Avoidance of Reamer Breakage During ACL Reconstruction With Flexible Reamer System
Authors’ Response: We greatly appreciate the viewpoints of Dr Jaiman concerning the timing/use of the 4.5-mm reamer when utilizing a flexible reamer for establishing a femoral tunnel. Using a flexible reamer system is very advantageous in creating a low femoral tunnel especially in the current context of concomitant anterolateral ligament (ALL) reconstruction or posterolateral corner reconstruc...
متن کاملAnterior Cruciate Ligament Reconstruction Using a Flexible Reamer System
Anatomic reconstruction of the anterior cruciate ligament (ACL) has been shown to improve stability of the knee, particularly rotational stability, potentially leading to superior clinical outcomes and a shorter return to sport. Nonanatomic ACL reconstruction has been linked to graft failure and abnormal cartilage loading thought to contribute to progression of degenerative joint disease. Use o...
متن کاملEndobronchial pulp-canal reamer extracted with the fibreoptic bronchoscope.
A 45-year-old man had had an unproductive and persistent cough for two weeks, after aspiration of a pulpcanal reamer. A chest radiograph revealed the aspirated object lodged in the posterior basal segment of the lower left lobe (figure). Because the object was inaccessible to the rigid bronchoscope, the patient was referred to a surgeon with a view to thoractomy. He invited us to try to remove ...
متن کاملTapered, Fluted Femoral Fixation
CLINICAL/SURGICAL PEARLS: 1. Determining the highest level of supportive femoral bone is important to place the taper into this bone. An extended trochanteric osteotomy is useful for removal of the old stem and facilitates placement of a relatively straight, tapered, fluted stem down a bowed femur, thus preventing anterior perforation of the stem through the anterior cortex. The intact diaphysi...
متن کاملTapered Holey Fiber
Adiabatically tapered holey fibers are shown to be potentially useful for guided-wave spot-size and numerical aperture conversion. Conditions for adiabaticity and design guidelines are provided in terms of the effective index model. We also present finite-difference time-domain calculations of down-tapered holey fiber, showing that large spot size conversion factors are obtainable with minimal ...
