Kristopher B McCall, David Y Chong
A pediatric patient presenting with an open forearm fracture with segmental defect is rare, and the pediatric orthopedic literature to guide treatment is sparse. There are several described methods to treat the defect, including bone grafting and bone transport techniques. In addition, there are reports of fibular regeneration after resection if the periosteum is left intact. We present a case report of complete regeneration of over half of a pediatric radial shaft with an intact periosteum, after traumatic extrusion from an open fracture...

South Africa has had an increase in rates of crime, interpersonal violence and homicide since the introduction of democracy in 1994. Forensic osteological standards was lacking for South Africans of different population groups necessitating the generation of new standards for forensic identification of individuals from skeletal remains. For these reasons, there is a concerted demand for methods of identifying skeletal remains with sex being amongst the most important of the biological characteristics required...

Previous studies have investigated the relationship between ultrasound-measured muscle thickness (MT) and individual muscle cross-sectional area (CSA); however, the forearm muscle had not yet been studied. The purpose of this study was to examine the relationship between forearm MT by ultrasound and the muscle CSA of the forearm obtained by magnetic resonance imaging (MRI). Ten young and middle-aged adults had both ultrasound and MRI measurements at 30% the distance from the styloid process of the ulna to the head of the radius...

Birds change the shape and area of their wings to an exceptional degree, surpassing insects, bats and aircraft in their ability to morph their wings for a variety of tasks. This morphing is governed by a musculoskeletal system, which couples elbow and wrist motion. Since the discovery of this effect in 1839, the planar 'drawing parallels' mechanism has been used to explain the coupling. Remarkably, this mechanism has never been corroborated from quantitative motion data. Therefore, we measured how the wing skeleton of a pigeon (Columba livia) moves during morphing...

The aim of this study was to determine the factors that may predict failure of closed reduction and casting of diaphyseal forearm fractures in children. Demographic and radiographic data of children with closed reduction and casting of these fractures in the emergency department were evaluated. Of 174 patients with adequate follow-up to union, 19 (11%) required a repeat procedure. Risk factors for repeat reduction included translation of 50% or more in any plane, age more than 9 years, complete fracture of the radius, and follow-up angulation of the radius more than 15° on lateral radiographs or of the ulna more than 10° on anteroposterior radiographs...

Sigmodontinae rodents constitute the second-largest subfamily among mammals. Alongside the taxonomic diversity, they are also ecologically diverse, exhibiting a wide array of locomotion modes, with semifossorial, terrestrial, semiaquatic, scansorial, arboreal, and saltatorial forms. To understand the ecomorphologic aspects that allow these rodents to display such locomotion diversity, we analyzed 35 qualitative characters of the appendicular skeleton (humerus, ulna, radius, scapula, femur, tibia, ilium, ischium and pubis) in 795 specimens belonging to 64 species, 34 genera and 10 tribes, representing all locomotion modes assigned to this subfamily...

The purpose of this study was to determine the rate of cast-related complications when using split or intact casts. A total of 60 patients aged 3 to 13 years with closed shaft or distal third radius and ulna fractures requiring reduction were recruited for this study. Patients underwent closed reduction under sedation and were placed into a long-arm fiberglass cast with 1 of 3 modifications: no valve, univalve, or bivalve. Patients were followed to 6 weeks after reduction or surgical treatment if required. The frequency of neurovascular injury, cast saw injury, unplanned office visits, and cast modifications, the need for operative intervention, and pain levels through the follow-up period were recorded...

Forearm fractures in children complicated with non-union are uncommon. Various methods have previously been reported to manage this condition. Well documented techniques would include iliac crest grafting, cancellous insert grafting, ulnar segment grafting, cortical tibial grafting, vascularized fibular grafting and bone transport by ring fixation. The authors present a case of a child with an atrophic non-union of the ulna who was successfully treated with a cortico-cancellous tibial strut bone graft.

Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic or absent radii, and first metacarpal to hypoplastic ulna and carpal bone anomalies. Cardiac involvement ranges from asymptomatic conduction disturbances to multiple structural defects...

In this article, we present two middle-aged female patients with ulna fracture or medial meniscal tear resulting from dog-related injuries, which are not common. Both patients mentioned that pain started after their dogs pulled away their collar ropes strongly and suddenly. Both patients had postmenopausal osteoporosis and degenerative osteoarthritis. For this reason, ulna fracture and meniscus tear had developed with low-energy trauma resulting from dog-related injuries.
