Case in brief
Three patients presented with sports-related injuries characterized by sacrotuberous ligament damage while having normal hamstring tendons. MRI findings included thickening and irregularities of the ligament, along with edema in the adjacent gluteus maximus muscle. Notably, there was no bone edema. All patients experienced improvement with conservative management, including rest and nonsteroidal anti-inflammatory medications.
Diagnostic / clinical pearl
MRI can effectively identify sacrotuberous ligament injuries, even in the absence of hamstring tendon abnormalities, which may aid in accurate diagnosis.
