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.

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.

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.

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.

Distal biceps repair using the lacertus fibrosus as a local graft.

BACKGROUND: We report a case series of 15 patients who underwent a new surgical technique that uses a transfer of the lacertus fibrosus to augment the repair of the distal biceps tendon. This technique seeks to minimize the need for and potential complications associated with autogenous or allograft tendon reconstruction in this clinical scenario. METHODS: We reviewed the clinical outcomes of patients who both underwent a lacertus transfer for biceps tendon reconstruction during a 10-year period and had at least 6 months of follow-up. Their clinical outcomes, including success of tendon repair, functional performance, and associated surgical complications, were evaluated. RESULTS: During a 10-year period, 244 patients underwent surgery for repair or reconstruction of the distal biceps tendon. During this time, 15 patients met the criteria for use of the lacertus transfer technique. When direct repair was not possible because of tendon retraction and attrition, although a tendon graft was considered, the intact lacertus fibrosus was used to augment the biceps repair. Of these 15 patients, 12 met study inclusion criteria. At latest follow-up, all 12 patients were successfully treated by the lacertus transfer without complication, had regained elbow flexion and forearm supination strength, and had no lacertus harvest complications. CONCLUSIONS: When operative treatment is chosen for biceps tendon injuries and if the lacertus fibrosus is intact, transfer of the lacertus to augment repair of the distal biceps provides predictable outcomes without the potential complications associated with allograft or autograft tendon reconstruction.

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.

Weighted Gleason scores do not outperform standard clinical Gleason scores.

INTRODUCTION: Predicting patient survival rates following radical prostatectomy remains an area of clinical interest. We compared the ability of standard clinical Gleason scores and alternative 'weighted' Gleason scores to predict pathology, margin status and recurrence in prostate cancer. MATERIALS AND METHODS: Patients who underwent robotic radical prostatectomy performed by a single surgeon between Jan 2007 - Dec 2008 were included. Tumor at the inked margin in pathologic samples was considered a positive margin. Recurrence was defined as PSA ≥ 0.2 or the institution of salvage therapy. Standard pathologic Gleason scores were recorded. The proportion of tumor in each core was used to calculate 'weighted' and 'rounded weighted ' Gleason scores. The ability of each Gleason score to predict pathology, margin status and recurrence were statistically compared. RESULTS: Of 433 cases, 281 with uniform Gleason 6 cores were excluded. One hundred and fifty-two cases had Gleason scores ≥ 7, of which complete data were unavailable for three patients. In the final cohort of 149 cases, 72 (48.3%) patients had uniformly scored biopsies, while 77 (51.7%) had biopsies with non-uniform Gleason scores. The positive margin rate and recurrence free rates were 30.2% and 77.2%, respectively. Analyses of the entire patient cohort, and patients with non-uniform cores, found no significant difference between the predictive capacities of each scoring system. The alternative algorithms were not shown to be better predictors of pathologic Gleason score, margin status or recurrence. CONCLUSIONS: Using the highest standard Gleason score of all cores to define a preoperative Gleason score remains an appropriate clinical practice.

Surgical complications associated with robotic urologic procedures in elderly patients.

INTRODUCTION: Urologic malignancies are often diagnosed at an older age, and are increasingly managed utilizing robotic-assisted surgical techniques. As such, we assessed and compared peri-postoperative complication rates following robotic urologic surgery in elderly and younger patients. MATERIALS AND METHODS: A retrospective analysis of IRB-approved databases and electronic medical records identified patients who underwent robotic-assisted urologic surgery between December 2003-September 2013. Patients were grouped according to surgical procedure (partial nephrectomy, radical cystectomy, radical prostatectomy) and age at surgery (≤ 74 or ≥ 75 years old). Associations between age, comorbidities, Charlson comorbidity index (CCI), and patient outcomes were evaluated within each surgery type. RESULTS: 97.5% and 2.5% of patients were ≤ 74 or ≥ 75 years old, respectively. Cystectomies, partial nephrectomies and prostatectomies accounted for 3.5%, 9.5% and 87.1% of surgeries, respectively. Within cystectomy, nephrectomy and prostatectomy groups, 24.4%, 12.5% and 0.6% patients were ≥ 75 years old. Within each surgical type, elderly patients had significantly elevated CCI scores. Length of stay was significantly prolonged in elderly patients undergoing partial nephrectomy or prostatectomy. In elderly cystectomy, partial nephrectomy and prostatectomy patients, 36.7%, 14.3% and 5.9% suffered ≥ 1 Clavien grade 3-5 complication, respectively. Major complications were not significantly different between age groups. A qualitatively similar pattern was observed regarding Clavien grade 1-2 complications. CONCLUSIONS: The risks of robotic-assisted urologic surgery in elderly patients are not significantly elevated compared to younger patients.

Are Preexisting Retinal and Central Nervous System-Related Comorbidities Risk Factors for Complications Following Robotic-Assisted Laparoscopic Prostatectomy?

PURPOSE: To assess whether retinal and central nervous system (CNS) comorbidities are risk factors for complications following robotic assisted laparoscopic prostatectomy (RALP). MATERIALS AND METHODS: A retrospective review of our RALP database identified 1868 patients who underwent RALP by a single surgeon between December 10, 2003-March 14, 2014. We hypothesized that patients with preexisting retinal or CNS comorbidities were at a greater risk of suffering retinal and CNS complications following RALP. Perioperative complications and risk of recurrence were graded using the Clavien and D'Amico systems, respectively. RESULTS: 40 (2.1%) patients had retinal or CNS-related comorbidities, of which 15 had a history of retinal surgery and 24 had a history of cerebrovascular accident, aneurysm and/or neurosurgery. One additional patient had a history of both retinal and CNS events. Patients with retinal or CNS comorbidities were significantly older, had elevated PSA levels and CCI (Charlson Comorbidity Index) scores than the control group. Blood loss, length of stay, surgical duration, BMI, diagnostic Gleason score and T-stage were not statistically different between groups. No retinal or CNS complications occurred in either group. The distribution of patients between D'Amico risk categories was not statistically different between the groups. There was also no difference in the incidence of total complications between the groups. CONCLUSIONS: RALP-associated retinal and CNS complications are rare. While our RALP database is large, the cohort of patients with retinal or CNS-related comorbidities was relatively small. Our dataset suggests retinal and CNS pathology presents no greater risk of suffering from perioperative complications following RALP.

An unusually large leiomyoma of the prostate.

Prostate leiomyomas are benign mesenchymal smooth muscle tumors devoid of glandular elements within the prostate or juxta-prostatic position. Leiomyomas develop in organs containing smooth muscle, including the kidney, bladder and seminal vesicle. Prostate leiomyomas are either a pure form or associated with benign prostate hyperplasia, and diagnosis is challenging, with definitive identification relying on pathology. However, imaging techniques, such as MRI, have proven to be useful diagnostic tools. We report on a 57-year-old male with lower urinary tract symptomatology who was diagnosed with a large prostate leiomyoma and underwent an open radical cystoprostatectomy and ileal conduit urinary diversion.

Clinical and radiographic characteristics governing the selection of therapy of small renal masses.

INTRODUCTION: Renal masses are commonly managed by partial nephrectomy (PN) or active surveillance (AS). We assessed the impact of patient demographics and clinical indices in determining treatment decisions of renal masses between these two options. MATERIALS AND METHODS: We retrospectively reviewed our renal mass database to retrieve demographic and clinical records of patients who underwent immediate PN or entered a >= 12 month period of AS during February 1999 to May 2014. Age, gender, body mass index (BMI), Charlson Comorbidity Index (CCI) score, follow up time, tumor size, tumor location, renal invasion, creatinine, and estimated glomerular filtration rate (eGFR) were assessed as predictors of the selected treatment option. RESULTS: Seven hundred thirty-five patients with 744 renal masses underwent immediate PN, while 123 patients with 140 renal masses entered active surveillance. PN patients were predominantly male, younger, had elevated BMI, lower CCI scores, elevated eGFR and had larger tumors that invaded further into the renal collecting system. Renal masses in men were more likely to be treated by PN, while patients categorized as overweight or obese were 2-3 fold more likely to have their renal mass being manage by PN (versus patients with BMI in the normal range). Higher CCI scores were associated with a renal mass being more likely to be treated by AS, while increased renal mass size was associated with decisions to treat with PN. Compared to cortical location, renal masses abutting the renal collecting system were more likely to be treated by PN. CONCLUSIONS: Gender, BMI, CCI, tumor size, and tumor invasion into the renal system are useful predictors of renal mass treatment.

Active surveillance of renal masses: an analysis of growth kinetics and clinical outcomes stratified by radiological characteristics at diagnosis.

AIMS: To determine the growth rate of renal masses (RMs) under active surveillance (AS), and to describe the clinical outcome of AS patients. MATERIALS AND METHODS: We conducted a retrospective review of an AS database to obtain demographics, radiological and pathologic characteristics and RM size of patients. RMs were followed at 6-12 month intervals for ≥1 year with computed tomography (CT), magnetic resonance imaging (MRI), or renal ultrasound. Kaplan-Meier analysis determined the annual likelihood of intervention. RMs were divided into 3 radiographic subcategories (solid, cystic, and angiomyolipoma). A linear regression model determined RM growth rates. RESULTS: 131 RMs in 114 patients were included. Median age, Charlson Comorbidity Index score and mean follow-up were 69.1 years, 4.0 and 4.2±2.6 years, respectively. Maximal tumor diameter (MTD) at diagnosis was 2.1 ± 1.3 cm. 49 RMs exhibited negative or zero net growth. Mean MTD growth rate for all RMs was 0.72±3.2 (95% CI: 0.16-1.28) mm/year. When stratified by MTD at diagnosis, mean RM growth rates were 0.84, 0.84, 0.44, 0.74 and 0.71 mm/year for RMs ≤1 cm, 1-≤2cm, 2-≤ 3cm, 3-≤ 4cm and ≥4cm, respectively (p≤0.01). The 5 and 10-year freedom from intervention rates were 93.1% and 88.5%, respectively. There was a single case of suspected metastases, but no deaths related to kidney cancer. CONCLUSIONS: RMs under AS grew slowly, and had a low incidence of requiring surgical intervention and progression. Solid enhancing masses grew slowly, and were more likely to trigger intervention. AS should be considered for selected patients with small RMs.

Team Approach: Diagnosis, Management, and Prevention of Sudden Cardiac Arrest in the Athlete.

¼ Sudden cardiac events during sports competition are rare but tragic occurrences that require a timely, comprehensive response by well-prepared athletic trainers and medical providers. This sequence should prioritize prompt emergency medical system activation, immediate initiation of cardiopulmonary resuscitation (CPR), automated early defibrillation (AED), and comprehensive advanced life support efforts.¼ Exercise-induced cardiac remodeling, referred to as the "athlete's heart," refers to a host of adaptive changes that increase cardiac chamber size and wall thickness to allow for greater pressures and volumes during exercise. This remodeling phenotype may overlap with other inherited cardiomyopathies and cardiac abnormalities, which can complicate clinical care. The long-term implications of this electrical and structural remodeling on cardiac function are unknown.¼ Although the best screening strategies to optimize primary prevention of sudden cardiac arrest is an evolving topic, the effectiveness of CPR and early defibrillation use in treating out-of-hospital sudden cardiac arrest has been well-established, despite their reported underuse.

Variations in the Anatomic Morphology of the Scapular Spine and Implications on Fracture After Reverse Shoulder Arthroplasty.

INTRODUCTION: This study evaluates the role of anatomic scapular morphology in acromion and scapular spine fracture (SSAF) risk after reverse shoulder arthroplasty (RSA). METHODS: Twelve scapular measurements were captured based on pilot study data, including scapular width measurements at the acromion (Z1), middle of the scapular spine (Z2), and medial to the first major angulation (Z3). Measurements were applied to 3D-CT scans from patients who sustained SSAF after RSA (SSAF group) and compared with those who did not (control group). Measurements were done by four investigators, and the intraclass correlation coefficient was calculated. Regression analysis determined trends in fracture incidence. RESULTS: One hundred forty-nine patients from two separate surgeons (J.L., A.M.) were matched by age and surgical indication of whom 51 sustained SSAF after reverse shoulder arthroplasty. Average ages for the SSAF and control cohorts were 78.6 and 72.1 years, respectively. Among the SSAF group, 15 were Levy type I, 26 Levy type II, and 10 Levy type 3 fractures. The intraclass correlation coefficient of Z1, Z2, and Z3 measurements was excellent (0.92, 0.92, and 0.94, respectively). Zone 1 and 3 measurements for the control group were 18.6 ± 3.7 mm and 3.2 ± 1.0 mm, respectively, compared with 22.5 ± 5.9 mm and 2.0 ± 0.70 mm in the SSAF group, respectively. The fracture group trended toward larger Z1 and smaller Z3 measurements. The average scapular spine proportion (SSP), Z1/Z3, was significantly greater in the control 6.20 ± 1.80 versus (12.60 ± 6.30; P < 0.05). Regression analysis showed a scapular spine proportion of ≤5 was associated with a fracture risk <5%, whereas an SSP of 9.2 correlated with a 50% fracture risk. DISCUSSION: Patients with a thicker acromions (Z1) and thinner medial scapular spines (Z3) have increased fracture risk. Understanding anatomic scapular morphology may allow for better identification of high-risk patients preoperatively.

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.

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.

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 Effect of the COVID-19 Pandemic on the Mental and Emotional Health of Athletes: A Systematic Review.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has caused the cancellation or postponement of virtually every sporting event, resulting in training disruptions, income loss, and career uncertainties for athletes around the world. At present, the effect of the COVID-19 pandemic on the mental and emotional health of athletes is not well understood. PURPOSE: To investigate the effect of the COVID-19 pandemic on the mental and emotional health of athletes and to identify risk factors associated with poor mental health outcomes. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: The PubMed, Embase, and Cochrane Library databases were searched to identify all articles reporting on athletes' mental and emotional health during the COVID-19 pandemic. Articles were selected based on relevant inclusion and exclusion criteria. Study characteristics, athlete demographics, and COVID-19 mental health data (sex-, type of sport-, and level of play-specific differences) were collected from each included article and analyzed. RESULTS: A total of 35 studies were included in the final analysis, comprising athletes around the world and across numerous sports and levels of play. Most studies utilized at least 1 validated mental health questionnaire and assessed for outcomes such as depression, anxiety, stress, motivation, and athletic identity. Overall, athletes reported worse mental and emotional health during the COVID-19 pandemic, although these effects were attenuated by home training programs and quarantine training camps. Female sex and more elite levels of play were associated with an increased risk for poor mental health outcomes. Type of sport was associated with mixed results, with individual and team sports carrying different increased risks for poor mental and emotional health. Nearly all studies recommended the need for increased psychological support of athletes during the COVID-19 pandemic. CONCLUSION: The effect of the COVID-19 pandemic on the mental and emotional health of athletes is complex and multifaceted. Increased social interactions with coaches and teammates, continued access to training facilities and mental health professionals, and active utilization of healthy coping mechanisms can improve mental health outcomes for athletes in the era of COVID-19.

The risk of COVID-19 transmission upon return to sport: a systematic review.

OBJECTIVES: To evaluate COVID-19 transmission rates in athletes upon return to sport (RTS), as well as the effectiveness of preventive and surveillance measures associated with RTS. METHODS: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the PubMed, Embase, and Cochrane Library databases were searched to identify all articles reporting on RTS during COVID-19. Articles were excluded on the basis of the following criteria: (1) non-English text, (2) only abstract available, (3) population not athlete-specific, (4) outcome not RTS-specific, (5) COVID-19 transmission data not quantified, (6) editorial, or (7) review article or meta-analysis. Study characteristics; athlete demographics; COVID-19 preventive, surveillance, and diagnostic measures; COVID-19 transmission outcomes; and RTS recommendations were collected from each included article and analyzed. RESULTS: 10 studies were included in the final analysis, comprising over 97,000 athletes across a wide variety of sports, levels of play, and RTS settings. Of the 10 studies, eight identified low transmission rates and considered RTS to be safe/low risk. Overall, COVID-19 transmission rates were higher in athletes than in contacts, and more prevalent in the greater community than in athletes specifically. The risk of COVID-19 did not appear to be necessarily higher for athletes who played high-contact team sports, shared common facilities, or lived in communities impacted by high transmission rates, provided that rigorous COVID-19 safety and testing protocols were implemented and followed. Mask wearing and physical distancing during active play presented the greatest challenge to athletes. CONCLUSION: Rigorous preventive and surveillance measures can mitigate the risk of COVID-19 transmission in athletes upon RTS. However, the heterogeneity of RTS playing conditions, availability of COVID-19 resources, rise of unforeseen novel variants, and undetermined long-term impact of vaccination on athletes remain a challenge to safe and effective RTS in the era of COVID-19.
