Summary
Magnetic resonance (MR) imaging can predict hamstring injury recovery time in athletes. Specific findings like complete tears and extensive muscle involvement indicate longer convalescence intervals (CI).
Area of Science:
- Sports Medicine
- Radiology
- Musculoskeletal Imaging
Background:
- Hamstring injuries are common in athletes, impacting performance and recovery.
- Accurate prognosis of recovery time (convalescence interval or CI) is crucial for return-to-play decisions.
Purpose of the Study:
- To correlate magnetic resonance (MR) imaging findings in hamstring injuries with short-term prognosis and CI.
- To identify imaging predictors of recovery duration in professional athletes.
Main Methods:
- Retrospective analysis of 14 professional athletes with hamstring injuries.
- Categorization of injuries based on muscle group, affected cross-sectional area, location, and signal intensity on T1- and T2-weighted MR images.
Main Results:
- Longer CIs (> 6 weeks) associated with complete transection, >50% muscle involvement, ganglion-like fluid, hemorrhage, distal myotendinous tears, and deep tears.
- Shorter CIs (< 5 weeks) linked to superficial injuries and small muscle belly tears.
Conclusions:
- MR imaging, combined with identification of poor prognostic factors, can predict CI in athletes with complete hamstring injuries.
- This aids in managing expectations and planning rehabilitation for high-performance athletes.
