Demographic shifts reshaping the landscape of hand trauma: a comprehensive single-center analysis of changing trends in hand injuries from 2007 to 2022.

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.

Free Tissue Transfer for Reconstruction After Bilateral Skin Sparing Mastectomy-A Systematic Review.

BACKGROUND: Breast cancer is the most commonly diagnosed malignant neoplasia in females worldwide. Overall survival and patients' choice for bilateral mastectomy have increased. It is therefore important to offer breast reconstructive procedures to improve patient quality of life and self-esteem. The aim of this systematic literature review is to quantify the outcome and sustainability of bilateral breast reconstruction using autologous, vascularized free tissue transfer. METHODS: A systematic literature review of PubMed, Cochrane, and the Web of Science databases was performed. A total of 5879 citations were identified, and 12 studies met the inclusion criteria. RESULTS: A total of 1316 patients were included, with a mean age of 47.2 years. Overall, 32.5% of patients experienced a complication after breast reconstruction. If reported, 7.45% of patients experienced major complications, while 20.7% had minor complications.The following flaps were used for breast reconstruction, in order of reducing frequency: DIEP (45.45%), TRAM (22.73%), SIEA (9.09%), SGAP (9.09%), TUG (4.55%), TMG (4.55%), and LD/MLD (4.55%). CONCLUSIONS: Current studies indicate that bilateral breast reconstruction using autologous, vascularized free tissue transfer is a safe procedure for postmastectomy reconstruction and offers stable long-term results. This is particularly in comparison to implant-based breast reconstruction.

Blood Vessel Injuries of the Fingers: A Clinical Comparison of One- and Two-Arterial Blood Supply.

Traumatic finger injuries are very common in emergency medicine. When patients present with finger injuries, there is often damage to the vascular nerve bundles, which requires subsequent reconstruction. It is unknown if repairing a unilaterally injured artery affects patients' recovery in a well-perfused finger. This retrospective cohort study compares the clinical outcomes of 11 patients with one-vessel supply (mean age 48.3 years; 7 males, 4 females) to 14 patients with two-vessel supply (mean age 44.5 years; 8 males, 6 females). The patient outcomes were assessed using patient questionnaires (Disabilities of Arm, Shoulder, and Hand (DASH), European Quality of Life 5 Dimensions 5 Level Version (EQ-5D-5L), and EuroQol visual analog scale (EQ-VAS)) and a clinical examination of hand function and imaging of circulatory efficiency. No significant changes were observed in the DASH, EQ-5D-5L, and EQ-VAS questionnaires. Clinical evaluation of hand function, measured by cold sensitivity, two-point discrimination, pain numerical analog scale, and grip strength also revealed no significant differences between cohorts. Blood flow measurements using thermal imaging revealed no effects on circulation in the affected digit. Collectively, the study finds reconstruction is not absolutely necessary when there is one intact digital artery as it is sufficient for healing and functional outcomes. We recommend finger artery reconstruction when both digital arteries are injured or if an immediate tension-free suture is possible.

Factor XIII: More than just a fibrin stabilizer for the burn patient? A matched-pair analysis.

Background: Acquired factor XIII deficiency is an underestimated risk in patients with large surface burns, which potentially exposes these patients to prolonged bleeding and delayed wound healing if undetected. Methods: A retrospective matched-pair analysis of the burn registry of the Department of Plastic, Aesthetic, Hand, and Reconstructive Surgery of Hannover Medical School was performed from 2018 to 2023. Results: A total of 18 patients were included. Acquired factor XIII deficiency was not statistically significant correlated with age, sex, or body mass index. Patients who developed acquired factor XIII deficiency had a significantly longer hospital stay (72.8 days) compared with those in the matched group (46.4 days), although burn depths, total body surface area, and Abbreviated Burn Severity Index were not statistically correlated with factor XIII deficiency. Conclusions: Little is known about acquired factor XIII deficiency in patients with burns. Factor XIII supplementation may improve hemostasis, wound healing, and general outcome while reducing the patient's exposure to blood products.

Evaluation of the predictive value of the body-mass-index choosing perforator flaps from different donor sites.

BACKGROUND: Free flap design must fulfill different criteria to ensure functional and aesthetic reconstruction of different types of defects in different body areas. A four-dimensional planning concept was used including flap length, width, thickness and tissue composition. This study evaluates if body-mass-index (BMI) has a predictive value for flap design. METHODS: A prospective study including hospitalized patients in the Department of Plastic, Aesthetic, Hand and Reconstructive Surgery was conducted. Not taking into account the reason for admission, the patients were examined based on age, weight, height, BMI and sex. The areas of a potential harvest of free fasciocutaneous and perforator flaps were measured using ultrasound examination to determine the thickness of the subcutaneous layers and prove blood perfusion. RESULTS: Over the period of four months, a total of 101 patients (36 females and 65 males) were included in this study and gave written consent. No statistical significance regarding the demographic data such as age, sex and BMI could be identified. An average to high correlation between free flap thickness and BMI was shown for the thoracodorsal artery perforator (TDAP), anterior lateral thigh (ALT) and deep inferior epigastric perforator (DIEP) flap in both, male and female patients. Free flaps of distal body parts such as the interosseous posterior flap, showed a lower correlation. No correlation using the Pearson coefficient could be found for age and volume. CONCLUSION: Our study demonstrated that the BMI is a predictive indicator that can be used in the preoperative planning of reconstructions using free flaps. Depending on the defect location, the BMI can be considered to predict the thickness of the free flap and may influence the surgeon's choice. On the other hand, a lower correlation between BMI and flap thickness encourages the use of standard flaps if more volume is desired, as the DIEP flap might be sufficient even in normal-weight women. Flaps of distal body parts, such as the forearm or lower leg, are not prone to such predictions and require other selection criteria.

Attempted Suicide by Burning: A Cross-sectional Analysis at a Regional Burn Center in Germany.

Attempted suicide by self-immolation or burning constitutes an uncommon form of attempted suicide in high income countries, presenting substantial challenges to burn units. The aim of this study was to analyze the epidemiologic characteristics and outcomes in intensive care burn patients treated for attempted suicide by burning. For this purpose, we examined intensive care burn patients admitted to a single major burn unit between March 2007 and December 2020. Demographic, clinical, epidemiological, and mortality data were collected and analyzed. Major psychiatric comorbidities were evaluated according to ICD-9 and ICD-10 classifications. A total of 1325 intensive care unit burn patients were included. Suicide by burning was attempted in 45 cases (3.4%). Attempted suicide victims presented with significantly higher burn severity, reflected by higher abbreviated burn severity index scores, and larger TBSA affected. Burned TBSA ≥30% and inhalation injuries were observed more frequently in suicidal patients. These patients also experienced prolonged hospital and intensive care unit length of stay, required surgical interventions and mechanical ventilation more frequently, and had significantly longer periods on ventilation, causing an overall higher mortality rate (24.4%). Psychiatric comorbidities were present in 75.6% of patients who attempted suicide. Despite the low prevalence, burn severity and mortality are considerably high in patients who attempted suicide by burning, presenting a significant challenge for healthcare providers. The majority of patients had a history of psychiatric disorder, highlighting the importance of identifying patients at high-risk who may profit from increased psychiatric intervention.

Epidemiology and outcome analysis of 1359 intensive care burn patients: A 14-year retrospective study in a major burn center.

AIMS: Globally, burn-related morbidity and mortality still remain high. In order to identify regional high-risk populations and to suggest appropriate prevention measure allocation, we aimed at analyzing epidemiological characteristics, etiology and outcomes of our 14-year experience with an intensive care unit (ICU) burn patient population. METHODS: A retrospective observational study was conducted including patients treated between March 2007 and December 2020 in our intensive care burn unit. Demographic, clinical and epidemiological data were collected and analyzed. RESULTS: A total of 1359 patients were included. 68% of the subjects were males and the largest age group affected entailed 45-64-year-old adults (34%). Regarding etiology, flame and contact burns were the most common in all age groups. Mean affected total body surface area (TBSA) was 13 ± 14.5% in all subjects. Most of the burns occurred domestically or during recreational activities. Mean hospital stay was 17.77 ± 19.7 days. The average mortality was 7.7%. The mortality rate showed an overall decreasing trend whilst burn severity remained consistent from 2007 to 2020. CONCLUSIONS: Despite consistent burn severity presentations of annual ICU admissions, burn injury mortality showed a decreasing trend, which was in part attributed to substantial progress in burn care and treatment and improved burn prevention awareness. Statistically significant age and gender differences could be detected with regard to burn etiology and seasonality, as well as outcomes, which highlight the importance of individualized primary prevention programs.

Intraneural Ganglion of the Peroneal Nerve-A Rare Cause of Pediatric Peroneal Nerve Palsy: A Case Report.

Intraneural ganglia are benign mucinous cysts located within the epineurium of a peripheral nerve. The pathogenesis and formation of intraneural ganglia are controversial. The main theories described in the literature are of degenerative, synovial or de novo occurrence. We present the case of a 14-year-old boy who presented in our outpatient clinic with a complaint of interdigital neuralgia between hallux and second toe, as well as left foot drop. MRI examination showed a hyperintense cystic distension of the common peroneal nerve measuring 130 mm × 5 mm extending from the poplitea to the anterior compartment of the leg. We performed microscopic decompression and neurolysis surgery. The cyst showed a sac-like distension at its distal end with connection to the tibiofibular joint and was resected. After 8 weeks, postoperatively, the boy claimed to be pain-free and slight recovery of the superficial peroneal nerve was noticed. At 6 months postoperative, the patient showed a continuous improvement of motor function, demonstrating foot eversion with 3/5 muscle strength and foot extension with 2/5 muscle strength. Intraneural ganglia reported for pediatric patients represent a very rare entity. To the best of our knowledge, less than 15 cases have been described within the English-speaking literature.

The Failed Breast Implant in Postmastectomy Reconstruction: A Systematic Literature Review of Complications of Implant-Based Breast Reconstruction.

BACKGROUND: Breast cancer is the most diagnosed malignant neoplasia of female patients worldwide in 2019. Survival has increased making it necessary to offer breast reconstructive procedures to improve quality of life and self-esteem. Implant-based breast reconstruction is the most common approach, making it necessary to quantify the associated complications. METHODS: A systematic literature review of the PubMed, Cochrane, and Web of Science databases was performed. A total of 9608 citations were identified, and 44 studies met the inclusion criteria. RESULTS: Studies included reported the incidence of complications either per patient or per breast leading consequently to 2 complication rates depending on the type of reporting. A total of 14.3% of patient-related and 28.8% of breast-related complications while undergoing implant-based reconstruction were reported.Among total complications reported, 72.6% of patient-related and 48.5% of breast-related complications were classified as major complications.A total of 37.6% of patients respectively 15.1% of breasts required prosthesis explantation due to severe complications. Depending on reporting, 9.7% of patients and 4% of breasts required autologous flap reconstruction due to reconstructive failure. CONCLUSIONS: High complication and failure rates are associated with implant-based breast reconstruction. Lacking randomized controlled trials, the choice between implant-based and autologous breast reconstruction has to be made individually for each patient.

Non-Invasive and Surgical Modalities for Scar Management: A Clinical Algorithm.

Scars can lead to aesthetic and functional impairments. The treatment of scars requires meticulous planning and an individually adapted therapeutic strategy. A conceptual algorithm for scar treatment makes everyday clinical work easier for the practitioner and offers more safety for the patient. Based on a retrospective analysis of 1427 patients who presented for treatment of a variety of scars, we developed an algorithm for scar management and treatment. The treatments are presented using case descriptions. Additionally, an electronic search of MEDLINE, EMBASE, and ClinicalTrials.gov databases was performed utilizing combinations of relevant medical subject headings for "scar treatment", "hypertrophic scar treatment" and "keloid treatment". Reference lists of relevant articles and reviews were hand-searched for additional reports. Observed outcomes included: conservative scar therapy, minimally invasive scar therapy, and surgical scar therapy using local, regional and free flaps. With this work, we provide an algorithm for safe scar treatment. For better understanding, we have described a clinical case for each algorithm modality.

Treatment of hand infections using WALANT -when the anesthesiologist is not available: A retrospective cohort study.

BACKROUND: The aim of this study was to determine, if Wide Awake Local Anesthesia No Tourniquet (WALANT) can be used as an alternative method of providing anesthesia in management of deep infections of the hand. Since the advent of WALANT in 2003, infections of the hand have been regarded as a contraindication to its use. Occasional shortage of anesthesiologic manpower, especially during busy call hours and the current COVID-19 pandemic can lead to delay of treatment where urgent surgery is needed, to prevent progress of an infection, that can result in severe morbidity. METHODS: In the period from 2015 to 2020, 16 patients with various infections of the hand underwent 17 operations using WALANT in a Hand Trauma and Replantation Center (HTRC) in Germany. Retrospective cohort analysis of their operation reports, with emphasis on location of infection, time and duration of the operation, intraoperative incidents and complications were carried out. We also evaluated the need for revision surgery or necessity to convert to general anesthesia and factors causing delay till the time of surgery. RESULTS: No case of inadequate analgesia, the need to convert to general anesthesia, ischemic events or cardiovascular complications with the use of the WALANT solution containing adrenaline and lidocaine in the treatment of deep tissue infections.The highest priority of limb preservation was ensured as no patient progressed to amputation of a digit or the hand. There was a statistically significant difference (p ≤ 0.01) in delay from the time of admission until surgery of up to 9h24 m (SD±3h34 m) during the week and 4h10 m (SD±2h28 m) during the weekend. CONCLUSION: The status of infection as an absolute contraindication to the use of WALANT should be revised. Especially when human resources are limited, WALANT is an adequate technique to enable quick anesthesia for urgent treatment to prevent progression of hand infections.

Paediatric hip ultrasound: uncertainties in examination and choice of treatment.

PURPOSE: In Germany, neonates undergo hip sonography examination using the Graf method during the routine U3 screening examination, performed by consultant physicians four to five weeks after birth, and are referred to specialized orthopaedic departments if there are any uncertainties. This study evaluated the quality of sonographic screening in the outpatient sector and the treatment requirements of referred children. METHODS: We performed a retrospective analysis of the patient data of 384 neonates collected in consultations performed between April 2016 and April 2019. RESULTS: In total, 74% (n = 284) of neonates presented a hip type Ia/b. Treatment (abduction brace or Fettweis cast) was required in 32% (n = 122) of cases. The treatment duration was significantly correlated with age at first presentation (Pearson's r = 0.678; p = 0.001). The treatment duration for patients aged > 200 days old at first presentation was twice as long as those aged 100 days at first presentation. Patients with public health insurance require referral by a consultant. Developmental dysplasia of the hip as referral diagnosis could not be confirmed in control examination in 64% (n = 132) of cases. Of the public health insured children, 97% (n = 200) were referred through a consultant paediatrician. CONCLUSION: We identified deficits in performing and interpreting the Graf method of ultrasound examination. A total of 64% of referred pathological hips turned out to be physiological configurations in our control examination. The future goal should be to increase anatomical knowledge of the newborn hip and ensure the correct use of Graf ultrasound method. Advanced training courses are recommended and necessary. LEVEL OF EVIDENCE: IV.
