BACKGROUND AND AIM: The toe skin temperature in vascular patients can be low, making reliable toe pressure measurements difficult to obtain. The aim of this study was to evaluate the effect of heating on the toe pressure measurements. MATERIALS AND METHODS: A total of 86 legs were examined. Brachial pressure and toe pressure were measured at rest in a supine position using a laser Doppler device that also measured skin temperature. After heating the toes for 5 min with a heating pad, we re-measured the toe pressure...

BACKGROUND: Orthotic insoles that are made of foam material often have less breathability and thus cause discomfort to the wearer. Given that a sandwich structure offers better porosity and breathability that would improve comfort, the impact of custom-made insoles made with three-dimensional spacer fabric is studied. OBJECTIVES: To examine the biomechanical effects and subjective comfort of spacer-fabric insoles during walking. STUDY DESIGN: Repeated measures...

BACKGROUND: Congenital bilateral hallux valgus with associated absence or fusion of the interphalangeal joint is a classic diagnostic feature of fibrodysplasia ossificans progressiva (FOP), a human genetic disease of extra-skeletal bone formation caused in nearly all cases by a gain-of-function mutation in Activin A Receptor I/Activin-like Kinase 2 (ACVR1/ALK2), which encodes a bone morphogenetic protein (BMP) Type 1 receptor. This toe malformation prompts the suspicion of FOP even before the appearance of extra-skeletal bone...

REVIEW
Greg A J Robertson, Alexander M Wood
Stress fractures in sport are becoming increasing more common, comprising up to 10% of all of sporting injuries. Around 90% of such injuries are located in the lower limb. This articles aims to define the optimal management of lower limb stress fractures in the athlete, with a view to maximise return rates and minimise return times to sport. Treatment planning of this condition is specific to the location of the injury. However, there remains a clear division of stress fractures by "high" and "low" risk. "Low risk" stress fractures are those with a low probability of fracture propagation, delayed union, or non-union, and so can be managed reliably with rest and exercise limitation...

Real-time detection of multiple stance events, more specifically initial contact (IC), foot flat (FF), heel off (HO), and toe off (TO), could greatly benefit neurorobotic (NR) and neuroprosthetic (NP) control. Three real-time threshold-based algorithms have been developed, detecting the aforementioned events based on kinematic data in combination with a biomechanical model. Data from seven subjects walking at three speeds on an instrumented treadmill were used to validate the presented algorithms, accumulating to a total of 558 steps...

BACKGROUND: Several studies have demonstrated ultrasound (US) is superior to traditional landmark (LM)-based techniques for large and medium joint aspiration; however, no studies of sufficient size have evaluated these interventions in the smaller toe joints. The purpose of this study was to determine if US provides an advantage over LM for successful first-pass aspiration of first metatarsophalangeal joint (1st MTPJ) effusions. METHODS: A cross-over, cadaveric trial evaluating the interventions of US and LM...

OBJECTIVE: To compare overall physical function, including gait speed and peripheral nerve function, between diabetic chronic kidney disease (CKD) patients and nondiabetic CKD patients and to investigate the association between gait speed and peripheral nerve function in CKD patients. METHODS: Sixty adult CKD patients (35 with and 25 without diabetes), who received maintenance hemodialysis (HD), were included in this study. Demographic data, past medical history, current medical condition and functional data-usual gait speed, vibration perception threshold for the index finger (VPT-F) and the great toe (VPT-T), activity of daily living (ADL) difficulty, and peripheral neuropathy (PN) along with the degree of its severity-were collected and compared between the two groups...

The formation of lamellar bone in the soft tissues, where bone normally does not exist, is called myositis ossificans. However, it would be more accurate to describe as myositis ossificans the involvement of skeletal muscles and as ectopic or heterotopic ossification the involvement of soft tissues in general. The lesion is subdivided in genetic and non-genetic or acquired types. Myositis or fibrodysplasia ossificans progressiva is a debilitating rare genetic disorder. Clinical suspicion of the disease in the newborn on the basis of malformed great toes may lead to early clinical diagnosis, confirmatory diagnostic genetic testing and avoidance of iatrogenic harmful procedures...

This report presents a case of stenosing tenosynovitis of the flexor hallucis longus tendon associated with the plantar capsular accessory ossicle at the interphalangeal joint of the great toe, which was confirmed by intraoperative observation and was successfully treated with surgical resection of the ossicle. As the plantar capsular accessory ossicle was not visible radiographically due to the lack of ossification, ultrasonography was helpful for diagnosing this disorder.

BACKGROUND: We analyzed clinical and radiologic examination of intra-articular fracture of the proximal phalanx of great toe accompanied by valgus deformity associated with sports activities. Therefore, we assessed valgus deformity of great toe at fracture side and contralateral side by simple radiograph in order to confirm the causal relation of fracture and deformity. METHODS: A retrospective study was conducted on 23 cases, between January 2000 and August 2014, which showed an intra-articular fracture of proximal phalanx which was diagnosed after visiting our hospital for valgus deformity of great toe as a chief complaint...

Superficial acral fibromyxoma (SAF) is a slow growing soft tissue tumor that mainly appears in the acral areas. Here, we report a case of a SAF with distinctive immunophenotype charachteristics. An 18-year-old female was referred to our clinic with the complaint of painless subungual nodule of great toe for a few months. The diagnosis of SAF was made according to histopathology and immunohistochemical (IHC) study, however, the IHC assessment showed positive staining with vimentin, focal reaction with smooth muscle actin, negative reaction with CD34, and positive staining pattern with CD99...

Superficial acral fibromyxoma is a rare clinical entity, first described in 2001. It is a soft tissue tumor with a predilection for the fingers and toes. Since it was described, few cases have been reported. We present a case of an 88-year-old male with a history of a slow-growing lump in his left great toe after local trauma. The patient underwent surgical excision, and pathologic analysis revealed the diagnosis of superficial acral fibromyxoma. Although an unusual diagnosis, surgeons should be aware of this myxoid tumor, which requires complete surgical excision and short-term follow-up to detect recurrence...

Open physeal fractures of the distal phalanx of the hallux are the lesser described counterpart to the same fracture of the finger, known by its eponym as a "Seymour fracture". Displaced Salter-Harris phalangeal fractures present with a concomitant nailbed or soft tissue injury. Often these fractures occur in the summer months when open-toe footwear can be worn, however, they may occur indoors as well. Frequently, the injury results from direct axial load of the toe, or "stubbing", which causes the fracture and associated soft tissue injury...

David R Carrier, Christopher Cunningham
In contrast to most other primates, great apes have feet in which the heel supports body weight during standing, walking and running. One possible advantage of this plantigrade foot posture is that it may enhance fighting performance by increasing the ability to apply free moments (i.e. force couples) to the ground. We tested this possibility by measuring performance of human subjects when performing from plantigrade and digitigrade (standing on the ball of the foot and toes) postures. We found that plantigrade posture substantially increased the capacity to apply free moments to the ground and to perform a variety of behaviors that are likely to be important to fighting performance in great apes...

Kun Zheng, Hongming Zhuang
A 3-year-old boy with history of neuroblastoma underwent I-MIBG scan. The whole-body images showed relatively normal tracer distribution except for mild activity in the right foot, which was located in the first metatarsal on SPECT/CT images. The subsequent MRI scan of the right foot showed infiltration of the metatarsal of the right first toe. The findings were consistent with solitary acrometastasis of neuroblastoma to the great toe.

227 Background: Knowledge of immune-system regulation led to the discovery of immune checkpoints molecules, which have demonstrated anti-tumor activity across various malignancies. These advances represent a new set of challenges for clinicians, including non-oncologists treating the cancer patient, who must develop a working knowledge of the mode of action of these agents, their unique response kinetics, and how to diagnose and effectively manage their toxicities. Nivolumab is a monoclonal immune checkpoint antibody that binds to the PD-1 receptor on T-cells, blocking PD-1 pathway-mediated anti-tumor immune response inhibition...

PURPOSE OF REVIEW: Injuries to the great toe are common in athletes. While most are managed nonoperatively and allow return to sports activity, some great toe injuries are highly problematic and can impact function. The purpose of this review is to highlight several specific injuries and disease processes involving the hallux and to detail current recommendations and management options in order to help raise suspicion for injuries that can result in long-term dysfunction. RECENT FINDINGS: Toe injuries have been found to represent nearly 10% of injuries presenting to fracture clinics...

REVIEW
Michael P Gaspar, Danielle M Wilbur, Peter J Stern, Randall W Culp
Autograft tendon harvested from the long toe extensors are of great utility as intercalary grafts in upper extremity reconstruction. However, standard full-length harvest is complicated by the presence of extensor retinacula and multiple juncturae between adjacent extensors, which often necessitate extensive dissection, increasing the potential for morbidity. We describe a modified technique for partial harvest of the long toe extensors, which is performed entirely proximal to the superior extensor retinaculum...

BACKGROUND: Hallux rigidus can be treated using several different methods and the best treatment option depends on the severity of degenerative changes of the metatarsophalangeal (MTP) joint. However, the ideal operative option for advanced hallux rigidus remains debatable. This prospective study was performed to evaluate the intermediate-term clinical outcomes of distal metatarsal osteotomy used as a joint-preserving method for the treatment of advanced hallux rigidus. METHODS: Forty-two cases (39 patients) were followed for more than 3 years after distal metatarsal dorsiflexion osteotomy for advanced hallux rigidus of grade III-IV...
