Survivorship and Clinical Outcomes of Reverse Total Shoulder Arthroplasty in Patients with Large Glenoid Defects Using the Stilting Technique and a Baseplate with Central Ingrowth Cage and Peripheral Locking Screws.

BACKGROUND: Stilting is a novel technique used in reverse shoulder arthroplasty (RSA) in patients with significant glenoid bone loss. This technique utilizes peripheral locking screws placed behind an unseated portion of the baseplate, to transmit forces from the baseplate to the cortical surface of the glenoid, without the need for bone grafting. The stilted screw, once locked, provides a fixed angle point of support for an unseated aspect of a baseplate. The primary advantages of this technique are reduced cost compared to a custom implant and reduced operative time compared to bone grafting. METHODS: We conducted a retrospective, non-randomized, comparative cohort study of 41 patients underwent primary Reverse Shoulder Arthroplasty (RSA) using the Stilting Technique with the Exactech Equinoxe Reverse System (Gainesville, FL, USA) at a single, academic center from the years 2004-2021. Exclusion criteria included age under 18 or over 100, and oncologic or acute fracture RSA indications. Operative data was documented, including implant records, percent baseplate seating, and operative duration. Survivorship was compared among primary stilted-RSA (n=41), bone graft-RSA (n=42), and non-stilted/non-bone grafted RSA (n=1,032) within our institutional shoulder arthroplasty database. A radiographic examination of baseplate failure was also conducted across the study groups. Postoperative functional outcomes were compared in a matched analysis involving patients with a minimum 2-year follow-up between stilted patients and a non-stilted/non-bone grafted control group for primary RSA. RESULTS: All Stilted-RSA cases utilized metal augments and demonstrated a mean baseplate seating of 61% (range 45-75%). For stilted RSAs, survivorship was 100% and 92.6% at 2- and 5-years, compared to 98.3% and 94.6% for non-stilted/non-bone grafted and 96.3% and 79.5% for bone-grafted RSAs (p=0.042). At 5-years, the baseplate-related failure rates were greater in the stilted (7.4%) and the bone-grafted (9.3%) cohorts compared with the non-stilted/non-bone grafted cohort (1.1%, p<0.001). The mean time to baseplate failure was 30 months for stilted RSA. Functional outcomes for primary RSA were statistically similar between stilted and non-stilted patients, including range of motion, Constant, ASES, SST, UCLA, and SPADI scores. CONCLUSION: The stilted-RSA cohort exhibited noninferior revision and baseplate failure rates to that of bone-grafted RSA. This suggests that stilting may be a viable technique for patients undergoing primary RSA with significant glenoid deformity.

The Student You Know: Orthopedic Surgery Home Program Match Rates and Geographic Relationships Before and After COVID-19.

OBJECTIVE: In March 2020, COVID-19 was declared a pandemic by the World Health Organization. This led to the outright cancellation of away rotations and in person residency interviews for the class of 2021. This study aims to identify the geographic relationships in the orthopedic match and further explore COVID-19's effect on these geographic relationships. Furthermore, we aim to compare the home program match rates before and after COVID-19. SETTING: Southern Illinois University School of Medicine, Department of Orthopedic Surgery (tertiary, university-based). DESIGN AND PARTICIPANTS: Residency websites and social media sites were used to record basic residency information as well as each resident's year, matriculated medical school, and matriculated medical school geographic data. This information was used to evaluate the proportion of orthopedic residents from "home program" medical schools and evaluate the geographic relationship of matched orthopedic residents. 202 Orthopedic residencies were initially identified and 134 allopathic and nonmilitary residency programs met the inclusion criteria. In all, 3253 of the 3931 (82.7%) current U.S orthopedic residents were included in the analysis. RESULTS: In the 4 orthopedic surgery residency classes before the pandemic (2017-2020), 21.8% of residency slots were filled by home program students. During the pandemic match cycle (2021), this number jumped to 28.2% (p < 0.0006). The increase was observed consistently across residency subgroup analysis: class size, doximity rank, and doximity research rank. Correspondingly, there was a statistically significant increase from 34.7% (2017-2020) to 39.3% (2021) (p = 0.0318) in residencies matching with same state medical students. Regional trends stayed consistent. Our study showed that residency programs matched applicants who went to same region medical schools during the 2020 to 2021 cycle at nearly the exact same rate as they did pre-pandemic (63.6%, up from 63.3%). CONCLUSIONS: Our study demonstrates that despite widespread virtual away rotations and virtual open houses, residency programs showed an increased preference for their home program students. This trend was significant and widespread, highlighting the generalized nationwide hesitation of both residency programs and students on the virtual interview process.

Anterior Scalene Muscle Block Response Predicts Outcomes Following Thoracic Outlet Decompression.

BACKGROUND: There is no definitive objective measure for diagnosis of thoracic outlet syndrome (TOS), and functional capacity testing on standardized rehabilitation exercises before and after an anterior scalene muscle block (ASMB) has the potential to serve as a predictor of response to surgery and to improve diagnostic accuracy in these cases. METHODS: Patients evaluated for TOS underwent ASMB as a diagnostic test and were retrospectively reviewed. Functional capacity scores were recorded for patients performing repetitive motion exercises immediately before ASMB, 15 minutes after ASMB, and at a minimum of 6 weeks after thoracic outlet decompression (TOD). The primary outcome of interest was correlation between the pre- to post-ASMB difference and the pre-ASMB to postoperative difference with respect to 3 functional work capacity scores. RESULTS: The average change in time-to-fatigue and work product between pre- and post-ASMB of all exercises was an increase of 39.5% and 53.8%, respectively. The greatest pre-ASMB to post-TOD difference was seen for the Extremity Abduction Stress Test with an average improvement of 109.7% and 150.4% for time-to-fatigue and work product, respectively. The degree of percent improvement post-ASMB correlated positively with the degree of percent improvement post-TOD for all exercises with respect to work product and time-to-fatigue. CONCLUSIONS: Patient response to ASMB as measured by functional capacity on rehabilitation exercises predicted objective functional outcomes following TOD. Post-ASMB outcomes correlated with post-TOD outcomes. The ASMB can be used to assist in diagnosing TOS and provide a surrogate for expectation in patients considering undergoing neurogenic TOD.

Plate-Assisted Bone Segment Transport Versus Precice Bone Transport Nail.

SUMMARY: Management of segmental long bone defects is a complex and challenging undertaking for orthopaedic surgeons. These defects can be encountered in cases of high-energy trauma, tumor resection, or infection, and they are often associated with significant soft tissue injury. Traditional approaches of bone transport rely on external fixation and principles of distraction osteogenesis. Plate-assisted bone segment transport (PABST) using the Precice limb lengthening nail has been adapted for use in bone transport with the use of a plate in an effort to eliminate the need for external fixation and its associated complications. Recently, the arrival of the Precice Bone Transport (PBT) System intramedullary nail eliminates the need for plating and some of the problems encountered in PABST; however, it also introduces some new issues. PABST and the PBT nail have become viable alternatives to bone transport using a frame; however, each has its own unique set of advantages and disadvantages. Although the problems of using external fixation devices are eliminated with these techniques, there is less forgiveness in execution and very little chance of correcting as the transport is underway. The arrival of the PBT nail does not eliminate the need for PABST as seen by the difficulty maintaining alignment in short metaphyseal segments. This review reflects the current state of these methods based on available evidence; however, optimization of the protocol for transport using PABST and the PBT nail will require additional cases and data.

Perioperative Pain Management in Hand and Upper Extremity Surgery.

Perioperative pain management in surgery of the hand and upper extremity relies on a multimodal approach involving systemic, local, and presurgical considerations. A pain management plan should be tailored to each patient. Management of pain of patients undergoing upper extremity surgery begins before surgical intervention and continues postoperatively. Patient education, setting expectations, psychological interventions, and addressing risk factors associated with postoperative pain are critical to successful pain management. Intraoperative anesthesia is accomplished via a variety of means. Cryotherapy, transcutaneous electrical nerve stimulation, acupuncture, massage, and localized heat are used in concert with pharmacologic therapies postoperatively to continue pain management.

Evaluating clerkship competency without exams.

BACKGROUND: Using examination scores for grading clerkship threatens students' engagement at a time when clinical immersion is critical for socialising into medicine. Narratives of student performance, composed during training by multiple preceptors across diverse settings, may be used to judge competence instead. Preceptor commentary is not trusted as a basis for grading, but the alignment between performance narratives and examination scores has not yet been investigated. METHODS: Performance data were gathered retrospectively from five cohorts of internal medicine clerkship students at one institution. The correlation between end-of-rotation examination scores and the grading committee's ratings of student competency based on preceptors' comments was examined. Patterns in the performance narratives of high- and low-scoring students were also explored. RESULTS: The grading committee's narrative-based ratings of student competence were correlated with examination scores. The majority of preceptors' comments were positive and professionalism-oriented, although students who scored lowest on exams received fewer comments overall and more recommendations for improvement than their highest-scoring peers. Recommendations for the lowest-scoring students equally emphasised knowledge, clinical skill and professionalism, whereas recommendations to highest-scoring students emphasised knowledge and clinical skill at more than twice the rate of professionalism. DISCUSSION: Clerkship preceptors' narratives of student performance can inform competency judgements that are grounded in actual workplace learning and are related to the independent examination of knowledge and clinical performance. Using performance narratives as the basis for grading may be a viable approach to balancing learning and assessment needs during core clerkship block rotations.

Verification of Proficiency in Basic Skills for PGY-1 Surgical Residents: 10-Year Update.

OBJECTIVE: The American College of Surgeons and the Association of Program Directors in Surgery developed a curriculum in 2001 that involved instructional modules for 11 basic surgical skills and a standardized Verification of Proficiency (VOP) evaluation instrument. Our institution continues to employ a modified version of this curriculum and the purpose of this study was to provide a 10-year update on our VOP evaluation instrument used to assess postgraduate year 1 (PGY-1) residents on surgical skills. DESIGN: All PGY-1 surgical residents over the past 10 years at our institution have completed the American College of Surgeons/the Association of Program Directors in Surgery-adapted basic surgical skills curriculum and VOP assessment. Retrospective analysis of VOP data for all residents was subjected to statistical analysis for internal validity and level of correlation. SETTING: Department of Surgery at Southern Illinois University School of Medicine located in Springfield, Illinois. PARTICIPANTS: All PGY-1 surgical residents (per year: 4 general surgery, 3 orthopedic surgery, 2 plastic surgery, 2 urology, 2 ENT, 1 vascular surgery, and 1 neurosurgery) over the past 10 years. RESULTS: One hundred and thirty five residents underwent VOP evaluation over 10 years; 92 (68%) failed at least 1 module and 40 (30%) failed at least 2 modules. Residents who failed to demonstrate proficiency were mandated to complete remediation and retested until their scores were considered proficient. Performance on checklist items showed moderate internal consistency (⍺ ≥ 0.50) on 9 of 11 modules. Poor internal consistency (⍺ < 0.30) was noted for overall proficiency across all modules. Combined performance on checklist items and economy of time and motion demonstrated significant positive correlation (p < 0.05) with overall proficiency in every module. CONCLUSIONS: The VOP instrument offers an internally valid means of assessing distinct basic skills of PGY-1 residents at basic surgical skills. The instrument provides critical formative and summative feedback on surgical skill performance to trainees.

Surgeon Agreement on the Presence of Pathologic Anterior Instability on Shoulder Imaging Studies.

BACKGROUND: In the setting of anterior shoulder instability, it is important to assess the reliability of orthopaedic surgeons to diagnose pathologic characteristics on the 2 most common imaging modalities used in clinical practice: standard plain radiographs and magnetic resonance imaging (MRI). PURPOSE: To assess the intra- and interrater reliability of diagnosing pathologic characteristics associated with anterior shoulder instability using standard plain radiographs and MRI. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: Patient charts at a single academic institution were reviewed for anterior shoulder instability injuries. The study included 40 sets of images (20 radiograph sets, 20 MRI series). The images, along with standardized evaluation forms, were distributed to 22 shoulder/sports medicine fellowship-trained orthopaedic surgeons over 2 points in time. Kappa values for inter- and intrarater reliability were calculated. RESULTS: The overall response rate was 91%. For shoulder radiographs, interrater agreement was fair to moderate for the presence of glenoid lesions (κ = 0.49), estimate of glenoid lesion surface area (κ = 0.59), presence of a Hill-Sachs lesion (κ = 0.35), and estimate of Hill-Sachs surface area (κ = 0.50). Intrarater agreement was moderate for radiographs (κ = 0.48-0.57). For shoulder MRI, interrater agreement was fair to moderate for the presence of glenoid lesions (κ = 0.44), glenoid lesion surface area (κ = 0.35), Hill-Sachs lesion (κ = 0.33), Hill-Sachs surface area (κ = 0.28), humeral head edema (κ = 0.41), and presence of a capsulolabral injury (κ = 0.36). Fair agreement was found for specific type of capsulolabral injury (κ = 0.21). Intrarater agreement for shoulder MRI was moderate for the presence of glenoid lesion (κ = 0.59), presence of a Hill-Sachs lesion (κ = 0.52), estimate of Hill-Sachs surface area (κ = 0.50), humeral head edema (κ = 0.51), and presence of a capsulolabral injury (κ = 0.53), and agreement was substantial for glenoid lesion surface area (κ = 0.63). Intrarater agreement was fair for determining the specific type of capsulolabral injury (κ = 0.38). CONCLUSION: Fair to moderate agreement by surgeons was found when evaluating imaging studies for anterior shoulder instability. Agreement was similar for identifying pathologic characteristics on radiographs and MRI. There was a trend toward better agreement for the presence of glenoid-sided injury. The lowest agreement was observed for specific capsulolabral injuries.

The journeys of three ASPIRE winning medical schools toward excellence in student assessment.

Introduction: ASPIRE Excellence Awards in Student Assessment are offered to medical schools with innovative and comprehensive assessment programmes adjudged by international experts, using evidence-based criteria. The journeys of three ASPIRE-winning medical schools toward "assessment excellence" are presented. These schools include Aga Khan University Medical College (AKU-MC), Pakistan, Southern Illinois University School of Medicine (SIUSOM), USA, and University of Leeds School of Medicine, UK. Methods: The unfolding journeys highlighting achievements, innovations, and essential components of each assessment programme were compared to identify differences and commonalities. Results: Cultural contextual differences included developed-versus-developing country, east-west, type of regulatory bodies, and institutional-versus-national certifying/licensing examinations, which influence curricula and assessments. In all, 12 essential commonalities were found: alignment with institutional vision; sustained assessment leadership; stakeholder engagement; communication between curriculum and assessment; assessment-for-learning and feedback; longitudinal student profiling of outcome achievement; assessment rigor and robustness; 360° feedback from-and-to assessment; continuous enrichment through rigorous quality assurance; societal sensitivity; influencing others; and a "wow factor." Conclusions: Although the journeys of the three medical schools were undertaken in different cultural contexts, similar core components highlight strong foundations in student assessment. The journeys continue as assessment programmes remain dynamic and measurement science expands. This article may be helpful to other institutions pursuing excellence in assessment.

Relationships Matter: Enhancing Trainee Development with a (Simple) Clerkship Curriculum Reform.

PROBLEM: The traditional clerkship model of brief encounters between faculty and students results in reduced meaningful learning opportunities due to the lack of a relationship that enables repeated observation, supervisor feedback, trust formation, and growth. INTERVENTION: Clinical clerkships at our institution were restructured to decrease fragmentation of supervision and foster an educational alliance between faculty and student. A mixed-methods approach was used to study the impact of this curriculum reform on the student experience in the obstetrics and gynecology clerkship. Student participation in patient care was assessed by comparing the number of common obstetric procedures performed before and after clerkship reform. Separate qualitative analyses of comments from student surveys and a faculty focus group revealed themes impacting student involvement. The supervisor-trainee relationship was further investigated by analysis of "rich picture" discussions with students and faculty. CONTEXT: Clerkships in the 3rd year of our 4-year undergraduate medical curriculum were converted from an experience fragmented by both didactic activities and multiple faculty supervisors to one with a single supervisor and the elimination of competing activities. OUTCOMES: Students in the revised clerkship performed twice the number of obstetric procedures. Objective measures (United States Medical Licensing Examination Step 1 scores, receiving clerkship honors, self-reported interest in obstetrics, and gender) did not correlate with the number of procedures performed by students. Qualitative analysis of student survey comments revealed that procedure numbers were influenced by being proactive, having a supervisor with a propensity to teach (trust), and contextual factors (busy service or competition with other learners). Themes identified by faculty that influenced student participation included relationship continuity; growth of patient care skills; and observed student engagement, interest, and confidence. The quality of the relationship was cited by both students and faculty as a factor influencing meaningful clinical participation. Discussions of "rich pictures" drawn by students and faculty revealed that relationships are influenced by continuity, early alignment of goals, and the engagement and attitude of both student and faculty. LESSONS LEARNED: Clinical curricular reforms that strengthen the continuity of the supervisor-trainee relationship promote mutual trust and can result in a more meaningful training experience in less time. Reciprocal engagement and early alignment of goals between supervisor and trainee are critical for creating a positive relationship.

Novel Surgical Approach to Segmental Bone Transport Using a Magnetic Intramedullary Limb Lengthening System.

Posttraumatic bone defects (BDs) remain a difficult complication for orthopaedic surgeons. Surgical goals in these reconstructive cases are to create stable limb fixation, maintain limb length, and provide adequate soft-tissue coverage. Historically, surgical approaches in these cases have required the use of an external fixator, which is associated with several postoperative complications. A plate-assisted bone segment transport (PABST) technique using a magnetic limb lengthening system eliminates the need for an external fixator and is effective for these reconstructive cases. A 51-year-old male patient presented as a category I trauma after a motorcycle collision. Osseous injury was defined as Gustilo-Anderson type IIIB distal tibia and fibula fracture (AO 42-C2). After fixation failure, the PABST technique was performed using a magnetic intramedullary limb lengthening system. Radiographic union was achieved 18 months postoperatively. This innovative surgical technique is effective in treating posttraumatic BDs without the need for limb shortening or the use of an external fixator. PABST has the potential to decrease postoperative complications in BD reconstructive cases using all-internal technology designed for limb lengthening. PABST, in this instance, uses a magnetic intramedullary nail that is controlled with a hand-held external remote to allow for precise, adjustable, and bidirectional bone segment transport.

Postoperative Radiographic Assessment of the Vega Posterior-Stabilized TKA.

Different biomechanical designs are incorporated into various total knee arthroplasty (TKA) implants. The posterior-stabilized prosthesis design utilizes a polyethylene post and femoral cam in place of the posterior cruciate ligament. This produces a more stable component interface, increased range of motion, and potentially a less technical procedure. This study aimed to assess the short-term (>2 year) outcomes associated with the Vega System posterior-stabilized knee prosthesis (Aesculap Implant Systems, Center Valley, Pennsylvania) based on postoperative radiographs using the Knee Society Roentgenographic Evaluation and Scoring System (KSRESS). Thirty-seven TKA patients who had received the Vega posterior-stabilized knee prosthesis and had postoperative radiographs at each follow-up for a minimum of 2 years were enrolled, retrospectively. Two independent observers evaluated the radiographs using KSRESS. Descriptive statistics were used to analyze the data. The average age and body mass index of patients enrolled was 67 years (range, 51-89 years) and 38.5 kg/m(2) (range, 21.2-54 kg/m(2)), respectively. Patients had radiographic follow-up for an average of 36 months (range, 24-58 months). Comparison between first and last available postoperative radiographs revealed a stable femoral and tibial interface with no significant change in prosthesis alignment over the follow-up period. Assessment of the short-term survivorship of the Vega posterior-stabilized prosthesis using KSRESS revealed no significant change in alignment after 2 years of follow-up; however, mid- to long-term studies assessing this junction are needed. A future prospective study using KSRESS in combination with clinical follow-up is recommended to allow comparison of the Vega posterior-stabilized to other prostheses.
