Musculoskeletal trauma imaging in the era of novel molecular methods and artificial intelligence.
Over the past decade rapid advancements in molecular imaging (MI) and artificial intelligence (AI) have revolutionized traditional musculoskeletal radiology. Molecular imaging refers to the ability of various methods to in vivo characterize and quantify biological processes, at a molecular level. The extracted information provides the tools to understand the pathophysiology of diseases and thus to early detect, to accurately evaluate the extend and to apply and evaluate targeted treatments. ⋯ Notably, the development of deep learning algorithms has offered novel methods that enable intelligent processing of large imaging datasets in an attempt to automate decision-making in a wide variety of settings related to musculoskeletal trauma. Current applications of AI include the diagnosis of bone and soft tissue injuries, monitoring of the healing process and prediction of injuries in the professional sports setting. This review presents the current applications of novel MI techniques and methods and the emerging role of AI regarding the diagnosis and evaluation of musculoskeletal trauma.

Extensive soft tissue loss or injury of the hand and upper extremity is a challenging reconstructive problem traditionally treated with abdominal-based pedicled flaps. Options for coverage included the groin flap based on the superficial circumflex iliac artery, the Scarpa's fascia flap based on the superficial inferior epigastric artery, and the paraumbilical perforator flap from the deep inferior epigastric artery perforators. Despite the ability to provide consistent and pliable soft tissue coverage with ease of elevation, these flaps have several disadvantages including restriction of mobility, requirement for multiple procedures, bulkiness and patient discomfort. ⋯ However several indications still remain. These include: patient and facility factors which deter microsurgery, the absence of recipient vessels after injury, prior surgical use of recipient vessels, the need to preserve major vessels for future reconstruction, and large multi-surface wounds requiring coverage. In this review we detail these indications and provide case examples for each.

Review Case Reports
Phlegmasia cerulea dolens following internal hemipelvectomy: Case report and literature review.
Phlegmasia cerulea dolens (PCD) results from near complete venous thrombosis and occlusion in an extremity resulting in pain, cyanosis, and edema and potentially death. While PCD can result from a variety of mechanisms including trauma, iatrogenic instrumentation, the majority of cases occur in the setting of malignancy. ⋯ Here, we present a unique case of phlegmasia cerulea dolens occurring following an internal hemipelvectomy requiring emergent surgical intervention to salvage life and limb. A review of the literature regarding diagnosis and treatment is also presented.

Approximately 75% of fractures are simple, stable injuries which are often unnecessarily immobilised with subsequent repeated radiographs at numerous fracture clinic visits. In 2014, the Glasgow Fracture Pathway offered an alternative virtual fracture clinic (VFC) pathway with the potential to reduce traditional fracture clinic visits, waiting times and overall costs. Many units have implemented this style of pathway in the non-operative management of simple, undisplaced fractures. This study aims to systematically review the clinical outcomes, patient reported outcomes and cost analyses for VFCs. ⋯ IV; Systematic Review of all Levels of Evidence.

One third of paediatric femoral fractures occur between the ages of 5 and 12. The American Academy of Orthopaedic Surgeons (AAOS) provide evidence-based guidance for treating such fractures that occur in children under 5 and over 12 but not for this age cohort. We aimed to synthesise the available evidence comparing flexible nailing versus plating techniques for diaphyseal femoral fractures in children between the ages of 5 and 12. ⋯ Data on this topic for this age group is limited despite accounting for one third of paediatric femoral fractures. This review identified a significantly increased relative risk of all complications, and in particular with respect to malunion and prominent metalwork when fractures in this cohort are treated with flexible nails compared to plates. A multi-centre randomised trial to determine if either treatment is superior would be justified.
