For many decades, the physical mechanism that causes the cracking sound as a result of bending, twisting, or compressing joints was uncertain. Suggested causes included: Cavitation within the joint—small cavities of partial vacuum form in the synovial fluid and then rapidly collapse, producing a sharp sound. [7] [8] Rapid stretching of ...
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 ...
Adhesive capsulitis (AC), also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. [1] It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. [3] There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple ...
In some cases, an audible snapping or popping noise as the tendon at the hip flexor crease moves from flexion (knee toward waist) to extension (knee down and hip joint straightened). It can be painless. [2] After extended exercise, pain or discomfort may be present caused by inflammation of the iliopsoas bursae. [3]
Impingement of the shoulder was previously thought to be precipitated by shoulder abduction and surgical intervention focused on lateral or total acromionectomy. [4] [25] In 1972, Charles Neer proposed that impingement was due to the anterior third of the acromion and the coracoacromial ligament and suggested surgery should be focused on these ...
The contractions are very rapid, occurring as often as 150 times a minute, and may persist during sleep. The condition usually appears in adults and can last indefinitely. People with palatal myoclonus usually regard it as a minor problem; some complain of an occasional "clicking" sound, a noise made as the soft palate muscles contract.
The scapula (pl.: scapulae or scapulas [1]), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other.
Anterior shoulder dislocation while carrying a frail elder. A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa. [2] Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1]
