Chang-Yeon Kim, Mark Gentry, Debra Sala, Alice Chu
Traditional operative management of unstable, pediatric both-bone forearm fractures is fixation of both ulna and radius. Literature suggests single-bone fixation with intramedullary nailing obtains good results and is less technically demanding and invasive. This systematic review evaluates the efficacy of single-bone intramedullary nailing of pediatric both-bone forearm fractures. Medline and Embase were searched for English-language primary studies published in peer-reviewed journals. Two independent investigators extracted data...

BACKGROUND: Critical-sized bone defects are a significant challenge with limited effective reconstructive options. The Masquelet Technique (MT) offers a solution to help restore form and function. Although this technique has produced promising results; a clear mechanism has not been determined. Theories include that the induced membrane has osteogenic potential or the membrane acts as a physical barrier to prevent fibrous tissue ingrowth. We hypothesize the induced membrane acts primarily as a physical barrier and that a synthetic non-biological membrane will allow a comparable amount of bone volume in the defect site...

There is inevitable need for data regarding anthropometric measurements of each community's population. These anthropometric data have various applications, including health assessment, industrial designing, plastic & orthopedic surgery, nutritional studies, anatomical studies and forensic medicine investigations. Anthropometric parameters vary from race to race throughout the world, hence providing an anthropometric profile model of residents of different geographic regions seems to be necessary. To our knowledge, there is no report of bone parameters of the Iranian population...

BACKGROUND AND AIMS: Inhaled corticosteroids (ICSs) are crucial anti-inflammatory medications for chronic airway diseases. Studies investigating the relationship between ICSs and fractures in Asian populations are scant. We investigated whether ICSs increased the risk of low-energy fractures in patients with chronic airway diseases. METHODS: We used the Longitudinal Health Insurance Database to select patients aged 20 years and older with chronic airway diseases (asthma and COPD) between 2000 and 2011 as the base cohort...

Monteggia fractures are rare traumatic injuries in cats and dogs. Ulna repair is mostly achieved by plates. Stable radial head fixation however is challenging. Temporary position screws have to be removed due to rotation forces in the elbow joint causing screw loosening. We present a novel and simple method using a sling technique, which holds the radial head in its physiological position and allows normal elbow movement.

The question of how tetrapod limbs evolved from fins is one of the great puzzles of evolutionary biology. While palaeontologists, developmental biologists, and geneticists have made great strides in explaining the origin and early evolution of limb skeletal structures, that of the muscles remains largely unknown. The main reason is the lack of consensus about appendicular muscle homology between the closest living relatives of early tetrapods: lobe-finned fish and crown tetrapods. In the light of a recent study of these homologies, we re-examined osteological correlates of muscle attachment in the pectoral girdle, humerus, radius, and ulna of early tetrapods and their close relatives...

M Julieta Perez, Ruben M Barquez, M Monica Diaz
Here, a detailed description of the forelimbs and hindlimbs of all living species of the genus Tympanoctomys are presented. These rodents, highly adapted to desert environments, are semi-fossorial with capacity to move on the surface as well as to build burrows. The shape, structure, and size of the limbs are described. Contrary to what was expected for scratch digging semi-fossorial species, Tympanoctomys have slender humerus, radius and ulna; with narrow epicondyles of the humerus and short olecranon of the ulna with poorly developed processes...

INTRODUCTION: Diaphyseal fractures of the forearm comprise 6%-10% of all fractures in children. The treatment depends on the age and type of displacement, and conservative and surgical management with fixation of intramedullary nails, among other techniques, is valid. The aim is to show the radiological and functional outcomes, and complications of intramedullary fixation with Kirschner nails in children. MATERIALS AND METHODS: A retrospective descriptive case series of patients treated with intramedullary fixation of forearm fractures...

REVIEW
Michael Wigton, Megan Friend, Zhongyu Li
Radioulnar synostosis can cause substantial loss of function, and surgical treatment can be challenging. Recurrence of the contracture related to scar or reformation of the synostosis is problematic. Several techniques have been described for prevention of recurrence. We present a technique utilizing a free wrap around adipofascial graft for interposition and circumferential coverage of the ulna after resection of the heterotopic bone. We believe this technique has the advantages of technical simplicity, secure interposition, and reliable outcomes...

INTRODUCTION: A cortical lined impaction on the radiodorsal side of the ulnar head may be at the origin of a "second ulnar groove" (SUG). The goal of this article is to illustrate this MRI sign, prompting for further investigation of the distal radioulnar joint (DRUJ). Hence associated soft tissue pathology may be detected, which may lead to instability. MATERIAL AND METHODS: Following an anterior luxation of the ulna at the DRUJ a second cortical lined groove in a previously normal distal ulna was discovered...

Distal radius fracture (DRF) is a common injury. Treatment options have evolved and now several can be used to address even the most complex fracture patterns. Complex fractures of the distal radius and ulna can be challenging, and specific goals must be kept in mind to achieve definitive anatomical and functional restoration. This article summarizes the concepts, principles, and surgical options regarding complex DRF reconstruction.

REVIEW
M Hackl, L P Müller, T Leschinger, K Wegmann
Total elbow arthroplasty is currently most commonly carried out due to acute trauma or post-traumatic conditions. Bone defects are often present and must be considered in the (pre-)operative workup. The use of semi-constrained prostheses with a systematic cementing technique through a triceps-on approach leads to satisfying clinical results, however, the outcome is worse when compared with rheumatic patients.Primary total elbow arthroplasty for complex distal humerus fractures in the elderly patient or secondary implantation following failed conservative treatment or osteosynthesis represent possible indications for (post‑)traumatic joint replacement...

REVIEW

Management of pediatric spinal deformities requires an accurate prediction of growth spurts to allow for timely initiation of treatment and prevention of curve progression. Determining remaining growth potential is also important for avoiding prolonged unnecessary treatment, e.g. bracing for patients nearing skeletal maturity. Many clinical and radiological growth parameters have been developed to aid clinicians in growth prediction. Of these, several commonly used measures such as height and arm span growth trends, timing of menarche, and the Risser sign are mostly retrospective and lack strong predictive utility...

Caspases have functions particularly in apoptosis and inflammation. Increasing evidence indicates novel roles of these proteases in cell differentiation, including those involved in osteogenesis. This investigation provides a complex screening of osteogenic markers affected by pan caspase inhibition in micromass cultures derived from mouse forelimbs. PCR Array analysis showed significant alterations in expression of 49 osteogenic genes after 7 days of inhibition. The largest change was a decrease in CD36 expression, which was confirmed at organ level by caspase inhibition in cultured mouse ulnae followed by CD36 immunohistochemical analysis...

BACKGROUND: The Tanner-Whitehouse radius-ulna-short bone protocol (TW2 RUS) for the assessment of skeletal age (SA) is widely used to estimate the biological (skeletal) maturity status of children and adolescents. The scale for converting TW RUS ratings to an SA has been revised (TW3 RUS) and has implications for studies of youth athletes in age-group sports. OBJECTIVES: The aim of this study was to compare TW2 and TW3 RUS SAs in an international sample of male youth soccer players and to compare distributions of players by maturity status defined by each SA protocol...

In this report, two tennis players with symptoms of ulnar impaction syndrome are reviewed. Both players have neutral ulnar variance. These cases represent dynamic ulnar impaction syndrome, when the impact between ulna and carpus occurs during conditions of pronated grip. The literature and the treatment of these two cases are discussed.
