Study Design: Retrospective cohort study Objectives: The purpose of this study is to compare patient-reported outcome measures (PROMs) for patients undergoing one-to three-level lumbar fusion using robotically assisted vs freehand pedicle screw placement. Methods: Patients who underwent either robotically assisted or freehand pedicle screw placement for one-to three-level lumbar fusion surgery from January 1, 2014 to August 31, 2020 at a single academic institution were identified. Propensity score matching was performed based on demographic variables. Clinical and surgical outcomes were compared between groups. Recovery Ratios (RR) and the proportion of patients achieving the minimally clinically important difference (%MCID) were calculated for Oswestry Disability Index, PCS-12, MCS-12, VAS Back, and VAS Leg at 1 year. Surgical outcomes included complication and revision rates. Results: A total of 262 patients were included in the study (85 robotic and 177 freehand). No significant differences were found in ΔPROM scores, RR, or MCID between patients who underwent robotically assisted vs freehand screw placement. The rates of revision (1.70% freehand vs 1.18% robotic, P = 1.000) and complications (.57% freehand vs 1.18% robotic, P =.546) were not found to be statically different between the 2 groups. Controlling for demographic factors, procedure type (robotic vs freehand) did not emerge as a significant predictor of ΔPROM scores on multivariate linear regression analysis. Conclusions: Robotically assisted pedicle screw placement did not result in significantly improved clinical or surgical outcomes compared to conventional freehand screw placement for patients undergoing one-to three-level lumbar fusion.

Study Design: Systematic Review. Objectives: To systematically review the current literature and perform a meta-analysis on patients with cervical or lumbar spine Modic changes to determine if their baseline axial back pain and disability are comparable to patients without Modic changes. Methods: A systematic review of the PubMed database was conducted in accordance with PRISMA guidelines. A meta-analysis was performed to compare the mean differences in back pain, leg pain, and disability based on the presence of cervical or lumbar spine Modic changes. A subgroup analysis of the different types of Modic changes was conducted to determine if Modic type affected back pain or disability. Results: – After review of 259 articles, 17 studies were included for meta-analysis and ten studies were included for qualitative synthesis. In the lumbar spine, 10 high-quality studies analyzed Visual Analog Scale (VAS) back pain, 10 evaluated VAS leg pain, and 8 analyzed Oswestry Disability Index. VAS back pain (mean difference (MD), −.38; 95% CI, -.61 –.16) and Oswestry disability index (MD −2.52; 95% CI, −3.93 – −1.12) were significantly lower in patients without Modic changes. Modic change subtype was not associated with differences in patient-reported outcomes. Patients with cervical spine Modic changes did not experience more severe pain than those without MC. Conclusions: Modic changes in the lumbar spine are not associated with clinically significant axial low back pain severity or patient disability. Similar to the lumbar spine, Modic changes in the cervical spine are not associated with symptom severity, but they are associated with pain duration. [ABSTRACT FROM AUTHOR]

Background: Patient adherence is important for maximizing patient outcomes. The purpose of this randomized controlled trial was to determine patient adherence and confidence in home therapy exercises of the hand and wrist at multiple time points when distributed by either paper handout or video. Methods: Patients were prospectively enrolled and randomized in orthopedic clinics to either the handout or video exercise group. Exclusion criteria included patients less than 18 years old. Questionnaires were electronically distributed each week for 4 weeks following enrollment. Questionnaires assessed the frequency of exercise performance, percentage of exercises utilized, and confidence in performing the exercises correctly. The handout and video groups were compared via 2-sample t tests for continuous data and χ2 tests for categorical data. Results: Of the 89 patients enrolled, 71 patients responded to the initial follow-up survey (80% of randomized patients), and 54 of these patients (76%) completed all surveys at each time point. The handout group (37 patients) and the video group (34 patients) had no differences in response rate or demographics. There were no differences in frequency, exercise utilization rate, or confidence in performing exercises between groups at week 1. However, the video group reported higher exercise utilization and confidence than the handout group at subsequent time points. Conclusions: Video-format distribution of home therapy exercises is superior to that of paper handout distribution for the distal upper extremity rehabilitation. Patients in the video group utilized more exercises and had higher confidence in completing them correctly following initiation of the exercise program. [ABSTRACT FROM AUTHOR]

Background: Patient comprehension is an essential part of optimizing medical outcomes. It is unknown which format is most effective in delivering this information. In addition to a face-to-face conversation, a paper handout is often given as an educational supplement at the conclusion of a visit. Secondary to advances in technology and the ubiquity of the Internet, medical videos have gained popularity. The purpose of this randomized controlled trial was to determine whether the educational material format (paper handout vs video) resulted in a difference in either comprehension of the condition or satisfaction with the delivery of the information. Methods: Patients aged ≥18 years with a diagnosis of trigger finger were prospectively enrolled and randomized to receive either a paper handout or video link with information regarding the pathophysiology, diagnosis, and treatment of trigger finger. Survey assessments were then distributed, consisting of 7 questions related to trigger finger and 1 question related to patient satisfaction. Continuous data were compared using 2-sample t tests, and categorical data were compared with χ2 tests. Alpha was 0.05. Results: Seventy-one patients were enrolled, and 60 completed their survey (response rate: 85%). The video group had significantly higher comprehension scores (82% vs 71%, P =.04) and significantly higher satisfaction scores (9.4 vs 8.6, P =.02). Conclusions: Those who received their educational material in a video format had greater comprehension of their condition and higher satisfaction compared with those receiving a paper handout. Medical providers should consider using video formats to provide supplemental educational materials to their patients. [ABSTRACT FROM AUTHOR]

Study Design.: Retrospective cohort study. Objective.: To determine if myelopathy severity predicted the magnitude of improvement in health-related quality of life metrics following anterior cervical discectomy and fusion (ACDF). Summary of Background Data.: Surgery for myelopathy is primarily performed to halt disease progression. However, it is still controversial if these patients can expect significant health-related quality-of life improvements following ACDF. We explore the relationship between modified Japanese Orthopaedic Association (mJOA) improvements and its effect on other health-related quality-of life metrics. Materials and Methods.: Patients undergoing ACDF for myelopathy were grouped based on preoperative mJOA scores into mild (15–17), moderate (12–14), and severe (<12) groups. Patients were subsequently categorized based on if they attained the minimum clinically detectable improvement (MCID) threshold for mJOA. Multivariate linear regression was performed to determine the magnitude of improvement in ∆patient-reported outcome measures. Results.: A total of 374 patients were identified for inclusion. Of those, 169 (45.2%) had mild myelopathy, 125 (33.4%) had moderate, and 80 (21.4%) had severe myelopathy. Only the moderate and severe groups had significant improvements in mJOA following surgery (mild: P =0.073, moderate: P <0.001, severe: P <0.001). There were no significant differences in the magnitude of improvement for any patient-reported outcome measure based on myelopathy severity, except for mJOA (mild: 0.27, moderate: 1.88, severe: 3.91; P <0.001). Patients meeting the MCID for mJOA had better ∆Short-Form 12 Mental Component Score (3.29 vs. −0.21, P =0.007), ∆Short-Form 12 Physical Component Score (6.82 vs. 1.96, P <0.001), ∆Visual Analog Scale Neck (−3.11 vs. −2.17, P =0.001), ∆Visual Analog Scale Arm (−2.92 vs. −1.48, P <0.001), ∆Neck Disability Index (−18.35 vs. −7.86, P <0.001), and ∆mJOA (3.38 vs. −0.56, P <0.001) compared with patients who did not. Conclusions.: Worse baseline myelopathy severity predicts worse postoperative outcomes. However, baseline myelopathy severity is not predictive of the magnitude of postoperative improvement with the exception of mJOA. Patients who attain MCID improvement in mJOA had greater postoperative improvement for other health-related quality of life metrics. [ABSTRACT FROM AUTHOR]

Background: Stratification of the fracture risk is an important treatment component for patients with multiple myeloma, which is associated with up to an 80% risk of pathologic fracture. The Mirels score, which is commonly used to estimate the fracture risk for patients with osseous lesions, was evaluated in a cohort in which fewer than 15% of lesions were caused by multiple myeloma. The behavior of multiple myeloma lesions often differs from that of lesions caused by metastatic disease, and accurate risk stratification is critical for effective care. To our knowledge, the Mirels score has not been validated specifically for multiple myeloma.Questions/purposes: Our purpose was: (1) To develop a novel scoring system for the prediction of pathologic fracture in patients with long-bone lesions from multiple myeloma; and (2) to compare the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and receiver operating characteristic (ROC) area under curve (AUC) between the novel scoring system and the Mirels system.Methods: Between 2003 and 2017, 763 patients at one center with the diagnosis of multiple myeloma were reviewed, of whom 174 presented with long-bone disease involvement. Of those, 5% (nine of 174) were missing data or radiographs at a minimum of 1 year and had not reached an endpoint (fracture or surgery) before that time and were therefore excluded. Many patients have more than one lesion; consequently, we used the largest lesion in each patient, resulting in 163 lesions in as many patients. Ten percent (16 of 163) of these patients eventually developed a fracture and 4% (six of 163) underwent prophylactic stabilization (excluded from analysis because of outcome uncertainty). During the study period, prophylactic stabilization was performed at the discretion of the orthopaedic oncologist. Fifty-one percent (83 of 163) of patients were female, and the mean (± SD) age was 60 ± 10 years at radiographic lesion identification. All lesions were characterized before determining whether the patient underwent pathologic fracture. We identified variables associated with pathologic fracture on univariate analysis. Variables independently significant on logistic regression analysis were used to generate scoring algorithms at varying weights and scoring cutoffs for comparison via ROC curves. We then selected a novel score based on ROC performance, and compared the sensitivity, specificity, PPV, and NPV of that scoring system to that of Mirels score. ROC AUCs were compared after bootstrapping 100,000 iterations. Alpha was set at 0.05.Results: After controlling for potential confounders, such as age, sex, and duration of myeloma diagnosis, we found the following factors were independently associated with the occurrence of pathologic fracture: larger lesion size (area, cm2) (log odds 0.17; p = 0.03), longer lesion latency (years from diagnosis to lesion identification) (log odds 0.25; p = 0.03), presence of pain (relative risk [RR] 2.9; p = 0.04), and metaphyseal location (RR 3.2, compared with epiphyseal or diaphyseal; p = 0.003). These variables were used to formulate a novel scoring system. Compared with the Mirels system, the novel system was more sensitive (69% [95% CI 61 to 76] versus 38% [95% CI 30 to 46]; p < 0.05) but not different in terms of specificity (87% [95% CI 80 to 91] versus 87% [95% CI 81 to 92]; p > 0.05), PPV (37% [95% CI 29 to 45] versus 25% [95% CI 19 to 33]; p > 0.05), NPV (96% [95% CI 91 to 99] versus 92% [95% CI 87 to 96]; p > 0.05), or AUC (0.85 [95% CI 0.74 to 0.92] versus 0.67 [95% CI 0.51 to 0.81]; p > 0.05).Conclusion: The novel scoring system was found to be more sensitive than the Mirels system for predicting pathologic fracture in our retrospective cohort of patients with multiple myeloma-related bone disease. Specificity, PPV, NPV, and ROC AUC were not different with the numbers available. Thus, the novel scoring system may serve as a more effective screening tool to determine which patients with multiple myeloma would benefit from further radiologic or orthopaedic evaluation based on a skeletal survey.Level Of Evidence: Level III, diagnostic study.

Introduction: Postoperative dislocation of unclear etiology remains a concern after total hip arthroplasty (THA). Interest is growing in the importance of spinopelvic alignment on stability in THA. The purpose of this study was to analyze publication trends, areas of interest, and future research direction of spinopelvic alignment in THA., Methods: Articles on the topic of spinopelvic alignment in THA published between 1990 and 2022 were obtained through Web of Science Core Collection of Clarivate Analytics (WSCCA). Results were screened by title, abstract, and full text. The inclusion criterion was English-language peer-reviewed journal publications on the clinical topic of spinopelvic alignment in THA. Bibliometric software was used to characterize publication trends., Results: We screened 1,211 articles, yielding 132 meeting the inclusion criterion. From 1990 to 2022, published articles have steadily increased, peaking in 2021. Countries that have been the most productive in contributions to research are those in which THA is the most prevalent. Our analysis of keyword frequency showed increasing interest in "pelvic tilt," "anteversion," and "acetabular component" position., Conclusion: Our study identified that increasing attention is being given to spinopelvic mobility and PT in the setting of THA. The United States and France produced the most studies related to spinopelvic alignment., (Copyright © 2023 The Authors.

Background: The purpose of this study was to compare percutaneous pinning versus splinting of soft tissue mallet finger injury to determine if there are differences in residual extensor lag and complication rates. Methods: Patients ≥18 years of age undergoing mallet finger injury treatment from 2011 to 2020 were retrospectively reviewed. Exclusion criteria included bony or open mallet finger injury and incomplete documentation of residual extensor lag at final follow-up. Complications, including infection, hardware fixation failure and wound complications, were collected from follow-up clinic notes. Those treated with percutaneous pinning were compared to those treated non-surgically with splinting. Results: Of the 150 soft tissue mallet finger injuries that met the inclusion criteria, 126 were treated with splinting, and 24 were treated with percutaneous pinning. There were no differences in residual extensor lag between groups (Splinting: 5.4°, Pinning: 5.8°, p = 0.874). However, the pinning group had a higher overall complication rate than the splinting group (20.8% vs. 1.6%, p = 0.001). Conclusions: Surgery may be an effective treatment method for soft tissue mallet finger, but due to the higher rate of complication and the increased expense of a surgical procedure, splinting should be the preferred treatment method for most of these injuries. Level of Evidence: Level III (Therapeutic).

Introduction: Orthopaedic surgeons face decreased reimbursement, lower income, and increased rates of burnout. As subspecializing through fellowship training in orthopaedics becomes more and more prevalent, the value of membership to a general orthopaedic society (American Academy of Orthopaedic Surgeons [AAOS]) warrants investigation., Methods: One hundred thirty orthopaedic surgeons were surveyed by e-mail through a 14-item anonymous survey administered through SurveyMonkey. The survey inquired about surgeon experience, practice type, fellowship training, and details regarding AAOS and subspecialty society membership., Results: The response rate was 67%, with 94% of respondents indicating that they were members of AAOS and a subspecialty society. The most common reasons for AAOS membership were tradition (65, 74.7%), continuing medical education (46, 52.9%), maintenance of board certification (44, 50.6%), and political advocacy (40, 46.0%). The most common reasons for subspecialty society membership were continuing medical education (73, 83.9%), tradition (49, 59.8%), and political advocacy (33, 40.2%)., Discussion: Most surgeons in our study cohort were members of both AAOS and a subspecialty society, but the reasons for membership in each differed. Almost 80% of respondents think their subspecialty society provides all their professional needs. The orthopaedic societies need to continue to evolve to provide value to their members to succeed in the future., (Copyright © 2022 The Authors.

The purpose of this study was to assess the influence of the COVID-19 pandemic on the 2021 orthopaedic surgery residency match outcomes. Because in-person away rotations and interviews were canceled during the 2020 to 2021 application cycle, we hypothesized that applicants would match at their home program at a higher rate in 2021 than in previous years., Methods: We queried allopathic orthopaedic surgery residency websites and social media accounts for names of residents and medical school information for cohorts matching from 2017 through 2021. To assess availability of and participation in virtual away rotations, we administered a survey to Accreditation Council for Graduate Medical Education-accredited allopathic orthopaedic surgery residency programs. The primary outcome was the annual proportion of applicants matching at the program affiliated with their medical school ("home program"). Subgroup analyses were stratified by Doximity reputation ranking and availability of a virtual away rotation., Results: We identified 2,632 residents who matched between 2017 and 2020 and 698 residents who matched in 2021. Overall home program match rate and likelihood of home matching were higher in 2021 compared with 2017 to 2020 (28% vs. 20%; odds ratio [OR] = 1.51, 95% confidence interval [CI] 1.24-1.82, p < 0.001). The increase in the home match rate at programs ranked in the top 30 (27% vs. 20%, p = 0.034) was similar to the increase at programs ranked outside the top 30 (28% vs. 20%, p < 0.001). Of the 66 (48%) programs that responded to the survey, 16 (24%) offered a virtual away rotation. Programs with a higher Doximity ranking were more likely than lower-ranked programs to offer a virtual away rotation (OR = 6.75, 95% CI 1.95-23.4, p = 0.003). Home match rates did not differ significantly between programs that offered a virtual away rotation and those that did not (26% vs. 32%, p = 0.271)., Conclusions: A higher proportion of orthopaedic surgery residency applicants matched at their home program in 2021 compared with previous years.

Study Design: The study design used was a retrospective cohort., Objective: The objective of this study is to determine if intraoperative improvements in sagittal alignment on the operating table persisted on postoperative standing radiographs., Summary of Background Data: Cervical sagittal alignment may be correlated to postoperative outcomes. Since anterior cervical discectomy and fusions (ACDFs) can restore some cervical lordosis through intervertebral grafts/cages, it is important to understand if intraoperative radiographic measurements correlate with persistent postoperative radiographic changes., Materials and Methods: Patients undergoing elective primary ACDF were screened for the presence of lateral cervical radiographs preoperatively, intraoperatively, and postoperatively. Patients were excluded if their first postoperative radiograph was more than 3 months following the procedure or if cervical lordosis was not able to be measured at each time point. Paired t -tests were utilized to compare differences in measurements between time points. Statistical significance was set at P < 0.05., Results: Of 46 included patients, 26 (56.5%) were female, and the mean age was 55.2 ± 11.6 years. C0-C2 lordosis significantly increased from the preoperative to intraoperative time point (delta [Δ] = 4.49, P = 0.029) and significantly decreased from the intraoperative to postoperative time period (Δ = -6.57, P < 0.001), but this resulted in no significant preoperative to postoperative change (Δ = -2.08, P = 0.096). C2 slope decreased from the preoperative to the intraoperative time point (Δ = -3.84, P = 0.043) and significantly increased from the intraoperative to the postoperative time point (Δ = 3.68, P = 0.047), which also resulted in no net change in alignment between the preoperative and postoperative periods (Δ = -0.16, P = 0.848). There was no significant difference in the C2-C7 SVA from the preoperative to intraoperative (Δ = 0.85, P = 0.724) or intraoperative to postoperative periods (Δ = 2.04, P = 0.401); however, the C2-C7 SVA significantly increased from the preoperative to postoperative period (Δ = 2.88, P = 0.006)., Conclusions: Intraoperative positioning predominantly affects the mobile upper cervical spine, particularly C0-C2 lordosis and C2 slope, but these changes do not persist postoperatively., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Craniovertebral Junction and Spine.)

Study Design: The study design is a retrospective cohort study., Objective: To compare patient-reported outcomes between patients with mild versus moderate-to-severe myelopathy following surgery for cervical spondylotic myelopathy (CSM)., Summary of Background Data: Recent studies have demonstrated that decompression for CSM leads to improved quality of life when measured by patient-reported outcomes. However, it is unknown if preoperative myelopathy classification is predictive of superior postoperative improvements., Materials and Methods: A retrospective review of patients treated surgically for CSM at a single institution from 2014 to 2015 was performed. Preoperative myelopathy severity was classified according to the modified Japanese Orthopaedic Association (mJOA) scale as either mild (≥15) or moderate-to-severe (<15). Other outcomes included neck disability index (NDI), 12-item short-form survey (SF-12), and visual analog scale (VAS) for arm and neck pain. Differences in outcomes were tested by linear mixed-effects models followed by pairwise comparisons using least square means. Multiple linear regression determined whether any baseline outcomes or demographics predicted postoperative mJOA., Results: There were 67 patients with mild and 50 patients with moderate-to-severe myelopathy. Preoperatively, patients with moderate-to-severe myelopathy reported significantly worse outcomes compared to the mild group for NDI, Physical Component Score (PCS-12), and VAS arm ( P = 0.031). While both groups experienced improvements in NDI, PCS-12, VAS Arm and Neck after surgery, only the moderate-to-severe patients achieved improved mJOA (+3.1 points, P < 0.001). However, mJOA was significantly worse in the moderate-to-severe when compared to the mild group postoperatively (-1.2 points, P = 0.017). Both younger age ( P = 0.017, β -coefficient = -0.05) and higher preoperative mJOA ( P < 0.001, β -coefficient = 0.37) predicted higher postoperative mJOA., Conclusions: Although patients with moderate-to-severe myelopathy improved for all outcomes, they did not achieve normal absolute neurological function, indicating potential irreversible spinal cord changes. Early surgical intervention should be considered in patients with mild myelopathy if they seek to prevent progressive neurological decline over time., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Craniovertebral Junction and Spine.)

Purpose: To analyze graduating U.S. orthopaedic resident case logs to determine temporal trends in knee and shoulder arthroscopic case volumes, as well as changes in the variability of caseload volumes since the implementation of Accreditation Council for Graduate Medical Education (ACGME) minimum case requirements ("case minimums") in 2013., Methods: We abstracted ACGME-published case log data for all U.S. orthopaedic surgery residents who graduated from 2007 to 2013 (before implementation of case minimums) and from 2014 to 2019 (after implementation). Using a case-control study design, we compared mean numbers of arthroscopic knee and shoulder cases reported per resident between the 2 time periods by using unpaired 2-tailed t tests. P values < .05 were considered significant., Results: The mean number of arthroscopy knee cases reported by residents decreased from 164 before implementation of case minimums to 107 after implementation ( P < .001). The mean number of shoulder cases decreased similarly from 98 to 66 ( P < .001). Among residents with caseload volumes in the 90th percentile ("high-volume caseloads") the decrease was greatest, with 38% fewer knee cases and 41% fewer shoulder cases logged. The ratio of the number of cases in the 90th percentile of caseload to the number in the 10th percentile decreased significantly after implementation of case minimums ( P < .001)., Conclusions: After implementation of ACGME case minimums in 2013, the numbers of arthroscopic knee and shoulder cases reported by graduating U.S. orthopaedic surgery residents decreased significantly. The disparity between the number of cases that constitutes a high-volume caseload and the number that constitutes a low-volume caseload narrowed, suggesting greater uniformity in resident exposure to these procedures across training programs., Level of Evidence: Level III, retrospective comparative study., (© 2020 by the Arthroscopy Association of North America.
