INTRODUCTION: Fractures of the radial head and neck are the most common fractures of the elbow, and account for approximately one-third of all elbow fractures. Depending on the fracture type the treatment is either conservative or surgical. There is no absolute consensus regarding optimal treatment for different fracture types. The aim of this protocol is to present the method that will be used to collect, describe and analyse the current evidence regarding the treatment of Mason II-III radial head and neck fractures...

BACKGROUND: According to currently available data, the clinical short-term results of the MoPyC radial head prosthesis (Bioprofile, Tornier, Montbonnot-Saint-Martin, France) seem favorable. However, we have encountered several implant-specific complications in recent years. Hence, this case series reports rare complications after radial head arthroplasty with the MoPyC prosthesis to make surgeons aware of their existence and to provide information about the underlying cause and possible salvage strategies...

Reconstruction of a midfacial defect can represent a difficult challenge for the plastic surgeon. Although many midfacial deformities have traumatic or congenital origins, the vast majority of head and neck defects occur after resection of malignant head and neck neoplasms. Autogenous reconstruction is now routinely performed for larger, complex defects resulting from surgical resection or trauma. In this study, the authors present 27 patients with midfacial defects reconstructed with free flaps. Twenty-two of the defects were created by surgical ablation of cancer (maxillectomy) and the others were traumatic...

Perineural invasion (PNI) is found in approximately 40% of head and neck squamous cell carcinomas (HNSCC). Despite multimodal treatment with surgery, radiation, and chemotherapy, locoregional recurrences and distant metastases occur at higher rates, and overall survival is decreased by 40% compared to HNSCC without PNI. In vitro studies of the pathways involved in HNSCC PNI have historically been challenging given the lack of a consistent, reproducible assay. Described here is the adaptation of the dorsal root ganglion (DRG) assay for the examination of PNI in HNSCC...

Snapping elbow is a rare condition, which has various possible causes such as impinged plica, annular ligament, or other extra-articular causes. We report a case of 15-year-old boy who had had snapping elbow and sudden-onset flexion contracture of the elbow. Simple radiographs showed bilateral anterior dislocation of hypoplastic radial heads. Magnetic resonance images with the elbow extended as much as possible showed that the annular ligament hemmed the dislocated radial neck. By surgical incision of the annular ligament which checkreined the radial neck, the patients could regain full extension of the elbow...

: Pediatric radial neck fractures are uncommon. Severely displaced and angulated fractures usually require treatment. Our goals for treatment are to avoid incision, reduce the fracture adequately with no reduction loss, and achieve good postoperative function. We aimed to observe the clinical outcomes of closed reduction with the percutaneous leverage technique and internal fixation with Kirschner-wires (K-wires) to treat angulated radial neck fractures in children.From January 2011 to April 2013, we treated 16 cases of angulated radial neck fracture in 12 boys and 4 girls...

BACKGROUND: A principal reason for flap compromise in oral and maxillofacial head and neck surgery, and failure of a free flap transfer, is thrombosis of a drainage vein such as the internal jugular vein. This study characterized flap compromise caused by internal jugular vein thrombosis after a free flap transfer, and its management. PATIENTS AND METHODS: A retrospective clinical study was conducted of 306 consecutive microvascular free flaps performed for 305 patients with head and neck cancer from March 2003 to March 2013 at the Department of Oral and Maxillofacial Surgery at Beijing Stomatological Hospital, Capital Medical University...

: Fractures of the radial head and radial neck correspond to 1.7-5.4% of all fractures and approximately 30% may present associated injuries. In the literature, there are few reports of radial head fracture with posterior interosseous nerve injury. This study aimed to report a case of radial head fracture associated with posterior interosseous nerve injury. CASE REPORT: A male patient, aged 42 years, sought medical care after falling from a skateboard. The patient related pain and limitation of movement in the right elbow and difficulty to extend the fingers of the right hand...

To develop a novel method to monitor external anatomical changes in head and neck cancer patients in order to triage possible adaptive radiotherapy needs METHODS: The presented approach aims to provide information on internal anatomical changes based on variations observed in external anatomy. Setup Cone Beam Computed Tomography (CBCT) images are processed to produce an accurate external contour of the patient's skin. After registering the CBCTs to the reference planning CT, the external contours from each CBCT are transferred to the initial- first week - CBCT...

Unruptured vertebral arteries dissecting aneurysms have a benign clinical course. The most common symptoms compromise headache, neck pain, dizziness and vomiting. The optimal endovascular treatment option remains controversial. Reconstructive techniques have many advantages over deconstructive ones since the advent of flow diverters such as the Pipeline embolization device (PED). Here, we present a case successfully treated with a PED through a combination of the radial access and advancement of the Marksman catheter into the contralateral vertebral artery due to the special angio-architecture of the patient...

BACKGROUND: Flow diverter (FD) malapposition is associated with stroke-related complications. We document the use of self-expanding nitinol stents to remove/reduce the ledge of a FD deployed for aneurysm treatment. METHODS: We identified five patients who were treated with the Pipeline embolization device (PED) in conjunction with a Neuroform EZ stent for inadequate wall apposition of the ends of the FD at our institution between May 2014 and July 2015. Among other parameters, angiographic results, cone-beam computed tomography assessment of wall apposition and patient clinical outcome were evaluated...

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...
