The LCL, also known as the radial collateral ligament, connects the humerus (upper arm bone) to the radius (forearm bone) and prevents the elbow from bending outward. When stretched or torn due to falls or trauma, it causes pain and instability. Severe cases may lead to posterolateral rotatory instability (PLRI), where the elbow feels like it’s slipping.
The LCL is crucial for stable, controlled elbow movement — especially during pushing or lifting.
Accurate diagnosis helps guide treatment and prevent long-term instability.
Treatment depends on the severity of the injury and the level of instability.
Rehabilitation is key to restoring elbow strength and range of motion.
Elbow LCL injuries can cause pain and instability that limit daily activity. With specialized care from Dr. Arun Kumar in Madipakkam, you can regain movement, confidence, and long-term joint health. Learn more about our Elbow MCL Injury
