👉 Flexionless is a term used in medicine to describe the condition where the muscles of the shoulder joint are not able to move freely, and they do so by being restrained or restricted. This can occur due to various reasons such as nerve damage, muscle weakness, or even arthritis. In medical context, flexionless conditions often refer to injuries that affect the shoulder joint, which is a complex organ that moves in response to external forces, including weight-bearing tasks like lifting heavy objects and carrying heavy bags
