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...

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...

Osteoid osteoma (OO) is a benign tumor that it is not generally seen in the foot and even less frequently in the phalanx (2-4%). The diagnosis when its location is intra-articular is a challenge and often delayed because the symptoms mimic a real arthritis. We report a clinical case involving a 16-year-old male patient who complained of persistent pain of the interphalangeal joint (IPJ) of the left hallux. A juxta-articular OO of the condyle of the proximal phalanx was identified. The patient underwent surgery that included tumor removal preserving the articular cartilage...

Digit sucking is common nonnutritive sucking habit in childhood. However it is unusual to find toe sucking habit in children. We report a case of a seven-year-old child sucking great toe of the left foot. The child was referred by her paediatrician for dental evaluation due to her complaint of recurrent episodes of pyrexia. A dental evaluation was warranted as no particular system contributed to such recurrent episodes of fever in this child. Although dental examination did not reveal any cause for recurrent episodes of pyrexia, as a part of routine history taking we discovered that this child indulges frequently in sucking the great toe of her left foot since infancy...

Objective: Toe-brachial index (TBI) is usually measured in the great toe (TBI-1). However, this is not always possible. To determine the usefulness of TBI measurement in the second toe (TBI-2), we examined the relation between systolic pressure in the second toe (toe pressure [TP-2]) and that in the great toe (TP-1) and evaluated the association between TBI and ankle-brachial index (ABI). Materials and Methods: We retrospectively analyzed patients who underwent a series of measurements of TBI-2, TBI-1, and ABI using an automatic oscillometric device at Kawasaki Medical School Hospital, Japan in 2012...

Subungual osteochondroma is a relatively uncommon benign bone tumor affecting mostly children and young adults, and is a major source of pain and nail deformity. Treatment consists of marginal excision and meticulous wound closure. In this report, we present three cases of subungual osteochondroma arising from the dorsal aspect of distal phalanx of the great toe, which were managed by marginal excision with preservation of nail apparatus under digital block anesthesia with the use of a ring tourniquet. We emphasize on the use of ring tourniquet made by glove's finger and the technique of preserving the nail apparatus to prevent nail deformity...

Fibrodysplasia ossificans progressiva is a rare disorder of heterotopic ossification. Procedures like biopsy and surgery are known to be aggravating factors in promoting heterotopic ossification Clues to clinical diagnosis may therefore be a great advantage to treating orthopedician. Valgus deformity of great toe is an important diagnostic clue for treating physicians and thus aids in preventing the clinicians from subjecting the patients to unnecessary invasive and traumatic procedures. Hence clinical clues to early diagnosis are important in establishing the correct diagnosis and directing future management...

The purpose of this study was to determine the installation of the backstroke start device reduces 15-m time. Thirteen college swimmers participated in this study. The aerial start and underwater motions were recorded with two digital video cameras. The center of mass (CM) of the swimmer, angular displacements and velocities of the shoulder, hip and knee joints were calculated. As an indicator of performance, the 5- and 15-m times were measured. The 5- and 15-m times in the backstroke start device condition were significantly shorter than in the non-backstroke start device condition...
