Introduction: Trauma surgeons are often less exposed to large caseloads of primary osteoarthritis, compared to purely “elective”orthopaedic surgeons. The experience in total knee arthroplasty is thereby markedly On the other hand, posttraumatic knee arthrosis is often accompanied by severe deformity and axis deviation. In theory, navigated arthroplasty can overcome some of the problems in this setting. Aim: Evaluation of the navigated technique of total knee arthroplasty (TKA), including the technical difficulties, the learning curve and the feasibility in severe bony deformity. Setting is a level I trauma center. Study setup was prospective, follow up period on average 14.5 months (11–25 months). Patients: Between 7/04–6/05 we treated 36 patients with arthritis of the knee related to trauma. 18 patients were male. Average age at TKA was 59 (32–77) years. On average patients had 2.83 previous operations. Methods: The navigational system used is manufactured by PRAXIM (La Tronche/France). It uses infrared-tracking and bone-morphing software. The implant was a mobile bearing LCS knee (DePuy/USA). Follow up included radiographs, clinical examination and the knee society scores. Results: In three cases the procedure was finished in a conventional technique, reasons were suspicion of the surgeon about the cuts recommended by the system, a missing femoral cut block and a broken screw of the tracker-fixation. There was no failure of the navigational system. There was a clear learning curve regarding procedure time. Preop mean extension deficit was improved from av. 7.1° (0–30°) to 1.67° (0°–10°) postop., flexion contracture improved from av. 95° to 103°. The combined knee society score (max. 200 pts) improved from 77 pts preop to 156 pts at follow up. Conclusions: Navigated knee endoprosthesis is reliable tool for the trauma surgeon with few technical problems. Especially for surgeons with less experience in TKA, planning of implant size and position is very helpful. With posttraumatic deformity the surgeon can gain valuable information and assistance to improve alignment and ligamentous balancing

Aims. The aim of this study was to investigate the association between fracture displacement and survivorship of the native hip joint without conversion to a total hip arthroplasty (THA), and to determine predictors for conversion to THA in patients treated nonoperatively for acetabular fractures. Methods. A multicentre cross-sectional study was performed in 170 patients who were treated nonoperatively for an acetabular fracture in three level 1 trauma centres. Using the post-injury diagnostic CT scan, the maximum gap and step-off values in the weightbearing dome were digitally measured by two trauma surgeons. Native hip survival was reported using Kaplan-Meier curves. Predictors for conversion to THA were determined using Cox regression analysis. Results. Of 170 patients, 22 (13%) subsequently received a THA. Native hip survival in patients with a step-off ≤ 2 mm, > 2 to 4 mm, or > 4 mm differed at five-year follow-up (respectively: 94% vs 70% vs 74%). Native hip survival in patients with a gap ≤ 2 mm, > 2 to 4 mm, or > 4 mm differed at five-year follow-up (respectively: 100% vs 84% vs 78%). Step-off displacement > 2 mm (> 2 to 4 mm hazard ratio (HR) 4.9, > 4 mm HR 5.6) and age > 60 years (HR 2.9) were independent predictors for conversion to THA at follow-up. Conclusion. Patients with minimally displaced acetabular fractures who opt for nonoperative fracture treatment may be informed that fracture displacement (e.g. gap and step-off) up to 2 mm, as measured on CT images, results in limited risk on conversion to THA. Step-off ≥ 2 mm and age > 60 years are predictors for conversion to THA and can be helpful in the shared decision-making process. Cite this article: Bone Joint J 2023;105-B(9):1020–1029

Classification systems for tibial plateau fractures suffer from poor interobserver agreement, and their value in preoperative assessment to guide surgical fixation strategies is limited. For tibial plateau fractures four major characteristics are identified: lateral split fragment, posteromedial fragment, anterior tubercle fragment, and central zone of comminution. These fracture characteristics support preoperative assessment of fractures and guide surgical decision-making as each specific component requires a respective fixation strategy. We aimed to evaluate the additional value of 3D-printed models for the identification of tibial plateau fracture characteristics in terms of the interobserver agreement on different fracture characteristics. Preoperative images of 40 patients were randomly selected. Nine trauma surgeons, eight senior and eight junior registrars indicated the presence or absence of four fracture characteristics with and without 3D-printed models. The Fleiss kappa was used to determine interobserver agreement for fracture classification and for interpretation, the Landis and Koch criteria were used. 3D-printed models lead to a categorical improvement in interobserver agreement for three of four fracture characteristics: lateral split (Kconv = 0.445 versus K3Dprint = 0.620; P < 0.001), anterior tubercle fragment (Kconv = 0.288 versus K3Dprint = 0.449; P < 0.001) and zone of comminution (Kconv = 0.535 versus K3Dprint = 0.652; P < 0.001). The overall interobserver agreement improved for three of four fracture characteristics after the addition of 3D printed models. For two fracture characteristics, lateral split and zone of comminution, a substantial interobserver agreement was achieved. Fracture characteristics seem to be a more reliable way to assess tibial plateau fractures and one should consider including these in the preoperative assessment of tibial plateau fractures compared to the commonly used classification systems

The purpose of this project was to evaluate North American trauma surgeon preferences regarding patient positioning for antegrade fixation of mid shaft femoral shaft fractures. This project was a cross sectional survey taken of orthopaedic fellows and staff surgeons, belonging to three organizations across North America. An estimated sample size was calculated a priori, while various online techniques were utilized to reduce non responder and fatigue bias. The survey was distributed multiple times to optimize yield. Two hundred twelve (212) participants responded in full, 134 (56%) of whom practiced in Canada. The majority of surgeons worked in level one trauma centres (74%), while 72% treated more than one femoral shaft fracture per week. The most common patient position for mid shaft fixation amongst all surgeons was lateral positioning with manual traction (68%), however community surgeons were significantly more likely to use a fracture table. The most common difficulties faced with using a fracture table were inability to achieve fracture reduction and peroneal nerve palsies. The majority (64%) of surgeons quoted a complication rate with fracture tables of greater than 1 per 100 cases. Lateral position with use of manual traction is the preferred set up for antegrade fixation of femoral shaft fracture in this large North American cohort of trauma surgeons. However, a large subset of community and non academic surgeons still prefer use of the fracture table. Amongst all respondents, a high rate of fracture table complications, including malreduction, were quoted. To date, there is no prospective data comparing these two options for patient positioning, and a randomized controlled trial may be an appropriate next step

Aim. Infection rates after management of open fractures are still high. Existing guidelines regarding prevention of this complication are inhomogeneous. A survey directed to orthopaedic trauma surgeons worldwide aims to give an overview of current practices in the management of open fractures. Method. An international group of trauma surgeons and infection specialists with experience in the field of musculoskeletal infections developed a questionnaire that was distributed via email to all AOTrauma members worldwide. Descriptive statistical analysis was performed. Results. 1197 orthopaedic trauma surgeons answered the survey (response rate: 4,9% of all opened emails). Cephalosporins are the most commonly used antibiotics for systemic prophylaxis in open fractures (cefazolin: 51,46% cefuroxime: 23,6%, ceftriaxone: 14,54%). In Gustilo type III open fractures gentamicin (49,12%) and metronidazole (33,58%) are often added. 86% (n=1033) reported to give the first dosage of systemic antibiotics in the emergency department as soon as the patient arrives. Only 3% (n=34) reported pre-hospital administration at the scene of the accident or during transport to the hospital. While most respondents administer antibiotics over 24h in type I open fractures (34%, n=405), for type II open fractures the most often mentioned duration is 72h (26%, n=306). For type III a 7 days course was most often performed (38%, n=448). Overall, there is a tendency to longer durations with increasing severity. However, a vast majority agreed that the optimal duration is not well defined in the literature (71%, n=849). 20psi,”Jet-Lavage”). The amount of irrigation fluid has a bimodal distribution with two peaks at 4–6 liters (24%, n=286) and at 8–10 liters (24%, n=282). Conclusions. Results from our survey give an overview of current practices and identify certain aspects in the management of open fractures where treatment protocols are very heterogenous and guidelines not well accepted. These controversies demand for further research in this field to provide better evidence

Introduction. Current undergraduate trauma and life-support training inadequately equips medical students with the knowledge, practical skills and confidence to manage trauma patients. Often first to the scene of medical emergencies, it is imperative junior doctors feel confident and competent from day one. No UK university currently includes advanced trauma and life support (ATLS) in their curriculum. This study piloted an ATLS course for Cardiff final-year medical students to improve confidence and knowledge in management of the trauma patient. Aim. To assess the immediate effect of a one-day undergraduate ATLS course on medical student's confidence in management of the trauma patients. Methods. Twelve final-year students attended a one-day, practical-skills based and interactive course led by trauma surgeons. Students' confidence managing a trauma patient were assessed pre and post-course using a six-item-MCQ with a 5-point Likert scale. Paired t-tests were carried out on SPSS for comparison pre and post-course across the six items. Qualitative feedback was also collected. Results. The students' confidence in managing a trauma patient's ‘airway and breathing’, ‘circulation’ and ‘C-spine’ all significantly improved after attending the course (p=0.023, p=0.045 and p=000 respectively). Students felt significantly more confident completing practical skills related to trauma (p= 0.001) and their confidence in managing trauma patients overall at the level expected of a Foundation doctor increased significantly (p= 0.003). Qualitative feedback demonstrated high faculty-to-student ratio, practical and interactive teaching methods were particularly helpful. Conclusion. The content and delivery of this course proved beneficial for final-year medical students imminently becoming Foundation doctors, evidencing the requirement for increased trauma training. We advocate the expansion and continuation of this novel student course to continue improving the trauma training within the undergraduate curriculum

Abstract. Introduction. Minimising postoperative complications and mortality in COVID-19 patients who were undergoing trauma and orthopaedic surgeries is an international priority. Aim was to develop a predictive nomogram for 30-day morbidity/mortality of COVID-19 infection in patients who underwent orthopaedic and trauma surgery during the coronavirus pandemic in the UK in 2020 compared to a similar period in 2019. Secondary objective was to compare between patients with positive PCR test and those with negative test. Methods. Retrospective multi-center study including 50 hospitals. Patients with suspicion of SARS-CoV-2 infection who had underwent orthopaedic or trauma surgery for any indication during the 2020 pandemic were enrolled in the study (2525 patients). We analysed cases performed on orthopaedic and trauma operative lists in 2019 for comparison (4417). Multivariable Logistic Regression analysis was performed to assess the possible predictors of a fatal outcome. A nomogram was developed with the possible predictors and total point were calculated. Results. Of the 2525 patients admitted for suspicion of COVID-19, 658 patients had negative preoperative test, 151 with positive test and 1716 with unknown preoperative COVID-19 status. Preoperative COVID-19 status, sex, ASA grade, urgency and indication of surgery, use of torniquet, grade of operating surgeon and some comorbidities were independent risk factors associated with 30-day complications/mortality. The 2020 nomogram model exhibited moderate prediction ability. In contrast, the prediction ability of total points of 2019 nomogram model was excellent. Conclusions. Nomograms can be used by orthopaedic and trauma surgeons as a practical and effective tool in postoperative complications and mortality risk estimation

Tibial plateau fractures classically present in a bimodal distribution associated with high energy mechanisms in the younger population and fragility fractures in the elderly populations as a result they are well suited for looking at the effect major trauma centre status. Military trauma surgeons in training should be exposed to as much young high-energy trauma as possible to equip them for operations. Retrospective review of all tibial plateaus presenting to RVI 20 months before MTC status and 20 months following this. 61 patients pre, 66 post. Schatzker grade 1–4 were similar pre and post change. Post change there was an increase in Schatzker 5 (62%) and 6 (27%). High energy injuries were most common in younger males, cause was falls followed by RTAs. MTC status has meant an increase in high energy tibial plateaus (Schatzker 5–6) These were predominantly seen in younger males with high-energy mechanisms. As this is likely to be replicated across all injuries, we would recommend military trauma surgeons have a significant period of time training in major trauma centres to ensure adequate exposure to young high energy trauma

Routine metalwork removal, in asymptomatic patients, remains a controversial issue in our daily practice. Current literature emphasized the potential hazards of implant removal and the financial implications encountered from these procedures. However, there is little literature guidance and no published research on current practice. To estimate the current state of practice of orthopaedic surgeons in the United Kingdom regarding implant removal for limb trauma in asymptomatic patients, an analysis of the postal questionnaire replies of 36% (500 out of 1390) of randomly selected UK orthopaedic consultants was performed by two independent observers. 47.4% replies were received. A total of 205 (41%) were found to be suitable for analysis. The most significant results of our study I: 92% of orthopaedic surgeons stated that they do not routinely remove metalwork in asymptomatic skeletally mature patients. II: 60% of trauma surgeons stated that they do routinely remove metalwork in patients aged 16 years and under, while only 12% of trauma surgeons do routinely remove metalwork in the age group between 16–35 years. III: 87% of the practising surgeons indicated that they believe it is reasonable to leave metalwork in for 10 years or more. IV: Only 7% of practising trauma surgeons replied to this questionnaire have departmental or unit policy. No policy is needed for metalwork removal, as most of the orthopaedic surgeons were complying with literature guidance supporting the potential risks associated with implant removal, in spite of the limited number of departmental or units’ policies on implant removal and the paucity of the literature documenting the current practice. However, there is a discrepancy among trauma surgeons in relation to metalwork removal between patient age groups. This indicates guidelines would be helpful to guide the surgeon for the best practice. This is important from a medico-legal standpoint because surgeons are being criticised for not achieving satisfactory results in negligence cases

Introduction. Orthopaedic trauma surgery is characterised by repetitive, forceful tasks that are physically demanding, thus theoretically increasing the risk of musculoskeletal injuries in these surgeons. The aim of this study is to assess prevalence, characteristics and impact of musculoskeletal disorders among orthopaedic trauma surgeons. Methods. A modified version of the physical discomfort survey was sent to surgeon members of the Orthopaedics Trauma Association (OTA) via e-mail. For data analysis, one-way ANOVA and Fisher Exact test were performed to compare the variables where appropriate. P values<0.05 were considered statistically significant. Results. A total of 86 surgeons completed the survey during the period of data collection. Of the respondents 84.9% were males and more than half were aged between 30–45 years old. The majority of musculoskeletal complaints and disorders were low back pain (29.3%), wrist or forearm tendinitis (18.0%), elbow lateral epicondylitis (15.4%), plantar fasciitis (14.7%). When data was analysed according to number of years in practice the results yielded a significant difference between the groups in both number of regions involved (p<0.05) and number of musculoskeletal disorders (p<0.05), as a higher proportion of these were documented in surgeons practicing for 16–20 years and more than 30 years. Also surgeons working in a private setting (p<0.005), surgeons working in more than one institute (p<0.005), increased number of regions involved (p<0.001) and increased number of musculoskeletal disorders (p<0.001) were significantly more likely to require time-off work. Conclusion. To our knowledge, our study is the first of its kind that shows a high percentage of orthopaedic trauma surgeons sustain occupational injuries some time in their careers. Cost of management and rehabilitation of these injuries, in addition to the amount of missed workdays due to these injuries indicate that these injuries have a significant economic burden on the health-care system

Objectives. To explore whether orthopaedic surgeons have adopted the Proximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial results routinely into clinical practice. Methods. A questionnaire was piloted with six orthopaedic surgeons using a ‘think aloud’ process. The final questionnaire contained 29 items and was distributed online to surgeon members of the British Orthopaedic Association and British Elbow and Shoulder Society. Descriptive statistics summarised the sample characteristics and fracture treatment of respondents overall, and grouped them by whether they changed practice based on PROFHER trial findings. Free-text responses were analysed qualitatively for emerging themes using Framework Analysis principles. Results. There were complete responses from 265 orthopaedic and trauma surgeons who treat patients with proximal humeral fractures. Around half (137) had changed practice to various extents because of PROFHER, by operating on fewer PROFHER-eligible fractures. A third (43) of the 128 respondents who had not changed practice were already managing patients non-operatively. Those who changed practice were more likely to be younger, work in a trauma unit rather than a major trauma centre, be specialist shoulder surgeons and treat fewer PROFHER-eligible fractures surgically. This group gave higher scores when assessing validity and applicability of PROFHER. In contrast, a quarter of the non-changers were critical, sometimes emphatically, of PROFHER. The strongest theme that emerged overall was the endorsement of evidence-based practice. Conclusion. PROFHER has had an impact on surgeons’ clinical practice, both through changing it, and through underpinning existing non-operative practice. Although some respondents expressed reservations about the trial, evidence from such trials was found to be the most important influence on surgeons’ decisions to change practice.

Three dimensional printing is an emerging new technology in medicine and the current educational value of 3D printed fracture models is unknown. The delayed surgery and need for CT imaging make calcaneal fractures an ideal scenario for preoperative 3D printed (3Dp) fracture models. The goal of this study is to assess if improvements in fracture understanding and surgical planning can be realized by trainees when they are given standard CT imaging and a 3Dp model compared to standard CT imaging and a virtual 3D rendering (3D CT). Ethics approval was granted for a selection of calcaneal fracture imaging studies to be collected through a practice audit of a senior orthopaedic trauma surgeon. 3Dp models were created in house. Digital Imaging and Communications in Medicine (DICOM) files of patient CT scans were obtained from local servers in an anonymized fashion. DICOM files were then converted to .STL models using the Mimics inPrint 2.0 (Materialise NV, Leuven, Belgium) software. Models were converted into a .gcode file through a slicer program (Simplify3D, Blue Ash, OH USA). The .gcode files were printed on a TEVO Little Monster Delta FDM printer (TEVO USA, CO USA) using 1.75mm polylactic acid (PLA) filament. Study participants rotated through 10 workstations viewing CT images and either a digital 3D volume rendering or 3Dp model of the fractured calcaneus. A questionnaire at each workstation assessed fracture classification, proposed method of treatment, confidence with fracture understanding and satisfaction with the accuracy of the 3Dp model or 3D volume rendering. Participants included current orthopaedic surgery trainees and staff surgeons. A total of 16 residents and five staff completed the study. Ten fracture cases were included in the analysis for time, confidence of fracture understanding, perceived model accuracy and treatment method. Eight fracture cases were included for assessment of diagnosis. There were no cases that obtained universal agreement on either Sanders classification or treatment method from staff participants. Residents in their final year of studies had the quickest mean time of assessment (60 +/− 24 sec.) and highest percentage of correct diagnoses (83%) although these did not reach significance compared to the other residency years. There was a significant increase in confidence of fracture understanding with increasing residency year. Also, confidence was improved in cases where a 3Dp model was available compared to conventional CT alone although this improvement diminished with increasing residency year. Perceived accuracy of the cases with 3Dp models was significantly higher than cases without models (7 vs 5.5 p < 0.0001). This is the first study to our knowledge to assess trainee confidence as a primary outcome in the assessment of the educational value of 3Dp models. This study was able to show that a 3Dp model aides in the perceived accuracy of fracture assessment and showed an improvement in trainee confidence, although the effect on confidence seems to diminish with increasing residency year. We propose that 3D printed calcaneal fracture models are a beneficial educational tool for junior level trainees and the role of 3Dp models for other complex orthopaedic presentations should be explored

The placement of the guide wire in the dynamic hip screw operation can be a challenging task to the trauma surgeon. Complications can arise related to incorrect guide wire entry point, making wrong tracks, or even accepting an unsatisfactory lag screw placement. Insisting to optimise the guide wire position can lead to increase in operation and radiation exposure times. A new non-invasive technique is described to assist precision placement of the guide wire in the dynamic hip screw fixation of the neck of femur fractures using no more than a size A4 plain folded paper and a non-permanent marker pen. The new non-invasive “no high tech” method can help the trauma surgeons to shorten the operation time and reduce the radiation exposure time needed to place the guide wire in the dynamic hip screw fixation of the neck of femur fractures

PURPOSE: To determine the capability of fellowship trained Orthopaedic Trauma surgeons to predict union or non-union of femoral and tibial shaft fractures. METHODS: A series of 50 patients with femur or tibia shaft fractures were evaluated. Patients were prospectively followed at 2,6,12, and 18 weeks after surgical intervention. At each interval surgeons evaluated factors related to fracture healing on AP and lateral radiographs and predicted the probability of union on a visual analog scale. Union was defined as radiographic evidence of healing three of four cortices, no tenderness with palpation of the fracture site, and full weight bearing without the use of assistive devices. RESULTS: Eight patients missed initial visits or were lost to follow-up, making for a total of 42 patients that were included in the results. Average patient age was 31 years. Eighty-one percent of the patients went onto union (N=34) and 19% went onto nonunion (N=8). Early clinical prediction for nonunion at 2 weeks had a sensitivity of 50%, a specificity of 91%, a positive predictive value (PPV) of 57%, and a negative predictive value (NPV) of 89%. At 6 weeks, there was a sensitivity of 75%, a specificity of 100%, a PPV of 100%, and a NPV of 94%. One patient treated with intramedullary nailing was 15 years old and despite minimal callous formation the physician incorrectly predicted future union given the young age. The other patient had a severely comminuted femur fracture and required a quad cane to ambulate and should perhaps have been predicted to go onto nonunion. At 12 and 18 weeks, sensitivity, specificity, PPV, and NPV were both 100%. CONCLUSIONS: Fellowship trained orthopaedic trauma surgeons at 6-week follow-up can predict union with a sensitivity of 75% and specificity of 100% and a PPV of 100%. Early clinical prediction at 6 weeks can be used to provide the patient with a secondary intervention such as a bone graft or bone stimulator and avoid months of delay

Objectives: To review the changing pattern of orthopaedic injury encountered by deployed troops with regard to the importance of hand trauma. Methods: A literature review of orthopaedic practice in recent conflict. The search period extended from 1990–2007. A subsequent search was performed to identify papers relating to hand injuries from 1914 to the present day. Papers were graded according to Levels of Evidence. Results: 210 published works were analysed. Review of the literature revealed a lack of statistical analysis and a tendency towards the anecdotal. The evidence is overall level 5 with the majority of papers comprising reviews, individual sub-unit experiences, historical perspectives and individual database analyses. The evolving importance of extremity trauma is clear from the quantity of its reporting. The paucity of life threatening cavity trauma is highlighted. Casualty survival off the battlefield is increasing perhaps due to the impact of personal protective equipment. The combination of changing ballistics and increasing survivability leads to an apparent increase in limb threatening and complex hand trauma being encountered by military surgeons. Despite being rarely reported in isolation, the proportion of complex hand trauma is broadening with an increase in open fractures and mutilated soft tissue injuries resultant from high and low energy transfer ballistics. Hand trauma is also shown to occur in deployed troops during activities unrelated to war fighting. Sporting activities and inappropriate use of equipment are responsible for soft tissue and bony injury with considerable morbidity. The literature was analysed with regard to the classification of hand trauma. Articles relating to recent conflicts were notable for their lack of classification of these injuries. The bulk of papers retrieved concerning military hand trauma management were published prior to the conflicts of the last decade. It is within these papers that classification and treatment priorities including the nature of debridement and fracture stabilisation are discussed and highlighted as core knowledge. Conclusion: The nature of injuries sustained by troops in conflict is evolving. Changing survivability is resulting in increasingly complex hand trauma presenting to military surgeons. Despite a culture of ensuring that today’s trauma surgeons learn from mistakes made by their predecessors, in the field of hand trauma this is not the case. A comprehensive review of changing orthopaedic conflict related injury patterns with special regard to hand trauma and the key learning points from historical literature are highlighted. Proposals for improving management are discussed with regard to improved training opportunities and dialogue between military trauma surgeons

Purpose: The use of radiology is integral to Orthopaedic Trauma surgery and there has been increasing dependence on image intensifiers in the operating room. A study was undertaken to assess the radiation exposure of the surgeon. Methods: One full time orthopaedic trauma surgeon has worn a dosimeter on his waist since November 1996, under a lead apron when using a large image intensifier and when using a mini C-arm. Since November 2001, a second dosimeter was worn at the neck, unshielded in all cases. Since June 2005, a ring dosimeter was worn on the dominant ring finger and the all surgical cases were prospectively documented in regard to the type of intensifier used and the amount of fluoroscopy used. Results: In the nine years of monitoring the truncal dosimeter has never recorded any radiation. In four years of monitoring the neck dosimeter has recorded 5.72 mSv (average 1.4 mSv / yr). In last 2 months (6 months data will be available at the time of presentation), 99 operative cases were done. In 31 cases no intra-operative radiology was used, 33 cases used a mini C-arm and in 35 cases a large C-arm was used. A total of 40.2 minutes of mini fluoro time (average 1.22 minutes / case) and 118.09 minutes of full sized C-arm fluoro time (average 3.37 minutes / case) was used. In these 2 months the ring dosimeter recorded 5.4 mSv of radiation (annualized dose 32.4 mSv). Conclusions: The International Commission on Radiological Protection annual recommended dose limits for “radiation workers” are: whole body 20 mSv, eyes 150 mSv and skin / hands 500 mSv. For members of the public these limits are 1 mSv, 15 mSv and 50 mSv, respectively. The exposure of an Orthopaedic Trauma surgeon fall well below the annual recommended dose limits in the industry but begin to approach the limits for the public. From this study it would appear to be safe not to use a lead apron for mini C-arm cases. The surgeons hands are exposed to the most radiation and strategies to reduce this exposure should be pursued

Two discrete legal factors enable the surgeon to treat an injured patient the fully informed, autonomous consent of the adult patient with capacity via civil law; and the medical exception to the criminal law. This article discusses current concepts in consent in trauma; and also considers the perhaps less well known medical exception to the Offences against the Person Act 1861, which exempts surgeons from criminal liability as long as they provide ‘proper medical treatment’.

Aims

The aim of this study was to create artificial intelligence (AI) software with the purpose of providing a second opinion to physicians to support distal radius fracture (DRF) detection, and to compare the accuracy of fracture detection of physicians with and without software support.

Background. Polypharmacy of elderly trauma patients entails further difficulties in addition to the fracture treatment. Impaired renal function, altered metabolism and drugs that are potentially delirious or inhibit ossification, are only a few examples which must be carefully considered for the medication in elderly patients. The aim of this study was to investigate, if medication errors could be prevented by orthogeriatric comanagement compared to conventional trauma treatment. Material and methods. In a superregional traumacenter based on two locations in Munich, all patients ≥ 70 years with proximal femur fracture were consecutively recorded in a period of 3 months. After the end of the treatment the medical records of each patient were analyzed. At the hospital location 1 the treatment was carried out without orthogeriatric comanagement, at the hospital location 2 with this concept (DGU-certified orthogeriatric center). In addition to the basic medication all newly added drugs were recorded as well as changes in the medication plan and also wether treatment was carried out by the geriatrician or the trauma surgeon. Based on the START / STOPP criteria for the medication of geriatric patients, we defined “no-go” drugs with the geriatrician of the orthogeriatric center which should be avoided in the orthogeriatric patient (including benzodiazepines, gyrase inhibitors, NSAID like Ibuprofen with impaired GFR). The statistical analysis was done with the chi-square-test (IBM SPSS Statistics 24). Results and conclusion. A total of 46 patients were included, 37 of them female and 9 male with an average age of 84,5 years (SD±6.8). At the location without a geriatrician (18 patients), a prescription of one or more “no-go” drugs was found in 9 patients, whereas in location 2 (28 patients) only in 3 patients (p=0.003). Besides that, at the location with the geriatrician, a change in the medication was made for 17 patients during their stay in hospital. This shows that with the fixed integration of the geriatrician into the trauma surgical team, errors in the medication of the patients could be significantly more frequent avoided or faster detected and corrected. Although this should not limit the responsibility of the rest of the team, there is no doubt about the importance of the interdisciplinary treatment of elderly trauma patients

Introduction. Orthopaedic and trauma surgeons not infrequently encounter the hallucal interphalangeal joint sesamoid (HIPJS) in irreducible traumatic dislocations. However, patients with the classic triad of plantar keratoma beneath a hyperextended interphalangeal (IP) joint associated with stiffness of the first metatarsophalangeal joint tend to present to podiatrists rather than orthopaedic surgeons. Methods. We present our experience with the HIPJS following first metatarsophalangeal joint (MTP1) arthrodesis in 18 feet of 16 women, aged 42 to 70 years old. Where CT scan was available, volume of the HIPJS was determined using Vitrea Software. Results. Two groups of patients were identified. Group 1 consisted of 12 feet in 11 women, who developed a painful keratoma beneath a gradually hyperextending IP joint of the great toe, at varying intervals (range 6 to 75 months) following MTP1 arthrodesis. Group 2 comprised 6 feet in 5 women who had undergone MTP1 arthrodesis but reported no symptoms in relation to an undetected and/or recognized, but unexcised HIPJS (range 15 to 97 months). We found no difference in average size of the HIPJS between Groups 1 and 2 (190.42 mm. 3. and 196.47 mm. 3. , respectively). Clinically, all toes had been fused in good position and no difference existed in the post-operative angle subtended by the proximal phalanx of the arthrodesed big toe with the first metatarsal between the 2 groups.
