Purpose or Case Report:
Ischial tuberosity avulsion fractures, though not uncommon in adolescent athletes, are often overlooked or misdiagnosed. These fractures occur more frequently in males than females. Primary cause of this fracture type is usually a sudden eccentric load on the proximal hamstrings, typically seen during a kicking action in dance, football, or soccer. Due to the limited use of imaging in the evaluation of such injuries, these fractures often are misdiagnosed or underdiagnosed. Recent injuries warrant more conservative management, including rest and relative immobilization. In cases of late diagnosis, delayed healing, or persistent symptomatology, surgical intervention can be undertaken to restore normal anatomy, alleviate symptoms, and facilitate healing. Minimally invasive CT-guided percutaneous needle fenestration has been introduced for symptomatic delayed union ischial tuberosity fractures in adolescents. This percutaneous procedure involves the creation of multiple channels into the bone at the fracture site with an 18 gauge Chiba needle via image guided needle fenestration to enhance blood flow and promote healing of the target area. Following this, a tailored physical therapy program is implemented based on patient symptomatology, individual tissue healing rates, and the current literature related to proximal hamstring injuries. Outcomes to this minimally invasive approach have been promising including cases of complete pain relief, full functional recovery, and a return to sports without limitations.

Outline of Teaching Points:
Ischial tuberosity avulsion fractures are common in adolescent athletes, with a higher incidence in males, caused by sudden eccentric loads on proximal hamstrings during activities like dance, football, or soccer.
Due to limited imaging use, these fractures are often overlooked or misdiagnosed, leading to delayed healing or persistent symptoms.
Recent injuries may benefit from conservative management, involving rest and relative immobilization.
Surgical intervention becomes necessary for late diagnoses, delayed healing, or persistent symptoms to restore normal anatomy and alleviate symptoms.
Minimally invasive CT-guided percutaneous needle fenestration has shown promising outcomes, facilitating healing with complete pain relief and a return to sports without limitations.
