The Anatomy of the Shoulder | Shoulder Pain in Lake St. Louis, MO
The shoulder is among the largest and most intricate joints we have. In reality, it is made up of four independent smaller joints:
- The glenohumeral (GH) joint is a ball and socket joint responsible for connecting the upper extremity to the trunk. Given the relatively shallow dish, it has the widest range of motion as any other human joint.
- The acromioclavicular (AC) joint is formed by the junction of the clavicle the acromion, the bony tip on the outer edge of the shoulder blade. A gliding joint, it allows you to outstretch your arm.
- The sternoclavicular (SC) joint is a plane-style synovial joint located where the clavicle meets the sternum at the bottom of the neck. This joint is where the arm and body meet, it connects the movement of the upper limb with the core of your body.
- The scapulothoracic (ST) “joint” is more of a “floating” joint as it does not have ligaments connecting it to bone. It is made up of the scapula and its articulation with the ribcage.
The shoulder is supported and surrounded by:
- the four muscles of the rotator cup that surround the head of the humerus, which power movement and keep the head of the upper arm bone firmly within the shallow socket of the shoulder
- the shoulder capsule, a tough sheath or membrane that encloses the joints in the shoulder
- the ligaments of the shoulder which provide passive stability while still allowing for movements in different planes
- the biceps tendon and rotator cuff tendons which allow muscles to power the bones
- the brachial plexus nerves that allow the brain to tell the shoulder and arm to move and the shoulder to tell the brain when it feels pain or other sensory information
- the arteries that supply much-needed blood to the muscles, ligaments, and tendons
Optimal shoulder and movement health depends on every part of the system functioning well. Blood must flow freely to the shoulder maintain healthy soft tissue and stimulate the body’s natural recovery processes. The muscles must have adequate strength and flexibility, the tendons connecting them to the bones must be strong, flexible, and free of rips or tears, the ligaments connecting bones need to be similarly healthy, and the nerves need to have a strong and secure connection to the brain. When any one of the parts of the shoulder is damaged, inflamed, or otherwise irritated, it can lead to a breakdown of the whole complex, and anywhere from nagging to severe shoulder pain or loss of function. If you’re experiencing shoulder pain or any other symptoms of a shoulder injury, contact Axes’ physical therapists for a no-risk, no-obligation injury screening.

What Causes Shoulder Pain?
As the shoulder is complex, shoulder pain can have any of a number of root causes, from sports injuries to falls, a work injury from repeated activities to old age. Below are the most common underlying conditions that lead to shoulder pain in Lake St. Louis, MO:
- Bursitis — The bursae are small, fluid-filled sacs that work as a cushion and gliding surface between tissues. Bursitis the result of the bursae becoming irritated after overuse, often occurs in combination with irritation of the rotator cuff, and can make daily tasks like getting in and out of cars tremendously difficult.
- Tendinitis — Tendinitis generally occurs because of a tendon becoming irritated. There are two types of tendinitis:
- Acute: The result of trauma, excessive overhead motions, or other overhead activities needed in some competitive and activities and occupations, such as tennis or lifting boxes above your head.
- Chronic: This can happen because of wear and tear or the body becoming weaker as we age.
The condition causes pain and tenderness just outside the joint.
- Rotator Cuff Tear — These can also be caused by acute injuries, like lifting an incredibly heavy object, or more chronic in nature. The tendon is initially frayed before becoming torn. A partial thickness tear often goes unnoticed. Full-thickness tears, which pull the tendon off the bone, do not heal by themselves. Common symptoms are pain when performing specific movements, pain when sleeping, and a clicking sensation with certain movements.
- Shoulder Impingement — Impingement describes when your acromion (outer edge of your shoulder blade) irritates the rotator cuff and bursae. It often occurs in combination with an injury that causes inflammation in the rotator cuff. Shoulder impingement is most common in people who play sports or are otherwise active.
- Shoulder Instability — This occurs when the head of the humerus is allowed to move out of the socket when the capsule or ligaments become stretched, torn, or detached, and also can happen suddenly or from overuse. Dislocations can be repeated and partial or the entire bone coming out of the socket. It often causes or is the result of injury to the surrounding areas of the shoulder. Chronic instability will result in shoulder pain and a sense of the shoulder “giving way.”
- Arthritis — While arthritis refers to a range of diagnoses, the shoulder most typically suffers from osteoarthritis. Osteoarthritis is the degeneration of joint cartilage and the underlying bones. It can be the result of old age, persistent injuries, and wear and tear. There is no cure for arthritis, but you can find effective pain management methods with Lake St. Louis, MO physical therapists.
- Shoulder Fractures — The upper arm bone, collarbone, and scapula are the most commonly broken bones in the shoulder. They are often the result of falling a significant distance or onto a hard surface or forceful collisions such as a car accident. The shoulder pain is immediate and obvious, along with considerable swelling and bruising.
- Axillary Nerve Injuries or Brachial Plexus Injuries — Nerve damage in the shoulder can occur when nerves are impinged on, when scar tissue interferes with signals between the brain and shoulder, or the nerves rupture. These injuries can cause shoulder pain along with a range of other sensations. They are usually the result of high-impact trauma but can also occur because of degenerative conditions.
At times, one injury leads to another, such as how an untreated rotator cuff tear can lead to arthritis.
