As the most mobile joint in the human body, the shoulder is able to perform abduction, adduction, extension, flexion and internal and external rotation. This mobility provides the upper extremity with tremendous range of motion so individuals can engage in sporting activities and perform everyday movements. The shoulder is composed of three joints and five [...]
The shoulder joint is a complex, well-designed structure that allows a great range of motion for the upper extremity. With its significant mobility comes the risk of inflammation, instability, or damage if an injury occurs during sporting activities or from natural degeneration. The rotator cuff is a vital structure located around the shoulder joint and [...]
The rotator cuff, a structure within the shoulder joint composed of four muscle-tendon units, plays an important role in joint function by helping stabilize the shoulder throughout activities of daily living, as well as allowing overhead arm movements for sports and other activities. A shoulder injury to the rotator cuff is usually characterized by a [...]
Pain, weakness and numbness in the shoulder, arm and hand may be associated with a shoulder nerve entrapment syndrome. Two common nerve conditions that affect the shoulder joint and cause discomfort are thoracic outlet syndrome and a suprascapular nerve injury. The main cause of thoracic outlet syndrome is when nerves and blood vessels traveling to [...]
The labrum is a c-shaped rim of fibrocartilage surrounding the glenoid (socket) that serves two vital functions within the shoulder joint. The first function is to deepen the socket so the shoulder remains in place while in motion, while the second function is an attachment site for the biceps tendon and the glenohumeral ligaments. A [...]
A ganglion cyst can occur in any joint, including the shoulder. A ganglion cyst is a fluid-filled mass that lies beneath the skin or muscle near a tendon or joint. Ganglion cysts often form within the body’s deep tissue as one large cyst or a cluster of smaller cysts connected by a common stalk. A [...]
Adhesive capsulitis, more commonly known as frozen shoulder, may be responsible for causing pain and stiffness within the shoulder joint in certain Long Island, Brooklyn, Queens and NYC patients. Over time, many individuals suffering from this condition experience loss of joint mobility as the shoulder becomes more and more difficult to move. It is reported [...]
The shoulder is a sophisticated joint that allows a wide range of motion. As the most mobile joint in the human body, the shoulder is prone to a number of injuries, including rotator cuff tears, dislocations, instability and labral tears. Many patients living in the greater Long Island, Brooklyn, Queens and NYC area undergo an arthroscopic [...]
The shoulder’s anatomy provides the ability for it to turn and move in numerous directions. While this is an advantage, it makes the shoulder an easy joint to dislocate forward, backward or downward. A dislocated shoulder occurs when the ball (humerus head) and socket (glenoid) become separated during a traumatic event or from overuse. A [...]
Many individuals in the greater Long Island, Brooklyn, Queens and NYC area visit Dr. Jonathan Ticker, orthopedic surgeon and shoulder specialist, because they are experiencing bicep pain and shoulder weakness. Biceps tendonitis is a common cause of these two symptoms, and is caused by inflammation of the upper biceps tendon, otherwise known as the long head [...]
