Special Issue Information

Dear Colleagues,

The field of orthopaedic and trauma surgery has a rich history of continuous innovation and improvement in patient care. Over the years, advances in surgical techniques and rehabilitation protocols have transformed the management of musculoskeletal conditions. Recent developments, particularly in arthroscopic procedures and joint replacement, have set new standards in the field and underline the importance of ongoing clinical research.

This Special Issue aims to explore the latest findings in clinical research, with a focus on improving surgical outcomes and patient recovery in orthopaedics and trauma surgery. We aim to capture a wide range of perspectives, from minimally invasive techniques to comprehensive trauma management, to ensure a holistic view of today's orthopaedic challenges.

The cutting-edge research featured in this issue will address the latest advances in hip arthroscopy and hip arthroplasty, including innovative techniques, new implant designs and rehabilitation strategies. We encourage submissions that highlight not only the clinical efficacy but also the integration of technology and personalised medicine in improving patient outcomes.

We welcome original research articles, reviews and case studies that contribute to our understanding of these evolving topics. By fostering a collaborative exchange of knowledge, we hope to advance the field of orthopaedics and trauma surgery, ultimately benefiting patients worldwide.

Background and Objective: The use of computed tomography (CT)-based navigation systems has been shown to improve surgical accuracy in total hip arthroplasty. However, there is limited literature available about the application of CT-based navigation systems in severe hip dysplasia. This study aimed to evaluate the accuracy of a CT-based navigation system in patients with severe hip dysplasia using three-dimensional (3D)-printed bone models. Methods: 3D-printed bone models were generated from CT data of patients with severe hip dysplasia (Crowe type II, 10 hips; type III, 10 hips; and type IV, 10 hips). The accuracy of automatic segmentation, success rate, point-matching accuracy across different registration methods, and deviation values at reference points after registration were assessed. Results: For the combined cohort of Crowe II, III, and IV cases (n = 30), the Dice Similarity Coefficient and Jaccard Index were 0.99 ± 0.01 and 0.98 ± 0.02, respectively. These values indicate a high level of segmentation accuracy. The “Matching with true and false acetabulum + iliac crest” method achieved a 100% success rate across all groups, with mean deviations of 0.08 ± 0.28 mm in the Crowe II group, 0.12 ± 0.33 mm in the Crowe III group, and 0.14 ± 0.50 mm in the Crowe IV group (p = 0.572). In the Crowe IV group, the anterior superior iliac spine deviation was significantly lower using the “Matching with true and false acetabulum + iliac crest” method compared to the “Matching with true and false acetabulum” method (0.28 ± 0.49 mm vs. 3.29 ± 2.56 mm, p < 0.05). Conclusions: This study demonstrated the high accuracy of automatic AI-based segmentation, with a Dice Similarity Coefficient of 0.99 ± 0.01 and a Jaccard Index of 0.98 ± 0.02 in the combined cohort of Crowe type II, III, and IV cases (n = 30). The matching success rate was 100%, with additional points on the iliac crest, which improved matching accuracy and reduced deviations, depending on the case. Full article

Background and Objectives: Intertrochanteric fractures of the femur are common in the elderly due to the increase in longer life expectancy. However, unstable intertrochanteric fractures in the elderly population were still a significant concern for the postsurgical period after total hip arthroplasty (THA). This study aimed to compare the demographics, operative time, dislocation rate, and length of stay of the novel interfragmentary technique (IFT) and the conventional posterolateral approach (CPA) for unstable intertrochanteric femoral fractures treated with THA in the elderly. Materials and Methods: This retrospective study investigated community-dwelling elderly patients with type III, IV, and V unstable femoral intertrochanteric fractures according to the Evans–Jensen classification, treated with THA by a well-experienced single surgeon. The patients were separated into IFT (n = 74) and CPA (n = 67) groups. Patient demographics (age, gender, and body mass index), total surgical duration, dislocation rates, length of stay and follow-up, and complication rates were recorded. Results: The mean age was 80.37 years in the IFT and 80.14 in the CPA groups (p = 0.838). Body mass index, gender, complication, and revision rates did not differ between groups (p > 0.05). The mean follow-up of the IFT group was 4.15 years, and 10.25 years in the CPA group (p = 0.001). Total surgical duration was comparable, with 69.98 min in the IFT group and 69.55 min in the CPA group (p = 0.697). The dislocation rate was 2.7% (n = 2) in the IFT group and 9% (n = 6) in the CPA group (p = 0.109). The mean length of stay was 66.97 h in the IFT group and 67.83 h in the CPA group (p = 0.729). Conclusions: The interfragmentary surgical technique, a novel technique for unstable intertrochanteric fracture surgery, shows promising clinical outcomes. Preserving the short rotator muscles and posterior capsule utilizing the novel IFT can be advantageous for the risk of dislocation without increasing surgical duration. It can be concluded that performing THA using IFT emerges as a practical and viable procedure for treating unstable intertrochanteric fractures in elderly patients. Full article

Background and Objectives: The superficial femoral artery (SFA) can be injured during an intramedullary femoral nailing procedure with proximal and distal cross fixation, performed for proximal femoral fractures and intertrochanteric fractures. The aim of this study was to determine the safe and dangerous zones for the SFA during operative interventions on the femoral body in Turkish society and to define the relationship of these zones with femur length and sex. Materials and Methods: Using a computed tomography angiography, the relationship between the SFA and the medial shaft of the femur was examined in 160 limbs of 80 patients. The upper and lower cut points of the medial part of the SFA in the sagittal plane were defined. The distance of these points to the adductor tubercle was measured and the ratio of this value to the femur length was calculated. Results: The average distance of the SFA to the adductor tubercle in women was 214.2 ± 25.9 mm at the anterior border of the femur, while in men it was 229.8 ± 26.2 mm (p = 0.000). The danger zone length was 85 mm in women and 102 mm in men, and the difference was statistically significant (p = 0.000). The average distance of the SFA to the adductor tubercle at the anterior border of the femur was 223.1 ± 27.3 mm, the average femur length was 374.9 ± 30.2 mm, and a moderate correlation was found between them (r = 0.568). Conclusions: When determining the intraoperative danger zone using anatomical reference points in surgical approaches to the femur, variables such as sex and femur length should not be ignored.

Background and Objectives: The objective of the study was to evaluate the epidemiology of slope-related accidents in a high-volume trauma center during the winter season. In addition, this study aims to analyze patient-related, equipment-related, and environment-related characteristics. Materials and Methods: A questionnaire containing 22 items was distributed to all adult patients admitted to the emergency department of the Brixen Hospital (Italy) during the 2023/24 winter season because of a ski/snowboard-related injury. Results: The final database included 579 questionnaires from 579 patients who ultimately entered the study: 285 were females and 294 were males. The analysis of risk factors for fractures revealed that patients with fractures were generally older (50.7 ± 16.0 years) compared to those without fractures (45.4 ± 17.2 years, p = 0.0021). Thirty-six percent of injuries were considered as joint sprain/ligament strain: patients in this group were younger (45.5 ± 16.2 years) compared to all patients (48.3 ± 17.3 years, p = 0.0151). Conclusions: In conclusion, this study identified significant risk factors associated with skiing and snowboarding injuries. Fractures were more common among older and more experienced skiers, particularly those who described themselves as experts. Ligamentous distortions were more common among younger and less experienced skiers. Fatigue is generally underestimated, and the general physical preparation is often lacking for sports like skiing and snowboarding. Additionally, the absence of significant correlations between weather conditions, snow quality, equipment type, and the difficulty of the slope with injury risk suggests that individual factors such as age and skill level are more critical determinants of injury risk than environmental or equipment-related factors.
