Return to Driving Following Moderate-to-Severe Traumatic Brain Injury: A TBI Model System Longitudinal Investigation.

OBJECTIVE: To examine longitudinal patterns of return to driving (RTD), driving habits, and crash rates associated with moderate-to-severe traumatic brain injury (TBI). SETTING: Eight TBI Model System sites. PARTICIPANTS: Adults (N = 334) with TBI that required inpatient acute rehabilitation with follow-up of 197 and 218 at 1 and 2 years post-injury, respectively. Data collection at 2 years occurred almost exclusively during the pandemic, which may have affected results. DESIGN: Longitudinal and observational. MAIN MEASURES: Driving survey completed during rehabilitation and at phone follow-up 1 and 2 years after injury. RESULTS: The rate of RTD was 65% at 1-year follow-up and 70% at 2-year follow-up. RTD at both follow-up time points was positively associated with family income. The frequency of driving and distance driven were diminished compared to before injury. Limitation of challenging driving situations (heavy traffic, bad weather, and at night) was reported at higher rates post-injury than before injury. Crash rates were 14.9% in the year prior to injury (excluding crashes that resulted in TBI), 9.9% in the first year post-injury, and 6% during the second year. CONCLUSION: RTD is common after TBI, although driving may be limited in terms of frequency, distance driven, and avoiding challenging situations compared to before injury. Incidence of crashes is higher than population-based statistics; however, those who sustain TBI may be at higher risk even prior to injury. Future work is needed to better identify characteristics that influence the likelihood of crashes post-TBI.

Cognitive Performance, Depression, and Anxiety 1 Year After Traumatic Brain Injury.

OBJECTIVES: To evaluate associations between depression, anxiety, and cognitive impairment among individuals with complicated mild to severe traumatic brain injury (TBI) 1 year after injury. SETTING: Multiple inpatient rehabilitation units across the United States. PARTICIPANTS: A total of 498 adults 16 years and older who completed inpatient rehabilitation for complicated mild to severe TBI. DESIGN: Secondary analysis of a prospective, multicenter, cross-sectional observational cohort study. MAIN MEASURES: Assessments of depression (Traumatic Brain Injury Quality of Life [TBI-QOL] Depression) and anxiety (TBI-QOL Anxiety) as well as a telephone-based brief screening measure of cognitive functioning (Brief Test of Adult Cognition by Telephone [BTACT]). RESULTS: We found an inverse relationship between self-reported depression symptoms and the BTACT Composite score (ß = -0.18, P < .01) and anxiety symptoms and the BTACT Composite score (ß = -0.20, P < .01). There was no evidence this relationship varied by injury severity. Exploratory analyses showed depression and anxiety were negatively correlated with both BTACT Executive Function factor score and BTACT Memory factor score. CONCLUSIONS: Both depression and anxiety have a small but significant negative association with cognitive performance in the context of complicated mild to severe TBI. These findings highlight the importance of considering depression and anxiety when interpreting TBI-related neuropsychological impairments, even among more severe TBI.

Barriers to driving and psychosocial outcomes after traumatic brain injury.

OBJECTIVE: Examine considerations and perceived barriers to return to driving, and their association with psychosocial outcomes among adults with traumatic brain injury (TBI) who were not driving. METHODS: 174 adults with moderate-to-severe TBI enrolled in the TBI Model System participated in this cross-sectional study. All participants were drivers prior to their TBI. Outcome measures included the Barriers to Driving Questionnaire, Disability Rating Scale, Patient Health Questionnaire-9, General Anxiety Disorder-7, and Satisfaction With Life Scale. Descriptive analyses examined considerations and barriers to driving, including differences associated with demographic characteristics. Moderation analyses investigated the extent to which disability moderated the relationship between barriers and psychosocial outcomes. RESULTS: Social barriers were the most strongly endorsed domain, whereas physical barriers were endorsed least. The profile of endorsements differed for men and women, and for Black and White participants, on both theoretical considerations in returning to drive and experiences of barriers in doing so. Disability level moderated the relationship between barriers to driving and depression and life satisfaction, but not anxiety. CONCLUSION: The experience of barriers to driving is differentially associated with psychosocial outcomes among nondriving adults with TBI. Adults with low disability appear to be at risk for distress, even compared to other nondrivers.

Crash Risk Following Return to Driving After Moderate-to-Severe TBI: A TBI Model Systems Study.

OBJECTIVE: To examine motor vehicle crash frequency and risk factors following moderate-to-severe traumatic brain injury (TBI). SETTING: Eight TBI Model Systems sites. Participants: Adults ( N = 438) with TBI who required inpatient acute rehabilitation. DESIGN: Cross-sectional, observational design. MAIN MEASURES: Driving survey completed at phone follow-up 1 to 30 years after injury. RESULTS: TBI participants reported 1.5 to 2.5 times the frequency of crashes noted in the general population depending on the time frame queried, even when accounting for unreported crashes. Most reported having no crashes; for those who experienced a crash, half of them reported a single incident. Based on logistic regression, age at survey, years since injury, and perception of driving skills were significantly associated with crashes. CONCLUSION: Compared with national statistics, crash risk is higher following TBI based on self-report. Older age and less time since resuming driving were associated with lower crash risk. When driving was resumed was not associated with crash risk. These results do not justify restricting people from driving after TBI, given that the most who resumed driving did not report experiencing any crashes. However, there is a need to identify and address factors that increase crash risk after TBI.

One and a Half-Stage Revision With Prosthetic Articulating Spacer for Definitive Management of Knee Periprosthetic Joint Infection.

This paper is a comprehensive review that describes indications, contraindications, clinical outcomes, and pearls and pitfalls of 1.5-stage revision total knee arthroplasty (TKA) utilizing a primary TKA femoral component, all-polyethylene tibial component, and hand-crafted antibiotic cement for the management of chronic periprosthetic joint infection. The 1.5-stage exchange TKA details placement of an articulating spacer for an indefinite period, prolonging revision until reinfection, deterioration of functional status, or construct failure. A 1.5-stage revision TKA technique is a viable option for treatment of chronic periprosthetic knee infections. The inherent advantages of decreased health-care costs, decreased morbidity and mortality, and improved emotional ease from having a single procedure is attractive, especially if reinfection rates are determined to be equivocal to 2-stage revision.

Severity and correlates of brain fog in people with traumatic brain injury.

Brain fog is one symptom that has been underexplored in traumatic brain injury (TBI). We explored the cognitive and affective correlates of brain fog in people with symptomatic mild TBI (n = 15), moderate-to-severe TBI (n = 15), and a healthy control group (n = 16). Measures across the studies assessed "brain fog" (Mental Clutter Scale), objective cognition (Useful Field of View® and Cogstate Brief Battery®), post-concussive symptoms (Post-Concussion Symptom Scale), and depressive symptoms (Profile of Moods Scale). Brain fog was higher in symptomatic mild TBI and moderate-to-severe TBI compared with healthy controls. Greater brain fog corresponded to greater depressive symptoms in symptomatic mild TBI. Greater brain fog corresponded to poorer episodic memory and working memory in moderate-to-severe TBI. Brain fog appears to reflect challenges in recovery, including depressive symptoms and worse cognitive function. Screening for brain fog might be worthwhile in people with brain injuries.

Phenotypic Frailty Score Predicts Perioperative Outcomes for Geriatric Total Joint Arthroplasty.

Various assessment tools are often used to predict perioperative morbidity among patients older than 75 years who undergo total joint arthroplasty. Yet, few studies describe the use of phenotypic frailty as a predictor for outcomes. The goal of this study was to assess phenotypic frailty with the Sinai Abbreviated Geriatric Evaluation (SAGE) and compare its utility with established assessment tools used in practice. We specifically asked: (1) Can SAGE predict 30-day outcomes, including postoperative delirium? (2) Can SAGE determine the risk of prolonged hospital length of stay? (3) Is SAGE predictive for 30-day readmissions? (4) Can SAGE determine the risk of discharge to a specialized facility? Patients undergoing total hip arthroplasty and total knee arthroplasty were evaluated with the American Association of Anesthesiologists Physical Status (ASA), Charlson Comorbidity Index (CCI), 5-point Modified Frailty Score (5-FS), and SAGE. Assessment scores were determined for each patient, and every incremental change in score was used to predict the likelihood of perioperative complications. A receiver operating characteristic analysis was also performed to calculate testing sensitivity for each assessment tool. The SAGE scores were more likely to predict 30-day complications (odds ratio [95 CI], 2.21 [1.32-3.70]), postoperative delirium (6.40 [1.78-23.03]), and length of stay greater than 2 days (3.90 [1.00-15.7]) compared with ASA, CCI, and 5-FS values. The SAGE scores were not predictive of readmission (1.77 [0.66-4.72]) or discharge to a specialized facility (1.48 [0.80-2.75]). The SAGE score was a more sensitive predictor (area under the curve, 0.700) for perioperative morbidity compared with ASA (0.638), CCI (0.662), and 5-FS (0.644) values. Therefore, SAGE scores can reliably assess risk of perioperative morbidity and may have better clinical utility than ASA, CCI, and 5-FS values for patients undergoing total joint arthroplasty.

Revision Distal Femoral Replacement for Patello-Femoral Maltracking: A Surgical Technique.

The use of the distal femoral replacement (DFR) has grown in recent years. Historically, this procedure was reserved for malignancy and complex revision cases with relative success. In recent years, complex reconstruction cases have had relative success. DFR has been associated with a range of complications including anterior knee pain, patellar instability, limitations in knee motion, and rotational instability that are sequelae of altered patello-femoral mechanics. Thus, subsequent dysfunction may require revision. To our knowledge, no surgical technique to correct DFR patello-femoral maltracking has been demonstrated in current literature. We present a surgical technique for DFR patello-femoral maltracking corrected surgically with femoral component revision and femoral stem retention.

Health and cognition among adults with and without Traumatic Brain Injury: A matched case-control study.

OBJECTIVES: To evaluate associations between traumatic brain injury (TBI) and presence of health conditions, and to compare associations of health and cognition between TBI cases and controls. METHODS: This matched case-control study used data from the TBI Model Systems National Database (TBI cases) and Midlife in the United States II and Refresher studies (controls).  248 TBI cases were age-, sex-, race-, and education-matched without replacement to three controls. Cases and controls were compared on prevalence of 18 self-reported conditions, self-rated health, composite scores from the Brief Test of Adult Cognition by Telephone. RESULTS: The following conditions were significantly more prevalent among TBI cases versus controls: anxiety/depression (OR = 3.12, 95% CI: 2.20, 4.43, p < .001), chronic sleeping problems (OR = 2.76, 95% CI: 1.86, 4.10, p < .001), headache/migraine (OR = 2.61, 95% CI: 1.50, 4.54, p = .0007), and stroke (OR = 6.42, 95% CI: 2.93, 14.10, p < .001). The relationship between self-rated health and cognition significantly varied by TBI (pinteraction = 0.002). CONCLUSION: Individuals with TBI have greater odds of selected neurobehavioral conditions compared to their demographically similar uninjured peers. Among persons with TBI there was a stronger association between poorer self-rated health and cognition than controls. TBI is increasingly conceptualized as a chronic disease; current findings suggest post-TBI health management requires cognitive supports.

Providing Inpatient Mobilization with a Mobility Technician Constrains Cost in Primary Total Knee Arthroplasty.

Since the 2016 implementation of the comprehensive care for joint replacement (CJR) bundled payment model, our institutions have sought to decrease inpatient physical therapy (PT) costs by piloting a mobility technician program (MTP), where mobility technicians (MTs) ambulate postoperative total knee arthroplasty (TKA) patients under the supervision of nursing staff members. MTs are certified medical assistants given specialized gate and ambulation training by the PT department. The aim of this study was to examine the economic and clinical impact of MTs on the primary TKA postoperative pathway. We performed a retrospective review of TKA patients who underwent surgery at our institution between April 2018 and March 2019 and who were postoperatively ambulated by MTs. The control group included patients who had surgery during the same months of the prior year, preceding introduction of MTs to the floor. Inclusion criteria included: unilateral primary TKA for arthritic conditions and conversion to unilateral primary TKA from a previous knee surgery. Minitab Software (State College, PA) was used to perform the statistical analysis. There were 658 patients enrolled in the study group and 1,400 in the control group. The two groups shared similar demographics and an average age of 68 (p = 0.177). The median length of stay (LOS) was 2 days in both groups (p = 0.133) with 90.5% of patients in the study group discharged to home versus 81.5% of patients in the control group (p < 0.001). The ability of MTs to increase patient discharge to home without negatively impacting LOS suggest MTs are valuable both clinically to patients, and economically to the institution. Cost analysis highlighted the substantial cost savings that MTs may create in a bundled payment system. With the well-documented benefits of early ambulation following TKA, we demonstrate how MTs can be an asset to optimizing the care pathway of TKA patients.

Driving patterns, confidence, and perception of abilities following moderate to severe traumatic brain injury: a TBI model system study.

OBJECTIVE: Describe driving patterns following moderate-to-severe traumatic brain injury (TBI). Participants: Adults (N = 438) with TBI that required inpatient acute rehabilitation who had resumed driving. DESIGN: Cross-sectional, observational design. SETTING: Eight TBI Model System sites. MAIN MEASURES: A driving survey was completed at phone follow-up. RESULTS: Most respondents reported driving daily, although 41% reported driving less than before their injury. Driving patterns were primarily associated with employment, family income, sex, residence, and time since injury, but not injury severity. Confidence in driving was high for most participants and was associated with a perception that the TBI had not diminished driving ability. Lower confidence and perceived loss of ability were associated with altered driving patterns. CONCLUSION: Most people with moderate-to-severe TBI resume driving but perhaps not at pre-injury or normal levels compared to healthy drivers. Some driving situations are restricted. The relationship between low confidence/perceived loss of ability and driving patterns/restrictions suggests people with TBI are exhibiting some degree of caution consistent with those perceptions. Careful assessment of driving skills and monitoring during early stages of RTD is warranted, particularly for younger, male, and/or single drivers who express higher levels of confidence.

Is There a Need for Recovery Room Radiographs Following Uncomplicated Primary Total Knee Arthroplasty?

Introduction Total knee arthroplasty (TKA) is one of the most common orthopedic procedures performed in the United States. Obtaining radiographs in the post-anesthesia care unit (PACU) has been the standard of care at most hospitals. The purpose of this study was to examine the utility and cost-effectiveness of immediate, postoperative radiographs in regards to operative decision-making to prevent complications within 90 days after primary TKA. Methods A retrospective review of 4,830 consecutive patients who underwent cemented or uncemented TKA between January 2016 and June 2019 at a large, regional medical center was performed. International Classification of Diseases, Tenth Revision (ICD-10) codes were used to track any readmissions within 90 days of TKA. If readmission was for a mechanical complication, including fracture, dislocation, or component loosening, PACU radiographs were reviewed for any abnormalities that may have prevented readmission. Results There were 195 readmissions (195 patients), of which 17 were due to mechanical complications. There was no evidence of fracture or abnormality appreciated on any of the reviewed PACU radiographs by either the reading radiologist or the senior authors. Assuming all fractures were noted on immediate, postoperative radiographs, the cost associated with identifying a single fracture in 2,415 patients was $1,072,260. Conclusion Routine radiographs in the recovery room after an uncomplicated primary TKA are not a reliable mechanism for preventing mechanical complications and do not alter patient care.

Patterns of Functional Change Five to Ten Years after Moderate-Severe Traumatic Brain Injury.

This study aims to characterize the patterns of functional change experienced between 5 and 10 years after moderate-severe traumatic brain injury (TBI). The study included TBI Model Systems national database participants (N = 372) at six sites who experienced TBI, received inpatient rehabilitation, and were followed at 5 and 10 years post-TBI. Outcome measures included self- or proxy-reported Functional Independence Measure (FIMTM) structured interview at 5 and 10 years post-TBI and domain change indices (DCIs) at 10 years to assess subjective change over the previous 5 years. When all seven FIM and subjective DCI subscales were considered together, 69% reported improvement in at least one subscale and 41% reported decline in at least one subscale; 51% reported more domains improved than declined, and 20% reported more domains declined than improved. Age at injury, post-traumatic amnesia duration, FIM, and depression and anxiety at year 5 were associated with FIM change and DCI measures. Although most persons with moderate-severe TBI do not experience widespread change from year 5 to 10 on individual FIM subscales or perceived domain-specific subscales, the vast majority do report change in one or more domains, with more improvement than decline and more change in subjective DCI than in FIM. Clinicians and researchers should be alert to the possibility of both positive and deleterious changes many years after TBI.

Predictors of Driving Status in Service Members and Veterans at 1 Year Posttraumatic Brain Injury: A VA TBI Model Systems Study.

OBJECTIVE: To identify predictors of driving status in service members and veterans 1 year following a traumatic brain injury (TBI). SETTING: The 5 Department of Veterans Affairs (VA) Polytrauma Rehabilitation Centers (PRCs). PARTICIPANTS: A total of 471 service members and veterans (128 with mild/complicated mild TBI and 343 with moderate/severe TBI) who received TBI-focused inpatient rehabilitation at one of the VA PRCs and who participated in a 1-year postinjury follow-up assessment. DESIGN: Secondary analysis from the Department of Veterans Affairs Polytrauma Rehabilitation Centers Traumatic Brain Injury Model Systems (VA PRC TBIMS) national database. MAIN MEASURES: Primary outcome was a single item that assessed driving status at 1 year postinjury. Predictor variables included demographics; sensory impairment, substance use, and employment status at time of injury; PTSD symptoms reported at study enrollment; and functional impairment rated at rehabilitation discharge. RESULTS: In unadjusted bivariate analyses, among those with a mild/complicated mild TBI, older age and greater functional impairment were associated with lower likelihood of driving. Among those with a moderate/severe TBI, discharge to a nonprivate residence, greater functional impairment, and higher PTSD symptoms were linked to lower likelihood of driving. Adjusted multivariate analyses indicated that functional impairment was uniquely associated with driving status in both TBI severity groups. After controlling for other predictors, self-reported PTSD symptoms, particularly dysphoria symptoms, were associated with lower likelihood of driving in both severity groups. CONCLUSION: Given the significance of clinician-rated functional impairment and self-reported PTSD symptoms to the prediction of driving status 1 year post-TBI among service members and veterans, rehabilitation efforts to improve functioning and reduce negative affect may have a positive impact on driving and community integration.

Return to Driving After Moderate-to-Severe Traumatic Brain Injury: A Traumatic Brain Injury Model System Study.

OBJECTIVE: Describe who is able to return to driving (RTD) after moderate-to-severe traumatic brain injury (TBI), when this occurs, who maintains that activity, and the association with outcome. DESIGN: Cross-sectional descriptive study. SETTING: Eight follow-up sites of the TBI Model Systems (TBIMS) program. PARTICIPANTS: 618 participants enrolled in the TBIMS and 88 caregivers (N=706). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A survey was completed from 1-30 years postinjury focusing on RTD. Descriptors included demographic information, injury severity, and current employment status. Outcome was assessed at the time of the interview, including depression, quality of life, functional status, and community participation. RESULTS: Of 706 respondents, 78% (N = 552) RTD, but 14% (N = 77) of these did not maintain that activity. Of those who RTD, 43% (N = 192) did so within 6 months of the injury and 92% did so within 24 months postinjury. The percentage of people driving after TBI did not differ significantly based on age at time of injury or follow-up. There were significant differences between drivers and nondrivers with respect to severity of injury, seizures, race, education, employment, rural vs urban setting, marital status, and family income. We performed a multivariate logistic regression to examine the association between driving status and demographic variables, adjusting for other variables in the model. The strongest associations were with current employment, family income, race, seizures, and severity of injury. Driving was associated with greater community participation, better functional outcomes, fewer symptoms of depression, and greater life satisfaction. CONCLUSIONS: Over a span of 30 years, three-quarters of people experiencing moderate-to-severe TBI return to driving a personal vehicle, although not everyone maintains this activity. Employment, race, family income, and seizures are strongly associated with RTD.

Research Letter: Performance of the Brief Test of Adult Cognition by Telephone in a National Sample.

OBJECTIVE: To create a larger, more representative community comparison sample of the Brief Test of Adult Cognition by Telephone (BTACT) data to facilitate assessment of cognitive function in research studies. SETTING: National US community-based survey. PARTICIPANTS: In total, 6747 healthy adults aged 23 to 84 years (53% female; mean age = 55 years, SD = 13). DESIGN: Secondary data analysis of BTACT data collected from the National Survey of Midlife Development in the United States (MIDUS) II and MIDUS Refresher cohorts. MAIN MEASURES: The BTACT, a brief (15-20 minute) measure of global cognitive function validated for telephone administration. RESULTS: This article provides BTACT community comparison sample data based on age, sex, and education from a national sample. Similar to other cognitive measures, BTACT scores decreased with age and increased with education. CONCLUSIONS: The BTACT community comparison sample will facilitate investigation of cognitive functioning in large-scale traumatic brain injury research studies and will support secondary analysis of existing BTACT data gathered through the MIDUS study.

Convergent Validity of In-Person Assessment of Inpatients With Traumatic Brain Injury Using the Brief Test of Adult Cognition by Telephone (BTACT).

OBJECTIVE: To examine convergent validity of the Brief Test of Adult Cognition by Telephone (BTACT) by determining correlation with established neuropsychological tests, administered an average of 4.4 days apart, in an inpatient traumatic brain injury (TBI) population. SETTING: Acute inpatient rehabilitation hospital. PARTICIPANTS: Fifty-five patients receiving inpatient rehabilitation for new-onset TBI (69.1% male; mean age = 37 years, SD = 14 years). DESIGN: Cross-sectional, secondary data analysis. MAIN MEASURES: BTACT; California Verbal Learning Test-second edition (CVLT-2); Wechsler Adult Intelligence Scale-IV (WAIS-IV) Digit Span; Trail Making Test; semantic fluency; phonemic fluency; Symbol Digit Modalities Test; Wisconsin Card Sorting Test. RESULTS: The BTACT was significantly associated with established neuropsychological tests across composite scores of overall cognition (r = 0.64, P < .001), episodic verbal memory (r = 0.66, P < .001), and executive function (r = 0.56, P < .001). For BTACT subtests, Word List Immediate Recall and Word List Delayed Recall were correlated with CVLT-2 learning trials total score (r = 0.57, P < .01) and long delay free recall (r = 0.60, P < .001), respectively. BTACT Digits Backward correlated with WAIS-IV Digit Span (r = 0.51, P < .01). BTACT Animal Fluency was associated with semantic fluency (r = 0.65, P < .01), phonemic fluency (r = 0.60, P < .01), and Trail Making Test Part B (r = 0.39, P < .01). CONCLUSION: BTACT composite scores of overall cognition, verbal memory, and executive function demonstrate initial convergent validity in a TBI inpatient population. Future research should examine validity in a larger sample of individuals with TBI.

Factors Complicating Discharge to Home following Total Knee Arthroplasty-A Single Institution Initiative.

Recently, with the Medicare bundled payments initiative for total knee arthroplasty (TKA), there has been a move by many institutions to further streamline costs associated with the entire operative and perioperative process. One of these cost-saving strategies has been to favor discharging patients to home with outpatient services as opposed to discharging to the relatively more expensive rehabilitation facilities. Our aim was to determine the success of a teaching institute's initiative in discharging patients to home instead of a rehabilitation facility. Specifically, we evaluated if there were differences in discharge disposition based off of (1) surgeon/patient preference, (2) length of stay, (3) demographics, and (4) postoperative complications. A retrospective review of all patients who had a TKA from 2015 to 2017 at a single teaching institution was performed and assessed discharge to home or to a rehabilitation facility. If they were not discharged to home, we evaluated why that did not happen, stratified the reason they were discharged to a rehabilitation facility into four groups based on (1) physician and occupational health team assessment, (2) patient preference, (3) physician preference, and (4) family or caretaker preference. A total of 229 patients were enrolled in this initiative, with 107 patients (47%) discharged to home with outpatient physical therapy services and 122 (53%) discharged to a rehabilitation facility. Of these, 35 patients (29%) went to these facilities because of physician and occupational health team assessment. However, 31 (25%) patients were due to patient preference, 32 (26%) were because of surgeon's preference, and 24 (20%) were not discharged to home because of family or caretaker preference. There were no differences in length of stay, gender, or complication rates between cohorts. Many patients can be safely discharged to home following TKA at a community teaching institution; however, there continues to be a strong prejudice by patients, physicians, and caretakers to be discharged to a rehabilitation facility despite the home discharge initiative.

Primary Extramedullary, Extradural Cervical Spine Seminoma.

While extragonadal seminomas resulting in spinal cord compression are rarely reported in the literature, most have been treated with surgical decompression followed by radiation therapy. In this report, we present the unique and interesting case of a 38-year-old man who initially presented as an outpatient with a chief complaint of axial neck pain and lateral thoracic wall pain. After an extensive malignancy workup, he was diagnosed with a primary cervical spine seminoma and was treated with a C6-T1 laminectomy with posterior spinal instrumentation from C5 to T2. He has since undergone chemotherapy with cisplatin, vinblastine, and bleomycin, and at 24-month follow-up, he remains asymptomatic with no signs of recurrent disease.

Nail Salon a Potential Source of a Rare Mycobacterium Fortuitum Infection In Proximal Tibia Megaprosthesis? A Case Report.

Mycobacterium Fortuitum (M. Fortuitum) is a type of opportunistic pathogen commonly found in water/soil and belongs to the nontuberculosis mycobacteria (NTM) family. Prosthetic joint infection due to M. Fortuitum is extremely rare. We present a case of a 21-year-old female with an infection following a radical resection of the proximal tibia due to a parosteal osteosarcoma.
