Shoulder Instability

Dr. Garcia demonstrates his advanced technique for 360 degree labral repairs

Shoulder instability is a chronic condition that causes frequent dislocations of the shoulder joint.


 A dislocation occurs when the end of the humerus (the ball portion) partially or completely dislocates from the glenoid (the socket portion) of the shoulder. A partial dislocation is referred to as a subluxation whereas a complete separation is referred to as a dislocation.

Risk Factors

The risk factors that increase the chances of developing shoulder instability include:

OSS Shoulder Dislocation and Labral Tears

  • Injury or trauma to the shoulder
  • Falling on an outstretched hand
  • Repetitive overhead sports such as baseball, swimming, volleyball, or weightlifting
  • Loose shoulder ligaments or an enlarged capsule


The common symptoms of shoulder instability include pain with certain movements of the shoulder; popping or grinding sound may be heard or felt, swelling and bruising of the shoulder may be seen immediately following subluxation or dislocation. Visible deformity and loss of function of the shoulder occurs after subluxation or sensation changes such as numbness or even partial paralysis can occur below the dislocation because of pressure on nerves and blood vessels.

Conservative Treatment

The goal of conservative treatment for shoulder instability is to restore stability, strength, and full range of motion. Conservative treatment measures may include the following:

Dr. Garcia demonstrates his arthroscopic surgical technique for anterior labrum “Bankart” repair.

  • Closed Reduction: Following a dislocation, your surgeon can often manipulate the shoulder joint, usually under anesthesia, realigning it into proper position. Surgery may be necessary to restore normal function depending on your situation
  • Medications: Over the counter pain medications and NSAID’s can help reduce the pain and swelling. Steroidal injections may also be administered to decrease swelling
  • Rest: Rest the injured shoulder and avoid activities that require overhead motion. A sling may be worn for 2 weeks to facilitate healing
  • Ice: Ice packs should be applied to the affected area for 20 minutes every hour

Dr. Garcia demonstrates his new technique for the Latarjet procedure.


When the conservative treatment options fail to relieve shoulder instability, your surgeon may recommend shoulder stabilization surgery. Shoulder stabilization surgery is done to improve stability and function to the shoulder joint and prevent recurrent dislocations. It can be performed arthroscopically, depending on your situation, with much smaller incisions. Arthroscopy is a surgical procedure in which an arthroscope, a small flexible tube with a light and video camera at the end, is inserted into a joint to evaluate and treat of the condition. The benefits of arthroscopy compared to the alternative, open shoulder surgery are smaller incisions, minimal soft tissue trauma, less pain leading to faster recovery.

Biomechanical Analysis of Plate Fixation Compared With Various Screw Configurations for Use in the Latarjet Procedure

PURPOSE: To determine the biomechanical properties of miniplate fixation for the Latarjet procedure compared with various screw fixation configurations.

Remplissage for Anterior Shoulder Instability with Hill-Sachs Lesions - A Systematic Review & Meta-Analysis

BACKGROUND: The purpose of this study is to systematically review and meta-analyze the current evidence in the literature to determine how arthroscopic Bankart repair (ABR) and Remplissage compare to arthroscopic Bankart repair alone and the open Latarjet procedure for anterior shoulder instability in patients with a concomitant Hill-Sachs lesions.
