What is the Pseudo-Volkmann’s contracture? Pseudo-Volkman contraction, also known as “Pseudo-Volkman syndrome” or “Pseudo-Volkman ischemic contracture,” is a rare and serious medical condition characterized by the development of muscle contractures in response to prolonged or severe ischemia (lack of blood flow) to a specific area of the body. The term “pseudo” is used to differentiate…
Posterior Cruciate Ligament (PCL) Anatomy The PCL, or posterior cruciate ligament, is another important ligament in the knee joint that helps stabilize the knee and prevent backward movement of the tibia in relation to the femur. Like the ACL, an injury to the PCL can cause pain, swelling, instability, and difficulty walking or bearing weight…
What’s the Difference Between Abduction and Adduction? Abduction and adduction are two terms used to describe movements in the body, particularly in relation to the limbs. They are often used in anatomical and medical contexts to describe the direction of movement around a joint. Here’s the difference between the two: Abduction: Abduction refers to a…
What is a Fovea Sign? The ulnar fovea sign is a clinical test used to assess the cause of ulnar-sided wrist pain. It assists in the detection of ulnotriquetral ligament injuries and foveal disruption of the distal radioulnar ligaments. This test is sensitive, meaning it is effective in detecting these specific injuries, and it can…

What Is the Peripheral Nervous System? The peripheral nervous system (PNS) is a vital part of the nervous system, responsible for connecting the central nervous system (CNS) to the rest of the body. It comprises a network of nerves and ganglia that relay information between the brain and spinal cord and the sensory organs, muscles,…
What is the Limited Range of Motion? A Limited Range of Motion (ROM) refers to a restriction or reduction in the movement of a joint or body part. It means that the joint is not able to move through its normal or expected range of motion, either due to stiffness, tightness, pain, injury, or other underlying conditions….
Deep Branch of Radial Nerve Anatomy Origin and Course At the cubital fossa, the radial nerve splits into a superficial (sensory) and deep (motor) branch. The deep branch of the radial nerve extends downhill between the superficial and deep layers of muscles to the center of the forearm after winding around the lateral side of…
The posterior interosseous nerve (PIN) is a branch of the radial nerve, a major nerve in the upper limb. It is an important nerve that supplies several muscles in the forearm, playing a crucial role in hand and wrist movements. After crossing the supinator muscle, it is the deep branch of the radial nerve that…
Introduction The phrenic nerve plays a key part in breathing or respiration. It creates your diaphragm to contract and expand, providing your lungs capacity to inhale and exhale air. Nerve damage can create a paralyzed diaphragm. You may feel short of breath and carry problems sleeping. An irritated phrenic nerve can create persistent hiccups. The…
