INTRODUCTION: The debate regarding the description on classification and nomenclature of the injury which includes olecranon fracture associated with radial neck fractures in children is ongoing. We report two pediatric cases that could not be classified in a Monteggia-equivalents system and were treated with open reduction and k-wire fixation. The aim of this study was to perform a systematic review regarding pediatric radial neck fractures associated with olecranon fractures and presentation of two pediatric cases of olecranon fractures associated with radial neck fractures with radiocapitellar dislocation...

Controversy exists regarding the use of Duplex Ultrasound (DUS) in addition to the Modified Allen's Test (MAT) for the assessment of collateral circulation prior to elevation of the Radial Forearm Free Flap (RFFF). A survey amongst members of BAOMS Head & Neck Oncology Subspecialty Interest Group and a completed local audit was undertaken to assess the need for DUS. Data for the initial audit was collected retrospectively between 2010 and 2013. Both MAT and DUS was performed routinely during this period. The results of the survey and initial audit led to a change in practice and DUS was no longer requested...

Monteggia fractures comprise a small subset of fractures in the pediatric population that are normally reduced nonoperatively. Complex Monteggia fractures can be more difficult to identify and require operative intervention. We describe a case of a Bado type I Monteggia fracture with a posteriorly dislocated radial head and neck fracture that has not been described before in the literature. The patient required advanced imaging because of ossification delays and led to an operative intervention to reduce the radial head and neck...

A model based on a specific phantom, called QuAArC, has been designed for the evaluation of planning and verification systems of complex radiotherapy treatments, such as volumetric modulated arc therapy (VMAT). This model uses the high accuracy provided by the Monte Carlo (MC) simulation of log files and allows the experimental feedback from the high spatial resolution of films hosted in QuAArC. This cylindrical phantom was specifically designed to host films rolled at different radial distances able to take into account the entrance fluence and the 3D dose distribution...

Romosozumab (Romo), a humanized sclerostin antibody, is a bone-forming agent under development for treatment of osteoporosis. To examine the effects of Romo on bone quality, mature cynomolgus monkeys (cynos) were treated 4 months post-ovariectomy (OVX) with vehicle, 3, or 30 mg/kg Romo for 12 months, or with 30 mg/kg Romo for 6 months followed by vehicle for 6 months (30/0). Serum bone formation markers were increased by Romo during the first 6 months, corresponding to increased cancellous, endocortical, and periosteal bone formation in rib and iliac biopsies at months 3 and 6...

PURPOSE: To suggest a definition of dose deposition anisotropy for the purpose of ad hoc adaptation of intensity modulated arc therapy (IMRT) and volumetric arc therapy (VMAT), particularly in the vicinity of important organs at risk (OAR), also for large deformations. METHODS: Beam's-eye-view (BEV) based fluence warping is a standard adaptation method with disadvantages for strongly varying OAR shapes. 2-Step-adaptation overcomes these difficulties by a deeper analysis of the 3D properties of adaptation processes, but requires separate arcs for every OAR to spare, which makes it impractical for cases with multiple OARs...

Radial artery is an important consistent vessel of the upper limb. It is a useful vascular access site for coronary procedures and its reliable anatomy has resulted in an elevation of radial forearm flaps for reconstructive surgeries of head and neck. Technical failures, in both the procedures, are mainly due to anatomical variations, such as radial loops, ectopic radial arteries or tortuosity in the vessel. We present a rare and a unique anomalous medial branch of the radial artery spiraling around the flexor carpi radialis muscle in the forearm with a high rising superficial palmar branch of radial artery...

BACKGROUND: The role of elbow contracture release in the very young is unclear, with existing studies reporting conflicting results. This study evaluated the long-term results after open elbow contracture release in patients aged younger than 18 years. METHODS: Between 1994 and 2012, 32 patients underwent open elbow contracture release at a mean age of 13.8 years (range, 5-18 years), and their outcomes were reviewed. The primary cause was traumatic in 30 patients (4 radial head/neck fractures, 5 intra-articular distal humeral fractures, 11 extra-articular distal humeral fractures, 10 complex fracture-dislocations), and the mean time from the index injury to contracture release was 16...

BACKGROUND: Double-strand lateral ulnar collateral ligament (LUCL) reconstruction is an effective treatment for posterolateral rotatory instability (PLRI) of the elbow, but anatomic landmarks for ulnar tunnel placement are often difficult to identify intraoperatively, which potentially can result in a nonanatomic LUCL reconstruction. This study investigated the effect of ulnar tunnel location on joint stability in double-strand LUCL reconstruction. METHODS: PLRI was artificially created in 7 cadaveric elbows, and double-strand LUCL reconstruction was performed...

A simple chemical bath deposition is used to coat a complex porous ceramic scaffold with a conformal Ni layer. The resulting composite is used as a solid oxide fuel cell electrode, and its electrochemical response is measured in humidified hydrogen. X-ray tomography is used to determine the microstructural characteristics of the uncoated and Ni-coated porous structure, which include the surface area to total volume, the radial pore size, and the size of the necks between the pores.

A low origin of the radial artery is a rare anatomical variation, with the incidence estimated at 0.2 %. This report presents a previously unrecorded case of an unusual distal origin of the radial artery, co-occurring with a double recurrent radial artery. The radial artery arose under the pronator teres muscle, 76 mm below the intercondylar line of the humerus. After emerging from under the tendon of the pronator teres muscle, the radial artery took a typical course and terminated in the deep palmar arch...

Salvatore Bisicchia, Cosimo Tudisco
Fracture-dislocations of the elbow can be difficult to treat, with unsatisfactory results in some cases. In general, it is preferable to preserve the fractured radial head when possible, but some patients present a unique treatment challenge because of extremely comminuted fractures and bone loss. In these cases, the only options available are radial head prosthesis or allograft. The authors present a case of a 45-year-old man with a fracture-dislocation of the left elbow that was treated with an allograft of the radial head and neck because of extreme comminution of the fracture...

BACKGROUND: The radiocapitellar line (RCL) was originally described for evaluation of the alignment of the RC joint on lateral images of the elbow. Although, many authors have translated the utilization of RCL into coronal imaging, previous studies have not been performed to confirm validity. The purpose of this paper was to identify an accurate way of evaluating pediatric RC alignment in the coronal plane. METHODS: Thirty-seven anteroposterior (AP) radiographs of 37 children were evaluated to determine the position of the RC joint in the coronal plane...

BACKGROUND: Although the etiology of primary femoroacetabular impingement (FAI) is considered developmental, the underlying pathogenic mechanisms remain poorly understood. In particular, research identifying etiologic factors associated with pincer FAI is limited. Knowledge of the physiologic growth patterns of the acetabulum during skeletal maturation might allow conclusions on deviations from normal development that could contribute to pincer-related pathomorphologies. QUESTIONS/PURPOSES: In a population of healthy children, we asked if there were any differences related to skeletal maturation with regard to (1) acetabular version; (2) acetabular depth/width ratio; and (3) femoral head coverage in the same children as assessed by MRIs obtained 1 year apart...
