Missoula Bone and Joint and Surgery Center


The shoulder is an amazing joint, with greater range of motion than any other joint in the body. However, it also lacks stability, which is why it is so easily injured. The shoulder surgeons at Missoula Bone & Joint in Western Montana specialize in treating both acute and chronic shoulder injuries and restoring your mobility.

About the Shoulder Joint

The shoulder is a ball and socket joint. The ball, or the rounded head of the upper arm bone (humerus), fits into the socket (glenoid) of the shoulder blade (scapula). A ring of cartilage called the labrum surrounds the socket to make it deeper. This joint is called the glenohumeral joint. Both the ball and socket are covered in cartilage, which helps the humerus move freely within the joint.

The joint is surrounded by the rotator cuff, a group of muscles and tendons that provide support and stability. A small sac of fluid called a bursa cushions and protects the rotator cuff. The top part of the shoulder, the acromioclavicular (AC) joint, is formed by the collarbone (clavicle) and acromion.

Shoulder Conditions

The shoulder’s complex construction allows for the rotation of the arm in all directions. This attribute also makes the shoulder highly susceptible to injury. Shoulder pain can result in significant problems stemming from several different causes: broken, dislocated, or separated bones; inflamed bursa; inflamed or torn tendons; torn labrum; cartilage degeneration (arthritis); impingement; and more.   

Some of the most common shoulder problems we see and treat include:

Common symptoms of shoulder pain include:

  • Pain with overhead activities (arm above head height)
  • Pain while sleeping at night
  • Pain over the outside of the shoulder/upper arm

When possible, our doctors prefer to address shoulder injuries with nonsurgical treatment such as ultrasound-guided cortisone injections, PRP therapy, or physical therapy, but if you need surgery, you can feel confident that our highly skilled surgeons have the training, experience, and expertise to perform common shoulder surgeries, such as:
