COMPARISON OF THE RESULTS OF GLENOHUMERAL JOINT RADIOGRAPH IMAGES DESCRIPTION ON AP OBLIQUE WITH 15 ⁰ , 25 ⁰ , 30 ⁰ AND HORIZONTAL ANGULAR BEAM

Glenohumeral joint is the broadest joint in our body. Glenohumeral joints bullet includes joint with very shallow bowls. The examination technique to see the glenohumeral joint is with the AP position, RPO and LPO formed the Oblique patient position with 15 ⁰ , 25 ⁰ , 30 ⁰ and horizontal angular beam. This comparison research is to know the results of Glenohumeral Joint Radiograph Oblique images on AP with of 15 ⁰ , 25 ⁰ , 30 ⁰ and angular horizontal beam at the Radiology Installation of Ulin Banjarmasin Hospital. This research is a descriptive quantitative design. Data were collected by observation and by analysing results of questionnaires that were distributed to 20 respondents to see the results of comparison Glenohumeral Joint Radiograph on AP Oblique images with of 15 ⁰ , 25 ⁰ , 30 ⁰ and angular horizontal beam at the Radiology Installation of Ulin Banjarmasin Hospital. Using a horizontal beam angular direction is better because the joint gap between the head of the humerus and the glenoid fossa is completely open and there is a very clear image of the glenoid fossa. There are differences in the Glenohumeral Joint on AP Oblique radiographs with 15 ⁰ , 25 ⁰ , 30 ⁰ and horizontal angular beam. The examination with the position AP AP Oblique Oblique position using the horizontal direction ray shows an image of the glenohumeral joint for a more informative result.


Introduction
Professional technologist must know, understand and master the basics of correct radiographic techniques. The basic techniques of radiographic question are about position of the patients and the objects, as well as the projected image during the examination. One of the examples is the examination of shoulder joint. A shoulder joint is a complex joint made up of several joints which are glenohumeral joint, acromioclavicular joint, sternoclavicularis joint, and scapulothoracalis joint with the movement of interdependence with one another (Wibowo, 2009).
Glenohumeral joint is the most comprehensive motion joint in our body.
Glenohumeral joint includes bullet joints and joints with a very shallow bowl. Glenohumeral joints are formed by the humeral head round and glenoidalisscapula shallow cavity and pear-shaped. Joint surface is covered with hyaline cartilage, and glenoid cavity is deepened by the labrum glenoidale (Snell, 1997). This joint has three degrees of freedom which enable them to move in three planes of motion (Suhastika, 2015). Movements which can be done by the glenohumeral joint are flexion, extension, abduction, eksorotasi, endorotasi, and circumduction (Snell, 2000).
One problem that can occur in the joints is that a Glenohumeral Joint can lose active and passive mobility. It is Insidious (unintelligible occurrences) and progressive as a result of the joint capsule contracture. The prevalence of this disease is approximately 2% of the general population and 10-29% of diabetics in the United States (Kurniasih, 2011), and the American Academy of Orthopedic Surgeons describes prevalence shoulder pain reaches 50% of the general population. Research from Luine, et al in Kennedy, et al (2006) shows the increase of the number of people's experiencing shoulder joint complaint by an average of 6.9% to 26%, which increased every 1 month on average by 18.6% up to 31 %, rising 4.7% to 46.7% annually, and the average increase for several years by 6.7% to 66.7%. Global trade association mentioned the shoulder injury each day (Setiyawati et al, 2013).
According to Ballinger (1995), examination of the shoulder joint to see the image of the glenohumeral joint is composed of examination techniques to position the AP with the patient's shoulder attached to the cassette with the patient back to the bucky stand, position RPO with the patient's shoulder attached to the cassette, but the shoulders of patients left skewed fore thus forming Oblique patient positioning, and LPO with tape attached to the patient's shoulder, but the right of the patient's shoulder skewed forward, forming a patient positioning Oblique direction on 15⁰, 25⁰, 30⁰ and horizontally beam.
Based on the description above, it is necessary to furtherly analyze regarding the comparison of the results of the Glenohumeral Joint Radiographs photo illustration AP Oblique direction on 15⁰, 25⁰, 30⁰ and horizontally beam at the Radiology Installation of Ulin Banjarmasin Hospital.

Method
This research is descriptive quantitative, conducted in May 2018. The collection of data was done by observing, conducting direct examination process Glenohumeral Joint using variation on 15⁰, 25⁰, 30⁰ and horizontal cranially at the position AP Oblique, and analyzing the results of questionnaires distributed to 20 respondents to compare the results of the Glenohumeral Joint Radiographs photo illustration AP Oblique direction on 15⁰, 25⁰, 30⁰ and horizontal beam at the Radiology Installation of Ulin Banjarmasin Hospital.

Conclusion and Suggestion
There are differences in the results of radiographs glenohumeral joint AP Oblique direction on 15⁰, 25⁰, 30⁰ and horizontal beam. Radiographers should perform the examination with the position AP Oblique position using the horizontal direction ray because it shows a more informative image of the glenohumeral joint.
