Anatomic Reversal of Shoulder Joint After Neck of Humerus Fracture.

We report on a singular case of a unique form of post-traumatic reversal of the humeral head after humeral neck fracture, in which the pattern of collapse resulted in the formation of a native reverse polarity shoulder. In essence, the humeral head became a socket, and the glenoid rounded to become a head with well-preserved shoulder function. To our knowledge, this is the first case of an acquired shoulder deformity that bears a remarkable functional similarity to a prosthetic reverse polarity shoulder replacement.

A systematic review of the treatment of distal humerus fractures in older adults: A comparison of surgical and non-surgical options.

Background: Fractures of the distal humerus are a common fragility fracture in older adults. The purpose of this study was to systematically review the literature to produce pooled estimates of the outcomes of treatment using total elbow arthroplasty (TEA), open reduction and locking plate fixation (ORIF), hemiarthroplasty or with conservative management. Methods: A systematic review of PUBMED and EMBASE databases was conducted for studies reporting outcomes of intra-articular fractures in older adults. Data extracted included patient-reported outcome measures as well as clinical outcomes including ROM, adverse events and all-cause reoperation rates. Results: Forty-eight studies met the inclusion criteria and included 1838 acute, intra-articular distal humeral fractures. There was no clinically important difference in patient-reported pain and function measured on the Mayo Elbow Performance Score (TEA = 89.3 (SD 20.0), Hemi = 88.4 (SD 10.6), internal fixation = 85.0 (SD 14.7), non-operative = 85.1 (SD 11.0)). Discussion: Each of the treatment modalities studies resulted in a reasonable level of elbow function. The included studies were largely non-comparative and at considerable risk of bias. As elbow replacement surgery becomes centralised in the UK, there is a real need for high-quality comparative research studies to inform practice.

Part II: Blood Transfusion and Donor Exposure in the Surgical Management of Trigonocephaly Patients: A Protocol From Alder Hey Craniofacial Unit.

Trigonocephaly is a craniofacial malformation caused by premature fusion of the metopic suture. Surgical correction frequently results in the need for blood transfusion. Transfusion complications include transfusion-transmitted infections (TTIs), immune-mediated reactions, and volume overload. Donor exposure (DE) describes the number of blood products from unique donors with increasing DE equating to an increased risk of TTI. We evaluate data on 204 trigonocephaly patients covering 20 years of practice with respect to blood transfusions and DE. This represents the largest series from a single unit to date. A protocol based on our experiences has been devised that summarizes the key interventions we recommend to minimize blood transfusions and DE in craniofacial surgery. Patients operated on between 2000 and 2020 were included. DE and a range of values were calculated including estimated red cell loss (ERCL) and estimated red cell volume transfused (ERCVT). Groups were established by relevant interventions and compared using the Mann-Whitney U test. Mean DE fell from 1.46 at baseline to 0.85 ( P <0.05). Median allogenic transfusion volume fell from 350 mL at baseline to 250 mL ( P <0.05). Median ERCL fell from 15.05 mL/kg at baseline to 12.39 mL/kg and median ERCVT fell from 20.85 to 15.98 mL/kg. Changes in ERCL and ERCVT did not reach statistical significance. DE can be minimized with the introduction of key interventions such as a restrictive transfusion policy, preoperative iron, cell saver, tranexamic acid, and use of a matchstick burr for osteotomies.

Novel suture/suture-anchor fixation versus tension band wiring for olecranon fractures: A systematic review.

Introduction: Tension Band Wiring (TBW) has traditionally been the cornerstone of operative management for simple displaced olecranon fractures but its success is limited by high complication rates, mainly related to metalwork irritation and fixation failure. Over the last twelve years, a number of novel fixation methods not involving metalwork have been described in case series (suture fixation, SF and suture-anchor fixation, SAF) with promising early results. In this systematic review, the outcomes of SF and SAF techniques are presented alongside those for TBW for the treatment of closed olecranon fractures without elbow instability. Materials and methods: Five databases (Medline, Scholar, Scopus, Prospero and Cochrane) were searched for clinical studies involving TBW/SF/SAF for closed Mayo 1A/1B/2A/2B olecranon fractures from January 2010 onwards. Primary outcomes included overall complication and reoperation rates, as well as the rate of each specific complication. Elbow range of movement, surgeon and patient-reported outcome measures were defined as secondary outcomes. Results: Eighteen studies were included, nine of which involved SF/SAF (99 patients) and nine TBW (382 patients). SF/SAF techniques were associated with lower rates of fracture/implant displacement (2% versus 9.7%, p = 0.01), implant irritation (1% versus 30.1%, p < 0.001) and overall complications (8% versus 46.1%, p < 0.001) when compared to TBW. Reoperation rates were lower for SF/SAF (3% versus 37.2%, p < 0.001). Total flexion/extension arc achieved was similar (130.16 ± 2.11 versus 129.45 ± 0.93 degrees). On average, patients regained a functional arc of flexion (135.21 ± 4.81 TBW versus 131.32 ± 12.99 SF/SAF) and extension (1.16 ± 7.54 SF/SAF versus 5.76 ± 7.98 TBW). Conclusion: Current evidence suggests that SF/SAF of simple olecranon fractures is a safe and effective alternative to the current gold standard TBW fixation, with preliminary evidence suggestive of lower complication and reoperation rates. Firm conclusions of equivalence or superiority are not possible based on the current poor quality of literature available. Until the outcomes of high-quality prospective studies are available, patients should be carefully counselled that suture methods remain novel and outcomes should be regularly audited.

Serious adverse event rates and reoperation after arthroscopic shoulder surgery: population based cohort study.

OBJECTIVE: To provide clinicians and patients with accurate risk estimates of serious adverse events after common elective shoulder arthroscopic procedures, including reoperation within one year. DESIGN: Population based cohort study. SETTING: Hospital Episode Statistics for NHS England, including civil registration mortality data from the Office for National Statistics. PARTICIPANTS: 288 250 arthroscopic shoulder procedures performed in 261 248 patients aged ≥16 years between 1 April 2009 and 31 March 2017. Elective procedures were grouped into subacromial decompression, rotator cuff repair, acromioclavicular joint excision, glenohumeral stabilisation, and frozen shoulder release. MAIN OUTCOME MEASURES: The primary outcomes were rates of serious adverse events (mortality, pulmonary embolism, pneumonia, myocardial infarction, acute kidney injury, stroke, and urinary tract infection) requiring inpatient care within 90 days post-surgery. Secondary outcomes were specific adverse event rates at 90 days, and reoperations (including for deep infection) within one year. RESULTS: The overall rate of complications within 90 days after arthroscopic shoulder surgery (including reoperation) was low at 1.2% (95% confidence interval 1.2% to 1.3%), with one in 81 patients at risk, and varied according to type of procedure, from 0.6% (0.5% to 0.8%) for glenohumeral stabilisation to 1.7% (1.5% to 1.8%) for frozen shoulder release. After adjustment for age, comorbidities, and sex, no effect of procedure type was observed. Pneumonia was the most common adverse event (0.3%, 0.3% to 0.4%), with one in 303 patients at risk. Pulmonary embolic events were rare, at 0.1% (0.1% to 0.1%), with one in 1428 patients at risk. At one year, the overall rate for reoperation was 3.8% (3.8% to 3.9%), with one in 26 patients at risk, ranging from 2.7% (2.5% to 3.0%) for glenohumeral stabilisation to 5.7% (5.4% to 6.1%) for frozen shoulder release. The overall rate of further surgery for deep infection was low, at 0.1% (0.1% to 0.1%), with one in 1111 patients at risk, but was higher after rotator cuff repair (0.2%, 0.2% to 0.2%), with one in 526 patients at risk. Over the study period the number of arthroscopic shoulder procedures increased, except for subacromial decompression, which decreased. CONCLUSIONS: The findings of this study suggest that risks of serious adverse events associated with common shoulder arthroscopy procedures are low. Nevertheless, serious complications do occur, and include the risk of reoperation in one in 26 patients within one year. STUDY REGISTRATION: Clinical. TRIALS: gov NCT03573765.

The safe surgical margin in Ewing's sarcoma.

INTRODUCTION: There is recent evidence advocating the use of post-chemotherapy MRI for safe resection of primary bone sarcoma in providing a clear margin of disease. This paper challenges this view by providing evidence obtained from comparing surgical resection margin measurements calculated off the pre- and post-chemotherapy MRIs to the post-operative histological analysis. METHOD: A retrospective patho-radiological analysis of 10 patients treated for long bone Ewing's sarcoma. The pre- and post-chemotherapy MRI radiological measurements were correlated with the post-operative gross and microscopic histological specimens with the principle aim of determining which represented the accurate histological extent of disease and therefore which image set should be used in determining the surgical resection margins. RESULTS: In the 10 cases there was a discrepancy in the extent of pathological disease on comparative histological and radiological assessment. The mean age at presentation was 19.5years [4-45 years], with a female bias (n = 7/10). The lower limbs were more commonly involved than the upper limb (femur n = 2/10, tibia n = 3/10, fibula n = 2/10, humerus n = 2/10, ulna n = 1/10). There was no correlation between the percentage reduction in measured volume/length of pathological bone on sequential MRI and the percentage necrosis on histology. The average discrepancy between the length of pathological bone on histology and on MRI was 2.7 cm. Using the baseline pre-chemotherapy MRI to plan the surgical resection margins, 7/10 patients had their surgical resection margins through radiologically clear but pathologically abnormal bone (without histological evidence of residual tumour). Had the post-chemotherapy MRI been used a further 3 patients would have had their tumour resected through pathologically abnormal bone. No patients had or would have had tumour resected through residual tumour. CONCLUSIONS: The use of the post-chemotherapy MRI for planning surgical resection margins increases the risk of resecting through histologically abnormal bone that may have been previously contaminated by tumour, without significant benefit of preserving sufficient bone to facilitate joint or physeal sparing surgery. The evidence from this study supports current guidelines recommending the use of pre-chemotherapy MRI to plan safe surgical resection margins in Ewing's sarcoma.

Temporal Trends and Geographical Variation in Dupuytren Disease Surgery in England: A Population-Based Cohort Study.

BACKGROUND: Dupuytren disease (DD) is a common fibroproliferative disease of the palmar fascia. The mainstay of DD treatment in England is surgery with either percutaneous needle fasciotomy, limited fasciectomy, or dermofasciectomy. This study aimed to investigate the temporal trends and geographical variation of primary DD surgery in England. METHODS: A longitudinal population-based cohort study was perfomed using the Hospital Episode Statistics database from April 1, 2007, to March 31, 2017. Directly standarized rates were estimated over time (between financial years 2007-2008 and 2016-2017) and by geographic region (by clinical commissioning groups [CCGs]; financial years 2010-2011, 2013-2014, and 2016-2017). The Office for National Statistics midyear population estimates were used as the reference population. MAIN FINDINGS: Primary DD surgery was undertaken at a steadily increasing rate from financial year 2007 to 2008, to 2016 to 2017 in England. There was a striking 3.6-fold variation in the rates of primary DD surgery among National Health Service CCGs in England place of residence. CONCLUSIONS: This significant variation in DD surgical treatment in England suggests a need for the development of standardized surgical practice across all CCGs and National Health Service hospitals, promoting equality of access to cost-effective health care.

Low rates of serious complications and further procedures following surgery for base of thumb osteoarthritis: analysis of a national cohort of 43 076 surgeries.

OBJECTIVES: To determine the incidence of further procedures and serious adverse events (SAEs) requiring admission to hospital following elective surgery for base of thumb osteoarthritis (BTOA), and the patient factors associated with these outcomes. DESIGN: Population based cohort study. SETTING: National Health Service using the national Hospital Episode Statistics data set linked to mortality records over a 19-year period (01 April 1998-31 March 2017). PARTICIPANTS: 43 076 primary surgeries were followed longitudinally in secondary care until death or migration on 37 329 patients over 18 years of age. MAIN OUTCOME MEASURES: Incidence of further thumb base procedures (including revision surgery or intra-articular steroid injection) at any time postoperatively, and local wound complications and systemic events (myocardial infarction, stroke, respiratory tract infection, venous thromboembolic events, urinary tract infection or renal failure) within 30 and 90 days. To identify patient factors associated with outcome, Fine and Gray model regression analysis was used to adjust for the competing risk of mortality in addition to age, overall comorbidity and socioeconomic status. RESULTS: Over the 19 years, there was an increasing trend in surgeries undertaken. The rate of further thumb base procedures after any surgery was 1.39%; the lowest rates after simple trapeziectomy (1.12%), the highest rates after arthroplasty (3.84%) and arthrodesis (3.5%). When matched for age, comorbidity and socioeconomic status, those undergoing arthroplasty and arthrodesis were 2.5 times more likely to undergo a further procedure (subHR 2.51 (95% CI 1.81 to 3.48) and 2.55 (1.91 to 3.40)) than those undergoing simple trapeziectomy. Overall complication rates following surgery were 0.22% for serious local complications and 0.58% for systemic events within 90 days of surgery. CONCLUSIONS: The number of patients proceeding to BTOA surgery has increased over the last 19 years, with a low rate of further thumb base procedures and SAEs after surgery overall registered. Arthrodesis and arthroplasty had a significantly higher revision rate. TRIAL REGISTRATION NUMBER: NCT03573765.

Be Part of the Conversation: Audiology Messaging During a Hearing Screening.

OBJECTIVES: The moment patients learn the results from a hearing assessment can be a critical juncture on their journey to rehabilitation. Message framing (e.g., the positive or negative manner in which information is presented) has been explored in a wide range of health contexts as a method for shaping patients' decision-making. This study investigated whether attitudes toward hearing loss treatment varied as a function of how messages about treatment were framed, and whether such attitudes differed as a function of participants being led to believe they had failed a hearing screening. METHODS: Sixty-four participants (18 to 39 years of age) took the Hearing in Noise Test. In the sound booth, participants saw a poster bearing either a gain-framed or loss-framed message about hearing loss treatment. During the test, half the participants were interrupted by the researcher who stated that their performance appeared to suggest a hearing loss, with the caveat that it might be due to an equipment malfunction. While the researcher investigated the problem, the participants completed an 11-item questionnaire asking about their attitudes toward help seeking for hearing loss. Participants in the control group completed the same questionnaire with no interruption. RESULTS: Statistical analyses revealed no significant interaction effect between message type and experimenter feedback condition, though a significant main effect was present for message type. Post hoc testing showed medium to large effect sizes as a function of message type on five of the 11-questionnaire items. These data indicated that participants were more likely to endorse health-positive responses (i.e., greater interest in hearing treatment) when exposed to the gain-framed message than the loss-framed message. CONCLUSIONS: The greater likelihood of health-positive responses in the presence of the gain-framed message suggests that this framing strategy may have a positive influence on attitudes toward hearing health behaviors among individuals under 40 years of age with no history of hearing loss.

Low rate of subsequent surgery and serious complications following intra-articular steroid injection for base of thumb osteoarthritis: national cohort analysis.

OBJECTIVES: Intra-articular steroid injection is commonly used to treat base of thumb osteoarthritis (BTOA), despite a lack of large-scale data on safety and effectiveness. We estimate the incidence of serious complications and further procedures following BTOA injection, including the risk of post-operative serious surgical site infection for subsequent operative intervention. METHODS: Hospital Episode Statistics data linked to mortality records from 1 April 1998 to 31 March 2017 were used to identify all BTOA injections undertaken in adults in the National Health Service secondary care in England. Patients were followed up longitudinally until death or 31 March 2017. A multivariable regression with a Fine and Gray model adjusting for the competing risk of mortality in addition to age, sex and socioeconomic deprivation was used to identify factors associated with progression to further procedure. Secondary outcomes included serious complications after injection and subsequent surgical site infection. RESULTS: A total of 19 120 primary injections were performed during the 19-year period in 18 356 patients. Of these 76.5% were female; mean age 62 years (s.d. 10.6); 50.48% underwent further procedure; 22.40% underwent surgery. Median time to further intervention was 412 days (IQR 110-1945). Female sex was associated with increased risk of proceeding to surgery. Serious complication rate following injection was 0.04% (0.01-0.08) within 90 days. Of those proceeding to surgery 0.16% (0.06-0.34) presented with a wound infection within 30 days and 90 days, compared with an overall post-operative wound infection rate of 0.03% (0.02-0.05). CONCLUSIONS: Very low rates of serious complications were identified following BTOA injections performed in secondary care; only one in five patients proceeded to subsequent surgery.

Serious postoperative complications and reoperation after carpal tunnel decompression surgery in England: a nationwide cohort analysis.

BACKGROUND: Carpal tunnel decompression surgery to treat carpal tunnel syndrome is a common procedure, yet data on safety and effectiveness of the operation in the general population remain scarce. We aimed to estimate the incidence of reoperation and serious postoperative complications (requiring admission to hospital or further surgery) following carpal tunnel decompression in routine clinical practice and to identify the patient factors associated with these adverse outcomes. METHODS: We did a nationwide cohort analysis including all carpal tunnel decompression surgeries in patients aged 18 years or older, done in the National Health Service in England between April 1, 1998, and March 31, 2017, using the Hospital Episode Statistics dataset linked to mortality records. Patients were followed-up until death or until the end of the study (March 31, 2017). Primary outcomes were the overall incidence of carpal tunnel decompression reoperation and serious postoperative complications (surgical site infection or dehiscence, or neurovascular or tendon injury, requiring admission to hospital or further surgery) within 30 days and 90 days after surgery. Multivariable Cox regression analysis was used to identify factors influencing complications and reoperation, and the Fine and Gray method was used to adjust for the competing risk of mortality. This study is registered with ClinicalTrials.gov, NCT03573765. FINDINGS: 855 832 carpal tunnel decompression surgeries were done between April 1, 1998, and March 31, 2017 (incidence rate 1·10 per 1000 person-years [95% CI 1·02-1·17]). 29 288 procedures (3·42%) led to carpal tunnel decompression reoperation (incidence rate 3·18 per 1000 person-years [95% CI 3·12-3·23]). Of the 855 832 initial surgeries, 620 procedures (0·070% [95% CI 0·067-0·078]) led to a serious complication within 30 days after surgery, and 698 procedures (0·082% [0·076-0·088]) within 90 days. Local complications within 90 days after surgery were associated with male sex (adjusted hazard ratio 2·32 [95% CI 1·74-3·09]) and age category 18-29 years (2·25 [1·10-4·62]). Male sex (adjusted subhazard ratio 1·09 [95% CI 1·06-1·13]), old age (>80 years vs 50-59 years: 1·09 [1·03-1·15]), and greater levels of comorbidity (Charlson score ≥5 vs 0: 1·25 [1·19-1·32]) and socioeconomic deprivation (most deprived 10% vs least deprived 10%: 1·18 [1·10-1·27]) were associated with increased reoperation risk. INTERPRETATION: To our knowledge, this is the largest national study on carpal tunnel decompression to date, providing strong evidence on serious postoperative complication and reoperation rates. Carpal tunnel decompression appears to be a safe operation in most patients, with an overall serious complication rate (requiring admission to hospital or further surgery) of less than 0·1%.

Serious complications and risk of re-operation after Dupuytren's disease surgery: a population-based cohort study of 121,488 patients in England.

Dupuytren's disease (DD) is a common fibro-proliferative disorder of the palm. We estimated the risk of serious local and systemic complications and re-operation after DD surgery. We queried England's Hospital Episode Statistics database and included all adult DD patients who were surgically treated. A longitudinal cohort study and self-controlled case series were conducted. Between 1 April 2007 and 31 March 2017, 121,488 adults underwent 158,119 operations for DD. The cumulative incidence of 90-day serious local complications was low at 1.2% (95% CI 1.1-1.2). However, the amputation rate for re-operation by limited fasciectomy following dermofasciectomy was 8%. 90-day systemic complications were also uncommon at 0.78% (95% CI 0.74-0.83), however operations routinely performed under general or regional anaesthesia carried an increased risk of serious systemic complications such as myocardial infarction. Re-operation was lower than previous reports (33.7% for percutaneous needle fasciotomy, 19.5% for limited fasciectomy, and 18.2% for dermofasciectomy). Overall, DD surgery performed in England was safe; however, re-operation by after dermofasciectomy carries a high risk of amputation. Furthermore, whilst serious systemic complications were unusual, the data suggest that high-risk patients should undergo treatment under local anaesthesia. These data will inform better shared decision-making regarding this common condition.

Shoulder replacement surgery for osteoarthritis and rotator cuff tear arthropathy.

BACKGROUND: Shoulder replacement surgery is an established treatment for patients with end-stage glenohumeral osteoarthritis or rotator cuff tear arthropathy who have not improved with non-operative treatment. Different types of shoulder replacement are commonly used, but their relative benefits and risks compared versus one another and versus other treatments are uncertain. This expanded scope review is an update of a Cochrane Review first published in 2010. OBJECTIVES: To determine the benefits and harms of shoulder replacement surgery in adults with osteoarthritis (OA) of the shoulder, including rotator cuff tear arthropathy (RCTA). SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, SportDiscus, and Web of Science up to January 2019. We also searched clinical trial registers, conference proceedings, and reference lists from previous systematic reviews and included studies. SELECTION CRITERIA: We included randomised studies comparing any type of shoulder replacement surgery versus any other surgical or non-surgical treatment, no treatment, or placebo. We also included randomised studies comparing any type of shoulder replacement or technique versus another. Study participants were adults with osteoarthritis of the glenohumeral joint or rotator cuff tear arthropathy. We assessed the following major outcomes: pain, function, participant-rated global assessment of treatment success, quality of life, adverse events, serious adverse events, and risk of revision or re-operation or treatment failure. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. We collected trial data on benefits and harms. MAIN RESULTS: We included 20 studies involving 1083 participants (1105 shoulders). We found five studies comparing one type of shoulder replacement surgery to another type of shoulder replacement surgery, including three studies comparing conventional stemmed total shoulder replacement (TSR) surgery to stemmed humeral hemiarthroplasty. The remaining 15 studies compared one type of shoulder replacement to the same type of replacement performed with a technical modification or a different prosthetic component. We found no studies comparing shoulder replacement surgery to any other type of surgical treatment or to any type of non-surgical treatment. We found no studies comparing reverse total shoulder replacement surgery to any other type of treatment or to any type of replacement. Trial size varied from 16 to 161 participants. Participant mean age ranged from 63 to 81 years. 47% of participants were male. Sixteen trials reported participants with a diagnosis of osteoarthritis and intact rotator cuff tendons. Four trials reported patients with osteoarthritis and a rotator cuff tear or rotator cuff tear arthropathy. All studies were at unclear or high risk of bias for at least two domains, and only one study was free from high risk of bias (included in the main comparison). The most common sources of bias were lack of blinding of participants and assessors, attrition, and major baseline imbalance. Three studies allowed a comparison of conventional stemmed TSR surgery versus stemmed humeral hemiarthroplasty in people with osteoarthritis. At two years, low-quality evidence from two trials (downgraded for bias and imprecision) suggested there may be a small but clinically uncertain improvement in pain and function. On a scale of 0 to 10 (0 is no pain), mean pain was 2.78 points after stemmed humeral hemiarthroplasty and 1.49 points lower (0.1 lower to 2.88 lower) after conventional stemmed TSR. On a scale of 0 to 100 (100 = normal function), the mean function score was 72.8 points after stemmed humeral hemiarthroplasty and 10.57 points higher (2.11 higher to 19.02 higher) after conventional stemmed TSR. There may be no difference in quality of life based on low-quality evidence, downgraded for risk of bias and imprecision. On a scale of 0 to 100 (100 = normal), mean mental quality of life was rated as 57.4 points after stemmed humeral hemiarthroplasty and 1.0 point higher (5.1 lower to 7.1 higher) after conventional stemmed TSR. We are uncertain whether there is any difference in the rate of adverse events or the rate of revision, re-operation, or treatment failure based on very low-quality evidence (downgraded three levels for risk of bias and serious imprecision). The rate of any adverse event following stemmed humeral hemiarthroplasty was 286 per 1000, and following conventional stemmed TSR 143 per 1000, for an absolute difference of 14% fewer events (25% fewer to 21% more). Adverse events included fractures, dislocations, infections, and rotator cuff failure. The rate of revision, re-operation, or treatment failure was 103 per 1000, and following conventional stemmed TSR 77 per 1000, for an absolute difference of 2.6% fewer events (8% fewer to 15% more). Participant-rated global assessment of treatment success was not reported. AUTHORS' CONCLUSIONS: Although it is an established procedure, no high-quality randomised trials have been conducted to determine whether shoulder replacement might be more effective than other treatments for osteoarthritis or rotator cuff tear arthropathy of the shoulder. We remain uncertain about which type or technique of shoulder replacement surgery is most effective in different situations. When humeral hemiarthroplasty was compared to TSR surgery for osteoarthritis, low-quality evidence led to uncertainty about whether there is a clinically important benefit for patient-reported pain or function and suggested there may be little or no difference in quality of life. Evidence is insufficient to show whether TSR is associated with greater or less risk of harm than humeral hemiarthroplasty. Available randomised studies did not provide sufficient data to reliably inform conclusions about adverse events and harm. Although reverse TSR is now the most commonly performed type of shoulder replacement, we found no studies comparing reverse TSR to any other type of treatment.

Incidence, temporal trends and potential risk factors for prosthetic joint infection after primary total shoulder and elbow replacement: Systematic review and meta-analysis.

OBJECTIVES: We conducted a systematic meta-analysis to evaluate the incidence, temporal trends and potential risk factors for prosthetic joint infection (PJI) following primary total shoulder replacement (TSR) and elbow replacement (TER). METHODS: Longitudinal studies reporting infection outcomes following primary TSR or TER were sought from MEDLINE, Embase and Cochrane Library up to June 2019. Incidence rates and relative risks (with 95% CIs) were calculated. RESULTS: The search identified 105 eligible articles (108 non-overlapping studies). There were 631,854 TSRs (1,751 PJIs) and 17,485 TERs (525 PJIs). The pooled PJI incidence following TSR was 0.61% (0.34-0.93) over a follow-up period of 1.1 years. The corresponding incidence following TER was 2.53% (1.99-3.12) over a follow-up period of 3.3 years. Shoulder and elbow PJI incidence declined from the 1990s to 2010 and beyond. Males, younger age (<75 years), previous shoulder surgery, reverse TSR, rotator cuff arthropathy and inpatient TSR increased shoulder PJI risk. For TER, high body mass index, psychiatric illness, and previous elbow surgery increased PJI risk. CONCLUSIONS: Shoulder and elbow PJI may be on a temporal decline. Caution should be taken for patients at high PJI risk following primary TSR such as younger males and patients with a previous shoulder surgery.

How long does a shoulder replacement last? A systematic review and meta-analysis of case series and national registry reports with more than 10 years of follow-up.

BACKGROUND: Shoulder replacement is an increasingly common treatment for end-stage degenerative shoulder conditions. Some shoulder replacements are unsuccessful and additional operations might be required. It is important for patients and clinicians to know how long shoulder replacements last and how effectively they reduce pain and improve function. This study aims to determine the longevity and long-term efficacy of shoulder replacements. METHODS: In this systematic review and meta-analysis, we searched MEDLINE and Embase from their inception to Sept 24, 2019, for case series and registry data reporting 10-year or longer survival of total shoulder replacements, humeral hemiarthroplasties, and reverse total shoulder replacements of a specific brand of implant. Survival, implant, and patient-reported outcome measures data were extracted. The primary outcome was implant survival. We reviewed and analysed national joint replacement registries separately. We weighted each series by SE and calculated a pooled survival estimate at years 10, 15, and 20. For patient-reported outcome measures we pooled the standardised mean difference at 10 years. This study is registered with PROSPERO, CRD42019140221. FINDINGS: 927 non-duplicate articles were identified by our search, nine articles (reporting ten series) were eligible for analysis of survival and six articles were eligible for analysis of patient reported outcomes. The ten series reported all-cause survival of 529 total shoulder replacements and 364 humeral hemiarthroplasties; no series for reverse total shoulder replacement met the inclusion criteria. The estimated 10-year survival for total shoulder replacement was 94·6% (95% CI 93·6-97·6) and humeral hemiarthroplasties was 90·4% (87·0-94·0). A single registry contributed 7651 total shoulder replacements, 1395 humeral hemiarthroplasties, and 7953 reverse total shoulder replacements. The pooled registry 10-year survival was 92·0% (95% CI 91·0-93·0) for total shoulder replacement, 85·5% (83·3-87·7) for humeral hemiarthroplasties, and 94·4% (93·4-95·7) for patients with osteoarthritis who had reverse total shoulder replacement and 93·6% (91·1-95·8) for patients with rotator cuff arthropathy who had reverse total shoulder replacement. Pooled 10-year patient-reported outcome measures showed a substantial improvement from baseline scores, with a standardised mean difference of 2·13 (95% CI 1·93-2·34). INTERPRETATION: Our data show that approximately 90% of shoulder replacements last for longer than 10 years and patient-reported benefits are sustained. Our findings will be of use to surgeons and patients in the informed consent process and to health-care providers for resource planning.

Serious adverse events and lifetime risk of reoperation after elective shoulder replacement: population based cohort study using hospital episode statistics for England.

OBJECTIVES: To provide accurate risk estimates of serious adverse events after elective shoulder replacement surgery for arthritis, including age and sex specific estimates of the lifetime risk of revision surgery. DESIGN: Population based cohort study. SETTING: Hospital episode statistics for NHS England, including civil registration mortality data. PARTICIPANTS: 58 054 elective shoulder replacements in 51 895 adults (aged ≥50 years) between April 1998 and April 2017. MAIN OUTCOME MEASURES: The lifetime risk of revision surgery, calculated using an actuarial life table approach and the cumulative probability method. Rates of serious adverse events at 30 and 90 days post-surgery: pulmonary embolism, myocardial infarction, lower respiratory tract infection, acute kidney injury, urinary tract infection, cerebrovascular events, and all cause death. Secondary outcome measures were the number of surgeries performed each year and Kaplan-Meier estimates of revision risk at 3, 5, 10, and 15 years. RESULTS: The number of shoulder replacements performed each year increased 5.6-fold between 1998 and 2017. Lifetime risks of revision surgery ranged from 1 in 37 (2.7%, 95% confidence interval 2.6% to 2.8%) in women aged 85 years and older to 1 in 4 (23.6%, 23.2% to 24.0%) in men aged 55-59 years. The risks of revision were highest during the first five years after surgery. The risk of any serious adverse event at 30 days post-surgery was 1 in 28 (3.5%, 3.4% to 3.7%), and at 90 days post-surgery was 1 in 22 (4.6%, 4.4% to 4.8%). At 30 days, the relative risk of pulmonary embolism compared with baseline population risk was 61 (95% confidence interval 50 to 73) for women aged 50-64. Serious adverse events were associated with increasing age, comorbidity, and male sex. 1 in 5 (21.2%, 17.9% to 25.1%) men aged 85 years and older experienced at least one serious adverse event within 90 days. CONCLUSIONS: Younger patients, particularly men, need to be aware of a higher likelihood of early failure of shoulder replacement and the need for further and more complex revision replacement surgery. All patients should be counselled about the risks of serious adverse events. These risks are higher than previously considered, and for some could outweigh any potential benefits. Our findings caution against unchecked expansion of shoulder replacement surgery in both younger and older patients. The more accurate age and sex specific estimates of risk from this study are long overdue and should improve shared decision making between patients and clinicians.

Metal wear-induced pseudotumour following an endoprosthetic knee replacement for Ewing sarcoma.

Pseudotumours are well recognised as a complication of metal-on-metal hip arthroplasties and are thought to develop on the basis of an innate and adaptive immune response to cobalt-chrome (Co-Cr) wear particles. We report a case of a large pseudotumour that developed following a knee endoprosthetic replacement (EPR) undertaken for Ewing sarcoma. The lesion contained necrotic and degenerate connective tissue in which there were numerous scattered metal wear-containing macrophages, eosinophil polymorphs, lymphocytes, plasma cells and aseptic lymphocyte-dominated vascular-associated lesion-like lymphoid aggregates. Metal ion levels were elevated. No evidence of infection or tumour was noted and it was concluded that the lesion was most likely an inflammatory pseudotumour developing on the basis of an innate and adaptive immune response to components of Co-Cr metal wear derived from the knee EPR.

Improving the mental health of rural New South Wales communities facing drought and other adversities.

OBJECTIVE: NSW has just experienced its worst drought in a century. As years passed with insufficient rain, drought-related mental health problems became evident on farms. Our objective is to describe how, in response, the Rural Adversity Mental Health Program was introduced in 2007 to raise awareness of drought-related mental health needs and help address these needs in rural and remote NSW. The program has since expanded to include other forms of rural adversity, including recent floods. SETTING: Rural NSW. DESIGN, PARTICIPANTS, INTERVENTIONS: Designed around community development principles, health, local service networks and partner agencies collaborated to promote mental health, education and early intervention. Strategies included raising mental health literacy, organising community social events and disseminating drought-related information. Priority areas were Aboriginal communities, older farmers, young people, women, primary health care and substance use. RESULTS: Over 3000 people received mental health literacy training in the four years of operation from 2007 to 2010. Stakeholders collaborated to conduct hundreds of mental health-related events attended by thousands of people. A free rural mental health support telephone line provided crisis help and referral to rural mental health-related services. CONCLUSION: Drought affected mental health in rural NSW. A community development model was accepted and considered effective in helping communities build capacity and resilience in the face of chronic drought-related hardship. Given the scale, complexity and significance of drought impacts and rural adjustment, and the threats posed by climate change, a long-term approach to funding such programs would be appropriate.
