Quantitative measurement of disc space area before and after chemonucleolysis and nucleotomy.

Measurements of the area of the intervertebral disc space were made, over a period of 400 days or more, in 16 patients who underwent chemonucleolysis and 20 patients after nucleotomy. The superimpositioning method of measurement used is based on a determination of fixed points and it has a high level of reproducibility. We have measured areas which differ from volumes in only a single dimension, but which show good correlation compared with measurement of intervertebral disc space heights alone. After both chemonucleolysis and nucleotomy, narrowing of the intervertebral disc space occurs up to the 50th day, after which there is a highly significant difference: the intervertebral disc space height increases after chemonucleolysis, and continues to decrease after nucleotomy. It is concluded that the enzymatic effect of chymopapain on the nucleus pulposus produces a gain in disc substance after chemonucleolysis, whereas nucleotomy is associated with a loss of substance.

[The tenodesis of the peroneus muscle for the treatment of the chronic insufficiency of the lateral ligaments of the upper ankle joint (author's transl)].

Thirty-eight cases presenting with chronic instability of the ankle joint have been examined. Tenodesis using peroneus brevis has given satisfactory results in 29 cases and poor results in 9 cases (after the method of assessment by Weber). We have classified instability of the ankle joint in a functional way from Types I to III. In Type III, an extended form of tenodesis is required.

[Histological and Histomorphometric Changes after Osteotomies of Rabbit Tibiae Treated with Plate Osteosynthesis (author's transl)].

In all specimens the cross-sections of bone taken at 4 marked points showed atrophy of the cortical bone which had occured in a typical manner. In the 1-week specimens no qualitative changes could be observed by normal light microscopy. In the 2nd week, however, a vivacious bone remodelling with wide Haversian canals and vessels starts from the medial cortex as could be seen identically in every series of our experiments. In the 4th week and especially in the 6th week it becomes also apparent on the lateral, dorsal and ventral wall. In the 12th week bone remodelling is still active but obvious diminishing of the osteons can be observed between internal and external lamellae. In the 24th week only solitary enlarged sinus and few osteons are found medially and laterally. Alltogether the cortical bone has become very thin. The bone remodelling has stopped and this state is characterized by loss of osteons and abundance of intermediate lamellae. Already in the 1st week polarisation microscopy shows a certain demascating of the collagenous fibres opposite to the plate. The control specimens do not show changes of the collagenous structure in this area. In addition to these results histomorphometric investigations of 1-week specimens revealed a quantitative increase of Haversian canals which are located closer to the medullary space as well as to the side opposite the plate. This result is due to the fact that the bone remodelling starts from the cortex opposite to the metal implant.
