Comparison of Two Techniques for Proximal Margin Analysis of Toe Amputations: A Retrospective Review.

Toe amputations are a common podiatric procedure for treatment of osteomyelitis. Whether or not the surgeon obtains a surgical cure, thus resolving the infection, can be difficult to assess. Obtaining a proximal bone margin can assist the treatment team in deciding the duration of postoperative antibiotics, need for reoperation, and postoperative care. The two senior surgeons use different methods to analyze proximal bone margins. The first surgeon obtains a microbiologic culture from the remaining bone, either at the proximal phalanx or metatarsal head, following the removal of the toe to be reviewed for osteomyelitis. Per the second surgeon's technique, the pathologist only analyzes the proximal aspect of the amputated toe for presence of osteomyelitis. Our goal is to analyze the reoperation and reamputation rates between the techniques in which the proximal margin specimens are obtained. A retrospective chart review was performed on all isolated toe or partial toe amputations from March 2017 to September 2022. There were 115 patients who met inclusion criteria. Reoperation and reamputation rates were analyzed for positive and negative infection margins from intraoperative cultures. Our study found an overall 28% reoperation rate and 26% reamputation rate for the negative margins group. In the positive proximal margin group, there was an overall 48% reoperation rate and 44% reamputation rate. Our analysis did not find a statistically significant difference between the reamputation rate in the negative margins group and the reamputation rate in the positive margins group. In conclusion, our study found that a positive proximal margin for osteomyelitis exhibited a nearly double reoperation and reamputation rate compared to patients with a negative margin, and that one margin analysis technique was not inferior to the other in regards to the need for additional surgeries.

Primary Arthrodesis versus Open Reduction and Internal Fixation for Lisfranc Joint Fracture-Dislocations in Adults: A Systematic Review.

BACKGROUND: The Lisfranc joint is an intricate podiatric medical structure that when injured can prove difficult to treat. No consensus has been established on optimal surgical management for this injury. It is widely debated whether open reduction and internal fixation or primary arthrodesis provides better outcomes for patients. Although literature has been published on this subject, no generalized guidelines have been created. The goal of this study was to analyze high-level meta-analyses to draw conclusions about surgical interventions for Lisfranc joint injuries. METHODS: A literature review was conducted to analyze outcomes of meta-analyses from January 1, 2016, to August 31, 2021. Only high-level evidence that reported at least one of the following outcomes was included: American Orthopaedic Foot and Ankle Society scale score, visual analog scale score, total complication rate, hardware removal rate, revision surgery rate, and secondary procedure rate. RESULTS: Six articles met the inclusion and exclusion criteria and were then analyzed. For all of the outcome measures, primary arthrodesis was equal or superior to open reduction and internal fixation. CONCLUSIONS: We recommend primary arthrodesis over open reduction and internal fixation for adult Lisfranc injuries.

Opioid Prescribing Patterns of Foot and Ankle Surgeons: Single State Review.

The United States is currently in an opioid crisis. In order improve the amount of misuse and overdoses from opioids, some institutions have begun to create protocols based off of state and federal opioid prescription regulations. Our purpose is to analyze the current opioid prescribing patterns in foot and ankle surgery and create an institutional protocol. A survey on current opioid prescribing patterns based on the podiatric surgery was sent out from November 20, 2020 to January 11, 2021 to all members of the North Carolina Foot and Ankle Society. One-hundred surgeons participated in the survey. The most commonly prescribed postoperative pain medication was Hydrocodone/acetaminophen 5 mg/325 mg and the most common quantity was between 21 and 30 tablets. The most common medication for local blocks reported was bupivacaine and lidocaine mixed performed as a block closest to the surgical site. We recommend creating an institutional based opioid protocol for foot and ankle surgeries based off of the procedure performed by the surgeon. We recommend limiting prescriptions to under 30 tablets and utilizing a local or regional pain block for podiatric surgeries.

DPM Foot and Ankle Fellowship Selection Criteria: Survey of Fellowship Directors.

BACKGROUND: A recent increase in podiatric medicine fellowships has occurred as the field continues to progress. Research regarding selection criteria from a fellowship director's perspective for potential fellows is lacking. This study aimed to examine objective and subjective selection criteria that directors consider when selecting applicants for the interview and when ranking prospective fellows after the interview. METHODS: We electronically surveyed American College of Foot and Ankle Surgeons fellowship directors with preselected criteria for granting applicants an interview and for compiling their ranking list after the interview. A Likert scale from 1 (most important) to 5 (least important) was used to prioritize each criterion, an average rating was calculated, and the results were placed in order of importance. RESULTS: The most important selection criteria for granting an interview were quality of residency program (1.985), a written personal statement of reasons for attending that fellowship (2.063), and publications/presentations produced as a resident (2.267). The most important criteria in completing the ranking order after the interview were assessment of applicant's personality (1.111), interview performance (1.173), and expressed interest in program (1.563). CONCLUSIONS: Knowledge of the selection criteria that fellowship directors seek in applicants can assist those who desire to further their training. The selection criteria that program directors seek differed between being selected for the interview, which combined both objective and subjective criteria, and when compiling their rankings after the interview, which included only subjective criteria. Results show more emphasis on subjective selection criteria when directors select applicants for an interview and when ranking applicants after the interview.

Atypical Presentation of Navicular Aneurysmal Bone Cyst in a Symptomatic Pediatric Flatfoot Deformity: A Case Report.

Aneurysmal bone cysts (ABCs) are rare in the foot, accounting for 4% to 6.3% of all ABCs found in the body. Approximately 80% of patients diagnosed with an ABC are in the second decade of life. While benign, pain and deformity are often the presenting symptoms. This report's objective is to describe, to our knowledge, the first reported case of a pediatric navicular ABC in association with pediatric flatfoot deformity that was successfully treated with curettage and bone grafting. An additional goal of the report is to highlight how the diagnosis of these osseous tumors can easily be missed given the overlap in symptoms with pediatric flatfoot deformity. An 11-year-old female presented to clinic with a chief complaint of painful, flatfoot deformity and discomfort to the medial midfoot after walking for more than 2 city blocks. The patient was conservatively treated for pediatric flatfoot deformity at an outside institution and advised that a surgical flatfoot reconstruction would be necessary to relieve her symptomology. On examination, the patient exhibited focal pain to the medial aspect of the navicular. Radiographs revealed an ill-defined, expansile, sclerotic lesion of the navicular, and MRI demonstrated a multicystic lesion filling the navicular, consistent with an ABC. Treatment included curettage and packing with allograft. At 1-year follow-up, the patient is well, with minimal pain and return to full activity without functional limitations. Local recurrence of an aneurysmal bone cyst following curettage and bone grafting is as high as 22% with patient age and lesion size comprising the main risk factors. This report demonstrates successful curettage of an ABC within the navicular and preservation of osseous articulations in a pediatric patient. At 1-year follow-up, the patient had minimal pain with no evidence of recurrence.

Association of calcaneal and spinal fractures.

Calcaneus fractures are common injuries that often lead to chronic pain and long-term disability. Appropriate initial management of calcaneal fractures involves assessment for concomitant trauma (polytrauma), and the vertebral column, in particular, the lumbar spine, is known to be especially vulnerable to simultaneous injury when the os calcis has been fractured. We undertook a retrospective cohort study that included 208 consecutive patients with data recorded in a radiographic database to determine the incidence of concomitant vertebral fracture in association with fracture of the calcaneus. A total of 15 calcaneal fractures (7.21%) were associated with concomitant vertebral fracture, and the lumbar spine was involved in 12 (80%) of these cases. The only clinical variable that was statistically significantly associated with the presence of concomitant calcaneal and vertebral fracture was localization of the vertebral fracture to the lumbar spine (p = .0001). The results of our investigation have indicated that the incidence of concomitant calcaneal and vertebral fractures was significantly lower clinically than the traditional 10% association described in previous studies.
