Opioid Consumption Patterns and Prolonged Opioid Use Among Opioid-Naïve Ankle Fracture Patients.

INTRODUCTION: Previous literature has demonstrated an association between acute opioid exposure and the risk of long-term opioid use. Here, the investigators assess immediate postoperative opioid consumption patterns as well as the incidence of prolonged opioid use among opioid-naïve patients following ankle fracture surgery. METHODS: Included patients underwent outpatient open reduction and internal fixation of an ankle or tibial plafond fracture over a 1-year period. At patients' first postoperative visit, opioid pills were counted and standardized to the equivalent number of 5-mg oxycodone pills. Prolonged use was defined as filling a prescription for a controlled substance more than 90 days after the index procedure, tracked by the New Jersey Prescription Drug Monitoring Program up to 1 year postoperatively. RESULTS: At the first postoperative visit, 173 patients consumed a median of 24 out of 40 pills prescribed. The initial utilization rate was 60%, and 2736 pills were left unused. In all, 32 (18.7%) patients required a narcotic prescription 90 days after the index procedure. Patients with a self-reported history of depression (P = .11) or diabetes (P = .07) demonstrated marginal correlation with prolonged narcotic use. CONCLUSION: Our study demonstrated that, on average, patients utilize significantly fewer opioid pills than prescribed and that many patient demographics are not significant predictors of continued long-term use following outpatient ankle fracture surgery. Large variations in consumption rates make it difficult for physicians to accurately prescribe and predict prolonged narcotic use. LEVEL OF EVIDENCE: Level III.

Incidental Finding of Plantar Plate Pathology on Routine Magnetic Resonance Imaging of the Foot and Ankle.

BACKGROUND: We hypothesized that there would be a comparable and high incidence of an incidental torn plantar plate on routine magnetic resonance imaging (MRI) in asymptomatic patients. METHODS: We included adult patients undergoing a foot MRI from 2019 to 2020. Based on the documented reason for MRI, patients were divided into symptomatic and asymptomatic. A separate musculoskeletal radiologist re-evaluated MRI images. Findings were categorized as "torn vs intact." We also used the anatomical grading system (AGS). RESULTS: We reviewed 218 records, including 165 asymptomatic and 53 symptomatic patients. The chance of finding a plantar plate (PP) tear on MRI of symptomatic patients was 28% (21% in PP2, 5.7% in PP3, 5.7% in PP4, and 2% in PP5), while PP tear in asymptomatic patients was only apparent in 2% of MRIs (1.5% in PP2, 0 in PP3, 0 in PP4, and 0.6% in PP5). Cohen's kappa coefficient was 0.92, showing excellent agreement between the radiologists. Odds calculation revealed that the chance of finding a torn PP in an asymptomatic patient is 2.5%. In comparison, the chance of finding an intact PP in a symptomatic patient is 72%, showing 2.5 times more likely to find an intact PP than a torn PP in symptomatic individuals. CONCLUSION: Interestingly, there was a low rate of abnormal PP appearance on MRI in both symptomatic and asymptomatic patients, which suggests that the chance of finding a false-positive PP tear in an asymptomatic patient is minimal and probably negligible. LEVEL OF EVIDENCE: Level IV diagnostic.

Self-Reported Pain Tolerance and Opioid Pain Medication Use After Foot and Ankle Surgery.

BACKGROUND: Orthopaedic surgeons must consider their postoperative pain management strategies to minimize harm from prescription opioid use. Patients often reference their pain threshold to predict how they will tolerate surgical pain and the need for postoperative analgesia, but the direct relationship between these factors has not yet been studied. The purpose of this study was to determine the relationship between patients' self-reported pain tolerance and prescription opioid usage after foot and ankle surgery. METHODS: This is a retrospective follow-up of a prospective cohort study of adult patients who underwent outpatient foot and ankle surgeries. Patient and procedural demographics, opioid pills dispensed, and opioid pills consumed by the first postoperative visit were obtained. Patients were contacted at a mean of 13.1 ± 4.0 months postoperatively and asked to respond to the qualitative statement "Pain doesn't bother me as much as it does most people." Patients were also asked their quantitative pain threshold (0-100), with 0 being "very pain intolerant" and 100 being a "very high pain tolerance," as well other questions regarding past surgical and narcotic consumption history. RESULTS: Of the 700 survey respondents, the average age was 50.9 years and 34.7% were male. Bivariate analysis determined that predictors of lower postoperative opioid consumption included higher quantitative (P = .047) and qualitative (P = .005) pain tolerance scores. Multivariate analysis for the entire cohort demonstrated that higher qualitative pain threshold was associated with lower postoperative opioid consumption (P = .005) but this did not meet statistical significance as an independent predictor of the top quartile of pill consumers. CONCLUSION: Assessment of both qualitative and quantitative score of patients' pain threshold prior to surgery may assist the surgeon in tailoring postoperative pain control. Additionally, asking this question can create an opportunity for educating patients regarding responsible utilization of narcotic medication. LEVELS OF EVIDENCE: Level III.

High Prevalence of Degenerative Changes at the Metatarsal Head Sesamoid Articulation Found During Hallux Valgus Correction Surgery.

Background. Despite the absence of complications and a restoration of normal hallux alignment, some patients have suboptimal outcomes from hallux valgus correction surgery. One risk factor for persistent pain may be the presence of arthritic changes at the metatarsal head articulation with the sesamoids, an area not easily assessed with standard radiographs unless dedicated sesamoid views are obtained. In this study, we prospectively evaluated the metatarsal head for degenerative changes during hallux valgus correction surgery and identified preoperative risk factors associated with these changes. Methods. We prospectively evaluated 200 feet in 196 patients who underwent hallux valgus surgery intraoperatively for the pattern and severity of arthritic changes at the metatarsal head. Mann-Whitney U testing was implemented to compare differences in arthritic scores between preoperative deformity groups. The Spearman correlation test was used to determine the association between age and preoperative deformity with the severity of degenerative changes. Results. More than half of all feet assessed had severe arthritic changes at the plantar medial aspect of the metatarsal head and 40% of feet at the plantar lateral aspect. Age and intermetatarsal angle were found to be positively correlated with arthritis in this area. Conclusion. Our prospective study has demonstrated the high prevalence of arthritic changes at the metatarsal head sesamoid articulation and the positive influence of age and severity of deformity on metatarsal head arthritic changes seen during hallux valgus correction surgery. Furthermore, these arthritic changes were found to have no significant influence on preoperative functional and pain levels.Levels of Evidence: Level IV: Case series.

Coding Education in Residency and in Practice Improves Accuracy of Coding in Orthopedic Surgery.

The goal of training in orthopedic residency is to produce surgeons who are proficient in all aspects of the practice of orthopedic surgery; however, most residents receive either inadequate or no training in medical coding. The purpose of this study was to determine how well orthopedic residents code when compared with practicing surgeons and to identify whether coding education improves accuracy in medical coding. A mock coding survey was developed using commonly encountered orthopedic clinical scenarios. The survey was distributed to orthopedic trainees post-graduate years (PGY) 1 to 6 at 2 training programs and to attending surgeons. Results were analyzed in 3 groups: junior residents (PGY 1-3), senior residents (PGY 4-6), and attending surgeons. Overall and subcategory scores of (1) type of visit, (2) modifiers, (3) Evaluation and Management (E/M), and (4) Current Procedural Terminology code identification were recorded. Participants were also asked if they had ever received various forms of coding education. Sixty-seven total participants were enrolled, including 28 junior residents, 24 senior residents, and 15 attendings. Practicing surgeons performed significantly better than both senior (P<.027) and junior (P<.001) residents in all categories, with a mean overall correct response rate of 72.8%, 51.0%, and 47.4%, respectively. Any form of coding education was associated with a significantly improved overall score for residents (P=.013) and a nonsignificant increase for attending surgeons (P=.390). This study demonstrates that residents performed poorly when identifying proper billing codes for common procedures and encounters in orthopedic surgery. Further, those participants who received coding education did better than those who did not. [Orthopedics. 2020;43(6):380-383.].

Ankle Arthrodesis Through a Fibular-Sparing Anterior Approach.

BACKGROUND: The open anterior approach to ankle arthrodesis offers a technique that provides several advantages for surgeons, such as easier visualization of the joint for deformity correction and preservation of the malleoli for potential future conversion to total ankle arthroplasty. The purpose of this study was to evaluate clinical, radiographic, and functional outcomes in a large series of patients undergoing open ankle arthrodesis via a fibular-sparing anterior approach. METHODS: A retrospective review was performed of patients undergoing primary ankle arthrodesis with a single fellowship-trained foot and ankle orthopedic surgeon between 2009 and 2017. Patients were excluded if an approach other than anterior was performed. Patient-reported outcome measures (Foot and Ankle Ability Measure-Activities of Daily Living [FAAM-ADL], Short-Form 12 [SF-12], and visual analog scale [VAS] pain) were subsequently collected at a minimum of 24 months (2 years) following index surgery, along with outcome satisfaction and likelihood to repeat surgery. Fusion of the tibiotalar joint at the time of last radiographic follow-up was also assessed. Paired t tests were performed to assess change in pre- to postoperative outcomes, while linear regression analysis was performed to identify any patient factors associated with outcomes. Eighty-one patients, including 31 women and 50 men, with a mean age of 51.5 years and a mean follow-up of 58.9 (range, 24-104) months, were included. RESULTS: Sixty-two patients reported significant improvement in mean FAAM-ADL (P < .0001), SF-12 Physical Composite Scale (P < .0001), and VAS pain (P < .0001), while the SF-12 Mental Composite Scale also improved, though not significantly (P = .2854). Twelve patients (14.8%) experienced complications following their arthrodesis procedure. Seventy-nine patients (97.5%) achieved fusion at their last radiographic follow-up. Multiple linear regression analysis revealed age (B = 0.071 [0.004, 0.128]; P = .0373) to have a positive association with postoperative VAS pain. CONCLUSION: Ankle arthrodesis utilizing a fibular-sparing anterior approach combined with the transarticular screw fixation technique offers surgeons several advantages, along with a low postoperative complication rate, high rate of radiographic evidence of joint fusion, and substantially large improvement in pain and functional levels.

When is it Safe to Drive After Total Ankle Arthroplasty?

BACKGROUND: With the increase in the number of total ankle arthroplasties (TAA), guidelines on when physicians should begin to consider patients' return to driving are valuable. Further, due to sagittal motion strength, the ankle is the most important mover in braking motions over the knee and hip. QUESTIONS/PURPOSES: (1) Does brake-reaction time return to a safe value within 6 weeks of TAA? (2) Are there factors associated with a delay of return of brake-reaction time to safe values after TAA? METHODS: After obtaining institutional review board approval for the study, we prospectively recruited 60 patients undergoing right TAA. A large proportion of the patients undergoing TAA during the period were recruited. Patients who had extensive concomitant surgery, such as triple arthrodesis or tibial osteotomy, were excluded from the study. Patients were between 43 and 83 years old (median, 63 years), and 35 (59%) were men. Brake-reaction time was tested at 6 weeks postoperatively and repeated weekly until patients achieved a passing brake-reaction time. A control group of 20 volunteer participants matched for age and sex who did not have right lower-extremity pathology or pain were used to establish a passing brake-reaction time of 0.850 seconds. Patients were given a novel driver-readiness survey to complete; a score of 10 of 15 points or higher was considered a passing score. The following factors were explored for their association with brake-reaction time: age, American Orthopaedic Foot and Ankle Society (AOFAS)-Hindfoot assessment and VAS for pain via a patient-reported survey, and ankle plantarflexion and dorsiflexion via dedicated weightbearing lateral radiographs made with the ankle in maximum plantarflexion and dorsiflexion. RESULTS: At 6 weeks postoperatively, 92% of patients (54 of 59) achieved a passing brake-reaction time and were considered able to drive safely, and the mean brake-reaction time of the patients with a passing brake-reaction time was 0.626 seconds (± 0.111). At 9 weeks, all patients who completed the study achieved a passing brake-reaction time. Patients with a failed brake-reaction time at 6 weeks had greater median VAS scores for pain (3 [interquartile range 2 to 7] versus 1 [IQR 0 to 3]; p = 0.022) and diminished ankle plantarflexion (14° [± 5°] versus 24° [± 10°]; p = 0.037) compared with those with a passing brake-reaction time at that time point. All five patients with a failed brake-reaction time also had a failing score for the driver-readiness survey. CONCLUSIONS: More than 90% of patients in this series achieved a safe brake-reaction time within 6 weeks of TAA, and those who did not were more likely to have had more pain and a stiffer ankle. Surgeons might counsel patients with persistent pain and stiffness at 6 weeks to delay driving for an additional 3 weeks, since by 9 weeks after TAA, all patients in this series had a brake-reaction time comparable with patients who had not undergone surgery. Future studies might elucidate what key gaps in knowledge remain and determine a practical way to answer these questions. LEVEL OF EVIDENCE: Level II, therapeutic study.

Brake Response Time Recovery After Achilles Tendon Repair.

Background. This study evaluated when patients' brake response time (BRT) recovers after right Achilles repair. Methods. Institutional review board-approved prospective study of 60 patients. Assessments included visual analogue scale pain (VAS) score, Achilles Tendon Total Rupture Score (ATRS), and a driver readiness survey. Emergent brake pedal operation was simulated at 6 weeks postoperatively and repeated until patients achieved a passing BRT. Results. Fifty-seven patients completed the study. At 6 weeks, 54 of 59 (91.5%) patients had a passing BRT with a mean of 0.60 seconds (SD 0.08 seconds). Five (8.5%) patients had a failing BRT with a significantly higher mean of 0.95 seconds (SD 0.13 seconds, P = .01). At first testing, all patients were ambulating in a walking boot with removable heel wedges. Those who passed were using significantly fewer wedges (mean 1.9 vs 2.6 wedges, P = .04). Mean VAS pain scores (Passed: 1.1, SD 1.57, vs Failed: 2.8, SD 3.35, P = .32) were not significantly different. The mean ATRS was significantly lower among those who passed (63.7, SD 16.7, vs 85.4, SD 11.1, P = .01. Three patients repeated testing at a mean 7.3 weeks (range 6.7-8). All achieved passing times (mean 0.68 seconds, range 0.55 to 0.77 seconds). The driving readiness survey was 100% sensitive but 31.3% specific for passing BRT. Its positive predictive value was 80%, and its negative predictive value was 100%. Conclusion. BRT normalizes around 6 to 7 weeks after open right Achilles tendon repair. The ATRS and driver readiness questionnaire corresponded to achieving a passing BRT. Levels of Evidence: Prognostic Level II: Prospective Cohort Study.
