Background: Tarsal tunnel syndrome (TTS) occurs when an individual suffers from tibial nerve compression at the tarsal tunnel. Symptoms of TTS may include pain, burning, or tingling on the bottom of the foot and into the toes. Tarsal tunnel syndrome can be divided into distal and proximal TTS. Furthermore, a high tarsal tunnel syndrome (HTTS) has also been described as a fascial entrapment proximal to the laciniate ligament at the level of the high ankle. Multiple risk factors, including obesity, have been said to be associated with TTS. This study aimed to determine the frequency of obesity in the form of body mass index (BMI) with HTTS.
Methods: A cross-sectional descriptive study using a nonprobability sampling method retrospectively surveyed the BMI of 73 patients whose clinical presentation suggested HTTS or TTS, and in which electrodiagnostic testing found HTTS. The age of the patients ranged from 25 to 90 years (mean, 56.4 years). Thirty-five patients were men and 38 patients were women.
Results: Based on BMI, nine patients with HTTS had normal weight (12.9%), 17 patients were overweight (23.3%), and the remaining 47 patients were obese (64.3%).
Conclusions: The frequency of obesity in the form of BMI was 64.3% in patients with HTTS, which is a significantly high correlation.
Background: Because ultrasound measurement of plantar fascia thickness is widely used in the diagnosis and evaluation of plantar fasciitis, it is important to understand and minimize the errors that occur with this measurement. The aim of this systematic review was to identify and synthesize studies reporting on intrarater and interrater reliability of ultrasound measurement of plantar fascia thickness.
Methods: After comprehensive searches in the MEDLINE, Embase, and Cochrane Library databases, 11 studies involving 238 healthy participants and 68 patients with pathologic foot disorders were included.
Results: Seven of 11 studies revealed a low risk of bias. Most of the studies reported good to excellent intrarater and interrater reliability for ultrasound measurement of plantar fascia thickness (intrarater intraclass correlation coefficient [ICC], 0.77–0.98; interrater ICC, 0.76–0.98). In addition, two studies on intrarater reliability and one study on interrater reliability showed moderate reliability (ICCs, 0.65, 0.67, and 0.59, respectively). Overall, the standard error of measurement was less than 5% and did not exceed 7%.
Conclusions: The findings of this review suggest that ultrasound measurement of plantar fascia thickness is reliable in terms of both relative and absolute reliability. Reliability can be optimized by using the average of multiple measurements and an experienced operator.
Ankle fractures have been well documented and are common, especially in the elderly, behind hip and distal radius fractures. Open reduction and internal fixation (ORIF) is the standard of treatment for displaced and unstable ankle fractures. Traditionally, ankle fractures in the elderly population have been treated with nonoperative methods; however, nonoperative methods have been associated with increased mortality. Thus, there has been a shift toward operative management for the elderly and less healthy patients. However, these patients often present with more comorbidities that make them not ideal candidates for ORIF of the fracture. Minimally invasive intramedullary nailing of the fibula has gained popularity in recent years for the treatment of displaced ankle fractures. A 72-year-old man presented to the clinic with left ankle pain with a duration of 2 weeks. Radiography revealed a displaced fracture of the left fibula at the level of the ankle joint. This case report documents the surgical treatment of a displaced distal fibula fracture using minimally invasive intramedullary nailing of the fibula. At 4 months’ follow-up, the patient was walking with minimal assistance and weightbearing as tolerated. Left untreated, displaced ankle fractures can be very debilitating, with increased mortality and morbidity, especially in the elderly population. Thus, early diagnosis and surgical treatment of displaced ankle fractures are imperative. The purpose of this report was to raise awareness of minimally invasive fibular nailing as an alternative to ORIF in the treatment of displaced ankle fractures in the elderly.
Nevoid melanoma (NeM) is a rare variant of malignant melanoma characterized by slight cellular atypia, polymorphism, and incomplete maturation. It most frequently occurs on the trunk and arms but rarely on the foot. Here, we report a subungual NeM of the right hallux. A 65-year-old man presented with severe pain of 6 months’ duration to his right great toe following self-treatment for an ingrown nail. He was evaluated and treated with debridement of the toenail at an urgent medical center 3 months prior. However, this had not relieved his pain. The patient also noticed discoloration of his distal great toe over the past 3 months. Removal of part of the ingrown nail revealed a pigmented mass extending distally from the matrix. Surgical excision of the mass was performed because of the concern for malignancy. The diagnosis of NeM was based on histologic analysis along with enhanced diagnostic modalities. The patient was further treated with surgical amputation of the great toe and anti–programmed cell death-1 therapy. The patient had no relapse at 1-year follow-up. Nevoid melanoma is a rare variant of malignant melanoma on the toes, which needs to be differentiated from a nevus with atypia, with a variety of modalities including cellular and molecular profiling. The optimal treatment is amputation.
Opioid treatment agreements are written agreements between physicians and patients that represent strategies enumerating the risks associated with opioid medications. These opioid treatment agreements set expectations and obligations, as well as identify responsibilities for both patient and prescriber for opioid therapy. Some critics assert that these agreements are cumbersome and degrade the patient once they enter into these agreements. A systemic literature search and review using the Preferred Reporting Item for Systematic Reviews and Meta-Analyses (PRISMA) tool was used to find citations describing opioid treatment agreements and their use. Then eligible and appropriate citations were dissected and analyzed. Using the available federal and state opioid prescribing policies, best practice guidelines as well as positive aspects of reviewed literature citations and avoiding bias, degrading, or macroaggression language, a non-cumbersome opioid treatment agreement specific to podiatric medicine was created. A balance argument for the use of opioid treatment agreements to avoid opioid use disorder that is grounded in clinical literature and commentaries are presented. A one-page sensible opioid treatment agreement specific to podiatric medicine, which is similar to more complex cumbersome ones that are found in the literature, and that may be used as part of any podiatric procedural or surgical inform consent, was created and is presented for review. The perception of defending opioid treatment agreements as documents of disclosure to assist patients in their autonomy was offered. Building on the systemic review findings and concept of using elements of disclosure, a model for an analgesic treatment as a one-page informational document to enhance podiatric physicians to create a specific individual analgesic treatment agreement mirroring the scope of podiatric practices that can be incorporated into procedural and surgical inform consent documents was offered.
Podiatric physicians have come to realize that opioid use disorder (OUD) is a public health crisis causing morbidity, mortality, lost productivity, and legal cost in the United States. Opioid analgesics are efficient first-line pain relievers for acute and chronic lower-extremity pain syndrome. Perioperative pain management strategies have been proposed using opioid stewardship, but there are few standardized protocols to guide podiatric medical providers treating patients with OUD. First, we describe the pharmacology of therapeutic agents used as medications for addiction treatment for OUD and substance use disorder (SUD). Second, we offer criteria for selecting acute pain and perioperative management in patients with OUD and SUD per current medical literature. Finally, we review the literature applying opioid stewardship in the context of prescribing opioid analgesics in the presence of OUD and SUD.
Three hypothetical clinical scenarios grounded in clinical-based literature are described with congruent data and founded guidelines. The first and second scenarios describe acute pain and perioperative management in patients with OUD receiving methadone and buprenorphine-naloxone, respectively. The third scenario describes acute pain and perioperative management in a patient with SUD receiving intravenous naltrexone. We hope that the lower-extremity specialist will appreciate that thoughtful management of acute perioperative pain among patients who receive medications for addiction treatment for OUD is critically important given the risks of destabilization during the perioperative period. The literature reveals the lack of rigorous evidence on acute pain management in patients who receive medication for OUD; however, some clinical evidence supports the practice of continuing methadone or buprenorphine for most patients during acute pain episodes.
Atypical Chondroid Syringoma of the Toe
Radiopathologic Correlation
Although chondroid syringoma rarely occurs outside the head and neck, the majority of malignant chondroid syringomas are identified in the extremities. Here, we present a case of atypical chondroid syringoma in the fifth toe. Diagnosis of chondroid syringoma with atypical cells was made following initial excisional biopsy and histology, necessitating repeated surgery for positive margins. In this case report, we examine the radiopathologic correlation of this diagnosis, detail the imaging findings of benign and malignant chondroid syringomas, and highlight how magnetic resonance imaging can be used to guide surgical planning and treatment course of this potentially malignant tumor.
Cognitive Bias in Postoperative Opioid-Prescribing Practice
A Novel Effect
Background: Given that excess opioid prescriptions contribute to the US opioid epidemic and there are few national opioid-prescribing guidelines for the management of acute pain, it is pertinent to determine whether prescribers can sufficiently assess their own prescribing practice. We investigated podiatric surgeons’ ability to evaluate whether their own opioid-prescribing practice is less than, near, or above that of an “average” prescriber.
Methods: We administered a scenario-based, voluntary, anonymous, online questionnaire consisting of five surgery-based scenarios commonly performed by podiatric surgeons. Respondents were asked the quantity of opioids they would prescribe at the time of surgery. Respondents were also asked to rate their prescribing practice compared with the average (median) podiatric surgeon. We compared self-reported behavior to self-reported perception (“I prescribe less than average,” “I prescribed about average,” and “I prescribe more than average”). Analysis of variance was used for univariate analysis among the three groups. We used linear regression to adjust for confounders. Data restriction was used to account for restrictive state laws.
Results: One hundred fifteen podiatric surgeons completed the survey in April 2020. Less than half of the time, respondents accurately identified their own category. Consequently, there were no statistically significant differences among podiatric surgeons who reported that they “prescribe less,” “prescribe about average,” and “prescribe more.” Paradoxically, there was a flip in scenario 5: respondents who reported they “prescribe more” actually prescribed the least and respondents who believed they “prescribe less” actually prescribed the most.
Conclusions: Cognitive bias, in the form of a novel effect, occurs in postoperative opioid-prescribing practice; in the absence of procedure-specific guidelines or an objective standard, podiatric surgeons, more often than not, were unaware of how their own opioid-prescribing practice measured up to that of other podiatric surgeons.
Background: We aim to share our popliteal sciatic nerve block (PSB) experience, which we applied to diabetic and nondiabetic patients in the operating room of our hospital.
Methods: The patients who underwent PSB for foot and ankle surgery between October 1, 2021, and December 31, 2021, in Sakarya University Training and Research Hospital were evaluated retrospectively. All nerve blocks were administered by a single anesthesiologist. Demographic data of the patients and the duration of the operation, the type of operation, the time of application of the nerve block, whether it was single or bifurcation block, and the onset times of motor and sensory block were also recorded in the perioperative period.
Results: It was determined that PSB was applied to 49 patients over a 3-month period. The mean age of the patients was 61.33 ± 14.03 years, and 12 patients (24.5%) were women. The reason why the patients were operated on was amputation in 21 (42.9%) and wound debridement in 27 (55.1%). There were 37 patients in the diabetic group and 12 patients in the nondiabetic group. There was no significant difference between the two groups in terms of demographic data and operation characteristics, but it was observed that there was a significant difference in both sensory and motor block formation times between the two groups (P < .001).
Conclusions: In conclusion, we think that popliteal sciatic nerve block is easy to apply, the complication rate is low, and it is a suitable anesthesia method for patients who will undergo day surgery for foot ulcer.
