“Tension band wiring first” —an easy, fast and reproducible technique to reduce patellar fractures, a retrospective comparative study with traditional reduction technique

ObjectiveTo evaluate intraoperative and early postoperative clinical outcomes using the “tension band wiring first technique” to reduce C type patellar fractures.MethodsSixty-four patients with C type fractures were enrolled in this study. Thirty-four patients underwent open reduction and internal fixation (ORIF) surgeries using the traditional reduction technique by pointed clamps (TRT group). The other thirty patients received the patellar fracture reduction using the “Tension band wiring first technique” (TBWFT group). All patellar fractures were treated with a cable tension band and a cerclage cable. The duration of intraoperative procedure and X-ray exposure times were recorded. All patients were followed up at 1, 3, 6, and 12 months. Bone union time was recorded. The articular surface steps of the patellas were measured. After surgery, range of motion (ROM) of the knee, and complications were evaluated, and patellar function was evaluated using the Lysholm knee scores and Böstman scores.ResultsWhen compared to TRT group, the “Tension band wiring first technique” significantly reduced the intraoperative time and X-ray exposure times and tended to reduce the articular surface steps, though without statistical significance. In the two groups, there was no significant difference in bone union time, ROM, complications and patellar function.ConclusionThe utilization of “Tension band wiring first technique” proved to be a straightforward, expeditious, and reproducible technique for reducing patellar fracture in comparison to the conventional reduction technique utilizing pointed clamps. Further studies are required to ensure the generalizability of these findings to additional patient populations at other institutions.

Clinical Management, Prognosis, and Outcomes of Bilateral Acetabular Fractures: A Case Report

Background: Bilateral acetabular fractures are a rare type of acetabular fracture, and due to the scarcity of information regarding these types of fractures, managing bilateral acetabular fractures presents significant challenges. We presented a 25-year-old man with bilateral acetabular fractures (left transverse fracture of the acetabulum and right posterior column fracture of the acetabulum) secondary to severe trauma following a road accident with no other pelvic damage. Case Report: Because the displacement was more on the patient's left side (although the patient's pain was more on the right side), the open reduction and internal fixation (ORIF) surgery was first performed on the left side, and secondary ORIF surgery was performed on the right side, under general anesthesia with Kocher-Langenbeck approach for both sides. Conclusion: Due to the increase in road traffic accidents (RTAs) and improper safety of cars, especially in developing countries, this type of fracture may be repeated in the future, and regarding the complexity and comorbidities associated with this type of fracture, the high experience of the surgeon and detailed investigations are required to achieve successful results.

Outcomes of open reduction for hip dislocations in children with connective tissue disorders.

While children with hypermobility and/or ligamentous laxity due to coexisting connective tissue disorders might be expected to have worse outcomes after open reduction for hip dislocations, there is minimal prior research on this topic. All open reduction surgeries for hip dislocations performed at a single urban, tertiary-care children's hospital from 2009 to 2023 were reviewed retrospectively. Those with connective tissue disorders secondary to a diagnosed syndrome or genetic disorder were included. Patients with <1 year of follow-up or hip instability in the setting of Trisomy 21 were excluded. Clinical and radiographic data was collected. Instances of re-dislocation, proximal femoral growth disturbance, residual acetabular dysplasia, and arthrofibrosis were recorded. Twenty-three hips (15 patients) were included. Mean age at the time of surgery was 19.6 months (Range: 8.2-36.0 months), and mean follow-up was 4.3 years. The most common connective tissue disorder condition included was Ehlers-Danlos syndrome (13%). A majority of open reductions were performed via an anterior approach (96%). Seven hips (30%) underwent a concomitant pelvic osteotomy without femoral osteotomy and seven hips (30%) underwent both pelvic and femoral osteotomies. Twenty-two hips (96%) were International Hip Dysplasia Institute grade 1 at the final follow-up. Re-dislocation occurred in four hips (17%); eight hips (35%) demonstrated residual acetabular dysplasia, five hips (22%) demonstrated proximal femoral growth disturbance, and nine hips (39%) developed stiffness postoperatively. Patients with connective tissue disorders and ligamentous laxity have comparable rates of residual acetabular dysplasia, proximal femoral growth disturbance, and (surprisingly) stiffness as typical developmental dysplasia of the hip following open hip reduction surgery. Although the re-dislocation rate in the connective tissue disorders group was approximately 2-3 times higher, the difference did not reach statistical significance. Given that the study was limited by a low sample size, however, it is possible that the findings of no difference in residual acetabular dysplasia and proximal femoral growth disturbance were potentially due to a lack of power.

Recovery of the Infraorbital Nerve Following Open Reduction and Fixation Surgery of Zygomaticomaxillary Complex Fractures-A Prospective Cohort Study Based on Quantitative Sensory Testing.

This study aimed to assess the sensory function of the infraorbital nerve in patients with fractures of the zygomatic complex who underwent open reduction and internal fixation at different time points using quantitative sensory testing, which was established by the German Neuropathic Pain Research Network, comprising a 7-item mechanical and thermal sensory test. A total of 21 patients (age range 17-46y, 14 males) with unilateral zygomatic complex fractures were included. Quantitative sensory testing was conducted before the operation and at 1 week, 3 months, and 6 months operatively, with cold detection threshold, warmth detection threshold, cold pain threshold, heat pain threshold, mechanical detection threshold, mechanical pain threshold, pressure pain threshold, and vibration detection threshold being measured in bilateral infraorbital regions. Notable changes in sensitivity were observed in all values except for the mechanical pain threshold. In the majority of patients with zygomaticomaxillary complex fractures, infraorbital hypoesthesia was significantly improved within 3 months postoperatively, and almost complete recovery could be achieved by 6 months postoperatively.

A National Database Analysis: Does Cold Weather Affect the Surgical Intervention Rate for Developmental Dysplasia of the Hip in Children Under Five Years?

Background Cold weather in the first few months of life may increase the risk of a late diagnosis of developmental dysplasia of the hip (DDH). Early detection of DDH can often be treated non-surgically. The purpose of this study is to observe whether the rates of surgical intervention for DDH differ based on average outdoor temperatures in the winter months. Methods A retrospective observational study of DDH patients diagnosed from 2010 to 2021 was conducted using a national administrative database. Five geographic regions were defined based on the average temperatures in the coldest quarter of the year. The rates of DDH-related surgeries were compared across these temperature regions. Results A total of 55,911 patients ≤5 years old with a DDH diagnosis from 2010 to 2021 were identified in the database. When compared to the warmest region (Group 5), the coldest region (Group 1) had higher rates of open reduction (4.59% vs. 2.06%, p<0.001), adductor tenotomy (6.95% vs. 2.91%, p<0.001), femoral osteotomy (5.75% vs. 2.04%, p<0.001), pelvic osteotomy (5.27% vs. 2.04%, p<0.001), and total DDH surgeries (11.42% vs. 5.03%, p<0.001). Conclusion Children living in states with an average winter temperature of -6.17°C had an increased likelihood of requiring surgical intervention for DDH within the first five years of life.

Elbow Reconstruction with Megaprosthesis: An Effective Strategy for Salvage Surgery in Trauma Patients.

Delayed fracture healing can have devastating functional consequences, including pseudoarthrosis. Many factors can contribute to delayed healing, including decreased vascularity, micro-motion at the fracture site, large fracture gaps, multiple traumas at the same site, compromised metabolic status, surgical complications, and other conditions. A 61-year-old female patient was referred to our hospital with left distal humeral pseudarthrosis, accompanied by chronic pain and disability. Two years prior, the patient suffered a traumatic incident. At another medical facility, the patient underwent open reduction and internal fixation surgery with simultaneous ulnar nerve transposition. She showed favorable postoperative recovery. Unfortunately, approximately one year later, the patient sustained a second trauma to the same arm. This led to peri-implant fracture and post-traumatic aseptic degradation of the osteosynthesis system which was subsequently removed. Twelve months after the last surgery, the patient was referred to our hospital and, after thorough consideration of the therapeutic options, we decided to perform left elbow arthroplasty with left distal humeral reconstruction by using Zimmer's Comprehensive Segmental Revision System. This approach is generally reserved for tumors, and only a handful of cases of megaprostheses for non-tumoral indications have been previously reported. The surgery and perioperative care of our patient were optimal, there were no complications, and the patient recovered arm functionality following rehabilitation.

Imaging risk factors for predicting postoperative complications of intramedullary nailing for tibial fracture

ObjectiveThe objective of this study was to analyze the ratio of fracture site diameter to tibial isthmus diameter (TFI ratio) as a predictor of postoperative complications, including malunion and delayed union, after tibial intramedullary nailing for middle and lower tibial fractures.MethodsData were collected from all adult patients older than 20 years of age who underwent tibial intramedullary nailing for middle and lower tibial fractures between January 2015 and January 2023 and were followed up for at least 1 year. Diabetes history, smoking history, fracture type, injury mechanism, surgical method, surgical approach, diameter of the medullary cavity at the fracture site, and diameter of the tibial isthmus were recorded. Logistic regression analysis was used to determine the variables affecting the occurrence of complications. The TFI ratio was used to calculate the sensitivity and specificity of the parameters, and ROC curves were generated to establish TFI ratio thresholds for predicting complications.ResultsA total of 123 patients with middle and lower tibial fractures were treated with intramedullary nails. The mean age of the patients was 43.72 years (range, 21–81 years); 89 were males, and 34 were females. Univariate logistic regression analysis showed that fracture type, open reduction surgery, superior patellar approach, and TFI ratio were significantly correlated with postoperative complications after intramedullary nailing of a tibial fracture. Multivariate logistic regression analysis showed that the TFI ratio was an independent risk factor for complications (P = 0.001*). By using the TFI ratio as a predictor of complications, an ROC curve was generated to establish a threshold. The ROC curve showed that a TFI ratio ≥ 1.31 had a sensitivity of 0.89, a specificity of 0.71, and an area under the ROC curve of 0.82 for predicting complications.ConclusionsThe results of this study suggest that a wider intramedullary diameter and a shorter fixed length at the fracture site are associated with a higher incidence of complications after tibial intramedullary nailing. The TFI ratio may be used as a reliable parameter for predicting complications after such surgery. In patients with a high TFI ratio (≥ 1.31), additional reduction and fixation techniques may be needed to obtain and maintain fracture reduction.

Preoperative Gallows traction as an adjunct to hip open reduction surgery: Is it safe and is it effective?

Traction is used at our hospital before open reduction in infants with developmental dysplasia of the hip. Theoretically, it reduces soft-tissue tension, allowing an easier surgical reduction and therefore lower surgical complications. Owing to extended hospital stays, potential complications, and lack of evidence, the use of traction has decreased. This study aims to quantify whether traction is safe and whether it has any demonstrable effect. The perioperative course of 80 patients undergoing preoperative traction and hip open reduction were reviewed. The height of hip dislocation was classified using the International Hip Dysplasia Institute classification system on both radiographs taken before and after traction. Any complications related to traction were recorded, along with the requirement for femoral shortening osteotomies, incidence of re-dislocation, and longer-term rate of avascular necrosis. Traction lowered the resting position of the majority of hips, with the median International Hip Dysplasia Institute grade before traction improving from 4 to 3, a statistically significant improvement (p < 0.00001). There were no neurovascular complications. Two babies were complicated with broken skin sores; however, surgery still progressed uneventfully. Zero hips in the cohort required femoral shortening osteotomies to achieve a tension-free reduction, and the re-dislocation rate was 0%. However, 96% of hips were Severin 1 or 2 at 6-year follow-up. Notably, 1 week of preoperative traction significantly improves the resting position of the hip in high dislocations. It is safe when used in infants weighing <12 kg, and subsequent surgical outcomes are excellent, thus supporting its use ahead of developmental dysplasia of the hip open reduction surgery. Level IV.

Utilizing generative conversational artificial intelligence to create simulated patient encounters: a pilot study for anaesthesia training.

Generative conversational artificial intelligence (AI) has huge potential to improve medical education. This pilot study evaluated the possibility of using a 'no-code' generative AI solution to create 2D and 3D virtual avatars, that trainee doctors can interact with to simulate patient encounters. The platform 'Convai' was used to create a virtual patient avatar, with a custom backstory, to test the feasibility of this technique. The virtual patient model was set up to allow trainee anaesthetists to practice answering questions that patients' may have about interscalene nerve blocks for open reduction and internal fixation surgery. This tool was provided to anaesthetists to receive their feedback and evaluate the feasibility of this approach. Fifteen anaesthetists were surveyed after using the tool. The tool had a median score [interquartile range (IQR)] of 9 [7-10] in terms of how intuitive and user-friendly it was, and 8 [7-10] in terms of accuracy in simulating patient responses and behaviour. Eighty-seven percent of respondents felt comfortable using the model. By providing trainees with realistic scenarios, this technology allows trainees to practice answering patient questions regardless of actor availability, and indeed from home. Furthermore, the use of a 'no-code' platform allows clinicians to create customized training tools tailored to their medical specialties. While overall successful, this pilot study highlighted some of the current drawbacks and limitations of generative conversational AI, including the risk of outputting false information. Additional research and fine-tuning are required before generative conversational AI tools can act as a substitute for actors and peers.

The Current Concept and Evidence-Based Practice in the Base of the First Metacarpal Bone Fracture.

Repetitive instances of sudden injuries to the first metacarpal bone can affect thumb movement. These injuries typically occur after vertical impact to the thumb. The treatment for these injuries should focus on restoring the structure and biomechanics of the trapeziometacarpal joint, with surgery being recommended for optimal results. Bennett's fracture involves the bifurcation of the bone into two distinct fragments, characterized by a smaller fragment and a larger counterpart. Rolando fracture is associated with a fracture of the base of the first metacarpal bone, typically divided into three parts. An extra-articular fracture involves the metacarpal bone of the thumb. Conservative treatment outcomes have been found to be unsatisfactory when the fracture is displaced. Therefore, surgery methods such as minimally invasive surgery, open reduction, and arthroscopic surgery have been proven to be effective. Surgical techniques for bone procedures include pin fixation, direct screw fixation, indirect screw fixation, and mini-plate fixation. Additionally, the prognosis of this condition depends on the ability to restore joint mobility during rehabilitation.

Neglected Anterior Shoulder Joint Dislocation Treated with Open Reduction and Latarjet Procedure: A Case Report

INTRODUCTION:The joint dislocation is most commonly occurring in shoulder joint. There are two types of dislocation which is anterior and posterior joint dislocation. Most of the case that brings patients to the clinic was the anterior subtypes dislocation and it needs an immediate treatment. Chronic anterior shoulder joint dislocation is a rare case of anterior joint dislocation in orthopaedics where the dislocation of the joint has remained dislocated for three weeks. CASE PRESENTATION:A 49-year-old with left shoulder deformity he came to outpatient department of Orthopaedics with chief complaint pain when moving the left shoulder region for 6 months ago. He went for traditional massage treatment, but pain on shoulder still persisted and still deformed. Patient diagnosed with neglected anterior shoulder dislocation for 6 months, open reduction and Latarjet surgery was done to manage the case. Follow up the patient for 3 months as outpatient and there is no pain or recurrent dislocation. DISCUSSION:Chronic anterior shoulder joint dislocation is an unusual case for Orthopaedic surgeons to encounter. Latarjet would bring stability by ‘triple effect’ and it is more familiar for the surgeon than remplissage procedure CONCLUSION:Neglected anterior shoulder joint dislocation was one of rare case in Orthopaedics where there is no specific treatment for the dislocation but with open reduction and Latarjet surgery, there was a higher effectiveness for stability and lower recurrence rate Keywords: Neglected anterior shoulder dislocation, Latarjet procedure, open reduction

Treatment of Non-Union Distal Femoral Fractures -A Case Study

Distal femoral fractures are a type of fracture that occurs in the lower part of the femur, near the knee joint. These fractures are relatively rare, comprising only 0.4% of all fractures and 4-6% of femoral fractures. Distal femur fractures can be a serious injury that can lead to long-term complications, including non-union. Non-union is a condition in which a bone fails to heal after a fracture, leading to persistent pain, limited mobility, and other complications. Non-union of the distal femur can be particularly challenging to treat and may require a comprehensive approach that involves surgical intervention, rehabilitation, and close monitoring. A 56 years-old male patient presented with a broken plate of the distal femur in the right foot and was enrolled in the study. At the time of admission, the blood pressure and pulse of the patients were 110/70 mmHg and 80 bpm respectively. The patient was instructed to follow preoperative protocol before the surgery, which included nothing from the mouth (NPO) from midnight until the completion of the surgery. In this case study, open reduction and internal fixation (ORIF) surgery was performed to fix the fractures of the distal femur. After a successful surgery, patients are often prescribed different types of medications to manage pain, prevent infection, and promote healing. The patient was encouraged to follow the dietary recommendations as closely as possible. Physical therapy is often an important component of postoperative care and can help patients recover from surgery more quickly and effectively. The patient's outcome was excellent, with fewer complications. The patient with distal femur fractures resulted in a tremendous outcome after successfully operating with minimal complications, as reported in this current case study.

Endovascular repair of a ruptured axillary artery during open reduction of the shoulder dislocation with humerus fracture

Abstract Axillary artery injury secondary to shoulder dislocation with humerus fracture is rare. Rupture of the axillary artery during open reduction is extremely rare. Here, we report about a rare case of a ruptured axillary artery during an open reduction for shoulder dislocation with humerus fracture. A 58-year-old man with left shoulder pain because of a fall after alcohol consumption was diagnosed as having left shoulder dislocation with a humerus fracture. He underwent open reduction surgery. During the procedure, bleeding was observed, and further examination through angiography revealed an ruptured axillary artery. To address this urgent situation, stent grafts were promptly deployed retrogradely from the brachial artery. The postoperative course was uneventful, except for brachial plexus palsy. In the emergent setting, endovascular repair is an efficient alternative to conventional open surgery for controlling bleeding when a ruptured axillary artery occur during open reduction for shoulder dislocation.

Translated article] Subtalar dislocations: Analysis of a case series. Our urgent treatment algorithm

Introduction and objectivesSubtalar dislocations are a rare entity (<1%) in traumatic foot injuries. There is a loss of anatomical relationship between the talus, calcaneus and scaphoid. There are only small-published series. Material and methodsWe present a series of patients (N=13) with subtalar dislocations in which a descriptive analysis of the main epidemiological, clinical and radiological variables was carried out, from which an urgent treatment algorithm is proposed. Cases with fractures of the neck of the talus, body of the calcaneus, or isolated Chopart fracture-dislocations were excluded. ResultsThe median age was 48.5 years with a predominance of males (69.23%). Five patients suffered falls or sprained ankles and the other eight suffered high-energy mechanisms. The medial dislocations (nine) predominated over the lateral ones (four). In addition, four patients presented open dislocations, two of them type IIIC that required amputation. CT scans were requested in 76.93% of patients and 10 presented associated bone lesions of the foot. Open reduction surgery was performed in all open lesions and in one case in which closed reduction failed. Five patients required a delta-type external fixator. Subchondral articular sclerosis was observed in 77.77% of cases; although only one required subtalar arthrodesis. ConclusionsSubtalar dislocations are a traumatic emergency that require early reduction and subsequent immobilisation. Transarticular temporary external fixation is a good immobilisation option in open dislocations. They are serious lesions with a high probability of early osteoarthritis.

The effect of local injection of bupivacaine with and without fentanyl at the operative site in mandibular open reduction on acute pain intensity and opioid requirement: a randomized clinical trial.

The aim of this study is to investigate the effects of bupivacaine local injection with and without fentanyl at the operative site in mandibular open reduction surgeries on the severity of acute pain and the need for opioids. This randomized clinical trial, age-sex-matched double-blind study included 44 patients with isolated mandibular fractures who would be candidates for open reduction. They were divided into two groups (intervention using fentanyl and control not using fentanyl). In both groups, the amount of opioid used, hemodynamic indices, oxygen saturation, and pain intensity were collected based on the Visual Analogue Scale (VAS) every 4 h for 24 h. As for basic and demographic variables such as gender, age, ASA class, and duration of surgery (P > 0.05), there was neither a significant difference between the two groups nor was there any difference in nausea and vomiting and subsequent anti-nausea medication (P > 0.05). The need for a post-operative opioid in the bupivacaine + fentanyl group (13.6%) was significantly less than in those who received only bupivacaine (45.5%) (P < 0.05). Changes in pain scores over time were significantly different in the two groups, and bupivacaine + fentanyl reduced pain more than bupivacaine (P < 0.05). However, over time, there was no significant difference between the two groups in terms of changes in oxygen saturation, heart rate, systolic blood pressure, and diastolic blood pressure (P > 0.05). The addition of fentanyl to bupivacaine for supraperiosteal injection in the open reduction surgery site reduces post-operative pain in the first 24 h and reduces the need for opioids without causing complications such as nausea and vomiting.

A clinical prediction model for predicting the surgical site infection after an open reduction and internal fixation procedure considering the NHSN/SIR risk model: a multicenter case-control study.

Surgical site infection (SSI) is one of the most common surgical-related complications worldwide, particularly in developing countries. SSI is responsible for mortality, long hospitalization period, and a high economic burden. This hospital-based case-control study was conducted in six educational hospitals in Tehran, Iran. A total of 244 patients at the age of 18-85 years who had undergone open reduction and internal fixation (ORIF) surgery were included in this study. Among the 244 patients, 122 patients who developed SSIs were selected to be compared with 122 non-infected patients used as controls. At the second stage, all patients (n = 350) who underwent ORIF surgery in a hospital were selected for an estimation of the standardized infection ratio (SIR). A logistic regression model was used for predicting the most important factors associated with the occurrence of SSIs. Finally, the performance of the ORIF prediction model was evaluated using discrimination and calibration indices. Data were analyzed using R.3.6.2 and STATA.14 software. Klebsiella (14.75%) was the most frequently detected bacterium in SSIs following ORIF surgery. The results revealed that the most important factors associated with SSI following an ORIF procedure were found to be elder age, elective surgery, prolonged operation time, American Society of Anesthesiologists score of ≥2, class 3 and 4 wound, and preoperative blood glucose levels of >200 mg/dl; while preoperative higher hemoglobin level (g/dl) was found to be a protective factor. The evidence for the interaction effect between age and gender, body mass index and gender, and age and elective surgery were also observed. After assessing the internal validity of the model, the overall performance of the models was found to be good with an area under the curve of 95%. The SIR of SSI for ORIF surgery in the selected hospital was 0.66 among the patients aged 18-85 years old. New risk prediction models can help in detecting high-risk patients and monitoring the infection rate in hospitals based on their infection prevention and control programs. Physicians using prediction models can identify high-risk patients with these factors prior to ORIF procedure.

Functional Outcomes of Neglected Elbow Dislocation Treated with Double Approach Surgery.

Neglected elbow dislocation is common in developing countries. The chronic nature of the disease results in a level of complexity that makes treatments and outcomes contradictory. Several treatment methods have been described for neglected elbow dislocations. The goal of this study was to evaluate the results of neglected elbow dislocations treated using the double approach of reduction and K-wire fixation. This series included patients with neglected elbow dislocations who were treated with open reduction using double approaches (medial and lateral incisions) between November 2020 and March 2021. Patients were evaluated for a minimum of 6 months to ascertain functional recovery in accordance with the Mayo Elbow Performance Index (MEPI) and Disability of Arm, Shoulder, and Hand (DASH) score. Nine patients with neglected elbow dislocations were included in the study, with an average delay of 3.44 months. Four patients had an excellent MEPI and five had a good score at the final follow-up, with a mean MEPI score of 86.67. The average DASH score was 36 (31-59). Five patients (55.56%) experienced no pain, but four patients (44.44%) had mild pain, with a range of pain points of 30-45. The motion arc improvement was 60°-100°, with a mean of 74.44°. Almost all of the patients (eight patients, 88.89%) had elbow stability, but one patient had ulnar nerve paresthesia postoperatively. Heterotopic ossificans was associated in 1 patient, and triceps lengthening was needed in 1 patient; both came 5 months later. Open reduction surgery with a double approach offers a good chance of a good result with few side effects and should be considered for all patients who have this condition.
