What causes bone loss in shoulder?
repetitive injuries to the AC joint or distal clavicle. repetitive motions with heavy weights (hence the name “weight lifter’s shoulder”) a combination of the long-term wear on the shoulder joint combined with some predisposing joint condition, such as rheumatoid arthritis.
How is glenoid bone loss calculated?
The line between the anterior margin of the circle and the anterior margin of an injured glenoid represents the size of the osseous loss. The size of the bone defect divided by the glenoid width and multiplied by 100 represents the percentage of glenoid bone loss [17].
What is Latarjet shoulder procedure?
The Latarjet procedure is a technique used to restore stability to the shoulder joint. Developed by a French surgeon in the 1950s, it is commonly performed when there is significant bone loss in the front of the glenoid (the shallow socket in the shoulder blade) from repeat dislocations.
What is glenoid Retroversion?
Glenoid retroversion is the abnormal posterior angulation of the articular surface of the glenoid of the scapula and is of importance as it predisposes to posterior glenohumeral instability and tears of the posterior labrum.
Can you get osteoporosis in your shoulders?
Patients with osteoporosis do not typically experience symptoms in the early stages of bone loss, but can experience signs and symptoms when the condition has weakened bones, including bones which comprise the shoulder: Shoulder blade (scapula) fracture.
Can you have a shoulder replacement with osteoporosis?
Severe fractures—Because a severe fracture of the shoulder may be extremely difficult to piece back together, and the blood supply to the pieces of bone may be interrupted, a shoulder replacement may be recommended. Older patients with osteoporosis are most at risk for this type of fracture.
How is bone loss in the shoulder calculated?
Glenoid bone loss is percentage reduction in osseous defect area (Area A) relative to area of best-fit circle (Area A + Area B), that is, Area A/(Area A + Area B) × 100%.
What is glenoid bone?
The glenoid is the socket part of the ball-and-socket shoulder joint. It’s part of the scapula (shoulder blade), which is a thin, broad bone that sits behind the rib cage.
What is Bristow Latarjet?
The Bristow-Latarjet procedure is a well-known surgical technique designed to treat shoulder instability. In this procedure, the coracoid process is transferred to the glenoid rim, to serve as augmentation of an associated bony defect.
Is Latarjet surgery painful?
A nerve block may be used during the surgery. This means that immediately after the operation the shoulder and arm often feel completely numb. This may last for a few hours. After this the shoulder may well be sore and you will be given painkillers to help this whilst in hospital.
What is humeral Retrotorsion?
Humeral retrotorsion describes the bony architecture that occurs when the head of the humerus is oriented in a posterior medial direction and is associated with a transverse plane rotation within the humerus (Figure 1).
Is the scapula?
The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.
