RESUMO
PURPOSE: With the growing technical options of power transmission and energy-saving options in electric drives, the number of E-bike-related accidents especially in an elderly population has increased. The aim of the current study was to compare if the increased velocity in comparison to conventional bikes translates into different injury patterns in the cranio-cervical and head region. METHODS: A retrospective cohort study was performed in patients admitted to our level one trauma center between 2009 and 2019 after being involved in an accident with either an E-bike, bicycle, or motorcycle and suffered cranio-cervical or traumatic brain injury. OUTCOMES: cranio-cervical/intracranial injury pattern. Data interpretation was conducted in an interdisciplinary approach. RESULTS: From 3292 patients treated in this period, we included 1068 patients. E-bikers were significantly older than bicyclists (or motorcyclists) and lay between the other two groups in terms of helmet use. Overall injury patterns of E-bikers resembled those found in motorcyclists rather than in bicyclists. E-bikers had a higher incidence of different cerebral bleedings, especially if no helmet was worn. Helmet protection of E-bikers resulted in a comparable frequency of intracranial bleeding to the helmeted bicyclists. CONCLUSION: The overall pattern of head and cervical injuries in E-bikers resembles more to that of motorcyclists than that of bicyclists. As they are used by a more senior population, multiple risk factors apply in terms of complications and secondary intracranial bleeding. Our study suggests that preventive measures should be reinforced, i.e., use of helmets to prevent from intracranial injury.
RESUMO
The "Remote Interactive Surgery Platform" (RISP) is an augmented reality (AR)-based platform for surgical telementoring. It builds upon recent advances of mixed reality head-mounted displays (MR-HMD) and associated immersive visualization technologies to assist the surgeon during an operation. It enables an interactive, real-time collaboration with a remote consultant by sharing the operating surgeon's field of view through the Microsoft (MS) HoloLens2 (HL2). Development of the RISP started during the Medical Augmented Reality Summer School 2021 and is currently still ongoing. It currently includes features such as three-dimensional annotations, bidirectional voice communication and interactive windows to display radiographs within the sterile field. This manuscript provides an overview of the RISP and preliminary results regarding its annotation accuracy and user experience measured with ten participants.
RESUMO
INTRODUCTION: The main objective of this study is to examine chronic pain and limping in relation to lower extremity and pelvic fracture location in addition to fracture combinations if multiple fractures are present on the same leg that have not been previously reported. We hypothesize that fracture pattern and location of lower extremity and pelvis fractures of multiple injured patients influence their long-term pain outcome. MATERIALS AND METHODS: Retrospective cohort study. Patients with treated multiple lower limb and pelvic fractures at a level 1 trauma center and followed up for at least 10 years postinjury were assessed. Lower leg pain subdivided into persistent, load-dependent and intermittent pain, as well as limping were recorded by using self-administered patient questionnaires and standardized physical examinations performed by a trauma surgeon. Descriptive statistics were used to present comparative measurements between groups. RESULTS: Fifty-seven percent of patients (n = 301) showed chronic lower limb pain 10 years postinjury. Ten percent of all patients with chronic pain displayed persistent pain, and here the most common fracture combination was tibial shaft fractures in combination with femoral shaft or proximal tibial fractures (13%). One hundred fifty-one patients reported load-dependent pain, with the most common fracture combinations being fractures of the foot in combination with femoral shaft fractures or distal tibial fractures (11%). One hundred twenty patients reported intermittent pain, with the most common fracture combinations involving the shaft of the tibia with either the femoral shaft or distal tibia (9%). Two hundred fifteen patients showed a persistent limp, and here the most common fractures were fractures of the femoral shaft (19%), tibial shaft (17%), and pelvis (15%). CONCLUSIONS: In multiple injured patients with lower extremity injuries, the combination of fractures and their location are critical factors in long-term outcome. Patients with chronic persistent or load-dependent pain often had underlying femoral shaft fractures in combination with joint fractures.

BACKGROUND: As electric bicycles (e-bikes) become increasingly popular, reports of injuries associated with e-bike usage are also rising. Patterns, characteristics, and severity of injuries following e-bike crashes need further investigation, particularly in contrast to injuries from conventional bicycle crashes. METHODS: This prospective observational study included 82 patients treated at a Level II trauma center for injuries resulting from an electric or conventional bicycle crash. Data were collected over one year (05.09.2017-19.09.2018) during in- and outpatient visits. A study-specific case report form was used to identify the bicycle type, cycling behavior (e.g., use of a helmet, safety gear, alcohol), and circumstances of the crash (e.g., road conditions, speed, cause of the incident, time of day, season). Additional information about patient demographics, treatment, and injury characteristics, such as the Injury Severity Score (ISS) and body region injured, were documented. Results were analyzed using chi-square, Fisher's exact, or Wilcoxon tests. Simple logistic or linear regression models were used to estimate associations. RESULTS: Of the 82 patients, 56 (67%) were riding a conventional bike and 27 (33%) were using an e-bike. Most incidents were either single-bicycle crashes (66%) or automobile collisions (26%), with no notable difference in prevalence rates between groups. Although a higher proportion of conventional bikers were male (67% vs. 48%), the difference was not significant. E-bikers were older (median 60 years (IQR 44-70) vs. 45 years (IQR 32-62); p = 0.008), were hospitalized more often (48% vs. 24%, p = 0.025), and had worse ISS (median 3 (IQR 2-4) vs. 1 (IQR 1-3), p < 0.001), respectively. Body regions most affected were the extremities (78%) and external/skin (46%), and these were distributed similarly in both groups. Concomitant injury patterns of the thorax/chest with external/skin were higher among e-bikers (p < 0.001). When we controlled for the difference in the median age of the two groups, only the injury severity score of e-bikers remained significantly worse. CONCLUSIONS: Hospitalization and chest trauma rates were higher among e-bikers. After controlling for the older age of this group, the severity of their injuries remained worse than in conventional cyclists. Initial clinical assessments at trauma units should include an evaluation of the thorax/chest, particularly among elderly e-bikers. LEVEL OF EVIDENCE: Level III.
RESUMO
BACKGROUND: A discoid lateral meniscus (DLM) is a congenital anomaly of the knee in which the lateral meniscus has an "O" shape and contains irregular, abnormal collagenous tissue. A DLM can cause mechanical symptoms and pain. Treatment of a symptomatic DLM is arthroscopic saucerization to reshape the meniscus to a more normal contour. Enough tissue must be removed to eliminate mechanical symptoms but not too much to create instability. The residual width of the meniscus is crucial at the popliteus hiatus because here the peripheral rim is unattached at the capsule. Reports in the literature recommend a residual width of 6 to 8 mm. PURPOSE/HYPOTHESIS: The purpose of this research was to determine the width of the lateral meniscus at the popliteal hiatus in normal specimens. Our null hypothesis was that a residual width of 6 to 8 mm will be sufficient to approximate normal anatomy. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: We made direct measurements of the radial width of the lateral meniscus from the outer rim at the popliteal hiatus to the inner edge in 19 specimens (age, 2-120 months.) We measured one 4-year-old specimen with a bilateral complete DLM. We also measured 39 digital images of specimens (age, 1-132 months) using ImageJ. Finally, we made direct arthroscopic measurements of 8 skeletally mature specimens. RESULTS: The average width of specimens <3 years old was 5.5 mm. The average width of the 10-year-old specimens was 12 mm. The average width of the skeletally mature specimens was 16 mm. A 4-year-old DLM specimen measured 19 mm. CONCLUSION: We rejected our null hypothesis. Direct measurements suggest that a residual width of 6 to 8 mm is insufficient for children ≥8 years old. A width of at least a full centimeter approximates the normal for 8-year-olds and at least 15 mm for adolescents.

Treatment strategies for anterior cruciate ligament (ACL) injuries continue to evolve. Evidence supporting best practice guidelines for the management of ACL injury is to a large extent based on studies with low-level evidence. An international consensus group of experts was convened to collaboratively advance towards consensus opinions regarding the best available evidence on operative versus non-operative treatment for ACL injury.The purpose of this study was to report the consensus statements on operative versus non-operative treatment of ACL injuries developed at the ACL Consensus Meeting Panther Symposium 2019. Sixty-six international experts on the management of ACL injuries, representing 18 countries, convened and participated in a process based on the Delphi method of achieving consensus. Proposed consensus statements were drafted by the Scientific Organising Committee and Session Chairs for the three working groups. Panel participants reviewed preliminary statements prior to the meeting and provided initial agreement and comments on the statement via online survey. During the meeting, discussion and debate occurred for each statement, after which a final vote was then held. Eighty per cent agreement was defined a priori as consensus. A total of 11 of 13 statements on operative veresus non-operative treatment of ACL injury reached consensus during the symposium. Nine statements achieved unanimous support; two reached strong consensus; one did not achieve consensus; and one was removed due to redundancy in the information provided.In highly active patients engaged in jumping, cutting and pivoting sports, early anatomical anterior cruciate ligament reconstruction (ACLR) is recommended due to the high risk of secondary meniscus and cartilage injuries with delayed surgery, although a period of progressive rehabilitation to resolve impairments and improve neuromuscular function is recommended. For patients who seek to return to straight plane activities, non-operative treatment with structured, progressive rehabilitation is an acceptable treatment option. However, with persistent functional instability or when episodes of giving way occur, anatomical ACLR is indicated. The consensus statements derived from international leaders in the field will assist clinicians in deciding between operative and non-operative treatment with patients after an ACL injury.Level of evidence: V.

Nonunion in the setting of chronic osteomyelitis after severe open ankle fractures is a feared outcome with severe loss in patient quality of life. Tibio-talo-calcaneal arthrodesis is a good salvage treatment option in this difficult patient cohort. We report a case of chronic osteomyelitis with severe destruction of the ankle joint after failed fracture fixation of an open trimalleolar ankle fracture. Fusion was ultimately achieved 5 years later using a novel-staged Masquelet technique with external ring fixator stabilization and bone graft reconstruction including femoral harvested autograft using reamer-irrigator-aspirator. This case shows that infection free arthrodesis of the ankle can be achieved even years after failed treatment. This procedure restored significant quality of life through pain relief and much improved mobility and may be a helpful technique in complex tibio-talo-calcaneal arthrodesis in the setting of chronic osteomyelitis and significant joint destruction.

PURPOSE: A stringent outcome assessment is a key aspect for establishing evidence-based clinical guidelines for anterior cruciate ligament (ACL) injury treatment. The aim of this consensus statement was to establish what data should be reported when conducting an ACL outcome study, what specific outcome measurements should be used and at what follow-up time those outcomes should be assessed. METHODS: To establish a standardized approach to assessment of clinical outcome after ACL treatment, a consensus meeting including a multidisciplinary group of ACL experts was held at the ACL Consensus Meeting Panther Symposium, Pittsburgh, PA; USA, in June 2019. The group reached consensus on nine statements by using a modified Delphi method. RESULTS: In general, outcomes after ACL treatment can be divided into four robust categories-early adverse events, patient-reported outcomes, ACL graft failure/recurrent ligament disruption and clinical measures of knee function and structure. A comprehensive assessment following ACL treatment should aim to provide a complete overview of the treatment result, optimally including the various aspects of outcome categories. For most research questions, a minimum follow-up of 2 years with an optimal follow-up rate of 80% is necessary to achieve a comprehensive assessment. This should include clinical examination, any sustained re-injuries, validated knee-specific PROs and Health-Related Quality of Life questionnaires. In the mid- to long-term follow-up, the presence of osteoarthritis should be evaluated. CONCLUSION: This consensus paper provides practical guidelines for how the aforementioned entities of outcomes should be reported and suggests the preferred tools for a reliable and valid assessment of outcome after ACL treatment.

RESUMO
BACKGROUND: Transitional fractures are fractures in adolescents where partial closure of the epiphyseal growth plate has occurred. These fractures are most commonly reported in the distal tibia. With respect to the distal radius, only a few case reports describing transitional fractures exist. Furthermore, relatively little is known about epiphyseal closure of the distal radius. A case series of four transitional fractures of the distal radius is presented by comparing non-operative and operative treatment options. At present, this is the largest case series in the literature dealing with this rare injury. CASE PRESENTATION: We present three cases of four transitional fractures of the distal radius including 1-year follow-up. Patient age ranged from 16 to 18 years including a gender ratio of two males to one female. Clinical and radiographic assessments took place 6 and 12 weeks and 1 year after trauma/surgery. Three transitional fractures were treated with open reduction and internal volar plate fixation followed by functional rehabilitation. One transitional fracture was treated non-operatively. All cases showed an excellent functional outcome. CONCLUSIONS: The primary treatment goal in transitional fractures is anatomic reduction of the articular surface. Non-operative treatment of transitional fractures of the distal radius is the most commonly reported treatment option. Additionally, different fixation options have been described, including the use of Kirschner wires (K-wires) and lag screws. The presented cases demonstrate that volar plate fixation followed by functional rehabilitation is a valuable treatment option in significantly displaced transitional fractures of the distal radius. Furthermore, we discuss the pathogenesis as well as the different treatment options by critical reviewing the literature.

PURPOSE: A precise and consistent definition of return to sport (RTS) after anterior cruciate ligament (ACL) injury is lacking, and there is controversy surrounding the process of returning patients to sports and their previous activity level. The aim of the Panther Symposium ACL Injury RTS Consensus Group was to provide a clear definition of RTS and description of the RTS continuum, as well as to provide clinical guidance on RTS testing and decision-making. METHODS: An international, multidisciplinary group of ACL experts convened as part of a consensus meeting. Consensus statements were developed using a modified Delphi method. Literature review was performed to report the supporting evidence. RESULTS: Key points include that RTS is characterized by achievement of the pre-injury level of sport and involves a criteria-based progression from return to participation to return to sport, and ultimately return to performance. Purely time-based RTS decision-making should be abandoned. Progression occurs along a RTS continuum with decision-making by a multidisciplinary group that incorporates objective physical examination data and validated and peer-reviewed RTS tests, which should involve functional assessment as well as psychological readiness. Consideration should be given to biological healing, contextual factors and concomitant injuries. CONCLUSION: The resultant consensus statements and scientific rationale aim to inform the reader of the complex process of RTS after ACL injury that occurs along a dynamic continuum. Research is needed to determine the ideal RTS test battery, the best implementation of psychological readiness testing and methods for the biologic assessment of healing and recovery. LEVEL OF EVIDENCE: IV.

BACKGROUND: Although of great value in the management of lateral clavicle fractures, substantial variation in their classification exists. We performed a retrospective study to address the inter- and intraobserver reliability of three different classification systems for lateral clavicle fractures. METHODS: Radiographs of 20 lateral clavicle fractures that represented a full spectrum of adult fracture patterns were graded by five experienced radiologists and five experienced trauma surgeons according to the Orthopaedic Trauma Association (OTA), the Neer, and the Jäger/Breitner classification systems. This evaluation was performed at two different time points separated by 3 months. To measure the observer agreement, the Fleiss kappa coefficient (κ) was applied and assessed according to the grading of Landis and Koch. RESULTS: The overall interobserver reliability showed a fair agreement in all three classification systems. For the OTA classification system, the interobserver agreement showed a mean kappa value of 0.338 ranging from 0.350 (radiologists) to 0.374 (trauma surgeons). Kappa values of the interobserver agreement for the Neer classification system ranged from 0.238 (trauma surgeons) to 0.276 (radiologists) with a mean κ of 0.278. The Jäger/Breitner classification system demonstrated a mean kappa value of 0.330 ranging from 0.306 (trauma surgeons) to 0.382 (radiologists).The overall intraobserver reliability was moderate for the OTA and the Jäger/Breitner classification systems, while the overall intraobserver reliability for the Neer classification system was fair.The kappa values of the intraobserver agreements showed, in all classification systems, a wide range with the OTA classification system ranging from 0.086 to 0.634, the Neer classification system ranging from 0.137 to 0.448, and a range from 0.154 to 0.625 of the Jäger/Breitner classification system. CONCLUSIONS: The low inter- and intraobserver agreement levels exhibited in all three classification systems by both specialist groups suggest that the tested lateral clavicle fracture classification systems are unreliable and, therefore, of limited value. We should recognize there is considerable inconsistency in how physicians classify lateral clavicle fractures and therefore any conclusions based on these classifications should be recognized as being somewhat subjective.
RESUMO
BACKGROUND: Surgical implant material has changed over time, from metal to stainless steel to titanium. In recent decades a new material, carbon-fibre-reinforced polyether ether ketone, has been introduced. The aim of this study was to assess the clinical and radiological feasibility and functional outcome after treatment of distal radius fractures with this new implant. METHODS: Inclusion criteria: AO type B distal radius fractures treated with 2.7 mm CF/PEEK plates at one Level 1 trauma centre between 2016 and 2017. Follow-up period 1 year, measurement of range of motion and radiographic assessment, histological analysis of debris only after plate removal. RESULTS: Out of 112 eligible patients, 10 (8.9%) patients were included. Mean operation time was 65 ± 10 min. Radiographic healing was confirmed by radiologists at 6 weeks follow-up. During one-year follow-up, no adverse events were reported and functionality and patients subjective satisfaction improved significantly (p < 0.05). Only one plate was removed, with no histological signs of inflammation or allergic reaction. CONCLUSIONS: The 2.7 mm CF/PEEK plate osteosynthesis appears to be a reliable and safe implant for certain types of distal radius fracture. Assessment of fracture union is substantially more practical and functionality improved significantly over 1 year.
RESUMO
INTRODUCTION: Falling on the outstretched arm is a frequent trauma. The consequences can be isolated fractures of the distal radius, combined fractures of the distal radius and distal ulna - whereas the isolated fracture of the distal ulna is an uncommon trauma. PRESENTATION OF CASE: We report on a 20- year- old male who presented at the emergency department after a motorcycle accident, suffering pain at his left forearm and left wrist. After an unremarkable x-ray in two planes, a CT- scan of the left wrist was performed and detected an isolated distal ulna fracture. The patient was treated with a forearm cast which led to a satisfying long term outcome. DISCUSSION: Based on the presented case the anatomical peculiarities of the distal radioulnar joint and the different trauma mechanisms as well as the resulting lesions, the diagnostic modalities and the treatment options are discussed. CONCLUSION: We recommend performing an additional CT scan of the wrist in case of credible complaints after trauma to avoid baulking this very rare type of fracture.
RESUMO
Avulsion fractures of the calcaneal tuberosity are predominantly seen in patients with poor bone quality, the commonly used lag screw fixation might not be strong enough even with bony fragments of sufficient size. We present a case of a closed displaced avulsion fracture of the calcaneal tuberosity due to blunt trauma to the calf in a 74-year-old female. Open reduction and internal fixation with two 3.5-mm cannulated cortical screws with washers was performed, and anatomic reduction was achieved. Without further trauma, secondary displacement of the fracture occurred on day 3. Revision was performed with a single 3.5-mm cortical screw and transosseous fixation with 2 suture anchors, followed by partial weightbearing for 6 weeks. At 12 weeks postoperative, the fracture had completely healed, and she was doing well at 16 months after the revision surgery. Transosseous suture anchor fixation of an osteoporotic avulsion fracture of the calcaneal tuberosity seems to provide better and stronger fixation than that using lag screws.

INTRODUCTION: While isolated traumatic urinary bladder injuries are rare, combined intra- and extraperitoneal traumatic urinary bladder ruptures without an underlying fracture are an absolute rarity. PRESENTATION OF CASE: We report a case of combined intra- and extraperitoneal urinary bladder rupture without an underlying fracture resulting from blunt abdominal trauma during a high velocity car accident. A midline laparotomy was performed, and the intra- and extraperitoneal bladder ruptures were surgically treated. DISCUSSION: Based on the presented case the anatomical peculiarities of the urinary bladder and the different trauma mechanisms as well as the resulting lesions, the diagnostic modalities and the treatment options are discussed. CONCLUSION: Despite the rarity of traumatic urinary bladder injuries, and especially in the absence of an underlying fracture, physicians should maintain a high level of suspicion for urologic injuries in the presence of nonspecific lower abdominal pain, gross haematuria and the inability to urinate.
