Hip Frog Leg Lateral
4
Feb

Overview

The frog leg lateral hip view positions the hip in flexion abduction and external rotation to profile the femoral head and neck. It is useful for detecting slipped capital femoral epiphysis and femoral neck fractures. This projection complements the AP hip for comprehensive assessment.

Technique

Flex the hip and knee and abduct the thigh with the sole of the foot against the opposite leg. Center the detector to the hip and use appropriate exposure for the proximal femur. Ensure patient comfort and avoid excessive rotation.

Clinical Indications

Frog leg lateral is indicated for pediatric hip disorders trauma and suspected femoral neck pathology. It provides a lateral perspective of the femoral head neck and greater trochanter. Alternative lateral techniques are used when positioning is limited.

Image Assessment

Evaluate the relationship of the femoral head to the neck and look for epiphyseal displacement. Assess cortical integrity and joint congruity. Document findings and recommend orthopedic referral when indicated.

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.

Clavicle AP Axial
