Aims

The modern prevalence of primary tumours causing metastatic bone disease is ill-defined in the oncological literature. Therefore, the purpose of this study is to identify the prevalence of primary tumours in the setting of metastatic bone disease, as well as reported rates of pathological fracture, postoperative complications, 90-day mortality, and 360-day mortality for each primary tumour subtype.

Aims

The use of high tibial osteotomy (HTO) to delay total knee arthroplasty (TKA) in young patients with osteoarthritis (OA) and constitutional deformity remains debated. The aim of this study was to compare the long-term outcomes of TKA after HTO compared to TKA without HTO, using the time from the index OA surgery as reference (HTO for the study group, TKA for the control group).

Aims

The aim of this study to compare 30-day survival and recovery of mobility between patients mobilized early (on the day of, or day after surgery for a hip fracture) and patients mobilized late (two days or more after surgery), and to determine whether the presence of dementia influences the association between the timing of mobilization, 30-day survival, and recovery.

Ankle fractures are among the most common type of fractures of our musculoskeletal system, and their rate has been constantly increasing over the past decades, not only in the young active patients but also in the elderly ones. The stability of the ankle joint is assured by the configuration of the fibula, tibia and talus, as well as by its complex ligamentous system. The optimal treatment of these fractures follows the basic rules of all joint fractures: it is achieved by restoring the ankle mortise and its stability, in order to prevent pain and the development of secondary arthritis. Stable ankle fractures (e.g., isolated fractures of lateral maleolus) can be satisfactorily treated by closed methods, whereas unstable fractures (e.g., bimaleolar, bilameolar equivalents, trimaleolar) must be treated by open reduction and internal fixation. However, one of the aspects that influence the final outcome of these fractures is the coexistence of soft tissue injuries and osteochondral fractures (particularly of the talus), especially if not detected in the X-ray or intra-operative, which will inevitably degenerate in a posttraumatic arthritis. The authors present in this paper a retrospective study of all patients with ankle fractures treated operatively in a period of ten years (January 1993 and December 2003). It where reviewed 376 clinical processes, with a male patient predominance (57%). The fractures where classified according to the Dannis-Weber Classification, and the following items where evaluated: epidemiology, co-morbidities, surgery timing, hospitalization time, surgical options, surgical follow-up and complications. The final evaluation of the patients included clinical, functional and radiological aspects. The authors concluded that in spite of the surgical treatment being well established and indicated in the unstable fractures, its results are frequently influenced by the epidemiologic cofactors, co-morbidities, injury mechanism, coexistence of soft tissue injuries or osteochondral fractures that many times are not detected

Introduction High precision of axis alignement in Total Knee Arthroplasty by usage of navigation tools is a known fact. However, a common disadvantage of navigation tools is the additional time needed for calibration. Especially in time/cost-sensitive hospital environments this can lead to a neglection of navigation tools usage. In this study we address work-economics during navigation assisted total knee arthroplasty. Specifically, we introduce the concept of a well-trained navigator assistant who performs navigation related work steps during surgery while the primary surgeon concentrates on the remaining work-steps. In a prospective study of primary TKA we compared environmental parameters of surgeries performed with and without the Navigator Concept. Materials and Methods 60 Total Knee Arthroplasties were performed using an active navigation system (Stryker Navigation System) (40) or a conventional internal/external alignement jig for implantation of the Interax Knee endoprostheses. Half of the navigated knee arthroplasties were performed using a conventional set-up with a primary surgeon and two assistants serving the navigation system and performing the relevant surgical steps. The other half was done by surgeon teams of a primary surgeon, a navigator assistant and a second assistant. The surgical steps were broken down to a complex work-sharing system. The teams were intensively trained in their work-share by simulating an artificial TKA in a specially designed TKA-Navigation lab. During surgery, the timing of individual steps was recorded. Pre- and postoperative x-rays of the limbs were taken and digitized to an computerized axis-measurement system. Data of both groups were compared using ANOVA and Tuckey post-hoc tests. Results Results showed a significant difference in surgery time between the three groups (p=0,01) with equivalent surgery times of the conventional and navigator concept group, while the remaining navigated group showed longer surgery times. Axis alignments were statistically not influenced, however demonstrated a tendency to higher precision in the navigator concept group. Discussion This study is the first to address work-economics in navigated TKA. With the introduction of a specifically trained navigator assistant, a precise work-sharing plan and an intensive training lab, high precision in TKA can be achieved by navigation usage even in a highly cost-sensitive environment. The basis for success, however, is support and investment in training of team surgeons. This concept may provide the basis for other musculoskeletal surgeries demanding both high-tech for precision and time-effectiveness for cost reduction

The February 2015 Trauma Roundup³⁶⁰ looks at: Evaluating the syndesmosis in ankle fractures; Calcaneal fracture management an ongoing problem; Angular stable locking in low tibial fractures did not improve results; Open fractures: do the seconds really count?; Long-term outcomes of tibial fractures; Targeted performance improvements in pelvic fractures

Objectives

To determine the morbidity and mortality outcomes of patients presenting with a fractured neck of femur in an Australian context. Peri-operative variables related to unfavourable outcomes were identified to allow planning of intervention strategies for improving peri-operative care.
