title: [Avulsion of the Proximal Hamstring Insertion. Case Reports].
abstract: Proximal hamstring avulsion is an uncommon muscle injury with a lack of consensus on indications and the timing and technique of surgery. Poor clinical symptoms and difficulties in the diagnostic process can lead to a false diagnosis. The authors present three cases of proximal hamstring avulsion, two complete and one partial ruptures of the biceps femoris muscle. MRI and ultrasound scans were used for optimal treatment alignment. Acute surgery reconstruction (< 4 weeks) was done in two patients. Re-attachment of the full thickness ruptures was performed to the original place and secured by suture anchors, the partial rupture was fixed by a simple suture. Two patients were free of any symptoms at 6 months after surgery, the last one had pain in the subgluteal area and a mild deficit in hamstring strength. Two interesting systematic reviews published on the treatment of proximal hamstring avulsion are discussed in the final part of the paper. Key words: hamstring, rupture, avulsion.
