“…Although sparse, the current literature supports intraoperative use in more difficult, impacted, and displaced acetabular fractures. Intraoperative imaging demonstrated improved articular reduction accuracy by 2 mm, while OR time was not significantly increased [8]. Intraoperative use can be considered in the more complex, displaced acetabular fractures especially when intra-articular bony fragments were identified pre-operatively and the surgeon is unsure of complete removal.…”

Acetabular fractures are injuries that require significant force transmission, especially when associated with a femoral head dislocation. The mechanism of injury is typically in the setting of a high-speed motor vehicle collision. In a similar manner, this is an injury that is highly demanding for the orthopaedic trauma surgeon to treat as well. We present a patient who sustained an initial posterior wall acetabular fracture with an associated posterior dislocation. This was treated surgically with open reduction, internal fixation without complication. The patient subsequently sustained a second posterior wall acetabular fracture with dislocation fifteen years later through the plated and healed previous fracture. Both injuries were sustained in high-speed motor vehicle collisions, so it is difficult to presume the patient was predisposed for the repeat injury. At any rate, the repeat injury makes the surgical management significantly more challenging. In complicated acetabular fractures like these, a post or intra-operative CT scan can be of utility to determine quality of reduction as well as assessing for retained bony fragments. Our patient underwent a post-operative CT scan with the finding of intra-articular bony fragments that subsequently required arthroscopic removal. Given the rare nature of this complicated injury occurring twice in a patient, it is difficult to make evidence-based comments on long-term prognosis and functional outcomes. This unique case and the applied treatment will serve as a guide for future similar cases.

“…90 Excellent agreement with MDCT for distal extremity fractures has been reported, proving particularly advantageous when combined with better tolerance and lower effective radiation dose provided by CBCT. 91 In addition to imaging trauma and fracture in extremities, CBCT has been used intraoperatively to aid vertebral body stentoplasty, kyphoplasty, and vertebroplasty 92 and repair isolated displaced talar fractures, 93 displaced acetabular fractures, 94 and tibial plafond fractures. 95 Recent advancements show feasibility of FOV expansion of CBCT scans, enabling visualization of long anatomical sites intraoperatively.…”

Although musculoskeletal magnetic resonance imaging (MRI) plays a dominant role in characterizing abnormalities, novel computed tomography (CT) techniques have found an emerging niche in several scenarios such as trauma, gout, and the characterization of pathologic biomechanical states during motion and weight-bearing. Recent developments and advancements in the field of musculoskeletal CT include 4-dimensional, cone-beam (CB), and dual-energy (DE) CT. Four-dimensional CT has the potential to quantify biomechanical derangements of peripheral joints in different joint positions to diagnose and characterize patellofemoral instability, scapholunate ligamentous injuries, and syndesmotic injuries. Cone-beam CT provides an opportunity to image peripheral joints during weight-bearing, augmenting the diagnosis and characterization of disease processes. Emerging CBCT technologies improved spatial resolution for osseous microstructures in the quantitative analysis of osteoarthritis-related subchondral bone changes, trauma, and fracture healing. Dual-energy CT–based material decomposition visualizes and quantifies monosodium urate crystals in gout, bone marrow edema in traumatic and nontraumatic fractures, and neoplastic disease. Recently, DE techniques have been applied to CBCT, contributing to increased image quality in contrast-enhanced arthrography, bone densitometry, and bone marrow imaging. This review describes 4-dimensional CT, CBCT, and DECT advances, current logistical limitations, and prospects for each technique.

“…Their high image quality and large visualization volume enables immediate control of reduction and implant position, which can reduce the incidence of revision surgery. 92 Furthermore, the reduction of the injured side can be compared to the uninjured side in the operating room (e.g. pelvic ring fractures).…”

Finding NEEMO: towards organizing smart digital solutions in orthopaedic trauma surgery

There are many digital solutions which assist the orthopaedic trauma surgeon. This already broad field is rapidly expanding, making a complete overview of the existing solutions difficult. The AO Foundation has established a task force to address the need for an overview of digital solutions in the field of orthopaedic trauma surgery. Areas of new technology which will help the surgeon gain a greater understanding of these possible solutions are reviewed. We propose a categorization of the current needs in orthopaedic trauma surgery matched with available or potential digital solutions, and provide a narrative overview of this broad topic, including the needs, solutions and basic rules to ensure adequate use in orthopaedic trauma surgery. We seek to make this field more accessible, allowing for technological solutions to be clearly matched to trauma surgeons’ needs. Cite this article: EFORT Open Rev 2020;5:408-420.
