It is a systemic disease, characterized by vaso-occlusive phenomena, especially in the bone capillary network. Orthopedic complications are thus the most common, with a strong impact on quality of life. In children, these complications mainly comprise bone infarction, epiphyseal aseptic osteonecrosis, and bone and joint infection: acute or chronic osteomyelitis, osteoarthritis and septic arthritis. Aseptic osteonecrosis mainly involves the proximal extremities of the femur and humerus. It may be completely asymptomatic in childhood, but almost systematically deteriorates during the 3rd decade without early management, while in childhood there are opportunities for revascularization and remodeling. Prognosis is more severe in sickle-cell-related than community-based childhood bone and joint infection, as treatment is often delayed by diagnostic difficulties due to the absence of specific clinical and paraclinical signs differentiating it from an acute vaso-occlusive crisis. The most common pathogens are minor Salmonella and Staphylococcus aureus. Due to high rates of iterative surgery and sequelae, systematic radio-clinical monitoring is required. Any surgery in children with sickle-cell disease requires special precautions, based primarily on preventive measures to avoid dehydration, hypoxia, hypothermia, acute anemia and pain that can trigger a life-threatening vaso-occlusive crisis. All orthopedic complications should be managed in a specialized reference center with experienced multidisciplinary medical-surgical teams.

The first part of the tests consisted of taking these measurements with the repaired subscapularis tendon.

It is a relatively recent technique, and indications are evolving with progress in pre- and intra-operative imaging. Morbidity is lower than with open surgery. PPS is classically performed under fluoroscopy; computer-assisted surgery is of great interest, enabling analysis of safe bone corridors. Planning is based on image processing tools included in CT DICOM viewer packages. The aim of the present study was to review PPS. What are the indications for PPS? All pelvic ring fractures are in principle concerned if the reduction allows passage of a K-wire and then a screw. A distinction is to be made between, on the one hand, young patients, able to support a variable period of non-weight-bearing, in whom PPS stabilizes an unstable fracture, relieves pain on motion and prevents non-union, and, on the other hand, older patients for whom PPS enables optimally early resumption of weight-bearing. How to plan posterior PPS? The principal procedures are iliosacral screwing (ISS), trans-sacral screwing (TSS) and supra-acetabular screwing (SAS). How to plan anterior PPS? The principal procedures are anterior column/superior pubic ramus (AC/SPR) screwing, iliac wing screwing (IWS) and gluteal pillar screwing. How to plan percutaneous acetabular screwing (PAS)? The principal procedures are transverse acetabular screwing (TAS) and retrograde posterior column screwing (RPCS) or \"butt screw\". Fixation is demanding. PPS requires rigorous preoperative planning using CT DICOM viewer software. The principle consists in multiplane reconstruction of bone corridors, to assess the feasibility of PPS and analyze implant diameters, tracing lines to measure implant trajectory and length, and 3D reconstruction using the measurements, to assess entry and exit points and forecast intraoperative fluoroscopic views. What results, what complications, what innovations? Results are comparable to those of open surgery, with significantly less morbidity. The main complications are implant malpositioning and fixation failure, with secondary displacement of the fracture and/or implants. 3D printing, navigation and, recently, robotic surgery constitute the future of PPS. How PPS can go wrong? Difficulties or errors in planning, errors in patient positioning or errors in reading fluoroscopy are the main pitfalls. When available, intraoperative 3D imaging, associated to navigation or not, improves safety.</p>","PeriodicalId":54664,"journal":{"name":"Orthopaedics & Traumatology-Surgery & Research","volume":" ","pages":"104392"},"PeriodicalIF":2.2,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(1) In what circumstances is amputation necessary in traumatology? (2) Are scores and results analyses contributive to decision-making for emergency amputation? Amputation can be primary, when directly caused by the trauma, salvage if limb conservation would be life-threatening, a necessity if functional prognosis is poor, or else necessitated by a mass-casualty context. Score systems and results analysis can help identify patients who would benefit from amputation or salvage, but applications are controversial, and the surgeon's expertise is a determining factor for treatment option in emergency settings. (3) What are the technical principles of amputation in traumatology? These principles must take account of the limitations imposed by emergency settings, in which the stump cannot always be optimized. In the acute phase, non-closure is the rule, and delayed stump shaping is preferable, to limit complications. (4) What quality of life can the amputee expect? Quality of life is a major issue in traumatic amputation. Prosthetics can restore walking capacity and promote social, occupational and familial autonomy. (5) How can complications be prevented and treated after traumatic amputation? Frequent complications include infection, cover defect, heterotopic ossification and chronic pain. These often require adaptation of the prosthesis or surgery by a specialized team. (6) Apart from surgery, what considerations guide management? Other aspects have to be integrated in the care pathway: regulatory considerations, shared decision-making, multidisciplinary teamwork, and psychological and social factors.</p>","PeriodicalId":54664,"journal":{"name":"Orthopaedics & Traumatology-Surgery & Research","volume":" ","pages":"104389"},"PeriodicalIF":2.2,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144979178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
