The current pandemic caused by COVID-19 is the biggest challenge for national health systems for a century. While most medical resources are allocated to treat COVID-19 patients, several non-COVID-19 medical emergencies still need to be treated, including vertebral fractures and spinal cord compression. The aim of this paper is to report the early experience and an organizational protocol for emergency spinal surgery currently being used in a large metropolitan area by an integrated team of orthopaedic surgeons and neurosurgeons. An organizational model is presented based on case centralization in hub hospitals and early management of surgical cases to reduce hospital stay. Data from all the patients admitted for emergency spinal surgery from the beginning of the outbreak were prospectively collected and compared to data from patients admitted for the same reason in the same time span in the previous year, and treated by the same integrated team.Aims
Methods
There is inconsistent evidence on whether prior spinal fusion surgery adversely impacts outcomes following total hip arthroplasty (THA). We conducted a systematic review and meta-analysis to assess the association between pre-existing spinal fusion surgery and the rate of complications following primary THA. We searched MEDLINE, Embase, Web of Science, and Cochrane Library up to October 2019 for randomized controlled trials (RCTs) and observational studies comparing outcomes of dislocation, revision, or reasons for revision in patients following primary THA with or without pre-existing spinal fusion surgery. Furthermore, we compared short (two or less levels) or long (three or more levels) spinal fusions to no fusion. Summary measures of association were relative risks (RRs) (with 95% confidence intervals (CIs)).Aims
Methods
The surgical treatment of tuberculosis (TB) of the spine consists
of debridement and reconstruction of the anterior column. Loss of
correction is the most significant challenge. Our aim was to report
the outcome of single-stage posterior surgery using bone allografts
in the management of this condition. The study involved 24 patients with thoracolumbar TB who underwent
single-stage posterior spinal surgery with a cortical bone allograft
for anterior column reconstruction and posterior instrumentation
between 2008 and 2015. A unilateral approach was used for 21 patients
with active TB, and a bilateral approach with decompression and closing-opening
wedge osteotomy was used for three patients with healed TB.Aims
Patients and Methods
To analyze outcomes reported in trials of childhood fractures. OVID MEDLINE, Embase, and Cochrane CENTRAL databases were searched on the eighth August 2019. A manual search of trial registries, bibliographic review and internet search was used to identify additional studies. 11,476 studies were screened following PRISMA guidelines. 100 trials were included in the analysis. Data extraction was completed by two researchers for each trial. Study quality was not evaluated. Outcomes reported by trials were mapped onto domains in the World Health Organization (WHO) International Classification of Function framework.Aims
Methods
To systematically review the outcomes and complications of cosmetic stature lengthening. PubMed and Embase were searched on 10 November 2019 by three reviewers independently, and all relevant studies in English published up to that date were considered based on predetermined inclusion/exclusion criteria. The search was done using “cosmetic lengthening” and “stature lengthening” as key terms. The Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement was used to screen the articles.Aims
Methods
Using a simple classification method, we aimed to estimate the collapse rate due to osteonecrosis of the femoral head (ONFH) in order to develop treatment guidelines for joint-preserving surgeries. We retrospectively analyzed 505 hips from 310 patients (141 men, 169 women; mean age 45.5 years Objectives
Methods
The aim of this study was to evaluate the outcome of spinal instrumentation in haemodialyzed patients with native pyogenic spondylodiscitis. Spinal instrumentation in these patients can be dangerous due to rates of complications and mortality, and biofilm formation on the instrumentation. A total of 134 haemodialyzed patients aged more than 50 years who underwent surgical treatment for pyogenic spondylodiscitis were included in the study. Their mean age was 66.4 years (50 to 83); 66 were male (49.3%) and 68 were female (50.7%). They were divided into two groups according to whether spinal instrumentation was used or not. Propensity score matching was used to attenuate the potential selection bias. The outcome of treatment was compared between these two groups.Aims
Patients and Methods
We performed a retrospective, comparative study of elderly patients
with an increased risk from anaesthesia who had undergone either
anterior screw fixation (ASF) or halo vest immobilisation (HVI)
for a type II odontoid fracture. A total of 80 patients aged 65 years or more who had undergone
either ASF or HVI for a type II odontoid fracture between 1988 and
2013 were reviewed. There were 47 women and 33 men with a mean age
of 73 (65 to 96; standard deviation 7). All had an American Society
of Anesthesiologists score of 2 or more.Aims
Patients and Methods
Tuberculosis (TB) infection of bones and joints accounts for
6.7% of TB cases in England, and is associated with significant
morbidity and disability. Public Health England reports that patients
with TB experience delays in diagnosis and treatment. Our aims were
to determine the demographics, presentation and investigation of
patients with a TB infection of bones and joints, to help doctors
assessing potential cases and to identify avoidable delays. This was a retrospective observational study of all adults with
positive TB cultures on specimens taken at a tertiary orthopaedic
centre between June 2012 and May 2014. A laboratory information
system search identified the patients. The demographics, clinical presentation,
radiology, histopathology and key clinical dates were obtained from
medical records.Aims
Patients and Methods
Previously, we reported the improved transfection efficiency of a plasmid DNA-chitosan (pDNA-CS) complex using a phosphorylatable nuclear localization signal-linked nucleic kinase substrate short peptide (pNNS) conjugated to chitosan (pNNS-CS). This study investigated the effects of pNNS-CS-mediated miR-140 and interleukin-1 receptor antagonist protein (IL-1Ra) gene transfection both in rabbit chondrocytes and a cartilage defect model. The pBudCE4.1-miR-140, pBudCE4.1-IL-1Ra, and negative control pBudCE4.1 plasmids were constructed and combined with pNNS-CS to form pDNA/pNNS-CS complexes. These complexes were transfected into chondrocytes or injected into the knee joint cavity.Objectives
Methods
The aim of this meta-analysis was to assess the safety and efficacy
of collagenase clostridium histolyticum compared with fasciectomy
and percutaneous needle fasciotomy (PNF) for Dupuytren’s disease. We systematically searched PubMed, EMBASE, LILACS, Web of Science,
Cochrane, Teseo and the ClinicalTrials.gov registry for clinical
trials and cohort or case-control studies which compared the clinical
outcomes and adverse effects of collagenase with those of fasciectomy
or PNF. Of 1345 articles retrieved, ten were selected. They described
the outcomes of 425 patients treated with collagenase and 418 treated
by fasciectomy or PNF. Complications were assessed using inverse-variance
weighted odds ratios (ORs). Clinical efficacy was assessed by differences
between the means for movement of the joint before and after treatment.
Dose adjustment was applied in all cases.Aims
Materials and Methods
Surgeons face a substantial risk of infection because of the occupational exposure to blood-borne pathogens (BBPs) from patients undergoing high-risk orthopaedic procedures. This study aimed to determine the seroprevalence of four BBPs among patients undergoing joint arthroplasty in Shanghai, China. In addition, we evaluated the significance of pre-operative screening by calculating a cost-to-benefit ratio. A retrospective observational study of pre-operative screening for BBPs, including hepatitis B and C viruses (HBV and HCV), human immunodeficiency virus (HIV) and Treponema pallidum (TP), was conducted for sequential patients in the orthopaedic department of a large urban teaching hospital between 01 January 2009 and 30 May 2016. Medical records were analysed to verify the seroprevalence of these BBPs among the patients stratified by age, gender, local origin, type of surgery, history of previous transfusion and marital status.Objectives
Methods
We reviewed all patients who sustained a fracture of the hip
and were treated in Northern Ireland over a period of 15 years to
identify trends in incidence, the demographics of the patients,
the rates of mortality, the configuration of the fracture and the
choice of implant. Since 01 January 2001 data about every fracture of the hip sustained
in an adult have been collected centrally in Northern Ireland. All
adults with such a fracture between 2000 and 2015 were included
in the study. Temporal changes in their demographics, the mode of
treatment, and outcomes including mortality were analysed.Aims
Patients and Methods
Hip hemiarthroplasty is a standard treatment for intracapsular
proximal femoral fractures in the frail elderly. In this study we
have explored the implications of early return to theatre, within
30 days, on patient outcome following hip hemiarthroplasty. We retrospectively reviewed the hospital records of all hip hemiarthroplasties
performed in our unit between January 2010 and January 2015. Demographic
details, medical backround, details of the primary procedure, complications,
subsequent procedures requiring return to theatre, re-admissions,
discharge destination and death were collected.Aims
Patients and Methods
There is no consensus about the best method of achieving equal
leg lengths at total hip arthroplasty (THA) in patients with Crowe
type-IV developmental dysplasia of the hip (DDH). We reviewed our
experience of a consecutive series of patients who underwent THA
for this indication. We retrospectively reviewed 78 patients (86 THAs) with Crowe
type-IV DDH, including 64 women and 14 men, with a minimum follow-up
of two years. The mean age at the time of surgery was 52.2 years
(34 to 82). We subdivided Crowe type-IV DDH into two major types
according to the number of dislocated hips, and further categorised
them into three groups according to the occurrence of pelvic obliquity
or spinal curvature. Leg length discrepancy (LLD) and functional
scores were analysed.Aims
Patients and Methods
The purpose of this study was to evaluate and
compare the effect of short segment pedicle screw instrumentation and
an intermediate screw (SSPI+IS) on the radiological outcome of type
A thoracolumbar fractures, as judged by the load-sharing classification,
percentage canal area reduction and remodelling. We retrospectively evaluated 39 patients who had undergone hyperlordotic
SSPI+IS for an AO-Magerl Type-A thoracolumbar fracture. Their mean
age was 35.1 (16 to 60) and the mean follow-up was 22.9 months (12
to 36). There were 26 men and 13 women in the study group. In total,
18 patients had a load-sharing classification score of seven and
21 a score of six. All radiographs and CT scans were evaluated for
sagittal index, anterior body height compression (%ABC), spinal
canal area and encroachment. There were no significant differences
between the low and high score groups with respect to age, duration
of follow-up, pre-operative sagittal index or pre-operative anterior
body height compression (p = 0.217, 0.104, 0.104, and 0.109 respectively).
The mean pre-operative sagittal index was 19.6° (12° to 28°) which
was corrected to -1.8° (-5° to 3°) post-operatively and 2.4° (0°
to 8°) at final follow-up (p = 0.835 for sagittal deformity). No
patient needed revision for loss of correction or failure of instrumentation. Hyperlordotic reduction and short segment pedicle screw instrumentation
and an intermediate screw is a safe and effective method of treating
burst fractures of the thoracolumbar spine. It gives excellent radiological
results with a very low rate of failure regardless of whether the
fractures have a high or low load-sharing classification score. Cite this article
A total of 22 patients with a tibial avulsion
fracture involving the insertion of the posterior cruciate ligament
(PCL) with grade II or III posterior laxity were reduced and fixed
arthroscopically using routine anterior and double posteromedial
portals. A double-strand Ethibond suture was inserted into the joint
and wrapped around the PCL from anterior to posterior to secure
the ligament above the avulsed bony fragment. Two tibial bone tunnels
were created using the PCL reconstruction guide, aiming at the medial
and lateral borders of the tibial bed. The ends of the suture were
pulled out through the bone tunnels and tied over the tibial cortex
between the openings of the tunnels to reduce and secure the bony
fragment. Satisfactory reduction of the fracture was checked arthroscopically and
radiographically. The patients were followed-up for a mean of 24.5 months (19 to
28). Bone union occurred six weeks post-operatively. At final follow-up,
all patients had a negative posterior drawer test and a full range
of movement. KT-1000 arthrometer examination showed that the mean
post-operative side-to-side difference improved from 10.9 mm (standard
deviation ( We conclude that this technique is convenient, reliable and minimally
invasive and successfully restores the stability and function of
the knee. Cite this article:
Medium-term survivorship of the Oxford phase
3 unicompartmental knee replacement (UKR) has not yet been established
in an Asian population. We prospectively evaluated the outcome of
400 phase 3 Oxford UKRs in 320 Korean patients with a mean age at
the time of operation of 69 years (48 to 82). The mean follow-up
was 5.2 years (1 to 10). Clinical and radiological assessment was
carried out pre- and post-operatively. At five years, the mean Knee
Society knee and functional scores had increased significantly from
56.2 (30 to 91) pre-operatively to 87.2 (59 to 98) (p = 0.034) and
from 59.2 (30 to 93) to 88.3 (50 to 100) (p = 0.021), respectively.
The Oxford knee score increased from a mean of 25.8 (12 to 39) pre-operatively
to 39.8 (25 to 58) at five years (p = 0.038). The ten-year survival
rate was 94% (95% confidence interval 90.1 to 98.0). A total of
14 UKRs (3.5%) required revision. The most common reason for revision
was dislocation of the bearing in 12 (3%). Conversion to a total
knee replacement was required in two patients who developed osteoarthritis
of the lateral compartment. This is the largest published series of UKR in Korean patients.
It shows that the mid-term results after a minimally invasive Oxford
phase 3 UKR can yield satisfactory clinical and functional results
in this group of patients.
