Introduction/Purpose:
The most frequent cause of traumatic foot and ankle fractures is a fall to the ground. Alcohol consumption, especially in excess, has the ...potential to impart a significant fall risk on patients by reducing postural control resulting in imbalance. However, the relationship between the consumption of alcohol and the risk of traumatic foot and ankle fracture is poorly characterized. The purpose of this study was to report national estimates, injury mechanisms, and demographic characteristics of patients presenting to U.S. emergency departments (EDs) with traumatic foot and ankle fractures associated with alcohol consumption.
Methods:
This cross-sectional, retrospective epidemiological study analyzes case narratives in the National Electronic Injury Surveillance System (NEISS) database to examine national estimates of traumatic foot and ankle fractures associated with alcohol consumption presenting to U.S. emergency departments between 2000 and 2017, sampling in two-year intervals. Data from the Organisation for Economic Co-operation and Development (OECD) on the “Value for Total U.S. Adult Alcohol Consumption in Liters/Capita” was used in a simple regression model to demonstrate how increased alcohol consumption in the United States has predicted changes in the national number of alcohol-associated foot and ankle fractures over time.
Results:
Nationally, alcohol-associated foot and ankle fractures increased significantly between the 2000-2001 (N=2,878; C.I. 1,869-3,887) and 2016-2017 (N=8,778; C.I. 6,751-10,806) periods (p<0.001). Simple regression (R2 = 0.87; p<0.001) demonstrated that in the U.S., a one-tenth increase in the total liters of alcohol consumed per capita predicted an additional 606 alcohol-associated foot and ankle fractures presenting to U.S. EDs. About two-thirds of patients suffered ankle fractures (65.6%; C.I. 61.1%-70.1%). Fractures were commonly sustained by male patients (58.4%; C.I. 53.9%-62.9%) at home (46.5%; C.I. 40.9%- 52.2%); roughly one-third of patients required admission to the hospital (29.7%; C.I. 24.5%-34.9%). The most common injury mechanisms for alcohol-associated foot and ankle fractures were falls to the ground from standing height (33.0%; C.I. 28.8%- 37.2%), and falls down stairs or steps (31.0%; C.I. 26.1%-35.9%).
Conclusion:
Falls to the ground mechanistically link alcohol consumption to traumatic fractures of the foot and ankle. These new findings highlight how the negative societal impacts of alcohol – and potentially other substances – may be overlooked. As a result, this information should serve as an impetus to direct national attention towards awareness and preventative measures. Furthermore, our findings may help clinicians identify, educate, and counsel patients with certain demographic risk factors for alcohol-associated foot and ankle fractures.

Patient Care
Introduction/Purpose:
Initial impressions between physician and patient typically occur through the medium of attire and potentially gender and can significantly impact the ...comfort and trust of patients in the clinical setting. The influence that foot and ankle orthopaedic physicians have on their patient’s footwear choices is of particular importance because it potentially affects clinical outcomes. Unlike other specialties where physician appearance or gender serves as a basis for mere initial perception, the nature of foot & ankle orthopedics allows for direct influence on a component of their care. The purpose of this study was to examine whether orthopedic physicians may serve as role models for healthy behavior and to elucidate the influence of patient perception on their orthopedic-related decision making.
Methods:
In this prospective, cross-sectional study, individuals =18 years of age that had the ability to make their own footwear decisions were invited to participate. Study subjects completed a 22-question survey following their office visit with one of four foot and ankle surgeons (2 female, 2 male). Quantitative assessment included: demographic data, the level of perception and attention given to their physician’s shoe choices, and various factors that affect decision making process when purchasing orthopedic-related footwear. Chi-square analysis was used to evaluate the categorical variables.
Results:
A total of 250 patients completed the study, with a normal distribution of ages between 18-81. 62% (n=154) had seen their physician multiple times and the remaining were new patients. Female patients preferred using recommendations from same- sex surgeons (41%) much more than males (6%). However, given the option of combining male/female opinions, 45% of females chose that option whereas 72% of males preferred combing male/female physician opinions when deciding on footwear. A sizable minority of patients noticed the type of shoe their physician was wearing that day, 32% (n=81). 52% (n=130) agreed that a surgeon’s own shoe choices should reflect the desirable attributes of a shoe. Patients ranked the shoe feel (51%) and their doctor’s recommendations (28%) as the top factors when deciding shoe-wear.
Conclusion:
Our study indicates that a significant portion of patients are mindful about and do consider their physician’s gender as well as physical appearance including shoe choices. While this influence was greater for females, patient footwear choices are affected across most demographics. The impact of patients’ awareness on medical action indicates that perception of care may hold significant value. Identifying the factors that influence orthopaedic decision-making can aid in accurately targeting patient education, enhancing physician-patient interactions, and improving clinical outcomes.

Introduction/Purpose:
Hyperpronation of the 1st metatarsal in hallux valgus (HV) is poorly understood by conventional weightbearing radiography. We aimed to ...evaluate this parameter using weightbearing computed tomography (WBCT) and understand its association with other standard measurements.
Methods:
Retrospective evaluation of WBCT and weightbearing radiographs (WBXR) was performed for 20 patients with hallux valgus (HV) feet and 20 controls with no such deformity. Axial CT images of both groups were compared for 1st metatarsal pronation angle (α angle) and tibial sesamoid subluxation (TSS) grades. The hallux valgus angle (HVA), first-second intermetatarsal angle (IMA), 1st metatarsal-medial cuneiform angle (MMCA), Meary’s angle, and calcaneal pitch (CP) angle of the study and control groups were compared on both WBXR and the corresponding 2D images of WBCT. All the measurements were independently studied by a dedicated musculoskeletal radiology fellow.
Results:
HV group demonstrated significantly higher values for TSS grade (p < 0.001) but not for α angle (p = 0.19) compared to controls. Pearson’s correlations of the α angle, in the HV group, revealed no significant linear relationship with TSS grades, IMA and MMCA, and only a moderate positive correlation with HVA as per WBXR (r = 0.38, p = 0.014) but not by WBCT (p = 0.084). Also, α angle performed within the range of a chance (AUC 0.64, 95% CI: 0.49 to 0.66) when measured by receiver operating characteristic (ROC) curves.
Conclusion:
The α angle - a measure of abnormal hyperpronation of the 1st metatarsal - is an independent factor that may co- exist with other parameters in HV, but in isolation has limited diagnostic utility. ‘Abnormal’ α angles may even be observed in individuals without HV deformity. An increase in the HVA, IMA, MMCA or TSS grade is not necessarily associated with a similar increase in the α angle and hence, the severity of HV deformity may not be judged on this parameter alone. The WBCT is a reliable method to assess hyperpronation and guide physicians during surgical management.

Introduction/Purpose:
There is no standard guideline for prescription opioids for postoperative pain management following outpatient foot and ankle surgery. ...Multiple previous studies demonstrated that opioids were overprescribed. The purpose of this study was to prospectively investigate opioid consumption using multimodal analgesia regimen after two of the most common forefoot surgeries: isolated hallux valgus correction or 1st metatarsophalangeal (MTP) joint arthrodesis.
Methods:
We prospectively investigated opioid prescription and consumption of total 21 patients who underwent isolated hallux valgus correction with distal soft tissue procedure and proximal first metatarsal crescentic osteotomy or 1st MTP joint arthrodesis. Postoperative pain was managed using multimodal analgesia including oxycodone, ibuprofen, acetaminophen, and regional ankle block. Patients were instructed to take 5mg of oxycodone every 4 hours as needed, and 600 mg of ibuprofen as well as 1,000 mg of acetaminophen every 8 hours regularly. The number of pills patients consumed for oxycodone was recorded at postoperative follow-up at 1-week, 2-week, 4-week, 8-week, and 12-week. Subgroup analysis was performed to evaluate opioid consumption according to the prescription type: Only oxycodone was prescribed in group A while oxycodone as well as prescription strength ibuprofen and acetaminophen were prescribed in group B. Another subgroup analysis in opioid consumption was performed based on the quantity of opioid prescription and procedure type.
Results:
The overall mean opioid consumption in 12 weeks of the postoperative period was 16.2 pills per patient with an average of 37.3 pills prescribed. Lower opioid consumption was noted in group B when prescription ibuprofen and acetaminophen were prescribed compared to group A when patients took over-the-counter (OTC) ibuprofen and acetaminophen: 9.0 pills vs 24.1 pills, respectively (P = 0.036). There was a trend showing higher opioid consumption in patients prescribed greater than 30 pills of oxycodone compared to less than or equal to 30 pills: 22.0 pills vs 9.8 pills, respectively (P = 0.099). No significant difference was found in opioid consumption according to the procedure type: 15.8 pills in hallux valgus correction vs 16.5 pills in 1st MTP joint arthrodesis (P = 0.750).
Conclusion:
This study showed that on the average, patients took 16.2 pills out of 37.3 pills of the prescribed oxycodone after isolated hallux valgus correction or 1st MTP joint arthrodesis using our multimodal analgesia regimen. Patients who were prescribed prescription strength ibuprofen and acetaminophen consumed opioid significantly less than those who took the OTC strength. No significant difference was noted in opioid consumption between isolated hallux valgus correction and 1st MTP joint arthrodesis.

Introduction/Purpose:
Polyvinyl Alcohol Hydrogel (PAH) hemiarthroplasty has gained popularity in the operative management of symptomatic hallux rigidus since its ...introduction to the US in July 2016. Despite encouraging initial results, any implant has the potential for complications that may not become apparent until it is in widespread use. Also, the series of publications supporting the effectiveness of PAH have come from a limited group of institutions and surgeons which creates an opportunity for observational bias. Other complications or unsatisfactory outcomes may be under-reported, such as those experienced in community centers due to the challenges in publishing lower volume work. In order to look at a broader range of potential complications, we reviewed the United States Food and Drug Administration’s (FDA) database and compared with published literature.
Methods:
The Manufacturer and User Facility Device Experience (MAUDE) database of the US Food and Drug Administration (FDA) was retrospectively reviewed between July 2016 and October 2019 using the assigned product code: PNW for the PAH implant. All the reported adverse events, implant-related complications, and secondary procedures were analyzed.
Results:
A total of 49 events have been reported to this voluntary database over the past 3 years while over 22,000 Cartiva devices have been implanted. Implant subsidence was the most common with 16 reported instances. Fragmentation of the device was observed in nine and four reports were related to infection in which two were deep infections needing antibiotic spacers.
Bone erosion managed by grafting was documented in three reports and foreign body reaction was noted in one. Persistent pain and swelling were common presentations. Thirty-five of 49 reported events required additional operative procedures performed at a mean interval of 4.75 months following the index procedure while four more were awaiting further surgery. Conversion to fusion was the most common procedure, featured in 10 reports.
Conclusion::
The analysis of the MAUDE database disclosed certain device-related dysfunctions that have been under-reported in the published literature. Also, complications such as fragmentation, bone erosion and foreign body reaction have not been previously described. Awareness of these details will assist in decision-making and quality control. Due to the voluntary nature of reporting, the true incidence of each complication is unknown with the above data representing a baseline. Nonetheless, the MAUDE database serves as an illuminating source of information which would further be strengthened by a more robust and mandatory reporting of device-related complications.

Introduction/Purpose:
The majority of hallux valgus corrections are performed via a uniplanar metatarsal osteotomy approach in which the metatarsal is cut and ...shifted over in the transverse plane. This approach has demonstrated high long-term recurrence rates. Recent research demonstrates that 87% of hallux valgus deformities are three-dimensional with abnormal frontal-plane rotation of the metatarsal, which cannot be fully addressed with a uniplanar metatarsal osteotomy. While correction at the 1st tarsometatarsal (TMT) joint may provide the optimal surgical approach for 3D anatomic restoration at the apex of the deformity, 1st TMT fusion has historically involved an extended period of non-weightbearing. This study evaluates the clinical, radiographic, and patient-reported outcomes in patients undergoing instrumented triplanar 1st TMT arthrodesis (TTA) with a biplanar plating system and protected near-immediate weightbearing.
Methods:
This is a prospective multicenter study that will continue for 60 months post-operatively. Patients between 14-58 years old with symptomatic hallux valgus (intermetatarsal and hallux valgus angles between 10.0-22.0° and 16.0-40.0°, respectively) and no prior hallux valgus surgery on the operative foot are eligible for this study. Patients are treated with an TTA procedure using a biplanar plating system with protected near-immediate weightbearing. Outcomes (radiographic, range of motion (ROM), pain measured by visual analog scale (VAS), Manchester-Oxford Foot Questionnaire (MOxFQ), return to weightbearing and activities) are evaluated post-operatively. Two independent musculoskeletal radiologists reviewed radiographic data. These interim results are limited to patients completing at least 6 weeks of follow-up.
Results:
At time of data cut-off, 74 patients had undergone TTA with at least 6 weeks follow-up. The majority of patients were women (95%) with mean age 41.7 years. The mean (95% confidence interval) time to protected weightbearing in CAM boot was 8.0 (6.4, 9.7) days, return to work was 19.0 (13.6, 24.4) days, and return to full work was 31.5 (22.7, 40.2) days. There was a significant change in radiographic measures pre vs. post procedure and changes were maintained over time (Table). VAS pain score decreased 4 and 6 months post-procedure by 3.9 (3.2, 4.6) and 4.2 (3.5, 5.0), respectively. The mean MOxFQ Index Score pre-procedure was 53.3 (49.5, 57.1) and at month 6 had decreased to 18.6 (12.9, 24.2).
Conclusion:
These interim findings support that TTA with biplanar plating is successful in correcting the 3D hallux valgus deformity with early return to weightbearing and demonstrated favorable clinical and patient-reported outcomes. Patients were able to return to full, unrestricted work and activities within just a few months and had meaningful pain reduction after surgery. Patients will continue to be followed for up to 60 months. Clinical/radiographic healing at 12 months and recurrence rates at 24 months, as well as complications and patient satisfaction, will be evaluated.
Background: Substitutes for bone graft have been advocated to avoid the potential morbidity associated with harvest of autogenous iliac crest graft. However, no current commercially available graft ...equals autogenous bone's osteoinductive and osteoconductive qualities. We reviewed our patients' morbidity after harvest of anterior iliac crest bone grafts for procedures involving the foot and ankle. Methods: A computerized analysis of patient records was undertaken to identify all patients who had a harvest of unicortical iliac crest bone graft during a 12-year period. Patients were contacted either by telephone or by mailed questionnaire, inquiring about the postoperative morbidity of the procedure. Medical records were reviewed for any related complications. Results: Of the 169 patients identified, 134 could be contacted. Follow-up ranged from 1 to 13 years. Not all patients answered every question. At latest follow up, 120 (90%)-patients reported no pain at the bone graft site. Eleven patients complained of persistent residual numbness lateral to the harvest site on the pelvis. Of these 120 patients, 32 (27%) reported that pain at the graft site was greater than the pain at the operative site during the initial postoperative period. No patients had extra hospital days as a result of the bone graft harvest. No deep infections occurred, although 12 (6.7%) of 180 patients had a postoperative hematoma or seroma. Overall, 116 (90%) of 129 patients were satisfied or very satisfied with their bone graft harvest. Conclusions: Harvesting of autogenous iliac crest bone graft provides the optimal bone graft material, yields minimal morbidity, and is an acceptable choice in supplementing surgical procedures on the foot and ankle.
Degenerative disorders of the Achilles tendon are common, affecting up to 18% of the adult population. A thorough evaluation including a focused history, physical examination, and diagnostic studies ...helps in choosing the appropriate treatment. Initial treatment is usually nonoperative, consisting of activity modification, bracing, and physical therapy. Patents who fail nonoperative management may be treated operatively with a wide range of procedures from endoscopic surgery to open debridement and tendon transfer. Understanding a patient’s expectations and educating patients about potential treatments and their outcomes enables informed collaborative decision making. This article will review the evaluation and management Achilles tendinopathy and associated disorders.
The pathways for differentiation of human CD4+T cells into functionally distinct subsets of memory cells in vivo are unknown. The identification of these subsets and pathways has clear implications ...for the design of vaccines and immune-targeted therapies. Here, we show that populations of apparently naïve CD4+T cells express the chemokine receptors CXCR3 or CCR4 and demonstrate patterns of gene expression and functional responses characteristic of memory cells. The proliferation history and T cell receptor repertoire of these chemokine-receptor+cells suggest that they are very early memory CD4+T cells that have "rested down" before acquiring the phenotypes described for "central" or "effector" memory T cells. In addition, the chemokine-receptor+"naïve" populations contain Th1 and Th2 cells, respectively, demonstrating that Th1/Th2 differentiation can occur very early in vivo in the absence of markers conventionally associated with memory cells. We localized ligands for CXCR3 and CCR4 to separate foci in T cell zones of tonsil, suggesting that the chemokine-receptor+subsets may be recruited and contribute to segregated, polarized microenvironments within lymphoid organs. Importantly, our data suggest that CD4+T cells do not differentiate according to a simple schema from naïve → CD45 RO+noneffector/central memory → effector/effector memory cells. Rather, developmental pathways branch early on to yield effector/memory populations that are highly heterogeneous and multifunctional and have the potential to become stable resting cells.

The patient was a 35-year-old man who worked as a pipe fitter. He was referred to a physical therapist by an orthopaedic surgeon for a chief complaint of progressively worsening pain in the medial ...aspect of the right distal Achilles tendon and heel that began insidiously 12 months earlier, which was consistent with a diagnosis of insertional Achilles tendonitis. Prior radiographs revealed mild calcification at the insertion of the Achilles tendon. Despite physical therapist intervention for 8 weeks, the patient did not improve. Subsequent magnetic resonance imaging revealed a large multiloculated ganglion cyst in the tarsal tunnel.
