Active clinical trials for "Fractures, Bone"

The purpose of the study is to compare two common ways of rehabilitating after proximal humerus fractures treated non-operatively.

The purpose of this study is to measure the sensitivity and specificity of ultrasound exam of the hip in diagnosing occult hip fractures.

Over the last months, the Rizzoli Orthopedic Institute in Bologna, Italy, has drained orthopedic urgencies from all other hospitals in the urban and suburban area. In this context urgencies are defined as fractures and primary or metastatic bone lesions with indication to non-deferrable surgery. A subset of these patients tested positive for SARS CoV 2, either before or after the surgical procedure. Anesthesiological clinical management of covid19 cases is complicated by the consequences of the viral infection on respiratory and cardio-vascular systems, renal function and coagulation. Similarly, management of asymptomatic patients is challenging because of the lack of data on possible specific complications. This study will report a snapshot of our early experience on perioperative clinical management of patients undergoing orthopedic surgery in the presence of SARS CoV 2 infection, ascertained or not at the time of surgery.

The purpose of this study was to determine the impact of design on plate position at the level of the distal radius. Six anterior wrist plates design were analyzed relative to the watershed line using the Soong classification. A total of 2723 anterior locking plate fixation cases were analyzed and divided into six groups: Zimmer Biomet, Newclip Technics, Stryker, Synthes, Medartis and Medartis Footprint. The number of plates recorded as Soong grade 0+1 was determined for each design, then compared using the Marascuilo procedure. The Zimmer Biomet and Newclip plates were proximal to the Watershed line significantly more often than those by Synthes and Medartis Footprint. Plate position with the Medartis design was significantly more proximal to the Watershed line compared to its companion design, the Medartis Footprint plate. Plate design is a deciding factor when treating distal radial fractures, to avoid impingement when implant removal is not routinely planned.

Acetabulum fractures are complex, relatively rare lesions linked to a more or less good functional prognosis and therefore represent a real surgical challenge. In the literature, it is accepted that surgical delay, among other things, negatively impacts the quality of surgical reduction. However, this reduction must be a major priority since it is one of the factors conditioning the functional result. In our study, we wish to analyze a particular type of fracture, less studied, or with small series, that are the transverse fractures (+/- posterior wall), known for their difficulty of reduction. The reduction is even greater as the fracture line often passes through the acetabular bearing zone, compromising the functional prognosis. The choice of surgical approach for this type of fracture is controversial. More and more, a single approach, usually posterior, without compulsory fixation of the anterior component of the transverse fracture is preferred over the traditional double approach anterior and posterior, and this in particular to reduce the morbidity of this surgery. But this one-size-fits-all approach does not always achieve a good reduction and it is believed that the time to surgery may play a role. If it is accepted that the surgical delay before reduction in osteosynthesis of an acetabular fracture is involved in the quality of the reduction and therefore the functional result in these patients, the question asked is whether this delay should condition the choice of a double approach, anterior and posterior, for this type of fracture (transverse +/- posterior wall). Indeed, with increasing surgical time, the risk of scar tissue formation and early callus increases, making bone fragments less mobile, reduction more difficult and indirect reduction techniques (which are used when single approach is chosen) less efficient. In addition, most of the studies evaluating the quality of reduction of acetabular fractures use a radiographic score, that of Matta. However, it has been shown that the CT scan was more efficient than the x-rays in detecting a residual displacement of the fracture. Also, in this study, we want to analyze the quality of reduction thanks to the scanner, which is rarely done in the literature. This work aims to determine the predictive factors of the quality of reduction of transverse fractures +/- posterior wall of the acetabulum, evaluated on the postoperative CT scan.

The microbiome of 80 orthopedic-device related infection (ODRI) patients treated with antibiotics and 10 healthy controls will be investigated. Samples (blood, stool, saliva, skin-swab) are collected 4x within 6 months. Composition and diversity of the microbiome will be assessed by 16sRNA sequencing, skins swabs are screened for rifampicin-resistant staphylococci onto Mannitol-salt-agar plates supplemented with rifampicin, inflammation markers and antibodies in blood and saliva are monitored to track changes in the immune response. For further analysis patients are assigned to one of two groups: 1) antibiotic therapy including rifampicin and 2) non-rifampicin antibiotic therapy.

Background : Type 1 diabetes is associated with an increased risk of fractures. The mechanisms accounting for this bone fragility are not yet fully understood. The lower bone mineral density (BMD) observed in individuals with type 1 diabetes cannot solely explain the higher fracture incidence. Bone microarchitecture defects significantly contribute to bone fragility. Few studies assessed spine fractures in type 1 diabetes. This cross-sectional multicenter case-control study aims (1) to evaluate the prevalence of asymptomatic vertebral fractures in individuals with type 1 diabetes in comparison to age- and sex-matched healthy controls; (2) to compare individuals with diabetes with vertebral fractures and those without vertebral fracture using clinical, biochemical and radiological parameters.

Children who are born early (pre-term infants) are at increased risk of fractures until the age of 2 years, due to their weak bones caused by several physiological, and environmental factors.There is however little information about the persistence of this increased risk of fractures in childhood. There is also lack of detail in the medical literature about the gestational age at birth of children presenting to hospitals with fractures, the nature of their fractures and the differences in fracture features, if any, between the preterm and term (infants born at 37 weeks and above) children. This information would be especially useful for doctors when deciding if a fracture with no other obvious explanation in a preterm child is caused by an accidental or inflicted injury. This dilemma is complicated by reports that preterm children are more likely to be subjected to abuse as compared to term children. Furthermore, infants less than a year old are more likely to be abused, and this coincides with the time when preterm infants are most vulnerable. Hence it is important to collect information about the physical examination, chemical substances in their blood and x-ray features of fractures in preterm children. Also important to study is whether there are differences in how accidental and inflicted fractures present in term and preterm children, as certain findings in term children might not apply in the context of prematurity. Determining if preterm birth is a major cause for childhood fractures is also especially relevant to the medico legal profession. When there is a suspected inflicted fracture in an ex-preterm child, the outcome could depend on whether prematurity is an adequate explanation for fractures. We would like to collect, study and present detailed information on the differences in causes and patterns of accidental and inflicted fractures in both preterm and term children. This could lend support to medical opinions offered in medico legal proceedings in which child abuse is alleged in preterm infants.

Pelvic ring fractures are common and often the result of high energy trauma but also sometimes of lower energy trauma in older patients. A good classification and description of the fracture is essential to the choice of treatment. The classifications used to describe these fractures are numerous (Tile modified AO, Young and Burgess, Letournel, Rommens) and of a descriptive order more or less depending on the lesion mechanism allowing some to orient the surgical reduction technique. However, none of them helps with the choice of surgical or functional treatment, which is currently based on obvious notions of instability and / or displacement of lesions and, by habit, all different services. In addition, the complexity of these classifications leads to poor reproducibility of these. A new method for analyzing unitary lesions has been developed in the Orthopedic Surgery department of the Paris Saint-Joseph Hospital Group with a rating system which determines the indication according to the score. Teaching this new method of analyzing pelvic ring fractures would simplify decision making between surgical and functional treatment.

This cohort study investigates radiological and clinical outcome after screw osteosynthesis of radial head fractures with associated injuries (such as rupture of the interosseous membrane and collateral ligaments). Interpretation of radiographs 3 and 9 months post- surgery and patient surveys will be analyzed.
