Our shoulder is the most mobile joint in the body.  It is this flexibility of the shoulder that provides the upper extremity with tremendous range of movement that allows us to reach objects overhead as well as behind our back.Being a very mobile joint, shoulder requires considerable support from surrounding muscles and tendons to discharge its function seamlessly.  On the contrary, being a very flexible joint, shoulder is not as stable as some other joints in our body such as hip joint.  So there is no surprise that shoulder is prone to injury, dislocation and separation.  Apart from that, many ...

Shoulder is the meeting place of three bones viz. clavicle, scapula and humerus.  The junction of these three bones and the chest bone (sternum) form three joints: Glenohumeral joint:  It is the shallow ball-and-socket style joint created by the humerus and scapula.  This joint allows the arm to rotate circularly and to move up and out of the body.  Glenohumeral joint is surrounded by soft tissue and strengthened by fibrous ligaments. Acromioclavicular joint (AC joint):  This joint is the highest point of the shoulder.  It is because of this joint that we are able to raise the arm above the ...

Work-related musculoskeletal injuries refer to a host of painful disorders of muscles, tendons, nerves, joints, cartilage and spinal discs.  Work-related musculoskeletal disorders are conditions in which the work atmosphere or performance of work contributes significantly to the condition or an already existing injury is made worse due to work conditions.  Musculoskeletal disorders are coupled with high costs to employers such as absenteeism, loss of productivity and increased health care, disability, and worker’s compensation costs.  Musculoskeletal disorders cases are more severe than the average nonfatal injury or illness. Work activities which are frequent and repetitive or activities with awkward postures lead ...

The shoulder joint is the most mobile joint of the body.  Be it lifting a bucket of water or reaching up into the cupboard, given the number of everyday activities it is involved in, shoulder pain is something that you get from time to time.  Our shoulder has the flexibility to turn in many directions.  But this advantage can be the very disadvantage that makes the shoulder prone to injuries and pain thereafter.  The reasons for shoulder pain can be from osteoarthritis, muscle tears, tendonitis etc.  In fact, there are are numerous possibilities due to the anatomy involved in allowing ...

Many common shoulder problems can be done away with surgery, especially those that are recalcitrant to conservative therapy.  Shoulder surgeries can be quite diverse from minimally invasive arthroscopic procedures, where a scope and surgical instruments are inserted through keyhole incisions in your shoulder, to more traditional open surgeries using scalpel and sutures.  Each approach is different and has its pros, cons, limitations and appropriate uses. Arthroscopy for impingement syndrome: Operation to treat the impingement syndrome accounts for one of the most common reasons of shoulder surgery.  This condition occurs when the tendons of your rotator cuff are trapped intermittently which ...

Axillary nerve palsy is a condition marked by loss of movement or sensation in the shoulder area. There are so many reasons for axillary nerve palsy, but the prominent one is shoulder dislocation. Axillary nerve’s close proximity to the shoulder capsule puts it at risk for injury. It is also known as axillary neuropathy and mononeuropathy as it is a problem with just one nerve. Excessive stress or damage to the axillary nerve, which serves the deltoid muscles and skin of the shoulder, causes axillary nerve palsy. Dysfunction of the axillary nerve can occur in the myelin sheath which provides ...
