Description
Technical field
It the utility model is related to bone surgery set field, more particularly to a kind of shoulder joint positioner.
Background technology
Shoulder joint is the complicated joint of mobility maximum in human body large joint, by 3 pieces of bones (clavicle, shoulder blade and humerus),
4 joints (joint and Glenohumeral joint between acromioclavicular joint, articulatio sternoclavicularis, the omoplate wall of the chest) and connect their muscle, tendon and tough
Band composition.Four joint synchronous movement of shoulder under normal circumstances, ensures smooth, the coordination of upper extremity exercise.
Wherein, Glenohumeral joint is physical activity scope maximum, and the minimum joint of bone constraint, it is a bulb (humerus
Head) nest (Scapula glenoid) joint." ball " (head of humerus) is relatively large, and " nest " (Scapula glenoid) is relatively very shallow, this and the height on ball seat
Your husband is similar, so that Glenohumeral joint joint obtains the mobility of maximum, but this also causes shoulder to be easy to injured and produce
It is unstable.Glenohumeral joint relies primarily on the soft tissues such as circumferential cartilage, glenohumeral ligaments, shoulder sleeve and brachial biceps to obtain
Stability.
Shoulder Joint Injury refers to because shoulder is respectively organized to include shoulder sleeve, ligament generation degenerative change, or because excessively making repeatedly
With damages of shoulder joint surrounding tissue caused by reason such as, wounds, shoulder pain is shown as.Common Shoulder Joint Injury has shoulder
Under peak hit disease, rotator cuff injury, frozen shoulder, brachial biceps damage, upper broad-mouthed receptacle for holding liquid lip tear from front to back (SLAP) damage,
Shoulder joint is unstable.
The reason for causing Shoulder Joint Injury mainly have including：Age factor, person in middle and old age are the good hair people of Shoulder joint
Group.As the age increases, respectively tissue includes shoulder sleeve to shoulder, degenerative change occurs for ligament, its tissue elasticity is progressively lost, and becomes
Must be stiff, so as to be more easy to injury；Upper limb excessively is used repeatedly, is another common causative factors of Shoulder joint, is especially engaged in
Upper movement is needed repeatedly to make the crowd of occupation and needed to push the sportsman of work, such as baseball, vollyball, tennis and swimming；
Wound：It is the primary pathogenic factor of young man's Shoulder joint, the damage as caused by traffic accident.
At present, it is increasingly extensive using arthrocsopic surgery treatment shoulder joint associated injury, have in arthrocsopic surgery big
