Delayed postoperative inoculation of orthopaedic implants with persistent wound drainage or bacterial seeding of a haematoma can result in periprosthetic joint infection (PJI). The aim of this in vivo study was to compare the efficacy of vancomycin powder with vancomycin-eluting calcium sulphate beads in preventing PJI due to delayed inoculation. A mouse model of PJI of the knee was used. Mice were randomized into groups with intervention at the time of surgery (postoperative day (POD) 0): a sterile control (SC; n = 6); infected control (IC; n = 15); systemic vancomycin (SV; n = 9); vancomycin powder (VP; n = 21); and vancomycin bead (VB; n = 19) groups. Delayed inoculation was introduced during an arthrotomy on POD 7 with 1 × 105 colony-forming units (CFUs) of a bioluminescent strain of Aims
Methods
The aim of this study was to investigate the relationship between the Orthopaedic Trauma Society (OTS) classification of open fractures and economic costs. Resource use was measured during the six months that followed open fractures of the lower limb in 748 adults recruited as part of two large clinical trials within the UK Major Trauma Research Network. Resource inputs were valued using unit costs drawn from primary and secondary sources. Economic costs (GBP sterling, 2017 to 2018 prices), estimated from both a NHS and Personal Social Services (PSS) perspective, were related to the degree of complexity of the open fracture based on the OTS classification.Aims
Methods
The aim of this study was to assess whether it is possible to predict the mortality, and the extent and time of neurological recovery from the time of the onset of symptoms and MRI grade, in patients with the cerebral fat embolism syndrome (CFES). This has not previously been investigated. The study included 34 patients who were diagnosed with CFES following trauma between 2012 and 2018. The clinical diagnosis was confirmed and the severity graded by MRI. We investigated the rate of mortality, the time and extent of neurological recovery, the time between the injury and the onset of symptoms, the clinical severity of the condition, and the MRI grade. All patients were male with a mean age of 29.7 years (18 to 70). The mean follow-up was 4.15 years (2 to 8), with neurological recovery being assessed by the Glasgow Outcome Scale and the Mini-Mental State Examination.Aims
Methods
Use of the direct anterior approach (DAA) for total hip arthroplasty (THA) has increased in recent years due to proposed benefits, including a lower risk of dislocation and improved early functional recovery. This study investigates the dislocation rate in a non-selective, consecutive cohort undergoing THA via the DAA without any exclusion or bias in patient selection based on habitus, deformity, age, sex, or fixation method. We retrospectively reviewed all patients undergoing THA via the DAA between 2011 and 2017 at our institution. Primary outcome was dislocation at minimum two-year follow-up. Patients were stratified by demographic details and risk factors for dislocation, and an in-depth analysis of dislocations was performed.Aims
Methods
Despite long-standing dogma, a clear relationship between the timing of surgical irrigation and debridement (I&D) and the development of subsequent deep infection has not been established in the literature. Traditionally, I&D of an open fracture has been recommended within six hours of injury based on animal studies from the 1970s, however the clinical basis for this remains unclear. Using data from a multicentre randomized controlled trial of 2,447 open fracture patients, the primary objective of this secondary analysis is to determine if a relationship exists between timing of wound I&D (within six hours of injury vs beyond six hours) and subsequent reoperation rate for infection or healing complications within one year for patients with open limb fractures requiring surgical treatment. To adjust for the influence of patient and injury characteristics on the timing of I&D, a propensity score was developed from the dataset. Propensity-adjusted regression allowed for a matched cohort analysis within the study population to determine if early irrigation put patients independently at risk for reoperation, while controlling for confounding factors. Results were reported as odds ratios (ORs), 95% confidence intervals (CIs), and p-values. All analyses were conducted using STATA 14.Aims
Methods
Aims.
To clarify the effectiveness of the induced membrane technique (IMT) using beta-tricalcium phosphate (β-TCP) for reconstruction of segmental bone defects by evaluating clinical and radiological outcomes, and the effect of defect size and operated site on surgical outcomes. A review of the medical records was conducted of consecutive 35 lower limbs (30 males and five females; median age 46 years (interquartile range (IQR) 40 to 61)) treated with IMT using β-TCP between 2014 and 2018. Lower Extremity Functional Score (LEFS) was examined preoperatively and at final follow-up to clarify patient-centered outcomes. Bone healing was assessed radiologically, and time from the second stage to bone healing was also evaluated. Patients were divided into ≥ 50 mm and < 50 mm defect groups and into femoral reconstruction, tibial reconstruction, and ankle arthrodesis groups.Aims

The aims of this study were to quantify health state utility
values (HSUVs) after a tibial fracture, investigate the effect of
complications, to determine the trajectory in HSUVs that result
in these differences and to quantify the quality-adjusted life years
(QALYs) experienced by patients. This is an analysis of 2138 tibial fractures enrolled in the
Fluid Lavage of Open Wounds (FLOW) and Study to Prospectively Evaluate
Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT)

Patients and Methods
The aim of this study was to describe the technique of distraction
osteogenesis followed by arthrodesis using internal fixation to
manage complex conditions of the ankle, and to present the results
of this technique. Between 2008 and 2014, distraction osteogenesis followed by arthrodesis
using internal fixation was performed in 12 patients with complex
conditions of the ankle due to trauma or infection. There were eight
men and four women: their mean age was 35 years (23 to 51) at the
time of surgery. Bone healing and functional recovery were evaluated
according to the criteria described by Paley. Function was assessed
using the ankle-hindfoot scale of the American Orthopedic Foot and
Ankle Society (AOFAS).Aims
Patients and Methods
To evaluate interobserver reliability of the Orthopaedic Trauma
Association’s open fracture classification system (OTA-OFC). Patients of any age with a first presentation of an open long
bone fracture were included. Standard radiographs, wound photographs,
and a short clinical description were given to eight orthopaedic
surgeons, who independently evaluated the injury using both the
Gustilo and Anderson (GA) and OTA-OFC classifications. The responses
were compared for variability using Cohen’s kappa.Aims

This study describes the use of the Masquelet technique to treat
segmental tibial bone loss in 12 patients. This retrospective case series reviewed 12 patients treated between
2010 and 2015 to determine their clinical outcome. Patients were
mostly male with a mean age of 36 years (16 to 62). The outcomes
recorded included union, infection and amputation. The mean follow-up
was 675 days (403 to 952). Aims
Patients and Methods
Aims. Following the introduction of national standards in 2009, most
major paediatric trauma is now triaged to specialist units offering
combined orthopaedic and plastic surgical expertise. We investigated
the management of open tibia fractures at a paediatric trauma centre,
primarily reporting the risk of infection and rate of union. Patients and Methods. A retrospective review was performed on 61 children who between
2007 and 2015 presented with an open tibia fracture. Their mean
age was nine years (2 to 16) and the median follow-up was ten months
(interquartile range 5 to 18). Management involved IV antibiotics,
early debridement and combined treatment of the skeletal and soft-tissue injuries
in line with standards proposed by the British Orthopaedic Association. Results. There were 36 diaphyseal fractures and 25 distal tibial fractures.
Of the distal fractures, eight involved the physis. Motor vehicle
collisions accounted for two thirds of the injuries and 38 patients
(62%) arrived outside of normal working hours. The initial method
of stabilisation comprised: casting in nine cases (15%); elastic
nailing in 19 (31%); Kirschner (K)-wiring in 13 (21%); intramedullary
nailing in one (2%); open reduction and plate fixation in four (7%); and
external fixation in 15 (25%). Wound management comprised: primary
wound closure in 24 (39%), delayed primary closure in 11 (18%),
split skin graft (SSG) in eight (13%), local flap with SSG in 17
(28%) and a free flap in one. A total of 43 fractures (70%) were
Gustilo-Anderson grade III. There were four superficial (6.6%) and
three (4.9%) deep infections. Two deep infections occurred following
open reduction and plate fixation and the third after
K-wire fixation of a distal fracture. No patient who underwent primary
wound closure developed an infection. All the fractures united,
although nine patients required revision of a mono-lateral to circular
frame for delayed union (two) or for altered alignment or length
(seven). The mean time to union was two weeks longer in diaphyseal fractures
than in distal fractures (13 weeks versus 10.8
weeks, p = 0.016). Children aged >
12 years had
a significantly longer time to union than those aged <
12 years
(16.3 weeks versus 11.4 weeks, p = 0.045).
The length of stay in hospital for patients with a Gustilo-Anderson
grade IIIB fracture was twice as long as for less severe injuries. . Conclusion. Fractures in children heal better than those in adults. Based
on our experience of deep infection we discourage the use of internal
fixation with a plate for
Aims. The management of open lower limb fractures in the United Kingdom
has evolved over the last ten years with the introduction of major
trauma networks (MTNs), the publication of standards of care and
the wide acceptance of a combined orthopaedic and plastic surgical approach

The continual cycle of bone formation and resorption
is carried out by osteoblasts, osteocytes, and osteoclasts under
the direction of the bone-signaling pathway. In certain situations
the host cycle of bone repair is insufficient and requires the assistance
of bone grafts and their substitutes. The fundamental properties
of a bone graft are osteoconduction, osteoinduction, osteogenesis,
and structural support. Options for bone grafting include autogenous
and allograft bone and the various isolated or combined substitutes
of calcium sulphate, calcium phosphate, tricalcium phosphate, and
coralline hydroxyapatite. Not all bone grafts will have the same
properties. As a result, understanding the requirements of the clinical
situation and specific properties of the various types of bone grafts
is necessary to identify the ideal graft. We present a review of
the bone repair process and properties of bone grafts and their
substitutes to help guide the clinician in the decision making process. Cite this article:
In this study we quantified and characterised
the return of functional mobility following open tibial fracture
using the Hamlyn Mobility Score. A total of 20 patients who had
undergone reconstruction following this fracture were reviewed at
three-month intervals for one year. An ear-worn movement sensor
was used to assess their mobility and gait. The Hamlyn Mobility
Score and its constituent kinematic features were calculated longitudinally,
allowing analysis of mobility during recovery and between patients
with varying grades of fracture. The mean score improved throughout
the study period. Patients with more severe fractures recovered
at a slower rate; those with a grade I Gustilo-Anderson fracture
completing most of their recovery within three months, those with
a grade II fracture within six months and those with a grade III
fracture within nine months. Analysis of gait showed that the quality of walking continued
to improve up to 12 months post-operatively, whereas the capacity
to walk, as measured by the six-minute walking test, plateaued after
six months. Late complications occurred in two patients, in whom the trajectory
of recovery deviated by >
0.5 standard deviations below that of
the remaining patients. This is the first objective, longitudinal
assessment of functional recovery in patients with an open tibial
fracture, providing some clarification of the differences in prognosis
and recovery associated with different grades of fracture. Cite this article:
We report the outcome of 84 nonunions involving
long bones which were treated with rhBMP-7, in 84 patients (60 men:
24 women) with a mean age 46 years (18 to 81) between 2003 and 2011.
The patients had undergone a mean of three previous operations (one
to 11) for nonunion which had been present for a mean of 17 months
(4 months to 20 years). The nonunions involved the lower limb in
71 patients and the remainder involved the upper limb. A total of 30
nonunions were septic. Treatment was considered successful when
the nonunion healed without additional procedures. The relationship
between successful union and the time to union was investigated
and various factors including age and gender, the nature of the
nonunion (location, size, type, chronicity, previous procedures,
infection, the condition of the soft tissues) and type of index
procedure (revision of fixation, type of graft, amount of rhBMP-7) were
analysed. The improvement of the patients’ quality of life was estimated
using the Short Form (SF) 12 score. A total of 68 nonunions (80.9%) healed with no need for further
procedures at a mean of 5.4 months (3 to 10) post-operatively. Multivariate
logistic regression analysis of the factors affecting union suggested
that only infection significantly affected the rate of union
(p = 0.004).Time to union was only affected by the number of previous
failed procedures
(p = 0.006). An improvement of 79% and 32.2% in SF-12 physical and
mental score, respectively, was noted within the first post-operative
year. Rh-BMP-7 combined with bone grafts, enabled healing of the nonunion
and improved quality of life in about 80% of patients. Aseptic nonunions
were much more likely to unite than septic ones. The number of previous
failed operations significantly delayed the time to union. Cite this article:
Infected nonunion of a long bone continues to
present difficulties in management. In addition to treating the infection,
it is necessary to establish bony stability, encourage fracture
union and reconstruct the soft-tissue envelope. We present a series of 67 infected nonunions of a long bone in
66 patients treated in a multidisciplinary unit. The operative treatment
of patients suitable for limb salvage was performed as a single
procedure. Antibiotic regimes were determined by the results of
microbiological culture. At a mean follow-up of 52 months (22 to 97), 59 patients (88%)
had an infection-free united fracture in a functioning limb. Seven
others required amputation (three as primary treatment, three after
late failure of limb salvage and one for recalcitrant pain after
union). The initial operation achieved union in 54 (84%) of the salvaged
limbs at a mean of nine months (three to 26), with recurrence of
infection in 9%. Further surgery in those limbs that remained ununited
increased the union rate to 62 (97%) of the 64 limbs treated by
limb salvage at final follow-up. The use of internal fixation was
associated with a higher risk of recurrent infection than external
fixation. Cite this article:
