Findings
The radiographs are not particularly contributory but as to show no osseous injury has been sustained. A soft tissue injury has been sustained about the right ischial tuberosity. There is disruption of a tendon but the common origin right hamstring and then semimembranosus as well as conjoined tendons are intact.
Diagnosis: Isolated Adductor Magnus Origin Tear
Injuries of the adductor magnus origin are uncommon and particularly much less frequent than of the proximal hamstring. This case particularly highlights the anatomy about the ischial tuberosity. It is imperative to know that not only the hamstring origin is present about the tuberosity but so is a portion of the adductor magnus (AM). The AM has so called pubofemoral and ischiocondylar origins with the latter being affected in this case. The only case reports that could be found were in high level athletes. This case occurred in an older adult.
In the small case series, even in high level athletes these injuries were treated conservatively as was this patient. This highlights the need to correctly identify the pathology involved as displaced hamstring origin injuries frequently require surgical intervention.
