Introduction:

Tibial plateau fractures include a multitude of intraarticular fractures that can be associated with a variety of injuries such as comminution, ligament or meniscal injury, and articular depression (1). They are often associated with motor vehicle accidents or falls. Tibial plateau fractures occur in 10.3 per 100,000 people annually (2). Men younger than 50 had a higher incidence compared to women, with the highest age frequency being between 40 and 60 in both men and women (2). The most common type of tibial plateau fracture is a split-depression unicondylar fracture (AO classification type 41B3) which can be lateral, medial or involving the tibial spines and one of the plateaus. The Schatzker classification system is used for prognosis, management, and pre-operative planning (3), although, some patterns of injury may not fit into this system (4). Other systems include the Luo, Hohl, and AO classifications.

Discussion:

CT and radiographs are essential imaging modalities to assess tibial plateau fractures (5, 7). Radiographs are useful in detection but may underestimate the fractures in as many as 43% of cases, whereas CT allows a more accurate depiction and enables more precise surgical planning (6). Since this is an intra-articular fracture, plain radiographs may show lipohemarthrosis (Fig. 2) in the joint space, even with subtle fractures (8). It is important to differentiate lipohemarthrosis with simple hemearthrosis which can also occur with tibial plateau fractures (10). MR imaging is useful to depict the internal anatomy of the knee as well as evaluating meniscal and ligamentous injuries associated with the fractures (1). While CT and MR may determine articular depression equally well, MR can demonstrate greater amounts of comminution than CT (1) and is more suitable for diagnosing cartilage lesions (3).

Treatment:

Using the Schatzker classification, tibial plateau fractures may be managed non-operatively if they are nondisplaced (type I), while multiple indications exist for internal fixation including, but not limited to, open fractures, compartment syndrome, and an articular step off of more than 3 mm (8,9). ​

Neal Joshi is a medical student and aspiring diagnostic radiologist at Rowan University School of Osteopathic Medicine in New Jersey. Prior to medical school, he did research with mouse models for Parkinson’s disease and L-DOPA induced dyskinesias. He also did an internship at Kessler Institute for Rehabilitation in a stroke lab analyzing MR images in ischemic stroke patients with hemispatial neglect. During his time at Rowan, he did research with animal models for traumatic brain injury with an emphasis on electrophysiology of neurons. He graduated from William Paterson University where he completed his studies in biology and biopsychology. Apart from medical school, Neal loves to read, skateboard, go on hikes, and spend time with his friends.


Update July 2022: Dr. Joshi is a Radiology Resident at Thomas Jefferson University in Philadelphia.
