Abstract
PURPOSE Given the poor soft-tissue quality in rheumatoid arthritis patients, many believe that rheumatoid arthritis should be treated with reverse total shoulder arthroplasty (rTSA). The purpose of this paper is to systematically assess outcomes of anatomic total shoulder arthroplasty (aTSA) in rheumatoid arthritis to determine if aTSA remains a viable option. METHODS A comprehensive literature search was conducted identifying articles relevant to aTSA in the setting of rheumatoid arthritis with intact rotator cuff. Outcomes include clinical outcomes and rates of complication and revision. RESULTS Ten studies were included with a total of 279 shoulders with mean follow-up of 116 ± 69 months. The mean age was 68 ± 10 years. Survivorship was 97%, 97% and 89% at 5, 10 and 20 years, respectively. The overall complication rate was 9%. Radiolucency was present in 69% of patients, of which 34% were at risk of loosening at 79 months. The overall rate of revision was 8.4%. Studies generally reported clinically significant improvements in range of motion, Constant score and ASES score. CONCLUSION aTSA in the rheumatoid patient results in improvements in range of motion and patient-reported outcomes. Rates of complications and survivorship are generally good in this population. However, it should be noted that there is significant heterogeneity in outcome reporting amongst the literature on this topic and that many studies fail to adequately report complication and revision rates. When compared to rTSA in patients with rheumatoid arthritis, evidence suggests that aTSA is still a viable treatment option despite the shift in utilization to rTSA.

[PMID: 33717222 PMCID: PMC7905516 DOI: 10.1177/1758573219897860] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Revised: 10/16/2019] [Accepted: 12/08/2019] [Indexed: 11/16/2022]
Abstract
BACKGROUND The primary aim of this study was to determine the cost-effectiveness of the reverse total shoulder arthroplasty in a prospective cohort of patients over a two-year post-operative period. METHODS Patients who underwent reverse total shoulder arthroplasty were prospectively monitored for 24 months post-operatively using the Oxford Shoulder Score, Disabilities of the Arm, Shoulder and Hand questionnaire and EuroQol 5-dimensional questionnaire. Any complications or use of health care resources were recorded. The incremental cost-effectiveness ratio was used to express the cost per quality-adjusted life year gained. RESULTS Sixty-seven patients were analysed, 46 primary reverse total shoulder arthroplasty for cuff arthropathy and 21 revisions from previous arthroplasty. Both indications had comparable peri-operative shoulder scores without significant difference. Using the mean change of EuroQol 5-dimensional questionnaire at one year, the incremental cost-effectiveness ratio was calculated at £16,827.43 per quality-adjusted life year, decreasing to £8313.48 per quality-adjusted life year at two years. Primary was associated with a lower incremental cost-effectiveness ratio at two years (primary £7596.76 vs. revision £11,748.51). The estimated post-operative life expectancy of the cohort was 6.9 years with a projected cost per quality-adjusted life year of £2438.78. CONCLUSIONS Reverse total shoulder arthroplasty provides a cost-effective intervention with excellent patient outcomes at two years post-operatively.

Abstract
Background Though total shoulder arthroplasty (TSA) has been an acknowledged treatment option for glenohumeral osteoarthritis, resurfacing hemiarthroplasty (RHA) and stemmed hemiarthroplasty (SHA) may be preferred in some circumstances by surgeons, especially for treating young or active patients. However, decision-making between the RHA and SHA is controversial. Therefore, we conducted a meta-analysis to systematically compare two surgical procedures in terms of postoperative functional outcomes, range of motion (ROM), pain relief, complication rates, risk of revision. Methods The PubMed, Embase, Web of Science and Cochrane Library were searched from inception to January 1, 2020, for all articles that compared the clinical effectiveness and safety of RHA with SHA. All eligible studies were selected based on certain screening criteria. Two investigators independently conducted the quality assessment and extracted the data. Fixed-effect and random-effect models were used for pooled results according to the degree of heterogeneity. All statistical analyses were performed by employing Stata software 14.0. Results A total of six comparative studies involving 2568 shoulders (1356 RHA and 1212 SHA) were included in the final analysis. Patients were followed up for at least 1 year in each study. Pooled results showed that RHA was associated with a better visual analog scale (SMD 0.61, p = 0.001) but higher revision rates (OR 1.50, p = 0.016) when compared to SHA. There were no significant differences in functional outcomes, such as Constant-Murley score (SMD 0.06, P = 0.878), American Shoulder and Elbow Surgeons score (SMD 0.05, P = 0.880), Western Ontario Osteoarthritis of the Shoulder index (SMD 0.43, p = 0.258) and quick-Disabilities of the Arm, Shoulder and Hand score (SMD 0.06, p = 0.669). In addition, no differences were observed in forward flexion (SMD 0.16, p = 0.622), external rotation (SMD -0.17, P = 0.741) and overall complication rates (OR 1.42, p = 0.198). Conclusion This is the first meta-analysis to investigate the clinical efficacy and safety of RHA in comparison with SHA for the treatment of glenohumeral osteoarthritis. The results demonstrated that the two surgical techniques were equivalent in terms of postoperative functional outcomes and complication rate. However, RHA provided greater pain relief but posed a higher risk for revision than SHA. More high-quality studies with long-term follow up are warranted to give more convincing evidence.

Abstract
INTRODUCTION Shoulder arthroplasty rates are increasing in the UK. No data have been published from a UK centre on predictors of length of inpatient stay following shoulder arthroplasty. This study analyses the length of inpatient stay following shoulder arthroplasty in a high-volume UK centre and identifies predictors of prolonged inpatient stay. MATERIALS AND METHODS All shoulder arthroplasty cases performed between 2012 and 2018 were identified. A review of case notes and electronic patient records was completed to identify demographic data, Charlson comorbidity score, length of inpatient stay and factors associated with length of stay. Multiple linear regression analysis was conducted to determine which factors were independently associated with length of inpatient stay. RESULTS A total of 640 shoulder arthroplasty cases were performed in 566 patients. Median length of stay was two days. Length of stay was predicted by age, sex, chronic kidney disease, congestive cardiac failure, previous myocardial infarction, intraoperative complication and postoperative transfusion. DISCUSSION Increasing age, female sex, chronic kidney disease, congestive cardiac failure, previous myocardial infarction, intraoperative complication and transfusion were independent predictors of increased length of stay. Strategies to reduce perioperative complication and transfusion, and to optimise renal and cardiac comorbidities may reduce overall length of stay for shoulder arthroplasty patients.

Abstract
Background and purpose - Osteoarthritis has become the most common indication for shoulder arthroplasty in Denmark, and the treatment strategies have changed towards the use of anatomical total shoulder arthroplasty and reverse shoulder arthroplasty. We investigated whether changes in the use of arthroplasty types have changed the overall patient-reported outcome from 2006 to 2015. Patients and methods - We included 2,867 shoulder arthroplasties performed for osteoarthritis between 2006 and 2015 and reported to the Danish Shoulder Arthroplasty Registry. The Western Ontario Osteoarthritis of the Shoulder (WOOS) index at 1 year was used as patient-reported outcome. The raw score was converted to a percentage of a maximum score. General linear models were used to analyze differences in WOOS. Results - The proportion of anatomical total shoulder arthroplasty and reverse shoulder arthroplasty increased from 3% and 7% in 2006 to 53% and 27% in 2015. The mean WOOS score was 70 (SD 26) after resurfacing hemiarthroplasties (n = 1,258), 68 (SD 26) after stemmed hemiarthroplasty (n = 500), 82 (SD 23) after anatomical total shoulder arthroplasties (n = 815), and 74 (SD 23) after reverse shoulder arthroplasties (n = 213). During the study period, the overall WOOS score increased with 18 (95% CI 12-22) in the univariate model and 10 (CI 5-15) in the multivariable model, and the WOOS scores for anatomical total shoulder arthroplasty increased by 14 (CI 5-23). Interpretation - We found an increased WOOS score from 2006 to 2015, which was primarily related to a higher proportion of anatomical total shoulder arthroplasty and reverse shoulder arthroplasty towards the end of the study period, and to improved outcome of anatomical total shoulder arthroplasty.

Abstract
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.

Abstract
Background Humeral head resurfacing (HHR) has emerged as an alternative treatment for glenohumeral osteoarthritis. We investigated the outcomes of HHR using validated patient-reported outcome (PRO) measures. Methods A retrospective review was performed on 213 patients who underwent HHR. A PRO follow-up was performed by administering a questionnaire including the American Shoulder and Elbow Society (ASES) score, Brophy activity survey, short form of the Disabilities of the Arm, Shoulder and Hand (quickDASH) survey, and general shoulder function. PRO scores were stratified by comorbidities and complications. Results Survey responses were received from 106 patients (51%), with a mean follow-up of 5.6 ± 1.8 years (range: 9 months to 6.1 years). Preoperative comorbidities were associated with significantly higher quickDASH scores. Postoperative complications were associated with significantly higher rates of current pain, higher visual analog scale scores, night pain, lower subjective shoulder values, and lower ASES pain and total scores. No differences in patient satisfaction were identified between the cohorts with and without preoperative comorbidities and between the cohorts with and without postoperative complications. Conclusion In our cross-sectional analysis of mid- to long-term outcomes following HHR, preoperative comorbidities, or postoperative complications had no impact on patient-perceived postoperative satisfaction or most PROs. HHR is clinically viable in a wide variety of patients. Future work is necessary to compare the efficacy of HHR compared with more traditional total shoulder arthroplasty and stemmed hemiarthroplasty regarding long-term outcomes and appropriate indications.

Abstract
Shoulder arthroplasty is a valuable option for treating glenohumeral osteoarthritis. Revision surgery for a failed shoulder arthroplasty is associated with difficult procedures, complications, and worse outcomes. Compared with a total joint arthroplasty, a resurfacing prosthesis has the supposed advantages of limited perioperative complications and little bone loss during revision. The aim of this study was to describe patient-reported outcome measures of revision surgery from failed uncemented Global CAP (DePuy, Warsaw, Indiana) resurfacing hemiarthroplasty to total shoulder or reverse shoulder arthroplasty. Eleven patients from 2 collaborating institutes had a failed resurfacing prosthesis. Revision surgery was performed to total shoulder prosthesis in 7 patients and to reverse shoulder prosthesis in 3 patients. Data were missing for 1 patient. Outcomes were monitored using the Constant-Murley score, Dutch Simple Shoulder Test, Short Form-12, visual analog scale for pain, and physical examination. Mean time to revision was 54 months (SD, 15.6 months). No perioperative complications occurred. At 42 months of follow-up (SD, 15.9 months), clinical and patient-reported outcomes were excellent. The Constant-Murley score improved a significant 29 points (P<.01). The visual analog scale pain score decreased from 55 to 5 points (P<.01), and the Dutch Simple Shoulder Test and Short Form-12 scores improved significantly (P≤.02). Five-year survival was 82.6% (95% confidence interval, 71.6%-93.6%). At 3.5-year follow-up, clinical and patient-reported outcome measures had satisfying results.

Abstract
Background In a clinical setting, a visual evaluation of post-implant radiographs is often used to assess the restoration of glenohumeral joint anatomy after resurfacing hemiarthroplasty and is a part of the decision-making process, in combination with other parameters, when evaluating patients with inferior clinical results. However, the reliability of this method of visual evaluation has not been reported. The aim of this study was to investigate the inter- and intra-observer agreement among experienced shoulder surgeons assessing overstuffing, implant positioning, and size following resurfacing hemiarthroplasty using plain standardized radiographs. Methods Six experienced shoulder surgeons independently classified implant inclination, size of the implant and if the joint seemed overstuffed, in 219 cases of post-implant radiographs. All cases were classified twice 3 weeks apart. Only radiographs with an anterior-posterior projection with a freely visible joint space were used. Non-weighted Cohen’s kappa values were calculated for each coder pair and the mean used as an estimate of the overall inter-observer agreement. Results The overall inter-observer agreement for implant size (kappa, 0.48 and 0.41) and inclination angle was moderate in both rounds (kappa, 0.46 and 0.44), but only a fair agreement was found concerning the evaluation for stuffing of the joint (kappa, 0.24 and 0.28). Intra-observer agreement for implant size and stuffing ranged from fair to substantial while the agreement for inclination was moderate to substantial. Conclusions Our results indicate that a visual evaluation of plain radiographs may be inadequate to evaluate overstuffing, implant positioning, and size following resurfacing hemiarthroplasty using plain standardized radiographs. Future studies may contribute to elucidate whether reliability increases if consensus on clear definitions and standardized methods of evaluation is made.

Abstract
INTRODUCTION The EuroQol-5 Dimension (EQ-5D) is the most widely used generic instrument to measure quality of life (QoL), yet its application in upper extremity orthopaedics as well as its measurement properties remain largely undefined. We implemented a systematic literature review to provide an overview of the application of EQ-5D in patients with upper extremity disorders and analyse its measurement properties. MATERIALS AND METHODS We searched Medline, EMBASE, Cochrane and Scopus databases for clinical studies including orthopaedic patients with surgical interventions of the upper extremity who completed the EQ-5D. For all included studies, the use of EQ-5D and quantitative QoL data were described. Validation studies of EQ-5D were assessed according to COSMIN guidelines and standard measurement properties were examined. RESULTS Twenty-three studies were included in the review, 19 of which investigated patients with an intervention carried out at the shoulder region. In 15 studies, EQ-5D assessed QoL as the primary outcome. Utility index scores in non-trauma patients generally improved postoperatively, whereas trauma patients did not regain their recalled pre-injury QoL levels. EQ-5D measurement properties were reported in three articles on proximal humerus fractures and carpal tunnel syndrome. Positive ratings were seen for construct validity (Spearman correlation coefficient ≥ 0.70 with the Short Form (SF)-12 or SF-6D health surveys) and reliability (intraclass correlation coefficient ≥ 0.77) with intermediate responsiveness (standardised response means: 0.5-0.9). However, ceiling effects were identified with 16-48% of the patients scoring the maximum QoL. The methodological quality of the three articles varied from fair to good. CONCLUSIONS For surgical interventions of the upper extremity, EQ-5D was mostly applied to assess QoL as a primary outcome in patients with shoulder disorders. Investigations of the measurement properties were rare, but indicate good reliability and validity as well as moderate responsiveness in patients with upper extremity conditions.

Shoulder Elbow 2017; 9:153-159. [PMID: 28588655 PMCID: PMC5444608 DOI: 10.1177/1758573217700833] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Revised: 12/15/2016] [Accepted: 02/17/2017] [Indexed: 11/15/2022]
Abstract
BACKGROUND The present study aimed to review the biomechanical outcomes of subscapularis repair techniques during total shoulder arthroplasty (TSA) to assist in clinical decision making. METHODS A systematic review of multiple databases was performed by searching PubMed, Scopus, Cochrane Library, Google Scholar, and all databases within EBSCOhost to find biomechanical studies of subscapularis repair techniques in cadaveric models of TSA. RESULTS Nine studies met the inclusion criteria. In the majority of studies, lesser tuberosity osteotomy (LTO) techniques had greater load to failure and less cyclic displacement compared to subscapularis tenotomy or peel methods. LTO repairs with sutures wrapped around the humeral stem demonstrated superior biomechanical outcomes compared to techniques using only a tension band. In terms of load to failure, the strongest repair of any study was a dual-row fleck LTO using four sutures wrapped around the stem. CONCLUSIONS Several cadaveric studies have shown superior biomechanical outcomes with LTO techniques compared to tenotomy. In the majority of studies, the strongest subscapularis repair technique in terms of biomechanical outcomes is a compression LTO. Using three or more sutures wrapped around the implant and the addition of a tension suture may increase the biomechanical strength of the LTO repair.

Abstract
INTRODUCTION Although humeral head resurfacing with a cap is relatively common in clinical practice, clinical studies about the changes of the bone are rare. The aim of this study was to analyse qualitative and quantitative changes of the bone after cup arthroplasty. Our hypothesis is that the implant leads to a new functional load with remarkable changes of the bone underneath the cap. MATERIAL AND METHODS Overall, 12 explanted caps with adherent bone tissues, retrieved at the revision surgery, were collected for histological examination. None of these implants were revised for loosening. Afterwards, there was a qualitative evaluation of the bone as well an assessment of established quantitative bone tissue parameters. Results were analyzed in correlation to the time to revision surgery, as well as to patient's age. RESULTS A significant decrease of the bone volume and trabecular architecture underneath the cap was already observed after a relatively short lifetime. The quantitatively measured bone loss does not depend on the patient's age, but correlates significantly with the lifetime of the implants. In contrast to these findings within the central areas, an increased bone remodeling with bone densifications and microcallus formations was noticed at the edge of the cap in most cases. DISCUSSION A significant reduction of the bone volume underneath the cap and remarkable changes of the trabecular architecture confirm our hypothesis. Even if these changes did not lead to a clinically relevant loosening in our series, they might influence revision surgeries. Thus, these findings might be of interest, especially when a non-stemmed reversed or anatomical revision arthroplasty with a central metaphyseal press-fit fixation is chosen. LEVEL OF EVIDENCE IV - retrospective or historical series.

Radiological and functional 24-month outcomes of resurfacing versus stemmed anatomic total shoulder arthroplasty. INTERNATIONAL ORTHOPAEDICS 2016; 41:375-384. [PMID: 27761628 DOI: 10.1007/s00264-016-3310-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2016] [Accepted: 09/27/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE This study compared clinical and radiographic outcomes of patients undergoing resurfacing total shoulder arthroplasty (TSA) with those treated with a stemmed TSA. METHODS Patients with primary osteoarthritis who underwent humeral resurfacing (RES) or stemmed (STA) TSA were identified in our shoulder arthroplasty register for retrospective analysis. Standard radiographs and clinical/patient-rated assessments were made up to 24 months post-surgery. Implant revisions were assessed. Patients were frequency-matched in a 1:1 (RES:STA) ratio based on gender and age, and compared with regard to operation time and shoulder function (Constant, SPADI and Quick DASH scores). Mixed models with statistical adjustments were applied. RESULTS From 2006 to 2014, 44 RES and 137 STA operations were performed in 157 patients; one and two revisions were recorded in the RES and STA group, respectively. The final matched cohort included a total of 69 patients and 37 operations per treatment group. Resurfacing TSA was 17 min shorter (95%CI: 5-28) compared to the stemmed procedure (p = 0.005). RES and STA patients showed significant functional improvement six months post-implantation, yet all measured scores did not differ between the groups at 2 years (p ≥ 0.131). The status of static centering of the humeral head, acromiohumeral distance, and a lack of signs of implant loosening were also similar between treatments. CONCLUSION Similar 24-month post-operative radiological and functional outcome is achieved by RES and STA patients, even with a shorter RES surgery time. Larger cohorts and longer follow-up are required to better assess implant survival.

Abstract
BACKGROUND Reverse total shoulder arthroplasty (RTSA) is increasingly being performed. Many patients may wish to return to high levels of sporting activity. This study aimed to evaluate the correlation of isokinetic shoulder strength with level of participation in sport and recreation after RTSA. METHODS We surveyed 51 patients at a mean of 29.5 months (range, 12-60 months) after surgery. Mean age was 74.1 years. Patient-reported sporting activity was classified as low, medium, or high demand. All patients completed the shortened Disabilities of the Arm, Shoulder, and Hand questionnaire and the Oxford Shoulder Score and underwent Biodex dynamometer testing of the RTSA evaluating isokinetic shoulder strength in flexion and extension, abduction and adduction, and internal and external rotation. RESULTS Reported sporting activity was high demand in 35% and moderate demand in 43%. There was a large variation in shoulder isokinetic strength parameters especially for internal and external rotation. With the exception of abduction, a significant correlation was noted between strength and the level of sports participation that patients reported (P < .03). A significant correlation was also noted between strength and patient-reported outcome measures for internal rotation and arm flexion and abduction (P < .05). CONCLUSION Most patients reported returning to moderate- or high-level sporting activity in the short term after RTSA. Isokinetic shoulder strength, especially in internal rotation and arm flexion, positively correlates with both patient-reported level of participation in sports and recreation and daily function.

Abstract
INTRODUCTION The field of shoulder endoprothetics has undergone a rapid development in the last years. The purpose of the study was to provide an overview of the development of shoulder arthroplasties in Germany from 2005 until 2012. This study hypothesized that the surgical procedures of the shoulder joint is still increasing and have not reached a plateau until 2012. METHODS Data of the German federal statistical office from 2005 until 2012 were analyzed to quantify hemiarthroplasty, anatomic total shoulder and reversed total shoulder arthroplasty rates depending on age, gender and main coded indications. Procedure codes and diagnosis were analyzed for each year. Comparative analyses were used to visualize the difference between the types of shoulder endoprostheses. RESULTS A total number of 139.272 shoulder arthroplasties were performed between 2005 and 2012. Total should arthroplasties have increased continuously until 2009. In 2009 more total shoulder arthroplasties have been performed than hemiprothesis implantations, which have culminated in 2008. All in all, women have been treated 3-fold higher than men regarding hemiarthroplasty, total shoulder arthroplasties or reversed total shoulder arthroplasties. Under the age of 60 years the majority of treated patients were male. CONCLUSION Since 2005 shoulder arthroplasties are still increasing in Germany, whereas a slight reduction could be detected for shoulder hemiarthroplasty from 2009 up until 2012. Meanwhile total shoulder arthroplasties and reversed total shoulder arthroplasties are still increasing. Women have experienced a 3-fold higher hemiarthroplasty, total shoulder and reversed shoulder arthroplasties than men except for individual younger than 60 years.

Abstract
BACKGROUND AND PURPOSE Shoulder arthroplasty is being performed in the United States with increasing frequency. We describe the medium-term findings from a large integrated healthcare system shoulder arthroplasty registry. PATIENTS AND METHODS Shoulder arthroplasty cases registered between January 2005 and June 2013 were included for analysis. The registry included patient characteristics, surgical information, implant data, attrition, and patient outcomes such as surgical site infections, venous thromboembolism, and revision procedures. RESULTS During the study period, 6,336 primary cases were registered. Median follow-up time for all primaries was 3.3 years; 461 cases were lost to follow-up by ending of health plan membership. Primary cases were predominantly female (56%) and white (81%), with an average age of 70 years. The most common reason for surgery was osteoarthritis in 60% of cases, followed by acute fracture (17%) and rotator cuff tear arthropathy (15%). In elective shoulder arthroplasty procedures, 200 all-cause revisions (4%) were reported, with glenoid wear being the most common reason. INTERPRETATION Most arthroplasties were elective procedures: over half performed for osteoarthritis. Glenoid wear was the most common reason for revision of primary shoulder arthroplasty in elective cases.

Abstract
BACKGROUND AND PURPOSE Persistent postsurgical pain is a well-recognized problem after various types of surgery such as amputation and thoracotomy. The prevalence of persistent pain, and the extent to which it involves neuropathic pain, is highly dependent on the type of surgery. We investigated the prevalence of, characteristics of, and risk factors for persistent pain 1-2 years after shoulder replacement. PATIENTS AND METHODS A questionnaire was sent to patients who underwent primary shoulder replacement between April 2011 and April 2012, and whose data were recorded in the Danish Shoulder Arthroplasty Register. Patients who had undergone reoperation or bilateral replacements were excluded. Persistent pain was defined as constant or daily pain within the last month, which interfered much or very much with daily activities. Multivariate logistic regression was used to assess risk factors. RESULTS 538 patients were available for analysis. The prevalence of persistent pain was 22% (CI: 18-25), and the prevalence of presumed neuropathic pain was 13% (CI: 10-16). Persistent pain was more frequent in fracture patients (29%) than in osteoarthritis patients (16%), while the prevalence of neuropathic pain was similar. Severe pain during the first postoperative week increased the risk of persistent pain. Risk also increased with hemiprosthesis (as compared to total prosthesis) in osteoarthritis patients, and with previous osteosynthesis and pain elsewhere in fracture patients. INTERPRETATION Persistent pain after shoulder replacement is a daily burden for many patients. Further studies should address patient and prosthesis selection, postoperative pain management, and follow-up of these patients.

Abstract
BACKGROUND AND PURPOSE Previously, implant survival of total shoulder prostheses was reported to be inferior to that of hemiprostheses. However, the use of total prostheses has increased in Norway due to reported good functional results. On this background, we wanted to study implant survival of 4 major shoulder prosthesis types in Norway between 1994 and 2012. PATIENTS AND METHODS The study population comprised 4,173 patients with shoulder replacements reported to the Norwegian Arthroplasty Register, including 2,447 hemiprostheses (HPs), 444 anatomic total prostheses (ATPs), 454 resurfacing prostheses (RPs), and 828 reversed total prostheses (RTPs). Three time periods were compared: 1994-1999, 2000-2005, and 2006-2012. Kaplan-Meier failure curves were used to compare implant failure rates for subgroups of patients, and adjusted risks of revision were calculated using Cox regression analysis. RESULTS For prostheses inserted from 2006 through 2012, the 5-year survival rates were 95% for HPs (as opposed to 94% in 1994-1999), 95% for ATPs (75% in 1994-1999), 87% for RPs (96% in 1994-1999), and 93% for RTPs (91% in 1994-1999). During the study period, the implant survival improved significantly for ATPs (p < 0.001). A tendency of better results with acute fracture and worse results in sequelae after previous fractures was seen in all time periods. INTERPRETATION The 5-year implant survival rates were good with all prosthesis types, and markedly improved for anatomic total prostheses in the last 2 study periods. The better functional results with total shoulder prostheses than with hemiprostheses support the trend towards increased use of total shoulder prostheses.

Abstract
BACKGROUND Implant migration, bone mineral density (BMD), length of glenohumeral offset (LGHO), and clinical results were compared for the Copeland (Biomet Inc, Warsaw, IN, USA) and the Global C.A.P. (DePuy Int, Warsaw, IN, USA) humeral head resurfacing implants (HHRIs). METHODS The study randomly allocated 32 patients (13 women), mean age 63 years (range, 39-82 years), with shoulder osteoarthritis to a Copeland (n = 14) or Global C.A.P. (n = 18) HHRI. Patients were monitored for 2 years with radiostereometry, dual-energy X-ray absorptiometry, Constant Shoulder Score (CSS), and the Western Ontario Osteoarthritis of the Shoulder Index (WOOS). LGHO was measured preoperatively and 6 months postoperatively. RESULTS At 2 years, total translation (TT) was 0.48 mm (standard deviation [SD], 0.21 mm) for the Copeland and 0.82 mm (SD, 0.46 mm) for the Global C.A.P. (P = .06). Five HHRI were revised, and in the interval before the last follow-up (revision or 2 years), TT of 0.58 mm (SD, 0.61 mm) for revised HHRI was higher (P = .02) than TT of 0.22 mm (SD, 0.17 mm) in nonrevised HHRI. A comparison of TT at the last follow-up (revision or 2 years) found no difference between the HHRIs (P = .12). Periprosthetic BMD decreased initially but increased continuously after 6 months for both HHRIs. At 2 years, BMD was 48% higher around the Copeland HHRI (P = .005). The mean difference in LGHO was significantly higher for the Copeland than for the Global C.A.P. HHRI (P = .02). Clinical results evaluated with CSS and WOOS improved over time for both implant groups (P < .01), with no differences between the groups. CONCLUSION Both implants had only little migration and good clinical results. Periprosthetic BMD and LGHO both increased for the Copeland HHRI more than for the Global C.A.P HHRI.

Abstract
PURPOSE The aim of this study was to conduct a randomised, clinical trial comparing stemmed hemiarthroplasty and resurfacing hemiarthroplasty in the treatment of glenohumeral osteoarthritis. METHODS A total of 40 shoulders (35 patients) were randomised to stemmed hemiarthroplasty or resurfacing hemiarthroplasty and evaluated three and 12 months postoperatively using the Constant-Murley score (CMS) and Western Ontario Osteoarthritis of the Shoulder (WOOS) index. RESULTS There were no statistically significant differences in age, gender or pre-operative scores except for WOOS at baseline. Two patients were lost to follow-up. Significant improvements in CMS and WOOS were observed at one year after both arthroplasty designs. At one year, the mean CMS was 48.9 (range 6-80) after resurfacing hemiarthroplasty and 59.1 (range 0-88) after stemmed hemiarthroplasty {mean difference 10.2 [95 % confidence interval (CI) -3.3 to 23.6], P = 0.14}. The mean WOOS was 59.2 (range 5.2-100.0) and 79.4 (range 12.8-98.6), respectively [mean difference 20.2 (95 % CI 3.4-36.9), P = 0.02]. No major complications occurred and there were no revisions. CONCLUSIONS The effects of resurfacing hemiarthroplasty tended to be inferior to those of stemmed hemiarthroplasty. It is unclear whether this reflects a real difference in effect or baseline differences due to the limited number of randomised patients. We suggest there is a need for a larger, more definitive trial.

Abstract
PURPOSE We used patient-reported outcome and risk of revision to compare hemiarthroplasty (HA) with total shoulder arthroplasty (TSA) and stemmed hemiarthroplasty (SHA) with resurfacing hemiarthroplasty (RHA) in patients with glenohumeral osteoarthritis. PATIENTS AND METHODS We included all patients reported to the Danish Shoulder Arthroplasty Registry (DSR) between January 2006 and December 2010. 1,209 arthroplasties in 1,109 patients were eligible. Western Ontario Osteoarthritis of the Shoulder index (WOOS) was used to evaluate patient-reported outcome 1 year postoperatively. For simplicity of presentation, the raw scores were converted to a percentage of the maximum score. Revision rates were calculated by checking reported revisions to the DSR until December 2011. WOOS and risk of revision were adjusted for age, sex, previous surgery, and type of osteoarthritis. RESULTS There were 113 TSAs and 1096 HAs (837 RHAs and 259 SHAs). Patients treated with TSA generally had a better WOOS, exceeding the predefined minimal clinically important difference, at 1 year (mean difference 10, p < 0.001). RHA had a better WOOS than SHA (mean difference 5, p = 0.02), but the difference did not exceed the minimal clinically important difference. There were no statistically significant differences in revision rate or in adjusted risk of revision between any of the groups. INTERPRETATION Our results are in accordance with the results from other national shoulder registries and the results published in systematic reviews favoring TSA in the treatment of glenohumeral osteoarthritis. Nonetheless, this registry study had certain limitations and the results should be interpreted carefully.
