Three-compartment arthrography has been advocated in the current literature for evaluation of the intrinsic ligaments of the wrist. Previous techniques for distal radioulnar joint (DRUJ) injection introduce the needle directly into the joint space. As is done in shoulder arthrography, however, the needle tip can be positioned at the distal-radial margin of… (More)
MRI allows non-invasive assessment of intervertebral disc degeneration with the added clinical benefit of using non-ionizing radiation. What has remained unclear is the relationship between assessed disc degeneration and lumbar spine kinematics. Kinematic outcomes of 54 multi-segment (L1-Sacrum) lumbar spine specimens were calculated to discover if such an… (More)
Dislocations of the knee are relatively uncommon injuries. However, the incidence of this injury appears to be increasing. Knee dislocations are most often high velocity blunt injuries, with motor vehicle accidents being a frequent etiology. Other causes include falls from height, athletic injuries, farming and industrial accidents, and even low velocity… (More)
A 35-year-old male athlete presented with acute pain plantar to the hallux metatarsophalangeal joint following jumping to catch a basketball.
Dear Colleague: Precise measurements and clear identifi cation of bony landmarks are key to successful orthopedic surgery. The use of computer-assisted navigation, especially in minimally invasive surgery, maintains clear visibility during procedures, allowing the surgeon to obtain accurate measurements necessary for positioning implants in total hip… (More)
BACKGROUND Iliosacral screw fixation has become a common method for surgical stabilization of acute disruptions of the pelvic ring. Placement of iliosacral screws into the first sacral (S1) body is the preferred method of fixation, but size limitations and sacral dysmorphism may preclude S1 fixation. In these clinical situations, fixation into the second… (More)
Patellofemoral instability is related to anatomy. Magnetic resonance imaging (MRI) provides anatomic detail, but spoiled gradient echo (SPGR) imaging during isometric quadriceps contraction provides objective functional data for diagnosing patellofemoral laxity. Knee MRI studies and medical charts of 398 patients were retrospectively reviewed. Two… (More)
