Norell Rosado, Elizabeth Ryzna, Emalee G Flaherty
Fractures are the second most common abusive injury occurring in young children, particularly those under 2 years of age. The humerus is often affected. To better identify factors discriminating between abusive and non-abusive humerus fractures, this retrospective study examined the characteristics and mechanisms of injuries causing humerus fractures in children less than 18 months of age. Electronic medical records were reviewed for eligible patients evaluated between September 1, 2007 and January 1, 2012 at two children's hospitals in Chicago, IL...

REVIEW
Adil Naeem, Hugo Gemal, Duncan Reed
A fracture of the mandible is a common trauma presentation amongst young males and represents one of the most frequently encountered fractured bones within the viscerocranium. Historically, assault was the dominant contributing factor but now due to the increased number of vehicles used per capita, motor vehicle accidents are the primary cause. Mandibular fractures can be classified anatomically, by dentition, by muscle group and by severity. The fracture may also be closed, open, comminuted, displaced or pathological...

We identified an unusual case of the medial epiondyle physeal fracture, which has been caused by a direct blow, accompanied with complete stripping of soft tissue. Surgery was performed for open reduction and internal fixation of the medial epicondyle and reattachment of the anterior oblique bundle of medial collateral ligament and flexor muscle origin. Six months after the surgery, strength of wrist flexion and forearm pronation, range of motion and valgus stability of the left elbow had recovered. One year after the injury, radiographs showed atrophy and sclerosis of the medial epicondylar apophysis...

Aaron Wynkoop, Osy Ndubaku, Paul M Carpentier, Jeffrey B Peck, Norman E Walter, Patrick Atkinson
BACKGROUND: The end screw in a fracture plate creates the greatest resistance to bending. For osteoporotic fractures treated with plates, there is some question as to the optimal screw insertion technique for the screw farthest from the fracture. A locked, oblique end screw was previously shown to increase resistance to periprosthetic fracture. It is unknown, however, how this end screw configuration would resist pullout when subjected to bending. METHODS: Narrow, low contact 3...

Dauwe Jan, Van der Cruyssen Fréderic, De Smet Luc
INTRODUCTION: Fractures of the sesamoid bones of the metacarpophalangeal joint (MCPJ) are a rare pathology in hand trauma. Only a few case reports and case series were found in literature. The diagnosis of an ulnar sesamoid bone fracture of the MCPJ is difficult and can pose a differential diagnostic problem with Stener lesions or ulnar collateral ligament (UCL) instability. This pathology is frequently missed with subsequent poor functional outcomes. Correct and early diagnosis is important as this will allow for correct treatment with full recovery of function without sequelae...

BACKGROUND: We present a classification system that progresses in severity, indicates the pathomechanics that cause the fracture and therefore guides the surgeon to what fixation will be necessary by which approach. METHODS: The primary posterior malleolar fracture fragments were characterized into 3 groups. A type 1 fracture was described as a small extra-articular posterior malleolar primary fragment. Type 2 fractures consisted of a primary fragment of the posterolateral triangle of the tibia (Volkmann area)...

PURPOSE: Rib fractures are the most common skeletal thoracic injuries resulting from blunt chest trauma. Half of the rib fractures are not detected upon a precise physical evaluation and radiographs. Recently ultrasonography (USG) has been investigated to detect rib fractures. But based on literature the usefulness of USG varies widely. This study was conducted to investigate the role of USG in the detection of possible rib fractures in comparison with radiography. METHODS: In this cross-sectional study, consecutive patients with minor blunt chest trauma and suspected rib fractures presenting in Imam Reza Hospital located in Mashhad-Iran, between April 2013 and October 2013 were assessed by USG and radiography...

The technique for application of implants at the sciatic buttress has been well described in the pelvic and acetabular fracture reconstruction literature. We described a new use of the inlet-obturator oblique view for the identification of the anterior inferior iliac spine, which is the entry point of implants, and we provide a detailed fluoroscopic and radiographic description of this view. A small series of 15 patients who underwent an application of an anterior inferior pelvic external (supra-acetabular) fixator via this technique is presented...

BACKGROUND: It is possible that some hamate hook fractures are not diagnosed or treated, thereby affecting the study of their natural history. Study of the prevalence of incidental hamate hook fractures, nonunions, and other abnormalities on computed tomography (CT) ordered for another reason could document a subset of undiagnosed and untreated hamate hook fractures which might change our understanding about the natural history. METHODS: Reports of 2489 hand, wrist, and forearm CT scans for hamate hook abnormalities were searched...
