Lateral Plantar Artery Aneurysm
A Case Report
We report a case of a true plantar artery aneurysm in an adult. True aneurysms of the inframalleolar vessels are rare. The limited literature on the subject is reviewed, including differential diagnosis and suggested treatment. (J Am Podiatr Med Assoc 97(6): 480–482, 2007)
Skin ulcers can be very painful and detrimental in patients with systemic sclerosis, or systemic scleroderma. A brief review of scleroderma skin ulcers is presented, as well as a case study that demonstrates the effectiveness of becaplermin gel supplemented by oral immunosuppressive agents in the treatment of ulcers resulting from systemic sclerosis. The time to healing (approximately 3 months) was comparable to that associated with the oral agents and surgical interventions specifically designed to help heal scleroderma ulcers. Except for incisional biopsy, no surgical procedures were performed. (J Am Podiatr Med Assoc 92(6): 350-354, 2002)
Background: This retrospective study of a case series analyzed the results from the application of a distally based adipofascial sural flap for nonweightbearing defects of the foot and ankle.
Methods: Twenty-eight patients with post-traumatic ankle and foot defects (ten women and 18 men; age range, 17–63 years) underwent surgery between November 1, 2003, and November 30, 2008. Distally based adipofascial sural flaps were used in ten open fractures, 14 soft-tissue post-traumatic defects, and four deep burns. Defects were on the dorsal side of the foot (eight cases), the lateral malleolus (four cases), the medial malleolus and inframalleolar region (four cases), the Achilles tendon region (eight cases), and the anterior surface of the ankle (four cases). Surgical procedures were performed by a single surgeon (A.M.).
Results: All of the flaps healed uneventfully. There was no partial or total flap loss. All 28 patients walked normally at the time of follow-up. Three delayed healings occurred at the donor site.
Conclusions: This is a homogeneous series of lower-limb reconstructions with the distally based adipofascial sural flap, which permits better analysis of the results. This flap has a constant and reliable blood supply. It can be used for the reconstruction of nonweightbearing foot and ankle regions to avoid the bulky volume of the fasciocutaneous flap in this area and to minimize the donor site scar.

Background
Diabetes-related lower limb amputations (LLAs) are a major complication that can be reduced by employing multidisciplinary center frameworks such as the Toe and Flow model (TFM). In this study, we investigate the LLAs reduction efficacy of the TFM compared to the standard of care (SOC) in the Canadian health-care system.
Methods
We retrospectively reviewed the anonymized diabetes-related LLA reports (2007-2017) in Calgary and Edmonton metropolitan health zones in Alberta, Canada. Both zones have the same provincial health-care coverage and similar demographics; however, Calgary operates based on the TFM while Edmonton with the provincial SOC. LLAs were divided into minor and major amputation cohorts and evaluated using the chi-square test, linear regression. A lower major LLAs rate was denoted as a sign for higher efficacy of the system.
Results
Although LLAs numbers remained relatively comparable (Calgary: 2238 and Edmonton: 2410), the Calgary zone had both significantly lower major (45%) and higher minor (42%) amputation incidence rates compared to the Edmonton zone. The increasing trend in minor LLAs and decreasing major LLAs in the Calgary zone were negatively and significantly correlated (r = -0.730, p = 0.011), with no significant correlation in the Edmonton zone.
Conclusions
Calgary's decreasing diabetes-related major LLAs and negative correlation in the minor-major LLAs rates compared to its sister zone Edmonton, provides support for the positive impact of the TFM. This investigation includes support for a modernization of the diabetes-related limb preservation practice in Canada by implementing TFMs across the country to combat major LLAs.
Background: The deep plantar arterial arch (DPAA) is formed by an anastomosis between the deep plantar artery and the lateral plantar artery. The potential risk of injury to the DPAA is concerning when performing transmetatarsal amputations, and care must be taken to preserve the anatomy. We sought to determine the positional anatomy of the DPAA based on anatomical landmarks that could be easily identified and palpated during transmetatarsal amputation.
Methods: In an effort to improve our understanding of the positional relationship of the DPAA to the distal metatarsal parabola, dissections were performed on 45 cadaveric feet to measure the location of the DPAA with respect to the distal metatarsal epiphyses. Images of the dissected specimens were digitally acquired and saved for measurement using in-house–written software. The mean, SD, SEM, and 95% confidence interval were calculated for all of the measurement parameters and are reported on pooled data and by sex. An independent-samples t test was used to assess for sex differences. Interrater reliability of the measurements was estimated using the intraclass correlation coefficient.
Results: The origin of the DPAA was located a mean ± SD of 35.6 ± 3.9 mm (95% confidence interval, 34.5–36.8 mm) proximal to the perpendicular line connecting the first and fifth metatarsal heads. The average interrater reliability across all of the measurements was 0.921.
Conclusions: This study provides the positional relationship of the DPAA with respect to the distal metatarsal parabola. This method is easily reproducible and may assist the foot and ankle surgeon with surgical planning and approach when performing partial pedal amputation.
Interrater Reliability of Spectral Doppler Waveform
Analysis Among Podiatric Clinicians
Background:
Spectral Doppler ultrasound examination of pedal arteries is one of the most frequently used noninvasive assessment methods by health-care professionals for the diagnosis and ongoing monitoring of people at risk for or living with peripheral arterial disease. The aim of this study was to determine the interrater reliability of the interpretation of spectral Doppler waveform analysis.
Methods:
An interrater reliability study was conducted among five experienced podiatric physicians at the University of Malta Research Laboratory (Msida, Malta). A researcher who was not a rater in this study randomly selected 229 printed spectral Doppler waveforms from a database held at the University of Malta. Each rater independently rated the qualitative spectral waveforms.
Results:
Interrater reliability of the spectral Doppler waveform interpretation was excellent among the five experienced podiatric physicians (α = 0.98). The intraclass correlation coefficient showed a high degree of correlation in waveform interpretation across raters (P < .001).
Conclusions:
This study demonstrates high interrater reliability in visual spectral Doppler interpretation among experienced clinicians. The current foot screening guidelines do not refer to spectral Doppler waveform analysis in their recommendations, which has been shown in studies to be an important modality for the diagnosis of peripheral arterial disease when ankle-brachial pressure indexes are falsely elevated in calcified arteries. If interpreted correctly, the information obtained can provide an indication of the presence of peripheral arterial disease and facilitate early management of this condition.
Behcet's Disease
A Case Report
Behcet's disease is a rare autoimmune systemic vasculitis. It usually presents with a symptom complex involving primarily mucocutaneous lesions, genital lesions, and uveitis. When it involves the lower extremity, venous and arterial disease predominates, and joint involvement occurs in approximately 50% of patients. We present a patient with Behcet's disease who was initially referred to us for chronic toenail pathology.
We report a pseudoaneurysm of the medial plantar artery that developed after percutaneous pinning for a Lisfranc fracture-dislocation in a 68-year-old male. Postembolization ultrasound and arteriography demonstrated successful ablation of the pseudoaneurysm following intra-arterial thrombin injection. Postoperative pulse volume recording and photoplethysmograph of the digits revealed excellent perfusion following ablation. (J Am Podiatr Med Assoc 99(1): 58–60, 2009)
Acral lentiginous melanoma is commonly misdiagnosed, and when detected late it portends a poor prognosis. Acral lentiginous melanoma can be mistaken for verruca, pyogenic granuloma, poroma, an ulcer, or other benign skin conditions. Patients with acral skin growths often present initially to a podiatric physician or their primary care physician. It is at this point when the growth is triaged as benign or potentially malignant. Dermoscopy aids in this decision making. Historically, dermoscopy training has been geared toward dermatologists, but there is increasing recognition of the need for dermoscopy training in primary care and podiatric medicine. Dermoscopy is particularly helpful in pink (amelanotic) growths, which can lack the traditional clinical findings of melanoma. A literature review of acral melanoma and dermoscopy was performed in PubMed. We also describe a case of amelanotic acral melanoma in a 58-year-old with a rapidly enlarging painful mass on her heel. The lesion was initially thought to be a pyogenic granuloma and was treated with debridement (curettage). She was ultimately seen in the dermatology clinic, and the findings under dermoscopy were worrisome for amelanotic melanoma. Biopsy confirmed the diagnosis. The cancer metastasized, and the patient died less than 2 years later.
Nonunion of an Isolated Cuboid Fracture
A Case Report
Nonunion of an isolated undisplaced cuboid fracture is unusual. We report a case of symptomatic nonunion of an isolated cuboid fracture after nonoperative treatment. Fracture union was achieved with surgery, and the patient returned to full activities. (J Am Podiatr Med Assoc 103(3): 233–235, 2013)
