ABSTRACT
In a patient with a distal common bile duct stone, a fracture of the traction wire of the basket occurring during the performance of mechanical lithotripsy resulted in the impaction of the lithotripter basket with a stone. The impacted lithotripter basket combined with a fracture of the traction wire is a rare complication of endoscopic stone removal. We were able to pull the impacted basket using an Amplatz goose-neck snare inserted via the percutaneous transhepatic route, which resulted in the freeing of the entrapped stone into the dilated supra-ampullary bile duct. The fractured traction wire and basket could be safely removed by pulling the traction wire from the mouth. The present report is the first to describe the safe and effective use of an Amplatz goose-neck snare for the management of a lithotripter basket impacted with a stone and a fractured traction wire.

OBJECTIVE: To identify the usefulness of using a locally built Khon Kaen Mobile Traction Unit (KK-MTU) to assist clarification of anatomy of the spines, decompression of cauda equina and spinal nerve roots, posterior relocation of the diseased spines, application of pedicular screws and fixation of the spines in anterior spondylolisthesis surgery. MATERIAL AND METHOD: Fifty patients with spondylolisthesis had surgery from orthopedic surgeons that used the KK-MTU in a clinical trials phase to assist the operation at the Department of Orthopedics Surgery, Khon Kaen Hospital, between January 6, 2006 and February 11, 2008. RESULTS: Outcomes of spondylolisthesis surgery in 50 patients with the application of this equipment suggests that the operation time and blood loss can be reduced because of the reduction of abdominal pressure. The surgeons also stated that the unit helped to clarify the anatomy of the spines. Moreover, it can ease complications that might arise during the operation due to its facilitated decompression, fixation, and application of other instruments during the surgeries. CONCLUSION: Newly locally built KK-MTU could facilitate orthopedic surgeries by clarifying the anatomy, reducing, decompressing, and having tools fixed for spondylolisthesis surgery.

La corrección quirúrgica de la escoliosis idiopática es tema de controversia, en cuanto a su efectividad en el plano transverso. La deformidad no ocurre por rotación sino por desplazamiento ventrolateral de la columna. Pensamos que con un nuevo instrumento, siguiendo la técnica de Cotrel-Dubousset y con la experiencia del Dr. Luque, en México, se logrará la corrección en todos los planos. Los pacientes tratados tenían una escoliosis idiopática operaron 8, aquí mostramos la evaluación postoperatoria de 2, siete meses después de la cirugía, donde se logró la disminución de la escoliosis costal y la medialización de las vértebras en los planos sagital, coronal y transverso, se espera que la modificación será mayor además de la ausencia de complicaciones postquirúrgicas

A dental appliances tensile dynamometer was developed remove direct bonded orthodontic brackets from the tooth, without necessity of extracting this late; this means that the essay is realized with the dental organ resting in its alveolus of a living patient. The apparatus basically consists of a metalic tube, containing a fixed blade (or a S-like structure) tied to a metalic wire. When the wire is conected to the bracket, the dynamometer is pulled, the blade is submitted to a tensile effort which is dected by two extensometers that send electric pulses to a plotter or to a micro-computer, already calibrated to quantify the traction force value necessary to remove the bracket. It is possible to use this dynamometer in many other situations, as to verify the bond strength of dental adhesives to the various dental tissues, or to quantify the necessary force to extract a teeth from is socket

Presentamos nuestra experiencia en 17 procedimientos de cirugía laparoscópica sin neumoperitoneo. La aplicación de esta técnica ha implicado fabricar elementos de tracción de la pared abdominal como alambres y tractor regulable. Se han realizado 11 colecistectomías, 2 procedimientos urológicos y 4 ginecológicos. El análisis de este procedimiento ha demostrado tener una morbilidad menor que la técnica con neumoperitoneo, y una disminución considerable en los otros

Se presenta el caso de una niña de tres años y tres meses de edad quien a consecuencia de una caida sufrió luxación dorsal del atlas y ventral del axis sin fracturas. Lesión sumamente rara. Se hace la revisión bibliográfica al respecto, discutiéndose primordialmente os factores causales predisponentes.
