Shoulder Exam I

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA Examination of the shoulder can be complex, because it actually consists of four separate joints: are the glenohumeral (GH) joint, the acromioclavicular (AC) joint, the sternoclavicular joint, and the scapulothoracic joint. The GH joint is primarily responsible for shoulder motion and is the most mobile joint in the body. It has been likened to a golf ball sitting on a tee and is prone to instability. It is held in place...

We used synchrotron X-ray tomography at the European Synchrotron Radiation Facility (ESRF) to non-invasively produce 3D tomographic datasets with a pixel-resolution of 0.7µm. Using volume rendering software, this allows the reconstruction of internal structures in their natural state without the artefacts produced by histological sectioning.

FAQs
Its seal around the femoral head supports joint congruence, meaning the contacting surfaces remain well aligned as the hip moves. The labrum also helps maintain fluid pressure within the joint. Together, these functions contribute to stability and allow the hip to manage movement while protecting its articular surfaces.
The labrum helps distribute forces across the hip joint rather than allowing stress to concentrate on limited areas. By supporting congruence between the femoral head and acetabulum, it promotes efficient contact during movement. Disruption of these roles can increase mechanical strain and contribute to damage of the articular cartilage.
Injury or degeneration can weaken the labrum’s stabilizing and sealing functions. As a result, the hip may experience altered joint mechanics, with symptoms such as pain, clicking, or instability. Because the labrum also helps protect articular surfaces, impairment may contribute to cartilage damage over time.
Knowledge of the labrum’s position around the hip socket and its biomechanical roles helps clinicians relate symptoms to possible structural problems. Assessment and imaging can then be interpreted in the context of pain, clicking, instability, or suspected cartilage involvement, rather than treating the labrum as an isolated anatomical finding.
Hip arthroscopy is one treatment approach identified for acetabular labral problems. Understanding the labrum’s anatomy and its contribution to stability, sealing, and load distribution helps place arthroscopic treatment within the broader clinical picture. The approach is relevant when evaluation indicates that labral pathology may be contributing to hip symptoms or impaired mechanics.
Labral repair and reconstruction are treatments intended to address acetabular labral dysfunction while considering the structure’s mechanical roles. Treatment planning relies on clinical assessment and imaging, together with an understanding of how the labrum supports congruence, fluid pressure, stability, and protection of the hip’s articular surfaces.
