Ethnopharmacological Relevance: Syzygium cumini (L.) Skeels is an important medicinal plant utilized in the health care systems of Pakistan, India, Sri Lanka, and Bangladesh. S. cumini have been used to treat renal issues, indigestion, diabetes, dysentery, and employed in folk medicine to treat inflammations. It is known to anticipate antioxidant, anti-inflammatory, anticancer, anti-diabetic, anti-bacterial, antifungal, activities, and radioprotective activities., Material and Methods: We examined the in vitro anti-inflammatory activities of S. cumini fruit extracts, evaluated using membrane stabilization, egg albumin denaturation, and bovine serum albumin denaturation assays. In vivo anti-inflammatory activity was also assessed, using murine models of carrageenan, formaldehyde, and PGE 2 induced paw edema. Fractionation of active extracts was performed using HPLC, followed by LC-ESI-MS/MS analysis to identify the bioactive compounds responsible for anti-inflammatory activity., Results: The crude methanolic extract showed stronger in vitro and in vivo anti-inflammatory activities compared to other extracts. The most potent effects were observed in the formaldehyde induced paw edema assay wherein methanolic extract and standard indomethacin induced 72% and 88% inhibition against paw edema volume in comparison to control (normal saline) respectively. In the bovine serum albumin denaturation assay the methanolic extract induced 82% inhibition against denaturation as compared to control (phosphate buffer) while standard diclofenac sodium induced 98% inhibition. In contrast, 50% v/v MeOH:H 2 O or 100% dichloromethane extracts displayed moderate to weak effects in the anti-inflammatory models. HPLC fractionation provided 6 active sub-fractions, four (MF2, MF3, MF6, MF7) from the 100% methanolic extract and two (HAF1, HAF3) from the 50% methanolic extract. The MF2, MF7, and HAF1 sub-fractions displayed potent activity in all studied in vitro assays. LC-ESI-MS-MS analysis tentatively identified delphinidin 3-glucoside, peonidin-3,5-diglucoside, gallic acid, liquitrigenin, scopoletin, umbelliferon, and rosmanol from the 100% methanolic fractions. Myricetin, catechin, quinic acid, chlorogenic acid, ellagic acid, gallic acid, and caffeic acid were identified in the 50% methanolic fractions., Conclusions: These results demonstrate that S. cumini fruit extracts are a rich source of bioactive compounds that are worthy of further investigation as leads for anti-inflammatory drug discovery., (Copyright © 2021.

Aim: To evaluate the impact of surgical debridement on the microbiology of resection margins of an infected diabetic foot ulcer and to compare the use of marginal sampling as a guide for antimicrobial therapy., Methods: Forty consecutive participants were studied. Tissue samples from infected diabetic foot ulcers were obtained at first contact by podiatrists. After surgical debridement to macroscopically healthy tissue, multiple samples were obtained from the margins of the residuum and also from excised non-viable tissue. Debridement was done by a single surgeon. Bacterial species were classified according to pathogenic potential a priori into Red Group-Definite pathogen causing infection, Yellow Group-Likely to be causing infection if present in more than one specimen and Green Group -Commensals, not causing infection., Results: There was a relative reduction of 49% (p = 0.002) in bacteria in the most pathogenic (red) group, and 59% (p = 0.002) in the yellow group in podiatry samples compared with resection specimen. Positive cultures from margins of the residuum were observed in 75% of cases. There was a relative reduction of 67% (p = 0.0001) in bacteria in the red and 48% (p = 0.06) in the yellow group in marginal samples from the residuum compared with podiatry samples., Conclusions: After surgical debridement to healthy tissue, positive cultures from marginal tissue samples provided vital information on the presence of pathogenic bacteria. This allowed antibiotics to be individualised post-surgical debridement., (© 2020 Diabetes UK.)

Background: This study aimed to clarify the morphological characteristics of the Lisfranc ligament and the cuneiform 1-metatarsal 2&3 plantar ligament (CMPL)., Methods: Forty legs from 20 cadavers were examined. Classification proceeded according to the number of fiber bundles in the Lisfranc ligament and the CMPL. Morphological features measured were fiber bundle length, width, thickness, and angle., Results: In Type I-a, the Lisfranc ligament and the CMPL were a single fiber bundle; in Type I-b, the Lisfranc ligament was a single fiber bundle, and the CMPL was two fiber bundles; in Type II-a, the Lisfranc ligament was a two fiber bundle, and the CMPL was a single fiber bundle; in Type II-b, the Lisfranc ligament and the CMPL were two fiber bundles; in Type III-a, the Lisfranc ligament was three fiber bundles, and the CMPL was a single fiber bundle; in Type III-b, the Lisfranc ligament was three fiber bundles, and the CMPL was two fiber bundles; in Type IV, the Lisfranc ligament and the CMPL could not be separated. Type I-a was seen in 37.5%, Type I-b in 10%, Type II-a in 30%, Type II-b in 7.5%, Type III-a in 7.5%, Type III-b in 2.5%, and Type IV in 5%. The Lisfranc ligament was significantly larger than the CMPL in total fiber bundle width, total fiber bundle thickness, and total fiber bundle angle., Conclusion: The Lisfranc ligament had up to 3 fiber bundles and the CMPL had one or two fiber bundles; classifications were four types and two subgroups.

Crucifixion was a widely used form of execution for capital crimes in antiquity. Civilizations and empires perfected the technique, leading to centuries of discussions, controversies, and questions, many of which concerned the death of Jesus Christ. To this day, much remains to be discovered in both religious and scientific realms. However, the aim of this study is to discuss such facts as are known from the medical perspectives of clinical anatomists. Nails/spikes were driven through the hands/wrists and feet of five adult cadavers, and the cadavers were then dissected to observe the anatomical structures that had been injured or placed at risk for injury. While many historical and archeological facts remain to be discovered, we hope that this cadaveric study will enhance our modern understanding of ancient practices from a medical and anatomical perspective.

A 17-year-old boy was referred after jumping from a ladder onto the ground, crushing a medical thermometer with his right foot. Some days later, he complained of loss of appetite and weakness. A radiograph of the affected foot demonstrated radiopaque densities. Blood and 24-h urine assays for mercury demonstrated toxic levels. Chelation therapy cured the patient dramatically.

Introduction: Degloving injuries of the foot involve the management of extensive soft tissue and osseous damage secondary to significant forced avulsion of soft tissue, which can present a major challenge for the surgeon. Surgical procedures on pediatric foot degloving involving split-thickness and/or full-thickness skin grafts and rotational flaps can result in negative consequences, such as donor site comorbidities and psychosocial implications when the pediatric patient returns to daily life., Case Report: The authors report the case of a 16-year-old girl with no past medical history who sustained an extensive degloving injury to her right foot involving severe subcutaneous and muscular soft tissue disruption and contamination. The initial treatment consisted of debridement, copious irrigation, primary wound closure at several sites, and application of an extracellular matrix (ECM) substitute graft. Shortly thereafter, secondary treatment consisted of application of primary musculoskeletal repair, negative pressure wound therapy (NPWT), and application of a dermal regeneration template. Over the 5-month course of treatment, an additional 3 trips to the operating room occurred, involving serial irrigation and debridement, NPWT application, and dermal/ECM substitute graft applications, leading to full epithelialization., Conclusions: To the best of the authors' knowledge, this is the first reported case in which an instance of pediatric foot degloving is presented with serial debridement, NPWT, and biological dressings, resulting in no additional plastic surgical techniques needed to provide return to functional outcome.

We present an illustrative case of unintentional burns to the feet of a 15-month-old child following the application of raw garlic as a home remedy for fever. We provide an overview of the historical medicinal uses of garlic as well as its unintended adverse effects. This case underscores the importance of clinicians' ability to recognize unusual presentations of injury due to culturally based practices that require care in emergency settings. This is particularly important in patient populations for whom abusive etiology would be considered.

Case: A 21-year-old, active duty male sustained an irreducible, complex Lisfranc fracture-dislocation with distal extrusion of his intermediate cuneiform. He was treated in a staged manner with external fixator placement, followed by an extended midfoot fusion with autograft bone. At 19 months, he could perform all activities of daily living independently with minimal pain using an Intrepid Dynamic Exoskeletal Orthosis., Conclusions: Complex Lisfranc injuries are severe and often result in chronic pain and disability after operative management. To our knowledge, this is the only case report describing a Lisfranc fracture-dislocation with a distally extruded intermediate cuneiform treated with a fusion.

Background: The purpose of this article was to introduce calcaneal lengthening for partial traumatic loss of the calcaneus. Effectiveness with the use of the technique was also assessed., Methods: From January 2013 to May 2016, calcaneal lengthening was performed in 15 patients who sustained a partial traumatic loss of the tuberosity portion of calcaneus. There were 13 men and 2 women with an average age of 36 years (range, 19-53 years). Combined Achilles tendon rupture was noted in 7 patients, and the tendon was reinserted to the calcaneus before calcaneal lengthening. Calcaneal lengthening was performed using an Ilizarov frame. Clinical outcome was assessed based on the American Orthopedic Foot and Ankle score., Results: The mean loss of calcaneus was 27% (range, 19%-35%). Calcaneal lengthening (mean total time is157 days; range, 111-226 days) included three periods, i.e., latency (mean 7 days; range, 7-9 days), distraction (mean 43 days; range, 32-57 days), and consolidation (mean 108 days; range, 84-162 days). The mean amount of lengthening was 28% (range, 19%-38%). The mean follow-up duration was 25 months (range, 24-27 months). Based on the American Orthopaedic Foot and Ankle, there were 8 excellent, 6 good, and 1 fair result., Conclusions: For the treatment of partial traumatic loss of the calcaneus, calcaneal lengthening using an Ilizarov frame is a preferable technique to restore the length of calcaneus and foot function., (Copyright © 2019 Elsevier Ltd.

The proximally based medial plantar flap is considered to be the reference standard for heel reconstruction. Although less well-studied, a distally based medial plantar flap is a suitable alternative when used to cover a distal foot defect, especially of the hallux, first metatarsal, or metatarsophalangeal joint. Our objective was to provide a complete description and propose a classification of the different surgical procedures used to harvest this flap. A review of the data reported in the MEDLINE database until May 2017 concerning the distally based medial plantar flap was performed. We have illustrated the different surgical procedures through a case series. Three approaches or "types" of flap have been described, and we have proposed a classification for reconstructive surgeons. In type 1, the plantar pedicle is ligatured before division into the medial and lateral plantar artery. In type 2, the medial plantar pedicle is cut proximally just after division. In type 3, the flap is harvested to include the fasciocutaneous perforator vessels, as an advancement flap or a propeller perforator flap. A distally based medial plantar flap affords adequate and reliable coverage of the weightbearing zone. Because the donor site drawbacks are minimal, this flap is a useful option for distal foot reconstruction, and reconstructive surgeons should remember this flap. The type 1 flap appears to be associated with a minimal risk of flap necrosis, even in those with diabetes or arteriopathy, and can cover even the most distal defect., (Copyright © 2018 The American College of Foot and Ankle Surgeons.

Hand and foot burns in children are difficult to dress. The authors have developed a soft casting technique to manage burns to these areas. The aim of this study is to report the outcomes using weekly dressing changes with a soft casting technique to manage pediatric hand and foot burns in the outpatient setting. A retrospective chart review was performed on children with burns to the hands or feet, who underwent dressing changes with a soft casting technique at the Children's Hospital Colorado Burn Center. Soft casting was performed by placing antibiotic ointment-impregnated nonadherent gauze over the burn wound(s), wrapping the extremity using rolled gauze, applying soft cast pad, plaster, soft cast tape, and an elastic bandage. This was changed weekly. Two hundred ninety-eight children with hand burns had a mean age of 16.8 ± 2 months. Two hundred forty-eight children had partial thickness burn injuries (83%), 50 had full thickness burn injuries (17%), and the mean total body surface area (TBSA) was 1 ± 2.4%. The mean time to heal was 10.1 ± 1.7 days for all subjects. Sixty-six children with foot burns were identified with a mean age of 24 ± 2.6 months. Forty-six children had partial thickness injuries (70%), 20 had full thickness burn injuries (30%), and the mean TBSA was 2.3 ± 2.9%. The mean time to heal was 14.1 ± 2.2 days for all subjects. Weekly dressing changes using a soft casting technique are effective for the outpatient management of pediatric hand and foot burns. This method avoids costly inpatient hospital care, reduces the number of painful dressing changes, and allows children to heal in their own environment.

Repairing soft tissue loss in feet's anterior and middle parts has become a problem, especially for children. We observed the feasibility and clinical effects of superficial peroneal fasciocutaneous flap pedicled with terminal perforating branches of peroneal artery for repairing children's feet.Between January 2015 and December 2016, soft tissue loss in anterior and middle regions of feet were repaired using superficial peroneal fasciocutaneous flap pedicled with terminal perforating branches of peroneal artery in 8 children with a median age of 6.5 [4-9, interquartile range (IQR) = 3] years. The skin of lower leg was intact, and the soft tissue loss area was located in the anterior and middle regions of feet with a size of 5 cm × 4 cm to 11 cm × 7 cm combined with the exposure of tendons and joints in all the 8 children. On the basis of the conditions above, there were no indications of free skin grafting. Foot wounds were repaired all with the superficial peroneal fasciocutaneous flap pedicled with terminal perforating branches of peroneal artery (6 cm × 5 cm to 12 cm × 8 cm), and then the donor area was sutured to narrow the donor area followed by intermediate split thickness skin graft. The perforating branch trunk of peroneal artery was used as a rotation point (4 cm above the lateral malleolus) in 5 children and descending branch of perforating branch of peroneal artery as a rotation point (2 cm under the lateral malleolus) in 3 children.All flaps survived with primary healing in the 8 children. Postoperative median 7.5-month (3-12, IQR = 4.5) follow-up indicated that flap color and texture were fine, the appearances of donor and recipient areas were satisfactory, wearing shoes was not affected, and walking function and foot blood circulation were normal.For intractable soft tissue loss in the anterior and middle regions of children's feet, superficial peroneal fasciocutaneous flap pedicled with terminal perforating branches of peroneal artery can improve recipient area appearance and walking function because it has the characteristics of reliable blood supply and convenient rotation. It is worth using this method widely in clinics.

Introduction: The deep inferior epigastric perforator (DIEP) flap is one of the most commonly utilized flaps of reconstructive surgery. Although the horizontal flap design is the most commonly used, this flap can be vertically designed to avoid drawbacks such as excessive tissue dissection, relatively reduced flap perfusion, and scarification of the contralateral flap opportunity. The aim of this report is to present our case series for foot and ankle reconstruction with vertical designed DIEP flap., Patients and Methods: The free vertically designed DIEP flaps (VDIEP) were used in eight patients (7 male, 1 female) whose age is in a range of 20-66 years for soft tissue reconstructions in the ankle and foot region over a five-year period. The range of defects' size was from 8 × 5 cm to 15 × 7 cm and the causes were electrical burn, trauma and diabetic foot infections., Results: Flap dimensions varied from 10 × 6 cm to 17 × 9 cm. All the flaps had two or more perforators, and all flaps survived completely. There were no early or late complications. We followed up the patients for 10 months in average. We observed no functional problems, especially in main motions of foot and ankle like eversion, inversion, flexion or extension except one patient. Donor site scars were acceptable in all patients., Conclusions: The VDIEP flap may be an option for selected lower extremity soft tissue reconstructions, and it may be an alternative to classically designed abdominal flaps., (© 2017 Wiley Periodicals, Inc.)

Background: Defects in the weight-bearing region of the foot sole can represent a substantial restriction in quality of life and pose a challenge for reconstructive plastic surgery. The purpose of this article is to report the authors' experience with the use of the medial plantar artery perforator flap for reconstruction of defects of the foot sole in three different regions: heel, middle foot sole, and plantar forefoot., Methods: From January of 2003 to May of 2016, 28 patients (13 male and 15 female patients) with an average age of 54 years (range, 12 to 84 years) underwent reconstruction with 28 medial plantar artery perforator flaps. Twenty-six flaps were harvested as pedicle perforator flaps and two as free perforator flaps. All flaps were raised from the ipsilateral instep area. The defect locations included the heel (20 cases), middle foot sole (four cases), and forefoot (four cases). The causes of reconstruction were tumors in 18 patients, decubitus in eight patients, and trauma in two patients., Results: The flap sizes varied from 2.5 × 2.5 cm to 5.5 × 9.5 cm. All of the flaps survived completely after surgery, apart from one. The donor sites were all covered with a split-thickness skin graft. Follow-up observations were conducted for 4 to 12 months, and all patients had good functional recovery with satisfactory cosmetic results., Conclusion: The medial plantar artery perforator flap can be considered an optimal method of foot sole reconstruction not only for covering the weight-bearing area of the heel but also for the middle and forefoot plantar region., Clinical Question/level of Evidence: Therapeutic, IV.

Septic shock sometimes starts with unspecific symptoms that hamper the clinical diagnosis and, therefore an appropriate treatment. When the septic shock follows a fulminating course with a fatal outcome, the etiological diagnosis has to be conducted post-mortem. Sudden unexpected deaths in children and young adults are frequently the object of medico-legal autopsies. Some sudden unexpected deaths have an infectious origin, which requires further analyses, including microbiology, to establish the cause of death. Here, the case of a fatal septic shock in a 19-month old male infant is presented. After a mild foot injury, an infection by Streptococcus pyogenes progressed to septic shock with a fatal outcome as post-mortem studies demonstrated.

Background: There were very few options available for distal foot and toe defects that required a vascularized flap for coverage. As such, the use of a free flap was often justified in this region of the foot. The use of perforator flaps has created a new subset of local tissue transfer alternatives that increases the potential that the difficulties associated with microvascular tissue transfers could be avoided. The first dorsal metatarsal artery (FDMA) perforator flap was one variant of this new type of tissue transfer. The aim of this report was to describe our experience using FDMA perforator flap to cover great toe defect., Methods: A standard FDMA flap from the dorsum of the foot was raised in reversed fashion based on the distal communicating branch or "perforator" from plantar foot circulation in two patients with great toe defect., Results: Salvage of the great toe was achieved in both patients. FDMA perforator flap achieved both reconstructive goals, and the donor site closure can be successfully performed without tension. Donor site healing was achieved in both patients with no associated complications by the 1-year follow-up., Conclusions: FDMA flap can be successfully used as a local flap to cover distal foot and toe wounds. However, direct donor site closure can be problematic and may need skin graft.

Aim: To evaluate a moisturizer containing urea, glycerine and petrolatum for healing deep open fissures on the feet of people with diabetes. If left untreated, open fissures, an entry point for bacteria, can lead to infection, ulceration and further complications., Methods: This randomized, double-blind, multicentre study at 19 hospitals, general practices and diabetologists in France and Belgium included participants with diabetes and a deep open target fissure on their heel. Participants were randomized to test cream or placebo (1 : 1) for 4 weeks. Complete target fissure healing after 4 weeks (primary criterion) and 2 weeks, target fissure closure, overall fissure healing and xerosis were assessed., Results: Some 167 participants were randomized (80 to test cream; 87 to placebo); all were included in the efficacy analyses. The percentage of participants with complete target fissure healing after 4 weeks was higher with test cream than placebo (46.3% vs. 33.3%): the difference did not reach statistical significance (P = 0.088). Fewer participants still had a deep open target fissure with test cream than placebo, the difference was statistically significant and clinically relevant after 2 (24.7% vs. 42.7%, P = 0.027) and 4 weeks (6.4% vs. 24.1%, P = 0.002). The difference in overall fissure healing between test cream and placebo was significant (P < 0.001) and test cream resulted in greater xerosis improvement (P < 0.001 and P = 0.002 at 2 and 4 weeks, respectively)., Conclusion: The activity of the test cream for treating feet fissures of people with diabetes was confirmed by an improvement in open fissure healing and xerosis. The cream was well tolerated., (© 2017 Diabetes UK.)

Objective: Biomechanical data from post mortem human subject (PMHS) experiments are used to derive human injury probability curves and develop injury criteria. This process has been used in previous and current automotive crashworthiness studies, Federal safety standards, and dummy design and development. Human bone strength decreases as the individuals reach their elderly age. Injury risk curves using the primary predictor variable (e.g., force) should therefore account for such strength reduction when the test data are collected from PMHS specimens of different ages (age at the time of death). This demographic variable is meant to be a surrogate for fracture, often representing bone strength as other parameters have not been routinely gathered in previous experiments. However, bone mineral densities (BMD) can be gathered from tested specimens (presented in this manuscript). The objective of this study is to investigate different approaches of accounting for BMD in the development of human injury risk curves., Methods: Using simulated underbody blast (UBB) loading experiments conducted with the PMHS lower leg-foot-ankle complexes, a comparison is made between the two methods: treating BMD as a covariate and pre-scaling test data based on BMD. Twelve PMHS lower leg-foot-ankle specimens were subjected to UBB loads. Calcaneus BMD was obtained from quantitative computed tomography (QCT) images. Fracture forces were recorded using a load cell. They were treated as uncensored data in the survival analysis model which used the Weibull distribution in both methods. The width of the normalized confidence interval (NCIS) was obtained using the mean and ± 95% confidence limit curves., Principal Results: The mean peak forces of 3.9kN and 8.6kN were associated with the 5% and 50% probability of injury for the covariate method of deriving the risk curve for the reference age of 45 years. The mean forces of 5.4 kN and 9.2kN were associated with the 5% and 50% probability of injury for the pre-scaled method. The NCIS magnitudes were greater in the covariate-based risk curves (0.52-1.00) than in the risk curves based on the pre-scaled method (0.24-0.66). The pre-scaling method resulted in a generally greater injury force and a tighter injury risk curve confidence interval. Although not directly applicable to the foot-ankle fractures, when compared with the use of spine BMD from QCT scans to pre-scale the force, the calcaneus BMD scaled data produced greater force at the same risk level in general., Conclusions: Pre-scaling the force data using BMD is an alternate, and likely a more accurate, method instead of using covariate to account for the age-related bone strength change in deriving risk curves from biomechanical experiments using PMHS. Because of the proximity of the calcaneus bone to the impacting load, it is suggested to use and determine the BMD of the foot-ankle bone in future UBB and other loading conditions to derive human injury probability curves for the foot-ankle complex., (Copyright © 2017.

Surgical management of soft-tissue defects of the forefoot and midfoot caused by trauma or diabetic complications can be challenging because locoregional tissue is insufficient to provide adequate flap. This deficiency necessitates higher-level amputations, such as Chopart or even transtibial amputation, resulting in far more debilitating functional outcomes than are seen with partial foot amputation. The purpose of this study was to examine the surgical outcomes after transmetatarsal amputation and a free-flap transfer to preserve foot length. This prospective case series was conducted from January 2011 to December 2015 at the Department of Plastic and Reconstructive Surgery at our institute. A total of 16 patients (11 men and 5 women) were enrolled in this study, all of whom were candidates for higher-level amputation because of inadequate soft-tissue coverage after debridement. Each patient underwent transmetatarsal amputation and reconstruction of the amputation stump using free-flap transfers to preserve foot length. Preoperative and postoperative data were collected to evaluate the postoperative outcomes. All 16 free-flap transfers were successful, with no major complications. In 2 cases, partial flap necrosis required additional skin grafting. The mean follow-up period was 24.3 months (range = 7-55 months). Flap coverage was stable, and all the patients were comfortable with their prostheses at long-term follow-up. Use of a free flap to reconstruct a transmetatarsal amputation stump provided stable coverage, preserved maximal foot length, and resulted in good functional outcomes.

The incidence of leprosy is decreasing worldwide and it is considered a rare disease in developed countries. In Spain, leprosy is mainly an imported disease with only few autochthonous cases seen. The diagnosis is difficult because of a low index of suspicion and the absence of visualisation of fast-acid bacilli in the lesions. Here, we report an autochthonous case of leprosy diagnosed after 4 years of evolution of skin lesions. Mechanical rupture of the biopsy helped finally to make the correct diagnosis of the disease.

Purpose: We report the clinical outcome after coverage for soft-tissue defect on the medial foot and ankle with an adipofascial fold-down flap based on the posterior tibial artery perforator branch proximal to the defect., Materials: Nine patients (five males and four females) with soft-tissue defects on the medial foot and ankle area underwent the procedure from March 2009 to May 2014. The average age of the patients was 54 years (range, 8-82). The pivot point of transposition of this flap is the posterior tibial artery perforator proximal to the defect. Therefore, the adiposal side of this flap was folded down to resurface the defect. The donor site was closed primarily with the preserved skin flap. The skin graft to the flap was delayed until the flap became mature. The difference between the circumferences of both ankles was measured., Results: All flaps survived and adequate soft-tissue coverage was obtained for the medial foot and ankle after the skin graft. Wearing normal footwear was possible for all patients because of thin coverage of the flaps. No secondary debulking procedure was performed for the patients. The difference between the circumferences of both sides of the ankle was not significant. The skin necrosis of the donor site was also managed conservatively and healed well., Conclusion: For the medial foot and ankle soft-tissue defect, the fold-down adipofascial flaps based on the posterior tibial artery perforator branch proximal to the defect could be a good option to cover it., (Copyright © 2016 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

A fracture of the os peroneum is a rare cause of ankle and foot pain and is often overlooked and not assumed. Only a few case reports have discussed the different etiologies, options for diagnosis, and therapeutic interventions for acute cases. We present a case of delayed diagnosis of an os peroneum fracture due to a distortion of the ankle that occurred during air sports. Initial diagnostic testing with magnetic resonance imaging demonstrated a rupture of the peroneus longus tendon with no pathologic abnormalities at the peroneus brevis tendon. During surgery, a combination of an os peroneum fracture and a peroneus brevis tendon split was found and was successfully treated with bone and tendon repair using a lasso stich technique.

Background: Intra-articular calcaneus fractures result in heel shortening, widening, varus malalignment, and loss of height. Little has been written regarding superior displacement of the calcaneal tuber, which warrants consideration as previous literature has demonstrated issues arising from a shortened triceps surae. We sought to determine the amount of tuber elevation seen in calcaneus fractures as compared to normal calcanei and propose 2 new measurements that aid in quantifying displacement and may aid in the surgical management of calcaneus fractures., Methods: Lateral radiographs of 220 normal calcanei were examined. Two novel measurements, the talo-tuber angle and talo-tuber distance, were used to establish normative data for calcaneal tuber positioning. Lateral radiographs of 50 calcaneus fractures treated operatively were examined and the same measurements were obtained before and after surgery to determine the amount of superior tuber elevation., Results: Normative data demonstrated a mean of 38.6 degrees (±SD = 4.3, range: 26.2-58.4) when using the talo-tuber angle and 54.5 mm (±SD = 7.3, range: 36.2-72.6) when using the talo-tuber distance in normal calcanei. Patients sustaining calcaneus fractures demonstrated a mean of 29.5 degrees (±SD = 5.9, range: 20-46.4) for the talo-tuber angle and 39.0 mm (±SD = 9.4, range: 24.0-62.9) for the talo-tuber distance. These values changed to a mean of 37 degrees (±SD = 5.2, range: 26.4-50) for the talo-tuber angle and 51.8 mm (±SD = 8.6, range: 33.2-75.7) for the talo-tuber distance after surgery. There was a statistically significant difference (P value < .01) for both talo-tuber angle and distance between normal and fractured calcanei. Inter- and intra-observer agreement was excellent., Conclusion: Superior displacement of the calcaneal tuber is a deformity seen in intra-articular calcaneus fractures that has been poorly described that warrants increased awareness and correction at the time of surgery. We propose 2 novel measurements with associated normative data that may aid surgeons in quantifying this deformity and assessing anatomic reduction., Level of Evidence: Level III, comparative study., (© The Author(s) 2016.)

The treatment of Zone 1 fractures of the 5th metatarsal base with >2mm of displacement remains controversial. We prospectively analyzed 29 patients with 5th metatarsal base fractures (Zone 1) during 2009-2014. Radiography was performed to assess the degree of fracture gap and metatarsal length. Patients with gaps of 2mm or less were treated conservatively using a short leg cast or splint (Group A), while patients with fracture gap >2mm were randomly assigned to one of two groups. Group B patients were managed with open reduction and internal fixation (ORIF), and Group C patients were placed in a short leg cast only. Visual analog scale (VAS) score and American orthopedic foot and ankle society (AOFAS) score were obtained at the initial consult and at the last follow-up after treatment; change of the 5th metatarsal length was also measured at the initial consult and after complete bony union. Our study demonstrated that radiographic union of all cases was observed with a significant decrease in VAS and AOFAS scores, regardless of the initial fracture gap and type of management. Additionally, there was no difference seen in final VAS scores for patients with longer metatarsals when compared to those in whom the metatarsals were unchanged or shortened., (Copyright © 2016 Elsevier Ltd.

Introduction: Foot and ankle impact injury is common in geriatric trauma and often leads to fracture of rearfoot, including calcaneus and talus. The objective of this study was to assess the influence of foot impact on the risk of calcaneus and talus fracture via finite element analysis., Methods: A three-dimensional finite element model of foot and ankle was constructed based on magnetic resonance images of a female aged 28. The foot sustained a 7-kg passive impact through a foot plate. The simulated impact velocities were from 2.0 to 7.0 m/s with 1.0 m/s interval., Results: At 5.0 m/s impact velocity, the maximum von Mises stress of the trabecular calcaneus and talus were 3.21MPa and 2.41MPa respectively, while that of the Tresca stress were 3.46MPa and 2.55MPa. About 94% and 84% of the trabecular calcaneus and talus exceeded the shear yielding stress, while 21.7% and 18.3% yielded the compressive stress. The peak stresses were distributed around the talocalcaneal articulation and the calcaneal tuberosity inferiorly, which corresponded to the common fracture sites., Conclusions: The prediction in this study showed that axial compressive impact at 5.0 m/s could produce considerable yielding of trabecular bone in both calcaneus and talus, dominantly by shear and compounded with compression that predispose the rearfoot in the risk of fracture. This study suggested the injury pattern and fracture mode of high energy trauma that provides insights in injury prevention and fracture management.

The first metatarsophalangeal joint and hallucal-sesamoid complex are critical structures in weightbearing and susceptible to several pathologies including turf toe, sesamoiditis, degenerative or inflammatory arthritides, infection, and avascular necrosis. This review article summarizes the complex anatomy of the region, covers common pathologies while clarifying terms such as turf toe and sesamoiditis, reviews imaging techniques, and discusses management., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

The etiology of skin integrity disorders of the lower extremities can be very diverse. In addition to common diagnoses such as venous ulcers with ischemic etiology, decubitus ulcers and diabetic foot syndrome, ulceration of a malignant etiology must also be considered. Malignant melanoma is one of the most dangerous forms of skin cancer and, although rare, may cause foot lesions. The most frequently encountered type of melanoma on acral parts of the limbs is the rare acral lentiginous variant, which only occurs in 2-10% of all melanoma types. Clinical manifestation ranges from cutaneous surface erosion to ulceration with surrounding hyperkeratosis, which can cause considerable differential diagnostic difficulties in the management of patients with non-healing foot wounds. This paper aims to present a clear case study of a Caucasian female with chronic leg ulceration that resulted in a final diagnosis of malignant acral lentiginous melanoma. Supplemental theoretical information regarding the diagnosis and treatment of malignant melanoma has also been included in the report. Malignant acral lentiginous melanoma is a rare cause of non-healing wounds, but it must be considered in cases with long-term healing complications. Precise diagnostic deliberation is crucial in the management and treatment of all chronic and long-term non-healing lesions, and appropriately performed biopsies are essential to determine whether malignancy is the primary cause.

We report an unanticipated medication effect resulting in near-complete wound healing in a patient after beginning tadalafil therapy of 20 mg thrice daily. This patient was treated for 50 years with state-of-the art acute and then chronic wound interventions after a traumatic farm machinery accident which resulted in a devascularised foot wound. This infection was both life- and limb-threatening. The patient had undergone multiple vascular and plastic surgeries and antimicrobial therapies in addition to hospitalisations for sepsis. Limb amputation was being considered, when his urologist placed him on daily phosphodiesterase-5 inhibitor therapy, prior to unrelated urologic surgery. Remarkably, his foot wound underwent near-complete resolution and has been stable for 2 years., (© 2015 The Authors.

Reasons for Performing Study: Recent studies indicate a high prevalence of fractures of the palmar processes (PP) of the distal phalanx in foals. However, information on the prevalence of such fractures in different breeds and the effect of predisposing factors, such as hoof conformation, is limited., Objectives: To examine the prevalence of distal phalanx PP fractures in foals and report the relationship of distal limb and hoof conformation with the prevalence of fracture., Study Design: Longitudinal study., Methods: Front hooves of 19 Thoroughbred, Quarter Horse and Arabian foals were examined. Digital radiographic and photographic images of the distal aspect of the forelimbs were taken at ∼2.5 month intervals. Five radiographic projections of each limb were as follows: lateromedial; horizontal beam dorsopalmar; dorso60°proximal-palmarodistal oblique; dorso60°proximo45°lateral-palmarodistomedial oblique; and dorso60°proximo45°medial-palmarodistolateral oblique. The relationship between measurements and the prevalence of fractures was assessed by 3-way ANOVA., Results: Fractures were found in 74% (n = 14) of the foals during the study period. The prevalences of lateral PP and medial PP fractures were not significantly different. Several hoof measurements were associated with PP fractures. Longer dorsal length of the distal phalanx was associated with medial PP fractures, while smaller lateral angle and shorter lateral palmar length were associated with a higher prevalence of lateral PP fractures., Conclusions: This study revealed a high prevalence of PP fractures in young foals, particularly in Thoroughbred foals. The hoof conformation may be one of the contributory factors to PP fractures in foals., (© 2014 EVJ Ltd.)

Introduction: Surgical management of calcaneus fractures is technically demanding and has a high risk of wound complications. These fractures are traditionally managed with splinting until swelling has subsided, which can take weeks and leaves the fracture fragments displaced. We describe a novel protocol for the management of displaced intraarticular calcaneus fractures that utilises a temporising external fixator and staged conversion to plate fixation through a sinus tarsi approach. The goal of this technique was to enable earlier treatment with open reduction and internal fixation, minimise the amount of manipulation required at the time of definitive fixation and reduce the wound complication rate seen with the traditional extensile approach., Methods: The records of patients with displaced calcaneus fractures from 2010-2014 were reviewed retrospectively. A total of nine patients with 10 calcaneus fractures were treated using this protocol. All patients underwent ankle-spanning medial external fixation within 48 hours after injury. Patients underwent conversion to open plate fixation through a sinus tarsi approach when skin turgor had returned to normal. Time to surgery, infection rate, wound complications, radiographic alignment, and time to radiographic union were recorded., Results: The average Bohler's angle improved from 13.2 (range -2 to 34) degrees preoperatively to 34.3 (range 26 to 42) degrees postoperatively. The average time from external fixation to conversion to internal fixation was 4.8 (range 3 to 7) days. There were no immediate post-surgical complications. The average time to weight-bearing was 8.5 weeks. The average time to radiographic union was 9.5 (range 8 to 12) weeks. There were no infections or wound complications at the time of last follow-up., Conclusion: Early temporising external fixation for the acute management of displaced calcaneus fractures is a safe and effective method to reduce and stabilise the foot and may decrease the time to definitive fixation. There were no complications related to the use of the external fixator in this series., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Background: Many rock climbers wear ill-fitting and excessively tight footwear during activity. However, there is insufficient evidence of the extent or harms of this practice., Objectives: To investigate footwear use in rock climbers with a focus on issues surrounding fit., Methods: A cross-sectional study with active rock climbers of over one year of experience completing a survey on their activity and footwear. Additionally, the authors quantified foot and shoe lengths and sizes alongside demographic data., Results: Ill-fitting and excessively tight footwear was found in 55 out of 56 rock climbers. Foot pain during activity was also commonplace in 91% of the climbers. A mean size reduction of almost 4 UK shoe sizes was found between the climbers' street shoe size and that of their climbing footwear using a calibrated foot/shoe ruler. There is an unfortunate association of climbers of higher abilities seeking a tighter shoe fit (p<0.001)., Conclusion: With the elucidation of footwear use amongst rock climbers, further investigation may aim to quantify its impact and seek a solution balancing climbing performance while mitigating foot injury., (Copyright © 2015 Elsevier Ltd.

Sports injuries of the midfoot and forefoot encompass a spectrum of osseous and soft tissue trauma. Magnetic resonance imaging serves as a primary or important supplementary diagnostic modality in evaluation of various injuries, most important of which include Lisfranc complex injury, stress fractures, and injury to the first metatarsophalangeal joint, aka "turf toe." Current technical advances in magnetic resonance and improved knowledge of regional anatomy enable thorough evaluation of the complex anatomic structures of the foot and facilitate accurate diagnosis in the setting of trauma.

Nowadays, despite improvements in safety rules and inspections in the metal industry, foundry workers are not free from burn accidents. Injuries caused by molten metals include burns secondary to molten iron, aluminium, zinc, copper, brass, bronze, manganese, lead and steel. Molten aluminium is one of the most common causative agents of burns (60%); however, only a few publications exist concerning injuries from molten aluminium. The main mechanisms of lesion from molten aluminium include direct contact of the molten metal with the skin or through safety apparel, or when the metal splash burns through the pants and rolls downward along the leg. Herein, we report three cases of deep dermal burns after 'soaking' the foot in liquid aluminium and its evolutive features. This paper aims to show our experience in the management of burns due to molten aluminium. We describe the current management principles and the key features of injury prevention., (Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.)

Background: Forklift-related crush injuries of the foot and ankle are relatively common in cities with shipping and construction industries. There is a paucity of literature on the incidence and sequelae of such injuries. We aimed to describe the incidence, patterns of injuries, sequelae, and morbidity associated with this type of injury., Methods: A retrospective review of all patients with forklift-related crush injuries of the foot and ankle for 4 years was conducted. Patients' demographics, mechanisms and patterns of injury, fracture type, compartment syndrome, number of reconstructive operations, operative details, length of hospital stay, medical leave, repeat evaluation in emergency room, and complications were recorded and analyzed., Results: There were 113 (2.17%) patients with forklift-related crush injuries out of 5209 patients seen in our institution for injuries of the foot and ankle. Crush injury from the wheels of the forklift truck was the most common mechanism at 71 (62.8%) patients. The forefoot was the most commonly injured region, followed by the midfoot, hindfoot, and ankle, with almost one-third (28.3%) of the patients having multiple injuries to the foot. Nine (8%) had open fractures, while 5 (4.4%) had compartment syndromes. Forty (35.4%) patients required hospitalization, and 35 (87.5%) of those hospitalized required operative intervention. Those who had surgery were more likely to have complications compared with those who did not require operative intervention (16 [45.7%] of 35 patients vs 7 [9%] of 78 patients; P < .05) and more likely to require longer medical leave (mean, 183 vs 30 days, P < .05)., Conclusion: Forklift-related crush injuries of the foot and ankle are increasingly common in industrialized cities. The forefoot is commonly affected with involvement of multiple regions. Up to one-third of affected patients required hospitalization and multiple operative interventions resulting in loss of productivity, income, and significant morbidity. The possibility of residual disabilities must be clearly defined to the patients and their employers to manage potential workplace limitations and long-term expectations., Level of Evidence: Level IV retrospective case series., (© The Author(s) 2015.)

This study reports the findings of 120 traumatic pad injuries in pet and military dogs. Most dogs (68%) presented with a laceration to a thoracic limb footpad, and one-third of dogs were middle-aged castrated males. Metacarpal pads were most commonly injured. Short-term complications were noted in 27% of dogs. No long-term complications were identified. No disability from pad injury was present at the completion of healing. Concurrent injuries to adjacent structures were uncommon and did not affect outcome. Dogs with full-thickness pad lacerations were at greater risk for major short-term complications compared to dogs with partial-thickness pad lacerations (odds ratio, 7.27; P = .001). Military working dogs with full-thickness pad lacerations were at greater risk for major short-term complications than pet dogs with a similar injury. When major complications developed in dogs with full-thickness pad injuries, time to final healing was significantly longer (by a median of 12 days). The partial-thickness pad lesions healed uneventfully regardless of whether they were bandaged, surgically repaired, or left to heal by second intention. Suture repair and bandaging of full-thickness lesions could not be shown to either decrease the risk for complications or improve healing. Future work should focus on establishing standards for footpad treatment to reduce complications.

In pus and wound samples collected from the right second toe of a 61-year-old woman with diabetes mellitus (DM), gram-negative diplococci bacterium was observed. However, the bacterium could not be identified by conventional microbiological methods and mass spectrometry. In the partial 16S rRNA gene sequence analysis, the bacterium showed a 100% identity match with GenBank sequence FJ0763637.1 (Neisseria skkuensis). N. skkuensis, SMC-A9199 strain, was reported as a novel species in 2010 based on its phenotypic characteristics and the 16S rRNA gene sequence, which was isolated from the blood and wound pus of a DM patient with a foot ulcer. The second reported N. skkuensis was identified from the blood cultures of a patient with endocarditis. To the best of our knowledge, this is only the third report of N. skkuensis., (© 2015 by the Association of Clinical Scientists, Inc.)

Background: Neonatal surgical injury triggers developmentally regulated long-term changes that include enhanced hyperalgesia and spinal microglial reactivity after reinjury. To further evaluate priming of response by neonatal hindpaw incision, the authors investigated the functional role of spinal microglial p38 mitogen-activated protein kinase after reincision in adult rodents., Methods: Plantar hindpaw incision was performed in anesthetized adult rats, with or without previous incision on postnatal day 3. Numbers and distribution of phosphorylated-p38 (1, 3, 24 h) and phosphorylated extracellular signal-regulated kinase (15 min, 24 h) immunoreactive cells in the lumbar dorsal horn were compared after adult or neonatal plus adult incision. Withdrawal thresholds evaluated reversal of incision-induced hyperalgesia by p38 inhibition with intrathecal SB203850., Results: Neonatal injury significantly increased phosphorylated-p38 expression 3 h after adult incision (55 ± 4 vs. 35 ± 4 cells per section, mean ± SEM, n = 6 to 7, P < 0.01). Increased expression was restricted to microglia, maintained across lumbar segments, and also apparent at 1 and 24 h. Preincision intrathecal SB203850 prevented the enhanced mechanical hyperalgesia in adults with previous neonatal injury and was effective at a lower dose (0.2 vs. 1 mg/kg, n = 8, P < 0.05) and for a longer duration (10 vs. 3 days). Lumbar neuronal phosphorylated extracellular signal-regulated kinase expression reflected the distribution of hindpaw primary afferents, but was not significantly altered by previous incision., Conclusions: Neonatal incision primes spinal neuroglial signaling, and reincision in adult rats unmasks centrally mediated increases in functional microglial reactivity and persistent hyperalgesia. After early life injury, p38 inhibitors may have specific benefit as part of multimodal analgesic regimes to reduce the risk of persistent postsurgical pain.

Introduction: Reconstruction of complex injuries involving bone and soft-tissue in foot remains a tough challenge for surgeons. The free fibular flap is a popular flap for treating these composite defects. However, complications caused by microvascular anastomoses are not uncommon. Herein, we designed a pedicled fibular flap elevated in the ipsilateral leg for reconstruction of multiple defects in foot., Methods: From July 2005 to April 2013, four patients with composite defects in foot were treated by pedicled fibular flaps. The defects were located in the first metatarsal bone and medial cuneiform bone in two patients, in the fourth metatarsal bone in one patient, and in the second to fourth metatarsal bones in one patient. The size of soft-tissue defects ranged from 10×7 cm to 15×7 cm, and the length of bone defects ranged from 6 to 8 cm., Results: The length of fibular grafts ranged from 7 to 8.5 cm, and the size of skin flaps ranged from 11×8 cm to 16×8 cm. All flaps survived completely. Complications occurred in two patients. One suffered moderate venous congestion and the flap survived without intervention. The other one sustained re-infection. Debridement was performed and the wound healed uneventfully. Follow-up ranged from 8 to 32 months. Bone union occurred at an average of 12 weeks, and the skin flaps showed good cosmetic results. No serous donor-site complications occurred., Conclusion: The pedicled fibular flap transfer could avoid anastomosis complications and preserve healthy limb. It is a good option for reconstruction of complex defects in foot., (Copyright © 2014. Published by Elsevier Ltd.)

Antiphospholipid syndrome and systemic erythematosus have been associated with metatarsal stress fractures. Stress fractures of the Lisfranc joint complex are uncommon injuries but have been reported to occur most frequently in ballet dancers. We present a case of an avulsion fracture of the Lisfranc joint complex that occurred spontaneously. We have reviewed the association between systemic conditions and metatarsal fractures and proposed a series of hypothetical pathological events that may have contributed to this unusual injury.

Background: There is a range of different types of tears and pathology of the peroneal tendons. One of the least common types is the tear of the peroneus longus associated with fracture, enlargement, or entrapment at the cuboid tunnel of the os peroneum. The purpose of this study was to evaluate the pathologic patterns of these uncommon peroneal tendon tears, to review the treatment, and to report the patient outcomes following treatment with excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis., Methods: A 5-year retrospective review of all patients with peroneal tendon tears identified 12 patients operatively treated for peroneus longus tendon tears with associated pathology of the os peroneum, and in whom there was a viable peroneus brevis. All patients were treated with an operative procedure consisting of excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. Mean age was 51.5 (range, 33 to 73) years, including 7 males and 5 females. Operative and radiographic records were reviewed to characterize the nature of the peroneus longus tears and associated pathology. Preoperative and postoperative AOFAS hindfoot, SF-36 questionnaires, and Visual Analog Scale (VAS) pain scores were compiled and patient records were reviewed for complications. Mean follow-up after surgery was 63.3 (range, 12 to 114) months., Results: All of the patients had an os peroneum associated with a complex, irreparable tear of the peroneus longus tendon. The peroneus longus was typically enlarged, fibrotic, and adhered to the surrounding tissues. In 8 patients, the peroneus longus tendon tear was associated with a fracture of the os peroneum, and in 4 patients with an enlarged and entrapped os peroneum which prevented movement at the cuboid tunnel. Of the 12 patients, 9 had partial tears of the peroneus brevis, which were treated with debridement and suture repair. AOFAS hindfoot scores increased from a preoperative mean of 61 (range, 46 to 75) to a postoperative mean of 91.7 (range, 60 to 100). Mean preoperative SF-36 Physical Component Scores (PCS) increased from 36 to 52 postoperatively. Mean VAS pain scores decreased from a preoperative mean of 6.3 (range, 4 to 8) to a postoperative mean of 1.0 (range, 0 to 4). Complications included 2 patients with sural neuritis and 3 with superficial delayed wound healing successfully treated nonoperatively., Conclusion: Tears of the distal peroneus longus tendon, which are much less commonly reported than tears of the peroneus brevis, can be associated with pathology of the os peroneum. Excision of the os peroneum, tendon debridement, and tenodesis of the longus to brevis was an effective surgical technique., Level of Evidence: Level IV, case series.

Background: New advances in regenerative surgery may increase the potential for rehabilitation in the injured foot., Objectives: A clinical prospective observational study was carried out to assess the effectiveness of lipofilling to improve the functional recovery of the injured foot., Methods: Four patients with anatomical-functional impairment following repair of post-traumatic soft tissue loss of the foot were involved in the study. All of the patients complained of pain in the repaired plantar weight bearing area, skin instability, recurrent ulcerations and were walking on crutches. A combined plastic surgery and technical orthopaedic assessment identified the plantar areas requiring anatomical changes for load redistribution. Two selective sequential lipofillings with a 12 weeks' time interval were performed. Manufacturing of custom-made plantar insoles and/or shoes followed each surgical procedure., Results: After the treatment all of the patients progressively recovered both a better plantar load distribution and a local soft tissue stability, referred the remission of chronic pain and discontinued the use of crutches., Conclusion: Lipofilling proved to be an effective and versatile surgical technique for both reconstructive and regenerative purposes. The interaction between the Plastic Surgery staff and the Orthopaedic Technician outlined a successful multidisciplinary approach model for the rehabilitation of the injured foot., (Copyright © 2014 The Authors.

Mortality due to electrical injury in wildlife may occur in the form of lightning strike or power line contact. Evidence of electrical contact may be grossly obvious, with extensive singeing, curling, and blackening of feathers, fur, or skin. Occasionally, changes may be subtle, owing to lower current or reduced conductivity, making a definitive diagnosis of electrocution more difficult. We describe the use of an alternate light source in the examination of cases of lightning strike and power line contact in wildlife, and the enhanced detection of changes due to electrical currents in the hair and feathers of affected animals. Subtle changes in the wing feathers of 12 snow geese and 1 wolf that were struck by separate lightning events were made obvious by the use of an alternate light source. Similarly, this technique can be used to strengthen the evidence for power line exposure in birds., (Published by Elsevier Ireland Ltd.)
