Yanchun Gao, Qiyang Wang, Hongyi Zhu, Zhengyu Xu
The optimal timing for surgical stabilization after open fractures of proximal and middle phalangeal shaft remained unclear. Total 147 patients with single open fracture in proximal or middle phalangeal shaft (arrived within 8 hours) who received K-wire fixation from June 2012 to June 2015 were included for analysis. The timing for surgical stabilization of fractures (immediate or delayed) was decided according to the surgeons' preferences. The Michigan hand outcomes questionnaire (MHQ) scores, grip strength and total active motion (TAM) one year after the initial surgery were similar between the two groups...

BACKGROUND: Surgical planning of corrective osteotomies is traditionally based on conventional radiographs and clinical findings. In the past 10 years, 3-dimensional (3D) preoperative planning approaches with patient-specific guides have been developed. However, the application of this technology to posttraumatic deformities of the metacarpals and phalangeal bones has not yet been investigated. Our goal was to evaluate the feasibility of the surgical application to the latter and to evaluate the extent and precision of correction...

INTRODUCTION: Ellis-van Creveld (EVC) syndrome is one of the rarest ciliopathy syndromes. It is caused by mutations of the EVC and EVC2 genes which encode the EVC proteins present in the basal body of the primary cilium. PRESENTATION OF CASES: We report on a Saudi family with two affected children. Gene analysis revealed a homozygous c.2T >A in exon 1 of the EVC gene. The most interesting finding in our patients was the wide - spread cone-shaped epiphyses in the hands and feet...

Copy number variations (CNVs) often include noncoding sequences and putative enhancers, but how these rearrangements induce disease is poorly understood. Here we investigate CNVs involving the regulatory landscape of IHH (encoding Indian hedgehog), which cause multiple, highly localized phenotypes including craniosynostosis and synpolydactyly. We show through transgenic reporter and genome-editing studies in mice that Ihh is regulated by a constellation of at least nine enhancers with individual tissue specificities in the digit anlagen, growth plates, skull sutures and fingertips...

The ratio of the lengths of the second and fourth digits (2D:4D) has been described as reflecting endogenous prenatal androgen exposure. In general, 2D:4D is lower in men than in women and has potential as a biomarker or predictor for various diseases, athletic ability, and academic performance. Dupuytren disease has digital flexion contractures and is known to predominate in men, but the pathogenesis of the disease remains unclear. To clarify the relationships between Dupuytren disease and endogenous androgens, we performed a retrospective analysis of hand radiographs to investigate 2D:4D in Dupuytren disease...

Dong Hyun Kim, Si-Hwan Heo, Hyung-Soon Park
For the rehabilitation and assistance of the hand functions, wearable devices have been developed, and the interest in tendon driven mechanisms have especially increased since it allows light weight and compact design. The tendon driven hand rehabilitation devices provides grasping force via exo-tendons routed on the dorsal and palmar sides of the hand pulled by remotely located actuators. However, most of the devices were not able to provide natural joint extension sequence of the finger and showed hyperextension of finger joints because the tendons for extension were fixed at the fingertip, concentrating the torque at the distal interphalangeal joint...

Commercially available prostheses do not meet patients' expectations regarding dimensions, shape and aesthetic reasons. This paper presents the design of an anthropomorphic and anthropometric prosthesis based on dimensions and shape extracted from a digitized radiograph of the healthy hand of the patient. The mobility of the hand is guaranteed by making a design of phalanges, joints, ligaments and tendons, as closest as possible to a real hand. The kinematic model is presented and validated. A proposal of the actuation system is also described...

BACKGROUND: Erythema palmare hereditarium (EPH), also known as Lane's disease, is a rare, benign condition presenting as persistent erythema involving the palms. EPH can appear at birth or later in life and usually in at least two members of the same family, although a sporadic case has been reported. METHODS: We report five cases of EPH and offer a review of the current literature. The first and second cases are twin boys presenting with erythema mainly on the thenar and hypothenar eminences and on the phalanges that appeared 8 months after birth...

Acrodysostosis is characterized by distinctive facial features and severe brachydactyly. Mutations in PRKAR1A or PDE4D are known to be responsible for this disease. Cases of hormonal resistance have been reported, particularly in patients with PRKAR1A mutations. The physical characteristics and endocrine function of pseudohypoparathyroidism type Ia is known to resemble acrodysostosis. We report the case of a 4-yr-old patient with a PRKAR1A mutation. He had characteristic facies with an upturned nose and cone-shaped epiphyses of most phalanges...

Fotios Alexandros Karakostis, Carlos Lorenzo, Konstantinos Moraitis
In previous studies, the anatomy of proximal hand phalanges has been described and techniques of anatomical allocation have been developed. However, these rely on the observation of small phalangeal traits without providing a multivariate analysis of morphological variation. In bioarchaeological contexts, the form of these distinctive traits is often not clear and the use of alternative supplementary methods is vital. This study aims to conduct a multivariate analysis of proximal phalanges and introduce a new methodology of ray allocation for isolated proximal phalanges...

Emergency arthroplasty of the metacarpophalangeal joint (MCPJ) remains a valuable treatment option in patients with MCPJ destruction but may raise challenges in the event of substantial metacarpal and/or phalangeal bone defects. We report three cases ofMCPJdestruction with bone defects at the proximal first phalanx treated with emergency silicone implant arthroplasty combined with bone grafting.
