Aims. The purpose of this exploratory study was to investigate if the 24-hour activity profile (i.e. waking activities and sleep) objectively measured using wrist-worn accelerometry of patients scheduled for total hip arthroplasty (THA) improves postoperatively. Patients and Methods. A total of 51 THA patients with a mean age of 64 years (24 to 87) were recruited from a single public hospital. All patients underwent THA using the same surgical approach with the same prosthesis type. The 24-hour activity profiles were captured using wrist-worn accelerometers preoperatively and at 2, 6, 12, and 26 weeks postoperatively. Patient-reported outcomes (Hip Disability and Osteoarthritis Outcome Score (HOOS)) were collected at all timepoints except two weeks postoperatively. Accelerometry data were used to quantify the intensity (sedentary, light, moderate, and vigorous activities) and frequency (bouts) of activity during the day and
Aims. The primary aim was to assess change in health-related quality of life (HRQoL) of patients as they waited from six to 12 months for a total hip (THA) or total or partial knee arthroplasty (KA). Secondary aims were to assess change in joint-specific function, mental health, quality of

We describe the longer term clinical and radiological findings in a prospectively followed series of 49 rheumatoid patients (58 shoulders) who had undergone Neer II total shoulder replacement. The early and intermediate results have been published previously. At a mean follow-up of 19.8 years (16.5 to 23.8) 14 shoulders survived. Proximal migration of the humeral component was associated with progressive loosening of the glenoid and humeral components, but was independent of the state of the rotator cuff at the time of operation. Despite these changes the range of movement was preserved. Most patients had little or no pain in the shoulder, could

Between 1992 and 1994 we performed a prospective study of the effect of total knee replacement (TKR) on the health status of 119 patients over the age of 80 years who had had a primary unilateral TKR. The Nottingham Health Profile was used to assess this before and at three and 12 months after operation. We found a significant improvement in the scores for pain, emotional reaction,
Despite new technologies for total knee arthroplasty (TKA), approximately 20% of patients are dissatisfied. A major reason for dissatisfaction and revision surgery after TKA is persistent pain. The radiological grade of osteoarthritis (OA) preoperatively has been investigated as a predictor of the outcome after TKA, with conflicting results. The aim of this study was to determine if there is a difference in the intensity of pain 12 months after TKA in relation to the preoperative radiological grade of OA alone, and the combination of the intensity of preoperative pain and radiological grade of OA. The preoperative data of 300 patients who underwent primary TKA were collected, including clinical information (age, sex, preoperative pain), psychological variables (depression, anxiety, pain catastrophizing, anticipated pain), and quantitative sensory testing (temporal summation, pressure pain thresholds, conditioned pain modulation). The preoperative radiological severity of OA was graded according to the Kellgren-Lawrence (KL) classification. Persistent pain in the knee was recorded 12 months postoperatively. Generalized linear models explored differences in postoperative pain according to the KL grade, and combined preoperative pain and KL grade. Relative risk models explored which preoperative variables were associated with the high preoperative pain/low KL grade group.Aims

The aim of this study was to report the patterns of symptoms and insufficiency fractures in patients with tumour-induced osteomalacia (TIO) to allow the early diagnosis of this rare condition. The study included 33 patients with TIO who were treated between January 2000 and June 2022. The causative tumour was detected in all patients. We investigated the symptoms and evaluated the radiological patterns of insufficiency fractures of the rib, spine, and limbs.Aims
Methods
The aim of this study was to describe the prevalence and patterns of neuropathic pain over one year in a cohort of patients with chronic post-surgical pain at three months following total knee arthroplasty (TKA). Between 2016 and 2019, 363 patients with troublesome pain, defined as a score of ≤ 14 on the Oxford Knee Score pain subscale, three months after TKA from eight UK NHS hospitals, were recruited into the Support and Treatment After Replacement (STAR) clinical trial. Self-reported neuropathic pain and postoperative pain was assessed at three, nine, and 15 months after surgery using the painDETECT and Douleur Neuropathique 4 (DN4) questionnaires collected by postal survey.Aims
Methods
The study aimed to assess the clinical outcomes of arthroscopic debridement and partial excision in patients with traumatic central tears of the triangular fibrocartilage complex (TFCC), and to identify prognostic factors associated with unfavourable clinical outcomes. A retrospective analysis was conducted on patients arthroscopically diagnosed with Palmer 1 A lesions who underwent arthroscopic debridement and partial excision from March 2009 to February 2021, with a minimum follow-up of 24 months. Patients were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Mayo Wrist Score (MWS), and visual analogue scale (VAS) for pain. The poor outcome group was defined as patients whose preoperative and last follow-up clinical score difference was less than the minimal clinically important difference of the DASH score (10.83). Baseline characteristics, arthroscopic findings, and radiological factors (ulnar variance, MRI, or arthrography) were evaluated to predict poor clinical outcomes.Aims
Methods
Elevated blood cobalt levels secondary to metal-on-metal (MoM) hip arthroplasties are a suggested risk factor for developing cardiovascular complications including cardiomyopathy. Clinical studies assessing patients with MoM hips using left ventricular ejection fraction (LVEF) have found conflicting evidence of cobalt-induced cardiomyopathy. Global longitudinal strain (GLS) is an echocardiography measurement known to be more sensitive than LVEF when diagnosing early cardiomyopathies. The extent of cardiovascular injury, as measured by GLS, in patients with elevated blood cobalt levels has not previously been examined. A total of 16 patients with documented blood cobalt ion levels above 13 µg/l (13 ppb, 221 nmol/l) were identified from a regional arthroplasty database. They were matched with eight patients awaiting hip arthroplasty. All patients underwent echocardiography, including GLS, investigating potential signs of cardiomyopathy.Aims
Methods
Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age. Patients aged ≥ 18 years with a traumatic CCS between January 2012 and December 2017 in Wales were identified. Patient demographics and data about injury, management, and outcome were collected. Statistical analysis was performed to assess mortality and between-group differences.Aims
Methods
The aim of this study was to investigate whether the type of cervical disc herniation influences the severity of symptoms at the time of presentation, and the outcome after surgical treatment. The type and extent of disc herniation at the time of presentation in 108 patients who underwent anterior discectomy for cervical radiculopathy were analyzed on MRI, using a four-point scale. These were dichotomized into disc bulge and disc herniation groups. Clinical outcomes were evaluated using the Neck Disability Index (NDI), 36-Item Short Form Survey (SF-36), and a visual analogue scale (VAS) for pain in the neck and arm at baseline and two years postoperatively. The perceived recovery was also assessed at this time.Aims
Methods
The aim of this study is to develop a core set of outcome domains that should be considered and reported in all future trials of childhood limb fractures. A four-phase study was conducted to agree a set of core outcome domains. Identification of candidate outcome domains were identified through systematic review of trials, and outcome domains relevant to families were identified through semi-structured interviews with 20 families (parent-child pairing or group). Outcome domains were prioritized using an international three-round Delphi survey with 205 panellists and then condensed into a core outcome set through a consensus workshop with 30 stakeholders.Aims
Methods
Although total knee arthroplasty (TKA) is a highly successful procedure, about 20% of patients remain dissatisfied postoperatively. This proportion is derived from dichotomous models of the assessment of surgical success or failure, which may not reflect the spectrum of outcomes. The aim of this study was to explore differing responses to surgery, and assess whether there are distinct groups of patients with differing patterns of outcome. This was a secondary analysis of a UK multicentre TKA longitudinal cohort study. We used a group-based trajectory modelling analysis of Oxford Knee Score (OKS) in the first year following surgery with longitudinal data involving five different timepoints and multiple predictor variables. Associations between the derived trajectory groups and categorical baseline variables were assessed, and predictors of trajectory group membership were identified using Poisson regression and multinomial logistic regression, as appropriate. The final model was adjusted for sociodemographic factors (age, sex) and baseline OKS.Aims

Proximal tibial osteotomy is commonly performed for osteoarthritis of the knee with deformity. The results of 105 dome osteotomies have been reviewed at a minimum follow-up of one year and an average of 4.8 years. Before operation all the knees were painful, 50.5% severely; a further 45.7% disturbed
The pathogenesis of Perthes' disease has been related to increased intra-articular pressure secondary to a joint effusion. The pressure within the hip in different positions was measured in eight children with transient synovitis and four with the synovial stage of Perthes' disease. In the position of comfort for the hip this pressure was always less than the arteriolar blood pressure and in a supine position it did not exceed the systolic blood pressure. However, in extension with medial rotation the intra-articular pressure always became several times the systolic blood pressure. This high pressure was also recorded in the stable lateral position which occurs normally during
Fifty-one infants with limited abduction of the hip and acetabular dysplasia were, between 1969 and 1975, treated with abduction-adduction exercises, administered by the parents; no abduction devices were used. In 1983 a follow-up examination was carried out on 41 of these patients. Although at birth these children had characteristics similar to patients with congenital dislocation of the hip, none of their hips dislocated. At birth acetabular measurements showed that half the children had severe dysplasia and the other half slight dysplasia; the difference between the affected and the healthy hips was significant. At follow-up the gait was normal in all the patients. Movements at the hips were symmetrical and within normal limits in all but one patient. The acetabular angle, the centre-edge angle, the shaft-neck angle, the hip ratio, and the size of the femoral head were the same on the previously affected side as on the normal side. Nineteen of the children followed up had preferred lying on one side and dysplasia of the upper hip had developed. The significance of the
It has been shown that the preoperative modification of risk factors associated with obesity may reduce complications after total knee arthroplasty (TKA). However, the optimal method of doing so remains unclear. The aim of this study was to investigate whether a preoperative Risk Stratification Tool (RST) devised in our institution could reduce unexpected intensive care unit (ICU) transfers and 90-day emergency department (ED) visits, readmissions, and reoperations after TKA in obese patients. We retrospectively reviewed 1,614 consecutive patients undergoing primary unilateral TKA. Their mean age was 65.1 years (17.9 to 87.7) and the mean BMI was 34.2 kg/m2 (SD 7.7). All patients underwent perioperative optimization and monitoring using the RST, which is a validated calculation tool that provides a recommendation for postoperative ICU care or increased nursing support. Patients were divided into three groups: non-obese (BMI < 30 kg/m2, n = 512); obese (BMI 30 kg/m2 to 39.9 kg/m2, n = 748); and morbidly obese (BMI > 40 kg/m2, n = 354). Logistic regression analysis was used to evaluate the outcomes among the groups adjusted for age, sex, smoking, and diabetes.Aims
Methods
This study used an artificial neural network (ANN) model to determine the most important pre- and perioperative variables to predict same-day discharge in patients undergoing total knee arthroplasty (TKA). Data for this study were collected from the National Surgery Quality Improvement Program (NSQIP) database from the year 2018. Patients who received a primary, elective, unilateral TKA with a diagnosis of primary osteoarthritis were included. Demographic, preoperative, and intraoperative variables were analyzed. The ANN model was compared to a logistic regression model, which is a conventional machine-learning algorithm. Variables collected from 28,742 patients were analyzed based on their contribution to hospital length of stay.Aims
Methods
Patients with spinal pathology who undergo total hip arthroplasty (THA) have an increased risk of dislocation and revision. The aim of this study was to determine if the use of the Hip-Spine Classification system in these patients would result in a decreased rate of postoperative dislocation in patients with spinal pathology. This prospective, multicentre study evaluated 3,777 consecutive patients undergoing THA by three surgeons, between January 2014 and December 2019. They were categorized using The Hip-Spine Classification system: group 1 with normal spinal alignment; group 2 with a flatback deformity, group 2A with normal spinal mobility, and group 2B with a stiff spine. Flatback deformity was defined by a pelvic incidence minus lumbar lordosis of > 10°, and spinal stiffness was defined by < 10° change in sacral slope from standing to seated. Each category determined a patient-specific component positioning. Survivorship free of dislocation was recorded and spinopelvic measurements were compared for reliability using intraclass correlation coefficient.Aims
Methods
Manipulation under anaesthesia (MUA) remains an effective intervention to address restricted range of motion (ROM) after total knee arthroplasty (TKA) and occurs in 2% to 3% of primary TKAs at our institution. Since there are few data on the outcomes of MUA with different anaesthetic methods, we sought to compare the outcomes of patients undergoing MUA with intravenous (IV) sedation and neuraxial anaesthesia. We identified 548 MUAs after primary TKA (136 IV sedation, 412 neuraxial anaesthesia plus IV sedation) from March 2016 to July 2019. The mean age of this cohort was 62 years (35 to 88) with a mean body mass index of 31 kg/m2 (18 to 49). The mean time from primary TKA to MUA was 10.2 weeks (6.2 to 24.3). Pre-MUA ROM was similar between groups; overall mean pre-MUA extension was 4.2° (p = 0.452) and mean pre-MUA flexion was 77° (p = 0.372). We compared orthopaedic complications, visual analogue scale (VAS) pain scores, length of stay (LOS), and immediate and three-month follow-up knee ROM between these groups.Aims
Methods
The objective of this study was to evaluate the clinical and radiological outcomes of patients younger than six months of age with developmental dysplasia of the hip (DDH) managed by either a Pavlik harness or Tübingen hip flexion splint. Records of 251 consecutive infants with a mean age of 89 days (SD 47), diagnosed with DDH between January 2015 and December 2018, were retrospectively reviewed. Inclusion criteria for patients with DDH were: younger than 180 days at the time of diagnosis; ultrasound Graf classification of IIc or greater; treatment by Pavlik harness or Tübingen splint; and no prior treatment history. All patients underwent hip ultrasound every seven days during the first three weeks of treatment and subsequently every three to four weeks until completion of treatment. If no signs of improvement were found after three weeks, the Pavlik harness or Tübingen splint was discontinued. Statistical analysis was performed.Aims
Methods
To identify a suite of the key physical, emotional, and social outcomes to be employed in clinical practice and research concerning Perthes' disease in children. The study follows the guidelines of the COMET-Initiative (Core Outcome Measures in Effectiveness Trials). A systematic review of the literature was performed to identify a list of outcomes reported in previous studies, which was supplemented by a qualitative study exploring the experiences of families affected by Perthes’ disease. Collectively, these outcomes formed the basis of a Delphi survey (two rounds), where 18 patients with Perthes’ disease, 46 parents, and 36 orthopaedic surgeons rated each outcome for importance. The International Perthes Study Group (IPSG) (Dallas, Texas, USA (October 2018)) discussed outcomes that failed to reach any consensus (either ‘in’ or ‘out’) before a final consensus meeting with representatives of surgeons, patients, and parents.Aims
Methods
To investigate whether chronic kidney disease (CKD) is associated with the risk of all-cause revision or revision due to a periprosthetic joint infection (PJI) after primary hip or knee arthroplasty. This retrospective cohort study comprised 18,979 consecutive hip and knee arthroplasties from a single high-volume academic hospital. At a median of 5.6 years (interquartile range (IQR) 3.5 to 8.1), all deaths and revisions were counted. To overcome the competing risk of death, competing risk analysis using the cumulative incidence function (CIF) was applied to analyze the association between different stages of CKD and revisions. Confounding factors such as diabetes and BMI were considered using either a stratified CIF or the Fine and Gray model.Aims
Methods
The reduction in mobility due to hip diseases in children is likely to affect their physical activity (PA) levels. Physical inactivity negatively influences quality of life and health. Our aim was to objectively measure PA in children with hip disease, and correlate it with the Patient-Reported Outcomes Measurement Information System (PROMIS) Mobility Score. A total of 28 children (12 boys and 16 girls) with hip disease aged between 8and 17 years (mean 12 (SD 3)) were studied between December 2018 and July 2019. Children completed the PROMIS Paediatric Item Bank v. 2.0 – Mobility Short Form 8a and wore a hip accelerometer (ActiGraph) for seven consecutive days. Sedentary time (ST), light PA (LPA), moderate to vigorous PA (MVPA), and vigorous PA were calculated from the accelerometers' data. The PROMIS Mobility score was classified as normal, mild, and moderate functions, based on the PROMIS cut scores on the physical function metric. A one-way analysis of covariance (ANCOVA) was used to assess differences among mobility (normal; mild; moderate) and measured PA and relationships between these variables were assessed using bivariate Pearson correlations.Aims
Methods
To investigate the experience and emotional impact of prosthetic joint infection (PJI) on orthopaedic surgeons and identify holistic strategies to improve the management of PJI and protect surgeons’ wellbeing. In total, 18 prosthetic joint surgeons in Sweden were recruited using a purposive sampling strategy. Content analysis was performed on transcripts of individual in-person interviews conducted between December 2017 and February 2018.Aims
Methods
The primary aim of this study was to evaluate the efficacy of distension arthrography in the treatment of adhesive capsulitis of the shoulder. The secondary aim was to assess which patient and procedural factors predicted the recurrence of symptoms after the procedure. All patients referred to our shoulder clinic over a ten-year period, between 2008 and 2018, with a clinical diagnosis of capsulitis and symptoms persisting for more than six months, were offered treatment with a distension arthrogram. All procedures were performed by one of five musculoskeletal radiologists, with a combination of steroid, local anaesthetic, and a distention volume of 10 ml, 30 ml, or 50 ml. Patient demographics, procedural details, recurrence of symptoms, and the need for further intervention were evaluated.Aims
Methods
The aim of this study was to develop a psychometrically sound measure of recovery for use in patients who have suffered an open tibial fracture. An initial pool of 109 items was generated from previous qualitative data relating to recovery following an open tibial fracture. These items were field tested in a cohort of patients recovering from an open tibial fracture. They were asked to comment on the content of the items and structure of the scale. Reduction in the number of items led to a refined scale tested in a larger cohort of patients. Principal components analysis permitted further reduction and the development of a definitive scale. Internal consistency, test-retest reliability, and responsiveness were assessed for the retained items.Aims
Methods
The aim of this study was to report our experience at 3.5 years with outpatient total hip arthroplasty (THA). In this prospective cohort study, we included all patients who were planned to receive primary THA through the anterior approach between 1 April 2014 and 1 October 2017. Patient-related data and surgical information were recorded. Patient reported outcome measures (PROMs) related to the hip and an anchor question were taken preoperatively, at six weeks, three months, and one year after surgery. All complications, readmissions, and reoperations were registered.Aims

Adductor canal block (ACB) has emerged as an alternative to femoral nerve block (FNB) for analgesia after total knee arthroplasty (TKA). The optimal duration of maintenance of the ACB is still questionable. The purpose of this study was to compare the analgesic benefits and physiotherapy (PT) outcomes of single-shot ACB to two different regimens of infusion of the continuous ACB, 24-hour and 48-hour infusion. This was a prospective, randomized, unblinded study. A total of 159 American Society of Anesthesiologists (ASA) physical status I to III patients scheduled for primary TKA were randomized to one of three study groups. Three patients did not complete the study, leaving 156 patients for final analysis. Group A (n = 53) was the single-shot group (16 female patients and 37 male patients with a mean age of 63.9 years (Aims
Patients and Methods
Despite declining frequency of blood transfusion and electrolyte supplementation following total joint arthroplasty, postoperative blood analyses are still routinely ordered for these patients. This study aimed to determine the rate of blood transfusion and electrolyte restoration in arthroplasty patients treated with a perioperative blood conservation protocol and to identify risk factors that would predict the need for transfusion and electrolyte supplementation. Patients undergoing primary total joint arthroplasty of the hip or knee between July 2016 and February 2017 at a single institution were included in the study. Standard preoperative and postoperative laboratory data were collected and reviewed retrospectively. A uniform blood conservation programme was implemented for all patients. Need for blood transfusion or potassium supplementation was determined through a coordinated decision by the care team. Rates of transfusion and supplementation were observed, and patient risk factors were noted.Aims
Patients and Methods
The glenohumeral joint is the most frequently dislocated articulation, but possibly due to the lower prevalence of posterior shoulder dislocations, approximately 50% to 79% of posterior glenohumeral dislocations are missed at initial presentation. The aim of this study was to systematically evaluate the most recent evidence involving the aetiology of posterior glenohumeral dislocations, as well as the diagnosis and treatment. A systematic search was conducted using PubMed (MEDLINE), Web of Science, Embase, and Cochrane (January 1997 to September 2017), with references from articles also evaluated. Studies reporting patients who experienced an acute posterior glenohumeral joint subluxation and/or dislocation, as well as the aetiology of posterior glenohumeral dislocations, were included.Aims
Materials and Methods
Rotator cuff tendinopathy has a multifactorial origin. Rejecting
the mechanistic theory has also led to abandoning operative treatment
at initial presentation in the first line. Physiotherapy exercise
programmes are the accepted first line treatment. The aim of this
study was to assess the long-term additional benefits of subacromial decompression
in the treatment of rotator cuff tendinopathy. This randomised controlled trial of 140 patients (52 men, 88
women, mean age 47.1 years; 18 to 60) with rotator cuff tendinopathy
extended previous work up to a maximum of 13 years. The patients
were randomised into two treatment groups: arthroscopic acromioplasty
and a supervised exercise treatment and a similar supervised exercise
treatment alone. Self-reported pain on a visual analogue scale (VAS)
was the primary outcome measure. Secondary measures were disability,
working ability, pain at night, Shoulder Disability Questionnaire
score and the number of painful days during the three months preceding
the final assessment.Aims
Patients and Methods
Outcome measures quantifying aspects of health in a precise,
efficient, and user-friendly manner are in demand. Computer adaptive
tests (CATs) may overcome the limitations of established fixed scales
and be more adept at measuring outcomes in trauma. The primary objective
of this review was to gain a comprehensive understanding of the
psychometric properties of CATs compared with fixed-length scales
in the assessment of outcome in patients who have suffered trauma
of the upper limb. Study designs, outcome measures and methodological
quality are defined, along with trends in investigation. A search of multiple electronic databases was undertaken on 1
January 2017 with terms related to “CATs”, “orthopaedics”, “trauma”,
and “anatomical regions”. Studies involving adults suffering trauma
to the upper limb, and undergoing any intervention, were eligible.
Those involving the measurement of outcome with any CATs were included.
Identification, screening, and eligibility were undertaken, followed
by the extraction of data and quality assessment using the Consensus-Based
Standards for the Selection of Health Measurement Instruments (COSMIN) criteria.
The review is reported according to the Preferred Reporting Items
for Systematic Reviews and Meta-Analyses (PRISMA) criteria and reg istered (PROSPERO: CRD42016053886).Aims

Clinical and radiological data were reviewed for all patients
with mucopolysaccharidoses (MPS) with thoracolumbar kyphosis managed
non-operatively or operatively in our institution. In all 16 patients were included (eight female: eight male; 50%
male), of whom nine had Hurler, five Morquio and two Hunter syndrome.
Six patients were treated non-operatively (mean age at presentation
of 6.3 years; 0.4 to 12.9); mean kyphotic progression +1.5o/year;
mean follow-up of 3.1 years (1 to 5.1) and ten patients operatively (mean

Amputation in intractable cases of complex regional pain syndrome
(CRPS) remains controversial. The likelihood of recurrent Complex Regional Pain Syndrome (CRPS),
residual and phantom limb pain and persistent disability after amputation
is poorly described in the literature. The aims of this study were
to compare pain, function, depression and quality of life between
patients with intractable CRPS who underwent amputation and those
in whom amputation was considered but not performed. There were 19 patients in each group, with comparable demographic
details. The amputated group included 14 men and five women with
a mean age of 31 years ( All participants completed the following questionnaires: Short-Form
(SF) 36, Short Form McGill Pain questionnaire (SF-MPQ), Pain Disability
Index (PDI), the Beck Depression Inventory (BDI) and a clinical
demographic questionnaire. Aims
Patients and Methods
The aims of this study were to compare the efficacy of two agents,
aspirin and warfarin, for the prevention of venous thromboembolism
(VTE) after simultaneous bilateral total knee arthroplasty (SBTKA),
and to elucidate the risk of VTE conferred by this procedure compared
with unilateral TKA (UTKA). A retrospective, multi-institutional study was conducted on 18
951 patients, 3685 who underwent SBTKA and 15 266 who underwent
UTKA, using aspirin or warfarin as VTE prophylaxis. Each patient
was assigned an individualised baseline VTE risk score based on
a system using the Nationwide Inpatient Sample. Symptomatic VTE,
including pulmonary embolism (PE) and deep vein thrombosis (DVT),
were identified in the first 90 days post-operatively. Statistical
analyses were performed with logistic regression accounting for
baseline VTE risk.Aims
Patients and Methods
Depression can significantly affect quality of life and is associated
with higher rates of medical comorbidities and increased mortality
following surgery. Although depression has been linked to poorer
outcomes following orthopaedic trauma, total joint arthroplasty
and spinal surgery, we wished to examine the impact of depression
in elective total shoulder arthroplasty (TSA) as this has not been
previously explored. The United States Nationwide Inpatient Sample (NIS) was used
to identify patients undergoing elective TSA over a ten-year period.
Between 2002 and 2012, 224 060 patients underwent elective TSA.Aims
Patients and Methods
The purpose of this study was to assess early physical function
after total hip or knee arthroplasty (THA/TKA), and the correlation
between patient-reported outcome measures, physical performance
and actual physical activity (measured by actigraphy). A total of 80 patients aged 55 to 80 years undergoing THA or
TKA for osteoarthritis were included in this prospective cohort
study. The main outcome measure was change in patient reported hip
or knee injury and osteoarthritis outcome score (HOOS/KOOS) from
pre-operatively until post-operative day 13 (THA) or 20 (TKA). Secondary measures
were correlations to objectively assessed change in physical performance
(paced-walk, chair-stand, stair-climb tests) at day 14 (THA) or
21 (TKA) and actual physical activity (actigraphy) measured at day
12 and 13 (THA) or 19 and 20 (TKA). Aims
Patients and Methods
The aims of this study were to report functional
outcomes of salvage procedures for patients with cerebral palsy (CP)
who have chronic dislocation of the hip using validated scoring
systems, and to compare the results of three surgical techniques. We reviewed 37 patients retrospectively. The mean age at the
time of surgery was 12.2 years (8 to 22) and the mean follow-up
was 56 months (24 to 114). Patients were divided into three groups:
14 who underwent proximal femoral resection arthroplasty (PFRA group
1), ten who underwent subtrochanteric valgus osteotomy (SVO group 2),
and 13 who underwent subtrochanteric valgus osteotomy with resection
of the femoral head (SVO with FHR group 3). All patients were evaluated
using the Caregiver Priorities and Child Health Index of Life with
Disabilities (CPCHILD) and the Pediatric Quality of Life Inventory
(PedsQL). Significant improvements occurred in most CPCHILD and PedsQL
subsection scores following surgery in all patients, without significant
differences between the groups. There were 12 post-operative complications.
Less severe complications were seen in group 1 than in groups 2
and 3. Salvage surgery appears to provide pain relief in patients with
CP who have painful chronic dislocation of the hip. The three salvage
procedures produced similar results, however, we recommend the use
of PFRA as the complications are less severe. Take home message: Salvage surgery can be of benefit to patients
with CP with chronic painful hip dislocation, but should be limited
to selected patients considering complications. Cite this article:
Acute angulation at the thoracolumbar junction
with segmental subluxation of the spine occurring at the level above
an anteriorly hypoplastic vertebra in otherwise normal children
is a rare condition described as infantile developmental thoracolumbar
kyphosis. Three patient series with total of 18 children have been
reported in the literature. We report five children who presented
with thoracolumbar kyphosis and discuss the treatment algorithm. We
reviewed the medical records and spinal imaging at initial clinical
presentation and at minimum two-year follow-up. The mean age at
presentation was eight months (two to 12). All five children had
L2 anterior vertebral body hypoplasia. The kyphosis improved spontaneously
in three children kept under monitoring. In contrast, the deformity
was progressive in two patients who were treated with bracing. The
kyphosis and segmental subluxation corrected at latest follow-up
(mean age 52 months; 48 to 60) in all patients with near complete
reconstitution of the anomalous vertebra. The deformity and radiological
imaging on a young child can cause anxiety to both parents and treating
physicians. Diagnostic workup and treatment algorithm in the management
of infantile developmental thoracolumbar kyphosis is proposed. Observation
is indicated for non-progressive kyphosis and bracing if there is evidence

We compared the outcome of total hip arthroplasty (THA) in obese
patients who previously underwent bariatric surgery and those who
did not, in a matched cohort study. There were 47 THAs in the bariatric group (42 patients), and
94 THAs in the comparison group (92 patients). The mean age of the
patients was 57 years in both groups (24 to 79) and 57% of the patients
in both groups were women. The mean time between bariatric surgery
and THA was five years (four months to 12 years) in the bariatric group.
The mean follow-up after THA was three years (2 to 9). Aims
Patients and Methods
We describe our experience in the reduction of
dislocation of the hip secondary to developmental dysplasia using ultrasound-guided
gradual reduction using flexion and abduction continuous traction
(FACT-R). During a period of 13 years we treated 208 Suzuki type
B or C complete dislocations of the hip in 202 children with a mean
age of four months (0 to 11). The mean follow-up was 9.1 years (five
to 16). The rate of reduction was 99.0%. There were no recurrent
dislocations, and the rate of avascular necrosis of the femoral
head was 1.0%. The rate of secondary surgery for residual acetabular
dysplasia was 19.2%, and this was significantly higher in those
children in whom the initial treatment was delayed or if other previous
treatments had failed (p = 0.00045). The duration of FACT-R was significantly
longer in severe dislocations (p = 0.001) or if previous treatments
had failed (p = 0.018). This new method of treatment is effective and safe in these difficult
cases and offers outcomes comparable to or better than those of
standard methods. Cite this article:
The outcome after total hip replacement has improved
with the development of surgical techniques, better pain management
and the introduction of enhanced recovery pathways. These pathways
require a multidisciplinary team to manage pre-operative education,
multimodal pain control and accelerated rehabilitation. The current economic
climate and restricted budgets favour brief hospitalisation while
minimising costs. This has put considerable pressure on hospitals
to combine excellent results, early functional recovery and shorter
admissions. In this review we present an evidence-based summary of some common
interventions and methods, including pre-operative patient education,
pre-emptive analgesia, local infiltration analgesia, pre-operative
nutrition, the use of pulsed electromagnetic fields, peri-operative
rehabilitation, wound dressings, different surgical techniques, minimally
invasive surgery and fast-track joint replacement units. Cite this article:
In order to prevent dislocation of the hip after total hip arthroplasty
(THA), patients have to adhere to precautions in the early post-operative
period. The hypothesis of this study was that a protocol with minimal
precautions after primary THA using the posterolateral approach
would not increase the short-term (less than three months) risk
of dislocation. We prospectively monitored a group of unselected patients undergoing
primary THA managed with standard precautions (n = 109, median age
68.9 years; interquartile range (IQR) 61.2 to 77.3) and a group
who were managed with fewer precautions (n = 108, median age 67.2
years; IQR 59.8 to 73.2). There were no significant differences between
the groups in relation to predisposing risk factors. The diameter
of the femoral head ranged from 28 mm to 36 mm; meticulous soft-tissue
repair was undertaken in all patients. The medical records were
reviewed and all patients were contacted three months post-operatively
to confirm whether they had experienced a dislocation. Aims
