STRUCTURE OF THE SHOULDER COMPLEX: STRUCTURE OF THE SHOULDER COMPLEX FAIZA KHATOON.H BPT(2 ND YEAR) PowerPoint Presentation: ADHESIVE CAPSULITIS Adhesive Capsulitis is a condition characterized by pain and progressive limitation of some movements of the shoulder joint mostly occuring in the elders. It is also called as “FROZEN SHOULDER” (LOYD JA,LOYD HM:1983) TYPES PRIMARY idiopathic SECONDARY (cause of this type is (occurs in diabetic, not known ) tuberculosis, hemiplegia patient. SHOULDER SHOULDERCOMPLEX: SHOULDER SHOULDERCOMPLEX The Shoulder Complex, composed of clavicle, scapula & humerus that links the upper extremity to the thorax. Shoulder Complex consists of: Glenohumeral Joint Acromioclavicular Joint Sternoclavicular Joint Scapulothoracic Joint Osteo-kinematic movements: JOINTS TYPE MOTION MUSCLES (PRIME MOVERS) Glenohumeral joint Ball & socket Abduction Flexion Deltoid,Bicep-brachi Coraco brachialis, Pectoralis major Acromio-clavicular joint plane Rotation Scapula tilting Trapezius, Serratus anterior Levator scapulae, Rhomboidus minor & major. Sterno-clavicular joint plane Elevation, Protraction Trapezius, Levator scapulae Serratus anterior, Pectoralis major Scapula-thoracic joint - Depression Adduction Lattismus dorsi, Subclavius Pectoralis major, teres major Osteo-kinematic movements PowerPoint Presentation: LIGAMENTS Capsule: Capsule (Surrounds the joint) Medially – glenoid fossa Laterally – anatomical neck of the humerus Capsule is made up of Synovial & Fibrous Layer. Synovial membrane lines inner surface of the capsule & produces Synovial fluid to reduce friction. ASPECTS STRUCTURES AROUND THE CAPSULE superiorly Coraco-humeral ligament inferiorly Capsule is thin & weak Anteriorly Glenohumeral ligament & subscapularis tendon posteriorly Teres minor & infraspinatus tendon Rotator cuff: Rotator cuff Rotator cuff provides active support for joint. Rotator cuff is the musculo-tendinous complex. Role of capsule : Role of capsule Gleno-humeral capsule & ligaments provides stability to the joint. The stabilizing function is minimal at less than 90* of humeral elevation . Rotator cuff muscles & tendons a ctively stabilizes the joint.
