The Effect of First Metatarsal Shortening and Sagittal Displacement on Forefoot Pressure in Minimally Invasive Hallux Valgus Correction.

BACKGROUND: Minimally invasive (MIS) treatment of hallux valgus (HV) deformity is increasing in popularity. A 2-mm diameter burr is used to create a distal first metatarsal osteotomy prior to capital fragment translation and fixation. The metatarsal will shorten by the burr's diameter (2 mm). Plantar or dorsal capital fragment displacement may also cause load transference and possibly transfer metatarsalgia. The purpose of this study is to examine the effect of MIS HV on forefoot loading mechanics with respect to metatarsal shortening and sagittal plane displacement. METHODS: Four lower-limb cadaveric specimens were studied. A pedobarography pressure-sensing mat was used to record forefoot plantar pressure in a controlled weight-bearing stance position. Control and postosteotomy measurements were obtained with the capital fragment fixated in 3 possible positions: 0 mm, 5 mm dorsal, and 5 mm plantar displacement. Pedobarography data yielded pressure data within measurable graphical depictions. Raw mean contact pressure measurements were taken under the first and fourth metatarsal heads to establish medial and lateral forefoot loading pressure ratios. An a priori power analysis was performed based on previous peer-reviewed pedobarographic data, and our study was adequately powered. RESULTS: Around 40 measurements were recorded, and ratios of medial-to-lateral forefoot loading were constructed. Medial forefoot pressure control versus 0 mm displacement, and control versus dorsal displacement were not found to be statistically significant (p = 0.525, p = 0.55, respectively). Medial pressure significantly increased when comparing control versus plantar displacement (P = .006). Lateral pressure significantly increased with dorsal displacement of the osteotomy (P = .013). CONCLUSION: Our study found that MIS HV correction did not cause an increase in lateral forefoot pressure loading when sagittal plane displacements were controlled. Plantar displacement increased medial loading, and dorsal displacement increased lateral loading. It may be valuable for surgeons to consider metatarsal head position postosteotomy, as a decrease in medial loading and subsequent increase in lateral loading may lead to lateral forefoot pain and transfer metatarsalgia.

Open Ankle Fractures in Older Individuals: A Multi-center Study.

The purpose of this study is to identify demographics, etiology, comorbidities, treatment, complications, and outcomes for older patients with open ankle fractures. Patients ≥60 years old who sustained an open ankle fracture between January 1, 2004 - March 31, 2014 at 6 Level 1 trauma centers were retrospectively reviewed. Univariate analysis using Chi-squared or Student's T-test was performed to identify associations between preoperative variables and two postoperative outcomes of interest: amputation and 1-year mortality. Multivariate analysis was performed using stepwise logistical regression to identify independent predictors of postoperative amputation and 1-year mortality. Of the 162 total patients, the most common mechanism of injury was a ground-level fall (51.9%). The most common fracture types were bimalleolar fractures (52.5%) followed by trimalleolar fractures (26.5%), with 41.5% of the fractures classified as Gustilo Anderson Classification Type 2 and 38.6% classified as Type 3A. The average number of surgeries required per patient was 2.1. Complications included: 15.4% superficial infection rate, 9.9% deep infection rate, and 9.3% amputation rate. The 1-year mortality rate was 13.6% and the overall mortality rate was 25.9%. Male gender and fracture type were found to be independent predictors for amputation after surgery (P = 0.009, 0.005, respectively). Older age and having diabetes were independent predictors for 1-year mortality after surgery (P = 0.021, 0.005 respectively). Overall, open ankle fractures in older individuals were associated with high rates of amputation and mortality.

The surgical learning curve for percutaneous Zadek osteotomy for treatment of insertional achilles tendinopathy.

INTRODUCTION: The Zadek Osteotomy has been described as an effective technique for the treatment of insertional Achilles tendinopathy. Recently, this strategy has been modified using minimally invasive techniques. A learning curve has been observed in many minimally invasive procedures in foot and ankle surgery. This retrospective study first intended to evaluate if there is a learning curve associated with the percutaneous Zadek Osteotomy. Further, if a learning curve was observed, we planned to assess the data for associated changes in complications and postoperative outcomes. METHODS: A retrospective analysis of 98 patients who underwent percutaneous Zadek Osteotomy was performed. Patient charts were reviewed for operative times, complications, union rates, and Foot Function Index (FFI) and Visual Analogue Scale (VAS) scores. Analysis of variance was utilized to assess for differences between groups of cases. RESULTS: Patients included 61 females and 37 males. Mean age was 51.28 ± 11.12 (range 28-81) years. Mean follow-up time was 42.07 ± 12.99 (range 24-65) months. Significant increases in operative times were observed in cases 1-14 when compared to cases 15-98 (p < 0.001). Improvements in FFI and VAS scores were observed at final follow-up within each case group (p < 0.001); there were no differences detected in FFI or VAS scores between groups of cases. There was no difference detected in number of complications between intervals of cases. CONCLUSION: A learning curve was observed for the percutaneous Zadek Osteotomy, which was overcome around case 14. This learning curve was only observed in terms of procedure length. A surgeon's level of inexperience with the technique does not appear to affect functional outcomes, nonunion, or need for revision. LEVEL OF EVIDENCE IV: Data will not be deposited in a repository.

Body Mass Index, Sex, and Age Are Predictors of Discharge to a Post-acute Care Facility Following Total Ankle Arthroplasty.

BACKGROUND: The utilization of total ankle arthroplasty (TAA) continues to increase. Discharge to a post-acute care (PAC) facility can increase patient morbidity and postoperative costs. The purpose of this study is to investigate the effects of age and body mass index (BMI) on discharge to a PAC facility and hospital length of stay (LOS) following TAA. METHODS: A retrospective review of patients who underwent TAA from the National Surgical Quality Improvement Program (NSQIP) database was performed. Using overweight patients as the reference BMI group, sex- and age-adjusted log-binomial regression models were utilized to estimate risk ratios of BMI categories for being discharged to a PAC facility. A linear regression was utilized to estimate the effect of BMI category on hospital LOS. RESULTS: Obese patients had 1.36 times the risk of overweight patients (P = .040), and morbidly obese patients had 2 times risk of overweight patients (P = .001) of being discharged to a PAC facility after TAA. Men had 0.48 times the risk of women (P < .001). Compared with patients aged 18 to 44 years, patients aged ≥65 years had 4.13 times the risk (P = .012) of being discharged to a PAC facility after TAA. Relative to overweight patients, on average there was no difference in hospital LOS for underweight patients, but healthy weight patients stayed an additional 0.30 days (P=.003), obese patients stayed an additional 0.18 days (P = .011), and morbidly obese patients stayed an additional 0.33 days (P = .009). Men stayed 0.29 fewer hospital days than women (P < .001) on average. CONCLUSION: Women and patients who are obese or morbidly obese have a longer hospital LOS and an increased chance of being discharged to a PAC facility. Increasing age is also associated with an increased risk of being discharged to a PAC. These may be important factors when developing and discussing the postoperative plan with patients prior to TAA.

Percutaneous vs Open Zadek Osteotomy for Treatment of Insertional Achilles Tendinopathy and Haglund's Deformity: A Systematic Review.

Background: Percutaneous Zadek osteotomy (ZO) has emerged as a surgical treatment of insertional Achilles tendinopathy (IAT) over the last decade. Existing literature is limited regarding the comparison of this approach with the more established, open ZO technique. This systematic review aims to evaluate and compare the current data on open vs percutaneous ZO approaches to help set evidence-based guidelines. Methods: A systematic literature search was performed using the keywords (Zadek osteotomy) OR (Keck and Kelly osteotomy) OR (dorsal closing wedge calcaneal osteotomy) OR (Haglund Deformity) OR (Haglund Syndrome) OR (Insertional Achilles Tendinopathy) and MeSH terms Osteotomy, Calcaneus, Syndrome, Insertional, Achilles tendon, and Tendinopathy. Our search included the following databases: PubMed, Embase, and the Cochrane Library. The PRISMA protocol and the Cochrane Handbook guidelines were followed. All studies included were published from 2009 to 2024 and included the use of open or percutaneous approaches of ZO for the treatment of IAT with at least a 12-month follow-up. The MINORS score criteria were used to evaluate the strength and quality of studies. Results: A total of 17 studies were reviewed, including 611 subjects and 625 ZO procedures. Of these procedures, 81 (11%) subjects had a percutaneous and 544 (89%) subjects had an open ZO. The mean follow-up time was 16.1 months for patients treated with percutaneous ZO and 36.1 months for patients treated with open ZO. Both open and percutaneous studies included in this review showed postoperative improvements in AOFAS, FFI, VISA-A, and VAS scores in patients with IAT. The reported complication rate was 5.8% among patients treated with percutaneous ZO and 10.2% among patients treated with open ZO. Conclusion: Percutaneous ZO is an emerging approach with substantially fewer documented cases compared with the open ZO. Both percutaneous and open ZO appear to be relatively effective treatments for insertional Achilles tendinopathy with Haglund's deformity. The lower complication rates reported for percutaneous ZO is encouraging. Further investigation with more subjects undergoing percutaneous ZO is clearly needed.

Minimally invasive Dorsal cheilectomy and Hallux metatarsophalangeal joint arthroscopy for the treatment of Hallux Rigidus.

BACKGROUND: Minimally invasive dorsal cheilectomy (MIDC) has become a popular alternative to an open approach for treating Hallux Rigidus (HR). To reduce some of the complications related to the MIDC approach, a first metatarsophalangeal (MTP) joint arthroscopy can be performed in addition to address the intra-articular pathology associated with Hallux Rigidus. This study aims to examine the effectiveness of MIDC with first MTP arthroscopy in patients with HR with a minimum 1-year follow-up. METHODS: This was a multicenter retrospective review for adult patients with Coughlin and Shurnass Grade 0-3 who were treated with MIDC and first MTP arthroscopy between 3/1/2020 and 8/1/2022, with at least one year of follow-up data. Demographic information, first MTP range of motion (ROM), visual analog scale (VAS), Manchester-Oxford Foot Questionnaire (MOXFQ), and EQ-5D-5 L scores were collected. Continuous data was expressed as a mean and standard deviation, categorical data was expressed as a percentage. Wilcoxon Rank Sum test was used to compare continuous variables. All P < 0.05 was considered significant. RESULTS: A total of 31 patients were included in the study. Average follow-up time was 16.5 months (range: 12 to 26.2). There was 1 (3.2%) undersurface EHL tendon tear, 2 (6.5%) conversions to an MTP fusion, and 1 (3.2%) revision cheilectomy and capsular release for MTP joint contracture. There was a significant improvement in patient's ROM in dorsiflexion (50 vs 89.6 degrees, P = 0.002), postoperative VAS pain scores (6.4 vs 2.1, P < 0.001), MOXFQ pain scores (58.1 vs 30.7, P = 0.001), MOXFQ Walking/Standing scores (56.6 vs 20.6, P = 0.001), MOXFQ Social Interaction scores (47.3 vs 19.36, P = 0.002), and MOXFQ Index scores (54.7 vs 22.4, P < 0.001). CONCLUSION: We found that MIDC with first MTP arthroscopy was effective at improving patient-reported outcomes at one year with low complication and revision rates. These results suggest that MIDC with first MTP arthroscopy is an effective treatment for early-stage HR. LEVEL OF EVIDENCE: IV.

Total Joint Arthroplasty Outcomes in Eligible Patients Versus Patients Who Failed to Meet at Least 1 Eligibility Criterion: A Single-Center Retrospective Analysis.

BACKGROUND: This study looks to investigate how not meeting eligibility criteria affects postoperative outcomes following total joint arthroplasty surgery. METHODS: A retrospective review was conducted of total joint arthroplasty patients at a single academic institution. Demographics, laboratory values, and complications were recorded. Continuous and categorical variables were compared using the Student's T-test and the Chi-Square test, respectively. Multivariable analysis was used to control for confounding variables. RESULTS: Our study included 915 total hip and 1,579 total knee arthroplasty patients. For total hip and total knee arthroplasty, there were no significant differences in complications (P = .11 and .87), readmissions (P = .83 and .2), or revision surgeries (P = .3 and 1) when comparing those who met all criteria to those who did not. Total hip arthroplasty patients who did not meet two criteria had 16.1 higher odds (P = .02) of suffering a complication. There were no differences in complications (P = .34 and .41), readmissions (P = 1 and .55), or revision surgeries (P = 1 and .36) between ineligible patients treated by total joint arthroplasty surgeons and those who were not. Multivariable analysis demonstrated no eligibility factors were associated with outcomes for both total hip and knee arthroplasty. CONCLUSIONS: There was no significant difference in outcomes between those who met all eligibility criteria and those who did not. Not meeting two criteria conferred significantly higher odds of suffering a complication for total hip arthroplasty patients. Total joint arthroplasty surgeons had similar outcomes to non-total joint surgeons, although their patient population was more complex. LEVEL OF EVIDENCE: III.

A Retrospective Comparative Analysis on the Effect of Tranexamic Acid to Reduce Perioperative Blood Loss in Patients Undergoing Cervical Spine Surgery.

STUDY DESIGN: Retrospective Cohort Study. OBJECTIVE: The purpose of this study is to assess the impact of intravenous TXA on blood loss outcomes in anterior, posterior, and combined approaches for elective cervical spine surgery. SUMMARY OF BACKGROUND DATA: Tranexamic acid (TXA) has been shown to reduce blood loss in a variety of operations, such as lumbar spine surgery. However, limited studies have evaluated the efficacy of TXA in cervical spine surgery. METHODS: We performed a retrospective review of a single surgeon's elective cervical spine operations between September 2011 and March 2017. Patients were divided into 3 groups: anterior approach, posterior approach, or combined approach. Patients were then further subdivided into TXA versus control groups based on whether they received TXA treatment. We performed multiple linear regressions to assess the relationship between the use of TXA and other dependent variables (number of vertebral levels treated, need for a vertebral corpectomy) on total perioperative blood loss, intraoperative estimated blood loss, postoperative drain output, total operative time, postoperative change in hemoglobin, and occurrence of transfusion and/or postoperative deep venous thrombus (DVT). RESULTS: We found that the use of TXA statistically significantly reduced total perioperative blood loss ( P =0.04) and postoperative drain output ( P =0.004) in posterior surgical approach cervical spine surgery but did not statistically significantly impact any blood loss variables in anterior or combined surgical approaches to elective cervical spine surgery. The use of TXA was a significant predictor for a decrease in intraoperative ( P =0.02) and postoperative ( P <0.01) blood loss. CONCLUSIONS: This study found that TXA statistically significantly decreased total blood loss and postoperative drain output when controlling for multiple confounding factors. LEVEL OF EVIDENCE: Level III.

Analysis of Nonweightbearing MRI Fat Pad Thickness Under Central Metatarsals in Patients With and Without Metatarsalgia.

BACKGROUND: Metatarsalgia is a common diagnosis for patients with forefoot pain. Many have proposed metatarsal fat pad atrophy is a cause of metatarsalgia and therefore have suggested fat grafting instead of distal metatarsal osteotomies to treat metatarsalgia. For fat grafting to be a viable treatment, fat pad atrophy should correlate with metatarsalgia. This study looked to determine the relationship between metatarsal fat pad thickness and metatarsalgia and the correlation between metatarsal fat pad thickness and patient-reported outcomes. METHODS: We conducted a retrospective review of patients with metatarsalgia and those with foot or ankle osteoarthritis who had a nonweightbearing MRI performed between February 1, 2021, and March 1, 2023. Data collected included demographics, PROMIS scores, metatarsal fat pad thickness in the second and third rays of the affected foot, and thinnest area on coronal section, measured on MRI. Student t test was used to compare continuous variables, whereas the χ2 test was used to compare categorical variables. Multivariable linear regression models were used to control for potential confounding factors. RESULTS: A total of 112 patients were included in this study. Patients with metatarsalgia were significantly more likely to have a lower body mass index (29.3 vs 32.0, P = .03) than patients with osteoarthritis, but this finding was not present when controlling for confounding variables. We found no significant difference in fat pad thickness between patients with metatarsalgia vs patients with foot or ankle osteoarthritis (P = .43). We found no correlation between metatarsal fat pad thickness and pain interference (P = .59), physical function (P = .64), or mobility (P = .94) PROMIS scores. CONCLUSION: In this retrospective comparative study of a relatively small cohort we found no significant difference in metatarsal fat pad thickness for patients with metatarsalgia vs patients with foot and ankle osteoarthritis based on nonweightbearing MRI, and no association between metatarsal fat pad thickness and patient-reported outcomes. LEVEL OF EVIDENCE: Level III, case control study.

Retrospective Review of Complications and Revision Rates Between Isolated Talonavicular vs Talonavicular and Subtalar (Double) Arthrodesis vs Triple Arthrodesis.

Background: Hindfoot fusion procedures are common for the treatment of end-stage arthritis or deformity. Surgical treatments for these conditions include talonavicular joint (single) arthrodesis, talonavicular and subtalar (double) arthrodesis, or talonavicular, subtalar, and calcaneocuboid (triple) arthrodesis. This study evaluated the complication rate, revision surgery rate, and hardware removal rate for those treated with either single, double, or triple arthrodesis. Methods: A retrospective review was conducted for patients who underwent single (Current Procedural Terminology [CPT] code 28740), double (CPT 28725 and 28740), or triple (CPT 28715) arthrodesis to treat hindfoot arthritis/deformity (International Classification of Diseases, Ninth Revision [ICD-9] code: 734, International Classification of Diseases, Tenth Revision [ICD-10] codes: M76821, M76822, and M76829) from 2005 to 2022 using the South Carolina Revenue and Fiscal Affairs databank. Data collected included demographics, comorbidities, procedure data, and postoperative outcomes within 1 year of principal surgery. Student t test, chi-squared test, and multivariable logistic regression analysis were utilized during data analysis. Results: A total of 433 patients were identified, with 248 undergoing single arthrodesis, 67 undergoing double arthrodesis, and 118 undergoing triple arthrodesis. There was no significant difference between single, double, and triple arthrodesis in the rate of complications, hardware removals, revision surgeries, or 30-day readmission when controlling for confounding variables. However, a decrease in Charlson Comorbidity Index (CCI) was found to be predictive of an increase in the revision surgery rate (OR = 0.46, 95% CI 0.22-0.85, P = .02). Conclusion: We found no difference in the rate of complications, hardware removals, or revision surgeries in those undergoing single, double, or triple arthrodesis. Surprisingly we found that a lower Charlson Comorbidity Index, indicating a healthier patient had a significant relationship with a higher rate of revision surgery. Further study including radiographic indications for surgery or the impact of overall health status on revision surgery rates may further elucidate the other components of this relationship. Level of Evidence: Level III, cohort study.

Comparison of the Acute Postoperative Complications Between Isolated Talonavicular Versus Talonavicular and Subtalar (Double) Arthrodesis in Flatfoot Deformity.

BACKGROUND: Both isolated talonavicular arthrodesis and talonavicular and subtalar (such as double) arthrodesis can be effective treatments for adult-acquired flatfoot deformity (AAFD) with good success rates, but double arthrodesis has become more commonly performed in recent years. The purpose of this study is to evaluate whether isolated talonavicular versus talonavicular and subtalar arthrodesis led to significantly different 30-day postoperative complication rates in patients with AAFD. METHODS: We performed a retrospective review to identify a large cohort of adult patients with the diagnosis of AAFD or posterior tibial tendon deformity (PTTD) who underwent isolated talonavicular or talonavicular and subtalar arthrodesis between 2006 and 2020 from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). To investigate whether there was a difference in complication rate between the 2 surgical cohorts, we estimated logistic regression models and log-binomial models on each of the outcomes while also adjusting for sex and age. RESULTS: We found that there was no significant difference in the rate of major complications (P = .567) or readmissions (P = .567) between patients who underwent isolated talonavicular versus talonavicular and subtalar arthrodesis for AAFD. However, there was a significantly higher rate of minor complications in patients who underwent isolated talonavicular arthrodesis when compared with patients who underwent talonavicular and subtalar arthrodesis (P = .009). CONCLUSION: This study found that there was no increased risk of 30-day postoperative complications or readmissions with talonavicular and subtalar arthrodesis when compared with isolated talonavicular arthrodesis for AAFD. In addition, there was no increased risk of major complications for talonavicular and subtalar arthrodesis when compared with isolated talonavicular arthrodesis, and isolated talonavicular arthrodesis actually carried a higher risk of minor complications for this surgical cohort. This may provide valuable information for surgeons considering surgical treatment for a particular case of AAFD. LEVEL OF EVIDENCE: Level III.

Evaluating ChatGPT Performance on the Orthopaedic In-Training Examination.

Background: Artificial intelligence (AI) holds potential in improving medical education and healthcare delivery. ChatGPT is a state-of-the-art natural language processing AI model which has shown impressive capabilities, scoring in the top percentiles on numerous standardized examinations, including the Uniform Bar Exam and Scholastic Aptitude Test. The goal of this study was to evaluate ChatGPT performance on the Orthopaedic In-Training Examination (OITE), an assessment of medical knowledge for orthopedic residents. Methods: OITE 2020, 2021, and 2022 questions without images were inputted into ChatGPT version 3.5 and version 4 (GPT-4) with zero prompting. The performance of ChatGPT was evaluated as a percentage of correct responses and compared with the national average of orthopedic surgery residents at each postgraduate year (PGY) level. ChatGPT was asked to provide a source for its answer, which was categorized as being a journal article, book, or website, and if the source could be verified. Impact factor for the journal cited was also recorded. Results: ChatGPT answered 196 of 360 answers correctly (54.3%), corresponding to a PGY-1 level. ChatGPT cited a verifiable source in 47.2% of questions, with an average median journal impact factor of 5.4. GPT-4 answered 265 of 360 questions correctly (73.6%), corresponding to the average performance of a PGY-5 and exceeding the corresponding passing score for the American Board of Orthopaedic Surgery Part I Examination of 67%. GPT-4 cited a verifiable source in 87.9% of questions, with an average median journal impact factor of 5.2. Conclusions: ChatGPT performed above the average PGY-1 level and GPT-4 performed better than the average PGY-5 level, showing major improvement. Further investigation is needed to determine how successive versions of ChatGPT would perform and how to optimize this technology to improve medical education. Clinical Relevance: AI has the potential to aid in medical education and healthcare delivery.

Outcomes and Complications After Bone Marrow Aspirate Harvest From the Calcaneus.

Background: Bone marrow aspirate (BMA) is used with the putative goal of enhancing healing of injured tissue. The most common sites to harvest BMA are the iliac crest, the tibia, and the calcaneus. Investigators have found that the tibia and calcaneus have fewer progenitor cells than the iliac crest. This retrospective review evaluates the efficacy and safety profile of harvesting BMA from the calcaneus bone. We hypothesized that harvesting BMA from the calcaneus will have high efficacy and safety profile with low complication rates. Methods: A retrospective chart review of patients undergoing bone marrow aspiration from the calcaneus bone from January 2019 to October 2022 was performed. The main data points evaluated were patient satisfaction and pain level, follow-up times, quantity of BMA harvested, fusion rates, and complications including nerve damage, infections, and nonunions. Results: There were 45 (34 female and 11 male) patients who underwent 45 procedures. The average age, BMI, and amount of BMA were 45.1 years (range 23-79), 33.1 (range 19.2-61.3), and 10.3 mL (range 2-40), respectively. There was no pain reported at the final follow-up in 32 patients (71.1%), and there was minimal to no pain in the area of surgery in the remaining 13 patients (28.9%). The 10 cases of fusion successfully healed with combined use of allograft and BMA. The average follow-up time was 12.3 months (range 2.4-33.7). There were no infections, wound complications, or nerve injuries. Conclusion: Harvesting BMA from the calcaneus bone is a safe procedure. In this heterogenous series where BMA augmented other surgical strategies, patients had little to no pain and there were no cases of wound complication or iatrogenic neuropraxia after undergoing bone marrow harvest from the calcaneus. Level of Evidence: Level IV, case series.

Effect of Supplemental Regional Anesthesia on the Complication and Readmission Rate of Patients After Elective Foot and Ankle Surgery.

BACKGROUND: The purpose of this study is to define the effect of facility type (inpatient vs outpatient) for the use of supplemental regional anesthesia (SRA), and SRA's effect on complications, readmissions, operation time, and length of hospital stay after elective foot and ankle surgery. METHODS: We performed a retrospective review to identify a large cohort of adult patients who underwent elective foot and ankle surgery between 2006 and 2020 from the American College of Surgeons National Surgical Quality Improvement Program database. We fit log-binomial generalized linear models to estimate risk ratios for general anesthesia (GA) with SRA versus GA alone, and linear regression models to estimate the effect of GA with SRA on the average total hospital length of stay (in days) and operation time (in minutes); we also performed inverse propensity scores. RESULTS: We found that there is no statistical difference in the rate of readmissions (P = .081) between patients under GA alone versus GA with SRA. In the propensity score analysis, patients who underwent midfoot/forefoot surgery had 3.85 times the risk of complications under GA with SRA compared with GA alone (P = .045). Also, patients who received GA with SRA had a longer unadjusted operative duration (102.22 minutes) when compared with patients who received GA alone (93.84 minutes) (P < .001). However, patients who received GA alone had a longer unadjusted hospital length of stay (0.88 days) when compared with patients who received GA with SRA (0.70 days) (P = .006). CONCLUSION: This study found that, when compared with GA alone, GA with SRA leads to a statistically significant increased operative time but a shorter hospital stay without significantly increasing readmissions and only increasing the risk of complications for midfoot/forefoot surgery within 30 days postoperatively for elective foot and ankle surgery. LEVEL OF EVIDENCE: Level III.

Opioid Usage After Hallux Valgus Correction Surgery.

BACKGROUND: Given the lack of objective data on opioid use and the difficulty of addressing a patient's postoperative pain, we sought to quantify patient's narcotic use after hallux valgus surgery. The purpose of our study was to determine the average quantity and type of postoperative opioids consumed after hallux valgus surgery and to assess potential predictive factors for increased opioid consumption. METHODS: At the preoperative visit, patients were consented and completed a demographical questionnaire. Data were collected from the operative record, 2, 6, and 12-week postoperative visits. Type and number of pills prescribed were recorded as well as number of pills consumed at each postoperative visit. A logistic regression was performed to determine the average quantity consumed postoperatively and any statistically significant correlations. RESULTS: The average number of opioid pills collectively consumed at the 2-week and 12-week postoperative visit was 20 and 23, respectively. At the 2-week postoperative visit, only patient body mass index (BMI) showed a correlation with increased opioid use. CONCLUSION: Patients consumed an average of 23 of 40 (57.5%) narcotic pain pills prescribed after hallux valgus reconstruction surgery through the 12-week postoperative period. Owing to the opioid epidemic and potential for narcotic diversion, surgeons should counsel their patients on proper nonopioid postoperative pain management. LEVEL OF EVIDENCE: II Therapeutic.

A cost analysis of ankle fractures treated by orthopedic surgeons with or without foot and ankle fellowship training at ambulatory surgery centers and hospitals.

Introduction: Ankle fractures are commonly treated by orthopedic surgeons. Fellowship versus non-fellowship training often adds a different perspective, use of specialty-specific implants, comfort with outpatient procedures, and may contribute to cost differences between surgeons. To assess the impact of fellowship training on the value of care provided, the difference in cost of ankle fracture open reduction internal fixation procedures between foot and ankle trained orthopedic surgeons and non-foot and ankle trained orthopedic surgeons over the past 10 years was retrospectively evaluated. We additionally evaluated the cost differences of ankle fracture open reduction internal fixations between hospitals, hospital-owned ambulatory surgery centers, and physician-owned ambulatory surgery centers. The study also assessed the costs effects of inpatient versus outpatient procedures and ankle open reduction internal fixation procedure volume of the surgeon observed within the timeframe of the study. Methods: Patient data was collected from electronic medical records and billing documents for patients who underwent an ankle open reduction internal fixation procedure performed by an orthopedic surgeon in our hospital system and local hospital-owned ambulatory surgery centers between the years 2010 and 2020. Data were also collected from a physician-owned ambulatory surgery center for patients who underwent an ankle open reduction internal fixation procedure performed by an orthopedic surgeon between the years 2015 and 2020. Statistical analyses were performed to observe potential cost differences among all variables. Results: Procedures performed by fellowship-trained orthopedic surgeons were significantly less costly than those performed by non-foot and ankle trained orthopedic surgeons when performed at ambulatory surgery centers but not at hospitals. Procedures performed at ambulatory surgery centers were found to be significantly less costly than those performed at hospitals. In addition, it was noted that procedures performed at hospital-owned ambulatory surgery centers were less costly than physician-owned ambulatory surgery centers. It was also found that procedure cost decreased with an increase in surgeon volume. Conclusion: An ankle fracture open reduction internal fixation performed by a foot and ankle trained orthopedic surgeon in a hospital-owned ambulatory surgery center is the lowest cost option available, and an increase in volume of open reduction internal fixations is associated with a further decrease in cost when within our hospital system between the years 2010 and 2020.
