– See – Pediatric Both Bone Frx – Deforming Forces – Discussion of Blount Fractures – Implants for Fractures of the Radius and Ulna – Plating Techniques – Indications for Operative Treatment: – all displaced, unstable fractures of the radius and ulna in adults; – radial shaft fractures: all displaced fractures of the radius with … Read more
Location of Frx distal 1/3 : 75% middle 1/3 : 18% proximal 1/3: 7% Surgical Approach Proximal Radius Fx (Thompson) Distal Radius Fx (Henry) Comminution side of comminution may dictate plate placement; comminution involving more than 1/3 of circumference of shaft may necessitate bone grafting; bone grafting should be away from interosseous membrane to decrease risk for … Read more
– Discussion: – often occurs as a result of degenerative disc disease and facet deficiency; – it is often associated w/ intersegmental instability and w/ central stenosis; – more commonly involves older black females and diabetics (affects females 6 times as much as males); – involves L4-L5 … Read more
– Fractures Subtypes: – capitellar and coronal shear frx – distal humeral frx – lateral condyle frx – medial condyle frx – Muller’s Classfication: – type A: extra-articular fracture; – type B: uni-condylar fracture; – type C: bi-condylar fracture; – controversies: – total elbow replacement – Distal humeral fractures treated with noncustom total elbow … Read more
– Discussion: – anesthesia: insist on general anesthesia rather than regional anesthesia for the following reasons: – it is essential that the patient not move during delicate portions of the case; – it is often helpful to paralyze the patient during the fracture … Read more
– Technique: – it is helpful to have the patient paralyzed during the reduction (requires general anesthesia); – anatomic reduction of the condyles is performed first; – remember that the common factor in fixation failure in these fractures is comminution and/or osteoporosis; – best-fit method: … Read more
– indicated for PSVT; – if arrhythmias are not due to reentry involving the AV node or sinus node (eg, atrial flutter, atrial fibrillation, atrial or ventricular tachycardias), adenosine will not terminate the arrhythmia but may produce transient AV or ventriculoatrial block that may clarify dx; – Dose: – half-life of adenosine is less than … Read more
