What is superior translation?
a person or group of people who are higher in rank or social position than others: I will pass your complaint on to my superiors. Synonym. higher-up informal.
What is humeral head migration?
This migration of the humeral head upward is also called a superior subluxation because the ball is not in its proper position (subluxed). In some individuals the humeral head may not only migrate upward, but it may also migrate toward the front of the shoulder (called anterior migration or subluxation) as well.
What causes humeral head migration?
Discussion: Superior humeral head migration was associated with the fatigued state. This implies that overhead or repetitive work, or both, may accelerate the development of subacromial impingement through reduction of the subacromial space.
What is an inferior shoulder dislocation?
An inferior shoulder dislocation is the least common form of shoulder dislocation. The condition is also called luxatio erecta because the arm appears to be permanently held upward, in fixed abduction. The patient will often present with their hand placed on the head or near it.
Do subscapularis tears really result in superior humeral migration?
Subscapularis tears do not lead to superior humeral migration and subacromial impingement, but superior rotator cuff tears, and, therefore, intact subscapularis tendon does not prevent superior humeral migration and subacromial impingement caused by superior rotator cuff tear.
When I lift my arms one shoulder is higher than the other?
Uneven shoulders can also happen when you have structural issues or muscular skeletal imbalances in the body. This may include legs that vary in length or scoliosis. Uneven shoulders can also be the result of an imbalance somewhere else in the body. Think of it as a domino effect.
Why does my shoulder keep coming out of socket?
Shoulder instability usually occurs when the lining of the shoulder joint (the capsule), ligaments or labrum become stretched, torn or detached, allowing the ball of the shoulder joint (humeral head) to move either completely or partially out of the socket.
Why does the bone on the top of my shoulder stick out?
Bone spurs (also called osteophytes) consist of excess bone growth around your joints, and are common in older adults. Bone spurs in the shoulders may develop as a result of degenerative joint conditions as well as injuries and general wear and tear. At first, a bone spur in the shoulder may not present any symptoms.
What does an unstable shoulder feel like?
Signs of shoulder instability Shoulder pain due to injury. A loose or hanging feeling in the shoulder joint. The sensation of your arm bone slipping out of joint.
Can a dislocated shoulder be fixed without surgery?
Closed Reduction Most people who experience a shoulder dislocation seek immediate treatment in an emergency room, where a doctor can put the round end of the arm bone, or humerus, back into place without surgery.
Are there different levels of dislocated shoulder?
Your shoulder can be either partially or completely dislocated. A partial dislocation is when the head of your upper arm is partially out of your shoulder socket. Complete dislocation is when the head of your upper arm is completely out of your shoulder socket.
Which is worse anterior or posterior shoulder dislocation?
Posttraumatic degeneration of the glenohumeral joint is relatively uncommon after posterior dislocation, but when it occurs the severity of the arthrosis is usually worse than that following anterior dislocation.
What is the definition of humeral head?
The head of the humerus is the proximal articular surface of the upper extremity, which is an irregular hemisphere. It articulates with the glenoid fossa of the scapula. The anatomical neck is the part between the head and the tuberosities. The surgical neck is the part between the tuberosities and the shaft.
What is the humeral head?
The humerus bone is located in the upper arm, between the shoulder joint and the elbow joint. The shoulder joint, also known as the glenohumeral joint, is a ball and socket joint. The ball is the humeral head, and the socket is the glenoid fossa of the scapula.
What causes humeral head pain?
Humeral head osteonecrosis can be caused by either traumatic or atraumatic means. Traumatic causes of osteonecrosis may include proximal humerus fractures as well as iatrogenic injury from surgical fixation or arthroscopy.
What does high riding humeral head mean?
A high-riding shoulder refers to the superior displacement/subluxation of the humeral head with resultant decrease in the acromiohumeral distance. The differential for a high-riding shoulder is: rotator cuff tear with or without rotator cuff arthropathy.
Migration: Superior and Anterior Superior [Shoulder]
Are there any operations to help regain motion? The answer to this question is difficult. For patients with superior or anterior-superior subluxation, the most difficult part to solve with surgery is the loss of motion and function.
Superior humeral head migration occurs after a protocol designed to ...
Hypothesis: Awkward postures and repetitive work have been suggested to lead to shoulder fatigue, which may in turn decrease the subacromial space. The aim of this study was to quantify changes in humeral head position relative to the glenoid after rotator cuff fatigue.
Shoulder Subluxation: Symptoms, Treatment, and More - Healthline
Shoulder subluxation refers to a partial dislocation of your shoulder. Here’s why this happens, tips for identification, treatment, and more.
What is superior migration?
Superior or anterior-superior migration of the shoulder is generally seen in two types of patients. The first are those with relatively large rotator cuff tears where one or multiple tendons are completely missing, whereas in the second category are those who have had unsuccessful shoulder replacement surgery and as a result the rotator cuff tendons get weak.
How to treat shoulder pain?
One strategy is to avoid the activities that trigger the symptoms, particularly heavy lifting or trying to carry heavy objects away from the body. Another method is to treat the pain with ice or heat; whichever ameliorates the pain. Ice packs are more suited if the shoulder is sore.
Abstract
We illustrate a patient with a migrating lumbar disc fragment that caused a change in radicular symptoms from the L3 nerve root on one side to the L5 nerve root on the contralateral side, documented by magnetic resonance imaging (MRI). Our patient presented with 3 months of L3 pain on the right side with sensory and motor changes.
1. Introduction
Lumbar disc disease is common, and symptomatic lumbar disc herniation has been recognised for over 70 years.
2. Case report
A 32-year-old man initially presented with three months of severe right-sided buttock and lateral thigh pain. He sought medical advice when he noticed that when walking down stairs, he lost power in the thigh and would nearly fall.
3. Discussion
Disc herniation is defined as a localised displacement of disc material beyond the limits of the intervertebral disc space. The disc material may be nucleus, cartilage, fragmented apophyseal bone, annular tissue, or any combination thereof.
What is superior migration?
Superior migration of the shoulder is a relatively rare condition seen in two types of patients: 1) those with large rotator cuff tears where a tendon is missing, and 2) those who have had unsuccessful shoulder replacement surgery. Symptoms of superior or anterior-superior migration of the shoulder include loss of arm motion ...
How is superior or anterior-superior migration diagnosed?
This condition can be diagnosed by your physician based upon your history, physical examination, and radiographs ( X-rays ). Some but not all patients with this condition will have a history of an injury to the rotator cuff. This condition is common in patients who have had surgery for large tears of the rotator cuff that have failed to heal or to stay repaired.
What is migration of the shoulder?
The shoulder is a ball-and-socket joint. The ball is the humeral head that is at the end of the humerus or arm bone. The socket is part of the shoulder blade and is flat. The ball is much larger than the socket, and some say that a good analogy is that the humeral head on the socket is like a beach ball on a dinner plate.
What are the signs or symptoms of a superior or anterior-superior migration?
One of the main signs of a superior subluxation is that the arm loses its motion. When a person with this condition goes to lift their arm, they can only raise it about one-third of the way up , or around 60 to 70 degrees . In shoulders with anterior-superior subluxation, you may actually see a prominence on the front of the shoulder as the ball rides up and forward. This inability to raise the arm is the reason that this condition limits a person’s ability to use the arm. This loss of ability to lift the arm above shoulder level makes it difficult to reach into cabinets or to the back of the head.
Why is the humeral head called superior subluxation?
This migration of the humeral head upward is also called a superior subluxation because the ball is not in its proper position (subluxed). In some individuals the humeral head may not only migrate upward, but it may also migrate toward the front of the shoulder (called anterior migration or subluxation) as well.
Where is the supraspinatus tendon located?
The supraspinatus tendon is actually a large tendon. It is about as thick as your little finger and as wide as your middle three fingers. In the shoulder, it is located between the ball of the arm bone (humerus) and a part of the shoulder blade called the acromion.
Is the humeral head bigger than the socket?
The ball is much larger than the socket, and some say that a good analogy is that the humeral head on the socket is like a beach ball on a dinner plate. The ball is held into the socket by several things, including the muscles, the ligaments, the labrum and the rotator cuff.
