Malalignment in the lower limb structure occurs due to various causes. Accurately evaluating limb alignment in situations where malalignment needs correction is necessary. To create an automated support system to evaluate lower limb alignment by quantifying mechanical tibiofemoral angle (mTFA), mechanical lateral distal femoral angle (mLDFA), medial proximal tibial angle (MPTA), and joint line convergence angle (JLCA) on full-length weight-bearing radiographs of both lower extremities. In this retrospective study, we analysed 404 radiographs from one hospital for algorithm development and testing and 30 radiographs from another hospital for external validation...

BACKGROUND: Arthrofibrosis is a joint disorder characterized by excessive scar formation in the joint tissues. Vitamin E is an antioxidant with potential anti-fibroblastic effect. The aim of this study was to establish an arthrofibrosis rat model after joint replacement and assess the effects of vitamin E supplementation on joint fibrosis. METHODS: We simulated knee replacement in 16 male Sprague-Dawley rats. We immobilized the surgical leg with a suture in full flexion...

PURPOSE: This study aimed to elucidate the characteristics of varus knee deformities in the Japanese population, prevalence of various around knee osteotomy procedures and influence of femoral and tibial bowing. METHODS: Varus knee deformity was defined as a weight-bearing line ratio of <50%. A total of 1010 varus knees were selected from 1814 varus knees with weight-bearing full-length radiographs, obtained at two facilities, based on exclusion criteria...

Monitoring programmes worldwide use biota to assess the "health" of water bodies. Indices based on biota are used to describe the change in status of sites over time, to identify progress against management targets and to diagnose the causes of biological degradation. A variety of numerical stressor-specific biotic indices have been developed based on the response of biota to differences in stressors among sites. Yet, it is not clear how variation in pressures within sites, over what time period, and in what combination has the greatest impact on different biotic groups...

River-floodplain ecosystems play a crucial role in connecting landscape patches through hydrological connectivity, but they are among the most threatened ecosystems. Floodplains provide important habitat for amphibians by connecting aquatic and terrestrial habitats. Modifications to floodplain hydrology can impact amphibian communities, yet few studies have examined amphibian metacommunities in floodplain wetlands.In this study, we assessed patterns in amphibian breeding abundance in one of the largest floodplains of the Danube River, Hungary, relative to hydrological connectivity and multi-scale variables at 30 waterbody sites...

Rhizarthrosis is one of the most common arthritic changes in the hand, which has led to the development of a large number of surgical methods in recent years. In addition to the traditional resection arthroplasty with tendon suspension or interposition, if needed, thumb saddle joint prostheses are being used more and more frequently. However, these are not an option for all patients such as those with severe osteoporosis, severe nickel allergy, insufficient height of the trapezium or STT osteoarthritis. This study examined whether the traditional surgical methods continue to have their "right to exist" or whether they will be replaced by prostheses...

PURPOSE: Total knee arthroplasty (TKA), which has medial pivot and mobile-bearing mechanisms, has been developed and clinically used. However, the in vivo dynamic kinematics of the mobile medial pivot-type TKA (MMPTKA) is unclear. This study analysed the in vivo kinematics of MMPTKA in weight-bearing and nonweight-bearing conditions. METHODS: The study included 10 knees that underwent primary TKA using MMPTKA. After TKA, lateral view radiographs of the knee in full extension, 90° of flexion and passive full flexion were taken under general anaesthesia in the nonweight-bearing condition...

INTRODUCTION: With the increasing incidence of total knee arthroplasty (TKA), there is an expected rise in rate of periprosthetic fractures in the coming years. It is unclear how the outcomes of patients with distal femur fractures (DFF) and a total knee arthroplasty compare to patients of the same age group with native knees (NK). MATERIALS AND METHODS: A retrospective review was completed for distal femur fractures treated with surgical fixation from January 2019-March 2021...

OBJECTIVE: To describe the financial capability (FC) and financial well-being (FWB) of adults living with acquired brain injury (ABI) from a lived experience perspective. DESIGN: People living with ABI completed a 32-item and close others a 22-item anonymous survey using either online or print/mail-in options. SETTING: Responses were collected from adults in the province of Manitoba (Canada) during August-October 2021. PARTICIPANTS: Respondents were adults (18+) living with ABI (n=38) or close others of ABI survivors (n=19)...

BACKGROUND: The tibial tubercle-to-trochlear groove (TT-TG) distance and Insall-Salvati (I/S) ratio are widely used to determine the need for distal realignment in conjunction with medial patellofemoral ligament (MPFL) reconstruction in patients with recurrent patellar dislocation. A TT-TG distance >20 mm and an I/S ratio >1.3 are significant anatomical risk factors for patellar instability. However, these parameters have traditionally been measured using non-weight-bearing (NWB) imaging modalities...

INTRODUCTION AND IMPORTANCE: Obturator hip dislocation and luxatio erecta humeri are two extremely rare injuries. We are reporting a very rare case that involves the association of these two injuries. CASE PRESENTATION: We reported the case of a 34-year-old male who was a victim of a high-energy road accident. Initial examinations showed a right obturator dislocation associated with a left luxatio erecta humeri without vascular-nervous complication. Further examinations have ruled out life-threatening injuries...

BACKGROUND: Posterior tibial slope (PTS) exhibits considerable variability among individuals and is anticipated to influence the accuracy of radiographic measurements related to the knee. Despite this potential impact, there is a lack of prior research investigating how PTS affects the accuracy of these measurements. Therefore, this study aimed to investigate the effect of PTS on the measurement reliability regarding the radiographic parameter of the knee. METHODS: The medical records of patients who took full-length anteroposterior radiographs of the lower limb between January 2020 and June 2022 were evaluated retrospectively...

CASE: We present the case of a 25-year-old man with body mass index of 77 who underwent open reduction internal fixation (ORIF) of a displaced fracture dislocation of the acetabulum after a high-speed motor vehicle accident. Remarkably, he achieved full weight-bearing with minimal hip pain and has returned to independent mobility and meaningful work. CONCLUSION: ORIF of an acetabular fracture in a patient with class III obesity presents many challenges. Positioning, surgical approach, fracture manipulation, and postoperative morbidity and mortality can be managed through interdisciplinary collaboration and preoperative communication...

BACKGROUND: The incidence of all periprosthetic fractures (PPF), which require complex surgical treatment associated with high morbidity and mortality, is predicted to increase. The evolving surgical management has created a knowledge gap regarding its impact on immediate outcomes. This study aimed to describe current management strategies for PPF and their repercussions for in-hospital outcomes as well as to evaluate their implications for the community. METHODS: PIPPAS (Peri-Implant PeriProsthetic Survival Analysis) was a prospective multicentre observational study of 1387 PPF performed during 2021...

The incidence of deep surgical site infections following high tibial osteotomy (HTO) ranges between 0.4 to 4.7%. It is a severe complication with a high risk for poor clinical outcome. The aim of this study was to proof that a salvage algorithm for infected HTO with unstable bone situation leads to an infection-free status and bone union of the osteotomy and that correct limb alignment can be restored with good knee function.The study included seven patients with peri-implant infections following HTO. Infections occurred 83 ± 58...

PURPOSE: Infected nonunion of the tibia with a large segmental bone defect is a complex and challenging condition for the patient and surgeon. This scoping review was conducted to identify existing evidence and knowledge gaps regarding this clinical scenario. Secondly, the objective of this study was to search for a valid recommendation on the optimal treatment. METHODS: A comprehensive search was conducted in the bibliographic databases: PubMed, Embase.com, and Web of Science Core Collection...

PURPOSE: We identified limb misalignment by applying personalized axial force while the limb was in a supine position to mimic a standing posture. This study aimed to confirm the accuracy of evaluating lower limb alignment using supine weight-bearing CT scanograms. METHODS: We prospectively compared measurements of the weight-bearing line ratio (WBL), hip-knee-ankle (HKA) angle, and joint convergence angle (JLCA) in 46 sets of supine weight-bearing CT scanograms with those obtained from full-length standing anteroposterior lower extremity radiographs...

PURPOSE OF REVIEW: Transfusion therapy commonly supports patient care during life-threatening injury and critical illness. Herein we examine the recent resurgence of whole blood (WB) resuscitation for patients in hemorrhagic shock following trauma and other causes of severe bleeding. RECENT FINDINGS: A growing body of literature supports the use of various forms of WB for hemostatic resuscitation in military and civilian trauma practice. Different types of WB include warm fresh whole blood (FWB) principally used in the military and low titer O cold stored whole blood (LTOWB) used in a variety of military and civilian settings...

OBJECTIVE: Dual-plate fixation was thought to be the gold standard for treating complicated bicondylar tibial plateau fractures, yet it was found to be hard to accommodate the posterior column in three-column fractures. Currently, column-specific fixation is becoming more and more recognized, but no comprehensive investigation has been performed to back it up. Therefore, the objective of this study was to validate the importance of posterior column fixation in the three-column tibial fractures by a finite element (FE) analysis and clinical study...
