    After satisfactory level of general anesthesia was reached and patient was in the supine position, he was further placed in a beach chair position. A longitudinal incision was created over the region of the left AC joint. At this time, sharp dissection was conducted down to the fascial plane. The fascial plane was then further incised, reflecting both the deltoid and the trapezial fascia and the distal aspect of the clavicle undermining the clavicle; at this time we simply proceeded excising the distal 1 cm of the clavicle with use of a reciprocal saw. With completion of this element of the procedure, the margins of the bone were otherwise unremarkable in gross appearance. It was also significant to note at this time the acromial end of the articulation was unremarkable. The wound was irrigated, followed by controlling of punctate bleeding with use of electrocautery, followed by the closure of the deltotrapezial fascia. At this time I further imbricated sutures for stable repair, followed by repair of subcutaneous and dermal planes. A simple dressing was applied. The patient tolerated the procedure well and was transported to the recovery room in a stable manner.…

    Scapular dyskinesia is close to me due to its relation with my family. My brother has scapular dyskinesis due to his athletic endeavors in swimming and possibly due to some genetic factors that run in our family. This abnormal scapulohumeral rhythm is seen in shoulder instability, at a rate of 67%, and in shoulder impingement, at a rate of 100%. Shoulder injuries tend to be prevalent at a high rate in today’s population due to impact sports, accidents, and ever increasing elderly population. Although seen very frequently in shoulder instability and impingement, there are no statistics on the incidence of this condition as a whole.…

    To go in-depth, UCL Reconstruction or Tommy John Surgery is where a surgeon uses a tendon graft to replace the UCL, which is located is on the inside of the persons elbow. The tendon graft is used to replace the damaged or tore tendon in the elbow, usually coming from another part of the body where it is not necessary for movement. The graft is then positioned to where it is drilled through the Ulna and Humerus. The most common graft that is used is called the Palmaris graft, in which they remove the tendon located in the wrist. Even though this is the most commonly used, many people are born without this tendon. Other graft options include use of a hamstring, toe extensor, or donor tendon (allograft). When the graft is put all the way through the Ulna and Humerus, it is finally attached to the…
