The aim of this study was to describe the epidemiology of closed
isolated fractures of the femoral shaft in children, and to compare
the treatment and length of stay (LOS) between major trauma centres
(MTCs) and trauma units (TUs) in England. National data were obtained from the Trauma and Audit Research
Network for all isolated, closed fractures of the femoral shaft
in children from birth to 15 years of age, between 2012 and 2015.
Age, gender, the season in which the fracture occurred, non-accidental
injury, the mechanism of injury, hospital trauma status, LOS and
type of treatment were recorded.Aims
Patients and Methods
Periprosthetic proximal femoral fractures (PFFs) are a major complication after total hip arthroplasty (THA). Health status after PFF is not specifically investigated. The aim of this study is to evaluate the health status pattern over two years after sustaining a PFF. A cohort of patients with PFF after THA was derived from the Brabant Injury Outcomes Surveillance (BIOS) study. The BIOS study, a prospective, observational, multicentre follow-up cohort study, was conducted to obtain data by questionnaires pre-injury and at one week, and one, three, six, 12, and 24 months after trauma. Primary outcome measures were the EuroQol five-dimension three-level questionnaire (EQ-5D-3L), the Health Utility Index 2 (HUI2), and the Health Utility Index 3 (HUI3). Secondary outcome measures were general measurements such as duration of hospital stay and mortality.Aims
Methods
Earlier studies dealing with trends in the management of osteonecrosis of the femoral head (ONFH) identified an increasing rate of total hip arthroplasties (THAs) and a decreasing rate of joint-preserving procedures between 1992 and 2008. In an effort to assess new trends in the management of this condition, this study evaluated the annual trends of joint-preserving versus arthroplasties for patients aged < or > 50 years old, and the incidence of specific operative management techniques. A total of 219,371 patients with ONFH were identified from a nationwide database between 1 January 2009 and 31 December 2015. The mean age was 54 years (18 to 90) and 105,298 (48%) were female. The diagnosis was made using International Classification of Disease, Ninth revision, Clinical Modification (ICD-9-CM) and Tenth Revision, Clinical Modification (ICD-10-CM) procedure codes. The percentage of patients managed using each procedure during each year was calculated and compared between years. The trends in the use of the types of procedure were also evaluated.Aims
Methods
Patients with infected arthroplasties are normally
treated with a two-stage exchange procedure using polymethylmethacrylate
bone cement spacers impregnated with antibiotics. However, spacers
may act as a foreign body to which micro-organisms may adhere and
grow. In this study it was hypothesised that subclinical infection may
be diagnosed with sonication of the surface biofilm of the spacer.
The aims were to assess the presence of subclinical infection through
sonication of the spacer at the time of a second-stage procedure,
and to determine the relationship between subclinical infection
and the clinical outcome. Of 55 patients studied, 11 (20%) were
diagnosed with subclinical infection. At a mean follow-up of 12
months (interquartile range 6 to 18), clinical failure was found in
18 (32.7%) patients. Of the patients previously diagnosed with subclinical
infection, 63% (7 of 11) had failed compared with 25% (11 of 44)
of those without subclinical infection (odds ratio 5.25, 95% confidence
interval 1.29 to 21.4, p = 0.021). Sonication of the biofilm of
the surface of the spacer is useful in order to exclude subclinical infection
and therefore contributes to improving the outcome after two-stage
procedures.
The incidence and long-term outcome of undisplaced fatigue fractures of the femoral neck treated conservatively were examined in Finnish military conscripts between 1970 and 1990. From 106 cases identified, 66 patients with 70 fractures were followed for a mean of 18.3 years (11 to 32). The original medical records and radiographs were studied and physical and radiological follow-up data analysed for evidence of risk factors for this injury. The development of avascular necrosis and osteoarthritis was determined from the follow-up radiographs and MR scans. The impact of new military instructions on the management of hip-related pain was assessed following their introduction in 1986. The preventive regimen (1986) improved awareness and increased the detected incidence from 13.2 per 100 000 service-years (1970 to 1986) to 53.2 per 100 000 (1987 to 1990). No patient developed displacement of the fracture or avascular necrosis of the femoral head, or suffered from adverse complications. No differences were found in MRI-measured hip joint spaces at final follow-up. The mean Harris Hip Score was 97 (70 to 100) and the Visual Analogue Scale 5.85 mm (0 to 44). Non-operative treatment, including avoidance of or reduced weight-bearing, gave favourable short- and long-term outcomes. Undisplaced fatigue fractures of the femoral neck neither predispose to avascular necrosis nor the subsequent development of osteoarthritis of the hip.
