Optimizing Interhospital Transfers in Orthopedics and Trauma Surgery: Challenges, Insights, and Proposals for Standardized Care in Germany.

BACKGROUND: Germany's high density of under-equipped hospitals and anticipated surge in orthopedic and trauma surgery-related diseases by 2030, combined with personnel shortages, are expected to increase patient transfers between hospitals, an issue that urgently needs standardized protocols. Despite some existing cooperative agreements, such as between joint-replacement centers or within the Trauma Network DGU®, these measures do not adequately address the full range of patient-transfer cases, including those due to a lack of specialization or staff shortages, resulting in delayed treatment and potential health risks. This study aims to dissect the intricacies of interhospital transfers in orthopedics and trauma surgery across Germany, focusing on understanding the underlying reasons for transfers, comparing the operational structures of small and large hospitals, and laying the groundwork for future standardized protocols to enhance patient care. MATERIAL AND METHODS: A cross-sectional study was conducted in the form of an online survey via SoSci Survey, which was directed at orthopedic surgeons and trauma surgeons working in hospitals in Germany. The 22-question survey gathered information on participants' clinic roles, departmental details, transfer processes, frequent diagnoses, perceptions of transfer quality, and improvement areas. The survey was sent to orthopedic and trauma surgeons in Germany by the specialist society. The data were analyzed using descriptive and inferential statistics to ensure a comprehensive insight into interhospital transfer practices. RESULTS: The study involved 152 participants from various hospital ranks and located in different hospital sizes and types across rural and urban areas. A significant difference was observed between the care structures of basic/regular care and central/maximum care hospitals, especially regarding the available facilities and specialties. These findings suggest improvements such as better patient documentation, increased digital communication, optimized patient distribution, and standardization of transfer requests, among others. CONCLUSIONS: This study highlights the urgent need for improved protocols and resource allocation to eliminate inequalities in transfers between hospitals in orthopedics and trauma surgery in Germany.

An Updated Overview of Risk Factors for Shoulder Stiffness. / Risikofaktoren für die Entstehung der primären Schultersteife: ein aktueller Überblick.

A painful reduction in shoulder mobility, known as "shoulder stiffness", can occur both as a primary idiopathic condition and as a secondary condition, for example, following surgical procedures. Various factors can contribute to the development of primary shoulder stiffness. In this review we summarize the pathophysiological mechanisms, genetic influences, endocrine disorders, metabolic conditions, as well as other diseases and medical-therapeutic approaches that might have an impact on the development of primary shoulder stiffness.

It is (not) always on Friday: inter-hospital patient transfers in orthopedic and trauma surgery.

BACKGROUND: While inter-hospital transfers for patients who have suffered major trauma have been well investigated, patient flows for other injured patients, or cases with orthopedic complications, are rarely described. This study aims to analyze the affected collective and to show possible reasons, patterns, and pitfalls to optimize the process in future. MATERIALS AND METHODS: In a prospective cohort study, all consecutive transfers to a Level I trauma center in Germany were documented and assessed. Patients suffering a major trauma were excluded. Data on the primary treating hospital, patient characteristics, and differences between emergency and elective surgery were analyzed. RESULTS: A total of 227 patients were included; 162 were injured, while 65 had suffered a complication after elective orthopedic surgery or had a complex orthopedic pathology. The most common diagnoses leading to transfer were pathologies of the extremities (n = 62), pathologies of the spine (n = 50), and infections (n = 18). The main reasons stated by the transferring hospitals were a lack of expertise (137 cases) and a lack of capacity (43 cases). There was a significantly higher rate of transfers due to trauma (n = 162) than for orthopedic patients (n = 65), p < 0.0001. CONCLUSION: There is currently no structured procedure or algorithm for transferring patients in orthopedics and trauma surgery.

Surgical Anatomy of the Radial Nerve at the Dorsal Region of the Humerus: A Cadaveric Study.

BACKGROUND: Surgery for humeral shaft fractures is associated with a high risk of iatrogenic radial nerve palsy (RNP). Plausible causes are difficult anatomical conditions and variants. METHODS: We performed a cadaveric study with 23 specimens (13 female and 10 male Caucasian donors) to assess the course and anatomy of the radial nerve (RN) with its branches alongside the humeral shaft. The accuracy of identification of the RN in the surgical field was analyzed by measuring the location, course, diameter, and form of each nerve and vessel of interest. RESULTS: The RN is not a single structure running alongside the humeral shaft; at least 4 parallel structures crossed the dorsal humerus in all subjects. The RN was accompanied by 2 vessels and at least 1 other nerve, which we named the musculocutaneous branch (MCB). With an oval profile and an average diameter of 3.1 mm (range, 2.6 to 3.8 mm), the MCB was thinner but, in some cases, close to the average diameter of 4.7 mm (range, 4.0 to 5.2 mm) of the RN, which had a round profile. Both accompanying vessels had similar diameters: 3.5 mm (range, 2.6 to 4.2 mm) for the radial collateral artery and 4.0 mm (range, 2.9 to 4.4 mm) for the medial collateral artery. In 20 (87%) of the cases, the RN ran proximal to and in 3 (13%) of the cases, distal to the MCB. Furthermore, a distal safe zone of at least 110 mm (range, 110 to 160 mm) was found, measured from the radial (lateral) epicondyle proximally. CONCLUSIONS: The RN does not cross the dorsal humerus alone, as often stated in anatomical textbooks, but runs parallel to vessels and at least 1 nerve branch with a similar appearance. Thus, for reliable preservation of the RN, we recommend identification and protection of all crossing structures in posterior humeral surgeries 110 mm proximal to the radial epicondyle.

Locking plate osteosynthesis of scaphoid nonunion with severe bone defects: a case series.

The treatment of scaphoid nonunion can be challenging with increasing defect size. We evaluated the outcome of scaphoid nonunion with a substantial bone defect treated with a multidirectional locking plate combined with cancellous bone grafting only. Thirteen patients with significant osseous defects measuring 6 mm or more suffering from primary nonunion without treatment (n = 6) or recalcitrant nonunion following Herbert screw osteosynthesis (n = 7) were treated and reviewed retrospectively. The stabilization was performed after debridement, autologous cancellous bone grafting and volar locking plate osteosynthesis. After a mean follow-up period of 12 months, 12 of the 13 patients achieved successful unions with a free range of motion and complete remittance of pain in everyday activity. The mean scapholunate angle decreased from 59.7° ± 11 to 43.9° ± 5 (effect strength d:1.7, p < 0.00001), scaphoid humpback deformity angle from 58.9° ± 8 to 45.1° ± 8 (d:1.8, p < 0.0001), whereas strength of the injured hand increased from 36.4 kg ± 10 to 42.4 kg ± 9 (d:1.4, p < 0.0001). One nonunion persisted without fragment dislocation receiving revision after 1 year. Thus, locking plate osteosynthesis with cancellous bone grafting is a valid alternative in scaphoid nonunions with extensive bone defects. Additionally, stable retention of the fragments prevents dislocation even in delayed or persistent nonunion. Further prospective studies are required to confirm these findings.

[Climate change: how surgery contributes to global warming]. / Klimawandel: Wie die Chirurgie zur Erderwärmung beiträgt.

BACKGROUND: Surgery as an important part of the healthcare sector contributes to environmental pollution and therefore to the climate crisis. The aim of this review is to create an overview of the current data situation and possibilities for improvement. METHODS: A literature search was performed in PubMed/MEDLINE using the following five terms: "carbon footprint and surgery", "climate change and surgery", "waste and surgery" and "greening the operating room" focusing on energy, waste, water and anesthesia. RESULTS: The greatest part of emissions in surgery is generated by the use of energy. The operating rooms (OR) need 3-6 times more energy than the other hospital rooms. Of the total hospital waste 20-30% is produced during operations, which is particularly due to the increasing use of disposable articles and 50-90% of waste classified as hazardous is incorrectly sorted. The disposal of this waste is not only more environmentally harmful but also much more expensive. The processing of surgical items by autoclaving consumes large amounts of water. Modern sterilization methods, for example using plasma could be future alternatives. Up to 20% of volatile nonmetabolized anesthetic agents are vented into the stratosphere and destroy the ozone layer. Intravenous anesthetic drugs should be used whenever possible instead. The choice of operating method can also contribute to the environmental impact of an operation. CONCLUSION: The surgical disciplines are a relevant producer of environmental pollutants. Through diverse interdisciplinary approaches surgery can also contribute to protecting the environment.

The Impact of Lead Aprons on Posture of Orthopaedic Surgeons. / Der Einfluss von Röntgenschürzen auf die Körperhaltung von Orthopäden und Unfallchirurgen.

BACKGROUND: Surgeons working in orthopedics and trauma surgery are frequently exposed to repetitive actions and non-ergonomic positions in their operative activities with the regular use of lead aprons. Musculoskeletal complaints of the neck and back among surgeons are reported in the literature as up to 80%. In this study, the effects of lead aprons on the posture of surgeons are examined using videorasterstereography, foot pressure measurement and questionnaires. METHODOLOGY: All subjects (n = 31) were examined before and after exposure to wearing lead aprons during surgery using videorasterstereography and pedography. In addition, a survey with a separately created questionnaire and the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was carried out. RESULTS: An average duration of lead apron use of 102.6 min showed an increase in forefoot load (p = 0.002) especially in the elderly subjects and thoracic kyphosis (p < 0.001) especially in the younger doctors with a significant lateral deviation (p = 0.006). In addition, the lateral deviation was shown to correlate with an increasing body size or a shorter period of employment (p = 0.008; r = 0.51/p = 0.026; r = - 0.44). Significantly fewer surgeons experienced back complaints on working days without lead apron use in the operating room compared to days in the OR (p = 0.011). CONCLUSION: The impact of wearing front covered lead aprons during operations in the field of orthopaedics and trauma surgery leads to more frequent back complaints, even among young and healthy doctors. Under an average duration of surgery of 102 min a temporary postural deviation occurs that can be demonstrated by means of videorasterstereography and foot pressure measurement. The subjects showed a shifted weight distribution on the forefoot, a gain in thoracic kyphosis and an increase in lateral deviation, which also correlated with an increasing height and shorter length of employment.

Reconstruction of Complicated Achilles Tendon Ruptures with Soft Tissue Defects - a Systematic Overview and Development of a Treatment Algorithm. / Rekonstruktion komplizierter Achillessehnenrupturen mit Weichteildefekten ­ eine systematische Übersicht und Entwicklung eines Behandlungsalgorithmus.

Achilles tendon ruptures are among the most common ruptures of large tendons. Due to the vulnerable soft tissue there is a high risk of soft tissue defects. The combination of Achilles tendon ruptures and soft-tissue defects remains a challenge for the surgeon. Despite different treatment options there is a lack of structured treatment recommendation. By means of a systematic literature review and experience from our own clinic standard, an overview of the stepwise treatment options is presented. A treatment algorithm for reconstructive measures of Achilles tendon ruptures accompanied by soft-tissue defects according to the length of defect of the Achilles tendon, the size of the soft-tissue defect and patient-individual factors is developed. This is intended to serve the surgeon as a basis for decision making prior to application of therapy.
