The aims of this study were to establish whether composite fixation
(rail-plate) decreases fixator time and related problems in the
management of patients with infected nonunion of tibia with a segmental
defect, without compromising the anatomical and functional outcomes
achieved using the classical Ilizarov technique. We also wished
to study the acceptability of this technique using patient-based
objective criteria. Between January 2012 and January 2015, 14 consecutive patients
were treated for an infected nonunion of the tibia with a gap and
were included in the study. During stage one, a radical debridement
of bone and soft tissue was undertaken with the introduction of
an antibiotic-loaded cement spacer. At the second stage, the tibia
was stabilized using a long lateral locked plate and a six-pin monorail
fixator on its anteromedial surface. A corticotomy was performed
at the appropriate level. During the third stage, i.e. at the end
of the distraction phase, the transported fragment was aligned and
fixed to the plate with two to four screws. An iliac crest autograft
was added to the docking site and the fixator was removed. Functional
outcome was assessed using the Association for the Study and Application
of Methods of Ilizarov (ASAMI) criteria. Patient-reported outcomes
were assessed using the Musculoskeletal Tumor Society (MSTS) score.Aims
Patients and Methods
1. Intramedullary nailing in two-level tibial fractures provides the following advantages: it allows walking with full weight-bearing in an average time ofthree to four months; it decreases the rate of non-union ; it decreases the rate of malunion ; it should decrease the rate of
The aim of this study was to identify predictors of return to
work (RTW) after revision lower limb arthroplasty in patients of
working age in the United Kingdom. We assessed 55 patients aged ≤ 65 years after revision total
hip arthroplasty (THA). There were 43 women and 12 men with a mean
age of 54 years (23 to 65). We also reviewed 30 patients after revision
total knee arthroplasty (TKA). There were 14 women and 16 men with
a mean age of 58 years (48 to 64). Preoperatively, age, gender,
body mass index, social deprivation, mode of failure, length of
primary implant survival, work status and nature, activity level
(University of California, Los Angeles (UCLA) score), and Oxford
Hip and Knee Scores were recorded. Postoperatively, RTW status,
Oxford Hip and Knee Scores, EuroQol-5D (EQ-5D), UCLA score, and
Work, Osteoarthritis and Joint-Replacement Questionnaire (WORQ)
scores were obtained. Univariate and multivariate analysis was performed.Aims
Patients and Methods
There are no recent studies comparing cable with
wire for the fixation of osteotomies or fractures in total hip replacement
(THR). Our objective was to evaluate the five-year clinical and
radiological outcomes and complication rates of the two techniques.
We undertook a review including all primary and revision THRs performed
in one hospital between 1996 and 2005 using cable or wire fixation.
Clinical and radiological evaluation was performed five years post-operatively.
Cables were used in 51 THRs and wires in 126, and of these, 36 THRs
with cable (71%) and 101 with wire (80%) were evaluated at follow-up.
The five-year radiographs available for 33 cable and 91 wire THRs
revealed rates of breakage of fixation of 12 of 33 (36%) and 42
of 91 (46%), respectively. With cable there was a significantly
higher risk of metal debris (68% vs 9%; adjusted
relative risk (RR) 6.6; 95% confidence interval (CI) 3.0 to 14.1),
nonunion (36% vs 21%; adjusted RR 2.0; 95% CI 1.0
to 3.9) and osteolysis around the material, acetabulum or femur
(61% vs 19%; adjusted RR 3.9; 95% CI 2.3 to 6.5).
Cable breakage increased the risk of osteolysis to 83%. There
was a trend towards foreign-body reaction and increased infection
with cables. Clinical results did not differ between the groups. In conclusion, we found a higher incidence of complications and
a trend towards increased

From 1984 to 1988 we implanted 127 massive allografts irradiated with a dose of 25,000 grays. These were reviewed at a minimum follow-up of three years to determine the effect of irradiation on
We investigated the efficacy of a single dose of 1 g of cephazolin in reducing postoperative
Previous studies have suggested that metal-on-metal (MoM) Pinnacle (DePuy Synthes, Warsaw, Indiana) hip arthroplasties implanted after 2006 exhibit higher failure rates. This was attributed to the production of implants with reduced diametrical clearances between their bearing surfaces, which, it was speculated, were outside manufacturing tolerances. This study aimed to better understand the performance of Pinnacle Systems manufactured before and after this event. A total of 92 retrieved MoM Pinnacle hips were analyzed, of which 45 were implanted before 2007, and 47 from 2007 onwards. The ‘pre-2007’ group contained 45 implants retrieved from 21 male and 24 female patients, with a median age of 61.3 years (interquartile range (IQR) 57.1 to 65.5); the ‘2007 onwards’ group contained 47 implants retrieved from 19 male and 28 female patients, with a median age of 61.8 years (IQR 58.5 to 67.8). The volume of material lost from their bearing and taper surfaces was measured using coordinate and roundness measuring machines. These outcomes were then compared statistically using linear regression models, adjusting for potentially confounding factors.Objectives
Methods
The aim of this study was to identify the most effective regimen
of multiple doses of oral tranexamic acid (TXA) in achieving maximum
reduction of blood loss in total knee arthroplasty (TKA). In this randomized controlled trial, 200 patients were randomized
to receive a single dose of 2.0 g of TXA orally two hours preoperatively
(group A), a single dose of TXA followed by 1.0 g orally three hours
postoperatively (group B), a single dose of TXA followed by 1.0 g
three and nine hours postoperatively (group C), or a single dose
of TXA followed by 1.0 g orally three, nine, and 15 hours postoperatively
(group D). All patients followed a routine enhanced-recovery protocol.
The primary outcome measure was the total blood loss. Secondary
outcome measures were hidden blood loss (HBL), reduction in the
level of haemoglobin, the rate of transfusion and adverse events.Aims
Patients and Methods
For this retrospective cohort study, patients aged ≤ 30 years
(very young) who underwent total hip arthroplasty (THA) were compared
with patients aged ≥ 60 years (elderly) to evaluate the rate of
revision arthroplasty, implant survival, the indications for revision,
the complications, and the patient-reported outcomes. We retrospectively reviewed all patients who underwent primary
THA between January 2000 and May 2015 from our institutional database.
A total of 145 very young and 1359 elderly patients were reviewed.
The mean follow-up was 5.3 years (1 to 18). Logistic generalized
estimating equations were used to compare characteristics and the revision
rate. Survival was evaluated using Kaplan–Meier curves and hazard
rates were created using Cox regression.Aims
Patients and Methods
In 50 patients with non-infected total hip arthroplasties (THA), 233 C-reactive protein (CRP) values were obtained over a three-year period. Six of these 50 patients occasionally had CRP values of over 20 mg/l. The erythrocyte sedimentation rate (ESR) and CRP concentration were measured in 23 patients with deep
The treatment of substantial proximal femoral
bone loss in young patients with developmental dysplasia of the
hip (DDH) is challenging. We retrospectively analysed the outcome
of 28 patients (30 hips) with DDH who underwent revision total hip
replacement (THR) in the presence of a deficient proximal femur,
which was reconstructed with an allograft prosthetic composite.
The mean follow-up was 15 years (8.5 to 25.5). The mean number of
previous THRs was three (1 to 8). The mean age at primary THR and
at the index reconstruction was 41 years (18 to 61) and 58.1 years
(32 to 72), respectively. The indication for revision included mechanical
loosening in 24 hips,
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. A total of 18 male New Zealand white rabbits underwent femoral
osteotomy with intramedullary fixation with ‘shock’ (n = 9) and
control (n = 9) groups. Shock was induced in the study group by
removal of 35% of the total blood volume 45 minutes before resuscitation
with blood and crystalloid. Fracture healing was monitored for eight weeks
using serum markers of healing and radiographs.Aims
Materials and Methods
A delay in the diagnosis of paediatric acute
and subacute haematogenous osteomyelitis can lead to potentially devastating
morbidity. There are no definitive guidelines for diagnosis, and
recommendations in the literature are generally based on expert
opinions, case series and cohort studies. All articles in the English literature on paediatric osteomyelitis
were searched using MEDLINE, CINAHL, EMBASE, Google Scholar, the
Cochrane Library and reference lists. A total of 1854 papers were
identified, 132 of which were examined in detail. All aspects of
osteomyelitis were investigated in order to formulate recommendations. On admission 40% of children are afebrile. The tibia and femur
are the most commonly affected long bones. Clinical examination,
blood and radiological tests are only reliable for diagnosis in
combination. Staphylococcus aureus is the most
common organism detected, but isolation of Kingella kingae is
increasing. Antibiotic treatment is usually sufficient to eradicate

A total of 157 hindquarter amputations were carried
out in our institution during the last 30 years. We have investigated
the reasons why this procedure is still required and the outcome.
This operation was used as treatment for 13% of all pelvic bone
sarcomas. It was curative in 140 and palliative in 17, usually to
relieve pain. There were 90 primary procedures (57%) with the remaining
67 following the failure of previous operations to control the disease
locally. The indication for amputation in primary disease was for
large tumours for which limb-salvage surgery was no longer feasible.
The peri-operative mortality was 1.3% (n = 2) and major complications

We present the extended follow-up (≥ 20 years)
of a series of fully hydroxyapatite-coated femoral components used in
72 primary total hip replacements (THRs). Earlier results of this
cohort have been previously published. All procedures were performed
between 1986 and 1991. The series involved 45 women and 15 men with
12 bilateral procedures. Their mean age at the time of surgery was
60 years (46 to 80) and the mean duration of follow-up was 22.5
years (20 to 25). At final follow-up, the mean Merle d’Aubigné and
Postel hip scores were 5.5 (4.5 to 6), 3.8 (3.5 to 5) and 3.3 (3.0
to 5.0) for pain, mobility and function, respectively. Of the patients
92% were very satisfied at the time of final follow-up. There were seven revisions: six of the acetabular component for
aseptic loosening and one of both the stem and the acetabular component
for loosening due to deep
We report ten-year clinical and radiological
follow-up data for the Sigma Press Fit Condylar total knee replacement system
(Sigma PFC TKR). Between October 1998 and October 1999 a total of
235 consecutive PFC Sigma TKRs were carried out in 203 patients.
Patients were seen at a specialist nurse-led clinic seven to ten
days before admission and at six and 18 months, three, five and
eight to ten years after surgery. Data were recorded prospectively
at each clinic visit. Radiographs were obtained at the five- and
eight- to ten-year follow-up appointments. Of the 203 patients,
147 (171 knees) were alive at ten years and 12 were lost to follow-up.
A total of eight knees (3.4%) were revised, five for
