Glenoid Component Failure After Total Shoulder Arthroplasty With Migration of the Component Into Posterior Subcutaneous Tissue: A Case Report
$25.00
Glenoid component loosening is the most frequently cited complication related to total shoulder arthroplasty (TSA). The mechanism behind glenoid loosening remains an area of active investigation. Distant migration of the implant following loosening has not been described. Both glenoid implant removal and revision have demonstrated successful results following symptomatic loosening. This report presents the case of a 61-year-old female who experienced a complete glenoid component dissociation following TSA with migration of the implant into the subcutaneous tissue of the posterior shoulder. The patient underwent implant removal without glenoid revision and has experienced an excellent outcome at midterm follow-up. Although glenoid component loosening remains the most common complication associated with TSA, this particular scenario and the subsequent management have not been previously reported.
