II. Epidemiology
- Most common in boys ages 12 to 15 years old
III. Physiology
- Tibial tuberosity or tubercle is a proximal tibia Ossification Center
- Tibial tuberosity forms the distal insertion or anchor point of the Patellar tendon
IV. Pathophysiology
V. Risk Factors
- Obesity (Body Mass Index >97th percentile for age)
- Low weight (Body Mass Index <5th percentile for age)
VI. Management
- Initial Management
- Knee Immobilizer or long leg splint
- Precautions regarding Compartment Syndrome (see below)
- Definitive Management
VII. Complications
-
Compartment Syndrome (2 to 20% of Tibial Tuberosity Fractures)
- Associated with injury to the anterior recurrent tibial artery (lies lateral to the tibial tuberosity)
- Higher risk with more complex Fractures extending into proximal tibia
