The aim of the present study was to compare the 30- and 90-day
re-admission rates and complication rates of outpatient and inpatient
total shoulder arthroplasty (TSA). The United States Medicare Standard Analytical Files database
was questioned to identify patients who had undergone outpatient
or inpatient TSA between 2005 and 2012. Patient characteristics
were compared between the two groups using chi-squared analysis. Multivariate
logistic regression analysis was used to control for differences
in baseline patient characteristics and to compare the two groups
in terms of post-operative complications within 90 days and re-admission
within 30 days and 90 days.Aims
Patients and Methods
Different methods of anterior cruciate ligament (ACL) reconstruction
have been described for skeletally immature patients before closure
of the growth plates. However, the outcome and complications following
this treatment remain unclear. The aim of this systematic review
was to analyse the outcome and complications of different techniques
which may be used for reconstruction of the ACL in these patients. We performed a systematic review of the literature according
to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines. This involved a comprehensive search of PubMed, Medline,
CINAHL, Cochrane, Embase and Google Scholar databases using the
following combinations of keywords, “knee”, “anterior cruciate ligament”,
“reconstruction”, “injury”, “children”, “adolescent”, “skeletally
immature”, “open physis” and “surgery”.Aims
Materials and Methods
The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures. Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared.Objectives
Methods
Our aim in this study was to describe the long-term survival
of the native hip joint after open reduction and internal fixation
of a displaced fracture of the acetabulum. We also present long-term
clinical outcomes and risk factors associated with a poor outcome. A total of 285 patients underwent surgery for a displaced acetabular
fracture between 1993 and 2005. For the survival analysis 253 were
included, there were 197 men and 56 women with a mean age of 42
years (12 to 78). The mean follow-up of 11 years (1 to 20) was identified
from our pelvic fracture registry. There were 99 elementary and 154
associated fracture types. For the long-term clinical follow-up,
192 patients with complete data were included. Their mean age was
40 years (13 to 78) with a mean follow-up of 12 years (5 to 20).
Injury to the femoral head and acetabular impaction were assessed
with CT scans and patients with an ipsilateral fracture of the femoral
head were excluded.Aims

The June 2015 Wrist &
Hand Roundup360 looks at: Collagenase and Dupuytren’s disease – a genuine alternative to surgery?; iPad PROMise?; Should we learn how to do endoscopic carpal tunnel release?; Two-week radiographs a relic of the past?; Bible? Aspirate or excise?; Patient expectations and trapeziometacarpal osteoarthritis; Splintage in the treatment of sagittal band incompetence and extensor tendon subluxation
The aim of this study was to evaluate the long-term clinical
and radiographic outcomes of the Birmingham Interlocking Pelvic
Osteotomy (BIPO). In this prospective study, we report the mid- to long-term clinical
outcomes of the first 100 consecutive patients (116 hips; 88 in
women, 28 in men) undergoing BIPO, reflecting the surgeon’s learning
curve. Failure was defined as conversion to hip arthroplasty. The
mean age at operation was 31 years (7 to 57). Three patients (three
hips) were lost to follow-up.Aims
Patients and Methods
Cellular movement and relocalisation are important for many physiologic properties. Local mesenchymal stem cells (MSCs) from injured tissues and circulating MSCs aid in fracture healing. Cytokines and chemokines such as Stromal cell-derived factor 1(SDF-1) and its receptor chemokine receptor type 4 (CXCR4) play important roles in maintaining mobilisation, trafficking and homing of stem cells from bone marrow to the site of injury. We investigated the differences in migration of MSCs from the femurs of young, adult and ovariectomised (OVX) rats and the effect of CXCR4 over-expression on their migration. MSCs from young, adult and OVX rats were put in a Boyden chamber to establish their migration towards SDF-1. This was compared with MSCs transfected with CXCR4, as well as MSCs differentiated to osteoblasts.Objectives
Methods
Cubitus varus is the most frequent complication
following the treatment of supracondylar humeral fractures in children.
We investigated data from publications reporting on the surgical
management of cubitus varus found in electronic searches of Ovid/MEDLINE
and Cochrane Library databases. In 894 children from 40 included
studies, the mean age at initial injury was 5.7 years (3 to 8.6)
and 9.8 years (4 to 15.7) at the time of secondary correction. The four
osteotomy techniques were classified as lateral closing wedge, dome,
complex (multiplanar) and distraction osteogenesis. A mean angular
correction of 27.6º (18.5° to 37.0°) was achieved across all classes
of osteotomy. The meta-analytical summary estimate for overall rate
of good to excellent results was 87.8% (95% CI 84.4 to 91.2). No technique
was shown to significantly affect the surgical outcome, and the
risk of complications across all osteotomy classes was 14.5% (95%
CI 10.6 to 18.5). Nerve palsies occurred in 2.53% of cases (95%
CI 1.4 to 3.6), although 78.4% were transient. No one technique
was found to be statistically safer or more effective than any other. Cite this article:
The management of children’s fractures has evolved
as a result of better health education, changes in lifestyle, improved
implant technology and the changing expectations of society. This
review focuses on the changes seen in paediatric fractures, including
epidemiology, the increasing problems of obesity, the mechanisms
of injury, non-accidental injuries and litigation. We also examine
the changes in the management of fractures at three specific sites:
the supracondylar humerus, femoral shaft and forearm. There has
been an increasing trend towards surgical stabilisation of these
fractures. The reasons for this are multifactorial, including societal
expectations of a perfect result and reduced hospital stay. Reduced hospital
stay is beneficial to the social, educational and psychological
needs of the child and beneficial to society as a whole, due to
reduced costs. Cite this article:
Sciatic nerve palsy following total hip arthroplasty
(THA) is a relatively rare yet potentially devastating complication.
The purpose of this case series was to report the results of patients
with a sciatic nerve palsy who presented between 2000 and 2010,
following primary and revision THA and were treated with neurolysis.
A retrospective review was made of 12 patients (eight women and
four men), with sciatic nerve palsy following THA. The mean age
of the patients was 62.7 years (50 to 72; standard deviation 6.9).
They underwent interfascicular neurolysis for sciatic nerve palsy,
after failing a trial of non-operative treatment for a minimum of
six months. Following surgery, a statistically and clinically significant
improvement in motor function was seen in all patients. The mean
peroneal nerve score function improved from 0.42 (0 to 3) to 3 (1
to 5) (p <
0.001). The mean tibial nerve motor function score
improved from 1.75 (1 to 4) to 3.92 (3 to 5) (p = 0.02).The mean
improvement in sensory function was a clinically negligible 1 out
of 5 in all patients. In total, 11 patients reported improvement
in their pain following surgery. We conclude that neurolysis of the sciatic nerve has a favourable
prognosis in patients with a sciatic nerve palsy following THA.
Our findings suggest that surgery should not be delayed for >
12
months following injury. Cite this article:
Multimodal infiltration of local anaesthetic provides effective
control of pain in patients undergoing total knee arthroplasty (TKA).
There is little information about the added benefits of posterior
capsular infiltration (PCI) using different combinations of local
anaesthetic agents. Our aim was to investigate the effectiveness
of the control of pain using multimodal infiltration with and without
infiltration of the posterior capsule of the knee. In a double-blind, randomised controlled trial of patients scheduled
for unilateral primary TKA, 86 were assigned to be treated with
multimodal infiltration with (Group I) or without (Group II) PCI.
Routine associated analgesia included the use of bupivacaine, morphine,
ketorolac and epinephrine. All patients had spinal anaesthesia and patient-controlled
analgesia (PCA) post-operatively. A visual analogue scale (VAS)
for pain and the use of morphine were recorded 24 hours post-operatively.
Side effects of the infiltration, blood loss, and length of stay
in hospital were recorded.Aims
Patients and Methods
To present our experience of using a combination of intra-articular
osteotomy and external fixation to treat different deformities of
the knee. A total of six patients with a mean age of 26.5 years (15 to
50) with an abnormal hemi-joint line convergence angle (HJLCA) and
mechanical axis deviation (MAD) were included. Elevation of a tibial
hemiplateau or femoral condylar advancement was performed and limb
lengthening with correction of residual deformity using a circular
or monolateral Ilizarov frame.Aims
Patients and Methods
Nerve palsy is a well-described complication
following total hip arthroplasty, but is highly distressing and
disabling. A nerve palsy may cause difficulty with the post-operative
rehabilitation, and overall mobility of the patient. Nerve palsy
may result from compression and tension to the affected nerve(s)
during the course of the operation via surgical manipulation and
retractor placement, tension from limb lengthening or compression
from post-operative hematoma. In the literature, hip dysplasia,
lengthening of the leg, the use of an uncemented femoral component, and
female gender are associated with a greater risk of nerve palsy.
We examined our experience at a high-volume, tertiary care referral
centre, and found an overall incidence of 0.3% out of 39 056 primary
hip arthroplasties. Risk factors found to be associated with the
incidence of nerve palsy at our institution included the presence
of spinal stenosis or lumbar disc disease, age younger than 50,
and smoking. If a nerve palsy is diagnosed, imaging is mandatory
and surgical evacuation or compressive haematomas may be beneficial.
As palsies are slow to recover, supportive care such as bracing,
therapy, and reassurance are the mainstays of treatment. Cite this article:
The aim of this study was to evaluate the time course of changes
in parameters of diffusion tensor imaging (DTI) such as fractional
anisotropy (FA) and apparent diffusion coefficient (ADC) in patients
with symptomatic lumbar disc herniation. We also investigated the
correlation between the severity of neurological symptoms and these parameters. A total of 13 patients with unilateral radiculopathy due to herniation
of a lumbar disc were investigated with DTI on a 1.5T MR scanner
and underwent micro discectomy. There were nine men and four women,
with a median age of 55.5 years (19 to 79). The changes in the mean
FA and ADC values and the correlation between these changes and the
severity of the neurological symptoms were investigated before and
at six months after surgery. Aims
Patients and Methods
Periacetabular osteotomy is an effective way of treating symptomatic
hip dysplasia. We describe a new minimally invasive technique using
a modification of the Smith-Peterson approach. We performed a prospective, longitudinal cohort study to assess
for any compromise in acetabular correction when using this approach,
and to see if the procedure would have a higher complication rate
than that quoted in the literature for other approaches. We also
assessed for any improvement in functional outcome. From 168 consecutive patients (189 hips) who underwent acetabular
correction between March 2010 and March 2013 we excluded those who
had undergone previous pelvic surgery for DDH and those being treated
for acetabular retroversion. The remaining 151 patients (15 men,
136 women) (166 hips) had a mean age of 32 years (15 to 56) and the
mean duration of follow-up was 2.8 years (1.2 to 4.5). In all 90%
of cases were Tönnis grade 0 or 1. Functional outcomes were assessed
using the Non Arthritic Hip Score (NAHS), University of California,
Los Angeles (UCLA) and Tegner activity scores.Aims
Patients and Methods
Osteophytes are products of active endochondral and intramembranous ossification, and therefore could theoretically provide significant efficacy as bone grafts. In this study, we compared the bone mineralisation effectiveness of osteophytes and cancellous bone, including their effects on secretion of growth factors and anabolic effects on osteoblasts. Osteophytes and cancellous bone obtained from human patients were transplanted onto the calvaria of severe combined immunodeficient mice, with Calcein administered intra-peritoneally for fluorescent labelling of bone mineralisation. Conditioned media were prepared using osteophytes and cancellous bone, and growth factor concentration and effects of each graft on proliferation, differentiation and migration of osteoblastic cells were assessed using enzyme-linked immunosorbent assays, MTS ((3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium)) assays, quantitative real-time polymerase chain reaction, and migration assays.Objectives
