Introduction The extracellular matrix (ECM) plays an integral role in wound healing. It provides both structure and growth factors that allow for the organised cell proliferation. Large or complex tissue defects may compromise host ECM, creating an environment that is unfavourable for the recovery of anatomical function and appearance. Acellular dermal matrices (ADMs) have been developed from a variety of sources, including human (HADM), porcine (PADM) and bovine (BADM), with multiple different processing protocols. The objective of this report is to provide an overview of current literature assessing the clinical utility of ADMs across a broad spectrum of applications. Methods PubMed, MEDLINE, EMBASE, Scopus, Cochrane and Web of Science were searched using keywords ‘acellular dermal matrix’, ‘acellular dermal matrices’ and brand names for commercially available ADMs. Our search was limited to English language articles published from 1999 to 2020 and focused on clinical data. Results A total of 2443 records underwent screening. After removing non-clinical studies and correspondence, 222 were assessed for eligibility. Of these, 170 were included in our synthesis of the literature. While the earliest ADMs were used in severe burn injuries, usage has expanded to a number of surgical subspecialties and procedures, including orthopaedic surgery (e.g. tendon and ligament reconstructions), otolaryngology, oral surgery (e.g. treating gingival recession), abdominal wall surgery (e.g. hernia repair), plastic surgery (e.g. breast reconstruction and penile augmentation), and chronic wounds (e.g. diabetic ulcers). Conclusion Our understanding of ADM’s clinical utility continues to evolve. More research is needed to determine which ADM has the best outcomes for each clinical scenario. Lay Summary Large or complex wounds present unique reconstructive and healing challenges. In normal healing, the extracellular matrix (ECM) provides both structural and growth factors that allow tissue to regenerate in an organised fashion to close the wound. In difficult or large soft-tissue defects, however, the ECM is often compromised. Acellular dermal matrix (ADM) products have been developed to mimic the benefits of host ECM, allowing for improved outcomes in a variety of clinical scenarios. This review summarises the current clinical evidence regarding commercially available ADMs in a wide variety of clinical contexts.
Sleep is important for our health and well-being and is especially pertinent to orthopedic surgery because it has been shown to play a role in pain tolerance. Knowing the benefits of sleep, one way to positively impact patients’ pain and recovery post-surgery is to encourage sleep. Zolpidem, a pharmacologic sleep aid, has been shown to decrease opioid consumption, reduce pain, and increase quality of life when briefly used after orthopedic procedures. Cognitive Behavioral Therapy for Insomnia (CBT-I), a nonpharmacologic sleep aid, has been shown to increase the quality of sleep and sleep time, decrease sleep onset latency, decrease pain, and help patients maintain those gains. Because of the dangers of opioids, it is important for physicians to search for alternative methods to manage their patients’ pain, like zolpidem and CBT-I. More research is needed to determine which method may be the most efficacious and how these can be integrated into patient care.
Background: A significant portion of the adults suffer from foot and ankle pain. The sex differences that exist throughout health care, pain management, and orthopedics may further complicate treatment strategies. The purpose of this study was to determine if there were any differences in women and men in health care seeking behavior and symptom chronicity in a West Texas orthopedic population with foot and ankle conditions. Materials and Methods: Data from 137 patients were collected in a retrospective chart review. Data were analyzed to determine if there were sex differences in time to primary care provider (PCP) after ankle injury, referral time from PCP to orthopedic surgeon consult, time from orthopedic consult to surgical intervention (if applicable), and chronicity of symptoms. Results: Women had a significantly higher percentage of chronic injuries than men (30.7% vs. 10.9%), but there were no sex differences in time to PCP from the time of injury, time from PCP visit to orthopedic consult, and time from orthopedic consult to surgical intervention. There were also no differences in those same time frames when compared by chronicity of symptoms (acute injury vs. chronic injury). Finally, we did not find any differences in pain scores between sexes or chronicity of symptoms. Conclusions: This study suggests that conventional health seeking sex differences may not apply to the foot and ankle patient population in West Texas and surrounding rural areas. Continuing to examine patterns in sex differences may lead to the development of more efficient and tailored treatment approaches and better outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
