What is the clinical importance of radiographic changes around the humeral component in anatomic shoulder arthroplasty? A minimum 4-year follow-up study.
J Shoulder Elbow Surg
January 2025
Investigation Performed at the University of Washington, Department of Orthopaedic Surgery and Sports Medicine, Seattle, WA, USA. Electronic address:
Background: While stress shielding and adaptive bone changes around the humeral component are often observed after shoulder arthroplasty, the potential causative factors and clinical significance of these findings at mid-term follow-up have not been well elucidated. The purpose of this study was to investigate the frequency, patterns and clinical significance of radiographic findings around the humeral component of total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) at minimum 4-year follow-up.
Methods: The 6-week and minimum 4-year radiographs of patients who underwent HA and TSA were evaluated for filling ratios, changes in the humeral bone surrounding the component, and component shift or subsidence.
Stress shielding in reverse shoulder arthroplasty using a proximally coated stem for proximal humeral fractures: Does it have clinical relevance?
Shoulder Elbow
January 2025
Orthopaedic and Trauma Surgery Department, Hospital de Terrassa, Terrassa, Barcelona, Spain.
Objectives: To evaluate the clinical significance of stress shielding in patients who have undergone an uncemented reverse shoulder arthroplasty (RSA) with a proximally coated stem for complex proximal humeral fractures (PHF) comprising 3 or 4 parts, assessed at 2 years postoperatively. Additionally, this study aims to examine the correlation between tuberosity healing and clinical outcomes.
Methods: Single Centre.
A new classification for dislocated and displaced proximal humeral fractures.
J Orthop Surg Res
January 2025
Department of Orthopaedic Surgery, Kobe City Medical Center General Hospital, 2-1-1 Minatojima-minamimachi, Chuo-ku, Kobe, 650-0047, Japan.
Background: Although the Neer and AO/OTA classifications have been widely accepted, observer reliability studies of these two classifications have questioned their reliability and reproducibility to date. We developed an entirely new classification, the Mitsuzawa classification, for dislocated and displaced proximal humeral fractures and tested all three classifications for their intra- and interobserver reliability.
Methods: Two experienced shoulder surgeons and two orthopedic residents independently evaluated the Xray (xR) values of 100 proximal humeral fractures (PHFs).
Clinical Presentation and Integrated Management of Pressure Injuries in the Emergency Hospital Setting: A Plastic Surgeon's Perspective.
Healthcare (Basel)
December 2024
Department 11, Discipline Plastic and Reconstructive Surgery, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania.
: Pressure injuries are localized areas of tissue damage or necrosis that occur when pressure is applied to the skin for prolonged periods, often over bony prominences, often the sacrum, heels, ischial tuberosities, and greater trochanters. The pathophysiology is complex, involving a combination of mechanical forces, ischemia, and tissue hypoxia. : We conducted a 2-year retrospective study aiming to assess the clinical characteristics, risk factors, and management of pressure injuries in patients admitted to an emergency hospital who underwent a plastic surgery examination.
