In medical terms, XOP is an abbreviation that stands for "X-ray Out of Plaster." This phrase specifically refers to a diagnostic imaging procedure where an X-ray is taken after a patient's plaster cast or other immobilization device has been temporarily removed.
Understanding XOP: X-ray Out of Plaster
The term "plaster" in this context typically refers to an orthopedic cast, splint, or other external immobilization device used to stabilize a fractured bone or injured joint. When a healthcare provider orders an "XOP," it indicates that the X-ray images are to be obtained without the cast or splint in place.
Here's a quick breakdown of the abbreviation:

Why is an "X-ray Out of Plaster" Performed?
Performing an X-ray with the cast removed offers several critical advantages and serves various diagnostic purposes:
- Improved Image Clarity: A cast, especially one made of plaster, can create shadows or artifacts on an X-ray image, making it difficult to clearly visualize the underlying bone structure. Removing the cast allows for unobstructed views and higher-quality images, which are essential for accurate diagnosis and monitoring.
- Assessment of Healing Progress: Physicians can get a clearer picture of how a fracture is healing, observe the formation of new bone (callus), and evaluate the alignment of bone fragments more precisely.
- Checking for Complications: It enables the detection of potential issues such as:
- Malunion: When a fracture heals in an incorrect position.
- Nonunion: When a fracture fails to heal.
- Hardware Issues: If internal fixation devices (like pins, plates, or screws) are used, XOP can better assess their position and integrity without interference.
- Pressure Sores or Skin Issues: While not directly visible on X-ray, removing the cast for the XOP procedure also provides an opportunity to inspect the skin underneath for any complications.
- Preparation for Cast Change or Removal: An XOP may be taken before a new cast is applied, or before the final removal of a cast, to confirm that healing is sufficient to proceed with the next stage of treatment or rehabilitation.
The Process of an XOP
The procedure for an XOP typically involves several steps:
- Cast Removal: A trained healthcare professional, often a doctor or an orthopedic technician, carefully removes the existing plaster cast or splint using specialized tools.
- X-ray Imaging: The patient is then positioned for the X-ray, and images are taken of the affected area from various angles.
- Assessment and Decision: The images are reviewed by a radiologist and the treating physician to assess the bone's healing status, alignment, and any potential issues.
- Recasting or Further Action: Based on the X-ray findings, the patient may receive a new cast (which might be lighter or smaller, or adjusted for improved alignment), a different type of immobilization device, or the cast may be completely removed if the bone has healed sufficiently. Sometimes, further intervention like surgery might be planned.
Common Scenarios for XOP
XOPs are frequently ordered in orthopedic practices and emergency departments, particularly for:
- Fracture Management: To monitor the healing process of various types of bone fractures in the arm, leg, wrist, or ankle.
- Post-Surgical Evaluation: After surgery involving bone fixation or reconstruction where a cast was applied.
- Follow-up Appointments: During routine check-ups for patients undergoing prolonged immobilization.
Understanding medical abbreviations like XOP is crucial for effective communication among healthcare professionals and can provide clarity for patients regarding their diagnostic procedures.
