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...

Noonan syndrome (NS) is an autosomal dominant trait characterized by genotypic and phenotypic variability. It belongs to the Ras/MAPK pathway disorders collectively named Rasopathies or neurocardiofaciocutaneous syndromes. Phenotype is characterized by short stature, congenital heart defects, facial dysmorphisms, skeletal and ectodermal anomalies, cryptorchidism, mild to moderate developmental delay/learning disability, and tumor predisposition. Short stature and skeletal dysmorphisms are almost constant and several studies hypothesized a role for the RAS pathway in regulating bone metabolism...

Eichi Itadera, Takahiro Yamazaki
We developed a new internal fixation method for extra-articular fractures at the base of the proximal phalanx using a headless compression screw to achieve rigid fracture fixation through a relatively easy technique. With the metacarpophalangeal joint of the involved finger flexed, a smooth guide-pin is inserted into the intramedullary canal of the proximal phalanx through the metacarpal head and metacarpophalangeal joint. Insertion tunnels are made over the guide-pin using a cannulated drill. Then, a headless cannulated screw is placed into the proximal phalanx...

BACKGROUND: Internal fixation modalities of unstable (>50 percent articular involvement) middle phalangeal volar lip fracture-dislocations include interfragmentary screw and volar buttress plating. This study investigates the mechanical properties (yield strength, ultimate tensile strength, and stiffness) of interfragmentary screw (IS), simple buttress plating (BP) and buttress plating with subchondral screw (BP+S). METHODS: Fifteen cadaveric digits (5 index, 5 middle, and 5 ring) were prepared by excising its skin envelope and flexor tendons while preserving the structures around the proximal interphalangeal joint...

Pterosaurs are extinct flying reptiles, the first vertebrates to achieve powered flight. Our understanding of the evolutionary transition between basal, predominantly long-tailed forms to derived short-tailed pterodactyloids remained poor until the discovery of Wukongopterus and Darwinopterus in western Liaoning, China. In this paper we report on a new genus and species, Douzhanopterus zhengi, that has a reduced tail, 173% the length of the humerus, and a reduced fifth pedal digit, whose first phalange is ca...

Injuries to the hand during military combat operations, particularly from improvised explosive devices (IEDs) have a significant impact on form, function, mental health and future employment but remain underreported amidst the life and limb-threatening emergencies that garner more attention. An understanding the patterns of hand injuries encountered from IEDs is crucial to optimizing reconstruction and rehabilitation. The aim of this study was to re-evaluate hand injury sustained from IED in order to understand the clinical burden for reconstruction and direct the focus for future hand protection...

REVIEW
Franklin Chen, David M Kalainov
PURPOSE OF REVIEW: Phalangeal fractures, dislocations, and fracture-dislocations in the hand are common injuries. We review the current literature on the diagnosis and treatment of these injuries in the athlete. An understanding of the anatomy and its relationship to the mechanism of injury may help to direct appropriate management. Return to play remains an important concern to the patient-athlete. RECENT FINDINGS: Findings from recently published articles reinforce previously established treatment methods in the management of finger phalangeal fractures, dislocations, and fracture-dislocations...

Intraosseous epidermoid cysts are exceedingly rare. Known as pseudotumors, not true neoplasms, intraosseous epidermoid cysts usually involve the phalanges, the skull, and the toes. Intraosseous epidermoid cysts typically present as destructive osteolytic lesions on X-ray, mimicking malignant bone tumors. Here, we present two cases of an intraosseous epidermoid cyst in the distal phalanx treated with curettage and synthetic bone graft, followed by a review of the relevant literature. In both cases, the patient presented with a painful enlargement of the fingertip following a minor trauma...

Diplopodia, being a rare congenital disorder, is infrequently discussed in published texts. Most reported cases have accounted the involvement of duplicated preaxial digits with other associated organ system and physical deformities. Here, we present an unusual case of isolated diplopodia involving postaxial toes in a child with no other organ and physical abnormalities. Radiological studies revealed a set of 10-digit-duplicated foot over the lateral aspect of the native foot, complete with phalanges and its corresponding metatarsals as well as tarsals, supplied by an anomalous posterior branch of the popliteal artery...

: Intraosseous epidermal inclusion cysts (IEpC) are benign bone tumors that often present in the phalanges of the fingers, but rarely are seen in the lower extremity. These tumors often present following surgery, and have a similar clinical and radiographic presentation to osteomyelitis. The lack of defining characteristics makes preoperative diagnosis of these tumors very difficult. It is crucial to differentiate these tumors from malignant lesions with similar presentation. This case study presents our treatment of this osseous tumor and reviews the available literature describing this condition...

Inhibitory GABAergic and glycinergic neurotransmission in the spinal cord play a central role in the regulation of neuronal excitability, by maintaining a balance with the glutamate-mediated excitatory transmission. Glutamatergic agonists infusion in the spinal cord induce motor neuron death by excitotoxicity, leading to motor deficits and paralysis, but little is known on the effect of the blockade of inhibitory transmission. In this work we studied the effects of GABAergic and glycinergic blockade, by means of microdialysis perfusion (acute administration) and osmotic minipumps infusion (chronic administration) of GABA and glycine receptors antagonists directly in the lumbar spinal cord...

This paper focuses on design, fabrication and characterization of a biomimetic, compact, low-cost and lightweight 3D printed humanoid hand (TCP Hand) that is actuated by twisted and coiled polymeric (TCP) artificial muscles. The TCP muscles were recently introduced and provided unprecedented strain, mechanical work, and lifecycle (Haines et al 2014 Science 343 868-72). The five-fingered humanoid hand is under-actuated and has 16 degrees of freedom (DOF) in total (15 for fingers and 1 at the palm). In the under-actuated hand designs, a single actuator provides coupled motions at the phalanges of each finger...

Painful degenerative diseases of the second metatarsophalangeal joint are frequently progressive and difficult to treat. Surgical options for the degenerated second metatarsophalangeal joint include joint debridement and synovectomy, drilling and microfracture, core decompression, dorsal closing-wedge metatarsal osteotomies, joint arthroplasty (implant or interpositional), elevation of the depressed articular fragment and bone graft, distraction arthroplasty, osteochondral plug transplantation, osteochondral distal metatarsal allograft reconstruction, and resection arthroplasty (phalangeal base or metatarsal head)...

Deep hand burns usually lead to joint and tendon exposure. A simple skin graft is insufficient to achieve healing. Soft tissue reconstruction represents a surgical challenge that ranges from the simplest to the most complex flaps. In some areas, microsurgery is not technically possible. Choice is then limited to pedicled distant flaps such as the abdominal wall flap-graft. We report a case of an acute burned hand with exposure of metacarpophalangeal joints from the second to the fourth radius as well as proximal inter phalangeal joints from the second to the fifth radius and extensor tendons, treated in the burns and wound care unit of the Sylvanus Olympio Teaching Hospital in Lomé...

Sanjay Naran, Joseph E Imbriglia
Background: A case is discussed in which a young girl was born with symbrachydactyly of multiple digits in whom nonvascularized proximal toe phalanges were transferred to the aphalangic digits at the age of four. At 39 years of age, she presented incidentally to our clinic and was observed to have a very functional hand with mobile metacarpophalangeal joints in all reconstructed digits. Methods: We present a case report which is discussed in the context of long-term follow-up, and phalangeal growth in the absence of distraction, and a review of the current literature in regards to outcomes for this modality of treatment...

WHAT IS KNOWN AND OBJECTIVE: Drug-induced nephrotoxicity is potentially lethal. When sodium aescinate is given to surgical inpatients to treat postoperative inflammation and oedema, adverse drug reactions and drug-drug interactions must be closely monitored. CASE DESCRIPTION: We report a case of a 58-year-old man with phalangeal fractures who suffered from acute kidney injury that was most likely induced by the drug interaction between sodium aescinate and ginkgo biloba extract due to the protein-binding and metabolic characteristics of these drugs...

A swan neck deformity (SND) can be well tolerated for a long time, until the appearance of a disabling "snapping finger". In its most advanced condition, the other hand is needed to initiate finger flexion. We propose a technique of extra-articular, subcutaneous ligament reconstruction with an "inverted king post-truss" configuration use in roofs and to reinforce railway bridges. An artificial ligament (MaxBraid™ polyethylene surgical suture, 5 metric, Biomet) makes a figure of eight between transosseous tunnels in the proximal and middle phalanges, crossing over top of the A3 pulley...

Foot length has been shown to be a reliable dimension for estimation of stature. However, phalanges of the foot are very small bones and their length may not be proportional to person's stature. Thus, we hypothesized that foot length measured excluding the phalanges, the truncated foot length, may be more reliable in stature estimation than full foot length. This study, therefore, aimed at comparing the accuracy of the regression equations derived from the truncated foot length and the full foot length. The study recruited a sample of 32 young adults (16 males and 16 females) aged from 20 to 35 years...
