Current studies on the additional benefit of using computed tomography
(CT) in order to evaluate the surgeons’ agreement on treatment plans
for fracture are inconsistent. This inconsistency can be explained
by a methodological phenomenon called ‘spectrum bias’, defined as
the bias inherent when investigators choose a population lacking
therapeutic uncertainty for evaluation. The aim of the study is
to determine the influence of spectrum bias on the intra-observer
agreement of treatment plans for fractures of the distal radius. Four surgeons evaluated 51 patients with displaced fractures
of the distal radius at four time points: T1 and T2: conventional
radiographs; T3 and T4: radiographs and additional CT scan (radiograph
and CT). Choice of treatment plan (operative or non-operative) and
therapeutic certainty (five-point scale: very uncertain to very
certain) were rated. To determine the influence of spectrum bias,
the intra-observer agreement was analysed, using Kappa statistics,
for each degree of therapeutic certainty. Objectives
Methods
This study investigates and defines the topographic
anatomy of the medial femoral circumflex artery (MFCA) terminal
branches supplying the femoral head (FH). Gross dissection of 14
fresh–frozen cadaveric hips was undertaken to determine the extra
and intracapsular course of the MFCA’s terminal branches. A constant
branch arising from the transverse MFCA (inferior retinacular artery;
IRA) penetrates the capsule at the level of the anteroinferior neck,
then courses obliquely within the fibrous prolongation of the capsule
wall (inferior retinacula of Weitbrecht), elevated from the neck,
to the posteroinferior femoral head–neck junction. This vessel has
a mean of five (three to nine) terminal branches, of which the majority
penetrate posteriorly. Branches from the ascending MFCA entered
the femoral capsular attachment posteriorly, running deep to the
synovium, through the neck, and terminating in two branches. The
deep MFCA penetrates the posterosuperior femoral capsular. Once
intracapsular, it divides into a mean of six (four to nine) terminal
branches running deep to the synovium, within the superior retinacula
of Weitbrecht of which 80% are posterior. Our study defines the
exact anatomical location of the vessels, arising from the MFCA
and supplying the FH. The IRA is in an elevated position from the
femoral neck and may be protected from injury during fracture of
the femoral neck. We present vascular ‘danger zones’ that may help
avoid iatrogenic vascular injury during surgical interventions about
the hip. Cite this article:
This study aimed to compare the change in health-related quality
of life of patients receiving a traditional cemented monoblock Thompson
hemiarthroplasty compared with a modern cemented modular polished-taper
stemmed hemiarthroplasty for displaced intracapsular hip fractures. This was a pragmatic, multicentre, multisurgeon, two-arm, parallel
group, randomized standard-of-care controlled trial. It was embedded
within the WHiTE Comprehensive Cohort Study. The sample size was
964 patients. The setting was five National Health Service Trauma
Hospitals in England. A total of 964 patients over 60 years of age who
required hemiarthroplasty of the hip between February 2015 and March
2016 were included. A standardized measure of health outcome, the
EuroQol (EQ-5D-5L) questionnaire, was carried out on admission and
at four months following the operation.Aims
Patients and Methods
We compared the accuracy, operating time and radiation exposure
of the introduction of iliosacral screws using O-arm/Stealth Navigation
and standard fluoroscopy. Iliosacral screws were introduced percutaneously into the first
sacral body (S1) of ten human cadavers, four men and six women.
The mean age was 77 years (58 to 85). Screws were introduced using
a standard technique into the left side of S1 using C-Arm fluoroscopy
and then into the right side using O-Arm/Stealth Navigation. The
radiation was measured on the surgeon by dosimeters placed under
a lead thyroid shield and apron, on a finger, a hat and on the cadavers.Aims
Materials and Methods
Our aim, using English Hospital Episode Statistics data before
during and after the Distal Radius Acute Fracture Fixation Trial
(DRAFFT), was to assess whether the results of the trial affected
clinical practice. Data were grouped into six month intervals from July 2005 to
December 2014. All patient episodes in the National Health Service
involving emergency surgery for an isolated distal radial fracture
were included.Aims
Patients and Methods
Hemiarthroplasty of the hip is usually carried out through either
a direct lateral or posterior approach. The aim of this prospective
observational study was to determine any differences in patient-reported
outcomes between the two surgical approaches. From the Swedish Hip Arthroplasty Register we identified patients
of 70 years and above who were recorded as having had a hemiarthroplasty
during 2009. Only patients who had been treated with modern prostheses
were included. A questionnaire was posted to those who remained
alive one year after surgery. A total of 2118 patients (78% of those
available) with a mean age of 85 years (70 to 102) returned the
questionnaire. Aims
Patients and Methods
The PROximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial has recently demonstrated that surgery is non-superior to non-operative treatment in the management of displaced proximal humeral fractures. The objective of this study was to assess current surgical practice in the context of the PROFHER trial in terms of patient demographics, injury characteristics and the nature of the surgical treatment. A total of ten consecutive patients undergoing surgery for the treatment of a proximal humeral fracture from each of 11 United Kingdom hospitals were retrospectively identified over a 15 month period between January 2014 and March 2015. Data gathered for the 110 patients included patient demographics, injury characteristics, mode of surgical fixation, the grade of operating surgeon and the cost of the surgical implants.Objectives
Methods
Our aim was to investigate the outcomes of patients with a displaced
fracture of the glenoid fossa who are treated conservatively. There
is little information in the literature about the treatment of these
rare injuries non-operatively. We reviewed 24 patients with a mean age of 52 years (19 to 81)
at a mean of 5.6 years (11 months to 18 years) after the injury.Aims
Patients and Methods
Our aim was to examine the clinical and radiographic outcomes
in 257 consecutive Oxford unicompartmental knee arthroplasties (OUKAs)
(238 patients), five years post-operatively. A retrospective evaluation was undertaken of patients treated
between April 2008 and October 2010 in a regional centre by two
non-designing surgeons with no previous experience of UKAs. The
Oxford Knee Scores (OKSs) were recorded and fluoroscopically aligned
radiographs were assessed post-operatively at one and five years.Aims
Patients and Methods
The aim of this study was to quantify the stability
of fracture-implant complex in fractures after fixation. A total
of 15 patients with an undisplaced fracture of the femoral neck,
treated with either a dynamic hip screw or three cannulated hip
screws, and 16 patients with an AO31-A2 trochanteric fracture treated
with a dynamic hip screw or a Gamma Nail, were included. Radiostereometric
analysis was used at six weeks, four months and 12 months post-operatively
to evaluate shortening and rotation. Migration could be assessed in ten patients with a fracture of
the femoral neck and seven with a trochanteric fracture. By four
months post-operatively, a mean shortening of 5.4 mm (-0.04 to 16.1)
had occurred in the fracture of the femoral neck group and 5.0 mm
(-0.13 to 12.9) in the trochanteric fracture group. A wide range
of rotation occurred in both types of fracture. Right-sided trochanteric
fractures seem more rotationally stable than left-sided fractures. This prospective study shows that migration at the fracture site
occurs continuously during the first four post-operative months,
after which stabilisation occurs. This information may allow the
early recognition of patients at risk of failure of fixation. Cite this article:
We aimed to quantify the relative contributions of the medial
femoral circumflex artery (MFCA) and lateral femoral circumflex
artery (LFCA) to the arterial supply of the head and neck of the
femur. We acquired ten cadaveric pelvises. In each of these, one hip
was randomly assigned as experimental and the other as a matched
control. The MFCA and LFCA were cannulated bilaterally. The hips
were designated LFCA-experimental or MFCA-experimental and underwent
quantitative MRI using a 2 mm slice thickness before and after injection
of MRI-contrast diluted 3:1 with saline (15 ml Gd-DTPA) into either
the LFCA or MFCA. The contralateral control hips had 15 ml of contrast
solution injected into the root of each artery. Next, the MFCA and
LFCA were injected with a mixture of polyurethane and barium sulfate
(33%) and their extra-and intra-arterial course identified by CT
imaging and dissection.Aims
Materials and Methods
We define the long-term outcomes and rates of
further operative intervention following displaced Bennett’s fractures
treated with Kirschner (K-) wire fixation between 1996 and 2009.
We retrospectively identified 143 patients (127 men and 16 women)
with a mean age at the time of injury of 33.2 years (18 to 75).
Electronic records were examined and patients were invited to complete
the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire
in addition to a satisfaction questionnaire. The time since injury
was a mean of 11.5 years (3.4 to 18.5). In total 11 patients had
died, one had developed dementia and 12 patients were lost to follow-up.
This left 119 patients available for recruitment. Of these, 57 did
not respond, leaving a study group of 62 patients. Patients reported
excellent functional outcomes and high levels of satisfaction at
follow-up. Median satisfaction was 94% (interquartile range 91.5
to 97.5) and the mean DASH score was 3.0 (0 to 38). None of the patients
had undergone salvage procedures and none of the responders had
changed occupation or sporting activities. Long-term patient reported
outcomes following displaced Bennett’s fractures treated by closed
reduction and K-wire fixation show excellent functional results
and a high level of patient satisfaction. The rate of infection
is low and similar to other surgical procedures with percutaneous
K-wires. Cite this article:
Patients with diabetes are at increased risk of wound complications
after open reduction and internal fixation of unstable ankle fractures.
A fibular nail avoids large surgical incisions and allows anatomical
reduction of the mortise. We retrospectively reviewed the results of fluoroscopy-guided
reduction and percutaneous fibular nail fixation for unstable Weber
type B or C fractures in 24 adult patients with type 1 or type 2
diabetes. The re-operation rate for wound dehiscence or other indications
such as amputation, mortality and functional outcomes was determined.Aims
