Type A Thymoma with Spinal and Cranial Metastases: A Case Report.

Introduction: While metastases of malignant thymomas have been shown, type A thymomas are often treated as benign. Type A thymomas often have excellent response to treatment, low recurrence rate, and a small malignant potential. To date, there have been no reports of type A thymomas with spinal metastases. Case Report: A 66-year-old female with a type A thymoma metastatic to the T7 and T8 vertebral bodies and brain, with associated pathologic burst fracture, collapse of T7, and significant focal kyphosis . The patient underwent successful T7-T8 posterior corpectomy and T4-T11 posterior spinal fusion. At 2 years of follow-up, she was ambulating without assistive devices and completed spinal radiation and initial chemotherapy. Conclusion: Metastatic type A thymoma is a rare phenomenon. While traditionally thought to have low recurrence rates and overall excellent survival rates, our case suggests that the biologic malignant potential of a type A thymoma may not be fully understood.

WALANT Technique versus Sedation for Endoscopic Carpal Tunnel Release.

BACKGROUND: This study sought to investigate complication rates/perioperative metrics after endoscopic carpal tunnel release (eCTR) via wide-awake, local anesthesia, no tourniquet (WALANT) versus sedation or local anesthesia with a tourniquet. METHODS: Patients aged 18 years or older who underwent an eCTR between April 28, 2018, and December 31, 2019, by 1 of 2 fellowship-trained surgeons at our single institution were retrospectively reviewed. Patients were divided into 3 groups: monitored anesthesia care with tourniquet (MT), local anesthesia with tourniquet (LT), and WALANT. RESULTS: Inclusion criteria were met by 156 cases; 53 (34%) were performed under MT, 25 (16%) under LT, and 78 (50%) under WALANT. The MT group (46.1 ± 9.7) was statistically younger compared with LT (56.3 ± 14.1, P = .007) and WALANT groups (53.5 ± 15.8, P = .008), F(2, 153) = 6.465, P = .002. Wide-awake, local anesthesia, no tourniquet had decreased procedural times (10 minutes, SD: 2) compared with MT (11 minutes, SD: 2) and LT (11 minutes, SD: 2), F(2, 153) = 5.732, P = .004). Trends favored WALANT over MT and LT for average operating room time (20 minutes, SD: 3 vs 32 minutes, SD: 6 vs 23 minutes, SD: 3, respectively, F(2, 153) = 101.1, P < .001), postanesthesia care unit time (12 minutes, SD: 7 vs 1:12 minutes, SD: 26 vs 20 minutes, SD: 22, respectively, F(2, 153) =171.1, P < .001), and door-to-door time (1:37 minutes, SD: 21 vs 2:51 minutes, SD: 40 vs 1:46 minutes, SD: 33, respectively, F(2, 153) = 109.3, P < .001). There were no differences in complication rates. CONCLUSIONS: Our data suggest favorable trends for patients undergoing eCTR via WALANT versus MT versus LT.

Wide Awake Local Anesthesia No Tourniquet Technique in Hand Surgery: The Patient Experience.

BACKGROUND: We attempted to evaluate patient satisfaction and overall experience during wide awake, local anesthesia, with no tourniquet (WALANT) hand surgery and quantify surgery-related outcomes. METHODS: We conducted a retrospective analysis of patient demographics, comorbidities, and patient reported outcomes via Single Assessment Numeric Evaluation (SANE) scores collected pre- and postoperatively of patients undergoing WALANT surgery by the 2 participating senior authors. A solution of 1% lidocaine with 1:100,000 epinephrine was used by 1 surgeon, while the other used a 1:1 ratio of 1% lidocaine with 1:100,000 epinephrine and 0.5% bupivacaine for local anesthetic injection. Patients were administered a postoperative survey to assess patient experience, including anxiety and pain levels, and overall satisfaction in the perioperative period. RESULTS: Overall, 97.7% of patients indicated that they would undergo a WALANT-style surgery if indicated in the future, 70.5% ate the day of surgery, and a total of 39.1% of patients reported driving to and from surgery. Postoperative SANE scores increased as compared with preoperative scores across all patients. The use of combination 1% lidocaine with 1:100,000 epinephrine and 0.5% bupivacaine was associated with lower intraoperative and postoperative visual analog scale pain scores. CONCLUSIONS: WALANT hand surgery was generally well tolerated with excellent surgical outcomes. Patients reported ease of preparation for surgery, faster recovery, and lack of anesthetic side effects as the main benefits of wide-awake surgery. Combination use of lidocaine and bupivacaine may be better than lidocaine alone with respect to pain control in the initial recovery period.

The utility of the biceps palpation-rotation test in diagnosing partial distal biceps tendon tears.

BACKGROUND: Partial tears of the distal biceps tendon can be difficult to diagnose based on clinical examination and magnetic resonance imaging (MRI). METHODS: Patients from a single surgeon's practice from 2000 to 2018 with a partial distal biceps tendon tear were retrospectively reviewed to determine the utility of the distal biceps palpation-rotation test in the detection of partial tears. This test is performed by palpating the bicipital tuberosity at the lateral forearm while ranging the forearm from supination to pronation with the arm adducted at the patient's side and the elbow flexed to 90°. A positive test elicits tenderness at the tuberosity with the arm in pronation but not in supination. Examination findings were correlated with MRI reports confirming a partial tear. Twelve cadaveric arms were dissected to determine overall pronosupination range of motion, the degree of pronation at which the bicipital tuberosity is maximally palpable, and anatomic measurements of the bicipital tuberosity to guide the optimal technique when carrying out the maneuver. RESULTS: Ninety-nine patients were diagnosed with a partial distal biceps tendon, of whom 34 had available MRI reports and complete physical examination documentation. Thirty-three of 34 patients (97%) had partial tears on MRI. The hook test was negative in all cases. All patients had tenderness with resisted supination. In those with MRI-confirmed partial tears, the palpation-rotation test was positive in all patients (100% sensitivity). The bicipital tuberosity was maximally palpated at the dorsolateral forearm at a mean 20° of pronation, and the proximal and distal boundaries of the radial tuberosity were 2.5 cm and 5.3 cm, on average, distal to the radial head, respectively. CONCLUSION: A positive palpation-rotation test was seen in 33 of 33 patients (100% sensitivity), as correlated with MRI. The combination of an intact distal biceps tendon within the antecubital fossa, tenderness on resisted supination, and a positive palpation-rotation test are highly suggestive of a partial distal biceps tendon tear.

Outcomes of reverse shoulder arthroplasty following failed superior capsular reconstruction.

BACKGROUND: Superior capsular reconstruction (SCR) can be used for massive irreparable rotator cuff tears in the absence of significant degenerative changes; however, those who fail an SCR may require reverse shoulder arthroplasty (RSA). The effect of a previously performed SCR on outcomes following RSA remains unknown. METHODS: Subjects who underwent RSA from May 2015 to January 2021 at 2 separate institutions were retrospectively identified through prospectively collected databases. Patients who underwent RSA after failed SCR were matched to those who underwent RSA after failed rotator cuff repair (RCR) based on the number of previous ipsilateral shoulder procedures (n = 1, 2, ≥3) and secondarily by age within 5 years. American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, Single Assessment Numeric Evaluation (SANE), visual analog scale (VAS) for pain, and Western Ontario Osteoarthritis of the Shoulder index (WOOS) scores were compared between groups. The minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) thresholds were calculated to determine clinically relevant differences between groups. RESULTS: Forty-five patients were included (32 RSA following RCR, 13 following SCR). There were more smokers (P = .001) and worker's compensation cases (P = .034) in the SCR group. The RCR cohort was older (P = .007) and had a greater incidence of mental health (P > .999) and somatic disorders (P = .698), although these did not reach statistical significance. The mean follow-up for the RCR and SCR groups were 24.2 ± 23.3 and 20.4 ± 14.9 months following RSA, respectively (P = .913). The time from index RCR or SCR to RSA were 94.4 ± 22.2 and 89.2 ± 5.3 months, respectively (P = .003). Pre- and postoperative range of motion were similar between groups, as was the overall change in forward flexion (P = .879), abduction (P = .971), and external rotation (P = .968) following RSA. The RCR group had lower postoperative VAS pain (P = .009), higher SANE (P = .015), higher ASES (P = .008), and higher WOOS (P = .018) scores. The percentage achieving the MCID (P = .676) and SCB (P > .999) were similar; however, 56.7% of the RCR group met the SANE PASS threshold compared with 0.0% in the SCR group (P = .005). There were no differences in postoperative complications (P = .698) or revision rates (P = .308) following RSA between cohorts. CONCLUSION: When matched for number of previous procedures to the ipsilateral extremity and age, patients who underwent RSA following failed SCR had worse clinical outcome scores than their RSA following failed RCR counterparts. No patient in the SCR group met the SANE PASS threshold, whereas more than half of the RCR group did.

Three-Dimensional Footprint Mapping of the Deltoid and Trapezius: Anatomic Pearls for Acromioclavicular Joint Reconstruction.

PURPOSE: To perform a quantitative anatomic evaluation of the deltoid and trapezius footprints in relation to the lateral clavicle and acromioclavicular (AC) joint capsule to assist in surgical technique of AC joint reconstructions. METHODS: Fourteen fresh-frozen human cadaveric shoulders from 9 donors were analyzed. Meticulous dissection of the deltoid origin and trapezius insertions to the clavicle and AC joint was performed. Footprints were reconstructed using a MicroScribe digitizer. The inferior extension of the deltoid origin beneath the lateral clavicle and the footprints of the deltoid and trapezius onto the acromioclavicular ligamentous complex (ACLC) were quantified. Reproducibility was assessed by redigitizing 5 shoulders in a blinded and random fashion. RESULTS: The anterior deltoid fibers extended on average 4.0 ± 1.6 mm inferiorly with respect to the anteroinferior clavicular ridge and attached to 90.9 ± 7.3% of the anterior ACLC. The trapezius inserted onto the posterior and superior ACLC, covering 15.3 ± 3.4% of the anterior-posterior width of the superior capsule. The deltopectoral interval was 6 cm, or 37% the length of the clavicle from the distal end of the clavicle. CONCLUSIONS: The deltoid has superior, anterior, and not as well described, inferior attachments to the lateral clavicle. Furthermore, the deltoid and trapezius muscles have intimate attachments to the AC joint capsule, particularly the trapezius to the posterior and posterosuperior capsule. Lastly, the deltoid origin attaches to the lateral 6 cm of the clavicle. CLINICAL RELEVANCE: Subperiosteal elevation of the deltoid off the lateral clavicle starting superiorly, anteriorly, and lastly inferiorly will reduce deltoid muscle injury and improve visibility of the coracoid process during reconstruction. Furthermore, knowledge of the attachments of the deltoid and trapezius to the ACLC may help limit iatrogenic injury to these dynamic stabilizers.

Open and arthroscopic management of femoroacetabular impingement: a review of current concepts.

Femoroacetabular impingement (FAI) is a common femoral and/or acetabular abnormality that can cause progressive damage to the hip and osteoarthritis. FAI can be the result of femoral head/neck overgrowth, acetabular overgrowth or both femoral and acetabular abnormalities, resulting in a loss of native hip biomechanics and pain upon hip flexion and rotation. Radiographic evidence can include loss of sphericity of the femoral neck (cam impingement) and/or acetabular retroversion with focal or global overcoverage (pincer impingement). Operative intervention is indicated in symptomatic patients after failed conservative management with radiographic evidence of impingement and minimal arthritic changes of the hip, with the goal of restoring normal hip biomechanics and reducing pain. This is done by correcting the femoral head-neck relationship to the acetabulum through femoral and/or acetabular osteoplasty and treatment of concomitant hip pathology. In pincer impingement cases with small lunate surfaces, reverse periacetabular osteotomy is indicated as acetabular osteoplasty can decrease an already small articular surface. While surgical dislocation is regarded as the traditional gold standard, hip arthroscopy has become widely utilized in recent years. Studies comparing both open surgery and arthroscopy have shown comparable long-term pain reduction and improvements in clinical measures of hip function, as well as similar conversion rates to total hip arthroplasty. However, arthroscopy has trended toward earlier improvement, quicker recovery and faster return to sports. The purpose of this study was to review the recent literature on open and arthroscopic management of FAI.

Authorship Proliferation of Research Articles in Top 10 Orthopaedic Journals: A 70-Year Analysis.

INTRODUCTION: Scholarly impact has been used to measure faculty productivity and academic contribution throughout academia. Traditionally, the number of articles authored has been the primary metric for scholarly impact regarding academic promotion and reputation. We hypothesize that over time, the nature of authorship has evolved to include more authors per research article throughout the history of orthopaedic literature. METHODS: Bibliometric data for all original research article abstracts were extracted from PubMED for the 10 highest rated H5-index orthopaedic clinical journals ("American Journal of Sports Medicine," "Journal of Bone and Joint Surgery American Volume," "Clinical Orthopaedics and Related Research "Spine," "Knee Surgery, Sports Traumatology, Arthroscopy," "Journal of Arthroplasty," "Arthroscopy," "The Spine Journal," "European Spine Journal," and "Journal of Bone and Joint Surgery British Volume/Bone & Joint Journal"). The number of authors per article was then analyzed over time using the Cochran-Armitage trend test. RESULTS: A total of 106,529 original articles were analyzed over a 70-year period. The number of authors increased significantly over time from a mean of 1.4 authors (SD: 0.62) in 1946 to 5.7 authors (SD: 3.1) in 2019, representing an average relative increase of 4.3% per year (P < 0.05). The three oldest journals had the lowest average authors (Journal of Bone and Joint Surgery Am Volume: 1946, mean 3.7 authors [SD: eight]; Journal of Bone and Joint Surgery Br Volume/Bone & Joint Journal: 1948, mean: 3.6 authors [SD: 7.5]; Clinical Orthopaedics and Related Research: 1963, mean 3.3 authors [SD: 2.9]). The three newest journals had the highest average authors (European Spine Journal: 1992, mean 5.3 authors [SD: 3.3]; Knee Surgery, Sports Traumatology, Arthroscopy: 1993, mean 5.5 authors [SD: 6.7 authors; The Spine Journal: 2003, mean 5.2 authors [SD: 3.6]). DISCUSSION: Original research articles published in orthopaedic academic journals have experienced an increase in authorship over time. Although our data cannot explain what has driven this change, increasing cooperation between collaborators may represent less contribution per author over time.

Osteosarcoma Mimicking Tenosynovial Giant Cell Tumor of the Hip in a Pediatric Patient: A Case Report.

CASE: A 17-year-old boy presented to the clinic complaining of right hip pain after soccer participation. Clinical findings and imaging studies led to the diagnoses of femoroacetabular impingement and diffuse tenosynovial giant cell tumor (TGCT). Comprehensive arthroscopic management and biopsy revealed a diagnosis of osteosarcoma. The patient subsequently underwent chemotherapy, surgical resection, and reconstruction. CONCLUSION: Osteosarcoma of the proximal femur may mimic TGCT on imaging studies because osteosarcoma may show changes suggestive of inflammation. We recommend heightened clinical awareness and a comprehensive differential workup in the management of presumed TGCT about the hip in the pediatric patient population.

The Statistical Fragility of Platelet-Rich Plasma in Rotator Cuff Surgery: A Systematic Review and Meta-analysis.

BACKGROUND: The practice of evidence-based medicine relies on objective data to guide clinical decision-making with specific statistical thresholds conveying study significance. PURPOSE: To determine the utility of applying the fragility index (FI) and the fragility quotient (FQ) analysis to randomized controlled trials (RCTs) evaluating the utilization of platelet-rich plasma (PRP) in rotator cuff repairs (RCRs). STUDY DESIGN: Systematic review and meta-analysis. METHODS: RCTs pertaining to the utilization of PRP in surgical RCRs published in 13 peer-reviewed journals from 2000 to 2020 were evaluated. The FI was determined by manipulating each reported outcome event until a reversal of significance was appreciated. The associated FQ was determined by dividing the FI by the sample size. RESULTS: Of the 9746 studies screened, 19 RCTs were ultimately included for analysis. The overall FI incorporating all 19 RCTs was only 4, suggesting that the reversal of only 4 events is required to change study significance. The associated FQ was determined as 0.092. Of the 43 outcome events reporting lost to follow-up data, 13 (30.2%) represented lost to follow-up >4. CONCLUSION: Our analysis suggests that RCTs evaluating PRP for surgical RCRs may lack statistical stability with only a few outcome events required to alter trial significance. Therefore, we recommend the reporting of an FI and an FQ in conjunction with P value analysis to carefully interpret the integrity of statistical stability in future comparative trials. CLINICAL RELEVANCE: Clinical decisions are often informed by statistically significant results. Thus, a true understanding of the robustness of the statistical findings informing clinical decision-making is of critical importance.

Effectiveness of topical adjuvants in reducing biofilm formation on orthopedic implants: an in vitro analysis.

BACKGROUND AND HYPOTHESIS: The treatment of periprosthetic joint infection is complicated by the presence of residual biofilm, which resists eradication owing to bacterial adherence to orthopedic implants. The purpose of this study was to compare Bactisure (Zimmer Biomet, Warsaw, IN, USA), povidone-iodine (Betadine), and chlorhexidine gluconate solution (Irrisept; Irrimax, Gainesville, FL, USA) in reducing biofilm formation of Staphylococcus aureus, Staphylococcus epidermidis, and Cutibacterium acnes inoculated on cobalt-chrome, titanium, and stainless steel disks, representing metals commonly used for shoulder arthroplasty. The hypothesis was that there would be no significant difference in biofilm reduction among the 3 topical adjuvants. METHODS: Strains of S aureus (ATCC 35556), S epidermidis (ATCC 35984), and C acnes (LMG 16711) were grown on cobalt-chrome, titanium, and stainless steel disks. For each strain, the disks were divided into 4 groups: (1) control, (2) povidone-iodine (Betadine), (3) chlorhexidine gluconate (Irrisept), and (4) Bactisure. Bacteria were grown on 5% sheep blood agar plates. Biofilm eradication was quantified using adenosine triphosphate bioluminescence and compared with controls 48 and 72 hours after implementation of the topical adjuvant. RESULTS: At 72 hours after implementation of the topical adjuvant, a statistically significant reduction in colony-forming units was observed for all topical adjuvants across all tested metals, as compared with their respective control. With respect to the topical adjuvants themselves, Bactisure more consistently demonstrated the most significant reduction in colony-forming units across all bacteria when the tested medium was adjusted for, with the exception of S aureus, which showed similar results to Betadine at 72 hours. CONCLUSION: By use of commonly encountered topical adjuvants on S aureus-, S epidermidis-, and C acnes-inoculated disks of various implant metals, a significant reduction in biofilm production was observed. Bactisure, a recent Food and Drug Administration-approved topical adjuvant, demonstrated the overall greatest efficacy of the agents studied.

Where Do We Stand Today on Racial and Ethnic Health Inequities? Analysis of Primary Total Knee Arthroplasty from a 2011-2017 National Database.

BACKGROUND: The objective of this study was to present contemporary national data on the state of racial and ethnic disparities pertaining to primary total knee arthroplasty (TKA) in the USA. METHODS: The 2011-2017 National Surgical Quality Improvement Program was used to capture all patients who underwent primary TKA. The study outcomes were differences in demographic, comorbidity burden, perioperative factors, procedure utilization, hospital length of stay (LOS), and 30-day outcomes. The five major minority groups as defined by the National Institutes of Health were compared to non-Hispanic Whites. RESULTS: In total, 262,954 patient records were analyzed, with racial identification available on 230,712 patients (87.7%). White patients accounted for 72.5% of all TKA procedures. There were higher rates of diabetes, hypertension, anemia, and prolonged surgery times among racial and ethnic minorities (p < 0.001). Baseline disparities were especially pronounced among non-Hispanic Blacks/African Americans who were also like to have higher rates of tobacco smoking and CHF (p < 0.001). After controlling for baseline differences, significant disparities in outcomes persisted, especially among Blacks/African Americans and Hispanics/Latinos who had higher odds for experiencing complications and readmissions (p < 0.001). All racial and ethnic groups, except Asians, had longer LOS (p < 0.001). Asian patients had significantly lower rates of readmissions, reoperations, and overall complications (p < 0.001). CONCLUSION: Racial and ethnic disparities remain a public health challenge for patients undergoing TKA. While initiatives aimed at improving preoperative disease-burden and comorbidity profiles represent an important step, they alone are insufficient to fully account for or eliminate the disparities in TKA outcomes.

One Versus 2-Stage Revision for Shoulder Arthroplasty Infections: A Systematic Review and Analysis of Treatment Selection Bias.

BACKGROUND: There is controversy regarding the optimal treatment for infection following shoulder arthroplasty. The purpose of this systematic review is to analyze the bias in treatment selection, infection clearance rates, and functional outcomes after 1 versus 2-stage revision surgery for periprosthetic shoulder infections. METHODS: A systematic search strategy following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted in 4 phases. Articles were identified using MEDLINE (PubMed), Embase (Elsevier), and Cochrane Library databases with Boolean search terms related to infection after shoulder arthroplasty. Included articles were analyzed for quality, and data were extracted for use. Preoperative treatment selection bias was analyzed and postoperative infection clearance rates and functional outcome scores were compared between 1 and 2-stage revision surgery for periprosthetic shoulder infection. RESULTS: Overall, 163 1-stage shoulder procedures and 289 2-stage shoulder procedures were included in the analysis. Cutibacterium acnes was the organism most frequently grown on culture (37%) followed by coagulase-negative Staphylococcus (19%). The overall infection clearance rate was 95.6% for 1-stage and 85.2% for 2-stage procedures. In a comparison of the change in outcome scores from preoperatively to postoperatively between 1-stage and 2-stage revision, the Constant-Murley Score (CMS) improved 21.0 points (1-stage) versus 22.8 points (2-stage), the American Shoulder and Elbow Surgeons (ASES) score improved 26.2 points versus 33.6 points, and the Simple Shoulder Test (SST) score improved 3.5 points versus 6.4 points, respectively. Overall, 23 of 26 studies cited a reason for selection of a 1 versus 2-stage procedure, which was due to standard treatment protocol in 10 studies, based on the timing of the infection (acute versus subacute versus chronic) in 5, due to a combination of factors (age, comorbidities, intraoperative appearance, adequacy of debridement, bone loss) in 6, and due to preoperative identification of a specific organism in 2. CONCLUSIONS: One-stage revisions resulted in higher infection clearance rates; however, 2-stage revisions resulted in greater functional improvement as measured with ASES and SST scores from the preoperative assessment to the final postoperative follow-up. The decision between 1 and 2-stage revisions is due to a combination of factors including pathogen type, timing of infection, findings on the preoperative clinical examination, the patient's own decision, the surgeon's preference, and the intraoperative soft-tissue/osseous appearance, which may have biased the overall results. There is no consensus in the literature on the decision between 1 and 2-stage treatment for periprosthetic shoulder infection, which is based on a combination of factors. However, both treatment strategies are effective in treating periprosthetic shoulder infection. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Combating the Opioid Epidemic: Experience with a Single Prescription for Total Joint Arthroplasty.

BACKGROUND: Despite advances in perioperative total joint arthroplasty (TJA) pain protocols, opiates continue to play a major role in postoperative pain control. This brief communication reports our experience with a restrictive opioid protocol allowing patients only a single prescription of low-dose opioids. METHODS: One hundred consecutive elective, primary, and revision TJAs were analyzed. All patients received preoperative counseling and multimodal analgesia. Counseling involved discussion of patient expectations on postoperative pain management, weaning off opioids before surgery, and emphasis that opioid refills were not permitted. Ninety-day outcomes including pain-related phone calls, opioid refill requests, emergency room visits, complications, and readmissions were assessed. Opioid dispensing was tracked using our state prescription monitoring program. RESULTS: There was a high prevalence of preoperative opioid use, depression, and anxiety (25%, 34%, and 39%, respectively). Sixty-eight percent of chronic opioid users were able to wean off opioids before surgery. The average initial prescription of opioids was equivalent to 48 pills of 5 mg oxycodone. There were only 10 pain-related phone calls from 9 patients; all were using opioids preoperatively, with only one patient requesting a refill. All pain-related phone calls occurred in the first week after surgery. There were no emergency room visits, complications, or readmissions related to pain. CONCLUSIONS: A single prescription of low-dose opioids was sufficient for patients undergoing TJA when using preoperative patient preparation and multimodal analgesia. Standardized guidelines are needed to guide best practices for patient education and pain management, especially in patients on chronic opioid therapy. This information will help implement evidence-based strategies to accelerate the decline of opioid use and hopefully pave the way for opioid-free TJA.

Brachialis Muscle Tendon Rupture of the Distal Ulnar Attachment in a Competitive Weight Lifter.

Isolated tears of the brachialis muscle are rare and often take on the clinical appearance of other pathology, such as a distal biceps brachii tendon tear or an intramuscular tumor, thus making diagnosis especially difficult. The authors describe the case of a 31-year-old competitive male weight lifter who was found to have a full-thickness tear of the brachialis tendon at its distal ulnar attachment after performing a 40.8-kg biceps curl. The authors describe the differential diagnosis, radiographic findings, and methods used that led to the diagnosis and also provide a comprehensive review of the literature on brachialis muscle injuries. The patient decided to proceed with conservative management consisting of a period of rest and physical therapy. At 10 months after the injury, the patient went back to weightlifting and biceps curls. He had progressed to full strength and had returned to all weightlifting activities at final follow-up. Isolated full-thickness brachialis muscle ruptures can be treated successfully with conservative management, including rest and physical therapy. [Orthopedics. 2019; 42(3):e339-e342.].

Regional Variations of Medicare Physician Payments for Hand Surgery Procedures in the United States.

BACKGROUND: Medicare reimbursement is known to exhibit geographic variation for inpatient orthopedic procedures. This study determined whether US geographic variations also exist for commonly performed hand surgeries. METHODS: Using the Medicare Provider Utilization and Payment Data (2012-2013) from Centers for Medicare & Medicaid Services, we analyzed regional physician charges/payments for common outpatient hand surgeries. RESULTS: The most commonly performed procedures in the United States were open carpal tunnel release (n = 21 944), trigger finger release (n = 15 345), endoscopic carpal tunnel release (n = 7106), and basal joint arthroplasty/ligament reconstruction and tendon interposition (n = 2408). A range of average Medicare physician reimbursements existed based on geographic region for basal joint arthroplasty ($669-$571), endoscopic carpal tunnel release ($400-$317), open carpal tunnel release ($325-$261), and trigger finger release ($215-$167). The latter three exhibited statistically significant variation across geographic regions with regard to both charges and physician reimbursement. However, the overall percentage physician reimbursement (70%-79%) to charges was similar across all geographic regions. CONCLUSIONS: In conclusion, further research is warranted to determine why regional or geographic variations in physician payments exist in the United States for commonly performed hand surgeries.

Extensor Mechanism Reconstruction for Chronic Patellar Fracture.

Patients with displaced patellar fractures typically present with disruption to the extensor mechanism requiring acute surgical intervention. Chronic patellar fractures with disruption of the extensor mechanism are uncommon, and few surgical options are available. The authors present a patient who sustained a fracture to the inferior pole of the patella in Africa 5 years prior that was managed conservatively with bands and a brace. He decided to pursue surgical intervention because of difficulties with leg extension, weakness, and ambulation. The patient underwent a novel reconstruction of his chronic extensor mechanism loss with a combination of inferior pole patellar fracture excision, z-plasty and lengthening of the quadriceps tendon, and Achilles tendon reconstruction of the patellar tendon with both hamstring autograft and acellular human dermal matrix allograft augmentation of the entire reconstruction construct. At the final 2-year follow-up, the patient had restored active extension with no extensor lag and had returned to his preinjury activities, including running and playing soccer.

Insurance status affects postoperative morbidity and complication rate after shoulder arthroplasty.

BACKGROUND: Shoulder arthroplasty is an effective procedure for managing patients with shoulder pain secondary to end-stage arthritis. Insurance status has been shown to be a predictor of patient morbidity and mortality. The current study evaluated the effect of patient insurance status on perioperative outcomes after shoulder replacement surgery. METHODS: Data between 2004 and 2011 were obtained from the Nationwide Inpatient Sample. Analysis included patients undergoing shoulder arthroplasty (partial, total, and reverse) procedures determined by International Classification of Disease, 9th Revision procedure codes. The primary outcome was medical and surgical complications occurring during the same hospitalization, with secondary analyses of mortality and hospital charges. Additional analyses using the coarsened exact matching algorithm were performed to assess the influence of insurance type in predicting outcomes. RESULTS: A data inquiry identified 103,290 shoulder replacement patients (68,578 Medicare, 27,159 private insurance, 3544 Medicaid/uninsured, 4009 other). The overall complication rate was 17.2% (n = 17,810) and the mortality rate was 0.20% (n = 208). Medicare and Medicaid/uninsured patients had a significantly higher rate of medical, surgical, and overall complications compared with private insurance using the controlled match data. Multivariate regression analysis found that having private insurance was associated with fewer overall medical complications. CONCLUSION: Private insurance payer status is associated with a lower risk of perioperative medical and surgical complications compared with an age- and sex-matched Medicare and Medicaid/uninsured payer status. Mortality was not statistically associated with payer status. Primary insurance payer status should be considered as an independent risk factor during preoperative risk stratification for shoulder arthroplasty procedures.

A comparison of preliminary oncologic outcome and postoperative complications between patients undergoing either open or robotic radical cystectomy.

PURPOSE: To compare complications and outcomes in patients undergoing either open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RRC). MATERIALS AND METHODS: We retrospectively identified patients that underwent ORC or RRC between 2003- 2013. We statistically compared preliminary oncologic outcomes of patients for each surgical modality. RESULTS: 92 (43.2%) and 121 (56.8%) patients underwent ORC and RRC, respectively. While operative time was shorter for ORC patients (403 vs. 508 min; p<0.001), surgical blood loss and transfusion rates were significantly lower in RRC patients (p<0.001 and 0.006). Length of stay was not different between groups (p=0.221). There was no difference in the proportion of lymph node-positive patients between groups. However, RRC patients had a greater number of lymph nodes removed during surgery (18 vs. 11.5; p<0.001). There was no significant difference in the incidence of pre-existing comorbidities or in the Clavien distribution of complications between groups. ORC and RRC patients were followed for a median of 1.38 (0.55-2.7) and 1.40 (0.58-2.59) years, respectively (p=0.850). During this period, a lower proportion (22.3%) of RRC patients experienced disease recurrence vs. ORC patients (34.8%). However, there was no significant difference in time to recurrence between groups. While ORC was associated with a higher all-cause mortality rate (p=0.049), there was no significant difference in disease-free survival time between groups. CONCLUSIONS: ORC and RRC patients experience postoperative complications of similar rates and severity. However, RRC may offer indirect benefits via reduced surgical blood loss and need for transfusion.

A comparison of preliminary oncologic outcome and postoperative complications between patients undergoing either open or robotic radical cystectomy

ABSTRACT Purpose: To compare complications and outcomes in patients undergoing either open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RRC). Materials and Methods: We retrospectively identified patients that underwent ORC or RRC between 2003- 2013. We statistically compared preliminary oncologic outcomes of patients for each surgical modality. Results: 92 (43.2%) and 121 (56.8%) patients underwent ORC and RRC, respectively. While operative time was shorter for ORC patients (403 vs. 508 min; p<0.001), surgical blood loss and transfusion rates were significantly lower in RRC patients (p<0.001 and 0.006). Length of stay was not different between groups (p=0.221). There was no difference in the proportion of lymph node-positive patients between groups. However, RRC patients had a greater number of lymph nodes removed during surgery (18 vs. 11.5; p<0.001). There was no significant difference in the incidence of pre-existing comorbidities or in the Clavien distribution of complications between groups. ORC and RRC patients were followed for a median of 1.38 (0.55-2.7) and 1.40 (0.582.59) years, respectively (p=0.850). During this period, a lower proportion (22.3%) of RRC patients experienced disease recurrence vs. ORC patients (34.8%). However, there was no significant difference in time to recurrence between groups. While ORC was associated with a higher all-cause mortality rate (p=0.049), there was no significant difference in disease-free survival time between groups. Conclusions: ORC and RRC patients experience postoperative complications of similar rates and severity. However, RRC may offer indirect benefits via reduced surgical blood loss and need for transfusion.
