Available online 31 July 2015 PRESENTATION OF CASE: We report a case of occult fracture of the femoral neck due to extensive ONFH in a 60-year-old man. No abnormal findings suggestive of ONFH were identified on radiographs, and Keywords: the fracture occurred spontaneously without any trauma or unusual increase in activity. The patient’s Occult fracture medical history, age, and good bone quality suggested ONFH as a possible underlying cause. Contrast- Femoral neck enhanced magnetic resonance imaging was useful in determining whether the fracture was caused by Osteonecrosis of the femoral head ONFH or was instead a simple insufficiency fracture caused by steroid use. -

Treatment options include either curettage or wide en bloc resection which causes functional disability in the hand and wrist and should be reserved only for recurrence. We present a case of recurrent trapezoid osteoblastoma previously treated with curet- tage of the trapezoid bone and a case of primary triquetral osteoblastoma.

Occult Fractures of the Proximal Femur
Deleanu et al. World Journal of Emergency Surgery (2015) 10:55 DOI 10.1186/s13017-015-0049-y WORLD JOURNAL OF EMERGENCY SURGERY RESEARCH ARTICLE Open Access Occult fractures of the proximal femur: imaging diagnosis and management of 82 cases in a regional trauma center Bogdan Deleanu1,2, Radu Prejbeanu1,2, Eleftherios Tsiridis6, Dinu Vermesan1,2, Dan Crisan1* , Horia Haragus1, Vlad Predescu4,5 and Florin Birsasteanu2,3 Abstract Background: Occult hip fractures are often difficult to identify in busy trauma units. We aimed to present our institutions experience in the diagnosis and treatment of occult fractures around the hip and to help define a clinical and radiological management algorithm. Method: We conducted a seven-year retrospective hospital medical record analysis. The electronic database was searched for ICD-10 CM codes S72.0 and S72.1 used for proximal femoral fractures upon patient discharge. We identified 34 (4.83 %) femoral neck fractures and 48 (4.42 %) trochanteric fractures labeled as occult. Results: The majority of the cases were diagnosed by primary MRI scan (57.4 %) and 12 were diagnosed by emergency CT scan (14.6 %). For the remaining cases the final diagnosis was confirmed by 72 h CT scan in 9 patients (representing 39 % of the false negative cases) or by MRI in the rest of 14 patients. MRI was best at detecting incomplete pertrochanteric fracture patterns (13.45 % of total) and incomplete fractures of the greater trochanter (3.65 % of total) respectively. It also detected the majority of Garden I femoral neck fractures (20.7 % of total). CT scanning accurately detected 100 % of Garden 2 fractures (2.44 %) and 25 % (3.65 %) of the complete pertrochanteric fractures (false negative 25 %). -

The Structure and Movement of Clarinet Playing D.M.A
The Structure and Movement of Clarinet Playing D.M.A. DOCUMENT Presented in Partial Fulfilment of the Requirements for the Degree Doctor of Musical Arts in the Graduate School of The Ohio State University By Sheri Lynn Rolf, M.D. Graduate Program in Music The Ohio State University 2018 D.M.A. Document Committee: Dr. Caroline A. Hartig, Chair Dr. David Hedgecoth Professor Katherine Borst Jones Dr. Scott McCoy Copyrighted by Sheri Lynn Rolf, M.D. 2018 Abstract The clarinet is a complex instrument that blends wood, metal, and air to create some of the world’s most beautiful sounds. Its most intricate component, however, is the human who is playing it. While the clarinet has 24 tone holes and 17 or 18 keys, the human body has 205 bones, around 700 muscles, and nearly 45 miles of nerves. A seemingly endless number of exercises and etudes are available to improve technique, but almost no one comments on how to best use the body in order to utilize these studies to maximum effect while preventing injury. The purpose of this study is to elucidate the interactions of the clarinet with the body of the person playing it. Emphasis will be placed upon the musculoskeletal system, recognizing that playing the clarinet is an activity that ultimately involves the entire body. Aspects of the skeletal system as they relate to playing the clarinet will be described, beginning with the axial skeleton. The extremities and their musculoskeletal relationships to the clarinet will then be discussed. The muscles responsible for the fine coordinated movements required for successful performance on the clarinet will be described. -

Travan1 1Department of Experimental and Clinical Medicine, Section of Anatomy, University of Udine, Italy 2Department of Medical, Surgical and Health Sciences, University of Trieste, Italy 3Department of History and Preservation of the Cultural Heritage, University of Udine, Italy 4Department of Diagnostic Imaging, University Hospital of Udine, Italy [Received: 22 July 2016; Accepted: 2 September 2016] Background: Carpal synostoses are congenital defects characterised by com- plete or incomplete coalition of two or more carpal bones. Although most of these defects are discovered only incidentally, sometimes they become clinically manifest. Among the different types of carpal coalition, the synostosis between capitate and trapezoid bones is quite rare, with only sparse data available in the literature. The aim of this report was to describe a case of capitate-trapezoid synostosis (CTS) observed in an ancient human skeleton, as well as to scrutinise the pertinent literature in order to assess for the characteristics of this type of defect, including its potential relevance to clinical practice. Materials and methods: We studied the skeletal remains of an Early Bronze Age male warrior affected by incomplete CTS. Macroscopic and radiological examina- tion of the defect was carried out. We also performed a comprehensive PubMed search in the Medline and other specialty literature databases to retrieve and analyse data relevant to the subject under consideration. -
