BACKGROUND: Phalangeal microgeodic disease is a rare and benign self-limited condition involving the phalanges, often in the setting of cold exposure, with characteristic MR imaging abnormalities. Radiographic case descriptions are predominantly from Asia and Europe, with only seven cases using MR to characterize phalangeal microgeodic disease. OBJECTIVE: In this study we describe the MR imaging appearance of unusual and striking phalangeal signal abnormality compatible with phalangeal microgeodic disease at our institution in North America...

We describe a rare and sporadic condition, characterized by swan neck deformity in hands, hip osteoarthritis in adulthood and malformations of the middle phalanges with an angel shape. The patient is a 4 year old boy who suffered hand trauma and on x-ray examination he was diagnosed with angel-shaped phalango-epiphyseal dysplasia. Based on this diagnosis, his mother, who suffered from constant pain in her hips and lower limbs, was diagnosed with this syndrome as well.

The ostrich is a highly cursorial bipedal land animal with a permanently elevated metatarsophalangeal joint supported by only two toes. Although locomotor kinematics in walking and running ostriches have been examined, these studies have been largely limited to above the metatarsophalangeal joint. In this study, kinematic data of all major toe joints were collected from gaits with double support (slow walking) to running during stance period in a semi-natural setup with two selected cooperative ostriches. Statistical analyses were conducted to investigate the effect of locomotor gait on toe joint kinematics...

AIM: The effect of a supernumerary X chromosome on bones has not been reported and this study evaluated bone mineral status and metabolism in non-mosaic triple X syndrome. METHODS: This cross-sectional study comprised 19 girls, with a median age of 10.9 years, with nonmosaic triple X syndrome and a control group matched for age and body size. We studied ionised and total calcium, phosphate, parathyroid hormone (PTH), 25-hydroxyvitamin D (25(OH)D), 1,25-dihydroxyvitamin D, osteocalcin, bone alkaline phosphatase levels and urinary deoxypyridinoline concentrations...

An intrinsic timing mechanism specifies the positional values of the zeugopod (i.e. radius/ulna) and then autopod (i.e. wrist/digits) segments during limb development. Here we have addressed if this timing mechanism ensures that patterning events occur only once by grafting GFP-expressing autopod progenitor cells to the earlier host signaling environment of zeugopod progenitor cells. We show that early and late autopod progenitors fated for the wrist and phalanges, respectively, both contribute to the entire host autopod indicating that the autopod positional value is irreversibly determined as revealed by Hoxa13 expression...

Age estimation of living individuals aged less than 13, 18 or 21 years, which are some relevant legal ages in most European countries, is currently problematic in the forensic context. Thus, numerous methods are available for legal authorities, although their efficiency can be discussed. For those reasons, we aimed to propose a new method, based on the biometric analysis of hand bones. 451 hand radiographs of French individuals under the age of 21 were retrospectively analyzed. This total sample was divided into three subgroups bounded by the relevant legal ages previously mentioned: 0-13, 13-18 and 18-21 years...

Degenerative and traumatic ligament lesions of the carpometacarpal joints frequently occur at the thumb ray, whereas the carpometacarpal amphiarthrosis of other finger rays are rarely affected. The metacarpophalangeal and interphalangeal joints of the thumb and fingers are stabilized by bilaterally running collateral ligaments and palmar plates. At the base of the metacarpophalangeal joints, several ligaments of the extensor hoods guide the extensor tendons and coordinate the fine motoric skills of phalangeal flexing and extending...

Large body size of ectothermic species can be correlated with high life expectancy. We assessed the longevity of the world's largest chameleon, the Parson's chameleon Calumma parsonii from Madagascar by using skeletochronology of phalanges taken from preserved specimens held in European natural history museums. Due to the high bone resorption we can provide only the minimum age of each specimen. The highest minimum age detected was nine years for a male and eight years for a female, confirming that this species is exceptionally long living among chameleons...

A seven-month old female presented with left tibial hemimelia (or congenital tibial aplasia; Weber type VIIb, Jones et al type 1a), seven-toed preaxial polydactyly, and severe club foot (congenital talipes equinovarus). Definitive amputation surgery disarticulated the lower limb at the knee. This case report describes the anatomical findings of a systematic post-amputation examination of the lower limb's superficial dissection, X-rays, and computed tomography (CT) scans. From the X-rays and CT scans, we found curved and overlapping preaxial supernumerary toes, hypoplastic first metatarsal, lack of middle and distal phalanges in one supernumerary toe, three tarsal bones, hypoplastic middle phalanx and no distal phalanx for fourth toe, and no middle or distal phalanges for fifth toe...

Background: The success of tissue transplantation and long-term tissue stability after wound healing depends on sufficient tissue perfusion. Laser Doppler-supported procedures allow for an objective measurement of relative tissue perfusion. The development of Speckle-based Laser Doppler imaging now enables a real-time representation of tissue perfusion. The perfusion of tissues relevant in plastic surgery such as scars, phalangeal replantations and burn wounds were systematically analysed by Laser Speckle Contrast Analysis (LASCA) imaging...

This case presents surgical treatment of a unique form of syndactyly: an isolated fenestrated, complex, crisscross syndactyly of the right middle and ring fingers. A 2-year-old boy presented with the ring finger lying dorsal and the middle finger lying volar, with the middle phalanges syndactylized. A surgical release was performed with a subsequent z-plasty, 2 years later, for scar elongation. At the age of 4, he has essentially full function of his hand with minimal limitations. This case demonstrates that 2 digits that were syndactylized in a coronal plane (ring finger dorsal and middle finger volar) can be successfully surgically separated...

Acro-osteolysis is a rare disease characterized by bone resorption involving the distal phalanges of the hand. We present a unique case of progressive acro-osteolysis of the distal phalanges and articular calcifications in a patient with scleroderma. The calcified deposit in a proximal interphalangeal joint was excised under local anesthesia. The medical treatment was arranged under the supervision of a rheumatologist.

RATIONALE: Florid reactive periostitis is a rare, benign bone and chondrogenic lesion that develops most frequently in the phalanges of the hands. Although the definitive cause of florid reactive periostitis is unknown, the major inciting factor is generally considered to be trauma, including repetitive minor trauma. PATIENT CONCERNS: We present a case of florid reactive periostitis affecting two contiguous phalangeal bones of the left fifth phalange of a 23-year-old male professional boxer...

INTRODUCTION: High energy injuries to the midfoot and forefoot are highly morbid injury groups that are relatively unstudied in the literature. Patients sustaining injuries of this region are challenging to counsel at the time of injury because so little is known about the short and long term results of these injuries. The purpose of this study was to investigate injury specific factors that were predictive of amputation in patients sustaining high energy midfoot and forefoot injuries...

Hand fractures are one of the most common causes for presenting to the emergency room. Metacarpal fractures count about 18 to 44% of all hand fractures, and are most often standalone closed injuries, without misplacement, not needing operative treatment. We present a case in which osteosynthesis with plates and screws was used to reduce two metacarpal fractures in order to allow an early motion recovery, despite the fact that a small portion of the periosteum needed to be removed. The type of fractures were misclassified according to the radiological findings, therefore the correct diagnosis was established during surgery...

In this paper we report the discovery of non-plumage soft tissues in Confuciusornis, a basal beaked bird from the Early Cretaceous Jehol Biota in northeastern China. Various soft tissues are visualized and interpreted through the use of laser-stimulated fluorescence, providing much novel anatomical information about this early bird, specifically reticulate scales covering the feet, and the well-developed and robust pro- and postpatagium. We also include a direct comparison between the forelimb soft tissues of Confuciusornis and modern avian patagia...

BACKGROUND: At present, most bone fixation devices are made of metal, and are applied to prevent the postoperative dislocation of bone fragments. The major issues with such metal bone fixation devices are the necessity for secondary surgery to remove the devices, stress shielding of bone, stimulation and erosion of bone and soft tissue, and limited biocompatibility. To mitigate these problems, we aimed to assess use of a flexible absorbable polymer bone fixation devices. These devices were certified for use in China in September, 2015...
