RESUMO

Background: Robotic-assisted orthopaedic surgery has become popular and widely available, mainly for total joint arthroplasty. However, there has been a persistent concern regarding access to robotic-assisted surgery and the utilization rate of total joint arthroplasty among minority groups. As an imperative effort to close the gap regarding health inequalities, we assessed the knowledge and perspective of Hispanics regarding robotic-assisted orthopaedic surgery. Methods: A 28-item questionnaire was established to evaluate Hispanics' perceptions of robotic-assisted orthopaedic surgery. Participants answered questions about demographic features, knowledge about robotic-assisted orthopaedic surgery, and preferences regarding manual vs robotic-assisted procedures. Results: A total of 580 questionnaires were analyzed in our study, with an average age of participants of 49.1 years. Only 44.2% of the participants were familiar with robotic-assisted orthopaedic surgery. Fifty-three percent of the respondents preferred robotic-assisted surgery over conventional procedures, with many participants believing that robotic-assisted surgery leads to better outcomes (54.7%) and faster recovery (53.1%). Conclusions: Knowledge about specific factors such as clinical outcomes and costs may influence the perception and preference of Hispanics toward robotic-assisted orthopaedic surgery. Therefore, patient education may play a crucial role in the informed decision-making process in Hispanics when opting between robotic-assisted or traditional orthopaedic surgery.

RESUMO

BACKGROUND: Spondylothoracic dysostosis (STD), also known as Jarcho-Levin syndrome (JLS), is a rare autosomal recessive disorder affecting the formation of the spine, characterized by a complete bilateral fusion of the ribs at the costovertebral junction, producing a "crablike" appearance of the thorax. Despite being declared a core indication for a V-osteotomy vertical expandable prosthetic titanium rib (VEPTR) expansion thoracoplasty of the posterior thorax, the natural history of STD in untreated subjects remains poorly documented. In this study, we report radiographic and pulmonary function findings and Patient-Reported Outcomes Measurement Information System (PROMIS) and 24-Item Early Onset Scoliosis Questionnaire (EOSQ-24) scores for untreated adult subjects with STD to gain insights into the natural history. METHODS: We identified 11 skeletally mature, untreated subjects with STD. Findings on medical evaluation, demographics, radiographic parameters, pulmonary function, genetic testing results, PROMIS measures, and EOSQ-24 scores were assessed. RESULTS: Five male and 6 female subjects (mean age, 32.3 years [range, 15 to 70 years]) with a confirmed STD diagnosis based on radiographs and genetic testing were evaluated. Mean body mass index (BMI) was 24.4 kg/m 2 (range, 18 to 38.9 kg/m 2 ), and mean thoracic height was 16 cm (range, 12 to 17 cm). Pulmonary function tests (PFTs) showed a mean forced vital capacity (FVC) of 22% of predicted, mean forced expiratory volume in 1 second (FEV1) of 24% of predicted, and FEV1/FVC ratio of 107% of predicted. The mean PROMIS dyspnea score was 40 ± 8 points (range, 27.7 to 52.1 points). The mean total EOSQ-24 score was 77.3 ± 18 points (range, 43.9 to 93.2 points). CONCLUSIONS: Our study characterizes the natural history of STD in untreated subjects. We confirmed the expected restrictive pattern in pulmonary function, but interestingly, our subjects exhibited better EOSQ scores compared with those reported in neuromuscular populations. PFT results and thoracic height did not correspond to PROMIS and EOSQ scores, questioning the use of those parameters as a surgical indication. We therefore suggest that the STD diagnosis as an absolute indication for VEPTR expansion thoracoplasty surgery be reconsidered. LEVEL OF EVIDENCE: Therapeutic Level IV .

RESUMO

Background Spastic joint contractures remain a complex and challenging condition. For patients with upper extremity spastic dysfunction, improving the muscle balance is essential to maximize their hand function. Multiple procedures, including proximal row carpectomy (PRC) and wrist arthrodesis (WA), are considered among the different surgical alternatives. However, the biomechanical consequences of these two procedures have not been well described in current literature. Hence, the objective of our study is to assess the change in the extrinsic digit flexor tendon resting length after proximal row carpectomy and wrist arthrodesis. Methods Six fresh-frozen cadaver upper extremities (four females and two males) with no obvious deformity underwent dissection, PRC, and WA. All the flexor digitorum profundus (FDP), flexor digitorum superficialis (FDS), and flexor pollicis longus (FPL) tendons were marked proximally 1-cm distal to their respective myotendinous junction and cut distally at the marked point. The overlapping segment of each distal flexor tendon from its proximal mark was considered the amount of flexor tendon resting length change after PRC and WA. A descriptive evaluation was performed to assess the increment in tendon resting length. Additionally, a regression analysis was performed to evaluate the relation between the tendon resting length and the proximal carpal row height. Results Following PRC and WA, the mean digit flexor tendon resting length increment achieved across all tendons was 1.88 cm (standard deviation [SD] = 0.45; range: 1.00-3.00 cm). A weak direct relationship ( R = 0.0334) between the increment in tendon resting length and proximal carpal row height was initially suggested, although no statistical significance was demonstrated ( p = 0.811). Conclusion This study provides an anatomic description of the increased extrinsic digit flexor tendon resting length after PRC and WA in cadaveric specimens. Findings provide a useful framework to estimate the amount of extrinsic digit flexor resting length increment achieved after wrist fusion and the proximal carpal row removal.

RESUMO

Evaluating the impact of surgical masks' conservation practices during the Coronavirus Disease pandemic in the bioburden of the operating room seems imperative, as they play a critical role against this pandemic. We demonstrate that surgeons' masks tend to be contaminated due to the conservation techniques to maximize protection equipment during the pandemic. Health institutions should highlight the importance of surgical mask exchange to avoid increments in surgical mask contamination.

RESUMO

Adequate pain control after total knee arthroplasty (TKA) has been associated with improved patient mobility and satisfaction, and is a task that has historically relied on opioids. Multimodal analgesic regimens can be considered a therapeutic alternative for postoperative pain control to avoid opioid consumption and its adverse side effects. This study aimed to evaluate the use of a multimodal analgesia protocol based on nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen as an alternative to reduce opioid consumption in Hispanic patients undergoing primary TKA. Methods: An institutional review board-approved, randomized controlled trial evaluated postoperative pain control after TKA in a Hispanic population. The experimental opioid-sparing group received 30-mg ketorolac intravenously every 6 hours and 1-g acetaminophen orally every 6 hours as the patient requested. The experimental group had the option to use morphine and oxycodone combined with acetaminophen as a rescue therapy. The control group received opioids in the form of 0.1-mg/kg morphine intravenously every 6 hours and/or oxycodone combined with acetaminophen (2.5 and 325 mg), 2 tablets orally every 6 hours, as the patient requested. Sociodemographic, operative, and immediate postoperative data and pain intensity measurements according to the numerical rating scale (NRS) were compared between groups. Analgesic efficacy was assessed according to the NRS scores at 12, 24, and 48 hours postoperatively. Results: Eighty-one Hispanic patients met inclusion criteria: 42 patients in the experimental group and 39 patients in the control group. None of the patients in the experimental group requested oxycodone combined with acetaminophen as a rescue therapy. Only 2 patients in the experimental group used a mean of 3.0 ± 1.4 mg of rescue morphine; in comparison, the control group consumed a mean of 28.0 ± 7.9 mg of morphine and 64.8 ± 26.0 mg of oxycodone per patient. A pain intensity decrease was observed in the experimental and control groups, with no postoperative evaluation differences at 12 hours (6.7 ± 2.9 compared with 5.9 ± 2.8; p = 0.209), 24 hours (6.2 ± 2.0 compared with 6.1 ± 2.2; p = 0.813), and 48 hours (4.7 ± 2.1 compared with 4.6 ± 1.7; p = 0.835). Conclusions: The use of a multimodal analgesic regimen based on intravenous ketorolac and oral acetaminophen was adequate in reducing postoperative pain and opioid consumption in Hispanic patients undergoing TKA. Level of Evidence: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Introduction: Pediatric back pain evaluation nowadays relies on patient history, physical examination, and plain radiographs to identify underlying pathologies. Constant pain, night pain, radicular pain, and abnormal neurological examination were previously recommended as clinical markers to assess the need for magnetic resonance imaging evaluation. Recent studies have challenged the use of these clinical markers, recommending further studies. This study aimed to assess pain intensity as a predictor of underlying magnetic resonance imaging pathology in children with back pain. Methods: An observational cross-sectional study of pediatric patients between 8 and 17 years with back pain for more than 4 weeks from 2009 to 2021 was conducted. A whole spine magnetic resonance imaging was performed on patients with back pain without an identifiable cause and no prior spine treatment. The numerical rating scale questionnaire was administered to each patient, and answers were divided into three groups: mild (1-3), moderate (4-6), and severe (7-10) numerical rating scale score. Student's t-test and chi-square analysis were used to correlate differences between continuous and categorical values, respectively. Results: Of 590 patients (70% female and a mean age of 15.25 years), there were 35.1% of patients had a magnetic resonance imaging underlying pathology. No association was found between severe numerical rating scale score and the presence of underlying MRI pathology (p = 0.666). Patients with low or moderate numerical rating scale scores had similar associations to an underlying magnetic resonance imaging pathology as patients with a severe numerical rating scale score (p = 0.256; p = 0.357, respectively). Conclusions: Back pain intensity was not found to be an effective clinical marker for predicting underlying magnetic resonance imaging pathology in pediatric patients with back pain.

RESUMO

BACKGROUND AND OBJECTIVES: Primary care physician shortage represents a challenge for many countries and territories, including Puerto Rico (PR), where a significant proportion of the graduating medical students preferred the continental United States (C-US) to complete their training and even as the definitive setting for their practice. We surveyed medical students who graduated from medical schools in PR and have been accepted in a residency program to evaluate the influence of a set of demographics, academic, and personal factors in their decision to pursue a primary care residency program in the C-US. METHODS: A 19-item questionnaire was distributed by institutional email to those medical students who graduated from one of the four Liaison Committee on Medical Education fully accredited medical schools in PR in 2019. We summarized our data by frequency and percentages. We performed data analysis with statistical significance considered for P values <.05. RESULTS: The questionnaire had a response rate of 51% (138/273), where 49% (67/138) were accepted in a primary care residency. Sixty percent (40/67) matched in a primary care program in the C-US. Among the evaluated factors, a prior degree in C-US (65%) and first-degree relatives living in the C-US (70%) were associated with students who matched in the mainland. First-degree relatives living in PR (96%) were associated with students who remained on the island for training. CONCLUSIONS: The results provide insight into the influence that personal factors have on the decision of medical students in PR to pursue primary care training in the C-US.

RESUMO

Early-onset scoliosis (EOS) is defined as any spinal deformity that is present before 10 years old, regardless of etiology. Deformity must be evaluated based on the intercorrelation between the lungs, spine, and thorax. Curvatures of early-onset have increased risk of progression, cardiorespiratory problems, and increased morbidity and mortality. Progression of the deformity may produce thoracic insufficiency syndrome, where a distorted thorax is unable to support normal respiratory function or lung growth. Management and treatment of EOS should pursue a holistic approach in which the psychological impact and quality of life of the patient are also taken into consideration. Growth-friendly surgical techniques have not met the initial expectations of correcting scoliotic deformity, promoting thoracic growth, and improving pulmonary function.

RESUMO

Desmoplastic fibroma is an extremely rare primary bone tumor that can mimic the presentation of other bone lesions. We describe the case of a middle-aged male with a mass on the left distal femur initially diagnosed as fibrous dysplasia that underwent a wide margin excision followed by a distal femoral replacement to restore anatomy and functionality. Histologic examination of the complete surgical specimen was consistent with a desmoplastic fibroma. This case is the first report of a successful application of endoprosthetic reconstruction after desmoplastic fibroma resection.

RESUMO

Background: There are limited data regarding the gender preferences of Hispanic Americans when selecting their orthopedic surgeon. This study aimed to evaluate the gender preferences of Hispanic Americans when choosing a physician as their orthopedic provider. Materials and Methods: A cross-sectional survey was administered to all consecutive Hispanic American patients treated at the outpatient orthopedic clinics of a tertiary medical center in Puerto Rico between October 4, 2019 and March 4, 2020. Sociodemographic status and opinion of gender preference in orthopedic surgery were assessed and analyzed between female and male respondents. Results: A total of 628 surveys were completed. There were 343 (54.6%) females and 285 (45.4%) males with an average age of 51.0 ± 13.0 years. A significantly higher portion of female respondents was widowed (p = 0.01), had a higher educational level (p = 0.02), were unemployed (p = 0.01), and had a lower individual annual income salary (p = 0.04); when compared with males. Most of the respondents had no gender preference (91.1% = 572/628) for an orthopedic provider. Among those with a gender preference, 5.1% (32/628) preferred a male surgeon, and 3.8% (24/628) preferred a female surgeon. No significant difference was found between male and female respondents in the opinion of an orthopedic provider. Conclusions: This study illustrates that Hispanic Americans have no gender preference when choosing an orthopedic provider. Therefore, patient preference should not be considered a factor contributing to women's under-representation in our orthopedic surgery training program. Our findings may also assist future studies in search of other indications attributed to the under-representation of females in this field.

RESUMO

PURPOSE: Hurricane Maria is the most devastating natural phenomenon in the recent history of Puerto Rico. Due to its destructive path through the island, the Puerto Rico Trauma Center (PRTC) remained the only hospital managing orthopaedic trauma in the immediate post-disaster period. We investigated the impact of this hurricane on the orthopaedic trauma epidemiology in the PRTC. METHODS: We evaluated the admissions by the orthopaedic surgery service in terms of demographics, mechanisms of injury, and orthopaedic diagnoses for two months after the impact of Hurricane Maria (HM) on September 20, 2017. We compared our study group with the same two month period for two years prior (2015 and 2016) and after (2018 and 2019) as control periods. A p value of < 0.05 was considered statistically significant. RESULTS: We included 384 admissions from September 20 to November 20, 2017. The majority were males (63%) and had an average age of 54 years. The most-reported mechanism of injury was fall from standing height (FFSH), showing a significant increment compared with the control periods. Contrarily, motor vehicle accidents (MVA) showed a significant reduction. Among the orthopaedic diagnoses, the hip + pelvis category showed a significant decline within the study group. CONCLUSIONS: This study highlighted the impact of HM on the orthopaedic trauma epidemiology at the PRTC. Our findings provide valuable evidence to healthcare institutions to better prepare to manage the potential changes in the orthopaedic trauma epidemiology after a major atmospheric event.

RESUMO

INTRODUCTION AND IMPORTANCE: Myoepithelial tumors are under-recognized neoplasms that could be difficult to identify due to their rarity and limited comprehension. Their diverse morphology, varied cytologic features and heterogenous immunohistochemical characteristics create a significant diagnostic challenge. CASE PRESENTATION: We report the case of a 72-year-old-male patient who received conservative treatment during one year for a popliteal mass on the right knee that showed synovial hyperplasia (benign findings) at initial open tissue biopsy. New symptoms of popliteal area enlargement and discomfort required a second incisional biopsy to reach the diagnosis of a soft tissue myoepithelial tumor through tissue analysis and immunohistochemical staining. CLINICAL DISCUSSION: The myoepithelial tumors represent a medical dilemma due to their heterogenic features requiring high level of suspicion and adequate immunohistochemical markers for their diagnosis. CONCLUSION: Orthopaedic surgeons should be aware of the atypical presentation of these rare neoplasms to provide an early diagnosis and adequate management.

RESUMO

Prosthetic failure secondary to bearing fracture remains a potential complication in ceramic-on-ceramic total hip arthroplasty. We report the unusual presentation of a ceramic component fracture of a total hip arthroplasty performed 17 years ago that mimicked a periprosthetic joint infection. This case was managed based on the current guidelines and algorithms recommended for periprosthetic joint infection management. Histologic examination of periprosthetic tissue revealed an adverse inflammatory soft-tissue reaction to the ceramic fragments released from the fracture site. Our case highlights a misleading, inflammatory acute response usually associated with an infectious process corresponding to an adverse soft-tissue reaction. High clinical suspicion and a systematic approach are essential to address these deceiving clinical scenarios.

RESUMO

INTRODUCTION: The effect of surgical vs nonsurgical management on hip fracture mortality of Hispanic-American male veterans has not been rigorously studied. Hence, we examined the mortality and life expectancy effect of nonsurgical vs surgical management after hip fracture in a geriatric Hispanic-American male veterans' population. MATERIAL AND METHODS: This was a retrospective cohort study of Hispanic-American male veterans who were 65 years of age or older and suffered a femoral neck or intertrochanteric fracture from January 2008 to December 2015. Analysis between a surgical cohort (cannulated screw fixation, hemiarthroplasty, total hip arthroplasty, or cephalomedullary nail) and a non-surgical cohort was performed. In-hospital, 30-day, one-year, and two-year mortality were compared between both groups. RESULTS: Out of 268 patients with hip fracture, 159 (59.2%) were treated surgically and 109 (40.8%) non-surgically. The overall in-hospital (9.2% vs 1.9%, P = .009), 30-day (17.4% vs 5.0%, P = .002), one-year (48.6% vs 23.3%, P < .001), and two-year (63.3% vs 36.5%, P < .001) mortality rate was found to be higher for the nonoperative group. The average life expectancy of the nonoperative cohort was significantly shorter than those who were managed surgically (216 days vs 260 days, P < .001). DISCUSSION AND CONCLUSION: This study shows a higher mortality rate and lower life expectancy in geriatric male patients who were treated nonsurgically in a Veterans Health Affair hospital facility that mostly serves Hispanic-American veterans. Our results provide an expansion to the findings of other geriatric studies on hip fracture with focus in a Hispanic-American veteran male population.

RESUMO

An isolated hook of hamate fracture is an extremely rare condition in skeletally immature patients. Early diagnosis and treatment are vital for the functional outcome of athletes such as baseball players. The hook of hamate fracture may be missed at initial presentation due to nonspecific symptoms and false-negative radiographs, which may eventually lead to a nonunion. Currently, there is no clear indication of surgical intervention for nonunion of the hook of hamate in a skeletally immature patient. This report presents the case of a twelve-year-old skeletally immature male with a hook of hamate fracture who underwent surgical bone fragment excision three months after initial injury due to a nonunion of the hamate bone. At the two-year postoperative visit, excellent results were obtained, and patient was able to continue his sports activity without any functional impairment.

RESUMO

Tenosynovial chondromatosis (TC) is a rare progressive benign tumor from the synovial lining of tendon sheath. The TC mostly affects males between the ages 30 to 50 years old at the ventral side of wrist. There are two different forms of TC that have been proposed in previous studies: an idiopathic cause (primary TC) and a joint related diseases cause (secondary TC). Even though trauma has been written to be a common reason for TC, a case of a secondary TC affecting the dorsal wrist following a triquetrum fracture has never been written before. The aim of this report is to present a rare case of a solitary post-traumatic TC at the dorsal wrist following a triquetrum fracture. We describe the clinical presentation, imaging modalities, histopathological and treatment challenges to manage this difficult lesion.

RESUMO

INTRODUCTION: There is a controversy in the management of distal radius fractures (DRF) and its criteria for surgical intervention on geriatric patients. The American Academy of Orthopedic Surgeons (AAOS) developed evidence-based guidelines for treatment of DRF. The aim of this study was to evaluate the current practice of Hispanic orthopedic surgeons in the management of geriatric DRF and examine their adherence to AAOS guidelines based on years of surgical experience. MATERIAL & METHODS: A survey was emailed to all orthopedic surgeons who live in Puerto Rico and treated DRF in their daily practice. Responses concerning demographic, management and clinical scenarios were evaluated. For each clinical scenario, treatment of choice was selected with the same fracture in a geriatric and young adult patient. Comparison between years of surgical experience and adherence to the AAOS guidelines was performed. RESULTS: A total of 65 surgeons responded the survey with 65% having >15 years in practice. A high consensus with AAOS guidelines for DRF was found. Use of preoperative radiographs was reported in all respondents, with an additional 12% routine use of preoperative computed tomography scans. Seventy-seven percent of respondents did not allow any range of motion (ROM) at immediate postoperative period, while 23% allowed active or passive ROM. Use of postoperative therapy was reported in 72.3%. Correlation between years of surgical experience showed a higher use of Vitamin C postoperatively for prophylaxis of Complex Regional Pain Syndrome among surgeons <15 years (P = 0.01). A general consensus trend toward operative fixation was noted among geriatric and young adult patients with the same fracture type in all clinical scenarios. DISCUSSION AND CONCLUSIONS: This survey demonstrates a practice variation toward surgical management of geriatric DRF among Hispanic orthopedic surgeons; despite their compliance with the AAOS AUC guidelines. The geriatric DRF management does not vary significantly among years of surgical experience.

RESUMO

This is a rare case of a 42-year-old Hispanic male with macrodactyly who presented with recurrent carpal tunnel syndrome (CTS) due to Lipofibromatous Hamartoma (LFH). A slowly growing mass in his right palm with pain and numbness, along with motor and sensory deficits in the median nerve distribution, was reported since the past year prior to visit. Previous open carpal tunnel release was performed at 16 years of age due to CTS without complications. The diagnosis of LFH was made based on ultrasound, electromyography test and physical examination. An extended open carpal tunnel release with transection of transverse ligament was performed. The 24-month postoperative evaluation showed complete resolution of symptoms. This report illustrates the management of a recurrent CTS due to LFH in a Hispanic adult patient with macrodactyly that was successfully treated with a carpal tunnel decompression.

RESUMO

Purpose: Supracondylar humerus fracture (SHF) is the most common type of fracture in children. The aim of this study was to evaluate the efficacy of local hematoma block with 0.25% bupivacaine as postoperative pain control in patients with pediatric SHF who underwent closed reduction pin fixation. Methods: We performed an institutional review board-approved, prospective cohort study of 65 patients with SHF treated with closed reduction percutaneous pin fixation. For 6 months, all patients were randomly divided into 2 groups. The treatment group (35 patients) received an intraoperative local hematoma block using 0.25% bupivacaine whereas the control group (30 patients) did not receive a local hematoma block as postoperative pain management adjuvant. After surgery, all patients were prescribed opioid pain medication. To evaluate the efficacy of the hematoma block, postoperative morphine equivalent consumption and the Faces Pain Scale-Revised (FPS-R) survey were blindly recorded during postoperative day 1. Demographic data, surgical details, clinical neurovascular examination during the hospital stay, and complications were also evaluated. Results: Comparison of the control group with the treatment group showed similar morphine equivalent consumption and Face Pain Scale-Revised Survey results. No hematoma block-associated complications were reported. Conclusions: The result of this study do not favor the use of local hematoma block to improve pain control and decrease the need for opioid use on postoperative day 1 in pediatric SHF after patients undergo closed reduction percutaneous pin fixation. These results can lay the foundation for future studies while suggesting new, novel opioid-free pain control strategies in patients with SHF. Type of study/level of evidence: Therapeutic II.
