Distal Clavicle Resection www.ashevilleortho.com Distal Clavicle Resection Impingement syndrome and associated rotator cuff tears are commonly encountered shoulder problems. This condition is caused when the rotator cuff tendons rub the underside of the acromion bone. Chronic rubbing can lead to a weakening and even tearing of the rotator cuff. Symptoms include pain, weakness and loss of motion. Whether this procedure is done using a scope or through a small incision is dependent on the severity of the tear and the doctor’s preference.

This condition is caused when the rotator cuff tendons rub the underside of the acromion bone. Chronic rubbing can lead to a weakening and even tearing of the rotator cuff. Symptoms include pain, weakness and loss of motion. Whether this procedure is done using a scope or through a small incision is dependent on the severity of the tear and the doctor’s preference. The method shown in these animations is with a scope. Bursitis and Bone Spurs One of the most common problems causing shoulder pain is known as bursitis. Bursitis consists of chronic inflammation of the gliding tissue (bursa) that protects the rotator cuff tendons from rubbing against the undersurface of the bone. Adding to the problem, a bone spur may develop on the undersurface of the acromion which reduces the space in which the rotator cuff tendons can glide. Incisions Small incisions (portals) are made around the joint. The scope and surgical instruments will go into these incisions. This content is for informational purposes only.

Asheville Orthopaedic Associates • (828) 252-7331 www.ashevilleortho.com Visualization The scope is inserted into the back of the shoulder joint. Saline solution flows through a tube (cannula) and into the bursa sac to expand the joint and to improve visualization. The image is sent to a video monitor where the surgeon can see inside the joint. Bursa Sac and Bone Spur Removal A specialized surgical instrument is used to remove the inflamed and irritated bursa sac. A surgical bur is used to remove bone and bone spurs from the underside of the acromion and clavicle. More space is created for the rotator cuff tendons. Creating Space In the case of an arthritic AC joint some of the bone is removed from the end of the clavicle to create more space. This content is for informational purposes only.

Physical therapy may be recommended by your physician to restore motion and strength to your arm and shoulder. A full recovery may take 2-3 months. This content is for informational purposes only.

ROTATOR CUFF PATHOLOGY The three most common types of rotator cuff pathology are tendinitis, tendinosus, and tearing. Excessive physi- cal stress placed on the rotator cuff tendon can cause ir- ritation and inflammation of the tendon, in other words, tendinitis. If the physical stress is chronic, the inflam- matory process often subsides and degeneration of the fascial tendinous tissue occurs; this is referred to as tendinosus. The degeneration of tendinosus results in weakness of the tendon’s structure, and with continued Teres minor physical stress, whether it is overuse microtrauma or a macrotrauma, a rotator cuff tendon tear might occur.

Investigations showed severe rotator cuff disease. This was treated conservatively with physiotherapy and corticosteroid injection into both joints with good pain relief but no improvement in function. She subsequently presented with increasing posterior thoracic pain with plain films reporting no evidence of rib fracture. Bone scintigraphy showed severe rotator cuff disease and degenerative joint disease at multiple sites. The single photon emission computed tomography (SPECT)/ x-ray Computed Tomography (CT) showed bilateral scapula spine fractures of long standing with a probable non-union on the left side. These fractures are rare and difficult to treat when associated with rotator cuff disease. INTRODUCTION Fractures of the scapula spine are rare, with a reported level of dysfunction remained significant with marked restriction frequency of less than twenty cases in the literature [1-8].

Provencher, M.D., M.C., U.S.N.R. Purpose: To perform a quantitative anatomic evaluation of the (1) coracoid process, specifically the attachment sites of the conjoint tendon, the pectoralis minor, the coracoacromial ligament (CAL), and the coracoclavicular (CC) ligaments in relation to pertinent osseous and soft tissue landmarks; (2) CC ligaments’ attachments on the clavicle; and (3) CAL attachment on the acromion in relation to surgically relevant anatomic landmarks to assist in planning of the Latarjet procedure, acromioclavicular (AC) joint reconstructions, and CAL resection distances avoiding iatrogenic injury to sur- rounding structures. Methods: Ten nonpaired fresh-frozen human cadaveric shoulders (mean age 52 years, range 33- 64 years) were included in this study. A 3-dimensional coordinate measuring device was used to quantify the location of pertinent bony landmarks and soft tissue attachment areas. The ligament and tendon attachment perimeters and center points on the coracoid, clavicle, and acromion were identified and subsequently dissected off the bone. Coordinates of points along the perimeters of attachment sites were used to calculate areas, whereas coordinates of center points were used to determine distances between surgically relevant attachment sites and pertinent bony landmarks.

  • Surface Anatomy and Markings of the Upper Limb Pectoral Region
    INTRODUCTION TO SURFACE ANATOMY OF UPPER & LOWER LIMBS OBJECTIVES By the end of the lecture, students should be able to: •Palpate and feel the bony the important prominences in the upper and the lower limbs. •Palpate and feel the different muscles and muscular groups and tendons. •Perform some movements to see the action of individual muscle or muscular groups in the upper and lower limbs. •Feel the pulsations of most of the arteries of the upper and lower limbs. •Locate the site of most of the superficial veins in the upper and lower limbs Prof. Saeed Abuel 2 Makarem What is Surface Anatomy? • It is a branch of gross anatomy that examines shapes and markings on the surface of the body as they are related to deeper structures. • It is essential in locating and identifying anatomic structures prior to studying internal gross anatomy. • It helps to locate the affected organ / structure / region in disease process. • The clavicle is subcutaneous and can be palpated throughout its length. • Its sternal end projects little above the manubrium. • Between the 2 sternal ends of the 2 clavicles lies the jugular notch (suprasternal notch). • The acromial end of the clavicle can be palpated medial to the lateral border of the acromion, of the scapula. particularly when the shoulder is alternately raised and depressed. • The large vessels and nerves to the upper limb pass posterior to the convexity of the clavicle. 4 • The coracoid process of scapula can be felt deeply below the lateral one third of the clavicle in the Deltopectoral GROOVE or clavipectoral triangle.

Gowd,BSb, Eamon D. Bernardoni,MSb, Brian J. Cole, MD, MBAb, Nikhil N. Verma,MDb,*, Konstantinos Natsis, MD, PhDa aDepartment of Anatomy and Surgical Anatomy, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Thessaloniki, Greece bDivision of Sports Medicine, Department of Orthopaedic Surgery, Rush University Medical Center, Chicago, IL, USA Background: The lateral extension of the acromion from the glenohumeral joint is the critical variable that both the acromial index and critical shoulder angle reflect. The purpose of this study was to establish a simple and reproducible method to directly measure the lateral extension of the acromion that will be independent of patient demographic characteristics, scapular rotation, or other morphologic features of the shoulder. Methods: This study used 128 unpaired cadaveric scapulae with a mean age of 69.4 ± 11.1 years (66 right and 62 left scapulae, 65 female and 63 male cadaveric specimens). The lateral extension of the acromion was measured from the supraglenoid tubercle to the most lateral point of the acromion with a digital caliper placed perpendicular to the scapula long axis. This distance was called the “lateral offset of the acromion.” Results: The lateral offset was 2.62 ± 0.72 cm in men and 2.69 ± 0.73 cm in women. The offset was 2.61 ± 0.66 cm in right and 2.70 ± 0.78 cm in left scapulae.
