Elbow AP
4
Feb

Overview

The AP elbow radiograph evaluates the distal humerus proximal radius and ulna. The patient extends the elbow with the palm up to obtain a true AP projection. This view is essential for detecting fractures and joint effusion.

Technique

Center the detector to the elbow joint and ensure the humeral epicondyles are parallel to the detector. Use appropriate exposure and immobilize the limb to reduce motion. Include the distal humerus and proximal forearm in the field.

Clinical Indications

AP elbow is indicated for trauma pain and limited range of motion. It helps detect supracondylar fractures radial head injuries and joint effusions. Additional lateral and oblique views complement the AP projection.

Image Assessment

Assess cortical continuity and joint alignment and look for fat pad signs indicating occult fracture. Evaluate the radial head neck and coronoid process for injury. Correlate with clinical findings and consider CT for complex fractures.

Pelvis AP
4
Feb

Overview

The AP pelvis radiograph evaluates the pelvic ring hips and proximal femora for fractures and degenerative disease. The patient lies supine or stands with legs internally rotated to profile the femoral necks. This view is a cornerstone for trauma and orthopedic assessment.

Technique

Center the detector to the mid pelvis and ensure equal leg rotation to reduce foreshortening. Use appropriate exposure to penetrate the pelvis and include the iliac crests to proximal femora. Immobilize the patient when trauma is suspected.

Clinical Indications

AP pelvis is indicated for trauma hip pain and preoperative planning. It assesses pelvic ring stability and hip joint space. Additional inlet outlet and Judet views may be required for complex pelvic fractures.

Image Assessment

Evaluate pelvic symmetry sacroiliac joints and hip joint spaces. Inspect for cortical disruption and displacement of the pelvic ring. Document fracture patterns and recommend CT for detailed surgical planning.

Hip AP
4
Feb

Overview

The AP hip radiograph focuses on the proximal femur and acetabulum to assess fractures and degenerative change. The patient lies supine with the leg internally rotated to profile the femoral neck. This view is essential for hip pain and preoperative planning.

Technique

Center the detector to the hip joint and internally rotate the leg approximately 15 degrees. Include the acetabulum and proximal femur in the field and use appropriate exposure. Immobilize the limb to reduce motion artifact.

Clinical Indications

AP hip is indicated for trauma suspected fracture and osteoarthritis assessment. It helps detect femoral neck fractures and joint space narrowing. Additional lateral or cross table views may be required for occult injuries.

Image Assessment

Assess cortical continuity femoral head sphericity and joint space. Look for subcapital fractures and osteophyte formation. Report findings relevant to orthopedic management and surgical planning.

Scapula AP and Lateral
4
Feb

Overview

AP and lateral scapula views evaluate the scapular body spine and glenoid for fractures and deformity. The AP view images the scapula en face while the lateral view profiles the scapular body. These projections are used in trauma and shoulder pathology assessment.

Technique

For AP scapula position the arm across the chest and center the detector to the scapula. For lateral scapula rotate the patient to project the scapula laterally with the arm raised. Use appropriate exposure and immobilize the patient.

Clinical Indications

Scapula views are indicated for trauma with shoulder girdle injury and persistent localized pain. They detect scapular body fractures and glenoid rim involvement. CT is used for complex fractures and surgical planning.

Image Assessment

Assess scapular body contour spine acromion and glenoid rim for cortical disruption. Evaluate for associated rib or clavicle injuries. Report findings relevant to orthopedic referral.

Forearm AP and Lateral
4
Feb

Overview

AP and lateral forearm radiographs evaluate the entire radius and ulna including wrist and elbow joints. These views are essential for detecting shaft fractures and assessing alignment. Proper positioning ensures both joints are included for comprehensive assessment.

Technique

Obtain AP view with the palm up and the forearm flat on the detector. For lateral view flex the elbow 90 degrees and superimpose the radius and ulna. Use appropriate exposure and immobilize the limb to reduce motion.

Clinical Indications

Forearm series are indicated for trauma pain and suspected shaft fractures or dislocations. They assess for malrotation and joint involvement. CT is used for complex fractures and preoperative planning.
