Factors Influencing Stem Subsidence in 135-Degree Inlay Reverse Shoulder Arthroplasty Open
Background/Objectives: Reverse shoulder arthroplasty (RSA) using a 135-degree inlay-type humeral stem has recently gained popularity due to its bone-preserving design. However, stem subsidence (hereafter, subsidence) and its contributing f…

Prevalence and risk factors for stem subsidence following reverse shoulder arthroplasty using on-lay press-fit short stems Open
Introduction: In reverse shoulder arthroplasty (RSA), press-fit short stems offer benefits such as reduced operative time and bone preservation. However, stem subsidence has been reported, although the risk factors remain unclear. This stu…

Bilateral Reverse Total Shoulder Arthroplasty for Bilateral Proximal Humeral Fractures Complicated by Periprosthetic Fractures Open
Reverse shoulder arthroplasty (RSA) is being increasingly employed for complex proximal humeral fractures (PHFs) in older patients, particularly in cases with severe osteoporosis. However, bilateral PHFs and subsequent periprosthetic fract…

Impact of prior arthroscopic rotator cuff repair on postoperative outcomes of reverse shoulder arthroplasty: a comparative analysis of muscle strength recovery and clinical results Open
Postoperative muscle strength improvement was not observed in patients undergoing rTSA with a history of ARCR, and their postoperative clinical outcomes were inferior to those undergoing rTSA without a history of ARCR. This deficiency in m…

In vivo study on the repair of rat Achilles tendon injury treated with non-thermal atmospheric-pressure helium microplasma jet Open
Non-thermal atmospheric-pressure plasma (NTAPP) has been widely studied for clinical applications, e.g., disinfection, wound healing, cancer therapy, hemostasis, and bone regeneration. It is being revealed that the physical and chemical ac…

Bone mineral density around cementless short stems after reverse shoulder arthroplasty: changes over time and its relationship to stem positioning Open
In reverse shoulder arthroplasty cementless short stems, changes that that occurred between postoperative year 1 to year 2 demonstrated a decrease in BMD in zone 3. In addition, a decrease in BMD in zone 1 was observed with a stem alignmen…

Reliability and validity of a new deltoid muscle area measurement method after reverse shoulder arthroplasty Open
DA measurement in the middle part of the deltoid's total length after RSA was not affected by metal artifacts and had excellent reproducibility. This measurement method positively correlated with postoperative muscle strength, suggesting i…

Assessment of Prevalence and Risk Factors for Central Sensitization Related to Shoulder Osteoarthritis and Rotator Cuff Tears Using the Central Sensitization Inventory: A Cross-Sectional Study in Shoulder Surgery Patients Open
Shoulder disorders occasionally cause intractable pain. Central sensitization (CS) may be involved in such pain. Identifying risk factors associated with CS is crucial for effective pain control. This study aimed to determine the effects o…
