew it back together. but you really DO need to get that very top tendon there reattached, seriously.
that top tendon which is the one i happened to also snap right in half just does the majority of work, so it is the most commonly torn. i can tell you right now, if that very top tendon is NOT actually attatched properly thru damage, the tendon directly underneath THAT particular one WILL also suffer without that needed repair(and it will also effect ligaments and muscle accordingly). my tendon right below the one that was slowly tearing over years but i did not know it(then it finally worked all the way thru and simply out of the blue just snapped completely), actually started to tear too since that one starts to try and compensate for the top one not doing ITS job kinda thing? it simply trys to take on that load which it cannot actually do as far as performing the supras real ROMS so it will start to suffer for it too? so you very easily CAN end up with huge amounts of real ongoing damage(and muscle loss) if things starting right at the very top are not in good shape. it would work its way down all the tendons(and the ligaments and muscles too) eventually? the "domino effect"? thats just how things are within that rotator cuff area. it just works and works and works in 'doing' for us like all day everyday so depending upon what you do, it can simply wear out on us. my supra snapped on me at only age 47? when i had my MRI i was really stunned at the real level of wear and tear types of damage(fraying, bone spurs IN the acro joint too) and all the tears and of course that snapped supra which i did NOT expect at all. my whole shoulder was a mess i did not even know about.
honestly? i would seriously get that one problem area in that supra fixed or IT WILL start impacting other structures as they try and compensate for what is not working properly over time. that will create a much bigger and more in depth type of needed repairs as time goes by and you will simply start to lose more and more ROMS and the abilitys to simply 'do' certain things anymore at all. its just the highly progressive way the damage will go without that very top good "anchor tendon" being attached and holding things together again. believe me, doing this now vs waiting means a much less invasive repair surgery vs what will be even over the next couple years if you wait on this. the recovery would also be much longer, more painful and require much more extensive rehab/PT that just would be needed to get all that damaged/repaired stuff back into sinc again and usable. just because your pain has gone down and become more manageable at this point does NOT mean when other structures start becomming impacted that it wont come back on you or in an even more profound way than it was before as newer and much deeper damage creates new pain?
have you actually had that very needed consult/eval of the arm/shoulder by a good orthosurgeon yet, just to find out what HIS impression actually is about what may be needed here if you chose a surgical repair? just getting that needed opinion does not mean you are suddenly locked into any type of surgery. you just seriously DO need to get the expert opinion and eval on how much real ROM is also being impacted/lost right now too. just getting this done and overwith now will save you alot more damage, hassle, and pain later on, trust me on that one. what is a much simpler repair now will just progress over time and become a much bigger in depth deal for you.
i do hope for your own sake you at least seek out a good ortho opinion from an ortho that actually specializes in shoulders? they all kind of have their own specialtys, so you DO need that type that does shoulders like on a daily basis for the best possible surgical outcome and opinion too. let me know what you find out. good luck with this, FB
