Abstract
BACKGROUND The purpose of this study was to identify preoperative factors associated with worse postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference (PI) scores 2 years after hand and wrist surgery. We hypothesized that older age, more comorbidities, increased substance use, and lower socioeconomic status would correlate with worse 2-year PROMIS PI scores. METHODS This study was a retrospective review of prospectively acquired data on 253 patients. Surveys were administered within 1 week of surgery and 2 years postoperatively. Bivariate and multivariable analyses were conducted to identify significant predictors of worse 2-year PROMIS PI scores and change in PROMIS PI scores. RESULTS Older age, higher body mass index, more comorbidities, lower preoperative expectations, more prior surgeries, unemployment, smoking, higher American Society of Anesthesiologists (ASA) score, and multiple other socio-demographic factors were correlated with worse 2-year PROMIS PI scores (P ≤ .018). Similar factors were also correlated with less improvement in 2-year PROMIS PI scores (P ≤ .048). Worse scores on all preoperative patient-reported outcome measures correlated with worse 2-year PROMIS PI scores (P ≤ .007). Multivariable analysis identified smoking history, less frequent alcohol consumption, worse preoperative PROMIS social satisfaction and Numeric Pain Scale whole body scores, and higher ASA scores as independent predictors of worse 2-year PROMIS PI. The same factors in addition to better baseline PROMIS PI were predictive of less improvement in 2-year PROMIS PI. CONCLUSION Numerous preoperative factors were predictive of worse postoperative 2-year PROMIS PI and less improvement in 2-year PROMIS PI for patients undergoing hand and wrist surgery.

Abstract
Traumatic spinal cord injury (TSCI) is a debilitating condition that can have significant effects on physical function and overall quality of life. Mechanisms of injury can vary from major trauma to low-energy falls. There has been a recent increase in the number of elderly patients with TSCI. A retrospective analysis of population-based hospital records linked with health care administrative datasets was conducted to measure age-standardized rates of TSCI over time. The study was conducted to describe the epidemiology and demographic characteristics of patients who experienced TSCI between 2001 and 2021 in the province of British Columbia, Canada. Demographic, clinical characteristics, and rates of TSCI were evaluated over time. Linear regression was used to assess changes over time. The study identified 3622 patients with TSCI. The average age at the time of injury was 51.1 (standard deviation [SD] 21.19) and 75.0% were males. The average annual age-standardized rate in this population was 35.4 per million. The overall rate remained stable throughout the study period. The mean age at injury increased from 41.9 to 57.5 over the study period of 2001-2021 (p < 0.001). The most frequent causes of injury were low-energy falls (49.9%) and motor vehicle injuries (36.6%). The proportion of injuries related to falls increased over the study period (p < 0.001). Motor and sensory complete TSCI were seen in higher rates among younger patients, and cervical spine injuries were most common among all age-groups. The rate of TCSI was consistent during the study period, though the demographic of patients and their injury mechanism changed considerably; elderly low-energy falls were an increasing proportion of cases. Continued vigilance in elderly fall prevention is needed to reduce the incidence of TCSI among the elderly.

Abstract
INTRODUCTION Hand injuries constitute up to 30% of the total cases treated in emergency departments. Over time, demographic changes, especially an aging population, and shifts in workplace safety regulations and healthcare policies have significantly impacted the landscape of hand trauma. This study aims to identify and analyze these evolving trends over nearly two decades. METHODS In this retrospective, cross-sectional study, we investigated patients who were admitted to the high-volume regional hand trauma center of a university hospital between January 2007 and December 2022. We analyzed trends in patients' demographics and annual alterations of injuries. For the comparative analysis, patients were divided into two groups based on the time of presentation: the early cohort (2007-2014) and the current cohort (2015-2022). RESULTS A total of 14,414 patients were admitted to our emergency department within the study period. A significant annual increase in patient age was identified (R2 = 0.254, p = 0.047). The number of presentations increased annually by an average of 2% (p < 0.001). The incidence of the following hand injuries significantly increased: sprains/strains (+ 70.51%, p = 0.004), superficial lacerations (+ 53.99%, p < 0.001), joint dislocations (+ 51.28%, p < 0.001), fractures (carpal: + 49.25%, p = 0.003; noncarpal: + 39.18%, p < 0.001), deep lacerations (+ 37.16%, p < 0.001) and burns and corrosions (+ 29.45%, p < 0.001). However, rates of amputations decreased significantly (- 22.09%, p = 0.04). CONCLUSIONS A consistent and significant annual increase in both the total number of injuries and the average age of patients was identified. An aging population may increase injury rates and comorbidities, stressing healthcare resources. Our study underscores the need to adapt healthcare structures and reimbursement policies, especially for outpatient hand injury care.

Abstract
BACKGROUND The forearm/wrist squeeze/compression test has been used to examine digital flexor tendon injuries with varied names. Furthermore, the test has not been minutely described and its mechanism remains unclear. We renamed the test the "distal forearm squeeze test". The purpose of this study was to elaborate on the test and elucidate the mechanism. METHODS Two patients with digital flexor tendons ruptured in zone 3 and zone 1 respectively and 50 outpatients with intact digital tendons underwent the test. Then the test was performed on 3 chickens under 4 conditions. First, when the digital flexor and extensor tendons were all intact. Second, after the flexor tendons of the third toe were transected. Third, after the flexor tendons of all toes of the foot were transected. Finally, after the flexor and extensor tendons of all toes of the foot were transected. RESULTS In the patient with digital flexor tendons ruptured in zone 3, the test showed that the injured digit was flexed slightly while the uninjured digits were flexed obviously. In the patient with digital flexor tendon ruptured in zone 1, after separate stabilization of the proximal interphalangeal (PIP) joints of the injured and uninjured fingers in extension, the test showed that the distal interphalangeal joint of the patient's injured finger had no response, while those of the uninjured fingers were flexed. All 50 subjects showed clenched or half-clenched hands in response to the test. The test showed that all toes were flexed when the digital tendons of the chicken were intact. All toes were flexed except the third toe after the flexor tendons of the third toe were transected. All toes were extended after all the digital flexor tendons were transected. All toes had no response after all the digital flexor and extensor tendons were transected. CONCLUSIONS The distal forearm squeeze test is valuable in examining digital flexor tendon injuries. If only the flexor digitorum profundus tendon is examined, the PIP joint of the finger should be stabilized in extension during the test.

Abstract
The prevalence of hand injuries increases with age, with elderly patients being more prone to hand lesions due to a combination of factors, such as reduced bone density and muscle strength, impaired sensation, and cognitive impairment. Despite the high incidence of hand injuries in the elderly population, few studies have addressed the management and outcomes of hand lesions in this age group. This study aimed to analyze the characteristics and management of hand lesions in patients over 80 years old. The authors conducted a retrospective analysis of medical records of patients over 80 years old who reached their Emergency Department with hand lesions between 2001 and 2020. Data on demographics, injury characteristics, and management were collected and analyzed. A total of 991 patients with hand lesions were included in the study, with a mean age of 84.9 years. The most common causes of injuries were domestic accidents (32.6%) and traffic accidents (12.8%). The most frequent types of hand lesions were fractures (23.5%) and superficial wounds (20.5%). Overall, 23.4% underwent surgical treatment for their hand issue, and 22.1% had associated injuries, among which, the most common were head trauma and other bone fractures. In conclusion, hand lesions in patients over 80 years old are frequent and pose significant challenges in diagnosis and management. Particular attention should be paid to associated injuries and limit indications to surgery when strictly necessary.

Abstract
PURPOSE To describe the principles, process, and results of creating the International Consortium for Health Outcomes Measurement (ICHOM) standard set for hand and wrist conditions. METHODS Following the standardized methods of ICHOM, an international working group of hand surgeons, therapists, and researchers was assembled to develop an evidence-based, patient-centered, standard set of outcome measures for patients with hand and wrist conditions. Multiple systematic reviews were performed to support our choices of outcome domains and tools for hand and wrist conditions. Fourteen video conferences were held between March 2018 and March 2020, and a modified Delphi process was used. RESULTS A consensus was reached on 5 measurement tracks: the thumb, finger, wrist, nerve, and severe hand trauma tracks, with a distinction between regular and extended tracks for which specific allocation criteria applied. The standard set contains a selection of outcome tools and predefined time points for outcome measurement. Additionally, we developed a hierarchy for using the tracks when there are multiple conditions, and we selected risk-adjustment, case-mix variables. CONCLUSIONS The global implementation of the ICHOM standard set for hand and wrist conditions may facilitate value-based health care for patients with hand and wrist conditions. CLINICAL RELEVANCE The ICHOM standard set for hand and wrist conditions can enable clinical decision making, quality improvement, and comparisons between treatments and health care professionals.

Abstract
We studied the efficacy of using mesenchymal stem cells (MSC) and a polymeric compound (based on chitosan and cellulose with integrated cerium dioxide nanoparticles (PCCD)) in wound healing, and to compare the effects with various invasive and external drugs used for the same purpose. Two wounds were made on the backs of each of 112 Wistar rats, removing the skin. Eight groups were studied: Control_0—intact wounds; Control_ss—0.9% NaCl injections; MSC injections; Control_msc—intact wounds on the opposite side of the body from the MSC group; external application of the PCCD; external application of a combination of the drugs PCCD + MSC; DCh –ointment Dioxomethyltetrahydropyrimidine + Chloramphenicol; and DHCB—injections of a deproteinized hemoderivative of calf blood. After 14 days, we evaluated the state and size of the wounds, studied the level of microcirculation, performed a histological study, and identified and counted the different types of cells. The most effective remedy was combination PCCD + MSC. The treatments in the PCCD and MSC groups were more effective than in the DHCB and DCh groups. Invasive drugs and DCh slowed the regeneration process. DHCB did not affect the rate of healing for acute wounds without ischemia during the first week. The proven efficacy of developed polymeric compounds demonstrates the feasibility of further studies in clinical practice.

Abstract
Background: Elderly people with severe finger weakness may need assistive health technology interventions. Finger weakness impedes the elderly in executing activities of daily living such as unbuttoning shirts and opening clothes pegs. While studies have related finger weakness with ageing effects, there appears to be no research that uses an algorithmic problem-solving approach such as the theory of inventive problem-solving (TRIZ) to recommend finger grip assistive technologies that resolve the issue of finger weakness among the elderly. Using TRIZ, this study aims to conceptualise finger grip enhancer designs for elderly people. Methods: Several TRIZ tools such as the cause-and-effect chain (CEC) analysis, engineering contradiction, physical contradiction, and substance-field analysis are used to conceptualise solutions that assist elderly people in their day-to-day pinching activities. Results: Based on the segmentation principle, a finger assistant concept powered by a miniature linear actuator is recommended. Specific product development processes are used to further conceptualise the actuation system. The study concluded that the chosen concept should use a DC motor to actuate fingers through tendon cables triggered by a push start button. Conclusions: Finger pinch degradation worsens the quality of life of the elderly. A finger grip enhancer that assists in day-to-day activities may be an effective option for elderly people, not only for their physical but also their mental well-being in society.

Abstract
High-quality and aesthetic wound healing, as well as effective medical support of this process, continue to be relevant. This study aims to evaluate the medical efficacy of a novel smart polymeric nanodrug (SPN) on the rate and mechanism of wound healing in experimental animals. The study was carried out in male Wistar rats (aged 8-9 months). In these animals, identical square wounds down to the fascia were made in non-sterile conditions on the back on both sides of the vertebra. SPN was used for the treatment of one wound, and the other wound was left without treatment (control group). Biocompatible citrate-stabilized cerium oxide nanoparticles integrated into a polysaccharide hydrogel matrix containing natural and synthetic polysaccharide polymers (pectin, alginate, chitosan, agar-agar, water-soluble cellulose derivatives) were used as the therapeutic agent. Changes in the wound sizes (area, volume) over time and wound temperature were assessed on Days 0, 1, 3, 5, 7, and 14. Histological examination of the wounds was performed on Days 3, 7, and 14. The study showed that the use of SPN accelerated wound healing in comparison with control wounds by inhibiting the inflammatory response, which was measured by a decreased number of white blood cells in SPN-treated wounds. It also accelerated the development of fibroblasts, with an early onset of new collagen synthesis, which eventually led to the formation of more tender postoperative scars. Thus, the study demonstrated that the use of SPN for the treatment of wounds was effective and promising.

Abstract
Bone lesions are an important public health problem, with high socioeconomic costs. Bone tissue repair is coordinated by an inflammatory dynamic process mediated by osteoprogenitor cells of the periosteum and endosteum, responsible for the formation of a new bone matrix. Studies using antioxidant products from plants for bone lesion treatment have been growing worldwide. We developed a systematic review to compile the results of works with animal models investigating the anti-inflammatory activity of plant extracts in the treatment of bone lesions and analyze the methodological quality of the studies on this subject. Studies were selected in the PubMed/MEDLINE, Scopus, and Web of Science databases according to the PRISMA statement. The research filters were constructed using three parameters: animal model, bone repair, and plant extracts. 31 full-text articles were recovered from 10 countries. Phytochemical prospecting was reported in 15 studies (48.39%). The most common secondary metabolites were flavonoids, cited in 32.26% studies (n = 10). Essential criteria to in vivo animal studies were frequently underreported, suggesting publication bias. The animals treated with plant extracts presented positive results in the osteoblastic proliferation, and consequently, this treatment accelerated osteogenic differentiation and bone callus formation, as well as bone fracture repair. Possibly, these results are associated with antioxidant, regenerative, and anti-inflammatory power of the extracts. The absence or incomplete characterization of the animal models, treatment protocols, and phytochemical and toxicity analyses impairs the internal validity of the evidence, making it difficult to determine the effectiveness and safety of plant-derived products in bone repair.

Abstract
INTRODUCTION It is accepted that the incidence of fractures in patients aged ≥ 65 years is increasing but little is known about which fractures are becoming more common in this group of patients. Virtually all research has concentrated on the classic fragility fractures of the proximal femur, proximal humerus, pelvis, spine and distal radius but it is likely that other fractures are becoming more common. METHODS We have examined two prospectively collected databases 10 years apart to see which fractures are becoming more common in ≥ 65 year old patients. We compared the fractures to look for epidemiological differences over the 10-year period and we compared the epidemiology of the fractures that had increased in incidence with equivalent fractures in the < 65 year old population. RESULTS Analysis shows that in older female patients fractures of the clavicle, finger phalanges, ankle and metatarsus are increasing in incidence. In males there is an increasing incidence of fractures of the proximal humerus, distal humerus, metacarpus, pelvis, femoral diaphysis, distal tibia and ankle. In females the basic epidemiology of fractures in the ≥ 65 year old population was very similar to the fractures seen in younger females and we believe that the increasing incidence of fractures in the future will mainly be low velocity fractures following falls. In older males however, it is apparent that there is a much wider variation in the causes of fracture. DISCUSSION We believe that the changes in fracture epidemiology in older patients relate to improved health and longevity and analysis of our population during the study period shows significant social changes which are associated with increased longevity and improved health. It is probable that fractures in older patients will continue to increase in incidence and that other fractures that are now commonly seen in middle-aged patients will be seen in older patients. Surgeons will have to treat more complex fractures in older males than in older females and it is likely that there will be a higher incidence of open and multiple fractures. Appropriate management techniques will need to be established.
