Aims Few studies have compared survivorship of total shoulder arthroplasty (TSA) with hemiarthroplasty (HA). This observational study compared survivorship of TSA with HA while controlling for important covariables and accounting for death as a competing risk. Patients and Methods All patients who underwent shoulder arthroplasty in Ontario, Canada between April 2002 and March 2012 were identified using population-based health administrative data. We used the Fine–Gray sub-distribution hazard model to measure the association of arthroplasty type with time to revision surgery (accounting for death as a competing risk) controlling for age, gender, Charlson Comorbidity Index, income quintile, diagnosis, and surgeon factors. Results During the study period, 5777 patients underwent shoulder arthroplasty (4079 TSA, 70.6%; 1698 HA, 29.4%), 321 (5.6%) underwent revision, and 1090 (18.9%) died. TSA patients were older (TSA mean age 68.4 years (sd 10.2) vs HA mean age 66.5 years (sd 12.7); p = 0.001). The proportion of female patients was slightly lower in the TSA group (58.0% vs 58.4%). The adjusted association between surgery type and time to shoulder revision interacted significantly with patient age. Compared with TSA patients, revision was more common in the HA group (adjusted-health ratio (HR) 1.214, 95% confidence interval (CI) 0.96 to 1.53) but this did not reach statistical significance. Conclusion Although there was a trend towards higher revision risk in patients undergoing HA, we found no statistically significant difference in survivorship between patients undergoing TSA or HA.

Arthroplasty Revision

Background Total shoulder arthroplasty (TSA) has demonstrated good long-term survivorship but early implant failure can occur. This study identified factors associated with shoulder arthroplasty revision and constructed a risk score for revision surgery following shoulder arthroplasty. Methods A validated algorithm was used to identify all patients who underwent anatomic TSA between 2002 and 2012 using population-based data. Demographic variables included shoulder implant type, age and sex, Charlson comorbidity score, income quintile, diagnosis, and surgeon arthroplasty volume. The associations of covariates with time to revision were measured while treating death as a competing risk and were expressed in the Shoulder Arthroplasty Revision Risk Score (SARRS). Results During the study period, 4079 patients underwent TSA. Revision risk decreased in a nonlinear fashion as patients aged and in the absence of osteoarthritis with no influence from surgery type or other covariables. The SARRS ranged from −21 points (5-year revision risk 0.75%) to 30 points (risk 11.4%). Score discrimination was relatively weak 0.55 (95% confidence interval: 0.530.61) but calibration was very good with a test statistic of 5.77 ( df = 8, P = .762). Discussion The SARRS model accurately predicted the 5-year revision risk in patients undergoing TSA. Validation studies are required before this score can be used clinically to predict revision risk. Further study is needed to determine if the addition of detailed clinical data including functional outcome measures and the severity of glenohumeral arthrosis increases the model’s discrimination.

Background The purpose of this investigation was to compare rates of filled opioid prescriptions and prolonged opioid use in opioid naïve patients undergoing total shoulder arthroplasty (TSA) in inpatient versus outpatient settings. Methods A retrospective cohort study was conducted using a national insurance claims database. Inpatient and outpatient cohorts were created by identifying continuously enrolled, opioid naïve TSA patients. A greedy nearest-neighbor algorithm was used to match baseline demographic characteristics between cohorts with a 1:1 inpatient to outpatient ratio to compare the primary outcomes of filled opioid prescriptions and prolonged opioid use following surgery between cohorts. Results A total of 11,703 opioid naïve patients (mean age 72.5 ± 8.5 years, 54.5% female, 87.6% inpatient) were included for analysis. After propensity score matching (n = 1447 inpatients; n = 1447 outpatients), outpatient TSA patients were significantly more likely to fill an opioid prescription in the perioperative window compared to inpatients (82.9% versus 71.5%, p < 0.001). No significant differences in prolonged opioid use were detected (5.74% inpatient versus 6.77% outpatient; p = 0.25). Conclusions Outpatient TSA patients were more likely to fill opioid prescriptions compared to inpatient TSA patients. The quantity of opioids prescribed and rates of prolonged opioid use were similar between the cohorts. Level of evidence Therapeutic Level III.

Aims Scapular notching is thought to have an adverse effect on the outcome of reverse total shoulder arthroplasty (RTSA). However, the matter is still controversial. The aim of this study was to determine the clinical impact of scapular notching on outcomes after RTSA. Methods Three electronic databases (PubMed, Cochrane Database, and EMBASE) were searched for studies which evaluated the influence of scapular notching on clinical outcome after RTSA. The quality of each study was assessed. Functional outcome scores (the Constant-Murley scores (CMS), and the American Shoulder and Elbow Surgeons (ASES) scores), and postoperative range of movement (forward flexion (FF), abduction, and external rotation (ER)) were extracted and subjected to meta-analysis. Effect sizes were expressed as weighted mean differences (WMD). Results In all, 11 studies (two level III and nine level IV) were included in the meta-analysis. All analyzed variables indicated that scapular notching has a negative effect on the outcome of RTSA . Statistical significance was found for the CMS (WMD –3.11; 95% confidence interval (CI) –4.98 to –1.23), the ASES score (WMD –6.50; 95% CI –10.80 to –2.19), FF (WMD –6.3°; 95% CI –9.9° to –2.6°), and abduction (WMD –9.4°; 95% CI –17.8° to –1.0°), but not for ER (WMD –0.6°; 95% CI –3.7° to 2.5°). Conclusion The current literature suggests that patients with scapular notching after RTSA have significantly worse results when evaluated by the CMS, ASES score, and range of movement in flexion and abduction.

e16146 Background: A growing number of patients with colorectal cancer (CRC) have survived a previous cancer. Although little is known about their prognosis, this population is frequently excluded from clinical trials. We examined the impact of previous cancer on overall and cancer-specific survival in a population-based cohort of patients diagnosed with incident CRC. Methods: We identified patients aged ≥66 years and diagnosed with CRC between 2005-2015 in linked SEER-Medicare data. For patients with and without previous cancer, we estimated overall survival using Cox regression and cause-specific survival using competing risk regression, separately by CRC stage, while adjusting for numerous covariates and competing risk of death from previous cancer, other causes, or the incident CRC. Results: Of 112,769 CRC patients diagnosed with incident CRC, 15,935 (14.1%) had a previous cancer – most commonly prostate (32.9%) or breast (19.4%) cancer, with many 7505 (47.1%) diagnosed ≤5 years of CRC. For all CRC stages except IV in which there was no significant difference in survival, patients with previous cancer had modestly worse overall survival (hazard ratios from fully adjusted models range from 1.11-1.28 across stages; see Table). This survival disadvantage was driven by deaths due to previous cancer and other causes. Notably, most patients with previous cancer had improved CRC-specific survival. Conclusions: CRC patients who have survived a previous cancer have generally worse overall survival but superior CRC-specific survival. This evidence should be considered concurrently with concerns about trial generalizability, low accrual, and heterogeneity of participants when determining exclusion criteria. [Table: see text]

Mid Term Results

Aims The use and variety of stemless humeral components in anatomical total shoulder arthroplasty (TSA) have proliferated since their advent in 2004. Early outcomes are reassuring but independent mid-term results are scarce. This independent study reports a consecutive series of 143 Eclipse stemless shoulder prostheses with a minimum five-year (5 to 10) follow-up. Methods Outcomes of 143 procedures undertaken for all indications in 131 patients were reviewed, with subset analysis of those for osteoarthritis (OA) (n = 99). The primary outcome was the Oxford Shoulder Score (OSS) at a minimum of five years. Secondary outcomes were ranges of motion and radiological analysis of humeral radiolucency, rotator cuff failure, and glenoid loosening. Results Mean OSS at mean follow-up of 6.67 years (5.0 to 10.74) was 40.12 (9 to 48), with no statistically significant difference between those implanted for a non-OA indication and those for OA (p = 0.056) or time-dependent deterioration between two years and five years (p = 0.206). Ranges of motion significantly improved compared with preoperative findings and were maintained between two and five years with a mean external rotation of 38° (SD 18.1, 0 to 100) and forward elevation of 152° (SD 29.9, 90 to 180). Of those components with radiographs suitable for analysis (n = 83), 23 (28%) were found to have a least one humeral radiolucent line, which were predominantly incomplete, less than 2 mm, and in a single anatomical zone. No humeral components were loose. A radiolucent line was present around 22 (15%) of glenoid components, and 15 (10%) of components had failed. Rotator cuff failure was found in 21 (15%) components. The mean time to either glenoid or rotator cuff failure was greater than three years following implantation. Survivorship was 96.4% (95% CI 91.6 to 98.5, number at risk 128) at five years, and 94.3% (95% CI 88.2 to 97.3, number at risk 76) at seven years, both of which compare favourably with best results taken from available registries. Conclusion Functional and radiological outcomes of the Eclipse stemless TSA are excellent, with no loose humeral components at minimum five-year follow-up. The presence of radiolucent lines is of interest and requires long-term observation but does not impact on the clinical results. Of the eight revisions required, this was predominantly for glenoid and rotator cuff failure. Cite this article: Bone Joint J 2022;104-B(1):83–90.

Abstract Background: Reverse total shoulder arthroplasty (RSA) increases deltoid muscle fiber recruitment and tension to compensate for deficient rotator cuff activity; however, it is unclear whether the anterior or middle deltoid becomes dominant and how the muscle activation profile changes postoperatively. Using minimally invasive electromyography, this study evaluated the activity of the deltoid and surrounding muscles during shoulder motion to assess muscle activation changes post-RSA. Methods: In this observational study, we assessed change in preoperative to postoperative shoulder muscle activation in 10 patients over 6 months. Muscle activation was measured using 8 surface electrodes. Activation of the anterior, middle and posterior deltoid and surrounding muscles were recorded during shoulder abduction, flexion, external and internal rotation were quantified. One-way analysis of variance was used to identify significant differences in activation and time or speed. Least significant difference post hoc test was used to determine specific differences in muscle activation at subsequent time points. Results: RSA shoulders at 6 months postoperative showed a significant increase in activity of the middle deltoid predominantly. Middle deltoid activation increased during abduction (P < 0.001), flexion (P = 0.008), external (P < 0.001) and internal (P < 0.001) rotation. Conclusions: Our study demonstrates the middle deltoid predominates in rotator cuff function in RSA as defined by quantitative activation, significant involvement in all shoulder motions, and increased activation at subsequent times. These findings may help guide future RSA designs to optimize deltoid wrapping allowing for maximal strength and efficiency.

Background: The number of rotator cuff repairs (RCRs) is increasing each year. Total shoulder arthroplasty (TSA) is a successful treatment option for patients with glenohumeral osteoarthritis with a functioning rotator cuff. Purpose/Hypothesis: The purposes of this study were to report the outcomes of TSA in patients with ipsilateral RCR and determine whether patients with a history of ipsilateral RCR who subsequently underwent TSA had differences in outcomes compared with matched controls who underwent TSA with no history of RCR. We hypothesized that patients with prior RCR will have significant improvements in clinical outcome scores, with no difference in outcomes after TSA compared with those with no prior RCR. Study Design: Cohort study; Level of evidence, 3. Methods: Patients eligible for inclusion were those with a history of prior RCR who underwent TSA at a single institution with a minimum 2-year follow-up between 2000 and 2015. Outcomes for this group, including American Shoulder and Elbow Surgeons (ASES) scores, were reported and then compared with a matched control group of patients who underwent TSA with no history of prior RCR. Controls were matched based on age, sex, and preoperative ASES score. Results: Overall, 14 patients (64% males; mean ± SD age, 65.1 ± 11.1 years) underwent prior ipsilateral RCR before TSA. ASES scores significantly improved from 42.9 to 78.5 at 2 years and to 86.6 at 5 years. When compared with 42 matched control patients (matched 1:3) who underwent TSA with no history of RCR, there was no significant difference in ASES scores at 2 years (78.5 vs 85.3; P = .19) and 5 years (86.6 vs 90.9; P = .72) between the prior RCR and no RCR groups. Conclusion: TSA in patients with a history of prior ipsilateral RCR led to significant improvements in clinical outcomes. No difference in clinical outcomes at 2 or 5 years after TSA was found between patients with and without a history of prior ipsilateral RCR.

Abstract Background Compared with anatomic total shoulder arthroplasty (aTSA), reverse total shoulder arthroplasty (RTSA) is associated with lower preoperative and postoperative outcome scores and range of motion. It is unknown whether patients' preoperative expectations of surgery are lower in RTSA compared with aTSA. The purpose of this study was to assess preoperative patient expectations and postoperative outcomes in aTSA and RTSA. Methods A consecutive series of patients undergoing primary aTSA for diagnosis of osteoarthritis or primary RTSA for diagnosis of rotator cuff tear arthropathy were studied prospectively. Expectations were evaluated using the validated Hospital for Special Surgery's Shoulder Surgery Expectations Survey. Baseline demographics, comorbidities, and social factors were collected. Baseline and 2 years postoperative American Shoulder and Elbow Surgeons (ASES) score, visual analog scale pain, Single Assessment Number Evaluation (SANE), and patient satisfaction were obtained. Results There were 128 patients (64 aTSA and 64 RTSA). There was no significant difference in total preoperative expectations score between groups. On multivariate linear regression analysis, aTSA (p = 0.024) and younger age (p = 0.018) were associated with higher expectations for improved ability to exercise. Changes in preoperative to postoperative ASES (p = 0.004) and SANE (p = 0.001) scores were higher in the aTSA group. Total preoperative expectations score was not correlated with postoperative functional outcomes or satisfaction in either group. In the aTSA group, expectations for participation in exercise were positively correlated with changes in preoperative to postoperative ASES score (p = 0.01) and SANE score (p = 0.01). Conclusion Though patients undergoing primary aTSA demonstrated greater improvement in functional outcome than those undergoing primary RTSA, both groups reported similar aggregate preoperative expectations. Those undergoing aTSA had higher expectations for return to exercise which was positively correlated with postoperative functional outcomes. Level of Evidence Level II, prospective cohort study.

Background Finite element analysis has suggested that stemless implants may theoretically decrease stress shielding. The purpose of this study was to assess the radiographic proximal humeral bone adaptations seen following stemless anatomic total shoulder arthroplasty. Methods A retrospective review of 152 prospectively followed stemless total shoulder arthroplasty utilizing a single implant design was performed. Anteroposterior and lateral radiographs were reviewed at standard time points. Stress shielding was graded as mild, moderate, and severe. The effect of stress shielding on clinical and functional outcomes was assessed. Also, the influence of subscapularis management on the occurrence of stress shielding was determined. Results At 2 years postoperatively, stress shielding was noted in 61 (41%) shoulders. A total of 11 (7%) shoulders demonstrated severe stress shielding with 6 occurring along the medial calcar. There was one instance of greater tuberosity resorption. At the final follow-up, no humeral implants were radiographically loose or migrated. There was no statistically significant difference in clinical and functional outcomes between shoulders with and without stress shielding. Patients undergoing a lesser tuberosity osteotomy had lower rates of stress shielding, which was statistically significant ( p = 0.021) Discussion Stress shielding does occur at higher rates than anticipated following stemless total shoulder arthroplasty, but was not associated with implant migration or failure at 2 years follow-up. Level of evidence IV, Case series.
