Biomechanical Evaluation of Two Methods of Humeral Shaft Fixation
This study compared the biomechanical performance of 4.5-mm limited-contact dynamic compression plates and 3.5-mm locking compression plates for the fixation of unstable humeral shaft fractures. Composite humeri were divided into two groups: 3.5mm LC and 4.5-mm LCDC plates. Osteotomy gaps of 5-mm, simulating diaphyseal comminution, were created. Stiffness tests were performed in anterior-poster...
متن کاملAnterior Shoulder Dislocation and Ipsilateral Humeral Shaft Fracture
Simultaneous dislocation of shoulder and humeral shaft fracture is a rare injury, and there is no clear protocol for its treatment. Herein we present a case of a 15-year-old boy, who suffered from a job-related accident and sustained fracture of humeral shaft associated with ipsilateral anterior shoulder dislocation and fracture of greater tuberosity 15 years ago. He received closed reduction o...
متن کاملThe Mechanical Benefit of Medial Support Screws in Locking Plating of Proximal Humerus Fractures
BACKGROUND The purpose of this study was to evaluate the biomechanical advantages of medial support screws (MSSs) in the locking proximal humeral plate for treating proximal humerus fractures. METHODS Thirty synthetic left humeri were randomly divided into 3 subgroups to establish two-part surgical neck fracture models of proximal humerus. All fractures were fixed with a locking proximal hume...

متن کاملFracture Union in Closed Interlocking Nail in Humeral Shaft Fractures
BACKGROUND Fracture shaft humerus is a major cause of morbidity in patients with upper extremity injuries. The aim of this study was to evaluate the outcome of interlocking nail in humeral shaft fractures. METHODS This study was conducted in the Department of Orthopedic Surgery in SMS and R Sharda University from January 2010 to November 2013. Seventy-eight patients were recruited from emerge...
