Periprosthetic joint infection represents a devastating complication after total elbow arthroplasty. Several measures can be implemented before, during, and after surgery to decrease infection rates, which exceed 5%. Debridement with antibiotics and implant retention has been reported to be successful in less than one-third of acute infections, but still plays a role. For elbows with well-fixed implants, staged retention seems to be equally successful as the more commonly performed two-stage reimplantation, both with a success rate of 70% to 80%. Permanent resection or even amputation are occasionally considered. Not uncommonly, a second-stage reimplantation requires complex reconstruction of the skeleton with allografts, and the extensor mechanism may also be deficient. Further developments are needed to improve our management of infection after elbow arthroplasty. Cite this article:
The aim of this study is to evaluate the change in incidence rate of shoulder arthroplasty, indications, and surgeon volume trends associated with these procedures between January 2003 and April 2021 in the province of Nova Scotia, Canada. A total of 1,545 patients between 2005 and 2021 were analyzed. Patients operated on between 2003 and 2004 were excluded due to a lack of electronic records. Overall, 84.1% of the surgeries (n = 1,299) were performed by two fellowship-trained upper limb surgeons, with the remainder performed by one of the 14 orthopaedic surgeons working in the province.Aims
Methods
The aim of this study was to analyze how proximal radial neck resorption (PRNR) starts and progresses radiologically in two types of press-fit radial head arthroplasties (RHAs), and to investigate its clinical relevance. A total of 97 patients with RHA were analyzed: 56 received a bipolar RHA (Group 1) while 41 received an anatomical implant (Group 2). Radiographs were performed postoperatively and after three, six, nine, and 12 weeks, six, nine, 12, 18, and 24 months, and annually thereafter. PRNR was measured in all radiographs in the four radial neck quadrants. The Mayo Elbow Performance Score (MEPS), the abbreviated version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), and the patient-assessed American Shoulder and Elbow Surgeons score - Elbow (pASES-E) were used for the clinical assessment. Radiological signs of implant loosening were investigated.Aims

The aim of this study was to review the provision of total elbow arthroplasties (TEAs) in England, including the incidence, the characteristics of the patients and the service providers, the types of implant, and the outcomes. We analyzed the primary TEAs recorded in the National Joint Registry (NJR) between April 2012 and December 2022, with mortality data from the Civil Registration of Deaths dataset. Linkage with Hospital Episode Statistics-Admitted Patient Care (HES-APC) data provided further information not collected by the NJR. The incidences were calculated using estimations of the populations from the Office for National Statistics. The annual number of TEAs performed by surgeons and hospitals was analyzed on a national and regional basis.Aims

There are concerns regarding complications and longevity of total elbow arthroplasty (TEA) in young patients, and the few previous publications are mainly limited to reports on linked elbow devices. We investigated the clinical outcome of unlinked TEA for patients aged less than 50 years with rheumatoid arthritis (RA). We retrospectively reviewed the records of 26 elbows of 21 patients with RA who were aged less than 50 years who underwent primary TEA with an unlinked elbow prosthesis. The mean patient age was 46 years (35 to 49), and the mean follow-up period was 13.6 years (6 to 27). Outcome measures included pain, range of motion, Mayo Elbow Performance Score (MEPS), radiological evaluation for radiolucent line and loosening, complications, and revision surgery with or without implant removal.Aims

We sought to compare functional outcomes and survival between non-smokers, former smokers, and current smokers who underwent anatomical total shoulder arthroplasty (aTSA) in a large cohort of patients. A retrospective review of a prospectively collected shoulder arthroplasty database was performed between August 1991 and September 2020 to identify patients who underwent primary aTSA. Patients were excluded for preoperative diagnoses of fracture, infection, or oncological disease. Three cohorts were created based on smoking status: non-smokers, former smokers, and current smokers. Outcome scores (American Shoulder and Elbow Surgeons (ASES), Constant-Murley score, Shoulder Pain and Disability Index (SPADI), Simple Shoulder Test (SST), University of California, Los Angeles activity scale (UCLA)), range of motion (external rotation (ER), forward elevation (FE), internal rotation, abduction), and shoulder strength (ER, FE) evaluated at two- to four-year follow-up were compared between cohorts. Evaluation of revision-free survival was performed using the Kaplan-Meier method to final follow-up.Aims

Reverse total shoulder arthroplasty (rTSA) can be used in complex cases when the glenoid requires reconstruction. In this study, a baseplate with composite bone autograft and a central trabecular titanium peg was implanted, and its migration was assessed for two years postoperatively using radiostereometric analysis (RSA). A total of 14 patients who underwent a rTSA with an autograft consented to participate. Of these, 11 had a primary rTSA using humeral head autograft and three had a revision rTSA with autograft harvested from the iliac crest. The mean age of the patients was 66 years (39 to 81). Tantalum beads were implanted in the scapula around the glenoid. RSA imaging (stereographic radiographs) was undertaken immediately postoperatively and at three, six, 12, and 24 months. Analysis was completed using model-based RSA software. Outcomes were collected preoperatively and at two years postoperatively, including the Oxford Shoulder Score, the American Shoulder and Elbow Score, and a visual analogue score for pain. A Constant score was also obtained for the assessment of strength and range of motion.Aims

The prevalence of osteoarthritis (OA) associated with instability of the shoulder ranges between 4% and 60%. Articular cartilage is, however, routinely assessed in these patients using radiographs or scans (2D or 3D), with little opportunity to record early signs of cartilage damage. The aim of this study was to assess the prevalence and localization of chondral lesions and synovial damage in patients undergoing arthroscopic surgery for instablility of the shoulder, in order to classify them and to identify risk factors for the development of glenohumeral OA. A total of 140 shoulders in 140 patients with a mean age of 28.5 years (15 to 55), who underwent arthroscopic treatment for recurrent glenohumeral instability, were included. The prevalence and distribution of chondral lesions and synovial damage were analyzed and graded into stages according to the division of the humeral head and glenoid into quadrants. The following factors that might affect the prevalence and severity of chondral damage were recorded: sex, dominance, age, age at the time of the first dislocation, number of dislocations, time between the first dislocation and surgery, preoperative sporting activity, Beighton score, type of instability, and joint laxity.Aims
Methods
Shoulder arthroplasty is effective in the management of end-stage glenohumeral joint arthritis. However, it is major surgery and patients must balance multiple factors when considering the procedure. An understanding of patients’ decision-making processes may facilitate greater support of those considering shoulder arthroplasty and inform the outcomes of future research. Participants were recruited from waiting lists of three consultant upper limb surgeons across two NHS hospitals. Semi-structured interviews were conducted with 12 participants who were awaiting elective shoulder arthroplasty. Transcribed interviews were analyzed using a grounded theory approach. Systematic coding was performed; initial codes were categorized and further developed into summary narratives through a process of discussion and refinement. Data collection and analyses continued until thematic saturation was reached.Aims

Reverse shoulder arthroplasty (RSA) has become the most common type of shoulder arthroplasty used in the UK, and a better understanding of the outcomes after revision of a failed RSA is needed. The aim of this study was to review the current evidence systematically to determine patient-reported outcome measures and the rates of re-revision and complications for patients undergoing revision of a RSA. MEDLINE, Embase, CENTRAL, and the Cochrane Database of Systematic Reviews were searched. Studies involving adult patients who underwent revision of a primary RSA for any indication were included. Those who underwent a RSA for failure of a total shoulder arthroplasty or hemiarthroplasty were excluded. Pre- and postoperative shoulder scores were evaluated in a random effects meta-analysis to determine the mean difference. The rates of re-revision and complications were also calculated.Aims

The Oxford Shoulder Score (OSS) is a 12-item measure commonly used for the assessment of shoulder surgeries. This study explores whether computerized adaptive testing (CAT) provides a shortened, individually tailored questionnaire while maintaining test accuracy. A total of 16,238 preoperative OSS were available in the National Joint Registry (NJR) for England, Wales, Northern Ireland, the Isle of Man, and the States of Guernsey dataset (April 2012 to April 2022). Prior to CAT, the foundational item response theory (IRT) assumptions of unidimensionality, monotonicity, and local independence were established. CAT compared sequential item selection with stopping criteria set at standard error (SE) < 0.32 and SE < 0.45 (equivalent to reliability coefficients of 0.90 and 0.80) to full-length patient-reported outcome measure (PROM) precision.Aims

The aim of this study was to characterize the influence of social deprivation on the rate of complications, readmissions, and revisions following primary total shoulder arthroplasty (TSA), using the Social Deprivation Index (SDI). The SDI is a composite measurement, in percentages, of seven demographic characteristics: living in poverty, with < 12 years of education, single-parent households, living in rented or overcrowded housing, households without a car, and unemployed adults aged < 65 years. Patients aged ≥ 40 years, who underwent primary TSA between 2011 and 2017, were identified using International Classification of Diseases (ICD)-9 Clinical Modification and ICD-10 procedure codes for TSA in the New York Statewide Planning and Research Cooperative System database. Readmission, reoperation, and other complications were analyzed using multivariable Cox proportional hazards regression controlling for SDI, age, ethnicity, insurance status, and Charlson Comorbidity Index.Aims

The survival of humeral hemiarthroplasties in patients with relatively intact glenoid cartilage could theoretically be extended by minimizing the associated postoperative glenoid erosion. Ceramic has gained attention as an alternative to metal as a material for hemiarthroplasties because of its superior tribological properties. The aim of this study was to assess the in vitro wear performance of ceramic and metal humeral hemiarthroplasties on natural glenoids. Intact right cadaveric shoulders from donors aged between 50 and 65 years were assigned to a ceramic group (n = 8, four male cadavers) and a metal group (n = 9, four male cadavers). A dedicated shoulder wear simulator was used to simulate daily activity by replicating the relevant joint motion and loading profiles. During testing, the joint was kept lubricated with diluted calf serum at room temperature. Each test of wear was performed for 500,000 cycles at 1.2 Hz. At intervals of 125,000 cycles, micro-CT scans of each glenoid were taken to characterize and quantify glenoid wear by calculating the change in the thickness of its articular cartilage.Aims
Methods
Metal and ceramic humeral head bearing surfaces are available choices in anatomical shoulder arthroplasties. Wear studies have shown superior performance of ceramic heads, however comparison of clinical outcomes according to bearing surface in total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) is limited. This study aimed to compare the rates of revision and reoperation following metal and ceramic humeral head TSA and HA using data from the National Joint Registry (NJR), which collects data from England, Wales, Northern Ireland, Isle of Man and the States of Guernsey. NJR shoulder arthroplasty records were linked to Hospital Episode Statistics and the National Mortality Register. TSA and HA performed for osteoarthritis (OA) in patients with an intact rotator cuff were included. Metal and ceramic humeral head prostheses were matched within separate TSA and HA groups using propensity scores based on 12 and 11 characteristics, respectively. The primary outcome was time to first revision and the secondary outcome was non-revision reoperation.Aims
Methods
Both anatomical and reverse total shoulder arthroplasty (aTSA and rTSA) provide functional improvements. A reported benefit of aTSA is better range of motion (ROM). However, it is not clear which procedure provides better outcomes in patients with limited foward elevation (FE). The aim of this study was to compare the outcome of aTSA and rTSA in patients with glenohumeral osteoarthritis (OA), an intact rotator cuff, and limited FE. This was a retrospective review of a single institution’s prospectively collected shoulder arthroplasty database for TSAs undertaken between 2007 and 2020. A total of 344 aTSAs and 163 rTSAs, which were performed in patients with OA and an intact rotator cuff with a minimum follow-up of two years, were included. Using the definition of preoperative stiffness as passive FE ≤ 105°, three cohorts were matched 1:1 by age, sex, and follow-up: stiff aTSAs (85) to non-stiff aTSAs (85); stiff rTSAs (74) to non-stiff rTSAs (74); and stiff rTSAs (64) to stiff aTSAs (64). We the compared ROMs, outcome scores, and complication and revision rates.Aims

The conventionally described mechanism of distal biceps tendon rupture (DBTR) is of a ‘considerable extension force suddenly applied to a resisting, actively flexed forearm’. This has been commonly paraphrased as an ‘eccentric contracture to a flexed elbow’. Both definitions have been frequently used in the literature with little objective analysis or citation. The aim of the present study was to use video footage of real time distal biceps ruptures to revisit and objectively define the mechanism of injury. An online search identified 61 videos reporting a DBTR. Videos were independently reviewed by three surgeons to assess forearm rotation, elbow flexion, shoulder position, and type of muscle contraction being exerted at the time of rupture. Prospective data on mechanism of injury and arm position was also collected concurrently for 22 consecutive patients diagnosed with an acute DBTR in order to corroborate the video analysis.Aims

Corticosteroid injections are often used to manage glenohumeral arthritis in patients who may be candidates for future total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (rTSA). In the conservative management of these patients, corticosteroid injections are often provided for symptomatic relief. The purpose of this study was to determine if the timing of corticosteroid injections prior to TSA or rTSA is associated with changes in rates of revision and periprosthetic joint infection (PJI) following these procedures. Data were collected from a national insurance database from January 2006 to December 2017. Patients who underwent shoulder corticosteroid injection within one year prior to ipsilateral TSA or rTSA were identified and stratified into the following cohorts: < three months, three to six months, six to nine months, and nine to 12 months from time of corticosteroid injection to TSA or rTSA. A control cohort with no corticosteroid injection within one year prior to TSA or rTSA was used for comparison. Univariate and multivariate analyses were conducted to determine the association between specific time intervals and outcomes.Aims

Stemless humeral implants have been developed to overcome stem-related complications in total shoulder arthroplasty (TSA). However, stemless implant designs may hypothetically result in less stable initial fixation, potentially affecting long-term survival. The aim of this study is to investigate early fixation and migration patterns of the stemless humeral component of the Simpliciti Shoulder System and to evaluate clinical outcomes. In this prospective cohort study, radiostereometric analysis (RSA) radiographs were obtained in 24 patients at one day, six weeks, six months, one year, and two years postoperatively. Migration was calculated using model-based RSA. Clinical outcomes were evaluated using the visual analogue scale (VAS), the Oxford Shoulder Score (OSS), the Constant-Murley Score (CMS), and the Disabilities of the Arm, Shoulder and Hand (DASH) score.Aims
Methods
The main objective of this study was to examine whether the Oxford Shoulder Score (OSS) demonstrated floor or ceiling effects when used to measure outcomes following shoulder arthroplasty in a large national cohort. Secondary objectives were to assess its pain and function subscales, and to identify independent predictors for patients achieving a postoperative ceiling score following shoulder arthroplasty. Secondary database analysis of the National Joint Registry (NJR), which included 48,270 patients undergoing shoulder arthroplasty, was conducted. The primary outcome measure was the OSS. Secondary outcome measures were the OSS-Function Component Subscale and OSS-Pain Component Subscale. Floor and ceiling effects were considered to be present if > 15% of patients scored either the lowest or highest possible score. Logistic regression analysis was used to identify independent predictors for scoring the highest possible OSS score postoperatively.Aims

Reverse total shoulder arthroplasty (RTSA) using trabecular metal (TM)-backed glenoid implants has been introduced with the aim to increase implant survival. Only short-term reports on the outcomes of TM-RTSA have been published to date. We aim to present the seven-year survival of TM-backed glenoid implants along with minimum five-year clinical and radiological outcomes. All consecutive elective RTSAs performed at a single centre between November 2008 and October 2014 were reviewed. Patients who had primary TM-RTSA for rotator cuff arthropathy and osteoarthritis with deficient cuff were included. A total of 190 shoulders in 168 patients (41 male, 127 female) were identified for inclusion at a mean of 7.27 years (SD 1.4) from surgery. The primary outcome was survival of the implant with all-cause revision and aseptic glenoid loosening as endpoints. Secondary outcomes were clinical, radiological, and patient-related outcomes with a five-year minimum follow-up.Aims

To investigate the impact of the Charlson and Elixhauser comorbidity indices on patient-reported outcomes measures (PROMs) following shoulder arthroplasty. Patients undergoing total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), or hemiarthroplasty (HA) from 2016 to 2018 were identified, along with the Charlson and Elixhauser comorbidities listed as their secondary diagnoses in the electronic medical records. Patients were matched to our institution’s registry to obtain their PROMs, including shoulder-specific (American Shoulder and Elbow Society (ASES) and Shoulder Activity Scale (SAS)) and general health scales (12-Item Short Form Survey (SF-12) and Patient-Reported Outcomes Measurement Information System-Pain Interference). Linear regression models adjusting for age and sex were used to evaluate the association between increasing number of comorbidities and PROM scores. A total of 1,817 shoulder arthroplasties were performed: 1,017 (56%) TSA, 726 (40%) RSA, and 74 (4%) HA. The mean age was 67 years (SD 10), and 936 (52%) of the patients were female.Aims

Objectives. The goal of this study is to investigate the relation between indicators of osteoporosis (i.e., bone mineral density (BMD), and Cortical Index (CI)) and the complexity of a fracture of the proximal humerus as a result of a low-energy trauma. Methods. A retrospective chart review of 168 patients (mean age 67.2 years, range 51 to 88.7) with a fracture of the proximal humerus between 2007 and 2011, whose BMD was assessed at the Fracture Liaison Service with Dual Energy X-ray Absorptiometry (DXA) measurements of the
It has been hypothesized that proximal radial neck resorption (PRNR) following press-fit radial head arthroplasty (RHA) is due to stress-shielding. We compared two different press-fit stems by means of radiographs to investigate whether the shape and size of the stems are correlated with the degree of PRNR. The radiographs of 52 RHAs were analyzed both at 14 days postoperatively and after two years. A cylindrical stem and a conical stem were implanted in 22 patients (group 1) and 30 patients (group 2), respectively. The PRNR was measured in the four quadrants of the radial neck and the degree of stem filling was calculated by analyzing the ratio between the prosthetic stem diameter (PSD) and the medullary canal diameter (MCD) at the proximal portion of the stem (level A), halfway along the stem length (level B), and distally at the stem tip (level C).Aims

The purpose of this study was to evaluate the cost of reverse shoulder arthroplasty (RSA) for patients with a proximal humerus fracture, using time-driven activity based costing (TDABC), and to compare treatment costs with reimbursement under the Healthcare Resource Groups (HRGs). TDABC analysis based on the principles outlined by Kaplan and a clinical pathway that has previously been validated for this institution was used. Staffing cost, consumables, implants, and overheads were updated to reflect 2019/2020 costs. This was compared with the HRG reimbursements.Aims

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

Heterotopic ossification (HO) is a potentially devastating complication of the surgical treatment of a proximal humeral fracture. The literature on the rate and risk factors for the development of HO under these circumstances is lacking. The aim of this study was to determine the incidence and risk factors for the development of HO in these patients. A retrospective analysis of 170 patients who underwent operative treatment for a proximal humeral fracture between 2005 and 2016, in a single institution, was undertaken. The mean follow-up was 18.2 months (1.5 to 140). The presence of HO was identified on follow-up radiographs.Aims

Patient-specific instrumentation has been shown to increase a surgeon’s precision and accuracy in placing the glenoid component in shoulder arthroplasty. There is, however, little available information about the use of patient-specific planning (PSP) tools for this operation. It is not known how these tools alter the decision-making patterns of shoulder surgeons. The aim of this study was to investigate whether PSP, when compared with the use of plain radiographs or select static CT images, influences the understanding of glenoid pathology and surgical planning. A case-based survey presented surgeons with a patient’s history, physical examination, and, sequentially, radiographs, select static CT images, and PSP with a 3D imaging program. For each imaging modality, the surgeons were asked to identify the Walch classification of the glenoid and to propose the surgical treatment. The participating surgeons were grouped according to the annual volume of shoulder arthroplasties that they undertook, and responses were compared with the recommendations of two experts.Aims

To compare complication-related reoperation rates following primary arthroplasty for proximal humerus fractures (PHFs) We identified patients aged 50 years and over, who sustained a PHF between 2004 and 2015, from linkable datasets. We used intervention codes to identify patients treated with initial ORIF or arthroplasty, and those treated with ORIF who returned for revision arthroplasty within two years. We used multilevel logistic regression to compare reoperations between groups.Aims

The purpose of the present study was to evaluate the impact of
intravenous tranexamic acid on the reduction of blood loss, transfusion
rate, and early post-operative clinical outcome in total shoulder
arthroplasty. A randomised, placebo-controlled trial which included 54 patients
undergoing unilateral primary stemless anatomical or stemmed reverse
total shoulder arthroplasty was undertaken. Patients received either
100 ml saline (placebo, n = 27), or 100 ml saline together with
1000 mg of tranexamic acid (TXA, n = 27) intravenously prior to
skin incision and during wound closure. Peri-operative blood loss
via an intra-articular drain was recorded and total blood loss was
calculated. The post-operative transfusion rate was documented.
Assessment of early clinical parameters included the visual analogue

Few studies have evaluated the relationship between patients’
pre-operative expectations and the outcome of orthopaedic procedures.
Our aim was to determine the effect of expectations on the outcome
after primary anatomical total shoulder arthroplasty (TSA). We hypothesised
that patients with greater expectations would have better outcomes. Patients undergoing primary anatomical TSA completed the Hospital
for Special Surgery’s Shoulder Expectations Survey pre-operatively.
The American Shoulder and Elbow Surgeons (ASES), Shoulder Activity
Scale (SAS), Short-Form-36 (SF-36), and visual analogue scale (VAS)
for pain, fatigue, and general health scores were also collected
pre-operatively and two years post-operatively. Pearson correlations
were used to assess the relationship between the number of expectations
and the outcomes. Differences in outcomes between those with higher
and lower levels of expectations for each expectation were assessed
by independent samples Aims

In the initial development of total shoulder arthroplasty (TSA),
the humeral component was usually fixed with cement. Cementless
components were subsequently introduced. The aim of this study was
to compare the long-term outcome of cemented and cementless humeral
components in arthroplasty of the shoulder. All patients who underwent primary arthroplasty of the shoulder
at our institution between 1970 and 2012 were included in the study.
There were 4636 patients with 1167 cemented humeral components and
3469 cementless components. Patients with the two types of fixation
were matched for nine different covariates using a propensity score
analysis. A total of 551 well-balanced pairs of patients with cemented
and cementless components were available after matching for comparison
of the outcomes. The clinical outcomes which were analysed included loosening
of the humeral component determined at revision surgery, periprosthetic
fractures, post-operative infection and operating time.Aims

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

Revision total elbow arthroplasty (TEA) is often challenging.
The aim of this study was to report on the clinical and radiological
results of revision arthroplasty of the elbow with the Latitude
TEA. Between 2006 and 2010 we used the Latitude TEA for revision in
18 consecutive elbows (17 patients); mean age 53 years (28 to 80);
14 women. A Kudo TEA was revised in 15 elbows and a Souter-Strathclyde
TEA in three. Stability, range of movement (ROM), visual analogue score (VAS)
for pain and functional scores, Elbow Functional Assessment Scale
(EFAS), the Functional Rating Index of Broberg and Morrey (FRIBM)
and the Modified Andrews’ Elbow Scoring System (MAESS) were assessed
pre-operatively and at each post-operative follow-up visit (six,

The ageing population and an increase in both
the incidence and prevalence of cancer pose a healthcare challenge, some
of which is borne by the orthopaedic community in the form of osteoporotic
fractures and metastatic bone disease. In recent years there has
been an increasing understanding of the pathways involved in bone
metabolism relevant to osteoporosis and metastases in bone. Newer
therapies may aid the management of these problems. One group of
drugs, the antibody mediated anti-resorptive therapies (AMARTs)
use antibodies to block bone resorption pathways. This review seeks
to present a synopsis of the guidelines, pharmacology and potential pathophysiology
of AMARTs and other new anti-resorptive drugs. We evaluate the literature relating to AMARTs and new anti-resorptives
with special attention on those approved for use in clinical practice. Denosumab, a monoclonal antibody against Receptor Activator for
Nuclear Factor Kappa-B Ligand. It is the first AMART approved by
the National Institute for Health and Clinical Excellence and the
US Food and Drug Administration. Other novel anti-resorptives awaiting
approval for clinical use include Odanacatib. Denosumab is indicated for the treatment of osteoporosis and
prevention of the complications of bone metastases. Recent evidence
suggests, however, that denosumab may have an adverse event profile
similar to bisphosphonates, including atypical femoral fractures.
It is, therefore, essential that orthopaedic surgeons are conversant
with these medications and their safe usage. Take home message: Denosumab has important orthopaedic indications
and has been shown to significantly reduce patient morbidity in
osteoporosis and metastatic bone disease. Cite this article:
We describe the use of a protocol of irrigation and debridement
(I&
D) with retention of the implant for the treatment of periprosthetic
infection of a total elbow arthroplasty (TEA). This may be an attractive
alternative to staged re-implantation. Between 1990 and 2010, 23 consecutive patients were treated in
this way. Three were lost to follow-up leaving 20 patients (21 TEAs)
in the study. There were six men and 14 women. Their mean age was
58 years (23 to 76). The protocol involved: component unlinking,
irrigation and debridement (I&
D), and the introduction of antibiotic
laden cement beads; organism-specific intravenous antibiotics; repeat
I&
D and re-linkage of the implant if appropriate; long-term
oral antibiotic therapy. Aims
Patients and Methods
We present the medium-term clinical results of a reverse total
shoulder arthroplasty with a trabecular metal glenoid base plate. We reviewed 125 consecutive primary reverse total shoulder arthroplasties
(RTSA) implanted in 124 patients for rotator cuff arthropathy. There
were 100 women and 24 men in the study group with a mean age of
76 years (58 to 89). The mean follow-up was 32 months (24 to 60).
No patient was lost to follow-up.Aim
Patients and Methods
Currently, there is little information about the need for peri-operative
blood transfusion in patients undergoing shoulder arthroplasty. The purpose of this study was to identify the rate of transfusion
and its predisposing factors, and to establish a blood conservation
strategy. We identified all patients who had undergone shoulder arthroplasty
at our hospital between 1 January 2011 and 31 December 2013. The
rate of transfusion was determined from the patient’s records. While
there were exceptions, patients typically underwent transfusion
if they had a level of haemoglobin of <
7.5 g/dl if asymptomatic,
<
9.0 g/dl if they had a significant cardiac history or symptoms
of dizziness or light headedness. Multivariable regression analysis was undertaken to identify
predictors of transfusion. High- and low-risk cohorts for transfusion
were identified from a receiver operating characteristic (ROC) curve.Aims
Methods
To assess the extent of osteointegration in two designs of shoulder
resurfacing implants. Bony integration to the Copeland cylindrical
central stem design and the Epoca RH conical-crown design were compared. Implants retrieved from six patients in each group were pair-matched.
Mean time to revision surgery of Copeland implants was 37 months

Patients and Methods
We report our experience of performing an elbow
hemiarthroplasty in the treatment of comminuted distal humeral fractures
in the elderly patients. A cohort of 42 patients (three men and 39 women, mean age 72;
56 to 84) were reviewed at a mean of 34.3 months (24 to 61) after
surgery. Functional outcome was measured with the Mayo Elbow Performance
Score (MEPS) and range of movement. The disabilities of the arm,
shoulder and hand questionnaire (DASH) was used as a patient rated
evaluation. Complications and ulnar nerve function were recorded.
Plain radiographs were obtained to assess prosthetic loosening,
olecranon wear and heterotopic bone formation. The mean extension deficit was 23.5° (0° to 60°) and mean flexion
was 126.8° (90° to 145°) giving a mean arc of 105.5° (60° to 145°).
The mean MEPS was 90 (50 to 100) and a mean DASH score of 20 (0
to 63). Four patients had additional surgery for limited range of
movement and one for partial instability. One elbow was revised
due to loosening, two patients had sensory ulnar nerve symptoms,
and radiographic signs of mild olecranon wear was noted in five
patients. Elbow hemiarthroplasty for comminuted intra-articular distal
humeral fractures produces reliable medium-term results with functional
outcome and complication rates, comparable with open reduction and
internal fixation and total elbow arthroplasty. Cite this article:
Unlinked, linked and convertible total elbow
arthroplasties (TEAs) are currently available. This study is the
first to report the clinical results of the convertible Latitude
TEA. This was a retrospective study of a consecutive cohort of 63
patients (69 primary TEAs) with a mean age of 60 years (23 to 87).
Between 2006 and 2008 a total of 19 men and 50 women underwent surgery.
The mean follow-up was 43 months (8 to 84). The range of movement,
function and pain all improved six months post-operatively and either
continued to improve slightly or reached a plateau thereafter. The
complication rate is similar to that reported for other TEA systems.
No loosening was seen. Remarkable is the disengagement of the radial
head component in 13 TEAs (31%) with a radial head component implanted. Implantation of both the linked and the unlinked versions of
the Latitude TEA results in improvement of function and decreased
pain, and shows high patient satisfaction at mid-term follow-up. Cite this article:
Treatment of an infected total elbow replacement
(TER) is often successful in eradicating or suppressing the infection.
However, the extensor mechanism may be compromised by both the infection
and the surgery. The goal of this study was to assess triceps function
in patients treated for deep infection complicating a TER. Between
1976 and 2007 a total of 217 TERs in 207 patients were treated for
infection of a TER at our institution. Superficial infections and
those that underwent resection arthroplasty were excluded, leaving
93 TERs. Triceps function was assessed by examination and a questionnaire.
Outcome was measured using the Mayo Elbow Performance Score (MEPS). Triceps weakness was identified in 51 TERs (49 patients, 55%).
At a mean follow-up of five years (0.8 to 34), the extensor mechanism
was intact in 13 patients, with the remaining 38 having bone or
soft-tissue loss. The mean MEPS was 70 points (5 to 100), with a
mean functional score of 18 (0 to 25) of a possible 25 points. Infection following TER can often be eradicated; however, triceps
weakness occurs in more than half of the patients and may represent
a major functional problem. Cite this article:
We report our experience of staged revision surgery
for the treatment of infected total elbow arthroplasty (TEA). Between
1998 and 2010 a consecutive series of 33 patients (34 TEAs) underwent
a first-stage procedure with the intention to proceed to second-stage
procedure when the infection had been controlled. A single first-stage procedure
with removal of the components and cement was undertaken for 29
TEAs (85%), followed by the insertion of antibiotic-impregnated
cement beads, and five (15%) required two or more first-stage procedures.
The most common organism isolated was coagulase-negative A second-stage procedure was performed for 26 TEAs (76%); seven
patients (seven TEAs, 21%) had a functional resection arthroplasty
with antibiotic beads There were three recurrent infections (11.5%) in those patients
who underwent a second-stage procedure. The infection presented
at a mean of eight months (5 to 10) post-operatively. The mean Mayo
Elbow Performance Score (MEPS) in those who underwent a second stage
revision without recurrent infection was 81.1 (65 to 95). Staged revision surgery is successful in the treatment of patients
with an infected TEA and is associated with a low rate of recurrent
infection. However, when infection does occur, this study would
suggest that it becomes apparent within ten months of the second
stage procedure. Cite this article:
