Computed tomography (CT) is recommended as the initial imaging test for suspected occult hip fractures not visible on X-ray. Magnetic resonance imaging (MRI) should be used if suspicion persists after a negative CT scan.
Area of Science:
- Radiology
- Orthopedic Surgery
- Emergency Medicine
Background:
- Occult hip fractures are challenging to diagnose with standard X-rays.
- Early and accurate diagnosis is crucial for patient outcomes and preventing complications.
Purpose of the Study:
- To compare the efficacy of Computed Tomography (CT) versus Magnetic Resonance Imaging (MRI) in detecting occult hip fractures.
- To provide a clinical guideline for imaging selection in suspected occult hip fractures.
Main Methods:
- A short-cut review of relevant literature was performed.
- Six studies directly comparing CT and MRI for occult hip fractures were analyzed.
- Data on patient groups, study types, outcomes, and weaknesses were tabulated.
Main Results:
- CT is a validated first-line investigation for suspected occult hip fractures.
- MRI is recommended when clinical suspicion for a fracture remains high despite a negative CT scan.
Conclusions:
- CT imaging offers a reliable initial approach for diagnosing occult hip fractures.
- MRI serves as a crucial secondary imaging modality when CT is inconclusive but clinical suspicion is high.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
