Introduction
Under normal circumstances, the hip joint capsule is composed of membranous connective tissue, which is relatively tough and typically exhibits properties allowing for expansion or contraction, serving as the primary regulator of the cavity's shape and size. Within the hip joint capsule, there is a functional oval opening containing a functional articular labrum that forms a synovial cavity.
Under normal circumstances, the hip joint capsule contains articular labra. The specific details are as follows:
The hip joint capsule is composed of membranous connective tissue, which is relatively tough yet flexible and capable of expansion or contraction. It primarily regulates the shape and size of the joint cavity. Within the hip joint capsule lies a functional oval opening containing articular labra that form gliding chambers. The articular labra are made of cartilage, are soft in texture, and slightly vary in shape.
Generally, up to four articular labra can be found within the hip joint capsule. These labra contact the bone and create four gliding chambers inside the capsule, allowing smoother, more flexible, and freer joint movement. Additionally, the articular labra help resist external pressure, protect the internal tissues of the hip joint, and enhance joint mobility.
In summary, the presence of articular labra within the hip joint capsule normally serves to protect joint function. However, diseases may cause labral tears, significantly affecting joint function. Therefore, patients should seek timely medical attention and early treatment to prevent worsening of the condition.
