Failed rotator cuff repairs present a complex issue for treating surgeons. Many methods of management exist for this pathology including revision repair with biologic augmentation, repairs with allograft, tendon transfers, superior capsular reconstruction, balloon arthroplasty, bursal acromial reconstruction, and reverse total shoulder arthroplasty. This review discusses the current literature associated with these management options.

Limiting cognitive resources negatively impacts motor learning, but its cognitive mechanism is still unclear. Previous studies failed to differentiate its effect on explicit (or cognitive) and implicit (or procedural) aspects of motor learning. Here, we designed a dual-task paradigm requiring participants to simultaneously perform a visual working memory task and a visuomotor rotation adaptation task to investigate how cognitive load differentially impacted explicit and implicit motor learning.

Introduction: During the healing process, the functional gradient attachment of the rotator cuff (RC) tendon-bone interface fails to regenerate, which severely impedes load transfer and stress dissipation, thereby increasing the risk of retears. As a result, the treatment of rotator cuff tears remains a significant clinical challenge.
Methods: In this study, a dual-crosslinked hyaluronic acid/polyethylene glycol (HA/PEG) hydrogel scaffold was synthesized using hyaluronic acid and polyethylene glycol as base materials.

This work introduces the novel anionic cluster BSiZn as the smallest molecular "compass", featuring a unique two-layered architecture with a planar pentacoordinate boron (ppB) center. The cluster comprises a quasi-planar BSi stator─a silicon-based analogue of borozene with σ/π double aromaticity (6π + 10σ delocalized electrons)─and a Zn rotor dimer. High-level calculations (CCSD(T)//PBE0-D3) reveal an ultralow rotational barrier of 0.

The treatment of shoulder dysplasia resulting from brachial plexus birth injury (BPBI) remains a matter of debate within pediatric orthopedic and neurosurgical communities. Various approaches have been proposed to address the muscular imbalance and joint incongruity that develop in affected children, with special attention paid to the roles of humeral head reduction and tendon transfers. : These procedures aim to correct the disproportionate strength between internal and external rotators of the shoulder.

Wilms' tumor is a common pediatric renal malignancy. In selected cases, nephron-sparing surgery (NSS) may be employed as part of the surgical approach. To prevent positive margins, optimal understanding of the tumor-kidney edge is essential.
