Basic Science-Anatomy and Biomechanics

The humerus is the largest bone of upper extremity. The proximal humerus is composed of the humeral head, the greater and lesser tuberosities, the anatomic and surgical necks of the humerus. The humeral head is the most proximal, ball-like region of the humerus that is retroverted (28 to 40 degrees) and articulates with the glenoid […]

Golf injury and Back pain

The most common golf injuries occur in the lower back, elbows, shoulders, hands and wrists, and are generally defined as either cumulative (overuse) or acute (traumatic) injuries. The impact and stress of the repetitive motion of the swing is sometimes hard on the muscles and joints, especially if you ignore the early warning signs of […]

Sprains and Strains

Although the terms sprain and strain are used loosely and have no precise clinical definition, a sprain generally refers to an injury to a ligament – one of the tough, fibrous cords within a joint that connects the bones together, and a strain refers to muscle injury.

Sprains and strains often occur together in or […]

Platelet-Rich Plasma Therapy

What is PRP?

PRP refers to a concentrate of platelets in plasma that is higher than that of normal circulating platelets in the body. Beyond this concept, however, there is considerable variation in its definition.

Platelets have a vital role in the healing of injured tissues. The alpha granules of platelets contain growth factors which […]

Long Head of the Biceps

The long head of the biceps tendon has a variable origin, with 30% to 40% originating at the supraglenoid tubercle, 45% to 60% directly from the labrum, and 25% to 30% from both. It travels obliquely within the shoulder joint, then turns sharply to exit inferiorly beneath the transverse humeral ligament along the bicipital groove. […]

Inferior Glenohumeral Ligament

The IGHL originates on the inferior half of the glenoid neck or anterior inferior labrum, and it inserts inferior to the MGHL on the lesser tuberosity. Various descriptions have been used to define this large, ligamentous structure that undergoes reciprocal tightening and loosening, depending on the position of the arm.

Some have used the terms […]

Coracohumeral Ligament

The CHL originates on the dorsolateral base of the coracoid process and blends with the capsule to the greater and lesser tuberosities. The CHL is present in more than 90% of individuals, and it runs parallel to the SGHL, blending with the superior border of the SGHL inferiorly. Portions of the CHL form the tunnel […]

Acromioclavicular Joint

The AC joint is a diarthrodial joint and the only articulation between the clavicle and scapula. Variable inclinations exist, with being nearly vertical to angled downward and medially accounting for up to 50 degrees. The AC joint has an incomplete fibrocartilagenous intra-articular disc, potentially predisposing it to degenerative changes.

Degenerative changes have been shown to […]

Humerus

The proximal humerus is composed of the humeral head, the lesser and greater tuberosities, the bicipital groove, and the proximal humeral shaft, and it is highly variable. The anatomical neck lies at the junction of the articular surface of the head and the greater tuberosity and humeral shaft. The surgical neck lies below the greater […]

Management-Techniques

The technique and approach of surgical decompression of the suprascapular nerve is dependent on the location of the presumed etiology of the nerve dysfunction. If the pathology is at the suprascapular notch, then the transverse scapular ligament and suprascapular notch may be approached anteriorly, superiorly, or posteriorly.

The anterior approach uses a saber-type incision, just […]
