Summary
Imaging hamstring injuries requires understanding how their appearance changes over time and with different modalities. Magnetic resonance (MR) imaging is consistently helpful for evaluating muscle, tendon, and bone in hamstring injuries.
Area of Science:
- Radiology
- Sports Medicine
- Musculoskeletal Imaging
Background:
- Hamstring injuries are common in athletes and can present with varied imaging findings.
- Accurate diagnosis is crucial for effective treatment and rehabilitation.
Purpose of the Study:
- To review the imaging features of hamstring injuries.
- To correlate imaging findings with injury timeline and modality used.
Main Methods:
- Review of imaging findings in 22 patients (18 male, 4 female) with clinically diagnosed hamstring injuries.
- Utilized radiography, conventional tomography, computed tomography (CT), and magnetic resonance (MR) imaging.
- Analysis of findings based on time elapsed since injury.
Main Results:
- Early radiographs (<1 week) were normal or showed ischial apophysis avulsion.
- Radiographs and conventional tomography (1 week-3 months) showed confusing changes like callus and osteolysis.
- CT aided in identifying healing avulsion fractures.
- MR imaging proved consistently helpful for evaluating muscle, tendon, and bone, regardless of injury timing.
Conclusions:
- Understanding the temporal evolution of hamstring injury imaging is key.
- Familiarity with diverse imaging modalities enhances diagnostic accuracy.
- MR imaging offers comprehensive evaluation of hamstring injuries.
