Acromioclavicular joint

A synovial plane joint between the acromion of the scapula and the lateral end of the clavicle. Its strength comes from the coracoclavicular ligament, which suspends the scapula and the whole limb from the clavicle.

اہم نکات

• Synovial plane joint: acromion + lateral clavicle.
• Coracoclavicular ligament (conoid + trapezoid) carries the weight of the limb.
• Nerve: suprascapular.
• Shoulder separation = torn coracoclavicular ligament.
• Joint: from mesenchyme between bone ends.
• Synovial cavity forms in the middle layer.
• Synovial membrane: type A (phagocytic) + type B (secretory) cells.
• Joint surfaces: hyaline cartilage, no perichondrium.
