Reverse dynamisation: a modern perspective on Stephan Perren's strain theory.

Eur Cell Mater 2021 Jun 10;41:668-679. Epub 2021 Jun 10.

Department of Orthopedic Surgery, University of Texas Health Science Centre San Antonio, 7703 Floyd Curl Drive, MC 7774, San Antonio, TX 78229-3900,

The present review acknowledges the tremendous impact of Stephan Perren's strain theory, considered with respect to the earlier contributions of Roux and Pauwels. Then, it provides further insight by examining how the concept of reverse dynamisation extended Perren's theory within a modern context. A key factor of this more contemporary theory is that it introduces variable mechanical conditions at different time points during bone healing, opening the possibility of manipulating biology through mechanics to achieve the desired clinical outcome.

Recent advances in the development of nitric oxide-releasing biomaterials and their application potentials in chronic wound healing.

J Mater Chem B 2021 Jun 10. Epub 2021 Jun 10.

Department of Histology and Embryology, NMPA Key Laboratory for Safety Evaluation of Cosmetics, School of Basic Medical Sciences, Guangdong Provincial Key Laboratory of Bone and Joint Degeneration Diseases, The Third Affiliated Hospital of Southern Medical University, Southern Medical University, Guangzhou, China.

Chronic wounds, such as pressure ulcers, vascular ulcers and diabetic foot ulcers (DFUs), often stay in a state of pathological inflammation and suffer from persistent infection, excess inflammation, and hypoxia, thus they are difficult to be healed. Nitric oxide (NO) plays a critical role in the regulation of various wound healing processes, including inflammatory response, cell proliferation, collagen formation, antimicrobial action and angiogenesis. The important role of NO in wound healing attracts intensive research focus on NO-based wound healing therapy. Read More

Monocyte and macrophage derived myofibroblasts: Is it fate? A review of the current evidence.

Wound Repair Regen 2021 Jun 9. Epub 2021 Jun 9.

Department of Medicine, McMaster University and The Research Institute of St. Joe's Hamilton, Firestone Institute for Respiratory Health, Hamilton, Ontario, Canada.

Since the discovery of the myofibroblast over 50 years ago, much has been learned about its role in wound healing and fibrosis. Its origin, however, remains controversial, with a number of progenitor cells being proposed. Macrophage-myofibroblast transition (MMT) is a recent term coined in 2014 that describes the mechanism through which macrophages, derived from circulating monocytes originating in the bone marrow, transformed into myofibroblasts and contributed to kidney fibrosis.

J Appl Oral Sci 2021 4;29:e20200932. Epub 2021 Jun 4.

Campania University Luigi Vanvitelli, Multidisciplinary Department of Medical, Surgical and Dental sciences, Naples, Italy.

Third molar removal surgery usually comes accompanied by postoperative discomfort, which could be influenced by the surgical approach chosen. This scoping systematic review aimed at compiling the available evidence focused on the influence of flap design, including envelope flap (EF), triangular flap (TF), and modified triangular flap (MTF), on postoperative pain, swelling, and trismus, as primary outcome measures, and any result mentioning healing promotion or delay, as secondary outcome measure, after mandibular third molar extraction surgery. An electronic search, complemented by a manual search, of articles published from 1999 to 2020 was conducted in the Medline (PubMed), EMBASE and Web of Science databases including human randomized controlled trials, prospective, and retrospective studies with at least 15 patients.

Spatiotemporal Immunomodulation Using Biomimetic Scaffold Promotes Endochondral Ossification-Mediated Bone Healing.

Adv Sci (Weinh) 2021 06 16;8(11):e2100143. Epub 2021 Mar 16.

Key Laboratory for Ultrafine Materials of Ministry of Education, School of Materials Science and Engineering, and Engineering Research Center for Biomedical Materials of Ministry of Education, East China University of Science and Technology, Shanghai, 200237, P. R. China.

Biomaterials play an important role in treating bone defects by promoting direct osteogenic healing through intramembranous ossification (IO). However, majority of the body's bones form via cartilaginous intermediates by endochondral ossification (EO), a process that has not been well mimicked by engineered scaffolds, thus limiting their clinical utility in treating large segmental bone defects. Here, by entrapping corticosteroid dexamethasone within biomimetic recombinant human bone morphogenetic protein (rhBMP)-loaded porous mesoporous bioglass scaffolds and regulating their release kinetics, significant degree of ectopic bone formation through endochondral ossification is achieved.

Engaging a polylactide copolymer in oral tissue regeneration: first validation of Suprathel for guided epithelial and osseous healing.

J Med Life 2021 Mar-Apr;14(2):181-197

Department of Maxillofacial Surgery and Radiology, Division of Maxillofacial Surgery and Implantology, Iuliu Hatieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania.

The present study investigated the capacity of Suprathel (a copolymer membrane, so far validated for skin regeneration) to also regenerate oral tissue - mucosa and bone, by comparing this biomaterial, in a split-mouth rabbit model, to Mucoderm, a xenogeneic collagen matrix certified for keratinized oral mucosa healing. The clinical reason behind this experimental animal model was to determine whether the benefits of this advanced skin regeneration product (Suprathel) could be conveyed for future evaluation in clinical trials of oral tissue regeneration in humans. The outcomes of this study validated the use of Suprathel, a terpolymer of polylactide with trimethylene carbonate and ε-caprolactone, for stimulation of oral epithelium and alveolar bone regeneration in rabbits.

Healing of a large avulsed mandibular bony segment: report of a unique case.

Int J Oral Maxillofac Surg 2021 Jun 5. Epub 2021 Jun 5.

Department of Oral and Maxillofacial Surgery, King Edward Medical University/Mayo Hospital, Lahore, Pakistan.

This case report puts an emphasis on retaining and re-fixing any avulsed bony segments in the maxillofacial region and maintaining the periosteal layer whenever possible, especially in young patients. Adequate bony fixation and watertight soft tissue closure are vital components for bone healing. The healing potential of facial bones is much higher as compared to the long bones, due to the superior blood supply. Read More
