Glossary

Caring for patients with a myriad of shoulder complaints, our philosophy is to educate patients about their conditions to allow them to take control of their ailments. We hope this section offers you insight.

Acromion
Part of the scapula, forms the roof above the supraspinatus tendon. Often has a hooked configuration that impinges on the supraspinatus tendon.

Adhesive Capsulitis A condition whereby the ligaments connecting the top of the humerus and the glenoid become inflamed and thickened leading to a painful tight shoulder.

Arthritis Inflammation in a joint that often accompanies arthrosis.

Arthroscopy Using a pencil sized camera to visualize and treat problems within a joint.

Arthrosis (Arthritis) The loss of articular cartilage so that the underlying bone is exposed.

Articular Cartilage The smooth covering of the ends of the bones in a joint. An everyday example is the articular cartilage found on the end of the knob of a chicken leg.

Biceps A muscle that runs up the front of the humerus and attaches the scapula to the forearm. It has two insertions on the scapula: the short head attaches to the coracoid process and the long head attaches to the top of the glenoid.

Bursa A slippery tissue designed to decrease the friction that resides between two moving surfaces. Often becomes inflamed and thickened.

Clavicle The collar bone.

Coracoid Part of the scapula, insertion point for the short head of the biceps and can impinge on the subscapularis tendon.

Deltoid A powerful muscle originating off the acromion and inserting on the humerus. It supplies the majority of the power in lifting the arm.

Dislocation When the top of the humerus comes out of the socket.

Frozen Shoulder Same as Adhesive Capsulitis.

Glenoid Part of the scapula, forms the socket of the shoulder joint.

Humerus The upper arm bone that connects the shoulder blade to the elbow.

Labrum The rim of cartilage surrounding the glenoid on which the long head of the biceps tendon attaches as well as the ligaments connecting to the top of the humerus.

Rotator Cuff A group of four muscles (subscapularis, supraspinatus, infraspinatus, and teres minor) that originate off the scapula. Their respective tendons form a cuff of tissue that inserts on the top of the humerus. They rotate the humerus but their primary role is to keep the top of the humerus centered on the glenoid.

Scapula The shoulder blade.

Separation When the ligaments connecting the acromion and clavicle are injured.

SLAP Tear A tear of the labrum involving the superior aspect of the labrum where the biceps tendon inserts.

Snapping Scapula Known as scapulothoracic bursitis, this conditions causes a painful crunching sensation in the upper back under the shoulder blade.
