Background:The aim of this study was to define the rate of new persistent opioid use and risk factors for persistent opioid use after operative and nonoperative treatment of ankle fractures.Methods:Using a nationwide insurance claims database, Clinformatics DataMart Database, we identified opioid-naïve patients who underwent surgical treatment of unstable ankle fracture patterns between January 2009 and June 2016. Patients who underwent closed treatment of a distal fibula fracture served as a comparative group. We evaluated peritreatment and posttreatment opioid prescription fills. The primary outcome, new persistent opioid use, was defined as opioid prescription fulfillment between 91 and 180 days after the procedure. Logistic regression was used to evaluate the effect of patient factors, and the differences of the effect were tested using Wald statistics. The adjusted persistent use rates were calculated. A total of 13 088 patients underwent treatment of an ankle fracture and filled a peritreatment opioid prescription.Results:When compared with closed treatment of a distal fibula fracture, only 2 surgical treatment subtypes demonstrated significantly increased rates of persistent use compared with the closed treatment group: open treatment of bimalleolar ankle fracture (adjusted odds ratio [aOR], 1.32; 95% CI, 1.10-1.58; P = .002) and open treatment of trimalleolar ankle fracture with fixation of posterior lip (aOR, 1.47; 95% CI, 1.04-2.07; P = .027). Rates were significantly increased (aOR, 1.56; 95% CI, 1.34-1.82; P < .001) among patients who received a total peritreatment opioid dose that was in the top 25th percentile of total oral morphine equivalents. Factors independently associated with new persistent opioid use included mental health disorders, comorbid conditions, tobacco use, and female sex.Conclusion:All ankle fracture treatment groups demonstrated high rates of new persistent opioid use, and persistent use was not directly linked to injury severity. Instead, we identified patient factors that demonstrated increased risk of persistent opioid use. Limiting the peritreatment opioid dose was the largest modifiable risk factor related to new persistent opioid use in this privately insured cohort.Level of Evidence:Level III, retrospective cohort study.
Background: Orthopaedic surgeons are the fourth highest on the list of top prescribers of opioid analgesics by specialty and have a direct impact on opioid-related morbidity in the United States. Operative bunion correction is one of the most commonly performed elective foot surgical procedures in this country. We sought to determine the rate of new persistent opioid use following exposure to opioids after surgical treatment of hallux valgus (bunionectomy) and to identify associated risk factors. Methods: A nationwide U.S. insurance claims database, Truven Health MarketScan, was used to identify opioid-naïve patients who underwent surgical treatment of hallux valgus employing 3 common procedures from January 2010 to June 2015. The rate of new persistent opioid use (i.e., fulfillment of an opioid prescription between 91 and 180 days after the surgical procedure) among patients who filled a perioperative opioid prescription was then calculated. A logistic regression model was used to examine the relationship between new persistent use and risk factors, including surgical procedure, patient demographic characteristics, and patient comorbidities. Results: A total of 36,562 patients underwent surgical treatment of hallux valgus and filled a perioperative opioid prescription. The rate of new persistent opioid use among all patients who filled a perioperative opioid prescription was 6.2%. Patients who underwent treatment with a first metatarsal-cuneiform arthrodesis were more likely to have new persistent opioid use compared with the distal metatarsal osteotomy control group (adjusted odds ratio, 1.19 [95% confidence interval, 1.03 to 1.39]; p = 0.021). Factors independently associated with new persistent opioid use included prescribing patterns, coexisting mental health diagnoses, and certain pain disorders. Conclusions: New persistent opioid use following surgical treatment of hallux valgus affects a substantial number of patients. Understanding factors associated with persistent opioid use can help clinicians to identify and counsel at-risk patients and to mitigate this public health crisis.

Background: Lesser toe plantar plate attenuation or disruption is being increasingly implicated in a variety of common clinical conditions. A multitude of surgical techniques and devices have been recently developed to facilitate surgical repair of the plantar plate. However, the microvascular anatomy, and therefore the healing potential in large part, has not been defined. We investigated the microvasculature of the plantar plate by employing a novel technique involving microvascular perfusion and nano–computed tomography (nano-CT) imaging. Methods: Twelve human adult cadaveric lower extremities were amputated distal to the knee. The anterior and posterior tibial arteries were perfused with a barium solution. The soft tissues of each foot were then counterstained with phosphomolybdic acid (PMA). The second through fourth toe metatarsophalangeal (MTP) joints of 12 feet were imaged with nano-CT at 14-micron resolution. Images were then reconstructed for analysis of the plantar plate microvasculature and calculation of the vascular density along the length of the plantar plate. Results: A microvascular network extends from the surrounding soft tissues at the attachments of the plantar plate on both the metatarsal and proximal phalanx. The midsubstance of the plantar plate appears to be relatively hypovascular. Analysis of the vascular density along the length of the plantar plate demonstrated a consistent trend with increased vascular density at approximately the proximal 29% and distal 22% of the plantar plate. Conclusion: There is a vascular network extending from the surrounding soft tissues into the proximal and distal attachments of the plantar plate. Clinical relevance: The hypovascular midportion of the plantar plate may play an important role in the underlying pathoanatomy and pathophysiology of this area. These findings may have significant clinical implications for the reparative potential of this region and the surgical procedures currently described to accomplish anatomic plantar plate repair.
