Clinical and financial outcomes of per-oral endoscopic myotomy compared to laparoscopic heller myotomy for treatment of achalasia.

BACKGROUND: Previous studies analyzing short-term outcomes for per-oral endoscopic myotomy (POEM) have shown excellent clinical response rates and shorter operative times compared to laparoscopic Heller myotomy (LHM). Despite this, many payors have been slow to recognize POEM as a valid treatment option. Furthermore, comparative studies analyzing long-term outcomes are limited. This study compares perioperative and long-term outcomes, cost-effectiveness, and reimbursement for POEM and LHM at a single institution. METHODS: Adult patients who underwent POEM or LHM between 2014 and 2021 and had complete preoperative data with at least one complete follow up, were retrospectively analyzed. Demographic data, success rate, operative time, myotomy length, length of stay, pre- and postoperative symptom scores, anti-reflux medication use, cost and reimbursement were compared. RESULTS: 58 patients met inclusion with 25 undergoing LHM and 33 undergoing POEM. There were no significant differences in preoperative characteristics. Treatment success (Eckardt ≤ 3) for POEM and LHM was achieved by 88% and 76% of patients, respectively (p = 0.302). POEM patients had a shorter median operative time (106 min. vs. 145 min., p = 0.003) and longer median myotomy length (11 cm vs. 8 cm, p < 0.001). All LHM patients had a length of stay (LOS) ≥ 1 day vs. 51.5% for POEM patients (p < 0.001). Both groups showed improvements in dysphagia, heartburn, regurgitation, Eckardt score, GERD HRQL, RSI, and anti-reflux medication use. The improvement in dysphagia score was greater in patients undergoing POEM (2.30 vs 1.12, p = 0.003). Median hospital reimbursement was dramatically less for POEM ($3,658 vs. $14,152, p = 0.002), despite median hospital costs being significantly lower compared to LHM ($2,420 vs. $3,132, p = 0.029). RESULTS: POEM is associated with a shorter operative time and LOS, longer myotomy length, and greater resolution of dysphagia compared to LHM. POEM costs are significantly less than LHM but is poorly reimbursed.

Examining emergency department utilization in the post-foregut surgery patient.

BACKGROUND: The purpose of this study was to examine emergency department (ED) utilization following minimally invasive foregut surgery and determine its impact on costs. Furthermore, we sought to determine their relationship to the index procedure, whether they are preventable, and describe strategies for decreasing unnecessary ED visits. METHODS: A retrospective review was conducted for all patients undergoing foregut procedures from January 2018 through June 2019. ED utilization was examined from 0 to 90 days. The proportion of visits related to surgery, preventable visits, and median ED costs were compared between visits occurring 0-30 days (early) versus 31-90 days (delayed) postoperatively as well as occurring from 8 am to 5 pm versus 5 pm to 8 am. RESULTS: Of 458 patients who underwent foregut surgery, 72.5% were female and the mean age was 60 years old. 92 patients (20%) presented to the ED within 90 days. Of these, 59 patients (64.1%) presented to the ED early versus 33 patients (35.9%) delayed. 56.5% of ED visits occurred during clinic hours. 56 (60.9%) ED visits were related to the procedure and 20 (35.7%) were preventable. The median ED return cost was $970. Early ED visits were significantly more likely to be related to surgery (72.9% vs 39.4%, p = 0.0016). There was no significant difference in the proportion of visits that were preventable (32.6% vs 46.2%, p = 0.3755) and ED return cost did not vary significantly ($995 vs $965, p = 0.43) between early and delayed visits. CONCLUSIONS: ED visits are common after foregut surgery and represent a financial burden on healthcare. Most visits occur early and are more likely to be related to surgery. Importantly, more than one-third of ED visits related to surgery were preventable and most occurred during clinic hours on weekdays. Providers should consider implementation of strategies to improve outpatient utilization and decrease unnecessary ED visits.

Primary Monoblock Inset Reverse Shoulder Arthroplasty Resulted in Decreased Pain and Improved Function.

BACKGROUND: The first-generation, lateral-center-of-rotation reverse shoulder arthroplasty (RSA) modular design has demonstrated durable early-, mid-, and long-term outcomes. The second-generation monoblock implant shares a similar design but eliminates the modular junction and facilitates inset placement within the metaphysis to avoid humeral-sided junctional failures and facilitate metaphyseal press-fit. However, no paper has specifically examined the radiographic findings and improvements in pain and function after the use of this next generation design. QUESTIONS/PURPOSES: (1) After second-generation, lateral-center-of-rotation monoblock RSA, what are the improvements in shoulder scores, general health scores, and ROM at a minimum of 2 years of followup? (2) Are the differences in shoulder scores, health scores, and ROM associated with fixation (cemented versus cementless components)? (3) How frequently do complications occur (defined as humeral loosening, dislocation, baseplate failure, scapular notching, acromial fractures, and revision surgery) after inset monoblock RSA? METHODS: We retrospectively studied patients undergoing primary RSA between 2010 and 2015 with preoperative data and a minimum of 2 years of clinical followup. Of the 329 primary RSA performed during this period, 125 were excluded based on the use of a different generation humeral stem of the same design, three based on need for a nickel-free implant, and 39 due to a lack of preoperative shoulder scores. Of the remaining 162 patients, 137 patients (85%) met the inclusion criteria with a mean age of 74 years (range, 46-90 years). The predominant indications were osteoarthritis with a massive rotator cuff tear (74%) and fracture sequelae (16%). During the study, humeral implants were typically inserted using an uncemented press-fit technique (85%), with only 21 patients requiring a cemented humeral stem. The mean clinical and radiographic followup period was 37 months (range, 24-82 months). Patient-reported outcome measures (PROMs) including the Simple Shoulder Test, American Shoulder and Elbow Surgeons Total, VAS for pain, SF-12, Single Assessment Numeric Evaluation, and measured active motion (forward elevation and external and internal rotation) were recorded at pre- and postoperative intervals. Postoperative radiographs were evaluated for baseplate failure, glenoid and humeral loosening, scapular notching, and acromion fractures. Complications were recorded in the longitudinally maintained institutional repository. RESULTS: At the most recent followup examination, there were improvements in measured motion, general health outcomes, and all PROMs. There were no differences between the cemented and press-fit techniques. Complications observed included 17 of 137 patients (12%) with scapular notching, six postoperative acromion fractures (4%), and two revision procedures (1%). No patients experienced gross humeral loosening or baseplate failure. CONCLUSIONS: Primary RSA using a second-generation monoblock inset humeral component resulted in improvements in pain and functional outcomes as well as low rates of acromion fractures, humeral radiolucency, and complications. Future studies are needed to provide a more definitive analysis on the use of an uncemented technique for humeral stem fixation and the effect of an inset stem on postoperative acromion fractures. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Management of Three- and Four-Part Proximal Humerus Fractures.

The management of three- and four-part proximal humerus fractures remains controversial because the literature has supported all forms of management, including nonsurgical management, open reduction and internal fixation (ORIF), and shoulder arthroplasty. Specific patient factors ultimately influence the decision of which treatment best fits the patient and the fracture. Surgeons should understand the rationale for nonsurgical and surgical management of these fractures, including ORIF and reverse shoulder arthroplasty.

Value comparison of humeral component press-fit and cemented techniques in reverse shoulder arthroplasty.

BACKGROUND: Press-fit humeral fixation for reverse shoulder arthroplasty (RSA) has been shown to have loosening rates and outcomes similar to a cemented technique; however, increased value has not been reported. The purpose of this study was to determine whether the press-fit technique could improve the value of RSA using the procedure value index (PVI). METHODS: Primary RSA patients with complete hospitalization cost data, preoperative and minimum 2-year postoperative Simple Shoulder Test (SST) scores, and postoperative satisfaction were included. The PVI was calculated as improvement in the SST score (in units of minimal clinically important difference) divided by total cost and normalized. Itemized cost data were obtained from hospital financial records and categorized. Radiographic complications, infections, and revisions were noted. Comparisons were made between the press-fit and cemented RSA cohorts. RESULTS: A total of 176 primary RSA patients (83 cemented and 93 press fit) met the inclusion criteria (mean follow-up period, 44.6 months). Surgical indications (except failed rotator cuff repair), baseline SST scores, and demographic characteristics were similar. The calculated minimal clinically important difference for the SST score was 3.98. The average PVI was significantly greater in the press-fit cohort (1.51 vs 1.03, P < .001), representing a 47% difference. SST score improvement was not significantly different (P = .23). However, total hospitalization costs were significantly lower for the press-fit cohort ($10,048.89 vs $13,601.14; P < .001). CONCLUSION: Use of a press-fit technique led to a 47% increase in value over a cemented technique. This appeared to be a function of decreased total costs rather than increased outcome scores.

Lesser tuberosity osteotomy in total shoulder arthroplasty: impact of radiographic healing on outcomes.

BACKGROUND: Lesser tuberosity osteotomy (LTO) has gained popularity in anatomic total shoulder arthroplasty (TSA); however, healing rates have not been universally high. This study examined differences in outcomes based on variations in LTO healing. METHODS: A retrospective review identified primary TSA patients with 2-year minimum follow-up treated with a LTO. Postoperative radiographs classified LTO healing as "bony union," "nondisplaced nonunion," "displaced nonunion," and "not seen," creating 4 cohorts. Comparisons were made among patient-reported outcome measures (PROMs), motion, and radiographic evidence of component loosening. RESULTS: The study cohort consisted of 189 patients who met inclusion criteria, with an average age of 69.5 years (range, 32-89 years) and follow-up of 50 months (range, 24-95 months). There were 143 patients with union, 16 with nondisplaced nonunion, 14 with displaced nonunion, and 16 not seen. There were no differences in preoperative comparisons. All cohorts demonstrated significant improvements in PROMs and ranges of motion; however, the displaced nonunion cohort had no improvement in Single Assessment Numeric Evaluation (0.114) or internal rotation (P = .279). Patients with displaced nonunion had lower postoperative functional scores (Simple Shoulder Test and American Shoulder and Elbow Surgeons scores; P < .01), and higher pain scores (visual analog scale for pain; P < .01). However, 85.7% of patients reported they would have the same procedure again. Simple Shoulder Test (2.5) and American Shoulder and Elbow Surgeons score (37.5) improvements exceeded minimal clinically important difference thresholds for TSA. A higher rate of glenoid gross loosening was present in the displaced nonunion cohort (3 patients [21.4%]; P < .01). There were no cases of loose humeral stems. CONCLUSION: Patients with a displaced nonunion LTO site have lower functional scores and higher pain scores but still achieve substantial clinical improvement and high satisfaction rates.

Outcomes of anatomic total shoulder arthroplasty in patients with excessive glenoid retroversion: a case-control study.

BACKGROUND: Ideal management of severe glenoid retroversion during anatomic total shoulder arthroplasty (TSA) remains controversial, as previous reports have suggested that severe retroversion may negatively impact clinical outcomes. The purpose of this study was to evaluate the impact of severe glenoid retroversion on clinical and radiographic TSA outcomes using a standard glenoid component, as well as to compare outcomes among patients with less severe retroversion. METHODS: A case-control study was performed comparing 40 patients treated with TSA with more than 20° of glenoid retroversion preoperatively (average follow-up, 53 months) vs. a matched cohort of 80 patients with less than 20° of retroversion (average follow-up, 49 months). In all patients, the surgical technique, implant design, and postoperative rehabilitation protocol were identical. Patients were matched based on sex, age, indication, and prosthetic size. Comparisons were made regarding patient-reported outcome measures (PROMs), motion, postoperative radiographic loosening, and the presence of medial calcar resorption. RESULTS: Preoperatively, both groups demonstrated similar PROMs and measured motion, except for preoperative Single Assessment Numeric Evaluation scores and American Shoulder and Elbow Surgeons total scores, which were higher for the severe retroversion group (44.4 vs. 31.3 [P = .012] and 34.9 vs. 29.4 [P = .048], respectively). Postoperative PROMs and motion were also similar between the 2 cohorts. No significant differences were observed for postoperative radiographic findings. Medial calcar resorption was identified in 74 patients (61.7%). Calcar resorption and individual resorption grades were not found to differ significantly. CONCLUSION: At midterm follow-up, preoperative severe glenoid retroversion does not appear to influence clinical or radiographic outcomes of TSA using a standard glenoid component.

Predicting outstanding results after reverse shoulder arthroplasty using percentage of maximal outcome improvement.

BACKGROUND: The purpose of this study was to determine whether thresholds regarding the percentage of maximal improvement in the Simple Shoulder Test (SST) score and American Shoulder and Elbow Surgeons (ASES) score exist that predict excellent patient satisfaction after reverse shoulder arthroplasty (RSA). METHODS: Patients undergoing RSA with a single implant system were evaluated preoperatively and at a minimum 2-year follow-up. Receiver operating characteristic curve analysis determined thresholds to predict excellent patient satisfaction by evaluating the percentage of maximal improvement for SST and ASES scores. Preoperative factors were analyzed as independent predictors for achieving SST and ASES score thresholds. RESULTS: There were 198 (SST score) and 196 (ASES score) patients who met inclusion criteria. For SST and ASES scores, receiver operating characteristic curve analysis identified 61.3% (P < .001) and 68.2% (P < .001) maximal improvement as the threshold for maximal predictability of excellent satisfaction, respectively. Significant positive correlation between the percentage of maximum score achieved and excellent patient satisfaction for both groups was found (r = 0.440 [P < .001] for SST score; r = 0.417 [P < .001] for ASES score). Surgery on the dominant hand, greater baseline visual analog scale pain score, and cuff arthropathy were independent predictors for achieving the SST and ASES score threshold. CONCLUSION: Thresholds for the achievement of excellent satisfaction after RSA were 61.3% of maximal SST score improvement and 68.3% of maximal ASES score improvement. Independent predictors of achieving these thresholds were dominant-sided surgery and higher baseline visual analog scale pain scores for the SST score and rotator cuff arthropathy for the ASES score.

Medial calcar bone resorption after anatomic total shoulder arthroplasty: does it affect outcomes?

BACKGROUND: The incidence of medial calcar resorption has been shown to be common after uncemented total shoulder arthroplasty (TSA). With etiologies including stress shielding, debris-induced osteolysis, and infection, the clinical impact of medial calcar resorption has not been specifically examined. The purpose of this study was to determine whether resorption is associated with inferior outcomes or higher rates of radiographic loosening in TSA patients. METHODS: We conducted a retrospective review of TSA patients with minimum 2-year clinical follow-up. Patient-reported and functional outcome measures were recorded preoperatively and postoperatively. Postoperative radiographs were evaluated for glenoid and humeral component loosening. A new calcar resorption grading system was introduced to quantify the degree of resorption and assess the progression. RESULTS: A total of 171 patients met the inclusion criteria, with average clinical and radiographic follow-up periods of 50 and 46 months, respectively. Calcar resorption was identified in 110 patients (64.3%). No significant overall differences were observed between the patients with and without calcar resorption. Subgroup analysis showed that patients with grade 3 resorption had a higher incidence of glenoid radiolucencies (50%, P = .001) and patients with a progression from grade 1 to grade 3 had higher incidences of glenoid (50%, P = .003) and humeral (9%, P = .039) radiolucencies. CONCLUSION: Medial calcar resorption following TSA with a standard-length press-fit humeral component is common. Overall, no differences in patient-reported outcome measures or radiographic loosening were found compared with patients without calcar resorption. However, grade 3 calcar resorption and more dramatic progression of resorption should raise the suspicion of prosthetic loosening.

The procedure value index: a new method for quantifying value in shoulder arthroplasty.

BACKGROUND: The purpose of this study was to introduce the procedure value index (PVI) and apply this value instrument to shoulder arthroplasty. The PVI uses the value equation in units of minimal clinically important difference (MCID) to provide an objective system of quantifying value-driven care. Secondarily, we describe the PVI for both primary anatomic total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA) to highlight value differences between these patient populations. METHODS: Patients undergoing primary shoulder arthroplasty with minimum 2-year follow-up were identified retrospectively. MCIDs were determined for the Simple Shoulder Test (SST) score, American Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) score for pain, and Single Assessment Numeric Evaluation (SANE) score. Cost data were reported as total hospitalization costs, total charges, and total reimbursements. The PVI was calculated as the ratio of outcome improvement in units of MCID over the cost of care. Mean PVIs for TSA and RSA were compared. RESULTS: Five hundred thirty-four patients met the inclusion criteria. MCIDs for the SST, ASES, VAS pain, and SANE scores were 3.61, 29.49, 3.28, and 37.05, respectively. With the exception of the ASES score, improvements in units of MCID were not different between TSA and RSA. However, total hospitalization costs and charges were significantly higher for RSA (P < .001). PVIs based on total hospitalization costs and total charges for the SST, ASES, and VAS pain scores were significantly greater for TSA (P < .05). No other PVI was significantly different. CONCLUSIONS: The PVI was greater for TSA when total hospitalization costs and total charges were considered. The PVI helps highlight value differences in shoulder arthroplasty.

Predicting outstanding results after anatomic total shoulder arthroplasty using percentage of maximal outcome improvement.

BACKGROUND: The purpose of this study was to determine whether thresholds in the percentage of maximal improvement in the Simple Shoulder Test (SST) or American Shoulder and Elbow Surgeons (ASES) score exist for predicting "excellent" patient satisfaction after total shoulder arthroplasty (TSA). METHODS: A retrospective query identified patients who underwent TSA with a minimum of 2 years' follow-up. Preoperative and postoperative SST and ASES scores and postoperative patient satisfaction were recorded. Receiver operating characteristic curve analyses were performed to determine thresholds in the percentage of maximal improvement in the SST and ASES scores that predict excellent satisfaction. Univariate and multivariate analyses determined preoperative factors that predicted achievement of these thresholds. RESULTS: A total of 301 and 319 patients had at least 2 years' follow-up for the SST score and ASES score, respectively. We determined 72.1% of maximal improvement in the SST score to be the threshold for excellent satisfaction (area under the curve, 0.777; 95% confidence interval, 0.712-0.841; P < .001). We determined 75.6% of maximal improvement in the ASES score to be the threshold for excellent satisfaction (area under the curve, 0.799; 95% confidence interval, 0.743-0.856; P < .001). Both groups showed significant positive correlations between percentage of maximal score achieved and excellent satisfaction (r = 0.396 for SST score [P < .001] and r = 0.325 for ASES score [P < .001]). Younger age was the only independent predictor for achieving the SST score threshold. No independent predictors existed for the ASES score threshold. CONCLUSION: Achievement of 72.1% of maximal SST score improvement and achievement of 75.6% of maximal ASES score improvement represent thresholds for achievement of excellent satisfaction after TSA. Most preoperative factors did not have an impact on the likelihood of achieving these thresholds.

Midterm results of anatomic total shoulder arthroplasty with a third-generation implant.

BACKGROUND: Anatomic total shoulder arthroplasty (TSA) provides reliable, reproducible, and durable results; however, outcomes of many modern TSA systems are lacking. The present study reports early to midterm results of a third-generation TSA system using a traditional-length press-fit humeral stem and cemented glenoid. METHODS: A retrospective review was conducted of TSA patients with minimum 2-year clinical follow-up. Patient-reported outcome measures, including Simple Shoulder Test, American Shoulder and Elbow Surgeons Total, visual analog scale for pain, 12-Item Short Form Health Survey, and Single Assessment Numeric Evaluation, as well as measured active motion (forward elevation, external and internal rotation), were recorded at preoperative and postoperative intervals. Preoperative midglenoid axial computed tomography scans were used to evaluate eccentric glenoid wear, humeral head subluxation, and glenoid version. Most recent postoperative radiographs were used to evaluate glenoid loosening, humeral loosening, lesser tuberosity union, and medial calcar resorption. Patient satisfaction at final follow-up was reported as excellent, good, satisfied, or unsatisfied. RESULTS: There were 267 patients who met inclusion criteria, with a mean age of 70.9 years and mean clinical follow-up of 47 months. Average glenoid retroversion was 9.7°, and 27% had eccentric glenoid wear. At final follow-up, measured motion and nearly all patient-reported outcome measures showed significant improvements, with 75.6% of patients rating their satisfaction as excellent. No patient was considered "at risk" for humeral stem loosening. Glenoid radiolucencies were seen in 13.5% of shoulders (7 gross loosening). Five patients were revised to reverse TSA. CONCLUSION: TSA using a third-generation traditional-length press-fit stem and cemented glenoid provides excellent early to midterm outcomes with low rates of loosening and high rates of excellent satisfaction.

Loss of Functional Internal Rotation Following Various Combinations of Bilateral Shoulder Arthroplasty.

BACKGROUND: Limited internal rotation (IR) remains a concern for activities of daily living (ADLs) following bilateral shoulder arthroplasty (BSA). The purpose of this study was to evaluate the loss of the ability to perform functional IR tasks following BSA using various combinations of anatomic (TSA) and reverse (RSA) shoulder arthroplasty. METHODS: A retrospective review of an institutional shoulder-surgery database was conducted for patients who underwent BSA with any combination of TSA or RSA with at least a 2-year follow-up. IR range of motion (ROM) and individual American Shoulder and Elbow Surgeons (ASES) score and Simple Shoulder Test (SST) questions specific to IR were used to assess a patient's ability to perform IR tasks with at least one of their shoulders. RESULTS: Seventy-three patients met the inclusion criteria (47 TSA/TSA, 17 RSA/RSA, and 9 TSA/RSA). Average age at surgery was 72.1 years. Average follow-up was 51.4 months. Loss of ability to wash one's back was observed in 30.4% TSA/TSA, 33.3% TSA/RSA, and 52.9% RSA/RSA. Loss of ability to tuck in a shirt was observed in 10.6% TSA/TSA, 11.1% TSA/RSA, and 29.4% RSA/RSA. Loss of ability to manage toileting was observed in no TSA/TSA or TSA/RSA, but in 11.8% RSA/RSA. For each of the tasks, there were no significant differences in the ability to perform the task among the groups (p>0.05). Post-operative IR ROM for TSA/TSA was superior to those for TSA/RSA and RSA/RSA (p<0.01). IR ROM efficacies for both RSA/RSA and TSA/RSA were inferior to that for TSA/TSA (p<0.05). CONCLUSION: Bilateral RSA patients can perform most IR tasks, and their ability to complete these tasks does not differ significantly from those in patients with other BSA.

Speed of recovery after arthroscopic rotator cuff repair.

BACKGROUND: The purpose of this study was to delineate the time taken to achieve maximum improvement (plateau of recovery) and the degree of recovery observed at various time points (speed of recovery) for pain and function after arthroscopic rotator cuff repair. METHODS: An institutional shoulder surgery registry query identified 627 patients who underwent arthroscopic rotator cuff repair between 2006 and 2015. Measured range of motion, patient satisfaction, and patient-reported outcome measures were analyzed for preoperative, 3-month, 6-month, 1-year, and 2-year intervals. Subgroup analysis was performed on the basis of tear size by retraction grade and number of anchors used. RESULTS: As an entire group, the plateau of maximum recovery for pain, function, and motion occurred at 1 year. Satisfaction with surgery was >96% at all time points. At 3 months, 74% of improvement in pain and 45% to 58% of functional improvement were realized. However, only 22% of elevation improvement was achieved (P < .001). At 6 months, 89% of improvement in pain, 81% to 88% of functional improvement, and 78% of elevation improvement were achieved (P < .001). Larger tears had a slower speed of recovery for Single Assessment Numeric Evaluation scores, forward elevation, and external rotation. Smaller tears had higher motion and functional scores across all time points. Tear size did not influence pain levels. CONCLUSION: The plateau of maximum recovery after rotator cuff repair occurred at 1 year with high satisfaction rates at all time points. At 3 months, approximately 75% of pain relief and 50% of functional recovery can be expected. Larger tears have a slower speed of recovery.

Impact of Urinary Catheterization on Postoperative Outcomes After Roux-En-Y Gastric Bypass Surgery in Propensity-Matched Cohorts.

BACKGROUND: The impact of urinary catheter avoidance in bariatric enhanced recovery after surgery (ERAS) protocols is yet to be established. The purpose of the current study is to determine whether urinary catheter use in patients undergoing Roux-en-Y gastric bypass (RYGB) procedures has an effect on postoperative outcomes. METHODS: An institutional database was utilized to identify adult patients undergoing primary minimally invasive RYGB surgery. Outcomes included incidence of urinary tract infection (UTI) within 30 days postoperatively, 30-day readmission rates, proportion of patients discharged after postoperative day 1 (delayed discharge), length of stay (LOS), and operating room time. These were compared between propensity-matched groups with and without urinary catheter placement. RESULTS: There were no significant differences in postoperative UTI's (2.2% for both cohorts, P = .593) or 30-day readmission rates for patients with and without urinary catheters (6.6% and 4.4%, respectively, P = .260). Mean LOS (1.7 vs. 1.5 days, P = .001) and the proportion of patients having a delayed discharge (47.3% vs. 33.7%, P = .001) was greater in patients with a catheter. Operating room time was longer in the urinary catheter group (221.8 vs. 207.9 minutes, P = .002). DISCUSSION: Avoidance of indwelling urinary catheters in RYGB surgical patients decreased delayed discharges and LOS without affecting readmission or reoperation rates. Therefore, we recommend that avoidance of urinary catheters in routine RYGB surgery be considered for inclusion into standardized ERAS protocols. Urinary catheters should continue to be utilized in select cases, however, as these were not shown to affect rate of UTIs.

Comparative Outcomes of Various Combinations of Bilateral Shoulder Arthroplasty.

Background: In the setting of bilateral shoulder arthroplasty (BSA), differences in functional outcomes and motion between anatomic total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA) are unknown. The purpose of this study was to compare the effectiveness of treatment for various combinations of TSA procedures. Methods: A review of prospectively collected data from an institutional shoulder surgery repository was performed for patients who underwent any combination of bilateral TSA or RSA surgery. Based on the combination of shoulder arthroplasty, patients were divided into the following subgroups: bilateral TSA (TSA/TSA), bilateral RSA (RSA/RSA), or unilateral TSA with contralateral RSA (TSA/RSA). A total of 73 patients (146 shoulders), with a minimum of 2-year follow-up, who underwent any combination of bilateral TSA or RSA from 2007 to 2014 were included. Pre- and postoperative patient-reported outcome measures and measured motion were evaluated between the 3 groups. Results: There were 47 TSA/TSA, 17 RSA/RSA, and 9 TSA/RSA patients with a mean age of 72 years and mean follow-up of 51 months. Preoperatively, TSA/TSA had significantly higher Simple Shoulder Test scores, Visual Analog Scale (VAS) function, active elevation, and active external rotation compared with RSA/RSA. Postoperative scores were significantly superior in TSA/TSA compared with other combinations of shoulder arthroplasty except VAS pain and function. Change in pre- to postoperative (effectiveness of treatment) internal rotation was superior in the TSA/TSA group compared with RSA/RSA and TSA/RSA; however, no other differences were observed. Conclusions: Bilateral TSA patients have higher preoperative function and motion. Although some postoperative outcomes differ among combinations of BSA, the overall effectiveness of treatment for patients undergoing BSA is similar between various combinations of arthroplasty.

Effect of biceps tenodesis on speed of recovery after arthroscopic rotator cuff repair.

BACKGROUND: Concomitant biceps tendon pathology is often present in patients undergoing rotator cuff repair (RCR). Management of biceps pathology has been reported to influence outcomes of RCR; however, the impact on the pace of recovery remains unclear. The purpose of this study was to analyze the effects of simultaneous RCR with biceps tenodesis (RCR-BT) on time to achieve maximum improvement and recovery speed for pain and function. METHODS: A retrospective review of 535 patients who underwent primary RCR for full-thickness tears. Patients treated with simultaneous RCR-BT were compared with RCR-only. Outcome measures and motion were recorded at preoperative routine postoperative intervals. Plateau in maximal improvement and recovery speed were analyzed for both pain and functional recovery. RESULTS: Baseline American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) function was significantly lower for the RCR-BT cohort (20.5) compared with RCR-only (23.9; P = .008). For visual analog scale (VAS) pain and measured motion, the plateau in maximal improvement occurred at 6 months for RCR-BT compared with 12 months for the RCR-only group. The remainder of the patient-reported outcome measures took 12 months to achieve a plateau in maximal improvement. At 3 months, 79% of improvement in pain and 42%-49% of functional improvement was achieved in the RCR-BT cohort. Similarly, at 3 months, the RCR-only cohort achieved 73% of pain improvement and 36%-57% of functional improvement at 3 months. CONCLUSION: Patients requiring RCR with simultaneous biceps tenodesis have lower baseline ASES function and earlier postoperative plateaus in pain relief and motion improvement following surgery. Nonetheless, the speed of recovery was not influenced by the biceps tenodesis.

Effect of opioid dependence or abuse on opioid utilization after shoulder arthroplasty.

AIM: To examine whether opioid dependence or abuse has an effect on opioid utilization after anatomic or reverse total shoulder arthroplasty (TSA). METHODS: All anatomic TSA (ICD-9 81.80) and reverse shoulder arthroplasty (RSA) (ICD-9 81.88) procedures from 2007 to 2015 were queried from within the Humana claims database utilizing the PearlDiver supercomputer (Colorado Springs, CO). Study groups were formed based on the presence or absence of a previous history of opioid dependence (ICD-9 304.00 and 304.03) or abuse (ICD-9 305.50 and 305.53). Opioid utilization among the groups was tracked monthly up to 1 year post-operatively utilizing National Drug Codes. A secondary analysis was performed to determine risk factors for pre-operative opioid dependence or abuse. RESULTS: Two percent of TSA (157 out of 7838) and 3% of RSA (206 out of 6920) patients had a history of opioid dependence or abuse. For both TSA and RSA, opioid utilization was significantly higher in opioid dependent patients at all post-operative intervals (P < 0.01) although the incidence of opioid use among groups was similar within the first post-operative month. After TSA, opioid dependent patients were over twice as likely to fill opioid prescriptions during the post-operative months 1-12. Following RSA, opioid dependent patients were over 3 times as likely to utilize opioids from months 3-12. Age less than 65 years, history of mood disorder, and history of chronic pain were significant risk factors for pre-operative opioid dependence/abuse in patients who underwent TSA or RSA. CONCLUSION: Following shoulder arthroplasty, opioid use between opioid-dependent and non-dependent patients is similar within the first post-operative month but is greater among opioid-dependent patients from months 2-12.

Comorbidity effect on speed of recovery after arthroscopic rotator cuff repair.

BACKGROUND: Comorbidities have been shown to affect rotator cuff healing and postoperative outcomes. The purpose of this study was to analyze the effect of comorbidities on speed of recovery (SOR) and overall outcomes after arthroscopic rotator cuff repair (RCR). METHODS: We identified 627 patients who underwent primary arthroscopic RCR from 2006 to 2015. Measured motion and patient-reported outcome measures for pain and function were analyzed for preoperative, 3-month, 6-month, and 1-year intervals. Subgroup analysis of overall outcome and plateau in maximum improvement was performed for diabetes, smoking, obesity, hypercholesterolemia, and age. RESULTS: Diabetic patients had worse pain (visual analog scale for pain) and functional outcome (American Shoulder and Elbow Surgeons function, Simple Shoulder Test, visual analog scale for function, and elevation) scores at 6 months and 1 year (P < .05), with an earlier plateau in recovery (6 months) for nearly all variables. Smoking had no impact on postoperative outcome scores; however, plateaus occurred earlier in smokers (6 months). Obese patients had worse American Shoulder and Elbow Surgeons function score and external rotation at 1 year (P < .05) with similar plateau points. No significant differences were observed in outcomes for patients with hypercholesterolemia; however, plateaus for Single Assessment Numeric Evaluation and motion occurred earlier (6 months). Outcome scores for patients older than 65 years were not significantly different from those for younger patients. CONCLUSION: After arthroscopic RCR, SOR for pain outpaced that for function and motion. Diabetic patients had worse outcomes and earlier plateau points. Earlier plateaus were seen for smokers and for motion in patients with obesity or hypercholesterolemia. Obese patients showed lower functional scores and external rotation. Age did not significantly influence SOR.

Morbid obesity and 1-year costs after elbow dislocation.

BACKGROUND: Morbid obesity has been linked with serious associated injuries following dislocations of the knee. While similar devastating injuries have been observed following elbow dislocations in the obese, no study to date has characterized the financial impact of elbow dislocations in the morbidly obese population. PURPOSE: The purpose of this study is to determine the impact of morbid obesity on 1-year costs related to elbow dislocation. METHODS: A retrospective query of the Medicare Standard Analytic Files database was performed for patients sustaining elbow dislocation from 2005 to 2014. 1-year reimbursement costs from the initial open or closed reduction procedures were compared for morbidly obese (BMI ≥ 40 kg/m2) patients versus those without morbid obesity (BMI < 40 kg/m2). Cohorts were matched based on age and gender. Total reimbursement costs associated with a diagnosis of elbow dislocation and/or reduction were analyzed. RESULTS: We identified 182 morbidly obese patients and 422 patients without morbid obesity who underwent open or closed reduction for elbow dislocation. 102 patients with 1-year cost data remained in each cohort after matching. Mean 1-year reimbursement costs related to elbow dislocation were significantly greater in morbidly obese patients ($6227.43 vs $4225.71, p = 0.006). CONCLUSION: 1-year costs related to elbow dislocation are significantly higher in morbidly obese patients. The increased costs likely reflect the complexity of managing dislocations in the obese population. Difficulties maintaining closed reduction, longer and more challenging surgeries with a higher likelihood on intra- and post-operative complications, and a higher risk of peri-operative medical complications may all contribute to these increased costs.
