Understanding Shoulder Clavicle Anatomy and Function

Have you ever noticed a small bump or a tiny bone near your shoulder and also wondered what it is? That’s your clavicle, or you can say collarbone. The clavicle, also called the collarbone, keeps your arm connected and supported, making shoulder movement possible. Even though it’s tiny, but it really helps you move and stay stable with utmost ease. Learning about your clavicle’s structure can help you understand why shoulder pain or injuries occur.

In this blog, we’ll learn about the reasons behind clavicle pain. Also, how this important bone works, and share tips to protect and support your shoulder. So you can move comfortably again.

What is the Clavicle?

The clavicle is a long, slender bone located at the top of the chest. It runs horizontally from the sternum (breastbone) to the shoulder blade (scapula). Because of its position, it forms part of the shoulder girdle, linking the upper limb to the axial skeleton.

Many people refer to the clavicle as the collarbone, and both terms are correct. But if you notice properly "clavicle" is the anatomical term, while "collarbone" is more commonly used in everyday language. The clavicle is a long bone that is specifically classified as an S-shaped long bone. This helps protect your shoulder by absorbing shocks while you move your arm.

Clavicle Location

The clavicle is positioned just above the first rib. It sits horizontally, forming a noticeable ridge under the skin. So that you can feel it at the base of your neck, extending toward the shoulder.

The lateral end of the clavicle connects to the scapula at the acromion, forming the acromioclavicular joint. The medial end attaches to the sternum at the sternoclavicular joint. These joints allow the shoulder to move freely in multiple directions.

Function of the Clavicle

The clavicle has three main functions:

1. Support: It keeps the shoulder away from the chest wall, allowing a wide range of arm movement.
   
   
2. Protection: It shields nerves and blood vessels that run beneath it, especially those supplying the arm.
   
   
3. Force Transmission: It transfers forces from the arm to the axial skeleton, helping absorb shocks during lifting or falls.

The clavicle plays a key role, and without this bone, it would be quite difficult for you to move your arm freely. The shoulder would lose stability, making daily activities difficult for you to perform.

Types of Clavicles

Everyone has two clavicles that look the same on both sides. Minor differences are completely normal.

While in rare conditions or you can say cases, congenital differences like an absent or unusually curved clavicle do occur. Despite these differences, the clavicle's function remains essential.

Shoulder, Clavicle, and the Clavicle Shoulder Joint

The clavicle forms part of the shoulder joint complex. It connects to two critical joints:

• Sternoclavicular Joint (SC Joint): This joint links the clavicle to the sternum. It allows small but essential movements that help the shoulder rotate and lift.
  
  
• Acromioclavicular Joint (AC Joint): This joint connects the clavicle to the scapula. Injuries to this joint are common in sports and falls.

These joints make the shoulder one of the most flexible regions in the human body.

Common Issues Involving the Clavicle

The clavicle is prone to injury because of its exposed position. Some common problems that may arise include:

• Broken Clavicle (Fracture): This occurs quite often when you play sports or fall during accidents. A broken collarbone doesn’t always mean your shoulder is broken, but it can affect how it moves. The symptoms vary that include Pain, swelling, and a visible bump, which are common.
  
  
• Pain or Tenderness: Pain in the clavicle area can result from muscle strain, arthritis, or inflammation at the joints.
  
  
• Lumps on Clavicle: Sometimes, a lump may appear near the shoulder. Causes include bone spurs, cysts, or fractures. Medical evaluation is necessary.

What’s Behind That Nagging Clavicle Pain?

You’re probably thinking, Why is my shoulder clavicle hurting? Pain in the clavicle region can result from several causes, and that includes:

• Muscle strain from heavy lifting or poor posture.
  
  
• Joint inflammation in the AC or SC joints.
  
  
• Fractures due to trauma or falls.
  
  
• Nerve compression causing shoulder pain is uncommon, but it can happen in rare cases.

Proper diagnosis is very important on time. Consulting an orthopedic specialist can help determine the exact cause.

Difference Between Clavicle and Collarbone

Anatomically, the clavicle and the collarbone are the same. The term "collarbone" is simply a layperson’s term for the clavicle. Some confusion arises because the clavicle is part of the shoulder, but it needs to be noted that it does not constitute the entire shoulder joint.

If you Understand this distinction, especially when discussing injuries or treatment options, you will get the clear difference between these.

Healing and Support for Clavicle Injuries

In cases of clavicle fractures or shoulder injuries, proper support is very important. Products like Leeford Ortho Shoulder and Arm Supports provide effective stabilization.

Stabilization: Keeps the clavicle and shoulder joint aligned during healing phase.

Pain Relief: Gently supports healing of muscles and ligaments, helping recovery feel very comfy.

Mobility Support: Supports gentle motion without causing pain, also no more stiffness.

Skin-friendly: Comfy enough, so that you can wear it all-day wear, without any annoying itching.

Using a proper orthopedic support helps you in various ways such as it helps reduce recovery time and improves functional outcomes after clavicle injuries.

Clavicle in the Human Body

The clavicle is part of the shoulder girdle, which includes:

• Scapula (Shoulder Blade)
  
  
• Humerus (Upper Arm Bone)
  
  
• Associated Muscles: Deltoid, trapezius, pectoralis major

These parts of your body coordinate to make lifting, throwing, and reaching smooth and safe.

Clavicle Area and Shoulder Collar: The area that is around the clavicle is often called the shoulder collar, including muscles, ligaments, and joints that provide stability and flexibility. 

Identifying Clavicle Problems

Signs of clavicle issues include:

• Pain at the top of the shoulder
  
  
• Swelling or bruising
  
  
• Limited arm movement
  
  
• Visible deformity or lump near the shoulder

If you notice any of these symptoms, seek medical advice immediately.

Diagnosing Clavicle Injuries

Doctors usually check for these issues with the following tests:

• Physical Examination: Checking for tenderness, deformity, and mobility.
  
  
• X-rays: To identify fractures or dislocations.
  
  
• MRI or CT Scans: For detailed imaging of soft tissue and joint structures.

Treatment Options

Treatment depends on the type and severity of the injury:

1. Conservative Management:

• Rest and immobilization
  
  
• Pain relief medications
  
  
• Leeford Ortho shoulder slings for support
  
  

2. Surgical Intervention:

• Required for severe fractures or misaligned bones
  
  
• Post-surgery, orthotic support is recommended

• Gentle exercises to restore mobility
  
• Strengthening muscles around the shoulder
