Shoulder Joint Tears (Glenoid Labrum Tear)

Anatomy

The shoulder is a ball-and-socket joint made up of three bones: the humerus (upper arm bone), the scapula (shoulder blade), and the clavicle (collarbone). The head of the humerus fits into a rounded socket in the scapula, known as the glenoid. The labrum is the strong, fibrous tissue on the outside edge of the glenoid which helps to deepen the socket and stabilize the shoulder joint. A labral tear occurs when the labrum is disrupted, frayed, or torn. 

Causes of Shoulder Labral Tears

Injuries to the ring of cartilage surrounding the shoulder socket can occur from acute trauma or repetitive shoulder motion. They are common in athletes who throw a ball or perform other shoulder motions repeatedly, such as weightlifters. Causes of labral tears include:

  • Falling on an outstretched arm
  • A direct blow to the shoulder
  • A sudden pull, such as when trying to lift a heavy object
  • A violent overhead reach, such as when trying to stop a fall or lide
  • Trauma, such as a fracture or dislocation
  • Overuse
  • Repetitive motion

Types of Shoulder Labral Tears

Shoulder labral tears can happen anywhere around the glenoid socket. The two main types of shoulder labral tears are:

  • Slap tear or lesion: When the tear is above the middle of the glenoid. SLAP tears are common in tennis players, baseball players, and anyone who uses a lot of overhead arm movements.
  • Bankart tear or lesion: When the tear is in the lower half of the glenoid. Bankart tears are more likely to occur in younger people with dislocated shoulders. 

Symptoms of a Shoulder Labral Tear

The most common symptoms associated with a labral tear in the shoulder include:

  • Pain when performing overhead activities
  • A sense of instability in the shoulder
  • Grinding, popping, or sticking in the shoulder socket
  • Occasional pain at night or pain with daily activities
  • Decreased range of motion
  • Loss of shoulder strength

How is a Shoulder Labral Tear Diagnosed?

To diagnose a shoulder labral tear, your Raleigh Orthoapedic physician  will ask about your symptoms and what you were doing before the injury occured. You will be asked to perform a series of movements to find the source of your pain. Imaging tests, such as an X-ray will be ordered to rule out a fracture to the shoulder. The rim of the shoulder socket is soft tissue so damage will not show up on an x-ray. An MRI will be ordered, sometimes with a dye injected to help detect tears and diagnose if arthroscopic surgery is needed. 

Treatment for Shoulder Labral Tears

Treatment for labral tears usually begins with conservative methods before surgical intervention is suggested. If surgery is needed, your Raleigh Orthopaedic physician can utilize arthroscopy, a minimally-invasive procedure, to treat a labral tear. 

Nonsurgical Treatment

A labral tear won’t heal on its own, but rest and other measures can help manage symptoms of a minor tear. Nonsurgical treatment for a labral tear includes:

  • Rest
  • Anti-inflammatory medicationMedications such as non-steroidal anti-inflammatories such as ibuprofen and naproxen can reduce pain and inflammation
  • Steroid injections Injection of a corticosteroid along with a local anesthetic may relieve symptoms temporarily or permanently in the shoulder joint. If pain returns, another injection may be needed. Your doctor can inject a steroid into the hip joint to ease symptoms
  • Physical therapy – Specific exercises can help strengthen the rotator cuff muscles

If you are experiencing deep pain in your shoulder area that is not improving with rest, lasting more than two weeks, and interfering with your normal activities, consult with your Raleigh Orthopaedic physician for further guidance. 

Surgery – Arthroscopy

Surgery to fix a labral tear is known as arthroscopy. During the procedure, your Raleigh Orthopaedic surgeon  will use a thin, tube-shaped instrument with a lighted camera attached to the end. This instrument, called an arthroscope, is inserted through small incisions and used to assist your doctor in repairing the labrum. The arthroscopic surgery is often done on an outpatient basis, meaning the patient goes home the same day. Since this procedure is minimally-invasive, scarring and recovery time are shorter than with open surgery.
