The aim of this essay is to clarify the rule of the arthroscopy in the examination and treatment of the anterior glenohumeral instability in young adults.The glenohumeral joint is a classic synovial ball and socket joint
that IS the most mobile j oint in the human body. Yet. it has a very I irrle
inherent stability owing to the shape and contour of the articular surfaces.
It sacrifies stability for the wide range of mobility. Both static and dynamic restraints allow maximum glenohumeral movement while limiting excessive translation of the humeral head over the glenoid.
Static Restraints
Articular Anatomy: 1- Orientation (version)
2- Glenohumeral surface area and articular contact.
3- Glenoid labrum.
II- Capsuloligamentous Structures:1- Rotator interval.
2- Middle glenohumeral ligament.
3- Inferior glenohumeral ligament complex.
4- Glenohumeral capsule.
5- Material properties
- Dvnamic Restraints:
a. Joint compression.
b. Coordinated contraction to steer the humeral head into the glenoid
c. Dvnamization of glenohumeral ligaments through cuff attachment.
Other important dynamic factors include coordinated scapula thorcic rhythm, negative intra-articular pressure and adhesion cohesion.
