Aims

There is increasing evidence to support the use of topical antibiotics to prevent surgical site infections. Although previous research suggests a minimal nephrotoxic risk with a single dose of vancomycin powder, fracture patients often require multiple procedures and receive additional doses of topical antibiotics. We aimed to determine if cumulative doses of intrawound vancomycin or tobramycin powder for infection prophylaxis increased the risk of drug-induced acute kidney injury (AKI) among fracture patients.

Post-natal vasculogenesis, the process by which vascular committed bone marrow stem cells or endothelial precursor cells migrate, differentiate and incorporate into the nacent endothelium and thereby contribute to physiological and pathological neurovascularisation, has stimulated much interest. Its contribution to neovascularisation of tumours, wound healing and revascularisation associated with ischaemia of skeletal and cardiac muscles is well established. We evaluated the responses of endothelial precursor cells in bone marrow to musculoskeletal trauma in mice. Bone marrow from six C57 Black 6 mice subjected to a standardised, closed fracture of the femur, was analysed for the combined expression of cell-surface markers stem cell antigen 1 (sca-1. +. ) and stem cell factor receptor, CD117 (c-kit. +. ) in order to identify the endothelial precursor cell population. Immunomagnetically-enriched sca-1. +. mononuclear cell (MNC. sca-1+. ) populations were then cultured and examined for functional vascular endothelial differentiation. Bone marrow MNC. sca-1+,c-kit+. counts increased almost twofold within 48 hours of the event, compared with baseline levels, before decreasing by 72 hours. Sca-1. +. mononuclear cell populations in culture from samples of bone marrow at 48 hours bound together Ulex Europus-1, and incorporated fluorescent 1,1′-dioctadecyl- 3,3,3,’3′-tetramethylindocarbocyanine perchlorate-labelled acetylated low-density lipoprotein intracellularily, both characteristics of mature endothelium. Our findings suggest that a systemic provascular response of bone marrow is initiated by musculoskeletal trauma. Its therapeutic manipulation may have implications for the potential enhancement of neovascularisation and the healing of fractures

Aims

Periprosthetic joint infections (PJIs) and fracture-related infections (FRIs) are associated with a significant risk of adverse events. However, there is a paucity of data on cardiac complications following revision surgery for PJI and FRI and how they impact overall mortality. Therefore, this study aimed to investigate the risk of perioperative myocardial injury (PMI) and mortality in this patient cohort.

Aims

Prompt and sufficient broad-spectrum empirical antibiotic treatment is key to preventing infection following open tibial fractures. Succeeding co-administration, we dynamically assessed the time for which vancomycin and meropenem concentrations were above relevant epidemiological cut-off (ECOFF) minimal inhibitory concentrations (T > MIC) in tibial compartments for the bacteria most frequently encountered in open fractures. Low and high MIC targets were applied: 1 and 4 µg/ml for vancomycin, and 0.125 and 2 µg/ml for meropenem.

Aims

The study objective was to prospectively assess clinical outcomes for a pilot cohort of tibial shaft fractures treated with a new tibial nailing system that produces controlled axial interfragmentary micromotion. The hypothesis was that axial micromotion enhances fracture healing compared to static interlocking.

Aims

Deep surgical site infection (SSI) is common after lower limb fracture. We compared the diagnosis of deep SSI using alternative methods of data collection and examined the agreement of clinical photography and in-person clinical assessment by the Centers for Disease Control and Prevention (CDC) criteria after lower limb fracture surgery.

Aims

Using tibial shaft fracture participants from a large, multicentre randomized controlled trial, we investigated if patient and surgical factors were associated with health-related quality of life (HRQoL) at one year post-surgery.

Aims

We aimed to evaluate the long-term impact of fracture-related infection (FRI) on patients’ physical health and psychological wellbeing. For this purpose, quality of life after successful surgical treatment of FRIs of long bones was assessed.

Sixty closed fractures of the tibia were treated by open reduction and internal fixation with plates and screws. Half the operations were performed with a thigh tourniquet and half without. In the tourniquet group, there were six cases with erythema and induration of the wound; in the other group there were no such complications. Despite negative bacterial cultures, superficial infection of the inflamed wounds was suspected. It is suggested that a tourniquet may predispose tissues to infection, and its use is not recommended during operations for internal fixation of the tibia

We have carried out a prospective study to determine whether the basic descriptive criteria and classifications of diaphyseal fractures of the tibia determine prognosis, as is widely believed. A number of systems which are readily available were used, with outcome being determined by standard measurements including fracture union, the need for secondary surgery and the incidence of infection. Many validated functional outcomes were also used. The Tscherne classification of closed fractures proved to be slightly more predictive of outcome than the others, but our findings indicate that such systems have little predictive value

1. The results of internal fixation are described in 470 tibial shaft fractures. 2. The immediate internal fixation of compound fractures was followed by so high an incidence of serious complications that the use of this method is not recommended. The immediate internal fixation of fresh closed fractures was also followed by many complications. 3. Delayed rigid internal fixation proved satisfactory for difficult fractures in which an acceptable reduction could not be obtained by closed means ; skeletal traction was of value in such fractures until the skin was soundly healed. 4. Delayed internal fixation reduced both the healing time and the complications

1. The conservative school of treatment of fractures of the tibia, which bases part of its criticism of internal fixation on the ultimate risk of amputation, does not often publish its own rates of amputation. 2. Statistics from a hospital that treats one-third of closed fractured tibiae and two-thirds of compound fractures by internal fixation are therefore put up as a basis for criticism. 3. Comparisons are made with the few available statistics in the literature of conservative treatment. 4. Almost all of the causes for secondary amputation are now curable and in recent years the number of limbs being saved is increasing

We studied the epidemiology of 401 fractures of the shaft of the humerus in 397 patients aged 16 years or older. The incidence was 14.5 per 100 000 per year with a gradually increasing age-specific incidence from the fifth decade, reaching almost 60 per 100 000 per year in the ninth decade. Most were closed fractures in elderly patients which had been sustained as the result of a simple fall. The age distribution in women was characterised by a peak in the eighth decade while that in men was more even. Simple fractures were by far the most common and most were located in the middle or proximal shaft. The incidence of palsy of the radial nerve was 8% and fractures in the middle and distal shaft were most likely to be responsible. Only 2% of the fractures were open and 8% were pathological. These figures are representative of a population with a low incidence of high-energy and penetrating trauma, which probably reflects the situation in most European countries

We have reviewed 402 traumatic fractures of the femoral shaft, 320 of which had been treated by operation and had a long follow-up. Of these, 228 closed fractures and 37 open fractures had been stabilised by plating. There was no significant difference in healing between those stabilised early and those having delayed internal fixation. Re-fracture after removal of the implant occurred more often after early operation. All 55 fractures treated by intramedullary nailing healed and there were no re-fractures after nail removal. We found no correlation between delay before operation and the incidence of postoperative infection

Intracompartmental pressures of 66 patients with 67 tibial fractures treated by intramedullary nailing were monitored. There was no difference in the pressures recorded between the different Tscherne fracture types, between open and closed fractures, between low energy and high energy injuries or between fractures dealt with early and those not treated until more than 24 hours after injury. The overall incidence of acute compartment syndrome was 1.5%. No patient developed any sequelae of compartment syndrome. We conclude that intramedullary nailing does not increase the incidence of acute compartment syndrome in tibial fractures and that delay does not reduce the risk of raised compartment pressures

One hundred consecutive closed fractures of the adult tibial shaft treated by closed methods were surveyed prospectively in order to observe their natural history. The fractures were analysed with regards to speed of healing and the influence of age, sex, causal force, radiological morphology and concurrent fibular fracture. At 20 weeks 19 fractures had not yet united, but 15 of these had united by 30 weeks with conservative treatment alone. The remaining four cases were operated upon because no further progress in healing was anticipated. These findings suggest that, with regard to healing, open reduction and internal fixation is rarely justified in closed adult tibial shaft fractures
