Callus distraction in the hand skeleton
Injury, 2000From 1992 to 1996, 27 patients with traumatic amputations or malformations underwent lengthening of thumb and fingers. A total of 36 procedures were carried out. In several cases, deepening of the web space or bone transplantations proved to be necessary to improve general function or to compensate for missing bone structure. Complications included pin-

Acoustic emission properties of callus
Medical & Biological Engineering & Computing, 198111 New Zealand white rabbits with 45 degree midshaft oblique osteotomies were stressed in shear while monitoring acoustic emission events. The ringdown counting method demonstrated a reasonably reproducible pattern when counting events against load; that is, each fracture remained essentially quiet until over 50% of load to failure had been applied ...

Lengthening of the Forearm by Callus Distraction
Journal of Hand Surgery, 1996Ten patients aged 3 to 13 years (mean, 9 years and 7 months) underwent forearm lengthening by callotasis. The indications for lengthening were shortening and/or deformity of the forearm due to exostosis of the distal ulna in five cases, enchondroma of the distal ulna in one, growth disturbance after fracture of the distal radius in one, radial club ...

STUDIES ON THE CALCIFICATION OF CALLUS
Archives of Surgery, 1923In a previously published article, I1reported the results of experiments which I had performed to determine the effect of variations in the blood phosphorus on the rate of calcification of callus in fractures. These experiments were made on the basis of reactions in vitro and with recent work on rickets as a background; and they were entirely negative.

First Metatarsal Callus Distraction
Journal of the American Podiatric Medical Association, 2008We describe the results in seven patients who underwent surgery to lengthen a short first metatarsal via callus distraction. The increased length achieved ranged from 13 to 48 mm, with an average of 20.2 mm. The technique was successful in restoring length and improving symptoms, although several complications were encountered.

Callus Induction in Grasses [PDF]
, 1989 The use of tissue culture techniques in the study of growth, metabolism, and differentiation has been widely developed for the dicotyledons, but the monocots, especially the grasses, have received little attention. One reason for this was that until recently the establishment of in vitro cultures of monocots was quite difficult.

The cartilaginous fracture callus in rats
Acta Orthopaedica Scandinavica, 1987The right tibia was broken manually in 56 rats weighing 100 g; the fracture was stabilized with an intramedullary steel wire. Groups of rats were killed after 3-30 days. The fracture with its surrounding musculature was dissected out and immediately frozen to -70 degrees C.

Cyclamen persicum callus cultures have been established on a defined medium. The tissue requires an auxin and a cytokinin. Adenine, while not required, greatly stimulates growth. The callus grows more vigorously in the dark than in light. After more than 6 years of subculture, the callus retains the capacity to form roots and shoots.

A series of intergeneric and interspecific graft unions were made between members of the Solanaceae for the purpose of studying the possibility of antibody production. The physiological and morphological changes in the graft unions treated from a purely immunological point of view will be considered elsewhere. The present publication deals with certain
