There has been extensive discussion about the effect of delay to surgery on mortality in patients sustaining a fracture of the hip. Despite the low level of evidence provided by many studies, a consensus has been accepted that delay of > 48 hours is detrimental to survival. The aim of this prospective observational study was to determine if early surgery confers a survival benefit at 30 days. Between 1989 and 2013, data were prospectively collected on patients sustaining a fracture of the hip at Peterborough City Hospital. They were divided into groups according to the time interval between admission and surgery. These thresholds ranged from <  6 hours to between 49 and 72 hours. The outcome which was assessed was the 30-day mortality. Adjustment for confounders was performed using multivariate binary logistic regression analysis. In all, 6638 patients aged > 60 years were included. . Worsening American Society of Anaesthesiologists grade (p < 0.001), increased age (p <  0.001) and extracapsular fracture (p < 0.019) increased the risk of 30-day mortality. . Increasing mobility score (p = 0.014), mini mental test score (p < 0.001) and female gender (p = 0.014) improved survival. After adjusting for these confounders, surgery before 12 hours improved survival compared with surgery after 12 hours (p = 0.013). Beyond this the increasing delay to surgery did not significantly affect the 30-day mortality. Cite this article: Bone Joint J 2015;97-B:104–8

Aims. Several studies have reported that patients presenting during the evening or weekend have poorer quality healthcare. Our objective was to examine how timely surgery for patients with severe open tibial fracture varies by day and time of presentation and by type of hospital. This cohort study included patients with severe open tibial fractures from the Trauma Audit and Research Network (TARN). Methods. Provision of prompt surgery (debridement within 12 hours and soft-tissue coverage in 72 hours) was examined, using multivariate logistic regression to derive adjusted risk ratios (RRs). Time was categorized into three eight-hour intervals for each day of the week. The models were adjusted for treatment in a major trauma centre (MTC), sex, age, year of presentation, injury severity score, injury mechanism, and number of operations each patient received. Results. We studied 8,258 patients from 175 hospitals. Patients presenting during the day (08:00 to 15:59; risk ratio (RR) 1.11, 95% confidence interval (CI) 1.02 to 1.20) were more likely to receive debridement within 12 hours, and patients presenting at night (16:00 to 23:59; RR 0.56, 95% CI 0.51 to 0.62) were less likely to achieve the target; triage to a MTC had no effect. Day of presentation was associated with soft-tissue coverage within 72 hours; patients presenting on a Thursday or Friday being less likely to receive this surgery within 72 hours (Thursday RR 0.88, 95% CI 0.81 to 0.97; Friday RR 0.89, 95% CI 0.81 to 0.98), and the standard less likely to be achieved for those treated in ‘non-MTC’ hospitals (RR 0.76, 95% CI 0.70 to 0.82). Conclusion. Variations in care were observed for timely surgery for severe open tibial fractures with debridement surgery affected by time of presentation and soft-tissue coverage affected by day of presentation and type of hospital. The variation is unwarranted and highlights that there are opportunities to substantially improve the delivery and quality of care for patients with severe open tibial fracture.

Aims. The aim of this study was to describe the current pathways of care for patients with a fracture of the hip in five low- and middle-income countries (LMIC) in South Asia (Nepal and Sri Lanka) and Southeast Asia (Malaysia, Thailand, and the Philippines). Methods. The World Health Organization Service Availability and Readiness Assessment tool was used to collect data on the care of hip fractures in Malaysia, Thailand, the Philippines, Sri Lanka, and Nepal. Respondents were asked to provide details about the current pathway of care for patients with hip fracture, including pre-hospital transport, time to admission, time to surgery, and time to weightbearing, along with healthcare professionals involved at different stages of care, information on discharge, and patient follow-up. Results. Responses were received from 98 representative hospitals across the five countries. Most hospitals were publicly funded. There was consistency in clinical pathways of care within country, but considerable variation between countries. Patients mostly travel to hospital via ambulance (both publicly- and privately-funded) or private transport, with only half arriving at hospital within 12 hours of their injury. Access to surgery was variable and time to surgery ranged between one day and more than five days. The majority of hospitals mobilized patients on the first or second day after surgery, but there was notable variation in postoperative weightbearing protocols. Senior medical input was variable and specialist orthogeriatric expertise was unavailable in most hospitals. Conclusion. This study provides the first step in mapping care pathways for patients with hip fracture in LMIC in South Asia. The previous lack of data in these countries hampers efforts to identify quality standards (key performance indicators) that are relevant to each different healthcare system.

Aims. Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery. Methods. This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission. Results. Prolonged total length of stay was found when surgery was performed ≥ 24 hours (median 6 days (interquartile range (IQR) 4 to 9) vs 7 days (IQR 5 to 10); p = 0.001) after admission. No differences in postoperative length of hospital stay nor in 30-day mortality rates were found. In subgroup analysis for time frames of 12 hours each, pressure sores and urinary tract infections were diagnosed more frequently when time to surgery increased. Conclusion. Longer time to surgery due to non-medical reasons was associated with a higher incidence of postoperative pressure sores and urinary tract infections when time to surgery was more than 48 hours after admission. No association was found between time to surgery and 30-day mortality rates or postoperative length of hospital stay. Cite this article: Bone Joint J 2022;104-B(12):1369–1378

Aims. The aim of this study was to investigate mortality and risk of intraoperative medical complications depending on delay to hip fracture surgery by using data from the Norwegian Hip Fracture Register (NHFR) and the Norwegian Patient Registry (NPR). Patients and Methods. A total of 83 727 hip fractures were reported to the NHFR between 2008 and 2017. Pathological fractures, unspecified type of fractures or treatment, patients less than 50 years of age, unknown delay to surgery, and delays to surgery of greater than four days were excluded. We studied total delay (fracture to surgery, n = 38 754) and hospital delay (admission to surgery, n = 73 557). Cox regression analyses were performed to calculate relative risks (RRs) adjusted for sex, age, American Society of Anesthesiologists (ASA) classification, type of surgery, and type of fracture. Odds ratio (OR) was calculated for intraoperative medical complications. We compared delays of 12 hours or less, 13 to 24 hours, 25 to 36 hours, 37 to 48 hours, and more than 48 hours. Results. Mortality remained unchanged when total delay was less than 48 hours. Total delay exceeding 48 hours was associated with increased three-day mortality (RR 1.69, 95% confidence interval (CI) 1.23 to 2.34; p = 0.001) and one-year mortality (RR 1.06, 95% CI 1.04 to 1.22; p = 0.003). More intraoperative medical complications were reported when hospital delay exceeded 24 hours. Conclusion. Hospitals should operate on patients within 48 hours after fracture to reduce mortality and intraoperative complications. Cite this article: Bone Joint J 2019;101-B:1129–1137

Introduction. While there is a desperate need for effective treatments for acute spinal cord injury (SCI), the clinical validation of novel therapeutic interventions is severely hampered by the need to recruit relatively large numbers of patients into clinical trials for sufficient statistical power. While a centre might annually admit 100 acute SCI patients, only a fraction may satisfy the basic inclusion criteria for an acute clinical trial, which typically requires patients of a certain injury severity (eg ASIA A), within a specific time window (eg. 12 hours from injury), and without other major injuries or conditions that would cloud the baseline neurologic assessment. This study was conducted to define that “fraction” of SCI patients that would theoretically satisfy standard inclusion criteria of an acute clinical trial. Methods. Using a local database, we reviewed patients admitted to our Level 1 trauma center with a complete (ASIA A) or an incomplete (ASIA B, C and D) acute SCI involving bony spinal levels between C0 and sacrum. All patients admitted over the 4 year period from 2005 to 2009 were reviewed. Demographic information and data about the patients' SCI and other injuries were reviewed. We then determined how many of the total number of SCI patients would be eligible for enrolment into a hypothetical acute clinical trial that required a valid baseline assessment of neurologic impairment, and an enrolment window of either 12 hours, 24 hours, or 48 hours. Results. 408 acute traumatic SCI patients were admitted over the 4 year period. 253 of 408 (62%) patients presented within 12 hours of injury, 60 (15%) between 12–24 hours, and 28 (7%) between 24–48 hours. 42% of patients were ASIA A, 13% B, 18% C and 27% D. The number of patients who presented with injuries or other conditions that would exclude them from enrolment was relatively high: 4% had penetrating injuries, 12% had illicit drug use, and 20% had either alcohol intoxication or head injuries which precluded a valid baseline neurologic examination. Conclusions. Out of a total of 408 patients admitted over 4 years, the number who would have been optimistically eligible for an acute neuroprotective trial was disappointingly small. Given that acute clinical trials are increasingly interested in cervical ASIA A patients (in whom segmental motor recovery can be assessed), the number of such patients who would actually be eligible for an acute intervention was surprisingly low. Given that additional inclusion/exclusion criteria would also be applicable in a real clinical trial, the true number of “eligible” or “recruitable” patients is conservatively even lower. This study is the first to quantify this challenging aspects of conducting acute SCI clinical trials, and provides valuable information for those planning such initiative

Aims

This study estimated trends in incidence of open fractures and the adherence to clinical standards for open fracture care in England.

Between June 1999 and May 2003 we undertook direct primary closure of the skin wounds of 173 patients with Gustilo and Anderson grade-IIIA and grade-IIIB open fractures. These patients were selected from a consecutive group of 557 with type-III injuries presenting during this time. Strict criteria for inclusion in the study included debridement within 12 hours of injury, no sewage or organic contamination, no skin loss either primarily or secondarily during debridement, a Ganga Hospital open injury skin score of 1 or 2 with a total score of ten or less, the presence of bleeding skin margins, the ability to approximate wound edges without tension and the absence of peripheral vascular disease. In addition, patients with polytrauma were excluded. At a mean follow-up of 6.2 years (5 to 7), the outcome was excellent in 150 (86.7%), good in 11 (6.4%) and poor in 12 (6.9%). A total of 33 complications occurred in 23 patients including superficial infection in 11, deep infection in five and the requirement for a secondary skin flap in three. Six patients developed nonunion requiring further surgery, one of whom declined additional measures to treat an established infected nonunion. Immediate skin closure when performed selectively with the above indications proved to be a safe procedure

Objectives. The purpose of this study was to refine an accepted contaminated rat femur defect model to result in an infection rate of approximately 50%. This threshold will allow examination of treatments aimed at reducing infection in open fractures with less risk of type II error. Methods . Defects were created in the stablised femurs of anaethetised rats, contaminated with Staphylococcus aureus and then debrided and irrigated six hours later. After 14 days, the bone and implants were harvested for separate microbiological analysis. This basic model was developed in several studies by varying the quantity of bacterial inoculation, introducing various doses of systemic antibiotics with and without local antibiotics. Results . The bacterial inoculation associated with a 50% infection rate was established as 1 × 10. 2. colony forming units (CFU). With an initial bacterial inoculum of 1 × 10. 5. CFU, the dose of systemic antibiotics associated with 50% infection was 5 mg/Kg of cafazolin injected sub-cutaneously every 12 hours, starting at the time of the first debridment and continuing for 72 hours (seven doses). The systemic dose of cafazolin was lowered to 2 mg/Kg when antibiotic polymethyl methacrylate beads were used concurrently with the same amount of bacterial inoculation. Conclusion. This model of open fracture infection has been further refined with potential for local and systemic antibiotics. This is a versatile model and with the concepts presented herein, it can be modified to evaluate various emerging therapies and concepts for open fractures.

Introduction. Despite the routine use of irrigation, debridement and systemic antibiotics, there is a high incidence of infection in severe open fractures. The synergistic use of local and systemic antibiotics appreciably reduces infection rates although the time window within which this is effective is unknown. The aim was to determine if delaying treatment of wounds causes higher levels of infection. Methods. A defect was created in the femurs of 90 Sprague-Dawley rats and inoculated with 105CFUs Staphylococcus aureus. At 2, 6 and 24 hours following contamination, the defect was irrigated and debrided. The experimental groups had either vancomycin or tobramycin impregnated PMMA beads placed within the segmental defect. The controls received no further treatment. Two weeks after wound closure, the bacteria within the femur were quantified. Results. Delaying irrigation and debridement resulted in significantly more bacteria (p<0.01) within the control group (2 hr < 6 hr <24 hr). Both locally delivered tobramycin and vancomycin significantly reduced the bacteria (p<0.05) when administered at the earlier time points (2 and 6 hours). Locally-delivered antibiotics were ineffective when delivered at 24 hours. Conclusion. Delaying treatment of contaminated defects reduces its effectiveness to eradicate infection. This is presumably because of the biofilm formation by the bacteria. Biofilms begin to form within a couple of hours and are mature within 12 hours. Early treatment of the wound allows the surgeon to physically remove the bacteria or have antibiotics present before a mature biofilm protects the bacteria

Introduction and aim. Avascular necrosis (AVN) of femoral head remains a major post-operative complication of the surgical fixation of femoral neck fractures (#NOF). In order to reduce the incidence of AVN following this type of fracture, the National Institute for Clinical Excellence (NICE) has stated that fixation must occur within 6 hours. However, there is a paucity of information concerning whether time to fixation influences the development of AVN. The aim of the present study was to assess whether time to fixation affects the development of AVN in patients aged under 60 who had sustained a fracture (#)NOF. Methods. We looked retrospectively at 101 patients (61 female, 40 male aged under 60 (mean age 47 years) who were admitted to a multi-tertiary centre having sustained an intracapsular #NOF. The underlying co morbidity of the patient sample was varied, as was the mechanism of trauma, though in the majority of cases the cause was a simple fall. The time delay (TD) between the time of injury and the time of operation for each patient was determined. Results. 72 patients sustained an intracapsular displaced fracture and 29 an intracapsular undisplaced fracture. Of these, 33 patients were treated with a dynamic hip screw (DHS), 10 received a DHS plus a cannulated screw, and 54 were treated with cannulated screws only. We looked at time to fixation(TD) as follows: Group A-less than 6 hours (7 patients), Group B-6 to 12 hours (16 patients), Group C-12 to 18 hours (15 patients), Group D-18 to 24 hours (18 patients), Group E −24 to 48 hours (26 patients) and Group F- more than 48 hours(15 patients). Out of 97 patients, 15 (15.46%) developed AVN. Of these, 13 were patients who had sustained an intracapsular displaced fracture, two had sustained an undisplaced fracture. Of the intracapsular displaced fractures patients, the time to fixation varied from 3 hours to 26 hours post-trauma. Of note, twelve of these patients received a cannulated screw and only one was treated with a DHS. The two patients with an undisplaced intracapsular fracture underwent fixation at 13 and 24 hours respectively. The method of fixation was a cannulated screw. Conclusion. Current NICE guidelines state that intracapsular #NOF must be fixed within 6 hours in order to prevent AVN of femoral head. In our sample, 15.46% of patients developed AVN post-fixation. Crucially, 2 patients out of the 7 patients (28.57%) developed AVN despite undergoing fixation within 6 hours. Interestingly, we have observed that fracture fixation with a cannulated screw has a greater propensity to develop AVN despite time to fixation, since 15.46% of patients treated in this manner developed AVN. Taken together, method of fixation rather than time to fixation appears to be a key factor in the incidence of AVN in our patient group

We made a prospective study of 116 patients with tibial diaphyseal fractures who had continuous monitoring of anterior compartment pressure for 24 hours. Three patients had acute compartment syndrome (2.6%). In the first 12 hours of monitoring, 53 patients had absolute pressures over 30 mmHg and 30 had pressures over 40 mmHg, with four higher than 50 mmHg. Only one patient had a differential pressure (diastolic minus compartment pressure) of less than 30 mmHg; he had a fasciotomy. In the second 12-hour period 28 patients had absolute pressures over 30 mmHg and seven over 40 mmHg. Only two had differential pressures of less than 30 mmHg; they had fasciotomies. None of our 116 patients had any sequelae of the compartment syndrome at their latest review at least six months after injury. A threshold for decompression of 30 mmHg would have indicated that 50 patients (43%) would have required fasciotomy, and at a 40 mmHg threshold 27 (23%) would have been considered for an unnecessary fasciotomy. In our series, the use of a differential pressure of 30 mmHg as a threshold for fasciotomy led to no missed cases of acute compartment syndrome. We recommended that decompression should be performed if the differential pressure level drops to under 30 mmHg

Aims

To compare results of institutional preferences with regard to treatment of soft tissues in the setting of open tibial shaft fractures.

Aims

Open fractures of the tibia are a heterogeneous group of injuries that can present a number of challenges to the treating surgeon. Consequently, few surgeons can reliably advise patients and relatives about the expected outcomes. The aim of this study was to determine whether these outcomes are predictable by using the Ganga Hospital Score (GHS). This has been shown to be a useful method of scoring open injuries to inform wound management and decide between limb salvage and amputation.

Aims

The aim of this study was to evaluate near-infrared spectroscopy (NIRS) as a continuous, non-invasive monitor for acute compartment syndrome (ACS).

Aims

Little is known about the effect of haemorrhagic shock and resuscitation on fracture healing. This study used a rabbit model with a femoral osteotomy and fixation to examine this relationship.

Aims

We aimed to characterise the effect of expeditious hip fracture surgery in elderly patients within 24 hours of admission on short-term post-operative outcomes.

Fractures of the hip are common, often occurring in frail elderly patients, but also in younger fit healthy patients following trauma. They have a significant associated mortality and major social and financial implications to patients and health care providers. Many guidelines are available for the management of these patients, mostly recommending early surgery for the best outcomes. As a result, healthcare authorities now put pressure on surgical teams to ‘fast track’ patients with a fracture of the hip, often misquoting the available literature, which in itself can be confusing and even conflicting.

This paper has been written following an extensive review of the available literature. An attempt is made to clarify what is meant by early surgery (expeditious versus emergency), and we conclude with a personal view for the practical management of these patients of variable age, fitness and type of surgery performed within services that are often under considerable pressure of finance and available operating theatres and qualified staff.

Systemic antibiotics reduce infection in open fractures. Local delivery of antibiotics can provide higher doses to wounds without toxic systemic effects. This study investigated the effect on infection of combining systemic with local antibiotics via polymethylmethacrylate (PMMA) beads or gel delivery.

An established Staphylococcus aureus contaminated fracture model in rats was used. Wounds were debrided and irrigated six hours after contamination and animals assigned to one of three groups, all of which received systemic antibiotics. One group had local delivery via antibiotic gel, another PMMA beads and the control group received no local antibiotics. After two weeks, bacterial levels were quantified.

Combined local and systemic antibiotics were superior to systemic antibiotics alone at reducing the quantity of bacteria recoverable from each group (p = 0.002 for gel; p = 0.032 for beads). There was no difference in the bacterial counts between bead and gel delivery (p = 0.62).

These results suggest that local antibiotics augment the antimicrobial effect of systemic antibiotics. Although no significant difference was found between vehicles, gel delivery offers technical advantages with its biodegradable nature, ability to conform to wound shape and to deliver increased doses. Further study is required to see if the gel delivery system has a clinical role.

A total of 20 patients with a depressed fracture of the lateral tibial plateau (Schatzker II or III) who would undergo open reduction and internal fixation were randomised to have the metaphyseal void in the bone filled with either porous titanium granules or autograft bone. Radiographs were undertaken within one week, after six weeks, three months, six months, and after 12 months.

The primary outcome measure was recurrent depression of the joint surface: a secondary outcome was the duration of surgery.

The risk of recurrent depression of the joint surface was lower (p < 0.001) and the operating time less (p < 0.002) when titanium granules were used.

The indication is that it is therefore beneficial to use porous titanium granules than autograft bone to fill the void created by reducing a depressed fracture of the lateral tibial plateau. There is no donor site morbidity, the operating time is shorter and the risk of recurrent depression of the articular surface is less.
