Polyvinyl Alcohol Hydrogel Hemiarthroplasty of First Metatarsophalangeal Joint Hallux Rigidus.

Background Hallux rigidus (HR) is the most common arthritic condition of the foot. Although first metatarsophalangeal joint (MTPJ) arthrodesis has been the historical gold-standard treatment, polyvinyl alcohol (PVA) hydrogel implants have gained popularity as a joint-sparing technique. However, recent studies have shown variable failure rates of PVA hydrogel implants. The purpose of this study was to report the five-year experience with PVA hydrogel implants performed by a single surgeon. Methodology Health records were queried from August 2016 to 2021 for patients who underwent primary PVA hydrogel implant hemiarthroplasty for symptomatic late-stage HR. Patient demographics and postoperative outcomes variables were evaluated. Kaplan-Meier analysis was used to evaluate implant survival. A total of 146 PVA hydrogel implant procedures were performed with a minimum six-month follow-up. Results The majority of patients were female (n = 103, 70.5%), with a mean age of 58.1 (±10.1) years, body mass index of 27.3 (±5.2) kg/m2, and American Society of Anesthesiologists score <3 (n = 131, 89.7%). The majority had stage II or III disease (n = 115, 78.8%). Patients experienced significant improvement in visual analog scale score (p < 0.0001) and hallux dorsiflexion (p = 0.0005). There were 22 (15.1%) complications, including implant subsidence (n = 15, 10.3%), deep infection (n = 6, 4.1%), and hypertrophic ossification (n = 1, 0.7%). Revision surgeries were required in 12.3% (n = 18) of patients at an average of 9.4 (±9.2) months postoperatively. This included nine (6.2%) revision PVA hydrogel implant procedures and nine (6.2%) first MTJP arthrodesis. The one- and two-year survival rates for MTPJ arthrodesis (n = 9) were 95.9% and 86.3%, respectively. Conclusions In the largest single-surgeon series reported, first MTPJ hemiarthroplasty with a PVA hydrogel implant significantly improved pain and hallux dorsiflexion at an average of 14.5 months postoperatively. There was a high two-year survivorship of 86.3% until failure which required first MTPJ arthrodesis. Future studies should be performed to refine the indications for PVA hydrogel implants and identify risk factors.

Mechanism of Injury for Traumatic Mid-Foot Lisfranc Injuries: Impact of the COVID-19 Pandemic.

Background During the COVID-19 pandemic, Americans transitioned away from their normal routines, drove in motor vehicles less, and reduced their physical activity, ultimately influencing the incidence and nature of orthopedic injuries that were operatively managed. The purpose of this study was to evaluate the effect of the COVID-19 pandemic lockdown and subsequent deconditioning on the mechanism of injury and severity of Lisfranc injury. Methods This retrospective study included patients with a traumatic Lisfranc injury who were surgically treated by a foot and ankle fellowship-trained orthopedic surgeon between 2015 and 2021. Electronic health records were queried for patient demographics, mechanism of injury, physical exam findings, and pain scores. Preoperative radiographs were reviewed to grade Lisfranc injuries using the previously described Nunley-Vertullo classification system. Descriptive and univariate statistics were performed to compare 15 patients in the pre-COVID-19 cohort and 15 patients in the post-COVID-19 cohort. Results In the pre-COVID-19 cohort, 80% (n=12/15) of the patients were female, the mean age was 46±15 years, the mean BMI was 29.7±7 kg/m2, and the mean follow-up period was 18.1±12 months. In the post-COVID-19 cohort, 53% (n=8/15) of the patients were female, the mean age was 48.5±17 years, the mean BMI was 31.4±7 kg/m2, and the mean follow-up period was 9.5±4 months. Significantly higher proportions of plantar ecchymosis (n=8/15, 53%), neuropathic pain (n=7/15, 47%), and swelling (n=12/15, 80%) were present in the post-COVID-19 cohort. A low-energy mechanism of injury was sustained by 73% (n=11/15) of the pre-COVID-19 cohort and 80% (n=12/15) of the post-COVID-19 cohort. Lisfranc injuries for the pre-COVID-19 cohort and the post-COVID-19 cohort demonstrated the following classifications: Grade 1 (33%, n=5/15 vs. 40%, n=6/15), Grade 2 (60%, n=9/15 vs. 53%, n=8/15), and Grade 3 (7%, n=1/15 vs. 7%, n=1/15). Conclusion Although a higher proportion of plantar ecchymosis, neuropathic pain, and swelling was observed, there was no association between a low mechanism of injury and a higher grade of Lisfranc injury following the COVID-19 pandemic.

Association of Symptomatic Venous Thromboembolism and BMI in Patients Undergoing Sports Medicine Knee Procedures: A Retrospective Case-Control Study.

BACKGROUND: The purpose of this study was to characterize the prevalence of venous thromboembolism (VTE; including deep vein thrombosis [DVT] and pulmonary embolism [PE]) after sports medicine knee procedures by a single surgeon at an academic institution, identify factors associated with increased risk of VTE, and determine risk factor thresholds for beyond which VTE risk is elevated. HYPOTHESIS: We hypothesized that the prevalence of VTE after sports medicine knee procedures is low, but that increasing weight and body mass index (BMI) would be associated with elevated risk. STUDY DESIGN: Retrospective case-control study. LEVEL OF EVIDENCE: Level 3. METHODS: A retrospective case-control study analyzing sports medicine knee surgeries from 2017 to 2020 was conducted using current procedural terminology codes to identify cases. Optimal cutoff points for specific continuous patient characteristics were calculated to determine elevated risk of postoperative VTE. Overall VTE-free survival was assessed using Kaplan-Meier analysis and Cox proportional hazard regression models. RESULTS: Among the 724 eligible patients, there were 13 postoperative VTE events (1.79% prevalence; 12 DVTs, 1 DVT/PE). Increasing weight and BMI were significant risk factors for postoperative VTE (P = 0.03 and P = 0.04, respectively), with weight >94.7 kg and BMI >27.9 kg/m2 associated with elevated risk in male patients and weight >79.1 kg and BMI >28.1 kg/m2 associated with elevated risk for female patients. Cox regression demonstrated a significantly increased risk of postoperative VTE for male patients with BMI ≥27.9 kg/m2. CONCLUSION: Patients who undergo sports medicine knee surgery with increased weight and BMI are at an elevated risk of postoperative VTE. An individualized approach should be considered for chemoprophylaxis in patients with these risk factors. CLINICAL RELEVANCE: Consider chemoprophylaxis in patients with increased weight and BMI who undergo sports medicine knee surgery since they are at an elevated risk of postoperative VTE.

Outcomes after arthroscopically assisted lower trapezius transfer with Achilles tendon allograft.

BACKGROUND: Lower trapezius tendon transfer is 1 option to improve pain and function with massive irreparable rotator cuff tears. Magnetic resonance imaging (MRI) evaluation of tendon healing with the procedure has not yet been reported. The purpose of this study was to evaluate early tendon transfer healing using postoperative MRI scans and to assess early clinical outcomes in patients after arthroscopically assisted lower trapezius tendon transfer (AALTT) for massive irreparable rotator cuff tears. METHODS: This was a single institution retrospective review of consecutive patients with massive irreparable rotator cuff tears who underwent AALTT with a single surgeon from January 2017 to July 2020 with a minimum 6-month follow-up. Patient information including age, sex, follow-up, prior surgical history, and type of work (sedentary or labor-intensive) was recorded. Preoperative and postoperative range of motion, external rotation strength, presence of a lag sign, and pain visual analog scale data were extracted from medical records. Patient-reported outcomes were extracted from patient charts. Six-month postoperative MRIs were reviewed for tendon transfer healing at both the greater tuberosity and the trapezius-allograft interface. RESULTS: A total of 19 patients met inclusion criteria with average age 56.7 (range, 29-72 years). Of these patients, 17 (89.5%) were male. The average follow-up was 14.6 (range, 6-45) months. Fifteen (78.9%) patients had unsuccessful previous rotator cuff repair. Six-month MRI demonstrated complete healing of the transferred tendon in 17 of 19 patients (89.5%). There were significant improvements in postoperative pain visual analog scale (5.9 ± 2 vs. 1.8 ± 2), ASES score (44.6 ± 18 vs. 71.2 ± 24), and Patient Reported Outcomes Measurement Information System Physical (46.3 ± 6 vs. 51.3 ± 11) and in external rotation motion (10.5 ± 17° vs. 40.5 ± 13°) and strength (2.8/5 ± 1 vs. 4.7/5 ± 0.5) at final follow-up. All patients with a preoperative external rotation lag sign had reversal of their lag sign at final follow-up (15/15). Of 17 work-eligible patients, 13 (76.4%) were able to return to work. CONCLUSION: In this series, AALTT showed a high rate of healing of the transferred tendon on MRI by 6 months postoperatively. The current findings of a high rate of early tendon transfer healing are consistent with the good early and mid-term outcomes that have been observed in AALTT and provide support for surgeon and patient expectations, postoperative rehabilitation, and return to work following AALTT for massive posterior superior rotator cuff tears.

Short-Term Outcomes of Jones-Specific Implant Versus Intramedullary Screw and Plate Fixation for Proximal Fifth Metatarsal Fractures.

Although intramedullary screw fixation is commonly performed for proximal fifth metatarsal fractures, high rates of nonunion, refracture, and hardware prominence have been reported. The Jones Specific Implant (JSI) is a novel surgical implant which contours to the native curvature of the fifth metatarsal allowing for a more anatomic fixation. The purpose of this study was to compare short-term complication rates and outcomes of patients treated with the JSI to other fixation types such as plates and intramedullary screws. Electronic records were queried for adult patients with proximal fifth metatarsal fractures who underwent primary fixation from 2010 to 2021. All patients were treated by a foot and ankle fellowship-trained surgeon with intramedullary screws, plates, or JSI (Arthrex Inc., Naples, FL). Visual analog scale (VAS) and the American Orthopedic Foot and Ankle Score (AOFAS) were recorded and compared using univariate statistics. Eighty-five patients underwent fixation using intramedullary screw (n = 51, 60%), plate (n = 22, 25.9%), or JSI (n = 12, 14.1%) with a mean follow-up of 11.1 ± 14.6 months. The total cohort demonstrated a significant improvement in VAS pain (p < .0001) as well as AOFAS (p < .0001) scores. When comparing the cohort treated with JSI and the cohort treated with all other types of fixation, there were no significant differences in postoperative VAS or AOFAS scores. Only 3 complications, one with JSI (3.5%) required removal of the symptomatic hardware. The JSI is a novel treatment for proximal fifth metatarsal fractures, with similar early outcomes and complication rates when compared with intramedullary screw and plate fixation.

Revision Surgery After Failed Index Synthetic Cartilage Implant Resurfacing for Hallux Rigidus: Single-Surgeon 5-Year Experience.

BACKGROUND: While metatarsophalangeal joint (MTPJ) arthrodesis is regarded as the gold standard treatment option for end-stage hallux rigidus (HR), synthetic cartilage implant (SCI) resurfacing has gained popularity. This study aimed to identify the SCI resurfacing failure rate for a single surgeon, while also comparing clinical outcomes of patients who underwent SCI replacement or MTPJ arthrodesis after failed index SCI resurfacing. METHODS: Health records were queried from 2016 to 2021 for patients with HR who were treated with SCI resurfacing by a single surgeon. Preoperative and postoperative range of motion, visual analog scale (VAS) pain scores, and hallux valgus angles were compared. A subgroup analysis was performed on patients who underwent revision with SCI replacement or MTPJ arthrodesis. SCI replacement included the use of bone graft, bone putty, or a custom 3D printed baseplate to prevent implant subsidence. RESULTS: A total of 219 SCI resurfacing procedures were performed by a single surgeon, including 23 revisions. When analyzing index procedures, an 8.2% revision rate was determined. The revision cohort (n = 23) consisted of 19 female patients and presented with a mean body mass index of 29.5 ± 5 kg/m2, mean age of 52.8 ± 11 years, mean follow-up duration of 22.3 (range, 3-54) months, and mean time to a revision surgery of 12.1 ± 12 (range, 1-50) months. Specifically, 12 procedures resulted in an SCI replacement, while 11 procedures resulted in arthrodesis. While all patients experienced significant improvement in their VAS pain scores (P < .001), the arthrodesis cohort experienced a greater improvement than the SCI revision cohort (P = .04). CONCLUSION: When analyzing SCI revision procedures, MTPJ arthrodesis reduced pain more significantly than SCI replacement. LEVELS OF EVIDENCE: Level IV: Retrospective case series.

Outcomes after bilateral shoulder arthroplasty: a systematic review.

The purpose of this systematic review was to report outcomes after bilateral shoulder arthroplasty including bilateral total shoulder arthroplasty (TSA), bilateral reverse shoulder arthroplasty (RSA), and ipsilateral TSA with contralateral RSA (TSA/RSA). Two reviewers independently performed a PRISMA-guided systematic search using MEDLINE/PubMed, Embase, and Cochrane Database of Systematic Reviews up to May 11, 2021. The databases were queried using the following search terms: (["bilateral" OR "contralateral"] AND "shoulder" AND ["arthroplast∗" OR "replacement"]). A total of 486 titles/abstracts were screened for eligibility and 19 studies were included in the final analysis. Risk of bias was assessed using Methodological Index for Nonrandomized Studies and Modified Coleman Methodology scores. Analysis compared overall results for bilateral shoulder arthroplasty and sub-group analyses compared TSA (all shoulders from bilateral TSA patients and the TSA shoulder in TSA/RSA patients) to RSA (all shoulders from bilateral RSA patients and the RSA shoulder in TSA/RSA patients), first shoulder arthroplasty to second contralateral shoulder arthroplasty, and interval between arthroplasty (IBA) <20 months to IBA ≥20 months. Nineteen studies analyzed bilateral TSA (n = 3), bilateral RSA (n = 7), and TSA/RSA (n = 8). The mean Methodological Index for Nonrandomized Studies was 18 and mean Modified Coleman Methodology Score was 74, with 63.2% of studies demonstrating level III evidence. A total of 2729 patients (30.4% male; mean age 72.2 years, mean follow-up 47.3 months, mean IBA 20 months) were analyzed. Postoperative forward flexion (142.0° vs. 129.6°), external rotation (ER) (42.5° vs. 25.6°), and internal rotation (60% reaching T12-T8 vs 85.7% reaching L3-L1) were higher for TSA when compared to RSA. Patient reported outcome measures such as Constant-Murley (73.2 vs. 59.2), American Shoulder and Elbow Surgeons (87.9 vs. 77.7), and Single Assessment Numeric Evaluation (SANE) (86.9 vs. 67.8) were higher for TSA when compared to RSA. Patients with IBA ≥20 months demonstrated greater ER and patient satisfaction than patients with IBA <20 months. Postoperative complication rates were 15.1% for TSA and 10.6% for RSA, while reoperation and revision rates were 13.7% for TSA and 7.1% for RSA. Bilateral shoulder arthroplasty results in improvements in motion, strength, pain, function, and high satisfaction. Bilateral TSA is associated with greater improvement in motion and function than bilateral RSA but higher complication, reoperation, and revision rates. IBA ≥20 months is associated with greater ER and satisfaction than IBA <20 months.

Bilateral Achilles Tendon Ruptures in the NFL.

Background: Achilles tendon ruptures (ATR) can have devastating results for athletes in the National Football League (NFL). While many studies have examined the effects of an ipsilateral ATR, there are no reports on the impact of bilateral ATRs on NFL athlete performance. Methods: Publicly available online injury data for NFL athletes who sustained bilateral ATRs between the start of the 2007 season and the start of the 2021 season were queried using online news and sports analysis web sources. Results: After applying inclusion and exclusion criteria, 5 NFL athletes were identified. The findings demonstrated a significant difference in age at the time of each rupture (27.8 vs 30.4 years, P < .01) along with a decreasing trend in the number of Pro Bowl nominations following successive ATRs (P = .027). There were no differences reported for the duration and number of games missed during either rehabilitation period following an ATR. Upon analyzing defensive NFL athletes, forced fumbles was the only performance metric that significantly changed across successive ATRs. Conclusion: Overall, bilateral ATRs can adversely impact an NFL player's performance and further research should be performed to continue analyzing the effects of bilateral ATRs on these athletes.Level of Evidence: 4.

3D-Printed Total Talus Replacement After Free Vascularized Medial Femoral Condyle Osteocutaneous Flap for Avascular Necrosis of the Talus Leads to Poor Clinical Outcomes: A Case Series.

INTRODUCTION: Avascular necrosis (AVN) of the talus is 1 of the most difficult foot and ankle pathologies to diagnose and manage. The purpose of this study was to report on the functional outcomes of 3D-printed total talus replacement (TTR) in 2 patients with talar AVN who both underwent a failed revascularization. METHODS: This is a case series of 2 patients with TTR after a failed revascularization and a comparison group of 25 patients with primary TTR. Clinical and functional outcomes are used to compare both groups. RESULTS: Patient 1 had a postrevascularization Visual Analogue Scale (VAS) pain score of 9. Imaging showed failure of the medial femoral condyle to incorporate with talar fragmentation. Patient underwent TTR at 5 months postoperatively. At 2 years postoperatively, the patient underwent a cavovarus foot reconstruction; however, patient continued to suffer from ankle pain (VAS 6) and ultimately underwent below knee amputation at 3 years after the TTR. Patient 2 initially underwent a core decompression for a talar bone infarct followed by revascularization procedure at 6 months postoperatively due to persistent pain and bony infarcts. At 18 months postrevascularization, the patient had a VAS pain score of 9 and progression of the AVN. She underwent a TTR. At 1-year follow-up, the VAS pain score was 8. Both patients had an ankle plantarflexion of 30° at their last TTR follow-up. The comparison group consisted of 25 patients who underwent 3D-printed TTR with mean postoperative VAS score and ankle plantarflexion of 3.7° and 41.8°. CONCLUSION: Patients 1 and 2 demonstrated reduced plantarflexion and ankle motion after TTR relative to the comparison group which improved in both physical assessments. The first patient needed a below knee amputation for persistent pain. Patient 2 showed less improvement in all the foot and ankle outcome scores as compared with the primary TTR group. LEVEL OF EVIDENCE: Level V: Retrospective case series.

Rates of Operative Management of Midshaft Clavicle Fracture in Adolescents Have Increased in Florida between 2005 and 2014.

Background: It is not known if the adult literature on midshaft clavicle fracture treatment with open reduction internal fixation (ORIF) has influenced injury management in adolescents. Purpose: We sought to longitudinally evaluate the rates of operative management of adolescent midshaft clavicle fractures in the state of Florida. Methods: We conducted a retrospective review of data from the following Healthcare Cost and Utilization Project databases: the State Inpatient Database, the State Ambulatory Surgery and Services Database, and the State Emergency Department Database. Patients in Florida ages 10 to 18 years with midshaft clavicle fractures between 2005 and 2014 were identified along with data on age, sex, race/ethnicity, insurance type, treatment, and income percentile. We reviewed the data to identify trends in the rates of operative management of midshaft clavicle fractures. We then compared the rates of operative management between the first 3 years and the most recent 3 years (2005-2007 vs 2012-2014). Various demographic and socioeconomic factors were compared between patients treated with and without surgery. Descriptive statistics as well as univariate and multivariate analyses were performed. Results: There were 4297 midshaft clavicle fractures in adolescents identified between 2005 and 2014, and 338 (7.8%) of these fractures underwent operative management. There was a significant increase in the rate of operative management; it increased from 4.3% (n = 59) of the 1373 clavicle fractures that occurred between 2005 and 2007 to 11.2% (n = 130) of the 1164 clavicle fractures that occurred between 2012 and 2014. Patients with commercial insurance and patients who were older were more likely to undergo ORIF. Patients with Medicaid were more likely to undergo ORIF between 2012 and 2014 compared with patients with Medicaid between 2005 and 2007. Conclusions: Operative management rates of adolescent midshaft clavicle fractures have significantly increased in Florida over a decade; additional research is needed to understand these findings.

Time to publication for orthopaedic surgery peer-reviewed journals: A cross-sectional bibliometric analysis.

Background: The dissemination of research and evidence-based medicine is critical to advancing science and improving clinical practice. The purpose of this study was to evaluate the timing and associated factors of the publication process for the most influential orthopaedic surgery research journals. Methods: After analyzing 25 orthopaedic surgery journals with the highest impact factors, 14 journals provided the necessary information for data analysis. A minimum of three consecutive issues per journal from 2021 were collected for review. Within each issue, all articles were included except for reviews, commentaries, replies, letters to the editor, and invited articles. The publication times for received to accepted (RA), received to published in press (RP1), and received to published in print (RP2) were retrieved and compared. Journal impact factor, specialty, and article level of evidence were recorded. Results: A total of 1040 articles were included with a mean number of 74.3 ± 38 (range, 35-182) articles analyzed per journal. The mean impact factor for the 14 journals was 3.6 ± 1 (range, 2.5-5.8). The overall median duration of time for RA, RP1, and RP2 were 119 (IQR, 78-165) days, 157 (IQR, 102-216) days, and 291 (IQR, 243-378) days across all 14 journals, respectively. Journal of Arthroplasty demonstrated the shortest median duration of time for RA and RP1, while International Orthopaedics demonstrated the shortest median duration of time for RP2. Clinical Journal of Sport Medicine demonstrated the longest median duration of time for RA and RP2, while the American Journal of Sports Medicine demonstrated the longest median duration of time for RP1. Level three studies, which included retrospective case-control and cohort study designs, demonstrated the shortest publication times, while sports medicine journals demonstrated the longest publication times for all periods. Conclusion: There was substantial variation in publication times across orthopaedic surgery journals which may impact accessibility to clinical insights.

Orthopaedic Foot and Ankle Surgery Leadership Trends: A Cross-Sectional Study of Fellowship Directors and Division Chiefs.

Background: In orthopaedic surgery departments, foot and ankle fellowship directors are tasked to create a robust clinical curriculum for trainees, while division chiefs manage the division's delivery of patient care. The primary aim of this study was to describe characteristics of foot and ankle surgery fellowship directors and division chiefs in an effort to recognize trends or disparities in leadership traits. Methods: The American Orthopaedic Foot and Ankle Society (AOFAS) fellowship directory for 2021 to 2022 was reviewed for AOFAS-recognized fellowship programs in the United States. Between March 2021 and June 2021, 48 fellowship directors and 23 publicly recognized division chiefs were administered an electronic survey to collect demographic, educational, and professional data. Univariate and bivariate statistical analyses were performed. Results: A total of 42 of the 48 (87.5%) fellowship directors and 18 of the 23 (78.3%) division chiefs responded to the questionnaire. Of the 48 fellowship directors, 45 (93.8%) were male, 43 (89.6%) identified as Caucasian, their average age at leadership appointment was 42.6 ± 7.5 (range, 32-70) years, and the average time between fellowship graduation and leadership appointment was 9.9 ± 7.8 (range, 0-36) years. Of the 23 chiefs, 22 (95.7%) were male, 20 (87.0%) identified as Caucasians, their average age at leadership appointment was 41.7 ± 7.8 (range, 32-53) years, and the average time between fellowship graduation and leadership appointment was 9.8 ± 6.8 (range, 2-21) years. The average H-index for the chiefs was greater than that of the fellowship directors (18.4 vs 13.4, P = .0373) when controlling for years of training>. Conclusion: The majority of current leaders identify as middle-age Caucasian males, demonstrate high research productivity, and have attended a select number of the same residency and fellowship training programs. By demonstrating the lack of diversity within foot and ankle surgery leadership, this study serves as a call to action for making inclusivity a priority.Levels of Evidence: Level IV: Cross-sectional study.

Achilles: Failed Acute Repair.

In this chapter the authors discuss complications, how to avoid them, and ultimately how to manage complications with your patients.

Leadership Trends in Shoulder and Elbow Surgery Fellowship Directors: A Cross-sectional Study.

INTRODUCTION: We aimed to describe the demographic and professional backgrounds of current shoulder and elbow fellowship directors. METHODS: The American Shoulder and Elbow Surgeons (ASES) 2021 to 2022 Fellowship Directory was reviewed to identify the 31 ASES-recognized US fellowship programs. Demographic and other data were obtained through an electronic survey and publicly available online resources from February 28, 2021, to March 5, 2021. RESULTS: Of the 31 fellowship directors, 97% (30) identified as male and 74% (23) as White, the mean age was 53 ± 7 years, and the mean Scopus h-index was 24.2 ± 13. Almost all (95%) held ASES committee leadership appointments in at least one committee. The mean time from completion of most recent fellowship to fellowship director appointment was 7.3 ± 6 years. About two-thirds of fellowship directors trained at one of five fellowship programs: Columbia University (n = 7), California Pacific Orthopaedics (n = 4), Washington University in St. Louis (n = 3), Mayo Clinic (n = 3), and Hospital for Special Surgery (n = 2). DISCUSSION: ASES fellowship directors share similar demographic and professional characteristics with high levels of research productivity and involvement in orthopaedic societies. There is a lack of diversity in shoulder and elbow fellowship directors, highlighting a need for priority consideration of this disparity by leaders in the field.

Three-Dimensional-Printed Lesser Metatarsal Replacement: The First Case Report.

Different procedures have been reported for severe and recurrent lesser toes deformity. These included DuVries metatarsophalangeal joint arthroplasty, resection arthroplasty, partial proximal phalangectomy, syndactylization, or lesser toe amputation. In the presence of a failed metatarsal head resection, the surgeon is faced with limited salvage options including Hoffman procedure or lesser toe amputation. The 3D printing technology has allowed orthopaedic surgeons to expand the therapeutic arsenal to address challenging situations. We herein present the first case of 3D-printed second lesser metatarsal replacement performed after a failed second metatarsal head resection.Level of Evidence: V.

Influence of medical comorbidity and surgical indication on total elbow arthroplasty cost of care.

BACKGROUND: Movement toward providing value-based musculoskeletal care requires understanding the cost associated with surgical care as well as the drivers of these costs. The aim of this study was to investigate the effect of common medical comorbidities and specific total elbow arthroplasty (TEA) indications on reimbursement costs throughout the 90-day TEA episode of care. The secondary aim was to identify the drivers of these costs. METHODS: Administrative health claims for patients who underwent orthopedic intervention between 2010 and 2020 were queried using specific disease classification and procedural terminology codes from a commercially available national database of 53 million patients. Patients with commercial insurance were divided into various cohorts determined by different surgical indications and medical comorbidities. The reimbursement costs of the surgical encounter, 89-day postoperative period, and total 90-day period in each cohort were evaluated. The cost drivers for the 89-day postoperative period were also determined. Analyses were performed using descriptive statistics and the Kruskal-Wallis test for comparison. RESULTS: A total of 378 patients who underwent TEA were identified. The mean reimbursement cost of the surgical encounter ($13,393 ± $8314) did not differ significantly based on patient factors. The mean reimbursement cost of the 89-day postoperative period ($4232 ± $2343) differed significantly when stratified by surgical indication (P < .0001) or by medical comorbidity (P < .0001). The indication of rheumatoid arthritis ($4864 ± $1136) and the comorbidity of chronic kidney disease ($5873 ± $1165) had the most expensive postoperative period. In addition, the total 90-day reimbursement cost ($16,982 ± $4132) differed significantly when stratified by surgical indication (P = .00083) or by medical comorbidity (P < .0001), with the indication of acute fracture ($18,870 ± $3971) and the comorbidity of chronic pulmonary disease ($19,194 ± $3829) showing the highest total 90-day cost. Inpatient costs related to readmissions represented 38% of the total reimbursement cost. The overall readmission rate was 5.0%, and the mean readmission cost was $16,296. CONCLUSION: TEA reimbursements are significantly influenced by surgical indications and medical comorbidities during the postoperative period and the total 90-day episode of care. As the United States transitions to delivering value-based health care, the need for surgeons and policy makers to understand treatment costs associated with different patient-level factors will expand.

Anterior Capsule Reconstruction in the Setting of PVNS.

BACKGROUND: Pigmented villonodular synovitis (PVNS) is a benign proliferative disease affecting tendon sheaths and synovial tissue. Pigmented villonodular synovitis in the foot and ankle has a high rate of recurrence, which can be destructive if incompletely removed. This case series analyzes functional outcomes after PVNS operative resection with an anterior ankle capsular reconstruction, using a novel technique. METHODS: Three patients with PVNS underwent surgery between 2010 and 2020. The operative technique involved a posterior, midline approach for PVNS resection of the affected ankle joint, followed by a standard anterior approach for capsular excision. Subsequent anterior capsular reconstruction was performed with a regenerative tissue matrix and a bioresorbable anchoring system. Preoperative and postoperative range of motion for the ankle and subtalar joints, visual analog scale (VAS) for pain, and return to daily activities was assessed along with appropriate radiographs and magnetic resonance imaging (MRI) imaging. RESULTS: All 3 surgeries had a mean follow-up period of 52.3 (range, 4-123) months and resulted in successful recovery as assessed by the VAS and self-reported activity. Preoperative ankle dorsiflexion and plantarflexion along with subtalar inversion and eversion range of motion were all normal. Postoperative ankle motion and subtalar motion were not statistically different. No complications or recurrence of PVNS was observed. CONCLUSION: Further investigation is warranted to better understand the clinical outcomes of this technique designed to successfully eliminate PVNS recurrence.

Accuracy of institutional orthopedic trauma databases: a retrospective chart review.

INTRODUCTION: Academic trauma institutions rely on fracture databases as research and quality control tools. Frequently, these databases are populated by trainees, but the completeness and accuracy of such databases has not yet been evaluated. The purpose of this study is to determine the capture rate of a resident-populated database in collecting extremity fractures and to determine the accuracy of assigned Orthopaedic Trauma Association (OTA) classifications. MATERIALS AND METHODS: A retrospective study was performed at a level 1 trauma center of all adult patients who underwent treatment for extremity fractures after an emergency department or inpatient consultation. A 20% random sample was taken from these entries and compared to a resident-populated fracture database designed to capture the same patients. For all matching records containing a resident-assigned OTA classification, relevant imaging was blindly reviewed by a trauma fellowship-trained orthopedic attending surgeon for fracture pattern classification. Resident OTA classifications were compared to this gold standard to determine overall accuracy rate. RESULTS: Three hundred eighteen (80%) out of 400 entries were captured by the resident-populated database. Two hundred thirty-one of these 318 entries contained an OTA classification. One hundred fifty-three (66%) of these 231 entries demonstrated concordance between resident and attending assigned OTA classifications. On subgroup analysis, 133 (70%) of the 190 lower extremity classifications were accurately identified as compared to just 20 (49%) of the 41 upper extremity classifications (p = 0.009). Seventy-nine (65%) of the 121 end segment fractures showed agreement versus 42 (67%) of the 63 diaphyseal injury patterns (p = 0.85). Accuracy of classification did not significantly vary by resident year of training (p = 0.142). CONCLUSION: Trainee generated databases at academic institutions may be subject to incomplete data entry and inaccurate fracture classifications. Quality control measures should be instituted to ensure accuracy in such databases if efforts are invested with the expectation of useful information.

Rates of readmission and reoperation after operative management of midshaft clavicle fractures in adolescents.

BACKGROUND: The national rates of readmission and reoperation after open reduction internal fixation (ORIF) of midshaft clavicle fractures in adolescents is unknown. AIM: To determine rates of and risk factors for readmission and reoperation after ORIF of midshaft clavicle fractures in adolescents. METHODS: This retrospective study utilized data from the Healthcare Cost and Utilization Project State Inpatient Database for California and Florida and included 11728 patients 10-18 years of age that underwent ORIF of midshaft clavicle fracture between 2005 and 2012. Readmissions within ninety days, reoperations within two years, and differences in patient demographic factors were determined through descriptive, univariate, and multivariate analyses. RESULTS: In total, 3.29% (n = 11) of patients were readmitted within 90 d to a hospital at an average of 18.91 ± 18 d after discharge, while 15.87% (n = 53) of patients underwent a reoperation within two years at an average of 209.53 ± 151 d since the index surgery. The most common reason for readmission was a postoperative infection (n < 10). Reasons for reoperation included implant removal (n = 49) at an average time of 202.39 ± 138 d after surgery, and revision ORIF (n < 10) with an average time of 297 ± 289 d after index surgery. The odds of reoperation were higher for females (P < 0.01) and outpatients (P < 0.01), while the odds of reoperation were lower for patients who underwent surgery in California (P = 0.02). CONCLUSION: There is a low rate of readmission and a high rate of reoperation after ORIF for midshaft clavicle fractures in adolescents. There are significant differences for reoperation based on patient sex, location, and hospital type.
