The supraspinatus muscle.
Shoulder stiffness.
It is a fluid-filled sac that sits subcutaneously over the olecranon process.
Microtears and inflammation.
It extends with the tendon of FPL to the wrist.
Repetitive wrist flexion during activities that require intensive grip.
It usually slips out of the intertubercular groove due to the forceful pull of the muscle.
Very similar to the causes of supraspinatus tendinitis and may be secondary to tendinitis.
Overuse of the tendon, such as excessive throwing motion.
Subcutaneous olecranon bursitis typically presents with unilateral swelling, while rheumatoid arthritis usually presents with bilateral swelling.
It is continuous with the common flexor sheath within the carpal tunnel at the wrist.
Repeated motion of the shoulder above the horizontal causing microtrauma.
Pain along the medial forearm and elbow, and impaired movement of the wrist.
Subacromial bursitis and supraspinatus tendon rupture.
Shoulder impingement syndrome.
A deformity resembling the arm of the cartoon character, Popeye the Sailor.
The tendon of the long head of biceps.
The tendon is surrounded by two layers of synovial membrane, not directly immersed in synovial fluid.
Deep, throbbing pain in the anterior shoulder.
It leads to constant compression of the supraspinatus tendon.
Inflammation of the extensor tendons and periosteum of the lateral epicondyle.
Repetitive microtrauma leads to degenerative changes in the tendon.
Digital tendon rupture due to compression on blood vessels supplying the tendons.
Injury can cause infection to spread to digital synovial sheaths, leading to inflammation.
No, they are separate from each other and from the common flexor sheath.
Forceful flexion of the arm against excessive resistance, often seen in weightlifters.
It rubs against the acromion, causing increased pain.
It is sandwiched between the tendon of the supraspinatus muscle and the acromion of the scapula.
Swelling confined to the infected finger due to independent synovial sheaths.
The supraglenoid tubercle with the GH joint capsule.
The tendons of the flexor digitorium superficialis (FDS), flexor digitorium profundus (FDP), and flexor pollicis longus (FPL).
Lifting, pulling, or repeated overhead motion.
The acromion.
Inflammation of the common flexor tendon.
Inflammation may spread to the bursa, causing fluid buildup and increased pain during movement.
Swelling might also occur at the wrist due to infection spreading along the digital synovial sheath.
Infection, autoimmune diseases (like rheumatoid arthritis), and overuse (repetitive movement).
Repetitive strain from tasks involving loaded and repeated wrist extension.
Usually occurs secondary to biceps tendinitis.
Painful movement at 60° – 120° of abduction.
Direct injury to the shoulder.
Severe degenerative change and calcification of the supraspinatus tendon, usually secondary to tendinitis, and sudden strain of the rotator cuff muscles.
By leaning forward so that gravity causes slight abduction of the arm, allowing the deltoid muscle to take over.
Repeated pressure and friction on the olecranon, infection from abrasions, or a hard blow to the tip of the elbow.
The tendon ruptures.
Fibrous digital sheaths.
Pain or burning sensation along the lateral forearm and elbow, and weakened grip.
From its attachment to the supraglenoid tubercle of the scapula.
No, beyond 120° of abduction, the movement is performed by upward rotation of the scapula.
Very similar to those of supraspinatus tendinitis, specifically painful arc syndrome.
Adherence of the tendon of the biceps long head to the intertubercular sulcus.
Swelling of the skin overlying the olecranon, usually unilateral.
They enter through the gap between the two ends of the synovial sheath.
The lateral epicondyle of the humerus.
A common flexor tendon at the medial epicondyle of the humerus.
A prominent bulge on the anterior aspect of the distal forearm due to the detached long head of biceps.
It normally acts to reduce friction and allow free motion of the rotator cuff.
The patient is totally unable to initiate abduction normally.
