Interposition of Extensor Pollicis Longus Tendon in Smith's Fracture in a Child - A Case Report -

Abstract

Entrapment of the extensor pollicis longus tendon is reported rarely on Smith's fractures in children. In our case, a 15 year old boy with Smith's fracture received treatment of closed reduction at another hospital. When he visited our hospital, a wide gap at the fracture site was detected on radiograph and the thumb movement was limited. We have doubt the entrapment of the soft tissue, especially the tendon. We decided on open reduction. In the operation field, entrapment of the extensor pollicis longus tendon at the gap of the fracture site was found through dorsal approach. In addition, fracture treatment with K-wire fixation after reduction of extensonr pollicis longus tendon reduction was done. Therefore, we report this case with a review of the literatures.

Charge stripper effects on beam dynamics in the 180-degree bending section of the RISP linac

“…The RISP (rare-isotope science project) is developing a linac which can accelerate uranium beams to 200MeV/u with the beam power of 400 kW [1]. The linac consists of an injector and superconducting linac (SCL) as schematically shown in Figure 1.…”

Measurement error effects of beam parameters determined by beam profiles

“…The reference particle is the two charge state uranium beams, 238 U 33+,34+ with the kinetic energy of 10 keV/u from the ion source. The RFQ can accelerate heavy ion beams up to 500 keV/u and the beam power reaches 400 kW after SCL with the kinetic energy of 200 MeV/u [1,2].…”
