[A case of sesamoid bone fragmentation in the leg as the cause of lameness in a female Rottweiler]. / Ein Fall von Sesambeinfragmentierung als Lahmheitsursache bei einer Rottweilerhündin.

An eight-month-old female rottweiler was presented with a history of intermittent lameness of the right hindlimb of 4 weeks duration. Radiographs showed a fragmentation in two plantar sesamoid bones of the metatarsophalangeal joint. Based on these clinical and radiographic signs sesamoid disease of the 2nd and 7th sesamoid bone in the right hindpaw was diagnosed. The fragmented sesamoids were surgically removed and histologically examined. The treatment was successful and the dog became lamnessfree. Additional radiographs showed fragmentations of sesamoid bones VII of both the forepaws, but they did not cause any lameness.

[Avulsion of the origin of the tendon of the extensor digitalis longus muscle in a Dobermann pinscher]. / Avulsion der Ursprungssehne des Musculus extensor digitalis longus bei einem Dobermann.

Avulsion of the tendon of the extensor digitalis longus muscle is a rare condition in young, large breed dogs or as a consequence of chronic lateral patellar luxation in adult dogs. Current technique of fixation consists into reattaching the fragment with a lag screw at its origin in the extensor fossa of the lateral femur condyle. If the fragment was considered too friable and reactive to be reattached, it was amputated and the tendon was sutured to the joint capsula. In this present case a adaptation screw with a washer was inserted distally to the sulcus extensorius through the tendon. The proximal part of the tendon was sutured to the joint capsula. The postoperative result was excellent, with recovery of full function of the Musculus extensor digitalis longus.

Possible microwave mechanisms of the mammalian nervous system.

The hypothesis is examined that the living mammal generates and uses electromagnetic waves in the lower microwave frequency region as an integral part of the functioning of central and peripheral nervous systems. Analysis of the potential energy of a protein integral to the neural membrane compared to that of an extracellular positive ion yields major known features of action potential generation, and identification of the integral protein as a microwave emitter and absorber by changes in rotational energy state. Prolate spheroidal analysis of the adult human brain/skull cavity shows capability to support modes in the range 200 MHz to 3 GHz; spatial mode properties correspond to gross anatomy and neuromorphology of the brain. Phase-lock loop interaction between lower microwave modes and action potential conduction results in pulse microwave/action potential generation observable by EEG instrumentation as brain waves; alpha waves occur if the corpus callosum is the major neural tract involved. Spatially consistent Lorentz forces of standing microwaves provide physical basis for correspondence of spatial properties of microwave modes with brain anatomy, and for the formation of myelin sheath and the nodes of Ranvier on larger neurons.
