Intramedullary Resorbable Fixation System Versus K-wire for the Treatment of Lesser Toe Deformities...
Hammer ToeSurgery2 moreHammertoe deformity is one of the most common deformities in the foot and is characterized by dorsiflexion of the proximal phalanx at the metatarsal-phalangeal joint and a plantarflexion of the middle phalanx at the proximal interphalangeal joint. Surgical intervention for this type of deformity is indicated when the symptoms progress and conservative treatments are not enough, that is, when we are faced with a rigid painful deformity.Arthrodesis of the proximal interphalangeal joint temporarily fixed with a Kirschner wire is the most commonly used techniques. Therefore, intramedullary fixation with a PLLA needle may be a good alternative. The use of biomaterial is gaining relevance in foot surgery, with polylactic acid being the most widely used due to its strength. Its total biodegradation requires a time of 16-24 months. No cases of foreign body reaction have been described with this type of osteosynthesis material, due to its characteristics similar to those of bone. Its only drawbacks are that it increases the complexity of the technique and that it increases the cost of the procedure. Being a flexible needle, it allows to leave a functional intraoperative claw. It maintains the functionality of the distal interphalangeal joint and carries a lower risk of infection by carrying osteosynthesis material on the outside. The purpose of the present study is to prospectively collect clinical and radiographic outcomes of operative correction of hammertoe deformity using a fixation system of intramedullary device of polylactic acid versus a kirschner wire.

NIRS Guidance Trail in Children's Heart Surgery
Heart DefectsCongenitalHeart surgery in young children involves some risks. This study looks at a new type of monitor that may reduce these risks. Near Infrared Reflectance Spectroscopy (NIRS) aims to measure if enough blood reaches vital organs in the body. The investigators goal is to see if this shows problems developing sooner than usual. The investigators do not know at this time if they can improve the blood supply to the vital organs. The investigators main aim is to see which responses work the best. The NIRS monitor is approved by the U.S. Food and Drug Administration (FDA). The investigators will also follow the progress of recovery after surgery in the Cardiac Intensive Care Unit (CICU). This will find out if using the NIRS monitor improves the outcome for children.

Anomalies of Dense Platelet Granules
Spontaneous Induced Unexplained HaemorrhagicThe study aims to know the overall prevalence of granular deficits and their breakdown by type (anomaly of number, content or secretion) in a population of patients with hemorrhagic symptomatology after exclusion of other known causes. This study consists also to evaluate the association between the presence of a deficit in dense granules and (1) the intensity of the hemorrhagic phenotype (hemorrhagic score) (2) the nature of hemorrhages (post-operative, spontaneous, atypical...) -Evaluate the association between the type of deficit in dense granules and (1) the intensity of the hemorrhagic phenotype (hemorrhagic score) (2) the nature of hemorrhages (post-operative, spontaneous, atypical...)

Surgical Treatment of Spinal Deformity With Sagittal Imbalance Using Patient-specific Rods: A Multicenter,...
Spinal Deformity With Sagittal ImbalanceLumbar degenerative diseases (LDD) are an increasingly common condition affecting millions of patients worldwide. LDD can impact not only function, but can also become markedly disabling and cause severe chronic pain. Recent studies support the idea that analysis of sagittal balance is a crucial keypoint to optimize the management of lumbar degenerative diseases, especially when spinal instrumentation is intended. The first treatment of these pathologies is a medical treatment (medications, physical therapy and exercise). Surgical treatment is frequently necessary if the symptoms worsen and is generally a posterior spinal fusion with instrumentation (screws, hooks and rods) and bone graft. Basic principle of the surgery is to realign the spine along the rod. Despite documented techniques for surgical planning, it appears that a significant number of patients are ultimately under-corrected after surgery Realignment failure has not only been associated with poor functional outcome but also major complications, such as pseudoarthrosis and rod breakage, which often results in additional surgical procedures. From a pragmatic point of view, there are two main reasons for realignment failure: poor surgical planning and poor execution. One of the assumptions is that perioperative manual bending of the rod may not always allow the surgeon to restore the sagittal parameters as intended. A new concept of patient-specific rod (PSR) is now being proposed by a French manufacturer in order to enable an optimal correction and surgical stabilization of the spine. PSR are designed to fit with the patient's unique sagittal spine profile and with surgeons' surgical planning. However, no relevant clinical data is currently available to support the expected medical benefit of this new technology. The objective of the study is therefore to carry out a study hypothesizing that the use of PSR could improve the percentage of patients whose sagittal profile is optimally corrected after spinal surgery, as well as the patient's quality of life.
L5-S1 Disc Fate in Thoracolumbar Arthrodesis Stopping at L5
Spinal DeformitySpinal deformity in adults is one of the most frequently treated pathologies in spinal surgery. Their surgical treatment remains a challenge. In particular, the choice of the borderline vertebrae for thoracolumbar fusion correction remains controversial, including the choice between an instrumented last vertebra at L5 and an arthrodesis extending to the pelvis. Studies and meta-analyses show that an ilio-sacral socket provides better correction of pelvic parameters and avoids the development of distal junctional syndrome. On the other hand, there is more proximal junctional syndrome in patients fixed to the sacrum, and the sacral socket exposes patients to the risk of pseudarthrosis of the L5-S1 level and failure of the fixation hardware. Moreover, although this factor is not described in the studies, it would seem that an ilio-sacral socket is more stiffening. Overall, no study has shown a statistically significant difference in clinical scores between patients whose last instrumented vertebra is L5 and those with pelvic fixation. One of the theoretical risks of an extended fixation with a proximal thoracic grasp is to observe a premature disc degeneration of the L5-S1 disc since it would be subjected to more stress. This degeneration could be the cause of distal junctional syndrome and lumbo-radiculalgia due to inflammatory disc disease and disco-radicular impingement. However, to Investigator's knowledge, no clinical study has yet investigated the medium- and long-term fate of the L5-S1 disc in patients with extended fusion correction of a thoracic vertebra to L5. Investigator's team has sometimes favored a final instrumented vertebra at L5 when possible, i.e., when the L5-S1 disc was considered to be minimally or not degenerative and when its horizontality could be obtained after correction of the underlying curvature. Investigators therefore have a cohort of patients who have undergone this technique. The usual follow-up of these patients includes a consultation appointment every 2 to 5 years and a control MRI at a distance of more than 5 years: investigators thus have a control MRI and the clinical score of the patients. Investigator's objective is to determine whether there is degeneration of the L5-S1 disc, using MRI imaging data, which has never been published to investigator's knowledge.
Treatment of Venous Malformation
Venous MalformationVascular malformations are birth defects that happen when different stages of angiogenesis shut down. 44 - 64% of all vascular malformations are venous malformations (VMs). Sclerotherapy is the first treatment line for VMs. It acts by getting rid of the vascular endothelial cells in the lesion. One of the most common and well researched sclerosing agents for VMs is polidocanol, which is a popular counterpart for concentrated ethanol.
