Arthroscopic Removal of Loose Glenoid Component in Anatomic Total Shoulder Arthroplasty.

Aseptic glenoid component loosening after anatomic total shoulder arthroplasty remains an important cause of late clinical failure and revision surgery. We present here the surgical technique of all-arthroscopic removal and glenoid bone grafting. Arthroscopic removal of a loose glenoid component and bone grafting of the glenoid defect without dermal allograft preserves glenoid bone stock and obviates the need for multiple suture anchors to hold the graft in place.

Association of Geographic Distance and Hospital Characteristics With Use of Interhospital Transfer by Air: A Multicenter Retrospective Study.

Objective: Interhospital transfer by air (IHTA) represents the majority of helicopter air ambulance transports in the United States, but the evaluation of what factors are associated with utilization has been limited. We aimed to assess the association of geographic distance and hospital characteristics (including patient volume) with the use of IHTA.

Methods: This was a multicenter, retrospective study of helicopter flight request data from 2018 provided by a convenience sample of 4 critical care transport medicine programs in 3 US census regions.
