[The fixation of the flail chest with tension band wires (author's transl)].

A new technique of internal fixation of the flail chest was tested successfully in sheep. After reduction a 0.8 mm wire is passed twice intramedullary across the fracture and twisted under tension with two loops on the external side of the rib. This wire neutralizes bending and rotational forces and produces axial interfragmental compression. Combined with tension band wire fixation of an eventually fractures sternum it produced sufficient stability even in the very thin parasternal part of ribs. No respiratory support was necessary postoperatively. The method is simple and needs no special equipment.

[Development and application of a new polyurethane plastics support bandage (author's transl)].

Experiences with a newly developed plastics support bandage on 1007 patients are reported. A polyurethane hard foam composition developed specially for medical purposes was used, which is created by blending the two components A (polyol) and B (isocyanate). The principle of our support bandage lies in the fact that after being mixed in a 1:1 ratio, the two highly viscous components are packed into a cotton stocking having a high transverse elasticity. After being rolled out to the desired thickness, the stocking is wrapped around the extremity which it is to support, where it hardens out into a polyurethane hard foam composition. By reason of the moisture content of the scoured cotton stocking, a 1 to 2 mm thick layer of foam forms in the contact region and renders any further padding unnecessary. Correspondingly, by using a double chamber stocking, circular bandages have been produced which can be removed, by means of incorporated zip and interengaging hook fasteners. Reclining shells, abduction bandages and body corsets can be made in the same way. The physical properties of the support bandage are illustrated: apart from its low weight, the bandage is particularly advantageous by reason of its high strength, insensitivity to water and ideal permeability to X-rays. The support bandages are easily made up and entail negligible cost.

Utilization of magnetic resonance imaging in autopsy planning with specimen preservation for thoraco-omphalopagus symmetricus conjoined twins.

Conjoined twinning is a rare obstetric event that has fascinated physicians and laypersons alike for centuries. When this event occurs, early diagnosis, close prenatal management, and the proper route of delivery will assure the best possible outcome for mother and affected infants. Magnetic resonance imaging (MRI) is used both as an ancillary technique to the sonography for the antepartum diagnosis and in the preoperative planning for the surgical separation of conjoined twins. This report describes the MRI findings in conjoined twins of the thoraco-omphalopagus symmetricus type, a condition incompatible with extrauterine life. The twins were delivered at 21 weeks gestation. The MRI was used to evaluate the anatomic nature of the internal anomalies. These findings were then used to develop an autopsy approach plan that preserved the external phenotype. After dissection, the specimen was preserved by using polyethylene glycol and ultimately prepared for use as a teaching specimen.
