Article Abstract
Tissue engineering has demonstrated its efficacy in promoting tissue regeneration, and extensive research has explored its application in rotator cuff (RC) tears. However, there remains a paucity of research translating from bench to clinic. A key challenge in RC repair is the healing of tendon-bone interface (TBI), for which bioactive materials suitable for interface repair are still lacking. The umbilical cord (UC), which serves as a vital repository of bioactive components in nature, is emerging as an important source of tissue engineering materials. A minimally manipulated approach is used to fabricate UC scaffolds that retain a wealth of bioactive components and cytokines. The scaffold demonstrates the ability to modulate the TBI healing microenvironment by facilitating cell proliferation, migration, suppressing inflammation, and inducing chondrogenic differentiation. This foundation sets the stage for in vivo validation and clinical translation. Following implantation of UC scaffolds in the canine model, comprehensive assessments, including MRI and histological analysis confirm their efficacy in inducing TBI reconstruction. Encouraging short-term clinical results further suggest the ability of UC scaffolds to effectively enhance RC repair. This investigation explores the mechanisms underlying the promotion of TBI repair by UC scaffolds, providing key insights for clinical application and translational research.

Technical note: reduction of a posteriorly dislocated humeral head via the anterior deltopectoral approach in a posterior fracture dislocation of the proximal humerus.

We aim to describe an approach for reducing the posteriorly dislocated humeral head through the rotator interval via a deltopectoral approach that is frequently utilized for internal fixation of proximal humerus fractures and fracture dislocations. The sheath of the long head of biceps (LHB) and the rotator interval capsule are opened till the glenoid; this enables access to the glenohumeral joint via the rotator interval. A long-handle Cobb elevator is introduced through the rotator interval and, under intraoperative imaging, advanced posteromedially to the dislocated humeral head.

This minimum standard aids comparisons across the literature and helps to ensure methodological rigor. However, in some situations these minimum durations are not required to answer specific research questions and strictly enforcing these requirements poses unnecessary barriers to research by adding cost and complexity, increasing the risk of loss to follow-up, and potentially restricting early dissemination of clinically important findings.

Introduction: Reverse total shoulder arthroplasty is a well-established treatment for patients with rotator cuff tear arthropathy. The outcome after reverse total shoulder arthroplasty has been investigated in several studies and national registries. However, the treatment has not been compared to non-surgical treatment.

Rotator cuff tendinopathy is a common cause of shoulder pain and dysfunction, presenting in two primary forms: calcific and non-calcific. These subtypes differ significantly in their pathophysiology, clinical manifestations, and natural history, necessitating tailored diagnostic and therapeutic approaches. This review delineates the clinical presentations of calcific rotator cuff tendinopathy (RCCT), characterized by distinct pre-calcific, calcific, and post-calcific stages, and contrasts them with the more insidious, degenerative course of non-calcific rotator cuff tendinopathy.

Methods: This systematic review was conducted in accordance to PRISMA guidelines and was registered in PROSPERO (CRD4202461663). A comprehensive search was done in the following databases MEDLINE, Web of Science, Google Scholar.
