Summary
Observing the scapulohumeral line on shoulder X-rays helps detect posterior glenohumeral joint dislocation. This view also aids in assessing the proximal humerus and scapula relationship for various shoulder conditions.
Area of Science:
- Radiology
- Orthopedics
- Medical Imaging
Background:
- Glenohumeral joint dislocations can be challenging to diagnose.
- Accurate assessment of the scapulohumeral relationship is crucial for shoulder pathology evaluation.
Purpose of the Study:
- To highlight the utility of the scapulohumeral line in shoulder radiography.
- To improve the diagnostic confidence in ruling out posterior shoulder dislocations.
- To demonstrate the value of this radiographic line in evaluating various shoulder pathologies.
Main Methods:
- Review of true anteroposterior radiographic views of the shoulder.
- Focus on the observation of the scapulohumeral line.
- Correlation of the scapulohumeral line with clinical diagnoses.
Main Results:
- Routine observation of the scapulohumeral line increases confidence in excluding posterior glenohumeral joint dislocation.
- The scapulohumeral line facilitates evaluation of the proximal humerus-scapula relationship.
- This assessment is valuable for subacromial space abnormalities, proximal humerus fractures/dislocations, and prosthesis evaluation.
Conclusions:
- The scapulohumeral line is a valuable radiographic marker for shoulder assessment.
- Incorporating scapulohumeral line observation enhances diagnostic accuracy for posterior shoulder dislocations.
- This simple radiographic assessment aids in managing diverse shoulder conditions and post-operative evaluations.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
