Radiographic evaluation is an essential tool in diagnosing fractures of the hand and wrist. Standard projections used in the evaluation of hand and wrist fractures include:
1. PA (Posteroanterior) view: This view is taken with the patient's hand placed flat on the imaging surface, palm down. It helps to visualize the alignment of the metacarpals, phalanges, and carpal bones. It is useful in detecting fractures, dislocations, and joint abnormalities.
2. Lateral view: This view is taken with the patient's hand placed on its side, with the thumb side facing up. It helps to visualize the alignment of the metacarpals, phalanges, and carpal bones from a different angle. It is useful in detecting fractures, dislocations, and joint abnormalities that may not be visible on the PA view.
3. Oblique view: This view is taken at an angle between the PA and lateral views. It helps to visualize specific structures that may be obscured on the PA or lateral views. It is useful in detecting fractures, dislocations, and joint abnormalities that may be missed on the other views.
The significance of each view in the diagnosis of hand and wrist fractures is as follows:
- PA view: This view helps to assess the alignment of the bones in the hand and wrist, as well as detect fractures, dislocations, and joint abnormalities. It is particularly useful in evaluating fractures of the metacarpals and phalanges.
- Lateral view: This view provides a different perspective of the bones in the hand and wrist, allowing for the detection of fractures, dislocations, and joint abnormalities that may not be visible on the PA view. It is particularly useful in evaluating fractures of the carpal bones and distal radius.
- Oblique view: This view helps to visualize specific structures that may be obscured on the PA or lateral views, such as the scaphoid bone. It is particularly useful in detecting fractures, dislocations, and joint abnormalities that may be missed on the other views.
In conclusion, the radiographic evaluation of hand and wrist fractures involves the use of standard projections such as PA, lateral, and oblique views. Each view plays a significant role in the diagnosis of fractures, dislocations, and joint abnormalities in the hand and wrist, allowing for accurate assessment and appropriate treatment.

Radiographic Evaluation of Fractures of the Hand and Wrist
Radiographic evaluation plays a crucial role in diagnosing and assessing fractures of the hand and wrist. The following standard projections are commonly employed:
1. Posterioanterior (PA) View:
- Provides a frontal view of the hand and wrist.
- Visualizes the distal radius, ulna, carpal bones, metacarpals, and phalanges.
- Used to assess cortical integrity, displacement, and angulation of fractures.
2. Lateral View:
- Provides a sagittal view of the hand and wrist.
- Visualizes the dorsal and palmar aspects of the wrist and carpal bones.
- Helps evaluate the height of any fracture fragments, dorsal/palmar angulation, and comminution.
3. Oblique Views:
- Include the following:
- Ulnar oblique view: Provides a semi-axial view of the scaphoid bone, assessing for fractures and dislocations.
- Radial oblique view: Visualizes the triquetral and lunate bones, aiding in diagnosing fractures and subluxations.
- Helpful in confirming subtle fractures or evaluating displaced fragments.
4. Scaphoid View:
- A specialized view used to assess the scaphoid bone.
- Obtained with the wrist in ulnar deviation and the thumb pressed against the radial ridge.
- Provides a tangential view of the scaphoid, allowing for better detection of occult fractures.
Significance of Each View:
- PA view: Provides an overall assessment of the hand and wrist, including the distal radius, ulna, carpal bones, metacarpals, and phalanges.
- Lateral view: Evaluates dorsal and palmar displacement, angulation, and comminution of fractures.
- Oblique views: Confirm subtle fractures or assess displaced fragments in specific carpal bones.
- Scaphoid view: Specifically used to diagnose and assess scaphoid fractures, which can be difficult to detect on other views.
These standard projections provide comprehensive visualization of the hand and wrist, enabling accurate diagnosis and evaluation of fractures. Proper execution and interpretation of these views are essential for appropriate management and treatment planning.
