Abstract: Rotator cuff of glenohumeral joint is a group of muscles and their tendons which surrounds and protects the wholeness of the glenohumeral joint and functions as a shoulder rotator. Shoulder pain is commonly found and is mostly caused by tendinitis of the rotator cuff or subacromial bursitis. There are four important muscles of this rotator cuff: supraspinatus, infraspinatus, teres minor, and subscapularis (SITS) muscles. Among them, the most troublesome is the tendon of supraspinatus muscle that functions as a sheet as well as the abductor of glenohumeral joint. Therefore, tendinitis of this muscle is associated with spontaneous pain and disturbance in lifting the superior extremity. This cuff structure shows that tendons of the SITS muscles together with the capsule of genohumeral joint and the joint structure itself enable a very wide range of motion with a consequence of being troubled easily.Keywords: glenohumeral, rotator cuf, tendon, jointAbstrak: Manset rotator sendi bahu adalah sekelompok otot dan tendonnya yang mengelilingi dan menjaga keutuhan articulatio genohumerale dengan fungsi lain sebagai rotator brachium. Nyeri bahu sering ditemukan dan umumnya disebabkan oleh tendinitis manset rotator atau bursitis subacromiale. Di antara keempat tendines, yang tersering mengalami gangguan yaitu tendon m. supraspinatus yang selain sebagai pembungkus juga berfungsi sebagai abduktor articulatio glenohumerale sehingga selain nyeri spontan juga ditemukan kesulitan mengangkat membrum superior. Struktur manset ini menunjukkan bahwa tendines keempat otot tersebut bergabung dengan capsula articularis genohumerale dengan struktur sendinya yang memungkinkan pergerakan bahu yang sangat luas tetapi dengan konsekuensi akan lebih mudah terjadi gangguan.Kata kunci: sendi bahu, manset rotator, tendon, articulatio

Background: Extension of the elbow joint is maintained during shoulder flexion. In contrast, the arm starts from the flexed position of the elbow joint and the joint gradually extends during reaching elevation. Objectives: This study aimed to compare the kinematic elements and electromyographic (EMG) activities of the rotator cuff muscles between flexion and reaching elevation. Methods: The study included 10 healthy young men. (average age, 21.5 ± 3.4 years), and measurements were performed on their dominant arms. A three-dimensional motion analyzer was used to record the following elements during shoulder flexion and reaching elevation: the angles of glenohumeral joint elevation and scapular upward rotation, scapulohumeral rhythm, external rotation of the humerus, and glenohumeral plane shifting from the coronal plane. The EMG activities in the supraspinatus, infraspinatus, subscapularis, and teres minor were recorded simultaneously. Results: The plane of reaching elevation was retained at 60° from the coronal plane. The glenohumeral planes (P < 0 .01) and the external rotation angles of the humerus below 90° of elevation (P < 0.05) were significantly different between both the motions. The EMG activities in the supraspinatus (P < .01), infraspinatus (P < 0.05), and teres minor (P < 0.01) were significantly lower while reaching elevation than those during flexion. Conclusion: The motion plane at 60° from the coronal plane, movement of the humeral external rotation, and EMG activities of the rotator cuff muscles were different during reaching elevation and shoulder flexion.

For patients with adhesive capsulitis, hydrodilatation is typically performed using corticosteroids with ultrasound guidance via the posterior glenohumeral recess. Recently, a new intervention technique via the rotator cuff interval has been described. This study aimed to compare the efficacy of hydrodilatation with triamcinolone acetonide via the posterior glenohumeral recess and the rotator cuff interval in patients with adhesive capsulitis. This prospective randomized controlled trial was conducted in a tertiary care center with a follow-up period of 12 weeks. We enrolled 64 patients diagnosed with shoulder adhesive capsulitis. The subjects were randomly assigned to two groups that received hydrodilatation with corticosteroids either through the posterior glenohumeral recess or though the rotator cuff interval. The injection contained 4 ml of triamcinolone acetonide (40 mg) mixed with 4 ml of 2% lidocaine hydrochloride and 12 ml of normal saline. The shoulder pain and disability index, visual analog scale for pain, and range of motion were analyzed before and at 6 and 12 weeks after the treatment. Both groups experienced improvements in the visual analog scale scores, shoulder pain and disability index scores, and range of motion throughout the study period. A significant group-time interaction was observed in terms of the visual analog scale for pain during motion (p = 0.019), favoring hydrodilatation through the rotator cuff interval. Thus, hydrodilatation through the rotator cuff interval might be a better treatment option than that through the posterior glenohumeral recess for patients with adhesive capsulitis, considering its superior effect in alleviating pain during shoulder movement.

The biomechanics of the glenohumeral joint depend on the interaction of both static and dynamic stabilizing structures. The combined effect of these stabilizers is to support the multiple degrees of motion within the glenohumeral joint. Total shoulder arthroplasty requires release of contracted tissues, repair of rotator cuff defects, reconstruction of normal skeletal anatomy with proper sizing, and positioning of components. Arthroplasty of the shoulder is unlike arthroplasty of the hinge joints when the collateral ligaments afford a high degree of stability and is even distinct from the hip when bony conformity is large and range of motion is less. The goal of this paper is biomechanical analyses of normal, injured and implanted shoulder joint.

The glenohumeral joint architecture allows for a very ample range of motion. This same architecture, so beneficial for shoulder mobility, also makes the glenohumeral joint particularly prone to instability. Damage to the glenoid labrum is present in many patients with shoulder instability, although the complexity of the pathology involved in shoulder instability goes beyond labral tears. The rotator cuff and the biceps tendon, discussed in chapter 6, The Rotator Cuff and Biceps Tendon, are intimately involved with instability and the labrum; some of the concepts described in chapter 6 will apply here as well. This chapter covers shoulder instability and the labrum, including management of the acute glenohumeral joint dislocation, recurrent posterior instability and posterior labral tears, multidirectional instability, superior labral tears, failed instability surgery, and salvage procedures.

SummaryThe aim was to determine the relative contribution of the glenohumeral ligaments/joint capsule complex and the limited joint volume/adhesion-cohesion (LJV/AC) mechanisms to the static stability of the canine glenohumeral joint (GHJ). The GHJ of 32 complete cadaver specimens were manipulated to determine the presence of gross laxity (>2mm translation) at joint angles of 150°, 135° and 90°. Following the removal of the peri-articular muscles, laxity was measured by applying a 15N force to the scapula in a variety of directions whilst the humerus was fixed to a jig. This was repeated for the abovementioned angles in intact joints and after venting and flushing to eliminate the LJV/AC mechanisms. Results of clinical palpation and biomechanical studies were compared. Manipulation revealed a marked variation between joints although there was a tendency for progressive laxity as the joint was flexed. This finding was supported by the biomechanical study that also demonstrated no significant difference between intact and vented joints except in a cranio-caudal direction at 135° and 90°, and in a medial/lateral direction at 135°. Static stabilisers permitted a wide range of motion. Individual clinical palpations did not correlate well with biomechanical findings. Manipulation was difficult to perform and is unlikely to be a reliable method for determining subtle joint laxity. The static stabilisers do not appear to play a significant role in providing joint constraint during normal range of motion (except extension). Diagnoses of pathological laxity attributable to the static stabilisers should be made with caution and surgical treatments should take cognizance of the above-mentioned biomechanical features.

Abstract Purpose The teres minor is particularly important for activities that require external rotation in abduction in the settings of both rotator cuff tears and reverse shoulder arthroplasty. This study sought to assess the incidence of teres minor fatty infiltration in a large cohort of consecutive patients evaluated with shoulder MRI for shoulder pain and to identify all associated pathologies in an effort to determine the various potential etiologies of teres minor involvement. Methods A retrospective review of 7,376 non-contrast shoulder MRI studies performed between 2010 and 2015 were specifically evaluated for teres minor fatty infiltration. Studies were reviewed by two fellowship trained musculoskeletal radiologists. Muscle atrophy was graded on a 3-point scale according to Fuchs and Gerber. The remaining rotator cuff tendons and muscles, biceps tendon, labrum, and joint surfaces were assessed on MRI as well. Results In this series, 209 (2.8%) shoulders were noted to have fatty infiltration of the teres minor. The rate of isolated fatty infiltration of the teres minor was 0.4%. Concomitant deltoid muscle atrophy was common, and occurred in 68% of the shoulders with fatty infiltration of the teres minor. Tearing of the teres minor tendon was extremely rare. Conclusion Fatty infiltration of the teres minor can occur in isolation, be associated with deltoid muscle atrophy only, or occur in the setting of rotator cuff full tears. Thus, fatty infiltration of the teres minor may be related to a neurologic process or disuse. Further long term longitudinal studies are necessary to be elucidate the etiologies. Level of Evidence Level IV.

Kegiatan dasar berupa gerak merupakan suatu kebutuhan dan tuntutan manusia terutama dalam era globalisasi seperti sekarang. Anggota gerak atas memiliki keterlibatan yang sangat tinggi dalam semua aktivitas yang dilakukan oleh manusia. Seluruh aktivitas yang dilakukan sehari-hari banyak bergantung terutama pada fungsi anggota gerak atas. Tangan dan lengan merupakan pemeran utama, sehingga apabila terjadi gangguan tertentu, hal tersebut akan mengganggu mobilitas dan kegiatan manusia. Sendi bahu merupakan salah satu sendi besar yang paling umum terjadi dislokasi, hal tersebut dapat terjadi karena rentang gerak sendi yang luas, dangkalnya fossa glenoid, dan ligament laxity pada beberapa orang. Dislokasi sendi bahu merupakan suatu kondisi dimana terjadi pergeseran caput humerus dari sendi glenohumeral, sehingga hal tersebut dapat menyebabkan kerusakan pada saraf serta dapat terjadi berulang. Jurnal ini bertujuan untuk menjelaskan efektivitas pemberian intervensi terapi latihan dan terapi infrared pada kasus dislokasi sendi bahu dan menambah pengetahuan pembaca mengenai kasus dislokasi sendi bahu. Metode penelitian yang digunakan yaitu deskriptif kualitatif dengan pengambilan materi berbasis literature review. Hasil penelitian menunjukkan bahwa pemberian terapi latihan dan terapi infrared efektif untuk menurunkan nyeri, meningkatkan kekuatan otot, meningkatkan lingkup gerak sendi (LGS), serta meningkatkan kemampuan fungsional pasien yang menderita kasus dislokasi sendi. Basic activities are in the form of a necessity and human need, especially in the era of globalization as it is now. Upper limbs have a very high involvement in all activities carried out by humans. Everything that is done daily, especially activities on the function of the upper limbs. Hands and arms are the main actors, so that if certain disturbances occur, it will interfere with mobility and human activities. The shoulder joint is one of the most commonly dislocated large joints, this can occur due to the wide range of motion of the joint, the shallowness of the glenoid fossa, and ligament laxity in some people. Dislocation of the shoulder joint is a condition in which the humeral head shifts from the glenohumeral joint, so that it can cause nerve damage and can occur repeatedly. This journal aims to explain the effectiveness of providing exercise therapy and infrared therapy in shoulder dislocation cases and the reader's knowledge about shoulder dislocation cases. The research method used is descriptive qualitative by taking material based on a literature review. The results showed that providing exercise therapy and infrared therapy to reduce pain, increase muscle strength, increase range of motion, and improve the ability of patients suffering from joint dislocation cases.

Background The objective of the present study was to determine the size and position of the rotator cuff moment arms constructed from the cuff footprints, incident on the line of force acting through the humeral head. Methods Five humeri were dissected, leaving the footprints of the rotator cuff intact. Each of the rotator cuff footprints and the cartilage/calcar interface were digitized and the articular surface was scanned using a high precision surface laser scanner. All of the data were merged into the same coordinate system. The centroid of each cuff footprint, centroid of the articular surface of the humerus (G) and the centroid of the articular surface of the glenoid (P) were calculated. Moment arms were measured as the intersection of a perpendicular line of force from each footprint centroid onto the resultant line of force to the centroid of the Glenoid (P). Results The mean moment arms of the supraspinatus, infraspinatus and subscapularis muscles were incident close to the centroid (G), whereas teres minor was lateral to the centroid, consistently. Conclusions The teres minor moment arm aligned distal to the centroid of the sphere, consistently. The results may provide an understanding of the function of each muscle as a mobilizer or stabilizer of the glenohumeral joint. Further investigation is necessary.
