Background: Digital deformities represent a common presenting abnormality and target for surgical intervention in podiatric medicine and surgery. The objective of this investigation was to compare the radiographic width of the heads of the lesser digit proximal phalanges.

Methods: One hundred fifty consecutive feet with a diagnosis of digital deformity and performance of weightbearing radiographs were analyzed. The maximum width of the heads of the lesser digit proximal phalanges were recorded from the radiographs using computerized digital software.

Results: The mean ± standard deviation of the head of the second digit proximal phalanx was 9.74 ± 0.87 mm (range, 7.94-11.78 mm); the head of the third digit proximal phalanx, 9.00 ± 0.91 mm (range,7.27-10.94 mm); the head of the fourth digit proximal phalanx, 8.49 ± 1.01 mm (range, 5.57-10.73 mm); and the head of the fifth digit proximal phalanx, 8.67 ± 0.89 mm (range, 6.50-11.75 mm). The width of the head of the proximal phalanx decreased from the second digit to the third digit (P < .001), decreased from the third digit to the fourth digit (P < .001), and then increased from the fourth digit to the fifth digit (P = .032).

Conclusions: The results of this investigation provide evidence in support of an anatomical and structural contribution to digital deformities. The width of the heads of the lesser digit proximal phalanges decreased from the second to the third to the fourth toes, and then subsequently increased with the fifth proximal phalangeal head.

Necrotizing fasciitis of the foot is a relatively rare diagnosis and has traditionally been treated with distal amputation. A 30-year-old diabetic man with Charcot-Marie-Tooth muscular atrophy developed necrotizing fasciitis of the dorsal foot and underwent surgical debridement resulting in a significant wound with exposed tendons. Serial debridements were performed, eventually followed by a staged free flap reconstruction using an anterolateral thigh fasciocutaneous flap. After allowing time for flap healing, subsequent staged equinovarus reconstruction was also performed successfully. There were no flap or postoperative complications, and the patient is progressing as expected. Flap refinement procedures have been used to enhance cosmetic and functional outcomes. This report not only showcases the success of a procedure high on the reconstructive ladder in a patient at high risk for complications but also highlights an approach in which functional recovery is also optimized successfully in a planned staged multidisciplinary manner.

Background: Hyperkeratosis is a hypertrophic thickening of the skin. A callus (tyloma) is considered diffuse thickening, whereas a corn-also known as a clavus, heloma durum, or intractable plantar hyperkeratosis (IPK)-is a more focal, circumscribed hyperkeratotic lesion with a central conical core of keratin. Treatment (including surgical excision) of plantar keratoses is often sought because of pain and discomfort. The aim of this study was to collect and chart data regarding the surgical excision of plantar corns. The emerging themes were then mapped so that suggestions for areas of future research could be made.

Methods: A scoping review of the literature was performed using the six-stage methodologic framework (minus stage 6) proposed by Arksey and O'Malley incorporating the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews reporting guideline. A database search by means of the United Kingdom National Health Service Care Advanced Database Search yielded 1,056 articles, 12 of which appeared to be of potential relevance. After removing five duplicate articles, this total was reduced to seven, which were retrieved as full texts. Three were excluded. Thirteen further articles were found through Google Scholar and reference lists from the full texts retrieved to give 17 articles for review. One was discounted as not being in English/irrelevant; and one article did not relate to IPK excision, leaving 15 articles for data extraction.

Results: Iterative charting of the included articles yielded overlapping codes and two main themes. The first theme was closure: by primary intention (with or without a skin flap) or by secondary intention. The second theme was whether excision was performed in combination with IPK excision with other (bony) surgery.

Conclusions: There is modest evidence that excision of the lesion with either primary closure or healing by means of secondary intention can be useful for the management of IPKs. A further consideration is an emerging hypothesis that many of these IPKs are viral in origin, rather than mechanical, which implies that prospective studies are required with cross-reference to lesion excision by anatomical site and histopathologic confirmation of the diagnosis.

Isolated congenital pseudarthrosis of the fibula is a rare entity with a limited number of cases reported in the literature. Treatment is challenging because of recalcitrant nonunion and because no consensus about the best treatment plan exists. We report a case of isolated congenital fibular pseudarthrosis with valgus deformity of the ankle. The patient had a history of two failed operations. We used a novel surgical plan that combined tibiofibular synostosis with fibular segment transfer through a unilateral external fixator. The patient showed good early results with fibular union. We advocate the combination of tibiofibular synostosis and fibular segment transfer to restore the integrity and stability of the ankle in recalcitrant isolated congenital fibular pseudarthrosis cases with a history of failed surgery.

First metatarsophalangeal joint (MPJ) arthritis is a very common form of arthritis seen in the foot. Some signs and symptoms include pain, swelling, decreased passive and active range of motion, difficulty with shoe gear, and so forth. Surgically, options for alleviating symptomatic hallux limitus and arthritis fall into two broad categories: joint sparing and joint sacrificing. In this case study, we present a patient with a bilateral failed total silastic implant of the first MPJ and our proposed revision using an osteochondral bone allograft to fill the deficit left behind from silastic implant removal. The ability for immediate weightbearing and to perform this procedure bilaterally is an advantage to this surgical treatment option compared with other described revision techniques. Postoperatively, the patient has adequate range of motion and no pain when ambulatory. We believe this osteochondral allograft implant may be a viable option for revision first MPJ arthroplasty in select patient populations.

Background: In this study, we aimed to describe a case series of revision first metatarsophalangeal joint fusion with a three-dimensional (3-D)-printed implant for osseous deficits of the first metatarsophalangeal joint. Bone defects of the first ray are a common problem in foot and ankle surgery. Etiologies include nonunion, avascular necrosis, osteomyelitis, failed first metatarsophalangeal joint implant arthroplasty, and failed hemijoint resection arthroplasty. Treatment options include acute shortening, block allograft, block autograft, distraction osteogenesis, vascularized free fibula, Masquelet technique, and partial first-ray amputation. Three-dimensional printing provides an opportunity to improve outcomes, with less donor site morbidity and less extensive recovery time than an external fixation device. It has been used in other facets of foot and ankle surgery with encouraging results.

Methods: Three patients (four feet) underwent revision first metatarsophalangeal joint fusion with a 3-D-printed implant. Reasons for revision included avascular necrosis after distal metatarsal osteotomy in one patient and bone deficit after failed first metatarsophalangeal joint implant in two patients.

Results: All patients had a minimum follow up of 12 months. Two patients had painful hardware and had to undergo revision due to implant design. At most recent follow up all patients were pain free with improved pain scores.

Conclusions: In revisional first metatarsophalangeal joint surgery with osseous deficits, the goal is to restore length and alignment, which improves function of the medial column. Custom 3-D-printed implants for first metatarsophalangeal joint revision can provide an opportunity for improved outcomes and healing.

Background: Online health-related information has become increasingly popular. Social media platforms have great potential to support and change patients' perspective. Plantar fasciitis (PF) is a common disease that is one of the most frequently researched subjects among foot problems. This study aimed to assess the content, quality, and reliability of YouTube videos related to PF and to evaluate whether they reflect current PF treatment guidelines.

Methods: The descriptive cross-sectional study analyzed the most viewed 79 YouTube videos retrieved by using the keyword "plantar fasciitis." The quality, reliability, and content of the videos were analyzed using Global Quality Scale (GQS), the modified DISCERN instrument, the Journal of the American Medical Association instrument, and a content scoring system by two independent physiotherapists. The analyzed videos were divided into three groups according to their GQS score as high, intermediate, and low quality. Also, video parameters were compared between the useful and misleading groups.

Results: Of the 79 analyzed videos, 26 (32.9%) were of low quality, 29 (36.7%) were of intermediate quality, and 24 were of (30.3%) high quality. Most high-quality videos were uploaded by allied health professionals (39.4%). The view ratio and video power index scores were highest in patients. There were significant differences between useful and misleading videos in terms of DISCERN, GQS, and Journal of the American Medical Association scores (P = .000, P = .000, and P = .020, respectively). Almost all of the evaluated videos contain at least one treatment approach.

Conclusions: This study demonstrates that the vast of majority of YouTube videos on PF are useful and comprehensive; also, our results may lead us to propose that the vast majority of the videos reflect current treatment guidelines. Video-based information about PF may provide valuable insight to patients, especially in the absence of direct access to health care by stakeholders.

Background: The fact that lateral malleolar fracture is accompanied by posterior malleolar fracture may adversely affect syndesmosis malreduction rates. We aimed to compare syndesmosis malreduction rates determined on postoperative radiographs between isolated lateral malleolar fractures and lateral malleolar fractures accompanied by posterior malleolar fractures.

Methods: We retrospectively examined 128 operative patients: 73 with isolated lateral malleolar fractures (group L) and 55 with lateral + posterior malleolar fractures (group LP). In group LP, no patients received posterior fragment fixation. In both groups, indirect syndesmosis fixation was performed with a single screw after open reduction and internal fixation of the lateral malleolus. Patient age, sex, fracture side, fracture type (Lauge-Hansen and Danis-Weber classifications), Kellgren-Lawrence osteoarthritis classification, syndesmotic incongruency on postoperative radiographs, syndesmotic malreduction of postoperative fibula fracture, fracture union time, complication rates, accompanying injuries, and preoperative and postoperative radiographic syndesmotic measurements (tibiofibular overlap, tibiofibular clear space, medial clear space) were recorded, and the groups were compared.

Results: Mean ± SD age was 44.32 ± 15.66 years in group L and 48.93 ± 14.03 years in group LP (P = .087). There were no significant differences in preoperative and postoperative tibiofibular distance, tibiofibular overlap, and medial clear space values between groups (P > .05). The prevalence of grade 2 fractures according to the Kellgren-Lawrence classification was significantly higher in group LP (P = .047). Postoperative syndesmosis malreduction was detected in 12 patients in group L and in nine in group LP (P = .991).

Conclusions: In lateral malleolar fractures accompanied by small-fragment posterolateral or avulsion-type posterior malleolar fractures, closed syndesmotic screw fixation does not cause syndesmosis malreduction.

The presence of an os sustentaculum bone is extremely rare. Given the scarcity of clinical literature reporting such a finding, the condition may be misdiagnosed as a fracture of the sustentaculum tali. We describe such an incident in a 16-year-old male athlete presenting for a recent ankle sprain with no other history of trauma or pain on the medial aspect of the ankle. The original computed tomographic scan reported a possible nonunion of a sustentaculum fracture, or peripherally corticated ossification in association with a possible talocalcaneal fibrocartilaginous coalition. Given no history of high-level trauma to the area, the clinical presentation, and the radiographic findings, the more likely diagnosis was confirmed to be an os sustentaculum. The goal of the authors of this article is to report such findings to raise awareness of a rare clinical presentation to avoid misdiagnosis.

Background: Foot type, especially cavus foot, is associated with foot and ankle soccer injuries, such as ankle sprains, ankle instability, and foot and ankle lateral injuries. The aim of this study was to identify risk factors for foot and ankle injuries among soccer players.

Methods: Male and female soccer players, from beginners to semiprofessionals, aged between 10 and 40 years were enrolled in this cross-sectional study. Players filled in questionnaires about their training and injury history. Clinical measurements included foot length, Foot Posture Index-6, and arch height flexibility. Each variable was dichotomized: age (<18 years versus ≥18 years), level of play (AA and below versus AAA and above), foot type (cavus or not), and injury. Injury occurrence was analyzed using χ2 tests between each group of variables, and significance was set at P < .05.

Results: A total of 277 players, including 81 females, volunteered; 147 were younger than 18 years and 180 were AA level or below. Cavus foot prevalence was 30%. In the cavus foot group, 51.8% of players had reached at least an AAA level compared with 27.8% in the normal-arched group (P < .001 [χ2]). Injuries were associated with a cavus foot type (P < .01 [χ2]) and with sex, age, or highest level played (P < .001 [χ2]).

Conclusions: This study identified a high prevalence of cavus foot among soccer players of all ages, with an increased prevalence among higher-level players. The injury risk factors were female sex, older age, playing at a higher level, and cavus feet.
