Elective Total Shoulder Arthroplasty in Octogenarians: A Safe Procedure

Total shoulder arthroplasty in patients aged 80 years and older: a systematic review

BACKGROUND

Elderly patients and their surgeons may eschew shoulder arthroplasty due to concerns over patient safety and longevity. The purpose of this study was to review the current literature evaluating the clinical and radiographic outcomes of shoulder arthroplasty performed in patients 80 years and older.

METHODS

A literature search of the Embase, PubMed, Medline, and Cochrane databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies evaluating the outcomes of primary and revision anatomic (aTSA) and reverse (RSA) total shoulder arthroplasty in patients 80 years and older were included for analysis.

RESULTS

A total of 15 studies evaluating 1685 primary aTSAs, 1170 primary RSAs, 69 RSAs performed for fracture, and 45 revision RSAs were included for review. The postoperative active forward flexion and external rotation ranged from 138° to 150° and 45° to 48° after aTSA and from 83° to 139° and 16° to 47° after RSA, respectively. Postoperative visual analog scale pain scores ranged from 0 to 1.8 after aTSA and from 0 to 1.4 after RSA. Ninety-day mortality ranged from 0% to 3%, and perioperative complications ranged from 0% to 32%. Late complications ranged from 5.6% to 24% for aTSA patients and 3.5% to 29% for patients undergoing RSA for all indications. Common complications included glenoid loosening (0%-18%) and rotator cuff tear (5.6%-10%) after aTSA and scapular notching (0%-40%) and scapular fracture (4%-9.4%) after RSA. Reoperation rates ranged from 0% to 6% after aTSA and from 0% to 13% after RSA.

CONCLUSIONS

aTSA and RSA in this population are safe and effective, demonstrating low rates of perioperative mortality and reoperation, durability that exceeds patient longevity, satisfactory postoperative range of motion, and excellent pain relief. Late complication rates appear to be similar for aTSA and RSA.

Diabetes status and postoperative complications for patients receiving open rotator cuff repair

Background

Diabetic patients are known to have poor wound healing and worse outcomes following surgeries. The purpose of this study is to evaluate diabetes status and complications for patients receiving open rotator cuff repair.

Methods

Patients undergoing open rotator cuff repair from 2006 to 2018 were identified in a national database. Patients were stratified into 3 cohorts: no diabetes mellitus, non-insulin dependent diabetes mellitus (NIDDM), and insulin dependent diabetes mellitus (IDDM). Differences in demographics, comorbidities, and complications were assessed with the use of bivariate and multivariate analyses.

Results

Of 7678 total patients undergoing open rotator cuff repair, 6256 patients (81.5%) had no diabetes, 975 (12.7%) had NIDDM, and 447 (5.8%) had IDDM. Bivariate analyses revealed that IDDM patients had increased risk of mortality, extended length of stay, and readmission compared to non-diabetic patients (p < 0.05 for all). IDDM patients had higher risks of major complications and readmission relative to NIDDM patients (p < 0.05 for both). On multivariate analysis, there were no differences in any postoperative complications between the non-diabetic, NIDDM, and IDDM groups.

Discussion

Diabetes does not affect postoperative complications following open rotator cuff repairs. Physicians should be aware of this finding and counsel their patients appropriately.Level of Evidence: III.

Outcomes of anatomic and reverse total shoulder arthroplasty in patients over the age of 70: a systematic review

Background

Both anatomic total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) reliably improve pain and function for a variety of indications. However, there remain concerns about these procedures among elderly patients due to their general health, the potential for lesser functional gain, and the possible need for revision at an even older age. The purpose of this review is to compare the clinical outcomes, radiographic outcomes, and complications of ATSA and RTSA among patients older than 70 years.

Methods

A systematic review was performed using searches of PubMed, Embase, and Cochrane databases. The inclusion criteria were studies with patients older than 70 years who were treated with a primary ATSA or RTSA and clinical results reported at a minimum of 2 years. All indications for primary RTSA except for tumor were included. Outcomes of interest included patient-reported outcomes (PROs), range of motion, patient satisfaction, radiographic changes, complication and revision rates, and implant survival.

Results

A total of 24 studies met the inclusion criteria. At a mean follow-up of 3.4 years for ATSA and 3.1 years for RTSA, there were significant improvements in pain, range of motion, and PROs for both prostheses. Patients who underwent ATSA generally had better motion and functional outcomes compared to those who underwent RTSA, though these comparisons were made across different indications for arthroplasty. The satisfaction rate was 90.9% after ATSA and 90.8% after RTSA. Furthermore, 10.2% of ATSA patients and 9.9% of RTSA patients experienced a surgical complication, whereas 2.3% of ATSA and 2.2% of RTSA patients underwent a revision. Secondary rotator cuff tear was the most common complication after ATSA, occurring in 3.7% of patients, but only 1.1% of patients required revision surgery. Both ATSA and RTSA implant survivorship was reported to range from 93.1% to 98.9% at 5- and 8-year follow-up, respectively. Patient mortality was estimated to be 19.3% with a mean time to death of 6.1 years.

Conclusions

Elderly patients with primary osteoarthritis and an intact rotator cuff can have predictable pain relief, restoration of functional range of motion, and significant improvement in PROs after ATSA with low complication rates. Secondary rotator cuff failure and revision arthroplasty occur infrequently at early to mid-term follow-up. Although elderly patients who underwent ATSA generally had better functional outcomes compared to those who underwent RTSA for differing indications, patient satisfaction after both procedures were similar.

Reverse shoulder arthroplasty in patients 85 years and older is safe, effective, and durable

BACKGROUND

Reverse shoulder arthroplasty (RSA) was originally indicated for older adults, but outcomes in the oldest patients have not been studied. The purpose of this study was to report on patients aged ≥85 years undergoing RSA. We hypothesized that RSA would be safe, effective, and durable.

METHODS

Sixty-one RSAs were performed in 58 patients aged ≥85 years (16 patients aged ≥90 years); 40 RSAs were performed for arthritis with cuff deficiency, 14 were performed for proximal humeral fractures, and 7 were performed as revisions. Active range of motion and patient-reported outcomes, comprising the American Shoulder and Elbow Surgeons score, Simple Shoulder Test score, and visual analog scale pain score, were obtained preoperatively and at final follow-up. Hospital length of stay, discharge disposition, and complications were recorded. Kaplan-Meier survivorship was computed with revision surgery or death as an endpoint.

RESULTS

The mean age at RSA was 88.0 years. Mean forward elevation improved from 50.5° to 105.3°; abduction, from 48.7° to 96.1°; and external rotation, from 10.2° to 26.9° (P < .001 for all). Similarly, at a mean follow-up of 2.4 years, the visual analog scale pain score improved from 6.1 to 0.6; Simple Shoulder Test score, from 2.2 to 7.0; and American Shoulder and Elbow Surgeons score, from 33.6 to 78.2 (P < .001 for all). The mean length of stay was 3.6 days, and 15 patients were discharged home. Seven patients received a blood transfusion, and only 2 patients underwent a reoperation, neither of whom required explantation.

DISCUSSION AND CONCLUSION

Improvements in active range of motion and patient-reported outcomes in our patients were comparable to those observed in younger cohorts and exceeded published minimal clinically important differences for most patients undergoing RSA for cuff deficiency. Additionally, to date, the patients in our study who died had lived with their RSA for a mean of 3.4 years and living patients had lived with their RSA for a mean of 4.3 years. RSA in patients aged ≥85 years is safe, effective, and durable for their remaining life expectancy. This information may help counsel older patients who are considering RSA, electively or for fractures.

Thirty-day morbidity and mortality following primary total elbow arthroplasty in octogenarians

Background

Octogenarians are at an increased risk of morbidity and mortality following various orthopaedic procedures, but this has not been explored among total elbow arthroplasty (TEA) patients. Thus, this study analyzed whether octogenarians undergoing TEA are at an increased risk of postoperative complications relative to the younger geriatric population.

Methods

A national database was queried to identify TEA patients. Patients were stratified into an aged 65 to 79 cohort and an aged 80 to 89 cohort. Demographics, comorbidities, and complications were assessed, with the use of bivariate and multivariate analyzes.

Results

In total, 390 patients underwent TEA, with 289 (74.1%) between the ages of 65 to 79 and 101 (25.9%) between the ages of 80 to 89. On bivariate analyzes, patients aged 80 to 89 were more likely to undergo postoperative transfusion (p = 0.001) compared to those aged 65 to 79. Following adjustment on multivariate analyzes, the aged 80 to 89 cohort no longer had an increased risk of postoperative transfusion. There were no differences in mortality, readmission, and reoperation between the two groups.

Discussion

Age greater than 80 should not be used as an independent factor when evaluating whether a geriatric patient is an appropriate candidate for TEA.

Thirty-day morbidity and mortality following revision total shoulder arthroplasty in octogenarians

BACKGROUND

Octogenarians are at an increased risk of morbidity and mortality following various surgeries, but this has not yet been well explored in octogenarians undergoing revision total shoulder arthroplasty (RTSA). Thus, the purpose of this study was to analyze whether octogenarians undergoing RTSA are at an increased risk of 30-day postoperative complications, readmissions, and mortality relative to the younger geriatric population.

METHODS

Data of patients who underwent RTSA from 2013 to 2018 were obtained from a large de-identified database. Patients were divided into two cohorts: ages 65-79 and ages 80-89. Demographic data, comorbidities, and postoperative complications were collected and compared between the two cohorts. Bivariate and multivariate analyses were performed.

RESULTS

On bivariate analyses, patients aged 80-89 were more likely to develop pulmonary embolism (p = 0.014) and extended length of stay more than 3 days (p = 0.006) compared to the cohort aged 65-79. Following adjustment on multivariate analyses, 80-89 years old patients no longer had an increased likelihood of pulmonary embolism or extended length of stay compared to the 65-79 age group. Octogenarians were not found to have higher rates of 30-day readmissions (p = 0.782), mortality (p = 0.507), reoperation (p = 0.785), pneumonia (p = 0.417), urinary tract infection (p = 0.739), or sepsis (p = 0.464) compared to the cohort aged 65-79 following RTSA.

CONCLUSION

Age greater than 80 should not be used independently as a factor for evaluating whether a geriatric patient is a proper candidate for RTSA.

Conclusion

Clinical outcomes of anatomic total shoulder arthroplasty for primary shoulder osteoarthritis did not differ between elderly and younger Japanese patients

Background

Few studies on the outcomes of anatomic total shoulder arthroplasty (aTSA) in Asian populations have been reported. In addition, approximately one-third of primary aTSA were performed for patients 80 years or older in Japan, but the indication of aTSA for the primary shoulder osteoarthritis in the elderly population remained unclear. The purposes of this study were (1) to investigate clinical outcomes of aTSA in Japanese patients with primary glenohumeral osteoarthritis and (2) to compare clinical outcomes between patients 80 years or older and 70 years or younger. We hypothesized that aTSA would yield favorable outcomes in Japanese patients and that the outcomes of aTSA in patients 80 years or older would be comparable to those 70 years or younger.

Methods

Patient records were retrospectively reviewed to collect patients who underwent aTSA for glenohumeral osteoarthritis between August 2011 and September 2017. The inclusion criterion of this study was aTSA performed for glenohumeral osteoarthritis. Exclusion criteria were as follows: (1) secondary osteoarthritis, (2) revision surgery, and (3) < 24-month follow-up. Range of motion (ROM) and Constant score were evaluated, and complications were investigated. Rotator cuff integrity was assessed by ultrasonography. We compared the outcomes between patients 80 years or older and 70 years or younger.

Results

Seventy-seven shoulders (72 patients) met the study criteria. There were 14 men and 58 women with a mean age of 75 years (range, 57-93 years) at the time of surgery. The mean follow-up was 40 months (range, 24-84 months). The Constant score significantly improved from preoperative 54 (range, 35-78) to postoperative 89 (range 69-100, P = .03). Range of motion also showed significant improvement after surgery: flexion, 90° (range, 60°-130°) to 140° (range, 90°-170°); external rotation at the side, from 7° (range, -10 to 60°) to 40° (range, 5°-70°); internal rotation, from buttock (range, buttock-L3) to L2 level (range, buttock-T8) (P <.001 for all). Postoperative subscapularis tendon tears were detected in 3 shoulders (5%). Complications other than rotator cuff tears were observed in 5 shoulders (6%). Postoperative Constant score and ROM significantly improved in both elderly and younger patients without significant differences.

Conclusion

The clinical outcomes after aTSA in the Japanese population demonstrated significant improvements in ROM and Constant score with a low complication rate in the mid-term follow-up. aTSA should be indicated even in elderly patients because they also demonstrated comparable outcomes to younger patients.

Increased severity of anemia is associated with postoperative complications following primary total shoulder arthroplasty

BACKGROUND

Anemia has been demonstrated as a modifiable risk factor for postoperative complications following various types of primary and revision total joint arthroplasties. However, at present, we are not aware of any studies assessing postoperative complications following total shoulder arthroplasty (TSA) in patients with varying severity of anemia. The purpose of this study was to determine the influence of preoperative anemia severity on 30-day postoperative complications following primary TSA.

METHODS

Adult patients undergoing primary TSA from 2012 to 2018 were identified in the National Surgical Quality Improvement Program database. Patients undergoing TSA were substratified into 3 cohorts: nonanemia (hematocrit >36% for women, >39% for men), mild anemia (hematocrit 33%-36% for women, 33%-39% for men), and moderate to severe anemia (hematocrit <33% for both women and men), based on World Health Organization definitions of anemia. In this analysis, 30-day wound, cardiac, pulmonary, renal, and thromboembolic complications, as well as sepsis, mortality, postoperative transfusion, extended length of stay, and reoperation were assessed. Bivariate analyses, including χ² and analysis of variance, and multivariable logistical regression were performed.

RESULTS

Of 13,921 total patients undergoing TSA, 11,330 patients (81.4%) did not have anemia, 1934 (13.9%) had mild anemia, and 657 (4.7%) had moderate to severe anemia. Following adjustment, patients with mild anemia were more likely to have a postoperative blood transfusion (odds ratio [OR] 4.7, P < .001), extended length of stay (OR 1.7, P = .002), and reoperation (OR 1.5, P = .028). Patients with moderate to severe anemia were at increased risk of cardiac complications (OR 3.0, P = .012), pulmonary complications (OR 2.2, P = .015), postoperative blood transfusion (OR 23.8, P < .001), extended length of stay (OR 6.6, P < .001), reoperation (OR 2.2, P = .003), and death (OR 3.8, P = .034).

CONCLUSION

From mild anemia to moderate to severe anemia, there was a stepwise and approximately 2-fold increase in the odds of postoperative complications for patients undergoing primary TSA. Patients with moderate to severe anemia should be medically optimized before they undergo TSA.

Short-Term Outcomes After Total Shoulder Arthroplasty in Octogenarians: A Matched Analysis

Introduction

Studies have shown that the use of total shoulder arthroplasty is increasing every year in the United Stated at a rate higher than that of total hip or total knee arthroplasty. As the population of the United States continues to age, it is becoming more important for surgeons to understand the true impact of age on outcomes and complications following procedures such a total shoulder arthroplasty. The purpose of this study was to determine if octogenarians have poorer outcomes after total shoulder arthroplasty compared to a younger, matched control group.

Methods

Data was obtained through the American College of Surgeons National Surgical Quality Improvement Program database (ACS NSQIP). Patients who had undergone total shoulder arthroplasty were identified by Current Procedural Terminology code (23472). Indication for arthroplasty was determined by ICD9/10 code (osteoarthritis, fracture, other). Each octogenarian was matched 1:1 to a non-octogenarian based on sex, BMI, ASA class, medical comorbidities, functional status, and surgical indication for arthroplasty by propensity scoring. A subgroup analysis was performed to compare outcomes between only those patients who underwent TSA for osteoarthritis.Outcomes of interest were assessed between the two groups for statistical significance using a chi-squared test or fisher exact test for expected values of less than 5. Statistical significance was set at p<0.05.

Results

After matching, octogenarians were found to be at higher risk of readmission (4.7% vs. 3.3%, p=0.046), non-home discharge (27.1% vs. 9.4%, p<0.001), and overall surgical (4.4% vs. 2.5%, p=0.006) and medical complications (3.7% vs. 2.4%, p=0.039). In the setting of TSA for osteoarthritis only, however, octogenarians were only at higher risk for non-home discharge (22.4% vs. 7.5%, p<0.001).

Conclusions

Octogenarians are at higher risk of some complications following total shoulder arthroplasty but fewer than has been previously reported, particularly in the setting of arthroplasty for the treatment of arthritis.

Pre-operative factors affecting the indications for anatomical and reverse total shoulder arthroplasty in primary osteoarthritis and outcome comparison in patients aged seventy years and older

BACKGROUND

We evaluated the pre-operative factors affecting anatomical and reverse total shoulder arthroplasty (TSA and RTSA) indications in primary osteoarthritis and compared outcomes in patients aged 70 years and older.

METHODS

Fifty-eight patients received a TSA with an all-polyethylene glenoid component (APGC) or an RTSA with/without glenoid lateralization and the same curved short-stem humeral component. Active anterior and lateral elevation (AAE, ALE), internal and external rotation (IR, ER), pain, and the Constant-Murley score (CS) were recorded pre and post-operatively. Pre-operative rotator cuff (RC) fatty infiltration (FI) and modified Walch glenoid morphology were assessed. Humeral and glenoid component radiological outcomes were recorded.

RESULTS

RTSA were older than TSA patients (p = 0.006), had lower pre-operative AAE (p < 0.001), ALE (p < 0.001), IR (p = 0.002), pain (p = 0.008) and CS (p < 0.001), and greater supraspinatus FI (p < 0.001). At a mean of 28.8 months, both implants yielded significantly different post-operative scores and similar complication rates. Both groups achieved similar post-operative AAE, ER, and IR; ALE was higher in TSA (p = 0.006); and AAE and ALE delta scores were higher in RTSA (p = 0.045 and p = 0.033, respectively). Radiolucent line rates were higher around the TSA APGC than the RTSA baseplate (p = 0.001). High-grade RC FI adversely affected mobility improvement. Humeral cortical thinning was significantly higher in TSA (p = 0.001).

CONCLUSION

RTSA patients were older, had poorer pre-operative active mobility, and had greater RC FI than TSA. Both devices provided good mid-term clinical and ROM improvement.

Unlike Native Hip Fractures, Delay to Periprosthetic Hip Fracture Stabilization Does Not Significantly Affect Most Short-Term Perioperative Outcomes

BACKGROUND

The incidence of periprosthetic hip fractures is increasing due to higher numbers of total hip arthroplasties being performed. Unlike native hip fractures, the effect of time to surgery of periprosthetic hip fractures is not well established. This study evaluates the effect of time to surgery on perioperative complications for patients with periprosthetic hip fractures.

METHODS

Patients who underwent surgery for periprosthetic hip fracture were identified in the 2005-2016 National Surgical Quality Improvement Program database and stratified into 2 groups: <2 and ≥2 days from hospital admission to surgery. Multivariate regressions were used to compare risk for perioperative complications between the 2 groups. Independent risk factors for postoperative serious adverse events were characterized.

RESULTS

In total, 409 (<2 days from admission to surgery) and 272 (≥2 days from admission to surgery) patients were identified. Multivariate analysis revealed only higher risk of extended postoperative stay for patients who had delays of ≥2 days to surgery compared to those who had <2 days from admission to surgery. Independent risk factors for serious adverse events included increasing age, dependent preoperative functional status, and preoperative congestive heart failure, but not time to surgery.

CONCLUSION

Unlike for native hip fractures, time to surgery for periprosthetic hip fractures does not appear to affect most 30-day perioperative complications. However, it is worth noting that this study was unable to control for all potential confounders and therefore the results may not be generalizable to all types of periprosthetic hip fractures.
