Background: Ultrasound-guided percutaneous fasciotomy and debridement (USPFD) is a minimally invasive treatment for patients with plantar fasciopathy refractory to conservative management. Previous studies have shown clinical improvement with USPFD, but pain relief and patient satisfaction have not been demonstrated beyond 2 years. Methods: This retrospective case series included patients who underwent USPFD at a quaternary academic medical center between April 2013 and January 2018, with refractory plantar fasciopathy and at least 4 years’ follow-up. Patient outcomes were assessed through electronic surveys and telephone interviews. Primary outcome measures included mean changes in visual analog scale pain (VAS-Pain) scores and patient satisfaction via Likert scale. Secondary measures included VAS-Pain with the first 5 steps, VAS-Pain during daily weightbearing, and procedural complications. Results: Seventy unique procedures were identified among 62 patients. Follow-up data were obtained from 51 of 62 patients (82%) who responded to surveys or phone calls. This corresponded to 58 of 70 procedures (83%) at a mean postprocedure follow-up of 6.6 ± 1.4 years. Patients had a mean duration of symptoms of 2.1 ± 3.0 years prior to the procedure. Baseline VAS-Pain was 6.8 ± 2.2 and final follow-up VAS-Pain was 0.7 ± 1.1. At the last follow-up, patient-reported VAS-Pain with first 5 steps was 0.9 ± 1.6 and VAS-Pain with weightbearing through the day was 1.3 ± 1.8. Overall, 91% (53/58) of the procedures were considered successful, where patients responded they were “satisfied” or “very satisfied” and 52 of 58 (90%) procedural responses indicated that based on the outcome, they would recommend the procedure to others. Final follow-up VAS-Pain, VAS-first 5 steps, and VAS-weightbearing, were all improved in the success vs failure groups ( P ≤ .002). No complications were reported. Conclusion: USPFD was associated with high patient satisfaction and durable pain relief for chronic plantar fasciopathy at an average follow-up of 6.6 ± 1.4 years.

Background: Plantar vein thrombosis (PVT) is a rare cause of unilateral plantar foot pain not commonly assessed during sonographic scans for venous thromboembolic evaluation. The present study aims to increase awareness of PVT when evaluating musculoskeletal conditions and to discuss the utility and characteristic imaging findings of PVT on magnetic resonance imaging (MRI). Methods: This is a retrospective chart review identifying patients with suspected PVT via search of a single institution’s radiology reports. Twelve patients had an available lower extremity MRI. These 12 MRIs were independently reviewed by 2 fellowship-trained musculoskeletal radiologists for common imaging characteristics. Of note, only 7 of the 12 available imaging studies contained MRI findings consistent with PVT as determined by the radiology reviewers. For these 7 patients, clinical characteristics were also recorded. Results: Between both radiology reviewers, there was 100% agreement confirming, localizing, and describing the findings of PVT. Of the 7 cases of MRI-confirmed PVT, 6 of 7 studies were performed without contrast and 1 of 7 was performed with and without contrast. The lateral plantar vein was the predominant vein involved in 85.7% (6/7). All 7 cases showed signs of intraluminal signal change, venous enlargement, and muscle edema. Two cases (28.6%, 2/7) displayed collateralization and/or enlargement of surrounding veins. In the only MRI performed with contrast, perivascular enhancement and a filling defect were noted. Conclusion: In the evaluation of a painful foot, an MRI can be used to diagnose PVT reliably and may have several advantages over compression ultrasonography (US) because of its ability to identify other unsuspected etiologies of a painful foot and elimination of technical limitations of compression US in the plantar foot region.

Abstract Objective Ensuring medication delivery to the epidural space is crucial for effective transforaminal epidural steroid injections. Epidural needle placement is determined by injecting a small amount of contrast at the final needle position. The purpose of this study is to illustrate the appearance of contrast flow in the retrodural retroligamentous space of Okada during computed tomography– and fluoroscopy-guided cervical and lumbar transforaminal epidural steroid injections. Design This retrospective study will use a series of cases to demonstrate contrast within the space of Okada during epidural transforaminal steroid injections. Setting Tertiary medical center. Subjects Study subjects are adult patients who underwent transforaminal epidural steroid injection at our institution. Methods Cases were identified through the use of a search engine of existing radiology reports at our institution. Epidural steroid injection procedural reports were searched for the terms “Okada” and “retrodural space.” Images from the procedure were reviewed by the authors (all proceduralists with dedicated training in spinal injections) to confirm the presence of contrast within the space of Okada. Results This case series illustrates six examples of contrast injection into the retrodural space of Okada during cervical and lumbar transforaminal epidural steroid injections. Conclusions Contrast uptake in the retrodural space of Okada may be seen during transforaminal epidural injections. Although relatively uncommon, it is likely underrecognized. It is extremely important that providers who perform transforaminal epidural steroid injections be familiar with this non-epidural contrast flow pattern so they can adjust needle positioning to deliver steroid to the epidural space.

This prospective case series compared the accuracy of ultrasound (US) to magnetic resonance imaging (MRI) in differentiating complete displaced (CD) thumb ulnar collateral ligament (UCL) tears from nondisplaced injuries in 10 patients with suspected traumatic thumb UCL injuries. Ultrasound identified 100% (2 of 2) of MRI‐documented CD tears, both of which were further confirmed during surgical repair. Ultrasound identified the absence of CD tears in the remaining 8 patients. Although MRI is the reference standard imaging modality for characterizing thumb UCL injuries, ultrasound should be considered an accurate, cost‐effective, and alternative imaging modality to differentiate surgical versus nonsurgical thumb UCL injuries.
