What occurs during a Grade 3 strain?

During a Grade 3 strain, a complete rupture of the muscle occurs. This type of strain is characterized by a total disruption of muscle fibers, which can severely compromise the muscle’s ability to function properly. Patients typically experience immediate pain, swelling, and an inability to use the affected muscle effectively, as well as potential bruising. The severity of a Grade 3 strain necessitates medical intervention and often requires a significant amount of time for rehabilitation, post-injury. Recognizing the complete rupture is crucial for proper treatment planning and recovery assessment, distinguishing this grade from less severe strains that may involve only partial tears or overstretching.
