Buckle (Torus) Fracture of Pediatric Female Left Distal Radius

This module allows traditional bone setters, pre-hospital providers, clinical officers, nurses, nurse practitioners, and medical officers to become confident and competent in performing point-of-care ultrasound diagnostic imaging to rule out the presence of a pediatric distal forearm fracture and distinguish between buckle (torus) fractures and cortical break fractures to make appropriate referrals as part of the management of closed pediatric (< 16 years of age) distal forearm fractures in regions without access to X-ray imaging and orthopedic specialist coverage.[1][2][3][4][5][6][7][8][9]

Self-Assessment Framework[edit | edit source]

Please print off this self-assessment framework before the simulation skills training, review it after the simulation skills training, and file and save a back-up copy of the completed and signed self-assessment framework and your ultrasound images for your training records.

Review all the acquired images to determine if they meet all the quality standards outlined in the checklist below.

Quality Assurance Checklist Standards for Ultrasound Image Acquisition and Interpretation
# Proper Technique for Image Acquisition and Interpretation Ultrasound Image Meets Standard Ultrasound Image Does Not Meet Standard
1
Probe (black) is properly oriented with the probe marker (blue) facing distally.
When the probe is properly oriented with the probe marker facing distally, the epiphysis (E), physis (P), metaphysis (M), and diaphysis (D) are oriented in a left-to-right direction.
Ultrasound scan of buckle fracture of forearm (shown by arrow). When the probe is not properly oriented (i.e., the probe marker is facing proximally), the epiphysis (E), physis (P), metaphysis (M), and diaphysis (D) are oriented in a right-to-left direction.
2
Probe is properly positioned perpendicular to the bone.
When the probe is properly positioned perpendicular to the bone, the image is clear with distinct margins of the bone cortex including the epiphysis (E), metaphysis (M), and diaphysis (D).
When the probe is not properly positioned perpendicular to the bone, the image is unclear or without distinct margins of the bone cortex.
3
Probe is properly aligned with the bone
When the probe is properly aligned to the bone, the full length of the epiphysis, metaphysis or diaphysis will be in view in the image.
Lateral view of buckle fracture of radius (shown by arrow). When the probe is not properly aligned to the bone (i.e., is rotated) the epiphysis (E*) will not be fully in view.
4 Probe is set to the proper depth of 4 cm when evaluating the pronator quadratus muscle.
When the probe is set to the proper depth of 4 cm, the entire pronator quadratus muscle is visualized to identify a hematoma.
When the probe is not set to the proper depth of 4 cm, the entire pronator quadratus muscle is not visualized.
5 All features are properly labelled.
In this lateral radius view of a 12-year-old healthy male patient, the epiphysis (E), physis (P), metaphysis (M), and diaphysis (D) are properly labelled.
In this dorsal radius view of a 12-year-old healthy male patient, the diaphysis (D), epiphysis (E), and metaphysis (M) are labelled incorrectly. Click here to also see an image with no labelled features.

Any image that does not meet the standard for all the quality assurance checklist items must be re-acquired in accordance with the techniques described below.
