Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus muscle. [1] This can result in pain, weakness, and loss of movement at the ...
Muscle loss around the shoulder may also occur. [1] Onset is gradual over weeks to months. [2] Complications can include fracture of the humerus or biceps tendon rupture. [2] The cause in most cases is unknown. [1] The condition can also occur after injury or surgery to the shoulder. [2] Risk factors include diabetes and thyroid disease. [1] [4 ...
A flattened or hooked acromion can predispose a shoulder to rotator cuff impingement and tearing. Well-documented anatomic factors include the morphologic characteristics of the acromion, a bony projection from the scapula that curves over the shoulder joint.
More commonly, subacromial bursitis arises as a result of complex factors, thought to cause shoulder impingement symptoms. These factors are broadly classified as intrinsic (intratendinous) or extrinsic (extratendinous). They are further divided into primary or secondary causes of impingement.
Risk factors that increase the chance of developing calcific tendinitis include; hormonal disorders, like diabetes and hypothyroidism, autoimmune disorders, like rheumatoid arthritis, and metabolic disorders that also cause kidney stones, gallstones, and gout. Occupations that consist of repetitive overhead lifting, such as athletes or ...
Risk factors: Anterior shoulder dislocation and/or repeated anterior shoulder subluxations. [2] Diagnostic method: X-ray and MRI. Differential diagnosis: Anterior labroligamentous periosteal sleeve avulsion, Rotator Cuff Tears, SLAP Lesion, Impingement, Perthes lesion, Glenolabral articular disruption, Humeral avulsion of the glenohumeral ...
Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...
Bad posture and age are leading risk factors, with a high prevalence of asymptomatic partial and full tears, as well as symptomatic syndromes with chronic pain. Associated pathologies include acromial impingement , frozen shoulder , and poor sleep, especially on the affected side.
