Since their introduction by Mennen and Wiese in 1993, semi-occlusive film dressings (SOFD) have been increasingly used in various clinical contexts, including the treatment of Allen type IV fingertip injuries, fingertip necrosis, and cases involving embedded foreign material.This study aimed to investigate whether and, if so, how the outcomes of Allen type III and IV fingertip injuries and fingertip necrosis differ from those of Allen types I and II. In addition, it aimed to investigate if the presence of embedded foreign material under a film dressing increases the risk of complications.A total of 50 patients with 44 fingertip injuries and 13 fingertip necroses were treated with an SOFD in combination with surgical intervention. In 22 out of 50 patients, foreign material was present under the film dressings. During follow-up, cold sensitivity, pain at rest and during activity, the usage of the injured finger in daily life, patient satisfaction with the aesthetic outcome, sensitivity, sweat secretion, papillary ridges, nail deformity, and mobility were assessed. The fingertips were examined for nail growth abnormalities. The results of the Allen type I-IV fingertip injuries and fingertip necrosis were compared with each other and related to findings from the uninjured fingers of the opposite hand. Clinical outcomes showed that SOFD led to good fingertip regeneration at any amputation level and in cases of fingertip necrosis. However, nail deformities increased with shorter lengths of the distal phalanx. Patients with necrosis were less satisfied with the aesthetic outcome compared to those receiving primary treatment after amputation injury. The presence of foreign material under the film dressings did not influence the healing process, and no infections were observed.SOFDs demonstrate good outcomes in Allen type III and IV fingertip injuries as well as in fingertip necrosis, comparable to those of Allen type I and II. However, it is essential to inform patients about potential risks such as nail deformities and compromised aesthetic appearance. Surgical interventions involving foreign material under an SOFD do not affect the healing of fingertip injuries, thus allowing for an expanded range of indications for SOFDs.

Introduction:   The entrance of Generation Z (born 1997-2012) into professional life, including the practice of medicine, marks a transformational shift in priorities and values. This generation, shaped by digital immersion and a strong focus on work-life balance, is redefining the landscape of Plastic Surgery. Their preferences for inclusivity, innovation, and structured working hours challenge traditional models of mentorship, patient care, and surgical training. The aim of this survey was to explore the impact of Generation Z on the field of Plastic Surgery through insights offered by leaders of major Plastic Surgery societies in Europe and the United States, who together provide a comprehensive perspective on generational change and its implications for clinical practice, education, and healthcare systems in Plastic Surgery.

Methods:   In October 2024 eight leaders of national Plastic Surgery societies and associations were invited to complete a structured questionnaire with five open-ended questions. They provided detailed responses on challenges, opportunities, and structural changes needed to address Generation Z's influence.

Results:   Key findings highlight a generational shift in the approach to professional life, with an emphasis on digital innovation, work-life balance, and the interaction with social media. Respondents noted an increased interest in aesthetic over reconstructive surgery and a preference for private practice among younger surgeons, raising concerns about workforce shortages in public healthcare. Advances in digital learning and simulation-based training were identified as opportunities to facilitate medical education. However, the ethical challenges of misinformation on social media and a decline in hierarchical mentorship were emphasized as critical concerns. Despite generational tensions, the integration of Generation Z's strengths in technology and advocacy for systemic reform holds promise for addressing burnout and enhancing healthcare delivery.

Conclusion:   The arrival of Generation Z in Plastic Surgery represents a possible pivotal moment to reimagine traditional models of surgical education, patient care, and professional priorities. Collaboration between generations and proactive adaptation to these changes is an imperative to ensure a dynamic, inclusive, and sustainable future for the specialty.

Purpose: This study aims to compare the clinical and radiological outcomes of three different techniques used in the surgical treatment of ulnar styloid fractures.

Material and method: Ulnar styloid fractures treated surgically between 2012 and 2022 were evaluated retrospectively. There were three groups in the study: Group I (Kirschner wire, N= 19), Group II (tension band, N= 27) and Group III (headless compression screw, N= 25). The Gaulke classification was applied to categorise the fractures. After a follow-up period of at least one year, range of motion, Modified Mayo Wrist Score (MMWS), Quick Disabilities of the Arm, Shoulder and Hand Score (QDASH), Visual Analogue Scale (VAS) and grip strength were measured. In addition, radiological union, bone resorption and dorsal subluxation of the DRUJ were evaluated.

Results: There was no difference between the three groups in terms of demographic data. Gaulke type 2 A was more frequently observed in all three groups (47.4%, 74.1%, 64%, respectively). Range of motion (flexion, extension, supination, pronation) was similar in all three groups (p>0.05). QDASH and MMWS were similar in all three groups. Grip strength was significantly lower in Group I than in Group II (p=0.039). Radiological outcomes (nonunion, dorsal subluxation, bone resorption) were similar in all three groups. Implant irritation was significantly higher in Group II (p=0.026).

Conclusion: K-wires, tension band wiring and headless compression screws yield similar clinical and radiological outcomes in the surgical treatment of unstable ulnar styloid fractures. However, the need for secondary surgery is more frequent when a tension band is used.

Level of evidence: Level IV.

This study aimed to evaluate the advantages and disadvantages of early versus delayed single-stage surgery in patients with hand enchondromas who developed pathological fractures, focusing on local tumor control and hand function, to determine the optimal timing for surgery. Delayed surgical curettage may offer advantages regarding both local tumor control and hand function outcomes.Thirty-five patients who developed pathological fractures due to solitary hand enchondromas and underwent surgical treatment between 2015 and 2021 were analysed. Patients were divided into two groups based on the timing of surgery. Patients who underwent surgical treatment immediately after a pathological fracture were assigned to the early-surgery group, and those who underwent surgical treatment after waiting for fracture union were assigned to the late-surgery group. Demographic data, lesion characteristics, and fixation methods were analysed. Parameters affecting outcome measurements were analysed, including visual pain scale, fracture healing time, recurrence, ROM, time to return to daily activities, and secondary surgical procedures.The study included 35 patients, of whom 24 were female, with a median age of 33 years. Fifteen patients were included in the early-surgery group and 20 in the late-surgery group, with a follow-up period of 36.3 and 38.9 months, respectively. The duration of surgery, time to fracture union, and total physical therapy duration during treatment were lower in the late-surgery group (p<0.05). At the final follow-up, the mean loss of ROM was 17.6˚ in the early-surgery group and 3.3˚ in the late-surgery group (p=0.00). The rate of secondary surgery was higher in the early-surgery group (p=0.040).In patients with hand enchondromas presenting with pathological fractures, early surgery resulted in higher complication rates, poorer functional outcomes, and an increased need for secondary surgeries.

Background: A preoperative informed consent discussion is an essential element of surgical treatment. Suspected errors in informed consent are frequently the subject of medical liability cases. To ensure a comprehensive documentation of the informed consent discussion, commercial documentation forms are available. Thanks to their comprehensiveness, they are increasingly replacing conventional, typically self-designed forms. In this study, the quality of informed consent discussions was evaluated based on the retrievable knowledge of the informed patients. Informed consent discussions based on self-designed forms were compared with those based on a commercial form.

Materials and methods: A monocentric, prospective, randomised, controlled, clinical longitudinal study was performed with 261 patients. Study participants were randomised into two groups. Informed consent discussions held in group A were documented using a self-designed form, while a commercial form (Thieme Compliance) was used for group B. Data collection was conducted through interviews using a standardised questionnaire, which each participant completed twice: once immediately after the medical informed consent discussion, and again on the morning of the surgery. The average time interval between the informed consent discussion and the surgery was 19 days.

Results: In both groups, the results were approximately the same. Overall, 98% of the respondents felt well or very well informed after the informed consent discussion and were satisfied with the manner of communication and the time frame. Accordingly, 77% of the respondents were not or only slightly nervous about the upcoming surgery. 85% of the participants correctly stated their diagnosis, and 80% correctly identified the planned surgery. However, 24% of the respondents were unable to actively name any of the complications mentioned in the discussion. Preoperatively, this percentage increased to 35%. Following the informed consent discussion, 44% of the respondents were able to list one to two complications, 27% were able to list three to four, and 5% were able to list five or more. Patients in group A tended to perform slightly better.

Conclusion: Similar results can be achieved even if different consent forms are used. Patients are well-informed immediately before hand surgery procedures. High patient satisfaction can be achieved through individualised design and documentation.

Background: The treatment of severely burned patients is demanding and necessitates specialised centres capable of providing adequate therapy over several months. The establishment of digital management systems in intensive care units signifies a substantial advancement in modern healthcare. Introducing such a system in a specialised intensive care unit for severe burn patients presents opportunities for optimisation but also potential obstacles. This study aims to provide insights into the perception of change from the perspective of staff and discuss the implementation of digital systems in the field of intensive care medicine.

Methods: After a selective sample was established, the impacts of the digital management system were examined across various categories. The data collected through a questionnaire and brief interviews were evaluated in terms of average values within each category, with interpretations taking into account characteristics such as professional group and work experience.

Results: Overall, the digital management system is considered suitable for use in the intensive care unit for severe burn patients by both medical and nursing staff. The continuous monitoring of vital parameters and the reduction of errors in medication administration are highlighted as positive aspects. However, negative points include the inferior documentation of burn wounds and specialised documentation for burn patients.

Conclusion: In due consideration of various factors such as experience, team size, and patient clientele, which impact the usability of the program, some aspects in need of improvement were identified. In summary, however, it can be said that there was a positive and favourable consensus regarding the introduction of such a system in the intensive care unit. Additionally, it can be concluded that the system is described as significantly more effective for a general surgical intensive care unit than for a specialised intensive care unit, e. g. an intensive care unit for severe burn patients.

Background: Liposuction for stage III lipoedema is a guideline-based but also time-consuming treatment, which can be carried out under specific conditions at the expense of the German statutory health insurance companies (SHI) based on a decision made by the German Federal Joint Committee ("Gemeinsamer Bundesausschuss", G-BA), the highest decision-making body in the German healthcare system, in 09/2019. We postulate that the treatment is not reflected in a cost-covering manner in the university cost system.

Methods: This monocentric, retrospective study examined the economic aspects of 92 cases in 48 lipoedema patients treated during the period from 09/2019 to 08/2023 at the expense of the SHI. These cases were filtered out using DRG coding and the Operation and Procedure Classification system ("Operationen- und Prozedurenschlüssel", OPS), and the costs and revenues per patient were calculated using the data from our internal service accounting.

Results: After an inpatient stay of 2.64±1.33 days, the total revenue was € 4,726.79±680.98. This included € 1,532.92±856.99 inpatient costs, € 2,686.02±1,174.70 in operating costs, € 940.76±189.18 in anaesthesia costs and € 63.19±125.38 in other costs that had to be paid within the clinic. On average across all treatments, this resulted in a loss of -€ 875.22 /case. In 54 cases (59%), the costs exceeded the revenue. In total, the calculation of all cases resulted in a loss of € -80,520.63. If medical personnel costs are included, this amount rises to over € 100,000.

Conclusion: The results show that the surgical treatment of lipoedema in the German DRG and university cost systems is not cost-covering. This could be relevant in the final economic assessment of the G-BA, which may result in an adjustment of the DRG revenue.

Introduction: Although DIEP (deep inferior epigastric perforator) is the gold standard for breast reconstruction, long-term results with a view to postoperative hairiness and flap skin colouration have rarely been described in the literature.

Methods: Patients who underwent DIEP flap breast reconstruction followed by NAC reconstruction between 2010 and 2019 were invited to our clinic for a survey and a clinical examination. A total of 781 patients were invited. The survey included the BREAST-Q and a study-specific questionnaire. The clinical examination contained specific measurements regarding postoperative hairiness and skin colouration.

Results: A total of 179 patients were examined, with 203 breasts having been reconstructed. Only breasts with a visible flap skin island were taken into further evaluation. A total of 109 DIEP flap and 77 NAC reconstructions were evaluated. In the patient-reported survey, 27.5% (30 of 109) reported additional flap hairiness and 62.4% (68 of 109) reported differences in flap skin colouration compared with the surrounding skin. The clinical examination revealed a significant difference between the skin colouration of the flap compared with the surrounding skin and the skin colouration of the reconstructed NAC compared with the existing original NAC. In both cases, the reconstructions appeared significantly "lighter" (p<0.05). No significant difference was found between patients with and without hair in terms of overall satisfaction evaluated by using the BREAST-Q. Neither did the colour difference have a significant influence on patients' satisfaction.

Conclusion: Additional breast hairiness and different skin colouration is relevant and should be communicated preoperatively.

Background: Apart from surgical procedures for breast and buttock augmentation, copolyamide fillers can be locally injected for an increase in volume. This method is especially popular in Asia.

Patient: A 39-year-old female patient had received a buttock augmentation by injection of a copolyamide filler. She presented with multiple abscesses six years after the augmentation. She had developed multiple fistulas and the filler had migrated down to the thigh muscles.

Results: In the presented case, the patient experienced multiple complications such as abscess formation, filler migration and chronic infection, with a significant time delay. Complete removal of the filler is only possible by removing surrounding tissue as well. Surgical treatment with repeated debridements and administration of an intravenous broad-spectrum antibiotic are the current standard of care. In contrast, the SWOP technique presented here appears to be less invasive and less likely for local recurrence.

Conclusion: A breast or buttock augmentation with copolyamide fillers is associated with a high risk of abscess and fistula formation leading to a permanent disfigurement of the patient.

Background: Achieving a medical professorship marks a significant step in a doctor's academic career, associated with a significant level of responsibility and obligations. The requirements to obtain a medical professorship in Germany vary significantly.

Material and methods: Based on an online search, we studied the statutes and regulations of medical faculties in Germany to determine the requirements for habilitation and an extraordinary professorship within Germany. All 38 German medical faculties were included. The evaluation was carried out for performance requirements in the areas of teaching and research.

Results: The general requirement for a habilitation application is the completion of the medical specialist certification examination. On average, 2.3 years of teaching activity are expected. The minimum number of teaching hours averages 2.6 weekly semester hours. An average of at least 11 publications are required. Of these, an average of 7 must be written as first or last author. For an extraordinary professorship, an average of 4.4 years (min. 2, max. 6) of teaching activity after habilitation is required. The minimum number of teaching hours in semester hours averages 1.9 hours (min. 1, max. 2). The minimum number of publications averages 9 publications (min. 4, max. 24), of which an average of 6.3 must be written as first or last author.

Conclusion: The requirements for habilitation and extraordinary professorship in Germany vary, especially with a view to publications and teaching. Depending on the faculty, lower publication numbers can be compensated by higher "impact factors". Furthermore, there is no national standardisation and comparability in the field of medical academic graduations.
