Percutaneous Ultrasound-Guided Coracohumeral Ligament Release for Refractory Adhesive Capsulitis: A Prospective, Randomized, Controlled, Crossover Trial Demonstrating One-Year Efficacy.

BACKGROUND: Adhesive capsulitis (AC) is a painful and disabling condition with restricted range of motion (ROM) that affects 2% to 3% of the population and up to 20% of patients with diabetes. AC can be idiopathic, iatrogenic, or secondary to shoulder injuries. Some associated conditions include diabetes mellitus, thyroid disorders, dyslipidemia, stroke, prolonged immobilization, and autoimmune conditions. Management ranges from analgesics to physical therapy, local injections, hydrodilatation, and advanced surgical interventions. This study examines percutaneous coracohumeral ligament (PCHL) sectioning with the hypothesis that interruption would improve pain and ROM in patients with AC refractory to conservative management. OBJECTIVES: To use sonographically guided percutaneous interruption of the CHL for the treatment of refractory AC. STUDY DESIGN: A prospective, randomized, controlled, cross-over trial. SETTING: Academic medical center. METHODS: Patients were identified based on inclusion and exclusion criteria under the supervision of the Principal Investigator. After primary screening, research staff explained the study, risks, and benefits to the patients, and consent was obtained. Patients' pain score and shoulder ROM were assessed before and after the procedure, at one month, and one year. The Oxford Shoulder Scoring (OSS) questionnaire was also completed before the procedure and in the one-year follow-up visit.Forty patients were enrolled with refractory AC. Forty-six shoulders were treated; 6 patients underwent a bilateral procedure. Block 2:1 randomization was performed for the 2 groups (PCHL release [PCHLR] and local anesthetic CHL [LACHL]). The LACHL group received a lidocaine injection at CHL, and the PCHLR group received the CHL using a Tenex® (Tenex Health, Lake Forest, CA) needle. ROM, Numeric Rating Scale (NRS-11), and OSS were evaluated at baseline, immediate postprocedure, and long term. RESULTS: Among 46 shoulders included in the study, 7 were excluded due to lost to follow-up, total shoulder replacement, and shoulder manipulation. Twenty-six were randomized to the PCHLR group and 13 to LACHL group. ROM (external rotation and abduction), pain, NRS-11 score, and OSS score were measured at baseline and long term, confirmed by a nonbiased health care personnel. There was no statistically significant difference in ROM, NRS-11, and OSS between the 2 cohorts at the baseline visit. Nine patients in LACHL group crossed over to the PCHLR arm at one month. Data analysis in the long term revealed durability of the PCHLR group with a statistically significant difference in ROM, NRS-11, and OSS. External rotation improved by double, and abduction improved by almost 30% (P value < .001). NRS-11 decreased from 8 (IQR 8, 9) at baseline to 3 (IQR 2, 7) at long term among those who received PCHLR. The baseline mean OSS in the PCHLR group increased from 7.44 to 31.86 at one-year follow-up and was statistically significant (P value < .001). LIMITATIONS: This study represents a small population of patients with a CHL-related ROM deficit. Patients were not excluded for osteoarthritis or other motion-disabling shoulder conditions. We submit that the strength of the study could have been improved if the physician performing the procedure was blinded and if the patient was blinded as well to minimize operator and patient bias. CONCLUSIONS: We demonstrate that our technique for PCHLR is a safe, effective, and durable procedure that improved ROM, pain, and shoulder function in our patient population when compared to the control. KEY WORDS: Tenex, frozen shoulder, pain, range of motion, function, shoulder, minimally invasive, durable.

Percutaneous Ultrasound-Guided Tenotomy of the Iliotibial Band for Trochanteric Pain Syndrome: A Longitudinal Observational Study With One-Year Durability Results.

BACKGROUND: Upper lateral hip pain is a common complaint in adults and is referred to as greater trochanteric pain syndrome (GTPS) and is more prevalent among older women. This is a debilitating condition that could result in lower physical activity and quality of life, and higher unemployment rate. GTPS is a clinical diagnosis, and many cases improve with conservative medical management (CMM). However, there is still a gap between patients not responding to CMM and those who are not good surgical candidates. Thus, percutaneous ultrasound tenotomy (PUT) may be a valuable treatment option to limit this gap. OBJECTIVES: Demonstration of the one-year pain and functional outcomes, including sit to stand. SETTING: Academic tertiary care medical center. METHODS: Forty-eight consecutive patients with refractory trochanteric pain due to iliotibial band (ITB) tendinopathy. Fifty-six hips were treated; 8 patients underwent bilateral procedures. Electronic medical record review of consecutive patients who underwent ITB TENEX® was performed at Montefiore Medical Center from December 2019 to December 2021. Institutional guidelines recommended TENEX® for greater trochanteric pain refractory to conservative treatment and ultrasound (US) confirmed ITB tendinopathy (hypoechogenicity or thickened tendon > 6 mm). Pain level, as well as sit-to-stand, side-lying, and walking tolerance levels were evaluated at baseline preprocedure visit and one-year visit. Follow-up was performed by independent practitioners and corroborated by chart review. RESULTS: Numeric Rating Scale (NRS-11) improved by 4 points across all patients. Seventy percent of patients endorsed pain relief at one-year visit. Median preprocedure NRS-11 was 9. The reported median NRS-11at one year was 5 (Wilcoxon signed rank NRS-11 demonstrated a Z score of -6.042 with P < 0.001). One-year analysis among all patients revealed 57%, 78%, and 66% improvement in side-lying, sit-to-stand, and walking tolerance levels, respectively. LIMITATIONS: We believe that our results must be confirmed with a randomized control trial with a control arm and more patients included. CONCLUSIONS: PUT of the ITB using the TENEX® tissue remodeling device could be a safe and effective treatment for ITB tendinopathy-associated GTPS.

Rehabilitation and In-Hospital Mortality in COVID-19 Patients.

BACKGROUND: Coronavirus disease 2019 (COVID-19) guidelines endorse early rehabilitation to improve outcomes in hospitalized patients, but the evidence base to support this recommendation is lacking. We examined the association between early rehabilitation and in-hospital deaths in COVID-19 patients. METHOD: A single-center retrospective study, involving 990 COVID-19 patients (42.4% women, mean age 67.8 years) admitted between March 1, 2020 and May 31, 2020 to a community hospital, was conducted. Association of rehabilitation during hospitalization with in-hospital mortality was examined using logistic regression analysis adjusted for demographics, length of stay, body mass index, comorbid illnesses, functional status as well as for COVID-19 presentations, treatments, and complications. RESULTS: Over the 3-month study period, 475 (48.0%) inpatients were referred for rehabilitation. Patients who received rehabilitation were older (73.7 ± 14.0 vs 62.3 ± 17.2). There were 61 hospital deaths (12.8%) in the rehabilitation group and 165 (32.0%) in the nonrehabilitation group. Receiving rehabilitation was associated with an 89% lower in-hospital mortality (odds ratio [OR]: 0.11, 95% confidence interval [CI]: 0.06-0.19) after adjusting for multiple confounders and COVID-19 disease markers. In sensitivity analyses, the results were significant in subpopulations defined by age group, sex, race, length of hospitalization, or pulmonary presentations. Each additional rehabilitation session was associated with a 29% lower risk of in-hospital mortality (OR per session: 0.71, 95% CI: 0.64-0.79) in the fully adjusted model. CONCLUSION: Among hospitalized COVID-19 patients, receiving early rehabilitation was associated with lower in-hospital mortality. Our findings support implementation of rehabilitation services for COVID-19 patients in acute care settings, but further research from randomized clinical trials is needed.

Sonographically Guided Percutaneous Sectioning of the Coracohumeral Ligament for the Treatment of Refractory Adhesive Capsulitis: Proof of Concept.

INTRODUCTION: Treatment options are limited for nonsurgical chronic refractory cases of adhesive capsulitis. We describe a novel percutaneous tenotomy technique for coracohumeral ligament interruption with cadaveric validation. OBJECTIVE: The objective of this study was to describe and validate a novel technique for percutaneous interruption of the coracohumeral ligament. DESIGN: Cadaveric study. SETTING: Academic tertiary care center. METHODS: Eight cadavers underwent ultrasound (US)-guided percutaneous incision of the coracohumeral (CHL) ligament. Performance of the procedure requires that the practitioner make oscillatory motions with a needle that uses ultrasound energy to cut through tissue. Each pass removes a pinhead-sized amount of tissue. The number of passes and the cutting time are recorded during the procedure. As a standard for this procedure does not exist, the authors created their own based on the preclinical information presented here. Postprocedure dissection was performed to assess the extent of CHL interruption and injury to surrounding tissue. RESULTS: The average resection time was seven minutes, requiring 500 passes. The technique described in this paper completely interrupted the CHL in all subjects. Cadaveric analysis demonstrated interruption of the CHL with respect to control shoulders requiring an average of seven minutes of cutting time and ∼500 micro-perforations. CONCLUSION: US-guided percutaneous CHL ligament sectioning is possible with a commercially available ultrasonic probe.

Telemedicine During COVID-19 and Beyond: A Practical Guide and Best Practices Multidisciplinary Approach for the Orthopedic and Neurologic Pain Physical Examination.

BACKGROUND: The COVID pandemic has impacted almost every aspect of human interaction, causing global changes in financial, health care, and social environments for the foreseeable future. More than 1.3 million of the 4 million cases of COVID-19 confirmed globally as of May 2020 have been identified in the United States, testing the capacity and resilience of our hospitals and health care workers. The impacts of the ongoing pandemic, caused by a novel strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have far-reaching implications for the future of our health care system and how we deliver routine care to patients. The adoption of social distancing during this pandemic has demonstrated efficacy in controlling the spread of this virus and has been the only proven means of infection control thus far. Social distancing has prompted hospital closures and the reduction of all non-COVID clinical visits, causing widespread financial despair to many outpatient centers. However, the need to treat patients for non-COVID problems remains important despite this pandemic, as care must continue to be delivered to patients despite their ability or desire to report to outpatient centers for their general care. Our national health care system has realized this need and has incentivized providers to adopt distance-based care in the form of telemedicine and video medicine visits. Many institutions have since incorporated these into their practices without financial penalty because of Medicare's 1135 waiver, which currently reimburses telemedicine at the same rate as evaluation and management codes (E/M Codes). Although the financial burden has been alleviated by this policy, the practitioner remains accountable for providing proper assessment with this new modality of health care delivery. This is a challenge for most physicians, so our team of national experts has created a reference guide for musculoskeletal and neurologic examination selection to retrofit into the telemedicine experience. OBJECTIVES: To describe and illustrate musculoskeletal and neurologic examination techniques that can be used effectively in telemedicine. STUDY DESIGN: Consensus-based multispecialty guidelines. SETTING: Tertiary care center. METHODS: Literature review of the neck, shoulder, elbow, wrist, hand, lumbar, hip, and knee physical examinations were performed. A multidisciplinary team comprised of physical medicine and rehabilitation, orthopedics, rheumatology, neurology, and anesthesia experts evaluated each examination and provided consensus opinion to select the examinations most appropriate for telemedicine evaluation. The team also provided consensus opinion on how to modify some examinations to incorporate into a nonhealth care office setting. RESULTS: Sixty-nine examinations were selected by the consensus team. Household objects were identified that modified standard and validated examinations, which could facilitate the examinations.The consensus review team did not believe that the modified tests altered the validity of the standardized tests. LIMITATIONS: Examinations selected are not validated for telemedicine. Qualitative and quantitative analyses were not performed. CONCLUSIONS: The physical examination is an essential component for sound clinical judgment and patient care planning. The physical examinations described in this manuscript provide a comprehensive framework for the musculoskeletal and neurologic examination, which has been vetted by a committee of national experts for incorporation into the telemedicine evaluation.

Use of a Screening Questionnaire to Identify Patients at Risk of Hyperglycemia Prior to Steroid Injection Therapy.

Objective: Patients with chronic pain considered for steroid injections are not consistently screened for undiagnosed or poorly controlled diabetes mellitus (DM) prior to steroid administration despite the known impact of corticosteroids on glucose control. A quality improvement project was undertaken to identify the prevalence of at-risk patients prior to steroid exposure through the development and implementation of a screening questionnaire. Subject: Three hundred and five adult patients with chronic pain who were being considered for an outpatient steroid injection were interviewed. Methods: Each patient was asked to complete an American Diabetes Association-validated diabetes mellitus screening questionnaire (ADAQ). In addition, patients responded to a set of nine questions that addressed common signs and symptoms of hyperglycemia. Results: The total prevalence of known DM in the study population was found to be 20% (60 patients), based on a documented history of diabetes mellitus. The ADAQ identified an additional 135 patients (45%) at high risk for undiagnosed DM. The full study questionnaire identified 143 patients (47.3%) who had no known history of diabetes mellitus as being at risk for hyperglycemia. In patients with known diabetes, five of nine symptom-based screening questions occurred with significantly frequency (P < 0.05): excessive thirst, excessive hunger, blurred vision, poor wound healing, and repeated infections. Conclusions: More than 60% of the patients screened had high risk of having inadequately treated DM. Thus, routine screening for DM should be considered in patients prior to treatment involving corticosteroids. The study questionnaire is a potentially cost-effective initial screening tool to determine which patients should undergo laboratory testing.

Safety profile of intraoperative methadone for analgesia after major spine surgery: An observational study of 1,478 patients.

OBJECTIVE: To investigate the incidence of perioperative adverse events in patients receiving intravenous methadone for major spine surgery. DESIGN: Retrospective review of perioperative records from March 2011 and February 2016. SETTING: University of Virginia Healthsystem. PATIENTS: Adult patients undergoing elective spinal fusion of two or more levels. MAIN OUTCOME MEASURES: Incidence of respiratory depression, time to extubation, hypotension, hypoxemia, reintubation, cardiac complications, and death. RESULTS: Reviewed 1,478 patient records. Mean intraoperative methadone dose was 0.14 ± 0.07 mg/kg. A total of 1,142 patients (77.4 percent) were extubated in the operating room, 543 (36.8 percent) experienced respiratory depression, 1,180 (79.8 percent) hypoxemia, and 22 (1.5 percent) required reintubation. Cardiac complications included arrhythmias (289 patients, 29.9 percent), QTc prolongation (568 patients, 58.8 percent), and myocardial infarction (16 patients, 1.1 percent). Two in hospital deaths occurred (0.14 percent). CONCLUSIONS: Mild-moderate respiratory depression is observed following a one-time dose of intraoperative methadone, and monitoring in an appropriate postoperative setting is recommended.

Incidence and Risk Factors for Chronic Postoperative Opioid Use After Major Spine Surgery: A Cross-Sectional Study With Longitudinal Outcome.

BACKGROUND: Chronic opioid use is a significant public health concern. Surgery is a risk factor for developing chronic opioid use. Patients undergoing major spine surgery frequently are prescribed opioids preoperatively and may be at risk for chronic opioid use postoperatively. The aim of this study was to investigate the incidence of and perioperative risk factors associated with chronic opioid use after major spine surgery. METHODS: The records of patients who underwent elective major spine surgery at the University of Virginia between March 2011 and February 2016 were retrospectively reviewed. The primary outcome was chronic opioid use through 12 months postoperatively. Demographic data, medical comorbidities, preoperative pain scores, and medication use including daily morphine-equivalent (ME) dose, intraoperative use of lidocaine and ketamine, estimated blood loss, postoperative pain scores and medication use, and postoperative opioid use were collected. Logistic regression models were used to examine factors associated with chronic opioid use. RESULTS: Of 1477 patient records reviewed, 412 patients (27.9%) were opioid naive and 1065 patients (72.3%) used opioids before surgery. Opioid data were available for 1325 patients, while 152 patients were lost to 12-month follow-up and were excluded. Of 958 preoperative opioid users, 498 (52.0%) remained chronic users through 12 months. There was a decrease in opioid dosage (mg ME) from preoperative to 12 months postoperatively with a mean difference of -14.7 mg ME (standard deviation, 1.57; 95% confidence interval [CI], -17.8 to -11.7). Among 367 previously opioid-naive patients, 67 (18.3%) became chronic opioid users. Factors associated with chronic opioid use were examined using logistic regression models. Preoperative opioid users were nearly 4 times more likely to be chronic opioid users through 12 months than were opioid-naive patients (odds ratio, 3.95; 95% CI, 2.51-6.33; P < .001). Mean postoperative pain score (0-10) was associated with increased odds of chronic opioid use (odds ratio for a 1 unit increase in pain score 1.25, 95% CI, 1.13-1.38; P < .001). Use of intravenous ketamine or lidocaine was not associated with chronic opioid use through 12 months. CONCLUSIONS: Greater than 70% of patients presenting for major spine surgery used opioids preoperatively. Preoperative opioid use and higher postoperative pain scores were associated with chronic opioid use through 12 months. Use of ketamine and lidocaine did not decrease the risk for chronic opioid use. Surveillance of patients for these factors may identify those at highest risk for chronic opioid use and target them for intervention and reduction strategies.

Case report of a computerized tomography sign in Strongyloides stercoralis infection.

This is a case of strongyloidiasis showing colon enhancement on a computerized tomography (CT) scan. The patient presented with chief complaints of diarrhea and abdominal pain. She gave a history of recent travel to El Salvador and her stool was positive for Strongyloides stercoralis. A CT scan revealed a circumferential enhancement of the sigmoid colon. This CT sign was unusual in strongyloidiasis and when combined with the symptoms, caused us to rule out inflammatory bowel disease and shock bowel. Stool examination revealed ova and parasites of Strongyloides stercoralis. She was then treated with ivermectin which resulted in resolution of her symptoms.

A review and survey of policies utilized for interventional pain procedures: a need for consensus.

BACKGROUND: Other than the newly published anticoagulation guidelines, there are currently few recommendations to assist pain medicine physicians in determining the safety parameters to follow when performing interventional pain procedures. Little information exists regarding policies for oral intake, cumulative steroid dose limits, driving restrictions with and without sedation, and routine medication use for interventional procedures. METHODS: A 16-question survey was developed on common policies currently in use for interventional pain procedures. The questionnaire was distributed through the American Society of Regional Anesthesia and Pain Medicine and American Academy of Pain Medicine. We sought to statistically analyze the range of policies being used by pain medicine physicians and to determine if there are any commonly accepted standards. RESULTS: A total of 337 physicians out of 4037 members responded to our survey with a response rate of 8.4%. A total of 82% of these respondents used a sedative agent while performing an interventional pain procedure. The majority of respondents required drivers after procedures, except after trigger points. A total of 47% indicated that they have an nil per os (NPO) policy for procedures without sedation. A total of 98% reported that they had an anticoagulation policy before an interventional procedure. A total of 17% indicated that the interval between steroid doses was <2 weeks, while 53% indicated that they waited 2-4 weeks between steroid doses. CONCLUSION: Our study has clearly demonstrated a wide variation in the current practice among physicians regarding sedation, NPO status, steroid administration, and the need for designated drivers. There was much higher endorsement of policies regarding anticoagulation. There is an obvious need for evidence-based guidelines for these aspects of interventional pain care to improve patient safety and minimize the risk of adverse events.

Retrospective case-control non-inferiority analysis of intravenous lidocaine in a colorectal surgery enhanced recovery program.

BACKGROUND: Enhanced recovery after surgery (ERAS) programs typically utilizes multi-modal analgesia to reduce perioperative opioid consumption. Systemic lidocaine is used in several of these ERAS algorithms and has been shown to reduce opioid use after colorectal surgery. However it is unclear how much the other components of an ERAS protocol contribute to the final outcome. Using a noninferiority analysis we sought to assess the role of perioperative lidocaine in an ERAS program for colorectal surgery, using pain and opioid consumption as outcomes. METHODS: We conducted a retrospective review of patients who had received intravenous lidocaine perioperatively during colorectal surgery. We matched them with patients who were managed using a multi-component ERAS protocol, which included perioperative lidocaine. We tested a joint hypothesis of noninferiority of lidocaine infusion to ERAS protocol in postoperative pain scores and opioid consumption. We assigned a noninferiority margin of 1 point (on an 11-point numerical rating scale) difference in pain and a ratio [mean (lidocaine) / mean (ERAS)] of 1.2 in opioid consumption, respectively. RESULTS: Fifty-two patients in the lidocaine group were matched with patients in the ERAS group. With regards to opioid consumption, in the overall [1.68 (1.43-1.98)] [odds ratio (95% confidence interval)] analysis and on postoperative day (POD) 1 [2.38 (1.74-3.31)] lidocaine alone was inferior to multi-modal analgesia. On POD 2 and beyond, although the mean odds ratio for opioid consumption was 1.43 [1.43 (1.17-1.73)], the lower limit extended beyond the pre-defined cut-off of 1.2, rendering the outcome inconclusive. For pain scores lidocaine is non-inferior to ERAS [-0.17 (-1.08-0.74)] on POD 2 and beyond. Pain scores on POD 1 and in the overall cohort were inconclusive based on the noninferiority analysis. CONCLUSIONS: The addition of a multi-component ERAS protocol to intravenous lidocaine incrementally reduces opioid consumption, most evident on POD 1. For pain scores the data is inconclusive on POD 1, however on POD 2 and beyond lidocaine alone is non-inferior to an ERAS program with lidocaine. Opioid-related complications, including return of bowel function, were not different between the groups despite reduced opioid use in the ERAS group.

Case report of atypical Still's disease: a diagnosis of exclusion.

INTRODUCTION: We present an unusual presentation of a 39-year-old man with myalgias and shortness of breath. CHIEF COMPLAINTS: The patient presented to the emergency department with complaints of myalgias, shortness of breath and palpitations. During this hospitalization, he had multiple episodes of tachycardia and desaturation. The patient had elevated troponins and creatinine kinase. Differential diagnosis included pericarditis, pneumonia and malignancy. INVESTIGATIONS: The patient had elevated ferritin and erythrocyte sedimentation rate. OUTCOME: The patient had adult Still's disease. LESSON: This case shows how the presentation and symptom complex of Still's disease together with the lack of specific serological markers can misguide the diagnosis.
