Background:
Tibial plateau fractures are serious injuries affecting knee function and mobility. While typically associated with high-energy trauma, these fractures are increasingly observed in low-energy mechanisms, particularly among patients with compromised bone health.
Objective:
To investigate the relationship between tibial plateau fractures and bone health parameters, specifically focusing on vitamin D status and bone mineral density, and to determine if fracture classification correlates with metabolic bone disease indicators.
Methods:
A prospective observational study was conducted over 11 months at Evangelismos General Hospital in Athens, Greece. A total of 45 patients with tibial plateau fractures and 28 control patients with knee contusions were assessed. All participants underwent biochemical testing and dual-energy X-ray absorptiometry (DEXA) scanning. Fractures were divided using the Schatzker classification.
Results:
A total of 34 (75.6%) patients with tibial plateau fractures had vitamin D deficiency, and 14 (31.1%) were diagnosed with osteopenia. Osteopenia was significantly more prevalent in low-energy trauma patients (six among nine patients vs. eight among 36 patients in high-energy trauma; 66.7% vs. 22.2%, p = 0.017). However, no statistically significant correlation was found between fracture severity and metabolic markers.
Conclusion:
A substantial proportion of patients with tibial plateau fractures exhibit suboptimal bone health, especially vitamin D deficiency and osteopenia. Routine metabolic screening is recommended, particularly for fractures caused by low-energy mechanisms.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
